ZK - Open Source Ajax Java Framework

Hi all

I'm trying to open pdf in web browser using ZK. I want to detect if Adobe plugin is available in the browser. I searched and found many working samples to do this in JavaScript but couldn't find any material to do it in zscript :( . can any one help me with material to do this and any sample code would be very much appretiated.

To run javascript in browser, you have to use <script>, not <zscript>

I have written java script for checking plugin and its working fine.. but i'm not able to access result of the validation in my zul file.. is there a way to return value from javascript to zscript ?

can anyone tell me how i can access navigator object inside zscript ?

i wrote the following code

<?page zscript-language="javascript"?>
<window id="window" title="">
<zscript>

function detectadobe(){
var acrobat=new Object();

acrobat.installed=false;
acrobat.version='0.0';
acrobat.ok=false;

if (navigator.plugins && navigator.plugins.length){
for (x=0; x<navigator.plugins.length; x++){
if (navigator.plugins.description.indexOf('Adobe Acrobat') != -1){
acrobat.version=parseFloat(navigator.plugins.description.split('Version ')[1]);
if (acrobat.version.toString().length == 1)
acrobat.version+='.0';
acrobat.installed=true;
// Verify whether Acrobat Plug In installed is for Version 7 or above
acrobat.ok=(acrobat.installed && parseInt(acrobat.version) >= 7) ? true:false;
if(acrobat.ok){
window.title="got it";
}
break;
}
}
}
}
</zscript>
<button label="button">
<attribute name="onClick">
detectadobe();
</attribute>
</button>
</window>

i get the following error
