Javascript - Wait a function to finish
<p>I need to implement a confirm box replacement by using jquery dialog. I have a calling function like this </p>

<pre><code>function callingFunc() {

 var a = confirmJquery("text", 300, 300, "ok", "cancel"); 

 if (a == true) {
   .....
 }
 else {
   .... 
 }
}
</code></pre>

<p>This is the confirmJquery function</p>

<pre><code>function confirmJquery(msg, width, height, txtOk, txtCancel) {

    var div = document.createElement('div');
    div.className = "confirmJquery";

    var span = document.createElement('span');
    $(span).html(msg);
    div.appendChild(span);

    var buttonOk = document.createElement('button');
    buttonOk.className = 'buttonStyleBigger';
    $(buttonOk).html(txtOk);

    var buttonCancel = document.createElement('button');
    buttonCancel.className = 'buttonStyleBigger';
    $(buttonCancel).html(txtCancel);

    var divBottom = document.createElement('div');
    divBottom.className = 'dialogAction';

    divBottom.appendChild(buttonOk);
    divBottom.appendChild(buttonCancel);

    div.appendChild(divBottom);

    var dialog = window.parent.$(div).appendTo(window.parent.document.body);

     // open the dialog
    dialog.dialog({
        height: height,
        width: width,
        resizable: false,
        // add a close listener to prevent adding multiple divs to the document
        close: function(event, ui) {
            // remove div with all data and events
            dialog.remove();
        },
        modal: true
    });

    $(buttonOk).bind('click', function(){
        return true;

    });

    $(buttonCancel).bind('click', function() {

        return false;
    });

}
</code></pre>

<p>The problem is, the confirmJquery function always finish before the button (Ok or Cancel) is pressed; hence, there is no value in the calling function. I need to make the confirmJquery waits until user press the button and then function finish and the rest of the calling function continues. How can i do that ? </p>

<p>I need  to update more details: I already tried the call back function way. It works perfectly. But, life is not easy like that. This is a very big, old, messy system. Doing that requires me to re-write lot lot of functions, so i need to create a function that act exactly like the confirm function of javascript </p>
