Passing loop data as variable from JavaScript to AJAX via Bootstrap modal

My code below was used to retrieve records from a loop using JavaScript. Everything works fine. Each of the records button has a unique id that when click
should alert users_id in a Bootstrap Modal popup.
The problem is that the looped button that contains users_id is not alerting anything when each button is clicked.
Below is the code for retrieving records in JavaScript along with Bootstrap modal button:
<script>
$(document).ready(function () {
$.post('users.php', function(response){
$.each(JSON.parse(response).items, function(i,v) {
$('.userslist').append('<span>'+v.id+'</span> Profile');
});
});
});
</script>
Below is the code for posting the users_id and then alert it:
<script>
$(document).ready(function(){
$(".modalLink").click(function() {
var id = $(this).attr("id");
alert(id);
var dataString = 'id='+ id;
$.ajax({
type: "POST",
url: "ajax_modal.php",
data: dataString,
cache: false,
success: function(data) {
$("#rmm").html(data);
}
});
});
});
</script>
but if I take the Modal button outside the retrieve records in a javascript loop
it will alert users_id and everything will work fine as in code below
Profile
Can someone help me make each of the JavaScript looped button to post its own unique users_id and then alert it in a Bootstrap modal popup. I have attached a screen shot of the result obtained from the JavaScript loop.
Thanks

If I understand your question properly;
Try changing
$(".modalLink").click(function() {
to
$(document).on('click', '.modalLink', function() {
Without seeing the rest of your code or a working fiddle, I suspect your content is dynamic and JQ cannot bind the click handler, simply because there is no content to bind to. this answer does a good job of explaining the difference between .on and .click.
If you get the expected result, I would drop the document selector and use the closest parent static element.

Having issues calling an ID after I have appended data from an ajax call

Ok,
So I have a .on click event which is called to an ajaxed script. The script returns a set of HTML information.
Now, what I seem to be having an issue with and maybe I am just not typing the right search terms in for this so my apologies if this was answered already.
When the html is appended to the correct box, the user is then able to click a link on that box, drop down the box and see a new input box. The user should be able to type the text in and hit the enter key and it should work.
When I run an inspect element, I do see the element's ID properly inserted, but it is like javascript doesn't even recognize the new element id.
UPDATE: I am really not sure why you need code to be able to answer this question, however here it is. The code works normally unless the above happens so yes I am appending it, and yes I am SURE i am appending it, please make sure to read everything before posting a comment, thanks!
$('body').on('keypress', '.peapComment', function(event) {
if(event.which == 13) {
var peap_id = $(this).attr('rel');
var comment = $(this).val();
$.ajax({
type: "POST",
url: "index.php",
data: {
page: "postPeapComment",
peap_id: peap_id,
comment: comment,
}
}).done(function(msg) {
console.log(msg);
$('#comment_' + peap_id).append(msg);
});
console.log('Send to Peap #' + peap_id + ': ' + comment);
$('#commentbox_' + peap_id).val('');
}
});

I have tested your code, and it seems to work without problems for me. My assumption would be that the data returned from your ajax call, is failing to return the proper "Peap_ID" or not returning anything all around, as this is the only way I can reproduce what you have claimed your error is, otherwise the code you have posted looks great.

jQuery click event interrupts setInterval

I'm creating script where I use AJAX from jQuery. I've got a problem, as on my website I've got hidden object. Moreover I use setInterval to frequently refresh a piece of my script. Everything works well, but until I click on link to set this hidden object to be visible. When I click on link and make object visible, setInterval stops refreshing page. This is my code to AJAX:
$(document).ready(setInterval(function() {
$.ajax({
type: "POST",
url: "score.php",
success: function(html){
$("#loadplace").hide().show().html(html);
}
});
return false;}, 60000));
and this is code for link:
$('div#bar a#squad1').click(function(e) {
e.preventDefault();
$('div#s1 table.events1').hide();
$('div#s1 table.index_players1').fadeIn();
});
$('div#bar a#events1').click(function(e) {
e.preventDefault();
$('div#s1 table.index_players1').hide();
$('div#s1 table.events1').fadeIn();
});
is there any solution in jQuery for my problem ?
P.S. I hope you understand what I wrote, I know that my English is not so good as I wish it to be.

Ajax calls within nested divs not working for FireFox with MVC3

I have a cshtml page that has a link, and a div to display some content.
<a href="#" onclick="Show_New_Page('#First_Div')>My Link</a>
<div id="First_Div">
#Html.Partial("General_Page") <- This is the default page that gets displayed on load.
</div>
When you click on the link, the javascript function Show_New_Page gets called and the string '#First_Div' gets passed as a parameter. I pass the name of the div I wish for the ajax in Show_New_Page to put its success value. That function looks like this:
function Show_New_Page(div) {
$.ajax(
{
type: "POST",
url: url, //Declared above globally, unimportant
data: data, //Declared above globally, unimportant
success: function (result) {
$(div).html(result);
}
});
}
When you click on this link in Internet Explorer, the new page gets displayed fine with no issues. However, when you click on this link in FireFox, the entire page turns white and never successfully loads.
There are plenty of posts about issues with Ajax and different browsers, but I was unable to see one that helped me. Any hints or tips I can try are much appreciated. I am very unsure of why this is happening, so if I have left out any information I will certainly do my best to provide it.

