need value from function in textbox

[priyankadeven]

How do I get a value in a textbox after clicking a submit button that calls function that returns that value...?

Shld I say onSubmit=return validate() ie. call function

or Shld I say onChange=return validate() of textbox?

the onSubmit event is trigered from the <form> tag. that is the only tag that is is valid for. The onChange event can be used wth most (I think all) form objects.

to pass a parameter like the value entered in the textbox you state within the () of the event what to pass to the function. then recieve it again within the () of the function
eg:
<input type=&quot;text&quot; onBlur=&quot;callSomething(this.value)&quot;>
this.value is the same as saying
document.formname.textname.value
then recieve it as a varaible
function callSomething(str)
str = the value passed from the textbox
this defined from devguru.com

The keyword this is used to refer to the current object. In a method, it usually refers to the calling object. In the following example the code first creates a function DescribeAge that takes as its parameter an object, and returns one of two text values depending on the value of that same object's Year property. Then another object called Car is created whose third property Description is the value returned by the DescribeAge function. The keyword this is used as the parameter of the DescribeAge function to refer to whichever object is calling it, as seen in the final bit of code which creates a specific instance of the Car object whose Description property will now contain the string &quot;Old-fashioned&quot;:
