What do you mean by jQuery?

jQuery is a fast, lightweight, small, and feature-rich JavaScript library.

</script>

Use the jQuery: selected selector in combination with val () method to find the selected option value in a drop-down list.

The selector in jQuery:

It is an HTML element in which the declaration is applied.

For Example: selected, checked, etc.

Selected is used to specify the default choice when the form is initially loaded.

val () method in jQuery:

This method is used to get the values of form elements or set the value of attribute used for the selected elements.

Syntax:

Example:

Dropdown list with <select> and <option> tag.

The select and option tags are used to create drop-down menus. They allow the user to select single or multiple choices from a list of options. All the choices are not shown on the screen, but they are visible when they pull the drop-down list. They are used to save space as only one item of the list is displayed.

For creating Pull down lists, <select> tag is used instead of <input> tag. The paired tag starts with the opening <select> tag and ends with the closing tag </select>. This tag has to be used with the <option> tag.

Syntax:

The various attributes used with the <select> tag are:

  • Multiple: It is used to set the <select> tag to accept numerous options. By default, it can take a single option selected by the user. To select multiple options, a user has to press click while clicking the option.
  • Name: It is used to specify a name for the pull-down list.

The various attributes used with <option> tag are:

  • Value: It is used to specify the value that is sent when the form is submitted. If the value attribute is omitted in the <option> tag, then the <option> title contents are used.
  • Selected: It is used to specify the preselected choice when the form is initially loaded in a browser.
