Visualforce: Pass javascript variable to controller

Question

I want to pass a javascript variable into the controller of my visualforce page. Using <apex:param value="JAVASCRIPTVARIABLE" /> is throwing me an error because it expects JAVASCRIPTVARIABLE to be an exposed property of the controller. Please tell me how to pass the value of JAVASCRIPTVARIABLE to a variable in the controller. Thanks in advance.

you can achieve this by using actionFunction.. What have you tried so far? — DOMINIC EDWARD, Feb 11 '16 at 07:43

Here is a SFSE link which talks about how to pass javascript values to controller. It explains how to use <apex:param also. Hope this helps.

Snippets

<!-- A new value will be set to the apex:param -->
<apex:actionFunction name="passStringToController" action="{!myMethod}" rerender="myHiddenField">
    <apex:param name="p1" value="" assignTo="{!myString}" />
</apex:actionFunction>

<!-- Here we can directly access the action function per name and assign a variable value -->
<apex:commandButton value="Test me" onclick="passStringToController('new value'); return false;" />
