return onclick value to a JavaScript function

rated 0 times [ 13] [ 5] / answers: 1 / hits: 29904 / 12 Years ago, sat, april 7, 2012, 12:00:00

I have created an anchor with an onclick event which calls a JavaScript function. The JavaScript function returns some value. I want to use that value in another JS function.

e.g
loading() will return some value which will get passed to another js function. How do I capture and store the return value, and then pass this value to that function?

Can you simply call the outer function with the inner function?

function outerFunc(a)

{

  alert(a);

}



function innerFunc()

{

  return 'test';

}



onclick=outerFunc(innerFunc());

Or, if you need to use the return value in another event, set a variable.

var retval;

function outerFunc()

{

  if(retval) alert(retval);

}



function innerFunc()

{

  retval = 'test';

  return retval;

}



onclick=return innerFunc();

In someother onclick event

onclick=return outerFunc();
