Setting session variable - Onclick 3

[MC77]

I have a session variable defined in the application.cfm:

<cflock name="sLogin_Lock" timeout="30" type="exclusive" >
<cfset session.TreeView = 'true'>
</cflock>

In a subsequent .cfm I have a checkbox that has checked/value of the session variable.

<cfinput type="checkbox" name="treeShow" checked="#session.TreeView#"
value="#session.TreeView#" label="Show Applications Window"
onClick="#session.TreeView# = treeShow.selected;"/>

When clicked I want to set the session variable to be equal to treeShow.selected value, but this does not work and errors with "Left side of assignment operator must be variable or property"

I have tried a few variations of using # , etc....any assistance would be greatly appreciated.

what does the resulting html look like from the browser / view source?

i dont use cfform or cfinput at all but unless i am very mistaken about CFFORM, this will not work:

onClick="#session.TreeView# = treeShow.selected;"/>

how exactly is the page going to edit that session variable after coldfusion has finished processing the page? cfform writes a standard html form and the javascript for any validation etc.. that you put into the CFINPUT tags. you would need to put a javascript function call in that onclick attribute to do what you need. use a javascript function to call a hidden iframe or something that can change that session variable.

I was sure that's whats going on, but wanted to see his output to check it out.


the classic client side / server side issue.

You'd have to reload the page (so CF can re-process it) if you want that onClick to register the onlick. Which might be very annoying to the user.
