I currently update entries to my fusion table with the following AJAX call:
$.ajax({
type: "POST",
url: "https://www.googleapis.com/fusiontables/v1/query?sql=UPDATE <my TABLE ID> SET columnName = 'newValue' WHERE ROWID = '2'&key=<API KEY GOES HERE>",
beforeSend: function(xhr) {
xhr.setRequestHeader("Authorization", "Bearer <AUTHENTICATION TOKEN GOES HERE>");
},
success: function(data) {
alert(data);
}
})
and it works great!
but I do not want to replace the contents of the entry, I want to append data. Is there a way to do this without calling the data from the cell I want to modify (i.e., do it in one statement)
To insert data in a fusiontable, you should use an INSERT statement, see the SQL Reference Documentation of the Fusion Tables API.
INSERT
To insert one or more rows in a table, use the following syntax in an
HTTP POST request:
INSERT INTO ( {, }) VALUES
( {, }) { {;INSERT INTO ( {,
}) VALUES ( {, })}* ;}

I am calling a simple query with findOne, so far the data in users.db is:
{"id":40, "is_admin":1,"name":"John Smith"},
{"id":43, "is_admin":1,"name":"Laura Smith"}
// Users
var users = new Datastore({ filename: 'db/users.db' });
var id_user = 43;
console.log("-------------geting users db");
//
users.loadDatabase(function (err) {
console.log("------------- users db loaded--", id_user);
// find user by id
users.findOne({ id: id_user }, function (err, a,b,c) {
console.log(a,b,c); // displays null undefined undefined
});
});
Any idea why is returning null?
I think function being passed in findOne should take 2 parameters. First parameter will be the result of query and
second parameter will be error if something goes wrong . First parameter will be Null if there is no match in db .otherwise it should return the match result.
Function(result, error ){
}
It will be you function prototype
I tested your code in my app
db.findOne({ "c2cId":"292" }, function (err, a,b,c) {
console.log(a,b,c);
});
It return one doc and undefined, undefined.
If you use findOne I guess you just want to find the first doc, so looking at the
doc at
You can see there is only two parameters err and the doc
Concerning the null: in your query are you using a variable named id? or is it the key, in last case you should use quotes....
i have a datatable which i'm loading via Ajax.
in the server side i'm prepering the data for the table and prepare another data for another thing
i want, beside the table loading, to do another thing with the other data i've prepared
so i added to my ajax code a success event, but it replace the table loading and i only can do the other thing
i can't separate between the table loading and the other thing because they are connected, meanning the other thing is influenced by the table loading(changes)
i tried also fnDrawCallback but i don't know how to pass the data of the other thing
Here's the Ajax code with success event:
"ajax": {
"url": "/Entreaties/GetEntreaties",
"data": function (d) {
d.status = 0;
d.firstLoad = firstLoad;
d.jAdvanceSearch = JSON.stringify(new AdvanceSearch());
d.freeText = $("#table_filter input").val();
},
"type": "POST",
"dataType": "json",
success: function (data) {
$.each(data.contactWaySum, function (key, value) {
alert(key + ": " + value.ContactWay);
});
},
error: function (xhr, textStatus, errorThrown) {
console.log(xhr.responseText);
}
},
Thank you all for your help
If I understand you right, you were using the built in DataTable ajax but stopped because you wanted to do several things at once. If so, go back to using the DataTable ajax and used the dataFilter function to separate them out and apply them.
Here is an example:
// If your server side sends back somehting that looks like this for the data table (this is what it is expecting)
{draw:1, recordTotal:20, recordsFilter:20, data:dataSet }
// adjust your json to look like
// If the json object return looks like what the
{ dataTableData:{draw:1, recordTotal:20, recordsFilter:20, data:dataSet }, otherStuffData: otherData}
$("#sometable").DataTable({
// other data table stuff left out to save space
"serverSide": true,
"ajax": {
"url": "you url" ,
"data": function (ssp) {
// Do the stuff you need to to get your paramerters ready
// server side parameters (ssp) are documented at http://datatables.net/manual/server-side
// in addition to the ssp parameters, the name of the column is pulled from the table header column
return ssp;
},
type: "POST",
contentType: "application/json; charset=utf-8",
dataType: "json",
error: function (a, b, c, d) { debugger; },
dataFilter: function (data) {
// call function or what ever you need to do with the other data here
doOtherStuff(data.otherStuffData);
// the web method returns the data in a wrapper
// so it has to be pulled out and put in the
// form that DataTables is expecting.
//return just the datatable data here
return JSON.stringify( data.dataTableData);
}
}
});
I have an MVC PagedList which works just fine. I am filtering that list and the filter predicate is sent to the client during roundtrips. I use unobtusive ajax replacing. My pager code looks as:
#Html.PagedListPager((IPagedList)Model.Items,
page => Url.Action("Filter",
new ClientSearch
{
Page = page,
PageSize = Model.PageSize,
Predicate = Model.Predicate
}),
PagedListRenderOptions.EnableUnobtrusiveAjaxReplacing(
new AjaxOptions
{
HttpMethod = "POST",
UpdateTargetId = "clients-list",
}))
The problem is, that the Predicate parameter is too long. And it should be. I get the following exception:
"The request filtering module is configured to deny a request where the query string is too long."
