window.onerror is used to catch and supress the script error. but it
will catch the error only when the script is within the same source
file.

for example, consider a html file MainFrame.htm as,

<IFRAME src="ScriptErro r.jsp" id="controllerF rame"
name="controlle rFrame" height=150 width="450"
APPLICATION="ye s"></IFRAME>
<BR>
<DIV id=oErrorLog style="border:1 px groove orange
;width:450px;he ight:200px; "></DIv>
<SCRIPT>
var frm=document.fr ames;
window.onerror= fnErrorTrap;
oErrorLog.inner HTML=frm(1).nam e;
function fnErrorTrap(sMs g,sUrl,sLine){
alert("err");
oErrorLog.inner HTML="<b>An error was thrown and caught. </b><p>";
oErrorLog.inner HTML+="Error: " + sMsg + "<br>";
oErrorLog.inner HTML+="Line: " + sLine + "<br>";
oErrorLog.inner HTML+="URL: " + sUrl + "<br>";
return true;
}
</SCRIPT>

ScriptError.jsp is as:

<BODY>
<INPUT TYPE="text" ID=oErrorCode VALUE="someObje ct.someProperty =true;">
<script>
document.write( eval(oErrorCode .value));
</script>
</BODY>

in the script of MainFrame.htm, frm(1) is null object and the error is
catched and suppressed, but the file scriptError.jsp also has the
script errror. what i need is to catch the error in scriptError.jsp
also from the MainFrame.htm, is it possible to catch the error?

You could add a line like this:

window.frames[yourframename].onerror=fnErro rTrap;

before or after the content of the frame has been written, you 'll need to
experiment with that..
Or add a error trapping function in your document.write statement.
