Remove value from input with jQuery

This jQuery code removes the value of a input text type when the user clicks on the input.


$(document).ready(function(){
$(function(){
$('input:text').each(function(){
var inputValue = $(this).val();
$(this).focus(function(){
$(this).val('')
});
$(this).blur(function(){
if($(this).val() == ""){
$(this).val(inputValue);
}
});
});
});
});

getElementsByClassName function

Since there doesn’t exist something like a getElementByClassName function, I just tried the js prototype library which has a getElementsByClassName function. You can download it here.

Include it in the head like this:

Then use it like this:

var test = document.getElementsByClassName("test");

the variable test will be an array.
