Question

The Javascript timer event has this basic syntax:

var t=setTimeout("javascript statement",milliseconds);

I have this function that gets called onkeyup() for some text box. I want the numeric_value_search() function to be called after a certain amount of time, which is 5 seconds in this example.

The key line is the 5th line. I have four different ways that it might be written, each of which gives the specified error:

    timer=setTimeout(numeric_value_search(boundBox),5000);

ERROR: useless setTimeout call (missing quotes around argument?)

    timer=setTimeout("numeric_value_search(boundBox)",5000);

ERROR: boundBox is not defined

    timer=setTimeout("numeric_value_search("+boundBox+")",5000);

ERROR: missing ] after element list

    timer=setTimeout(numeric_value_search("+boundBox),5000);

ERROR: data is passed nicely and there are no explicit errors but the timer doesn’t work

var timer;
function chk_me(boundBox){
console.info(boundBox.id);
    clearTimeout(timer);
//  --- timer code here ---   e.g. timer=setTimeout("numeric_value_search("+boundBox+")",5000);
}

Try this:

setTimeout(function() {
    numeric_value_search(boundBox);
}, 5000);
