On a page with a tab control, each tab contains a table, each tr contains a td with a button which has a value assigned to it.
<td>
<button type="button" class="btn" name="deleteEventBtn" value="1">Delete</button>
</td>
This code below works for the first delete. After the AJAX call & the refresh of the div, no further delete buttons can be clicked. The .on is attached to the document. The same happens if I attach it to the body or anything closer to the buttons.
function deleteRecord(url, id, container) {
$.ajax({
type: "POST",
url: url,
data: { id: id },
success: function (data) {
$('#delete-popup').hide();
$(container).trigger('refresh');
}
});
}
$(document).ready(function () {
$(document).on('click', '[name^="delete"]', function (e) {
e.preventDefault();
var id = $(this).val();
$('#current-record-id').val(id);
$('#delete-popup').modal('show');
});
$('#delete-btn-yes').on('click', function (e) {
e.preventDefault();
var recordId = $('#current-record-id').val();
var recordType = location.hash;
switch (recordType) {
case "#personList":
deleteRecord(url, recordId, recordType);
break;
}
});
});
Any ideas? Could it be related to the wildcard for starts with [name^="delete"]? There are no other elements where the name starts with 'delete'.
EDIT
When replacing
$(container).trigger('refresh');
with
location.reload();
it "works", however that refreshes the whole page, loses the users position and defeats the point of using AJAX.
As the button click is firing at first attempt, there is no issue in that code. All you have to do is, put the button click event in a method and call it after the refresh. This way, the events will be attached to the element again. See the code below,
function deleteRecord(url, id, container) {
$.ajax({
type: "POST",
url: url,
data: { id: id },
success: function (data) {
$('#delete-popup').hide();
$(container).trigger('refresh');
BindEvents();
}
});
}
$(document).ready(function () {
BindEvents();
});
function BindEvents()
{
$(document).on('click', '[name^="delete"]', function (e) {
e.preventDefault();
var id = $(this).val();
$('#current-record-id').val(id);
$('#delete-popup').modal('show');
});
$('#delete-btn-yes').on('click', function (e) {
e.preventDefault();
var recordId = $('#current-record-id').val();
var recordType = location.hash;
switch (recordType) {
case "#personList":
deleteRecord(url, recordId, recordType);
break;
});
}
Apologies to all and thanks for your answers. The problem was due to the way the popup was being shown & hidden.
$('#delete-popup').modal('show');
and
$('#delete-popup').hide();
When I changed this line to:
$('#delete-popup').modal('hide');
it worked. Thanks to LShetty, the alert (in the right place) did help!
If you are using Bootstrap Modal
After Ajax Request before Refreshing page add
$('.modal').modal('hide');
This Line will Close your Modal and reload your page. Before that it will complete all Ajax Request things.
But for google chrome there is no issues :) hope this help someone.

I have a table with data and a function to help me get values from rows:
function getRow () {
$('#mytable').find('tr').click( function(){
let fname = $(this).find('td:eq(4)').text();
let start = $(this).find('td:eq(5)').text();
let end = $(this).find('td:eq(6)').text();
.......ajax method () etc
................
}
So far, it has been working perfectly and fetching me the correct data. I had another function elsewhere in the page, where clicking on some links would fetch some data from the server and reload the page to display the new data. Everything was working like clockwork.
Now, I decided that when re-displaying fresh data, instead of reloading the page, it's better to refresh the #mytable div. Indeed, it worked, but alas it spoiled the first function. So basically the function below has introduced a bug elsewhere in the page, and I'm not sure why or how to fix it. It's as if the div refresh has completely disabled the event handler. Any ideas?
$(document).ready(function() {
$(".key").click(function(event) {
event.preventDefault();
var word = event.target.innerHTML;
$.ajax({
url: '.../',
data: {
action : "key",
keyword: word
},
type: 'get',
success: function(data){
$('#mytable').load("/.../../..." + ' #ytable');
},
error: function(e){
console.log(e);}
});
});
});
I have a heavily ajax based application wherein i only have a login page and the main page.
Most of my links are "ajaxed" and i have them done like this:
//get the href of the link that has been clicked, ajaxify ANY links
$(document).on('click', '.tree a', function () {
var link = $(this).attr('href'); //get the href off the list
$.ajax({ //ajax request to post the partial View
url: link,
type: 'POST',
cache: false,
success: function (result) {
$('#target').html(result);
$.validator.unobtrusive.parse($("form#ValidateForm"));
}
});
return false; //intercept the link
});
I want to implement "pushState" on my application and the first step that i have done so far is to add this code:
$(document).on('click', 'a', function () {
history.pushState({}, '', $(this).attr("href"));
});
Now it updates my address bar whenever i click on any of my links and the ajax content gets successfully loaded.
I am kinda new to this API so i don't know what am i missing but here are my issues so far:
when i press the "back" button, nothing happens. I read about "popstate" and browsed through SO to look for solutions but i can't
seem to make them work.
When i click the link from the history, i get the "raw" view of the child html w/o the layout from the master html. What do i need to do if i want it to be displayed like
it was clicked from my main application?
Most of my child views are either forms or list.
