Run a event click after sucessful reload of a bootstrap table

I have this function, where I have a ajax call and in the success function, i have refresh the bootstrap table, now after the refresh i have a trigger command which i want to happen only when the refresh is done, how to do that,
success: function (result) {
console.log(result);
$('#overlay').hide();
swal({
title: result['msg'],
// text: result['text'],
type: result['type'],
showConfirmButton: true
});
$('#prospect_table').bootstrapTable('refresh');
element.parent('div').parent('div').parent('td').parent('tr').prev('tr').find('td:first').find('a').trigger('click')
}
the last event click happens at its specific time but I want to run that command only when the refresh is done,ie status=200
Thanks!
I have tried:
var evnCilck = element.parent('div').parent('div').parent('td').parent('tr').prev('tr').find('td:first').find('a').trigger('click'); // Or any other click function
$('#prospect_table').bootstrapTable('refresh', function(e){
evnCilck();
});
and
$('#prospect_table').bootstrapTable('refresh', function() {
element.parent('div').parent('div').parent('td').parent('tr').prev('tr').find('td:first').find('a').trigger('click');
});
No help from this.

You can do it like this
$('#prospect_table').bootstrapTable('refresh', function() {
element.parent('div').parent('div').parent('td').parent('tr').prev('tr').find('td:first').find('a').trigger('click');
});

Along with triggering an refresh event You also need to bind refresh eventlistener to the table like this :
var $table = $('#table');
$table.on('refresh.bs.table',function(){
// do your stuff here
element.parent('div').parent('div').parent('td').parent('tr').prev('tr').find('td:first').find('a').trigger('click');
})

You can do it by this way -
var evnCilck = element.parent('div').parent('div').parent('td').parent('tr').prev('tr').find('td:first').find('a').trigger('click'); // Or any other click function
$('#prospect_table').bootstrapTable('refresh', function(e){
evnCilck();
});

Ajax form is sent twice if validation errors take place

I know about event.preventDefault() and event.stopImmediatePropagation(). But it doesn't work for me. In my case I have such ajax call:
$('#templateConfirmDialog').on('show.bs.modal', function (event) {
$(this).find('.modal-yes').click(function(){
var form = form2js('search_form', '.', true, function (node) {}, false);
var requestData = JSON.stringify(form, replacer);
var $formErrors = $('.search_form').find('.alert-danger');
event.preventDefault();
event.stopImmediatePropagation();
$.ajax({
type: 'POST',
contentType : "application/json",
url: '/fraud/template/testCreate',
data: requestData,
dataType: 'json',
success: function (data) {
$formErrors.text('');
//if no errors just reload
if (data === undefined || data.length === 0) {
location.reload();
}
else {
//else bind error messages
data.forEach(function(error) {
$('#new-' + error.field + '-error').text(error.defaultMessage);
})
}
}
});
});
My problem is that the ajax call is prevented as much times as I made attempts to input data. If I entered invalid data once - ajax is called twice. If twice - 3 times. What may be a reason of such behavior?

Every time this event happens:
$('#templateConfirmDialog').on('show.bs.modal', function (event) {
You bind a new click event handler:
$(this).find('.modal-yes').click(function(){
So if you show.bs.modal twice, then you have two click event handlers both submitting the AJAX request. Instead, just bind the click event handler once to the target clickable element, instead of binding it every time the modal is displayed.
Replace this:
$('#templateConfirmDialog').on('show.bs.modal', function (event) {
$(this).find('.modal-yes').click(function(){
//...
});
});
With this:
$('#templateConfirmDialog').find('.modal-yes').click(function(){
//...
});
Or, if that element is dynamically added to the DOM, this:
$(document).on('click', '#templateConfirmDialog .modal-yes', function(){
//...
});
That way there's just a single click event handler created when the page loads, rather than adding a new handler every time you display the modal.

