came across this on a web page source code...

try{top.document.title = 'Misc General Merchandise';}catch(E){};

any ideas?

It is for error catching seen frequently in Java (not that common in Javascript).

It says try {to set the document title to 'Misc General Merchandise'} and if an error occurs catch it (store error information in E) {and do nothing}

i.e.

try {
normal code that could go wrong
} catch (errorVariable) {
code to be run if there is an error
}

Quinnie, does Nutscrape support exception handling yet?

palbano,

Depends what you mean. Can't do this level of handling up until NS6 but can over-ride onerror event, which can show if you like.

try ... catch was added in JS1.4 for NS6
try ... catch with multiple catches was added in JS1.5 for NS6

Hope this is what you ment.
