Question

I am trying to assign an object to another other in jQuery but I am getting error. I am quite new to jQuery so all helps are much appreciated. Following is the code i am trying to do.

 while ($(obj)) {

        $(obj) = $(obj).children(":first");

    }

It is trying to traverse through a table.

$(obj) will always be considered as true, you are doing an infinite loop.

At least, you should do while ($(obj).length), and you can’t assign $(obj).children(":first") to $(obj), $(obj) is not a variable. So maybe what you want to do is like below.

var element = $(obj);
while (element.length) {
    element = element.children(":first");
}
