I am attempting to use Select2 in tag mode. It appears the createTag and insertTag functions are called on every key press when entering a new tag. Is it possible to only create a tag when the user selects the new option/tag (either via mouse or keyboard)? I have some processing to do with the tags as they are entered, but only when the user deems them complete.
$(this.select).select2({
tags: true,
createTag: function (params) {
console.log(params.term);
return {
id: params.term,
text: params.term,
newTag: true
}
},
insertTag: function (data, tag) {
console.log(tag.text);
data.push(tag);
}
});
This logs every single keystroke.
Turns out it's the simple change event which fires when the user has finished entering a tag - listening to that allowed me to do the required processing before the option was selected.

I use select2 for specifying recipients for the website's inner messaging system. There are users and they can send messages to each other. They can search other users by the user name.
I use the following config:
this.$select2.select2({
multiple: true,
ajax: {
url: "/userSearch",
dataType: "json",
},
templateResult: function(data) {
var user = new SomeComplexUserModel(data);
var $div = $(<div></div>");
$div.append("<img src='"+user.image.readPaths().crop+"'>");
$div.append("<span>"+user.fullName()+"</span>");
return $div;
},
templateSelection: ..the same as templateResult..
Now I want to set initial value for this. How to do that? I have the list of ids of the users that have to be selected on page load. I make the separate request to /userSearch and receive the data. Then I'm trying to push this data to the select2 somehow.
I can't create native var opt = new Option(text,value); select.append(opt) because this case templateSelection gets only id and text from the option, it can't construct the user model based on this data only. It does not show users with avatars.
I tried to trigger select2:select event with {originalEvent:null,data:$.extend(ajaxResult,{selected:true,disabled:false,element:null},_type:"select")}, but it seems it does not work this direction. It emits events but is not subscribed for them.
I also tried to set this.$select2.val(ajaxData); this.$select2.trigger('change'), after select2 initialization, but it does not work either.
I have a table where users are allowed to "tick" or "cross" out a row. Ticking a row changes the status value to "Approved" and crossing it changes it to "Disapproved". I'm currently using the Edit scaffold to perform it. How do I do this without having the user being redirected to the view. I just want the user to click it and the page refreshes, with the status value being updated.
I'm not sure what code to post here either since I don't know how to write it. If any part of my program is required, please let me know. I'll include it here. Thank you :>
Add css classes to the 2 buttons "approve-btn" and "reject-btn".
Create javascript function to approve and reject and bind them to
the 2 classes
Create 2 backend functions
Make ajax calls from the JS functions to your backend functions passing the id of the row item
In the "success:" of the ajax call manage the change of the status to show "approved" or "rejected"
To make ajax call you can use the following example (although there are tons of example on google). Since you're modifying data you should use POST call and since it is a POST call, you should add a RequestVerificationToken to prevent CSRF attacks.
function Approve(id){
securityToken = $('[name=__RequestVerificationToken]').val();
$.ajax({
url: '/YourControllerName/Approve/' + itemId,
type: 'POST',
data: {
"__RequestVerificationToken": securityToken
},
success: function (data) {
if (data == 'success')
//use jQuery to show the approved message;
else
alert("something went wrong");
},
error: function (request, err) {
alert("something went wrong");
}
});
}
The Token should be created in the View adding this line:
#Html.AntiForgeryToken()
i am working on a project which is based on jquery Mobile. i am a biggner in this field, so sorry for the silly question. the question is -- i have a page 'Page1' and i am using post method to fetch data from database. On success i am showing a notification to user through a notification dialog(without cancel and ok button). now what i want this success message on another page "page2", and the message should be there up to 2 sec and then disappear automatically. i have tried
function sendAddGuest(data, dialog) {
$.post("/GuestsList/AddGuest", data, function (response) { //using the post method
//alert(JSON.stringify(response));
$('.error').html("");
hideLoading();
if (response.result == 'success') { //if the process done
$.mobile.changePage('/GuestsList/Index', { dataUrl: "/GuestsList/Index", reloadPage: false, changeHash: true }); //To another page "page2"
// window.setTimeout('showToastMessage("Guest added successfully with window");',2000); //i have tried this
setTimeout(function () { showToastMessage("Guest added successfully test2"); }, 100); //and this also i want to show this message on other page "page2"
}
}
I am also beginning with Jquery Mobile, based in the toy project I am working with I would suggest the following:
Use popup from jquerymobile instead of showToast, then you could call
the .close() of the element in the settimeout function.
