Use jQuery to change a second select list based on the first select list option
html, jquery, select
Solution
$("#select1").change(function() {
if ($(this).data('options') === undefined) {
/*Taking an array of all options-2 and kind of embedding it on the select1*/
$(this).data('options', $('#select2 option').clone());
}
var id = $(this).val();
var options = $(this).data('options').filter('[value=' + id + ']');
$('#select2').html(options);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.0.0/jquery.min.js"></script>
<select name="select1" id="select1">
<option value="1">Fruit</option>
<option value="2">Animal</option>
<option value="3">Bird</option>
<option value="4">Car</option>
</select>
<select name="select2" id="select2">
<option value="1">Banana</option>
<option value="1">Apple</option>
<option value="1">Orange</option>
<option value="2">Wolf</option>
<option value="2">Fox</option>
<option value="2">Bear</option>
<option value="3">Eagle</option>
<option value="3">Hawk</option>
<option value="4">BWM<option>
</select>
Using jQuery data() to store data
I guess hiding elements doesn't work cross-browser(2012), I have'nt tested it myself.
Problem
I have two selects: ``` <select name="select1" id="select1"> <option value="1">Fruit</option> <option value="2">Animal</option> <option value="3">Bird</option> <option value="4">Car</option> </select> <select name="select2" id="select2"> <option value="1">Banana</option> <option value="1">Apple</option> <option value="1">Orange</option> <option value="2">Wolf</option> <option value="2">Fox</option> <option value="2">Bear</option> <option value="3">Eagle</option> <option value="3">Hawk</option> <option value="4">BWM<option> </select> ``` How do I do that with jQuery if I choose Fruit in the first select? The second select would show me only Fruits - Banana, Apple, Orange. If I choose Bird in the first select, the second select would show me only Birds - Eagle, Hawk. And so on... I tried to do it with this piece of jQuery code: ``` $("#select1").change(function() { var id = $(this).val(); $('#select2 option[value!='+id+']').remove(); }); ``` Unfortunately, it removes almost everything, and I have no idea how to bring back some options. I also read something about clone, but I don't know how to use it in this case.
