how can i make a dialog box from jquery show only after i hit a button?

Question

this code is from the demo of modal confirmation from jquery's site.

<script type="text/javascript">
$(function() {
 $("#dialog").dialog({
  bgiframe: true,
  resizable: false,
  height:140,
  modal: true,
  overlay: {
   backgroundColor: '#000',
   opacity: 0.5
  },
  buttons: {
   'Yes': function() {
    $(this).dialog('close');
   },
   'No': function() {
    $(this).dialog('close');
   }
  }
 });
});
</script>



<div class="demo">

<div id="dialog" title="Empty the recycle bin?">
    <p><span class="ui-icon ui-icon-alert" style="float:left; margin:0 7px 20px 0;"></span>These items will be permanently deleted and cannot be recovered. Are you sure?</p>
</div>

<!-- Sample page content to illustrate the layering of the dialog -->
<div class="hiddenInViewSource" style="padding:20px;">
    <p>Sed vel diam id libero <a href="http://example.com"&gt;rutrum convallis</a>. Donec aliquet leo vel magna. Phasellus rhoncus faucibus ante. Etiam bibendum, enim faucibus aliquet rhoncus, arcu felis ultricies neque, sit amet auctor elit eros a lectus.</p>
    <form>
     <input value="text input" /><br />
     <input type="checkbox" />checkbox<br />
     <input type="radio" />radio<br />
     <select>
      <option>select</option>
     </select><br /><br />
     <textarea>textarea</textarea><br />
    </form>
</div><!-- End sample page content -->

</div><!-- End demo -->

<div class="demo-description">

<p>Confirm an action that may be destructive or important.  Set the <code>modal</code> option to true, and specify primary and secondary user actions with the <code>buttons</code> option.</p>

</div><!-- End demo-description -->

Answer 1

Add the button to the page and add the code to the click event of the button.

<script type="text/javascript">
$(function() {
    $("#button").click(function(){
    $("#dialog").dialog({
            bgiframe: true,
            resizable: false,
            height:140,
            modal: true,
            overlay: {
                    backgroundColor: '#000',
                    opacity: 0.5
            },
            buttons: {
                    'Yes': function() {
                            $(this).dialog('close');
                    },
                    'No': function() {
                            $(this).dialog('close');
                    }
            }
      });
   });
  });
</script>

and in HTML

<input type='button' value="click" id="button"/>

$("#btnTest").click(function() {
       $('#dialog').dialog('open');
        return false;
    })

That should open the dialog you have defined - attaches the dialog open function to click event of button

Oh - and set autoOpen: false on the dialog setup properties :)

Answer 3

Right or wrong, here's an example from a generic alert style dialog that I use:

Set up the dialog (in document ready):

$("#generic-dialog").dialog({
    autoOpen: false,
    buttons: {
        Ok: function() {
            $(this).dialog("close");
        }
    }
});

And open the dialog (after some event):

$("#generic-dialog")
   .text("Status updated successfully.")
   .dialog("option", "title", "Your Status").dialog("open");