javascript/jquery doesn't work in ajax

I have php page "Home.php", that present user posts(using ajax).
This is how I get the posts:
<script type="text/javascript">
function loadmore()
{
var val = document.getElementById("result_no").value;
var userval = document.getElementById("user_id").value;
$.ajax({
type: 'post',
url: 'fetch.php',
data: {
getresult:val,
getuserid:userval
},
success: function (response) {
var content = document.getElementById("result_para");
content.innerHTML = content.innerHTML+response;
// We increase the value by 2 because we limit the results by 2
document.getElementById("result_no").value = Number(val)+10;
}
});
}
</script>
<div id="content">
<div id="result_para">
</div>
</div>
In every post, there is a like button(which also uses ajax). This is how I save the likes:
<script type="text/javascript">
function likethis(likepostid)
{
$.ajax({
type: 'post',
url: 'fetchlikes.php',
data: {
getpostid:likepostid
},
success: function (response) {
}
});
}
</script>
Before I used ajax to present posts, all worked well. But now when I press the like button, it DOES save the like, BUT the javascript/jquery doesn't work. I tried to make alert when I pressed the LIKE button, but it didn't work.
This is the index.js code(the javascript). It add +1 likes, when the user press the button:
$('.btn-counter_likecount').on('click', function(event, count) {
event.preventDefault();
//alert("hello");
var $this = $(this),
count = $this.attr('data-count'),
active = $this.hasClass('active'),
multiple = $this.hasClass('multiple-count_likecount');
$.fn.noop = $.noop;
$this.attr('data-count', ! active || multiple ? ++count : --count )[multiple ? 'noop' : 'toggleClass']('active');
});
EDIT fetchlikes.php:
<?php
mysql_connect('localhost','root','');
mysql_select_db('blabla');
$postid=$_POST['getpostid'];
mysql_query("UPDATE user_post SET likes_count=likes_count+1 WHERE post_id='$postid'");
?>

Because your posts are being loaded dynamically, the javascript where you bind the event is running before the posts are actually loaded, thus the buttons don't exist when you try to bind the event. You can use delegated events in jQuery to handle this.
Your previous code
$('.btn-counter_likecount').on('click', function(event, count) {
....
});
New Code
$('#result-para').on('click','.btn-counter_likecount',function(event, count) {
....
}
This way the event will actually be bound to a parent element that already exists when jQuery's ready() function runs. This way, the event handler checks for matching elements when the event is fired rather than when the event is bound.

JQuery conditional preventDefault() firing when not called

I have the following script I've written.
<script>
$(document).ready(function(){
$('a').data('loop',true);
$('body').on('click', 'a', function(event){
console.log($(this).data('loop'));
if ($(this).data('loop') == 'true') {
console.log('hit');
event.preventDefault();
caller = $(this);
$(this).data('loop',false);
var linkref = $(this).attr('href');
var linkpos = $(this).offset();
var screenwidth = $(window).width();
var json_data = JSON.stringify({linkref: linkref, linkpos: linkpos, screenwidth: screenwidth});
$.ajax({
url: "content/submitcontenthandler?handler=core/_dashboard&method=tracking_ping",
method: "POST",
data: "json=" + json_data,
complete: function (jqXHR, status) {
console.log(status);
console.log(caller);
$(caller).click();
}
});
} else {
console.log(event.isDefaultPrevented());
console.log('miss');
$(this).data('loop',true);
}
});
});
</script>
It works, sends me the details I want etc etc. BUT!!!
When I click a link, It fires off the details to me via Ajax, then it's meant to "click" the event again, which it does! but the event does not fire it's normal action. So When clicking a link to another page, I would go to that other page... that's not happening.
If I comment out the line event.preventDefault(); Then the event fires as I would expect...
So to me it looks like the event.preventDefault is executing even though it's not meant to be during the second call...
Sorry if this is a bit complicated to understand. I don't quite understand what's happening myself.
Is it possibly a bug, or is there something that I've done that has caused this?
I didn't think I could, but I have successfully made a jsfiddle for this.

