In jquery, the select operation is much more convenient. If I want to obtain the selected select value, we can directly $ (\ '# s option: selected \'). val (). The following is a brief introduction to this topic.

Jquery obtains the selected text and value of select.

The Code is as follows: Copy code

Obtain the selected text: jQuery ("# select1 option: selected"). text ();

Obtain the value selected by select: $ ("# ddlregtype"). val ();
Obtain the index selected by select: $ ("# ddlregtype"). get (0). selectedindex;

The selected value is displayed.

The Code is as follows: Copy code

<Script src = "jquery-1.9.1.js"> </script>
<Script type = "text/javascript">
$ (Function (){
$ ('# Btn'). click (function (){
Alert ($ ('# s option: selected'). val ());
})
})
</Script>
</Head>
<Body>
<Select id = "s" multiple = "multiple">
<Option value = "1"> operator </option>
<Option value = "2"> Bing </option>
<Option value = "3"> odd </option>
</Select>
<Input type = "button" id = "btn" value = ""/> <br/>
</Body>

Other select option operations

Set select option items:

The Code is as follows: Copy code

$ ("# Select_id"). append ("<option value = 'value'> text </option>"); // Add an option
$ ("# Select_id"). prepend ("<option value = '0'> select </option>"); // insert an option
$ ("# Select_id option: last"). remove (); // Delete the option with the largest index value
$ ("# Select_id option [index = '0']"). remove (); // delete an option with an index value of 0
$ ("# Select_id option [value = '3']"). remove (); // delete an option with a value of 3
$ ("# Select_id option [text = '4']"). remove (); // delete an option with a text value of 4