This is the div you create for your popup (you put it in the page 2):
<div data-role="popup" id="myPopup" class="ui-content" data-theme="e">
<p>Guest added successfully</p>
</div>
This is how you could call the function to open once in the new page (use the pageload event):
$('#myPopup').popup('open');
This is how you could call the function to close (in the same pageload event):
window.setTimeout(function(){ $('#myPopup').popup('close'); }, 2000)
Sorry I have no time to code a complete example, but I think this is the way to go.
Hope this helps!:-)
I have an ASP.NET MVC 3.0 partial view which is render inside a jquery ui dialog.
Inside this partial view I have some link which help me to display some more info.
#foreach (StatusType status in ViewBag.Status)
{
<li>#status.StatusMessage<a href='#' status='#status.StatusCode'><img src=#Url.Content("~/Content/Images/information.png") alt="See detail"/></a></li>
}
I've bound those link with the click event:
$('a[status]').live('click', function (e) {
if (e.preventDefault)
e.preventDefault();
else
e.returnValue = false;
var status = $(this).attr('status');
alert('#Model.Code');
...});
What is happening is when I click the first time on the link it will display me the correct Code (let's say 12). When I will load the partial view again for another code (66) it will display me two alert message, the first one with 12 (the old value I've clicked before) and the second one with 66.
The more partial view I will load the more value I will have in my alert.
I don't understand why it is keeping me like an history of all the code I've clicked.
If somebody have any idea on this problem, it will be welcomed, it just driving me mad.
Thanks in advance.
UPDATED
The use of the on instead of the live works, but I still have an issue with the dialog.
I've change the code with the solution proposed:
$('#StatusDiv').on('click', 'a[status]', function (e) {
e.preventDefault();
var status = $(this).attr('status');
alert('#Model.Code');
$('#StatusDialog').dialog({
autoOpen: false,
width: 800,
resizable: true,
title: 'Status Info',
modal: true,
open: function (event, ui) {
alert('#Model.Code');
$(this).load('#Url.Action("ViewStatusInfo")', { clientId: clientId, Code: '#Model.Code', status: status
});
}
});
$('#StatusDialog').dialog('open');
});
The first alert display the correct code, but the second alert inside the open function display the old one. On the second click it will work correctly but I don't understand how it can pick the old value since the first display is correct...
Thanks again for your help.
First of all: do not use live in last versions of jquery.
$('#list').on('click', '.status', function(e){
e.preventDefault();
alert(this.href);
});
Here we bind event to #list and when we will insert new links, everything will work.

I've got a Google Searchbar-type input field. When I type in a couple characters and wait for half a second it runs the ajax call to an external website I've set in the "source" function of the autocomplete code and once it has returned the results it returns it to the screen (like it should).
The problem is that while the ajax call is being run to fetch the results it won't allow me to continue typing in the input field until the ajax call has completed.
How can I get it to allow me to continue typing while the ajax call is being made?
Here is my jQuery function:
$('#googleSearchbar').autocomplete({
minLength: 2,
autoFocus: true,
delay: 500,
source: function (request, response) {
results = $.parseJSON($(this).callJson('post', 'http://my_external_url', {
data: request.term
}));
response(results);
},
error: function (err) {
console.error('ERROR : ' + err);
return false;
}
});
I have a hunch you are blocking the browser when making your AJAX request. This line:
results = $.parseJSON($(this).callJson('post', 'http://my_external_url', {
data: request.term
}));
Makes me think that $(this).callJson(...) is a synchronous request, which is going to lock up the entire browser for the duration of the request.
You need to make an asynchronous request and call the response function when that request completes. This should stop the browser from locking up.