You can try this and not worry about the "loop" anymore:
$(document).ready(function () {
$('body').on('click', 'a', function (event) {
event.preventDefault();
var caller = $(this);
var linkref = $(this).attr('href');
var linkpos = $(this).offset();
var screenwidth = $(window).width();
var json_data = JSON.stringify({linkref: linkref, linkpos: linkpos, screenwidth: screenwidth});
$.ajax({
url: "content/submitcontenthandler?handler=core/_dashboard&method=tracking_ping",
method: "POST",
data: "json=" + json_data,
complete: function (jqXHR, status) {
console.log(status);
console.log(caller);
window.location.href = linkref; // Redirect happens here
}
});
});
});
UPDATE
There's a few issues to note here:
1) Some links don't require a redirect (as noted, bootstrap model links that control showing/hiding or within document anchors
To correct this it really depends on the case. Usually bootstrap adds specific classes or data attributes to the links so you can do something like.
$('body').on('click', 'a:not(list of things to exclude)'..
Personally I'd instead define the links I wanted to track as :
<a href=<link> data-tracked='true'...
<script>
$('body').on("click","a[data-tracked='true']"...
Or if you want to track most links with a few exceptions you can:
<a href=<link> data-tracked='false'...
<script>
$('body').on("click","a:not([data-tracked='false'])"...
Or more generally:
<script>
$('body').on("click","a", function () {
if ($(this).attr("data-tracked") == "false" || <you can check more things here>){
return true; //Click passes through
}
//Rest of the tracking code here
});

The following if statement will return true whenever the data-loop attribute exists against an element, regardless of it's value:
if ($(this).data('loop')) {
It needs to be changed to check for the value:
if ($(this).data('loop') == 'true') {
When you assign anything to be the value of an element attribute it becomes a string and, as such, requires a string comparison.

Event.preventDefault() is not being executed second time.
Link redirection happens when the method is completed.
So in your case redirection will happen when complete method of ajax call is completed.
lets say, we have event1 and event2 object in the code. event1 is the object in the ajax call method and event2 is the event object in recursive call (second call) method.
so when link is clicked second time , we still have complete method to be executed. as soon as it returns to the complete method of ajax call, it finds the event1 is having preventDefault property true and it does not redirect.

Try this ;)
$(document).ready(function(){
$('body').on('click', 'a', function(event){
event.preventDefault();
var caller = $(this);
var linkref = $(this).attr('href');
var linkpos = $(this).offset();
var screenwidth = $(window).width();
var json_data = JSON.stringify({
linkref: linkref,
linkpos: linkpos,
screenwidth: screenwidth
});
$.ajax({
url: "content/submitcontenthandler?handler=core/_dashboard&method=tracking_ping",
method: "POST",
/* To temprary block browser; */
async: false,
data: "json=" + json_data,
complete: function(jqXHR, status){
/* add class **ignore** to a element you don't want to redirect anywhere(tabs, modals, dropdowns, etc); */
if(!caller.hasClass('ignore')){
/* Redirect happens here */
window.location.href = linkref;
}
}
});
});
});

jQuery event handler organisation

I am looking for a recommendation on the best way to organised my code. I have a lot of jQuery event handle which are used for:
dropdown menus, tabs etc
form validation
$.ajax get requests for dynamic form <options>'s
$.ajax post requests for form submitting.
An MVC framework like backbonejs seems like overkill but my current code isn't maintainable and will continue to get worse unless i give it some kind of structure.
$('#detailsform').find('.field').on('click','.save',function(){
var input = $(this).siblings().find('input');
input.attr('type','hidden');
$(this).siblings().find('p').text(input.val());
$(this).text('Change').addClass('change').removeClass('save');
url = null; //query str
$.ajax({
type: "POST",
url: url,
data: data,
success: success,
dataType: dataType
});
});
//next event listener
//next event listener
//next event listener
//next event listener
that is one of many event listeners. Any suggestions on how to organise this?

I would use the following structure. Simply add more objects in the eventHandlers array for each element you need. This could even be done programatically.
(function() {
var Site = {
init: function() {
this.bindEventHandlers();
},
bindEventHandlers: function() {
for (var i=0; i<this.eventHandlers.length; i++) {
this.bindEvent(this.eventHandlers[i]);
}
},
bindEvent: function(e) {
e.$el.on(e.event, e.handler);
console.log('Bound ' + e.event + ' handler for', e.$el);
},
eventHandlers: [
{
$el: $('#element1'),
event: "click",
handler: function() { console.log('Clicked',$(this)) }
},
{
$el: $('#element2'),
event: "click",
handler: function() { console.log('Clicked',$(this)) }
}
]
};
Site.init();
})();