I do not want to alter the web.config in order to allow long parameters. I would like to pass the model in a POST header instead of query string parameter. Is it possible with PagedList?
Thanks in advance.
I still couldn't figure out whether PagedList supported posting large data, however I ended up with the following workaround.
I have a post method which posts the model to the controller function and replaces the partial view content with the results.
function postToPage(url, size, predicate, replace) {
var data = {
size: size,
predicate: predicate
};
$.ajax({
url: url,
data: data,
type: 'POST',
success: function (result) {
$('#' + replace).html(result);
}
});
}
I also have another function to replace the URLs in the pagination-container div and wire up the click event to call the post method. The click event stops event propagation, so the URL in the href attribute won't be used.
function replaceHrefs() {
$('div[class = pagination-container').find('a').each(function (index, value) {
var url = value.href.toString();
value.addEventListener('click', function (event) {
event.stopPropagation();
post(url);
});
value.href = '#';
});
I created a custom version of post method in order to generate the pagesize and predicate from the model.
function post(url) {
postToPage(url, #Model.PageSize, '#Model.Predicate', 'clients-list');
}
I had to wire up the URL replacing procedure to two places: when the document becomes ready and when the ajax call completes. These covered all the cases I needed.
$( document ).ajaxComplete(function() {
replaceHrefs();
});
$( document ).ready(function() {
replaceHrefs();
});
I hope it helps someone.
I have spent the last couple of hours battling to write some javascript and jquery.
Basically I am trying to loop through a table checking if an attribute exists within a TD if it does add its info into an array and post it back to the server
My code (I am sure it could be better)
$("#save-changes").click(function () {
var param = [];
var table = $("#products-grid > .t-grid-content > table tbody tr").each(function (i) {
//find checkboxes using class
var td = ($(this).find("td:nth-child(2)").find(".cb"));
var attr = $(td).attr('data-item');
if (typeof attr !== 'undefined' && attr !== false) {
console.log(td);
param.push({ "itemId": attr, "productId": td.val() });
}
});
console.log(param);
$.ajax({
url: '#Url.Action("ApplyProduct")',
data: param,
type: 'POST',
success: function (e) {
I am now stuck on trying to pass the array back to the server. What do I need to do to send the data back to the server as a parameter the server can understand?
Any help would be great!
add two parameters
dataType: "json",
data: JSON.stringify(param)
to your .ajax call.
Crate an object server side which has two int properties int called itemId and productId and then create a JsonResult route that takes an array of your object that you post too (this would be ApplyProduct in your case).
you cannot send arrays to a server , they have to be strings.
you could join the array together like this
param.join(";");
that would create a string with each value seperated by a ;
also you need to specify the data option as a key-value json
$.ajax({
url: '#Url.Action("ApplyProduct")',
data: {
param : param
},
type: 'POST',
then on the serverside you can split the string back into an array
$param = explode(";",$_POST['param']);
In my web app , I am showing rates of stocks.I am using jquery autocomplete to show options while entring stocks name. But I have built local copy of javascript array. I want to show the options from this local array , If search term is not found in local array then ajax call must be made to get the list from server side.
Thanks !!!
//Local array
var local_array=["option1","option2"];
//jqueryUI call of autocomplete function
$('#search_stock').autocomplete({
source:function(){
if(search term is found in local array)
{
show suggestion from local array.
}
else
{
make ajax call to show suggestions of stock names.
}
}
});
UPDATE
Here's the actual code
$(function() {
var cache = {'option1':'option1','option2':'option2'}, lastXhr;
$( "#stock_rates" ).autocomplete({
minLength: 2,
source: function( request, response ) {
var term = request.term;
if ( term in cache ) {
response( cache[ term ] );
return;
}
lastXhr = $.getJSON( "stock_rates.php", request, function( data, status, xhr ) {
cache[ term ] = data;
if ( xhr === lastXhr ) { response( data ); }
});
}
});
});
The example pages for jQuery UI autocomplete have an example of exactly this issue.
http://jqueryui.com/demos/autocomplete/#remote-with-cache. Click the 'View Source' link on that page to see the code for the example.
The key part is that 'source' takes arguments.
source: function(request, response){
You need to read request, either fetch the value from your cache, or do a request, and then call the response function and pass it the matched values.
Update
Your problem now is that the format that you are storing in your cache is wrong. The cache just stores data as it would be returned from your getJSON call, indexed by the search term. It is up to you do to do the prefix checking and such.
To continue the way you are trying now, you'll either need to populate the cache properly.
var cache = {
"o": ['option1', 'option2'],
"op": ['option1', 'option2'],
// ....
"option1": ['option1'],
"option2": ['option2']
};
Otherwise, you could store the data differently and put more logic in your 'source' function to do the prefix checking on a static array or something. That all really depends on the data you are caching though.
Use search event of autocomplete and check your condition in that event and based on that return true or false if you want to make a ajax call respectively.
Below is the sample code.
$('#search_stock').autocomplete({
search:function(event,ui){
if(search term is found in local array)
{
return false;
}
else
{
return true;
}
}
});
