Remove Duplicates From Two Select Boxes
I have two selects. The first being the select to remove the options from, and the second being the source to find duplicates from.
How do I use jQuery to remove the the options from the first, if, and only if the option value is in the first and the second select?
Would like a function, something like:
removeDuplicates($("#select_1"), $("#select_2");
Thanks very much.
EX:
BEFORE DUPLICATES REMOVED:
[1st Select]
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
[2nd Select]
<option value="1">1</option>
<option value="3">3</option>
AFTER DUPLICATES REMOVED (FINAL RESULT):
[1st Select]
<option value="2">2</option>
[2nd Select]
<option value="1">1</option>
<option value="3">3</option>
