How do you select a particular option in a SELECT element in jQuery?

Question

If you know the Index, Value or Text. also if you don\'t have an ID for a direct reference.

This, this and this are all helpful answers.

Example markup

Answer 1

For setting select value with triggering selected:

$('select.opts').val('SEL1').change();

---

For setting option from a scope:

$('.selDiv option[value="SEL1"]')
    .attr('selected', 'selected')
    .change();

This code use selector to find out the select object with condition, then change the selected attribute by attr().

---

Futher, I recommend to add change() event after setting attribute to selected, by doing this the code will close to changing select by user.
