Question: I have a drop down list.
In Jquery what is the event I would use when the user makes a selection.

The id of the dropdown is drp1

I tried the following but did not work:

```
$("#ddrp1").SelectChanged(SelectionItem);

```

Answer: 
Use the [`change()`](http://api.jquery.com/change/) event:

```
$("#ddrp1").change(function() {
    // Pure JS
    var selectedVal = this.value;
    var selectedText = this.options[this.selectedIndex].text;

    // jQuery
    var selectedVal = $(this).find(':selected').val();
    var selectedText = $(this).find(':selected').text();
});

```

In jQuery 1.7, you can use [`.on()`](http://api.jquery.com/on/)

```
$("#ddrp1").on("change", function() {
    // Pure JS
    var selectedVal = this.value;
    var selectedText = this.options[this.selectedIndex].text;

    // jQuery
    var selectedVal = $(this).find(':selected').val();
    var selectedText = $(this).find(':selected').text();
}​​​​);​

```

Here's [a working jsFiddle](http://jsfiddle.net/JamesHill/LwwFL/) using `on()`
What you want is `onchange` event which can be written as

```
 $("#ddrp1").change (function () { 
 });

```
