Javascript Buttons

Question

Is it possible to set a button's onclick action to a javascript variable? The idea is that we are controlling a table with javascript. Whenever one clicks on a row of that table, we update a javascript variable. That var would be the _GET var for the php script to be run.

Answer 1

Add this to the element you want to be clickable :

onclick="setAVariable()"

And then add this javascript function in a php file :

function setAVariable(){ 
 //dostuff 
 var get = "<?php echo _GET ?>" ;
}

Answer 2

myTr.onclick = function () {
 // Make sure you have a keyboard focusable and a non-JS alternative!
 document.forms.myform.elements.myhiddeninput.value = someValue;
}
