i pass a parameter to a page, and retrieve using the data-url attribute, it works fine. But, if i refresh that page, the url parameter will not be available. What should be done for this. Pls help.
You could store the url parameter in HTML5's localStorage. Generally, localStorage is supported by all browsers (including mobile) except IE, where it has some stability issues.
To store the url parameter,
window.localStorage.setItem("param", yourParam);
Then later, check if the item exists in the localStorage, if yes, get it from there and use.
if(window.localStorage["param"] != undefined)
{
var param= window.localStorage["param"];
}
Full workflow
var param = "", local = window.localStorage;
if(local["param"] != undefined)
{
param = local["param"];
}
else
{
//store the param in a database/in the server session and retrieve from there.
param = getFromServer();
//set item in localStorage
local.setItem("param", yourParam);
}

The workaround for this issue is to check whether the data("url") contains a question mark ?. If not you can retrieve the parameter values from the window.location.href.
This code:
$.mobile.changePage('car-details.html', {
data: {
id: 'my_id'
}
});
creates the URL: .../car-details.html?id=my_id
The below code handles the case of normal transition and the case of page refresh. In case of page refresh the parameter value is retrieved from window.location.href
var passedId = (($(this).data("url").indexOf("?") > 0) ? $(this).data("url") : window.location.href ).replace( /.*id=/, "" );

I am trying to do use the post method for a simple suitescript program, i am very new to this.
In Netsuite i have written a suitescript as follows.
function restPost()
{
var i = nlapiLoadRecord('department', 115);
var memo = nlapisetfieldvalue('custrecord225', ' ');// this is a customfield, which i want to populate the memo field, using rest client in firefox
var recordId = nlapiSubmitRecord(i);
}
i have created a script record and uploaded this suitescript and even copied the external URL to paste it in restclient.
In Restclient(firefox plugin), pasted the external URL, i have given the method as post, header authorization given, content-type: application/json, and in body i put in {"memo":"mynamehere"};
In this the error i get is
message": "missing ) after argument list
I even tried it by writting other suitescript programs the errors i get is as follows:
Unexpected token in object literal (null$lib#3) Empty JSON string
Invalid data format. You should return TEXT.
I am kinda new to the programming world, so any help would be really good.
I think you are trying to create a RESTlet for POST method. Following is the sample code for POST method -
function createRecord(datain)
{
var err = new Object();
// Validate if mandatory record type is set in the request
if (!datain.recordtype)
{
err.status = "failed";
err.message= "missing recordtype";
return err;
}
var record = nlapiCreateRecord(datain.recordtype);
for (var fieldname in datain)
{
if (datain.hasOwnProperty(fieldname))
{
if (fieldname != 'recordtype' && fieldname != 'id')
{
var value = datain[fieldname];
if (value && typeof value != 'object') // ignore other type of parameters
{
record.setFieldValue(fieldname, value);
}
}
}
}
var recordId = nlapiSubmitRecord(record);
nlapiLogExecution('DEBUG','id='+recordId);
var nlobj = nlapiLoadRecord(datain.recordtype,recordId);
return nlobj;
}
So after deploying this RESTlet you can call this POST method by passing following sample JSON payload -
{"recordtype":"customer","entityid":"John Doe","companyname":"ABCTools Inc","subsidiary":"1","email":"jdoe#email.com"}
For Authorization you have to pass request headers as follows -
var headers = {
"Authorization": "NLAuth nlauth_account=" + cred.account + ", nlauth_email=" + cred.email +
", nlauth_signature= " + cred.password + ", nlauth_role=" + cred.role,
"Content-Type": "application/json"};
I can understand your requirement and the answer posted by Parsun & NetSuite-Expert is good. You can follow that code. That is a generic code that can accept any master record without child records. For Example Customer Without Contact or Addressbook.
I would like to suggest a small change in the code and i have given it in my solution.
Changes Below
var isExistRec = isExistingRecord(objDataIn);
var record = (isExistRec) ? nlapiLoadRecord(objDataIn.recordtype, objDataIn.internalid, {
recordmode: 'dynamic'
}) : nlapiCreateRecord(objDataIn.recordtype);
//Check for Record is Existing in Netsuite or Not using a custom function
function isExistingRecord(objDataIn) {
if (objDataIn.internalid != null && objDataIn.internalid != '' && objDataIn.internalid.trim().length > 0)
return true;
else
return false;
}
So whenever you pass JSON data to the REStlet, keep in mind you have
to pass the internalid, recordtype as mandatory values.
Thanks

I believe you will want to return something from your function. An empty object should do fine, or something like {success : true}.