There seems to be a missing closing ) when you are calling the Show_New_Page function. Also it's recommended to return false from click handlers to cancel default action:
My Link
Also you might prefer to give this anchor an id:
My Link
and then unobtrusively AJAXify it in a separate file to avoid mixing markup with javascript:
$(function() {
$('#myLink').click(function() {
$.ajax({
type: 'POST',
url: url, //Declared above globally, unimportant
data: data, //Declared above globally, unimportant
context: { id: $(this).data('id') },
success: function (result) {
$(this.id).html(result);
}
});
return false;
});
});

The issue here was the fact that my ajax views that were being passed down after clicking on a link were using document.write() statements. I have learned that this is strange to do after the page has already loaded. I've moved these statements up to the files that were not being loaded with ajax, and that fixed the problem. Thank you to everyone who commented and suggested ideas to me. It was the investigation of these ideas that lead me to the core issue!
The lesson: be careful with excessive document.write() statements in firefox!

Help me make a jquery AJAXed divs' links work like an iframe

I want to make a few divs on the same page work similar to iframes. Each will load a URL which contains links. When you click on those links I want an AJAX request to go out and replace the div's html with new html from the page of the clicked link. It will be very similar to surfing a page inside an iframe.
Here is my code to initially load the divs (this code works):
onload:
$.ajax({
url: "http://www.foo.com/videos.php",
cache: false,
success: function(html){
$("#HowToVideos").replaceWith(html);
}
});
$.ajax({
url: "http://www.foo.com/projects.php",
cache: false,
success: function(html){
$("#HowToProjects").replaceWith(html);
}
});
This is a sample of code that I'm not quite sure how to implement but explains the concept. Could I get some help with some selectors(surround in ?'s) and or let me know what is the correct way of doing this? I also want to display a loading icon, which I need to know where the right place to place the function is.
$(".ajaxarea a").click(function(){
var linksURL = this.href; //
var ParentingAjaxArea = $(this).closest(".ajaxarea");;
$.ajax({
url: linksURL,
cache: false,
success: function(html){
$(ParentingAjaxArea).replaceWith(html);
}
});
return false;
});
$(".ajaxarea").ajaxStart(function(){
// show loading icon
});

Assuming you want to listen to click events for all anchor tags inside all elements with class ajaxarea, then your selector works fine:
$(".ajaxarea a").click(function(){ .. });
And this line of code, while not a selector (you're just accessing a property on the DOM element that was clicked), should work fine as well:
var linksUrl = this.href;
As for ParentingAjaxArea, you'll need to use $(this).closest() with a selector to determine which parent you want, but it's hard to give a specific example without knowing your HTML structure. It looks like you want ParentingAjaxArea to be either the element with id #HowToProjects or #HowToVideos, so you could write:
var ParentingAjaxArea = $(this).closest("#HowToProjects, #HowToVideos");
As for the loading dialog, I think this answer explains a good method (using ajaxStart and ajaxStop).
Edit: I also noticed you're using the click event--If you plan on being able to attach event handlers to links that will be inserted into the DOM via AJAX later, look at delegate or live.

$(".ajaxarea a").live('click',function(e){
e.preventDefault(); //*
var URL = $(this).attr('href');
var parentFrame = $(this).parent(".ajaxarea"); //**
$.ajax({
url: URL,
cache: false,
success: function(html){
parentFrame.replaceWith(html); //***
}
});
});
* - added preventDefault to prevent click action (see e in function's arguments)
** - instead of closest, i used parent – like it more for it's descriptive qualities
*** - the var containing parent AJAX frame should be jQuery object, no need to wrap it in $(..)
This should work fine, but beware, it's untested.
edit:
You probably need a live (okay, I'm sure you need it). what click() does it's that it adds to all elements at the time in DOM an onClick event. What live() does, it's that it waits for any change in DOM and runs used selector (.ajaxarea a) again and if it fits for any of new elements, it adds the action. In pseudocode, it does basically this:
DOM.hasChanged{
$('selector').click(..)
}

I used this example for my own web page:
http://www.queness.com/post/328/a-simple-ajax-driven-website-with-jqueryphp
It works quite well and uses hash tags and jQuery.history.js for the history of your browser. It works very nice, because you can let something like a media player just continue playing. Take a look at my own site elsewise, where you can find the javascript file: ajaxpages.js. I haven't used live(), but maybe I should.

Figured it out! The problem was I was using the function ".replacewith()" which was removing my AJAXed div(class="ajaxarea") entirely instead of replacing the content. The proper function to use here was ".html()".
Here is my working code to make an AJAXed div work like an iframe:
//onload to initialize the div
$.ajax({
url: "http://www.foo.com/projects.php",
cache: false,
success: function(html){
$('#HowToProjects').html(html);
}
});
$(".ajaxarea a").live('click',function(e){ // must use live instead of .click()
e.preventDefault();
var URL = $(this).attr('href');
var parentFrame = $(this).closest(".ajaxarea");
$.ajax({
url: URL,
cache: false,
success: function(html){
parentFrame.html(html);
}
});
});
