Script ends abruptly with a Terminated message

Question

I am running the following javascript:

$('img').each(
    function(){
        var w = parseInt(this.width);
            alert(w);
            alert(this.src);
        if(w > 300){

            var percent = parseInt((w/666)*100);
            $(this).removeAttr('width height').css('width',percent + "%");

        }
});

And I am getting the following error:

Error: uncaught exception: [Exception... "String contains an invalid character" code: "5" nsresult: "0x80530005 (NS_ERROR_DOM_INVALID_CHARACTER_ERR)" location: "http://code.jquery.com/jquery-1.6.4.min.js Line: 2"]

I'm having trouble actually trying to track this one down as it isn't very descriptive of the problem or the source of the problem. Can anyone shed some light on the problem?

Thanks

Solution

When you are calling pkill -f resque it is also matching your script, sending it a SIGTERM. If you are unable to add additional restrictions on the pkill commands such as more exact matching, you will need to kill PIDs one at a time to ensure the script is not killing itself. Here is an example:

pids=( $(pgrep -f resque) )
for pid in "${pids[@]}"; do
  if [[ $pid != $$ ]]; then
    kill "$pid"
  fi
done

Why are you using escaped quotes? Use $('img').each(/*...*/);

[Rodaine]

Are the escapes (\) in your actual code?

That's a pretty accurate error code :) -- String contains an invalid character.

This is a lot of code for a simple bug. I would recommend trying to narrow down where in the code the problem occurs by removing lines until you find the one that it is on. Might even find the solution yourself before having to post it :)

stupid me, ignore the escapes, thats because they are in a php string. They aren't actually done when the document is printed.

I provided an answer to the question, but I also want to note that the script is broken by design. See: mywiki.wooledge.org/ProcessManagement

Thank you. I am taking a look at it, especially the process killing part.

Please provide the name of the script when you are using ps :-)

mypid=$$; pids=($(pgrep -f resque|grep -v $mypid))
