<htm:table id="htmtable1" border="0" width="100%" >

<htm:tr>

<htm:td width="60%" styleClass="lableStyleLeft">

<h:selectOneRadio id="rptType" layout="lineDirection" value="Admin_Agent_Report" styleClass="pr_boldInner" onclick="loginauditReportChk();">

<f:selectItem id ="rpttype1" itemLabel="Admin/Agent Report" itemValue="Admin_Agent_Report" />

<f:selectItem id ="rpttype2" itemLabel="Login Audit Report" itemValue="Login_Audit_Report" />

</h:selectOneRadio>

</htm:td>

<htm:td width="40%">

<hutputText/>

</htm:td>

</htm:tr>

</htm:table>

I have the javascript function below


function loginauditReportChk(){

alert('from inside loginauditReportChk js');
var var1=document.getElementById("adminPanel:adminForm:rptType");
alert(var1 + " - " + var1.value);

}

The last alert above doesnt provide me the desired results ie. the element name and the value. It tells me that var1 is a HTMLTableObject and var1.value comes as undefined or null. Please assist on the below questinos :
1 . I read smwhere in this forum that the document is not yet created hence the issue...could someone please elaborate this point.
2. Am using tomcat to run the applciation. Am I missing any jars, if so what are they.

Try accessing your element in this way.

document.getElementById("rptType");

Also am using safari as my browser. So please let me know if that could be the issue and the fix to overcome the same. Thanks.

when you post code, use code tags!

View the page source, what is the id. Looking at serverside code is useless.

I have closed this topic. When posting to this forum, post the rendered HTML not the JSF source.
