Reliable way to get the "ancestor" of an object with a specific classname, using jQuery
- by Matt Dawdy
I've got a javascript function that gets called on change event of a select form element. So, the "this" variable in js refers to the select element.
This select element is in a td tag, in a tr tag. The tr tag has a classname of "FilterDetailsRow".
Now, I've tested, and if I use this syntax:
var filterRow = $(this).parent().parent();
it gets me what I want. However, is there a better way to tell jQuery, "starting with "this" can you please go up my tree of parents until you find one with a classname of "FilterDetailsRow"?
Here's what I came up with, but I want to make sure I"m not reinventing the wheel.
function GetFilterDetailsRowOfObject(o) {
if (o) {
if (o.parent()[0].className.indexOf("FilterDetailsRow") != -1)
return o;
else
return GetFilterDetailsRowOfObject(o.parent());
} else {
return null;
}
}
Thanks for any advice.
