jQuery在Wordpress中不起作用-默认工作

Question

This little snippet here works just fine in JSFiddle, but it does nothing when I put it in with the tabs within a PHP file for a WordPress button. I currently have standard JavaScript on it to open a popup dialog with "Ok" & "Cancel" but I'd like to use "Yes", "No" & "Cancel" instead.

What's the issue here?

HTML

<li class="level3 item578"><a id="btnOpenDialog" value="Confirm Dialog Box" href="#"><span>ArmA 2</span></a>

</li>
<div id="dialog-confirm"></div>

jQuery

function fnOpenNormalDialog() {
$("#dialog-confirm").html("Do you have Play WithSix installed?");
// Define the Dialog and its properties.
$("#dialog-confirm").dialog({
    resizable: false,
    modal: true,
    title: "ArmA 2",
    height: 250,
    width: 360,
    buttons: {
        "Yes": function () {
            $(this).dialog('close');
            window.location.href = "http://www.fogamers.com/arma2.php";
        },
            "No": function () {
            $(this).dialog('close');
            window.open('http://play.withsix.com/', '_blank');
        },
            "Cancel": function () {
            $(this).dialog('close');
        }
    }
});

}
$('#btnOpenDialog').click(fnOpenNormalDialog);

Answer 1

What cpilko said is valid, but if you prefer to use the $ variable in your code (it can be easier for multiple reasons) then redefine it when you call your jquery like so:

<script>
 jQuery(document).ready(function($) {

  // you can now use the $ variable
  $("#dialog-confirm").html("Do you have Play WithSix installed?");

 )};

</script>

Answer 2

Wordpress uses jQuery noconflict mode . Try replacing all the $ in your code with jQuery .

function fnOpenNormalDialog() {
  jQuery("#dialog-confirm").html("Do you have Play WithSix installed?");
  ...
