I have an html\_area which I use as an API.
It runs fine however I want to retrieve a value calculated within the client side script, can this be done ?
For example :
```auto
html += globals.glbl_ID+'=data.id;'
```
I’d like to display on my servoy form the value in the global variable globals.glbl\_ID

If you are looking for a way to evaluate JavaScript in the browser of a Web client, have a look at the Web Client Utils plugin, on ServoyForge, of course:

Not sure I’ve understood how to use the webclientutils ![:(]( "Sad")
Basically I want to get the value of whatever is in the data.id so I was assuming the variable callback would contain this however it contains a load of scripting.
In other words if data.id was 3 then I want the number 3 returned within Servoy.
```auto
markup += 'var id=data.id;'
var callback = plugins.WebClientUtils.addCallback(getID,['id']);
markup += 'function getID(id) {'+callback+'}'
...
function getid(id) {
application.output(id)
}
```

Ok, I’ve reread whatever documentation I could find and tried various other options includign the following simple test solution which only has a html\_area field defined with the data provider as globals.html.
I’d expect the the getid method to be called but it is not invoked … Sorry but I really have no idea how to get this to work.
```auto
function onLoad() {
var cb = plugins.WebClientUtils.addCallback(getid, ['id']);
var js = 'var id=100;my(id);function my(id){'+cb+'}';
globals.html = ''
}
function getid(){
// I expect id to contain the value 100 but this method is never called
var id = arguments[0];
application ('do I get called ????')
application.output(id)
}
```

Just tried it here, and this works for me.
What OS/Browser do you use?

Am running a web client on developer (v5.21) through Vista and tried it with both Firefox and IE 7.
I also just slightly modified the sample code by adding the alert, I get the alert displayed but the method is not called (no application.ouitput debug info).
```auto
var jsToExecute = "alert('help');var sum = 1 + 2";
plugins.WebClientUtils.executeClientSideJS(jsToExecute, getid, ['sum'])
}
/**
* @properties={typeid:24,uuid:"17B737FE-3A5B-47F3-AA0B-9A4AD1AEAE12"}
*/
function getid(){
// I expect id to contain the value 100 but this method is never called
var id = arguments[0];
application ('do I get called ????')
application.output(id)
}
```

Hum, yes. I tested on Win 7. Will give it a go on Vista but that’s very strange that there would be any differences.
What Servoy version do you use on 7?

same version both running 5.2.1.
Just even did a reinstall oif 5.2.1 on Vista as I had to install Servoy on the W7 machine. With Vista it does not work.

Yes, I just saw that, tried with Vista/Servoy 5.2.1/IE8.
Actually the problem seems to be coming from the callback in the onLoad/onShow function.
If you do the same script from another type of event (try calling it from a button but with no onLoad call), this works on Vista as well…
I know that there was something fishy about it and I coded a workaround specifically , but I would never have imagined that it would react differently depending on the client OS platform.
I have tested on Win XP and Win 7 with IE7/8 - Firefox 3.6 - Chrome 8 and Mac OS X Snow Leopard with Safari 5 and Firefox 3.6 and didn’t encounter the problem.
Will have a better look at that call from onLoad/onShow, to find a better workaround.

Thanks for the help.
