Js and Radiobutton

[mhmda]

When I change the value of radiobutton using js, according to the alert messages it changed but visually on the page it still the old value:

I try it in IE8 and Firefox 3.5.7, in firefox I got the 2 alerts,but in IE I got only ONE alert,the first one and then the page refreshs.

function Button1JSClick($sender, $params)
{
?>
alert(document.getElementById("RadioButton1").valu e);
document.getElementById("RadioButton1").value="toy ou";
alert(document.getElementById("RadioButton1").valu e);
return false;
<?php
}

the second alert is: toyou, but on the page nothing changes...

and btw I tried to use 405hp vcl$ function (I copy it to my common.js) but it didn't work, I don't know why...

When stuff like that happens you just need to look into the browsers source to see how they built the object.

For whatever reason they used RadioButton1_caption as the id.
So
RadioButton1_caption.innerHTML="toyou";
does what you want.

When you change common.js you need to refresh your cache as external js files are not downloaded all of the time. When I do something to them I actually modify my vcl to change the name in order to force downloads by my users.

I appreciate your effort for helping...
sometimes my question seems to be a basic thing in web world that I should be familiar with.
But this is my first time with web...

findObj('RadioButton1_caption').innerHTML="yes!!!! !!!!!!!!!!!!1";

Did the work for changing the caption of radio button.

I have another question:
in some sites they use js to fill some forms or fields when I did refresh (F5) in the browser the information still there. and in other sites you have to fill again.

How can I do that (to maintain the information even in case the user refresh the page)?

AFAIK
In scripts that use the vcl you either have to store it in session (php with or without ajax) or with js keep them in cookies on the users machine and have the onload event load them.

Hello,
how can i set radiogroup or radiobutton using JS?

Its doesn't work:
findObj("RadioButton1").checked=true;
findObj("RadioGroup1_1").checked=true;

[405hp]

Those work for me - or are you not having them set back at the server?

Thank you for your prompt response.
My problem is caused by something else.
Still looking...

Delphi4php is a very, very good program.
