Javascript – How to access the original element from the jQuery wrapper

javascriptjquerywrapper

Assuming I have this:

var wrap = $("#someId");

I need to access the original object that I would get by 

var orig = document.getElementById("someId");

But I don't want to do a document.getElementById.

Is there something I can use on wrap to get it? something like:

var orig = wrap.original();

I searched high and low but I didn't find anything; or maybe I'm not looking for the right thing.

The function for this is get. You can pass an index to get to access the element at that index, so wrap.get(0) gets the first element (note that the index is 0-based, like an array). You can also use a negative index, so wrap.get(-2) gets the last-but-one element in the selection.

wrap.get(0);  // get the first element
wrap.get(1);  // get the second element
wrap.get(6);  // get the seventh element
wrap.get(-1); // get the last element
wrap.get(-4); // get the element four from the end

You can also use array-like syntax to access elements, e.g. wrap[0]. However, you can only use positive indexes for this.

wrap[0];      // get the first element
wrap[1];      // get the second element
wrap[6];      // get the seventh element
