I have a function that is supposed to remove all child elements from a <select>
on the onfocus
event. (this is soon to be followed by filling the <select>
with values from an AJAX call) For some reason, it only removes one of the elements the first time it is called , and then proceeds to do nothing all subsequent calls. Does anyone have any clue as to why this might be happening?
JS Code:
function handle(e) {
for(var i = 0; i < e.children.length - 1; i++) {
e.removeChild(e.children[i]);
}
}
i'm guessing handle()
is your onfocus
event handler. in which case e
is your event object and doesn't have any children
property
why not just use select.innerHTML = ""
So the answer is simply to remove them in inverse order, as to avoid the effects of a indexing system quite similar to the VB.NET List Class. (That is that it reorganizes itself every time a change is made.