This code should help you :
function openURL(href){
var link = href; //$(this).attr('href');
$.ajax({
url: link,
type: 'POST',
cache: false,
success: function (result) {
$('#target').html(result);
$.validator.unobtrusive.parse($("form#ValidateForm"));
}
});
window.history.pushState({href: href}, '', href);
}
$(document).ready(function() {
$(document).on('click', 'a', function () {
openURL($(this).attr("href"));
return false; //intercept the link
});
window.addEventListener('popstate', function(e){
if(e.state)
openURL(e.state.href);
});
});
I have a Jquery function to delete a row in an HTML table, it looks like this;
$(document).ready(function(){
$("#thisNet td a.delete").click(function() {
if (confirm("Are you sure you want to delete this row?")) {
var id = $(this).parent().parent().attr('id');
var data = 'id=' + id ;
var parent = $(this).parent().parent();
$.ajax({
type: "POST",
url: "delete-row.php",
data: data,
cache: false,
success: function()
{
parent.fadeOut('slow', function() {$(this).remove();});
}
});
}
});
});
I don't know if it works or not because when I click the button I never get into the function. The delete item to click is in a table created by PHP/MySQL. I followed the tutorial here; https://sarfraznawaz.wordpress.com/2009/09/14/deleting-table-rows-using-jquery-and-php/ to create the delete function. I'm guessing the reason it doesn't fire has to do with timing. The $(document).ready(function() already thinks the page is done loading before the table is created..but I don't know how to overcome this problem.
The page is here; http://kcmecc.org/RaspPi/ once you access it use the drop down to select Net #1. The delete column is the last one with the red x.
Your delete button doesn't exist on document ready. You need to use .on to delegate the event to an ancestor element when dynamically adding elements...
$(document).on('click', '#thisNet td a.delete', function() {
I have a list in HTML which looks like
<a onclick="open_file()" id="3.txt">3.txt</a>
My open_file() function is looking this
function open_file() {
$("a").click(function (event) {
var file_name = event.target.id;
$("#f_name").val(file_name);
$.ajax({
url: "docs/" + file_name,
dataType: "text",
success: function (data) {
$("#text_form").val(data);
$('#text_form').removeAttr('readonly');
$('#delete_button').removeAttr('disabled');
$('#save_button').removeAttr('disabled');
}
})
});
}
The problem is function finally loads data into all fields(text_form and f_name) only after two clicks on such link. It works even if I at first click on one file, then click on another and it loads. Is there any way to fix this?
What you're currently doing is adding an onclick event to a link that calls a function that adds another onclick event via jQuery.
Remove the onclick property and the open_file() function wrapper so that jQuery adds the event as you intended.
You do not need onclick="open_file()" this:
<div id='linkstofiles'>
<a id="3.txt">3.txt</a>
//other links go here
</div>
$("#linkstofiles a").click(function (event) {
var file_name = event.target.id;
$("#f_name").val(file_name);
$.ajax({
url: "docs/" + file_name,
dataType: "text",
success: function (data) {
$("#text_form").val(data);
$('#text_form').removeAttr('readonly');
$('#delete_button').removeAttr('disabled');
$('#save_button').removeAttr('disabled');
}
})
});
You don't need to bind a click event again in the function when you have onclick in your html.
Also for $ is not defined, you need to put jquery library in the head.
I have some java script that work behind a navigation menu, the user clicks the nav button, and some AJAX fires and brings in some HTML, what I want is for if that same link is clicked again then the content that was loaded in by that specific button is removed from the markup.
Does anyone have ideas? My code currently stands at
$("#Blog").click(function (ev) {
ev.preventDefault()
var url = $(this).attr("href");
$.ajax ({
url: "index.php/home/category",
type: "GET",
success : function (html) {
//alert("Success");
$("#accordion").append(html);
}
});
});
Try using .toggle instead of .click:
This would allow you to add a second function which removes the content when the button is clicked again.
$("#Blog").toggle(function (ev) {
ev.preventDefault();
var url = $(this).attr("href");
$.ajax ({
url: "index.php/home/category",
type: "GET",
success : function (html) {
//alert("Success");
$("#accordion").append(html);
}
});
},
function (ev) {
// remove content from accordion here
});
$("#accordion").append(
$("<div class='AJAXContend' />").append(html)
);
And then you can easily do $('.AJAXContend').remove();.
Another option is to do $('#accordion :last-child').remove();, but this is a little hacky.
$("#Blog").click(function (ev) {
ev.preventDefault();
Missing the comma after preventDefault.
So I don't know jQuery enough to answer in that way, but why not use a simple boolean switch?
// Pseudo:
If clicked and the switch is false, show the HTML, and set the Switch to True
If clicked and the switch is true, hide the HTML, and set the Switch to False
That should solve the problem.
The following code is probably horribly wrong, but I will use it to explain my thinking:
//Global Variables
var switch = false;
//Function
if(!switch)
{
$("#Blog").click(function (ev) {
ev.preventDefault()
var url = $(this).attr("href");
$.ajax ({
url: "index.php/home/category",
type: "GET",
success : function (html) {
//alert("Success");
$("#accordion").append(html);
}
});
});
switch = true;
}
else
{
$("#accordion").innerHTML = "";
switch = false;
}
