I have 2 select options. I want to change the drop down options in second select options based on what I select in first select options. How do I do that in jquery?
<select id="Manage">
<option value="a">A</option>
<option value="b">B</option>
<option value="c">C</option>
<select>
Second select option if A is selected from first select option
<select id='selectA'>
<option value="1">1</option>
<option value="2">2</option>
</select>
Now if B is selected from first select option
<select id='selectA'>
<option value="3">3</option>
<option value="4">4</option>
</select>
Something like:
$('#Manage').change(function() {
var options = '';
if($(this).val() == 'a') {
options = '<option value="1">1</option><option value="2">2</option>';
}
else if ($(this).val() == 'b'){
options = '<option value="3">3</option><option value="4">4</option>';
}
$('#selectA').html(options);
});
Of course you can have your options e.g. stored in an array and combine them on fly or whatever, that is up to you.
Reference: .change()
, .val()
You can so that with 3 diffrent techniques:
The first is probably the best as you can get values from a database depending on the users fisrt choice and you can build the hole select server side.
