Get value from select menu jquery mobile
The select menu is based on a native select element, which is hidden from view and replaced with a custom-styled select button that matches the look and feel of the jQuery Mobile framework. The select menu is ARIA-enabled and keyboard accessible on the desktop as well. By default, the framework leverages the native OS options menu to use with the custom button. When the button is clicked, the native OS menu will open.
When a value is selected and the menu closes, the custom button's text is updated to match the selected value. Please note that the framework also offers the possibility of having custom non-native select menus.
To add a select menu to your page, start with a standard select element populated with a set of option elements. Set the for attribute of the label to match the id of the select so they are semantically associated. It's possible to accessibly hide the label if it's not desired in the page layout, but we require that it is present in the markup for semantic and accessibility reasons. The framework will find all select elements and automatically enhance them into select menus, no need to apply a data-role attribute.
The selectmenu widget uses the jQuery Mobile CSS framework to style its look and feel. If selectmenu specific styling is needed, the following CSS class names can be used for overrides or as keys for the classes option:.
This will produce a basic select menu.
This will produce a select that a not as tall as the standard version and has a smaller text size. Optionally wrap the selects in a container with class ui-field-contain to help visually group it in a longer form. Add class ui-field-contain instead. The select input is now displayed like this: An example of a select with a long list of options: The following example organizes the options into optgroup elements. Support for this feature in mobile selects is a bit spotty, but is improving.
To create a grouped set of select inputs, first add select and a corresponding label. Because the label element will be associated with each individual select input and will be hidden for styling purposes, we recommend wrapping the selects in a fieldset element that has a legend which acts as the combined label for the grouped inputs.
Select inputs can also be used for grouped sets with more than one related selections. You can specify any jQuery Mobile button data- attribute on a select element, too.

The custom menu supports disabled options and multiple selection whereas native mobile OS support for both is inconsistentadds an elegant way to handle placeholder values, and restores missing functionality on certain platforms such as optgroup support on Android all explained below.

Lastly, custom menus often look better on desktop browsers because native desktop menus are smaller than their mobile counterparts and tend to look disproportionate.
Keep in mind that there is overhead involved in parsing the native select to build a custom menu. If there are a lot of selects on a page, or a select has a long list of options, this can impact the performance of the page, so we recommend using custom menus sparingly.
