var a = g_form.getValue('task_number');

Bring the field on the form display and hide it using g_form.setDisplay

Then you will be able to read it as its present on the form. if its not in the layout itself then you will have to read it from server side and will have to make an ajax call for it, long way.

you need to use display business rule and and get the field value thrugh g_scratchpad and call it in client script.

check the script below i have tested it and it's working.

Display BR:

(function executeRule(current, previous /*null when async*/) {

// Add your code here

g_scratchpad.categoryfield = current.category.getDisplayValue();

})(current, previous);

Client script:

function onLoad() {

    //Type appropriate comment here, and begin script below

    alert('testing ' + g_scratchpad.categoryfield);

}

Thanks,
