checkbox check using javascript..

[jagprg]

hi,

I am using <html:checkbox....tag for my checkbox, I get the value of it true or false from a Object dynamically..shown below

<html:checkbox property="trafficSignals" disabled="false" value='<%= home.getTrafficSignals() ? "true" : "false" %>'/>&nbsp;&nbsp;Traffic Signals<br/>

I am able to set its value as true or false, but not able to show it on the jsp as checked, Could anyone tell how I can show it as checked using javascript.

thanks in advance.

Hi!

document.forms['formname'].elements['checkboxname'].checked = true;

or

document.forms['formname'].elements['checkboxname'].checked = false;

Cheers!

Do you really want to set the VALUE of the checkbox depending on the value of that variable?

It seems to me you should be leaving the value alone (set at "true") and setting whether or not the checkbox is checked depending on the value of that variable.

For that you don't need any javascript, just do it in you server-side code like this:

<html:checkbox property="trafficSignals" disabled="false" value='true' <%= home.getTrafficSignals() ? "checked" : "" %>'/>&nbsp;&nbsp;Traffic Signals<br/>

Hi Tracy,
I tried that but, the check box disappeared next to the text(I could see only the text but not checkbox). So, I decided to use javascript.
