JQuery :: How To Clear Select Field

Aug 6, 2009

So before I used jQuery I had this approach to set select field as not selected. So the question is what would be the equivalent way to do it in jQuery?
Code JavaScript:
if (tag == 'select'){
this.selectedIndex = -1;
}

On Change Select Option, Clear Fields?

Aug 29, 2010

I have a select dropdown with several options. The user selects an option and fills out the following few fields. If the user then changes his mind and changes the option in the dropdown, I want all the fields - or just the ones already filled out - to be cleared.

Note: reset() of the form is not an option as there are other things going on (hide/display of fields based on the dropdown option selected).

JQuery :: Deselecting All Items In A <select>-field?

Jan 13, 2008

This is something I spent way too much time on, trying to figure out why it didn't want to do what I wanted in IE7. I'm posting it here, so maybe it will save some others a bit of time. The problem: You have a <select> and you wish to deselect all options. It turns out that you need to change the code, depending on whether you're using a select that can take multiple options or not. Both versions work in FF and Safari for both variants, but for Internet Explorer you'll need to use them as specified below.

JQuery :: Populate Select Form Field?

Jan 26, 2010

I have a form where a user may select a box from above which will query the database and autofill in the fields. This works properly for all of my input text fields but I have a select box where a user selects their state that I am unable to get to properly populate.

The select box is populated on page load in the following format....

<select id="state" name="state">
<option value="1">ALABAMA</option>
<option value="2">ALASKA</option>
</select>

[Code]....

Everything populates correctly except where I try to set the val on the state select field. It does not change at all. I need it to display the statename with the value of the state (number).

JQuery :: Change Event On A Select Field When The SelectedIndex Or Val Is Set?

Nov 1, 2010

Is it possible to trigger a change event on a select field when the selectedIndex or val is set with jQuery? I've tried it and it doesn't seem to work. I'm attempting to replace a select field with one of my own design. The issue is if i attached a change event to a select field, when the index is changed it needs to fire that event. Basically if a select field is replaced with my list and a seperate script is set on the select list, I need that seperate script to fire without knowing what it is.
