Javascript variable to form action?

Copy linkTweet thisAlerts:
Mar 20.2009

Hey guys,
I’m having a little difficulty in finding a way to put the contents of a javascript variable into the action section of a form. Either puting it in or writing it there idk. If I have to write to that section, then how can I do it without taking out what’s already in the field?

@ZeroKilledMar 20.2009 — a bit confusing to me. you meant if there is a value in the action attribute, how you would set another value without clearing the actual? if so, you need a reference to the form and then read the action property. then you would append the new content with the actual value:
<i>
</i>myform = document.forms[0];
// assuming forms[0] is the form;
var myvar = 'whatever is the new content';
// obviously, should be a string;
myform.action = myform.action + myvar;

Success!
