you can write up a directive for your UI slider, it works something like this:

<pre><code>&lt;input type="text" ng-model="setMin" /&gt;
&lt;input type="text" ng-model="setMax" /&gt;
&lt;slider min="setMin" max="setMax"&gt;&lt;/slider&gt;
</code></pre>

and your directive would be something like this:

<pre><code>app.directive("slider", function() {
 return {
 restrict: "AE",
 scope:{
 min:"=",
 max:"="
 },
 link: function(scope, ele, attrs) {

 ele.slider({
 min: scope.min,
 max: scope.max,
 range: "min",
 value: "5",
 slide: function(event, ui) {
 scope.$apply(function() {
 //update on the view using ui.value;
 //scope.number = = ui.value;
 });
 }
 });

 // You can watch the value min,max and then reapply your UI slider 
 scope.$watch('setMin', function(newValue, oldValue) {
 if (newValue !== null &amp;&amp; newValue !== undefined) {
 // re-apply UI slider
 }
 }, true);

 scope.$watch('setMax', function(newValue, oldValue) {
 if (newValue !== null &amp;&amp; newValue !== undefined) {
 // re-apply UI slider
 }
 }, true);

 }
 }
});
</code></pre>

Here is a solution that works. Thank you to Duc Hong - his answer was instrumental in helping me to figure this out. Please let me know if there is a better way to do this.

<pre><code>app.directive('slider', function() {
 return {
 restrict: 'AE',
 link: function(scope, element, attrs) {
 element.slider({
 value: scope[attrs.ngModel],
 min: parseInt(attrs.min),
 max: parseInt(attrs.max),
 step: parseFloat(attrs.step),
 slide: function(event, ui) {
 scope.$apply(function() {
 scope[attrs.ngModel] = ui.value;
 });
 }
 });
 }
 };
});
</code></pre>

A small improvement over the Rodney's solution:

<pre><code>app.directive('slider', function() {
 return {
 restrict: 'AE',
 link: function(scope, element, attrs) {
 element.slider({
 value: scope[attrs.ngModel],
 min: parseInt(attrs.min),
 max: parseInt(attrs.max),
 step: parseFloat(attrs.step),
 slide: function(event, ui) { 
 scope.$apply(function() { 
 scope[attrs.ngModel] = ui.value;
 });
 }
 });

 scope.$watch(attrs.ngModel, function(newVal, oldVal){
 element.slider({value: newVal});
 });
 } 
 };
});
</code></pre>

It allows to detect and update the slider position if the model changes. 

If your model contains dots (for instance, <code>ngmodel = "Configuration.Size"</code>), <code>scope[attrs.ngModel]</code> no longer works. A workaround is to use <code>_.get</code> and <code>_.set</code> from <code>lodash</code> library instead.

I'm trying to build an Angular directive that creates a keyboard-accessible slider widget. I found several Angular sliders on Github, but none of them are keyboard-accessible. So, I'm trying to convert the jQuery UI slider to an Angular directive.

Here is how I'd build the widget without Angular.

HTML:

<pre><code>&lt;div id="slider"&gt;&lt;/slider&gt;
&lt;input type="text" id="amount"/&gt;
</code></pre>

Javascript:

<pre><code>$("#slider").slider({
 min: 1,
 max: 10,
 slide: function(event, ui) {
 $("#amount").val(ui.value);
 }
});
</code></pre>

And this is how I'd like the Angular directive to work:

<pre><code>&lt;slider min="1" max="10" ng-model="sliderValue"/&gt;
&lt;input type="text" ng-model="sliderValue"/&gt;
</code></pre>

As an example, here is a jsFiddle that shows how someone converted a jQuery UI date widget to an Angular directive.

<a href="http://jsfiddle.net/xB6c2/121/" rel="nofollow">http://jsfiddle.net/xB6c2/121/</a>

I'd like to do something similar to this for the slider widget. Thanks!
