The easiest way is to name your input field.For example, you have this in your page:
| Code: |
<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: |
function show()
{
var accept = document.myform.myinput.value
alert ('Did you key in '+accept +' right?');
}
|
Hope made sense  |
