# jQuery.removeData()

Categories: Data | Utilities

## jQuery.removeData( element [, name] ) Returns: jQuery

Description: Remove a previously-stored piece of data.

- #### version added: 1.2.3jQuery.removeData( element [, name] )

  elementA DOM element from which to remove data.

  nameA string naming the piece of data to remove.

Note: This is a low-level method, you should probably use `.removeData()` instead.

The `jQuery.removeData()` method allows us to remove values that were previously set using `jQuery.data()`. When called with the name of a key, `jQuery.removeData()` deletes that particular value; when called with no arguments, all values are removed.

### Example:

#### Set a data store for 2 names then remove one of them.

    <!DOCTYPE html>
    <html>
    <head>
      <style>
    		div { margin:2px; color:blue; }
    		span { color:red; }
    		</style>
      <script src="http://code.jquery.com/jquery-1.7rc2.js"></script>
    </head>
    <body>
      <div>value1 before creation: <span></span></div>
    		<div>value1 after creation: <span></span></div>
    		<div>value1 after removal: <span></span></div>
    		<div>value2 after removal: <span></span></div>
    <script>
    var div = $("div")[0];
    $("span:eq(0)").text("" + $("div").data("test1"));
    jQuery.data(div, "test1", "VALUE-1");
    jQuery.data(div, "test2", "VALUE-2");
    $("span:eq(1)").text("" + jQuery.data(div, "test1"));
    jQuery.removeData(div, "test1");
    $("span:eq(2)").text("" + jQuery.data(div, "test1"));
    $("span:eq(3)").text("" + jQuery.data(div, "test2"));</script>

    </body>
    </html>