Welcome to Netsuite Suitescripting #Vin :)
I strongly recommend to go through SuiteScript API Overview & SuiteScript API - Alphabetized Index in NS help Center, which is the only and most obvious place to learn the basics of Suitescripting.
nlapiLoadRecord(type, id, initializeValues)
Loads an existing record from the system and returns an nlobjRecord object containing all the field data for that record. You can then extract the desired information from the loaded record using the methods available on the returned record object. This API is a core API. It is available in both client and server contexts.
function restPost(dataIn) {
var record = nlapiLoadRecord('department', 115); // returns nlobjRecord
record.setFieldValue('custrecord225', dataIn.memo); // set the value in custom field
var recordId = nlapiSubmitRecord(record);
return recordId;
}
I am currently focussing a problem which I thought it would be easy to solve. but I didnt. There are controls which allow us to show the username or logged in user, such as the lovely shell-headitems:
var oShell = new sap.ui.ux3.Shell("myShell", {
headerItems: [
new sap.ui.commons.TextView({
text: oController.getUserName() }),
],
});
It looks like this:
In here we define headerItems, which are in my opinion foreseen to show a username / or the currently logged in user. but how can I receive it? my idea is to get it from the odata request, which was made earlier. It requires me to enter username and password -> thus I want to read this username in my controller-method, but how?
getUserName : function() {
// return navigator.userAgent;
var model = sap.ui.getCore().getModel();
return model.getProperty('sUser'); // doesnt work :(
},
I also tried to get it from navigator.userAgent() but this information does not belong to the user.
Anybody knows how to receive it?
And yes: I searched in google and found some threads discussing about users/login but none of these threads solved my issue. Otherwise I thought about transferring sy-uname from SAP to the frontend, but how could you send a single Text? I don't want to build a complete service for this single transaction.
If you do not provide sUser and sPassword during oData-Model-Initialization it will be empty during runtime. You cannot access it from the model, though I realized an own service for this.
The username is in the sap.ui.model.odata.ODataMetadata of ODataModel.
var getUserName = function() {
var model = sap.ui.getCore().getModel();
var sUser = model.oMetadata.sUser;
// Display user logic here.
};
oModel.attachMetadataLoaded(null,getUserName);
Update answer for comment question from zyrex:
var user = new sap.ui.commons.TextView();
var getUserNameCallBack = function(userName) {
user.setText(userName);
}
oController.getUserName(getUserNameCallBack);
Controller method:
getUserName: function(callback) {
var userName = '';
$.getJSON(sServiceUrl).done(function(data) {
userName = data.d.Name;
callback(userName);
});
}
This is my Titanium code:
var loginReq = Titanium.Network.createHTTPClient({
onload: function(e){
// just displays the response
var webview = Titanium.UI.createWebView({html:this.responseText});
win.add(webview);
}
});
loginReq.open("POST",url);
var params = {
email: email.value,
passowrd: password.value
};
loginReq.send(params); // this is sending nothing according to a CF variable dump
The ColdFusion page just dumps all the variables, and it shows up on the iPhone emulator. But it's giving me an empty struct for the variables, which means no variables are actually getting sent in.
How do I fix my Titanium code to actually post data?
If you want to send post data to a script you will have to to set the header accordingly:
loginReq.setRequestHeader("Content-Type","application/x-www-form-urlencoded");
If you are sending JSON data to an API, you might need to stringify your parameters to send them:
loginReq.send(JSON.stringify(params));
Edit:
According to the docs this is done automatically (see comments). In some of my network clients I had to do that explicitly, though...
Moreover, you might also want to implement the onerror callback, so in case your call fails for any reason you will know why:
var loginReq = Titanium.Network.createHTTPClient({
onload: function(e){
// just displays the response
var webview = Titanium.UI.createWebView({html:this.responseText});
win.add(webview);
},
onerror: function(e) {
Ti.API.debug('Status: ' + this.status);
Ti.API.debug('Response: ' + this.responseText);
}
});
I want to parse tweets with this function with content served via Node.js/Express/Jade client side.
String.prototype.parseHashtag = function() {
return this.replace(/[#]+[A-Za-z0-9-_]+/g, function(t) {
var tag = t.replace("#","%23")
return t.link("http://search.twitter.com/search?q="+tag);
});
};
I would like to do it client side so that for example when a new tweet is added that can be parsed to with the same code and displayed directly and not have to go back and forth to the backend and be parsed.
I've made it work with this code, but is there any way to make it simpler, prettier?
!= "<script type='text/javascript'>"
!= "var body = '"
= contents[c].body
!= "';"
!= "document.write(body.parseHashtag());"
!= "</script>"
Yes you can. I will suggest you the following way:
script(type='text/javascript')
var body = contents[c].body;
document.write(body.parseHashtag());
you should also see jade documentation for it:enter link description here
I built an ajax chat in one of my mvc website. everything is working fine. I am using polling. At certain interval i am using $.post to get the messages from the db. But there is a problem. The message retrieved using $.post keeps on repeating. here is my javascript code and controller method.
