Question

JQuery Dialog, Passing a variable from link to javascript

Asked by: beigs

I an running jQuery on a application and am struggling a little bit with passing a variable from the link that opens a modal-dialog into javascript.  Example, I have a page that lists user accounts.  Next to each user account, I have a "delete" icon.  When the user clicks the icon, I have a modal box that opens for confirmation.  Once the user confirms the delete, I'm using AJAX/POST to send the information to a php file.

The first problem I ran into was getting the jQuery script to run the same modal box multiple times because the '<a id=' was always the same.  I fixed this by changing the id in the array to 'delete-user-$USERNAME' and then using $("a[id^='delete-user']").click(function() to open the dialog no matter which icon was clicked.  

The problem I am running into now is extracting that username in javascript to pass it to the ".ajax/data: " variable.

Please note that I added the 'if (deleteUser != "")' for debugging purposes.

I know this should be simple, but my brain is fried from looking at it so long and I just can't see the solution.  Any help would be appreciated.

<a href="#" id="delete-user-<?php echo $uary['username']; ?>" title="Delete User" style="display: inline-block; width: 16px; height: 16px;" class="ui-state-default ui-corner-all ui-widget ui-helper-clearfix ui-icon ui-icon-trash"></a>	
 
then in jquery...
 
jQuery(document).ready( function(){ 
		
		var fullID = $("a").attr("id"),
			deleteUser=fullID.replace(/delete-user-/,"");
		
		$("#remove_user").dialog({
			bgiframe: true,
			autoOpen: false,
			modal: true,
			buttons: {
				'Delete Account': function() {
					
					if (deleteUser != "") {
						$.ajax({
							type: "POST",
							url: "func/remove_user.php",
							data: "username=" + deleteUser
						});
						$(this).dialog('close');
						window.location = "userManagement.php";
					} else {
						alert("No Data Detected");
					}
				},
				Cancel: function() {
					$(this).dialog('close');
				}
			},
		});
		
		$("a[id^='delete-user']").click(function() {
			$('#remove_user').dialog('open');
		})
 
	});

Thanks for your help.  I finally realized that my problem was that the following code was wrong.
'var fullID = $("a").attr("id"),
deleteUser=fullID.replace(/delete-user-/,"");

Rather than pull the div ID from the clicked icon, it was pulling the div ID of the modal box.  Once I realized that I had to get the ID from the clicked icon first, it snapped together pretty quickly.  The updated, correct code is below (where deleteUser is replaced with rUser).

Thanks for your help..

jQuery(document).ready( function(){ 
 
	$("a[id^='delete-user']").click(function() {
		dUser = $(this).attr('id');
		rUser = dUser.replace(/delete-user-/,"");
		return rUser
	});
	
	$("#remove_user").dialog({
		bgiframe: true,
		autoOpen: false,
		modal: true,
		buttons: {
			'Delete Account': function(){
					
				if (rUser != "") {
					$.ajax({
						type: "POST",
						url: "func/remove_user.php",
						data: "username="+rUser
					});
					$(this).dialog('close');
					window.location = "userManagement.php";
				} else {
					alert("No Username Detected");
				}
			},
			Cancel: function(){
				$(this).dialog('close');
			}
		},
	});
	
	$("a[id^='delete-user']").click(function(){
		$('#remove_user').dialog('open');
	})
});
