  1. POintegrating jquery ui dialog with knockoutjs
    text
    copied!<p>I am trying to create knockoutjs bindings for jquery ui dialogs, and cannot get the dialog to open. The dialog element is created correctly, but seems to have <code>display: none</code> that calling <code>dialog('open')</code> doesn't remove. Also, the call to <code>dialog('isOpen')</code> returns the dialog object rather than a boolean.</p> <p>I am using the latest knockoutjs and jquery 1.4.4 with jquery ui 1.8.7. I've also tried it with jQuery 1.7.1 with the same results. Here's my HTML:</p> <pre><code>&lt;h1 class="header" data-bind="text: label"&gt;&lt;/h1&gt; &lt;div id="dialog" data-bind="dialog: {autoOpen: false, title: 'Dialog test'}"&gt;foo dialog&lt;/div&gt; &lt;div&gt; &lt;button id="openbutton" data-bind="dialogcmd: {id: 'dialog'}" &gt;Open&lt;/button&gt; &lt;button id="openbutton" data-bind="dialogcmd: {id: 'dialog', cmd: 'close'}" &gt;Close&lt;/button&gt; &lt;/div&gt; </code></pre> <p>and this is the javascript:</p> <pre><code>var jQueryWidget = function(element, valueAccessor, name, constructor) { var options = ko.utils.unwrapObservable(valueAccessor()); var $element = $(element); var $widget = $element.data(name) || constructor($element, options); $element.data(name, $widget); }; ko.bindingHandlers.dialog = { init: function(element, valueAccessor, allBindingsAccessor, viewModel) { jQueryWidget(element, valueAccessor, 'dialog', function($element, options) { console.log("Creating dialog on " + $element); return $element.dialog(options); }); } }; ko.bindingHandlers.dialogcmd = { init: function(element, valueAccessor, allBindingsAccessor, viewModel) { $(element).button().click(function() { var options = ko.utils.unwrapObservable(valueAccessor()); var $dialog = $('#' + options.id).data('dialog'); var isOpen = $dialog.dialog('isOpen'); console.log("Before command dialog is open: " + isOpen); $dialog.dialog(options.cmd || 'open'); return false; }); } }; var viewModel = { label: ko.observable('dialog test') }; ko.applyBindings(viewModel); </code></pre> <p>I have set up a <a href="http://jsfiddle.net/gene/BzKHj/" rel="noreferrer">JSFiddle</a> that reproduces the problem. </p> <p>I am wondering if this has something to do with knockoutjs and event handling. I tried returning <code>true</code> from the click handler, but that did not appear to affect anything.</p>