var t;
function GetMessages() {
var LastMsgRec = $("#hdnLastMsgRec").val();
var RoomId = $("#hdnRoomId").val();
//Get all the messages associated with this roomId
$.post("/Chat/GetMessages", { roomId: RoomId, lastRecMsg: LastMsgRec }, function(Data) {
if (Data.Messages.length != 0) {
$("#messagesCont").append(Data.Messages);
if (Data.newUser.length != 0)
$("#usersUl").append(Data.newUser);
$("#messagesCont").attr({ scrollTop: $("#messagesCont").attr("scrollHeight") - $('#messagesCont').height() });
$("#userListCont").attr({ scrollTop: $("#userListCont").attr("scrollHeight") - $('#userListCont').height() });
}
else {
}
$("#hdnLastMsgRec").val(Data.LastMsgRec);
}, "json");
t = setTimeout("GetMessages()", 3000);
}
and here is my controller method to get the data:
public JsonResult GetMessages(int roomId,DateTime lastRecMsg)
{
StringBuilder messagesSb = new StringBuilder();
StringBuilder newUserSb = new StringBuilder();
List<Message> msgs = (dc.Messages).Where(m => m.RoomID == roomId && m.TimeStamp > lastRecMsg).ToList();
if (msgs.Count == 0)
{
return Json(new { Messages = "", LastMsgRec = System.DateTime.Now.ToString() });
}
foreach (Message item in msgs)
{
messagesSb.Append(string.Format(messageTemplate,item.User.Username,item.Text));
if (item.Text == "Just logged in!")
newUserSb.Append(string.Format(newUserTemplate,item.User.Username));
}
return Json(new {Messages = messagesSb.ToString(),LastMsgRec = System.DateTime.Now.ToString(),newUser = newUserSb.ToString().Length == 0 ?"":newUserSb.ToString()});
}
Everything is working absloutely perfect. But i some messages getting repeated. The first time page loads i am retrieving the data and call GetMessages() function. I am loading the value of field hdnLastMsgRec the first time page loads and after the value for this field are set by the javascript.
I think the message keeps on repeating because of asynchronous calls. I don't know, may be you guys can help me solve this.
or you can suggest better way to implement this.
Kaivalya is correct about the caching, but I'd also suggest that your design could and should be altered just a tad.
I made a very similar app recently, and what I found was that my design was greatly enhanced by letting the controllers work with the fairly standard PRG pattern (post-redirect-get). Why enhanced? well, because POST methods are built to add stuff to an app, GET methods are supposed to be used to get information without side effects. Your polling should be just getting new messages w/o side effects.
So rather than your $.post call expecting data and handling the callback, what I'd recommend is having your controller expose a method for creating new chat messages via POST and then another method that get the last X chat messages, or the messages since a certain timestamp or whatever.
The javascript callback from the post action, then can update some variables (e.g. the last message id, timestamp of the last message, or even the whole URL of the next message based on the info contained in a redirect, whatever).
The $.post would fire only in response to user input (e..g type in a box, hit 'send') Then, you have (separately) a $.get call from jquery that's set up to poll like you said, and all it does is fetch the latest chat messages and it's callback updates the chat UI with them.
I got my answer here: ASP.NET AJAX CHAT
The names below i am referring to are from above link.
i think the actual problem was with the timestamp thing and asynchronous behaviour of $.post. after calling "GetMessages()" method, even if the previous request to retrive chat message was not complete anathor call to same method used to fire due to setting timeout for "GetMessages()" method outside the $.post method. In my question you can see that timeout for "GetMessages()" method is set outside the $.post method. Now i set the timeout for "GetMessages()" method inside the $.post method. so that next call to "GetMessages()" only occur after 3 seconds of completion of current $.post method. I have posted the code below.
var t;
function GetMessages() {
var LastMsgRec = $("#hdnLastMsgRec").val();
var RoomId = $("#hdnRoomId").val();
//Get all the messages associated with this roomId
$.post("/Chat/GetMessages", { roomId: RoomId, lastRecMsg: LastMsgRec }, function(Data) {
if (Data.LastMsgRec.length != 0)
$("#hdnLastMsgRec").val(Data.LastMsgRec);
if (Data.Messages.length != 0) {
$("#messagesCont").append(Data.Messages);
if (Data.newUser.length != 0)
$("#usersUl").append(Data.newUser);
$("#messagesCont").attr({ scrollTop: $("#messagesCont").attr("scrollHeight") - $('#messagesCont').height() });
$("#userListCont").attr({ scrollTop: $("#userListCont").attr("scrollHeight") - $('#userListCont').height() });
}
else {
}
t = setTimeout("GetMessages()", 3000);
}, "json");
}
I addition to that i also changed few things. As suggested by ignatandrei i placed $("#hdnLastMsgRec").val(Data.LastMsgRec); immediately after function(Data) {.
and also
as said by MikeSW i changed the data retrieval process. Previously i was extracting data on the basis of timespan(retrieve all the data associated with
this room id that has greater timespan than last data retrieved message timespan) but now i keep track of the messageid. Now i retrieve only those data that
has message id greater than last retrieved message id.
and guess what no repeataion and perfectly working chat application so far on my intranet.
I still got to see it's performance when deployed on internet.
i think it solved my problem.
i will still test the system and let u guys know if there is any problem.
By default $.post() caches the results
You can either call $.ajaxSetup ({ cache: false}); before JS GetMessages function call to ensure caching is disabled or change the $.post to $.ajax and set cache attribute to false. In the end $.post() is a short cut to this:
$.ajax({
type: 'POST',
url: url,
data: data,
success: success
dataType: dataType
});
