Re: [OT]Problem with accessing form Element using javaScript

[Legolas Woodland]

Hi thank you for reply. forceId is just for myfaces , and for now i am not using myfaces. I change that to what you said and i still get the same error from _javascript_ Console Error: staticText8 has no properties Source File: http://localhost:28081/pluto/portal/Publisher/....... Line: 306 Thank you for the help Gerald Müllan wrote: Hi, stupid thing, but try it out with: var testValue = document.getElementById("form1:statictext8"); testvalue.style = "..."; I am more or less sure that this is the problem. In js you can not concat method calls in every case. Apart from that, getting the dom element through the generated id is not best practice. Use forceId="true" in the jsp tag to be sure that you can get the id on client in a predictable manner. cheers, Gerald On 3/31/06, Legolas Woodland <[EMAIL PROTECTED]> wrote: Hi thank you for reading my post.
