how we use a variable within and object name?
for example if i want to get the value of an input box:
var x = document.theform.variable.value
where variable is an input field in the form

The easiest way is to name your input field.For example, you have this in your page:

Code: Select all

<form name="myform" action="#" method="post">
<input type="text" name="myinput">
<input type="button" onclick="show()" value="Show Input Value">
</form>


If you want to get the value of the input box, it is as easy as:

Code: Select all

function show()
{
var accept = document.myform.myinput.value
alert ('Did you key in '+accept +' right?');
}


Hope made sense
