jQuery to remove an option from drop down list, gi

问题:

I have a drop down list and would like to remove an option from it, given the text/value of that particular option. Is it possible using jQuery? Just like 'append' which adds an option to the drop down list, is there a function to remove an option?

I tried searching for it but all I got were examples where the entire set of options in the drop down list are removed, which is not what I seek.

cheers

回答1:

$("option[value='foo']").remove();

or better (if you have few selects in the page):

$("#select_id option[value='foo']").remove();

回答2:

Once you have localized the dropdown element

dropdownElement = $("#dropdownElement");

Find the <option> element using the JQuery attribute selector

dropdownElement.find('option[value=foo]').remove();

回答3:

$('#id option').remove();

This will clear the Drop Down list. if you want to clear to select value then $("#id option:selected").remove();

I know it is very late but following approach can also be used:

<select id="type" name="type" >
    <option value="Permanent" id="permanent">I am here to stay.</option>
    <option value="toremove" id="toremove">Remove me!</option>
    <option value="Other" id="other">Other</option>
</select>

and if I have to remove second option (id=toremove), the script would look like

$('#toremove').hide();
