jQuery Store Data in a Div

jQuery code snippet to store data in a div for reference later. The data is not shown in the div but is stored against the element. Note that if the jQuery collection references multiple elements, the value returned refers to the first element.

Here is how you do it.

//set the value to be stored
$("div").data("valuename", "hello");

//get the stored value
var value = $("div").data("valuename");
//outputs "hello"
alert(value);

//you can also change the value
$("div").data("valuename", 101);

//get the new stored value
var value = $("div").data("valuename");
//outputs "101"
alert(value);

You can use removeData(valuename) to remove the data item stored in the div.
