Last Updated :
20 Jan, 2022
jQuery Mobile is a web-based technology used to make responsive content that can be accessed on all smartphones, tablets, and desktops.
In this article, we will be using the jQuery Mobile Selectmenu option() method. Using this method, we can get, set or update any parameter’s value of the Selectmenu widget. We can also get all the options as key-value pairs using this method.
Syntax:
1. If we need any option’s value, pass the option name in the option(optionName) method. The optionName should be a string.
- optionName: It is the input that we need to pass in form of a string for which we need to get the value.
- return: We get the respective return based on the option data type.
var isDisabled = $( ".selector" ).selectmenu( "option", "disabled" );
2. Get all the options with their values as key-value pairs by just calling the option method with no parameters.
- input: We need to call the option method. Nothing should be passed as input.
- return: We get the list of key-value pairs of all the options as optionName - optionValue.
var options = $( ".selector" ).selectmenu( "option" );
3. Set the value of any option by calling the option(optionName, value) with the optionName and the value as parameters
- optionName: The option name is the first parameter, which is of string type.
- value: While calling the method, we need to pass the option’s value, which is of the object type.
$( ".selector" ).selectmenu( "option", "disabled", true );
4) To set multiple options instead of only one, call the option(options) method where options are the list of options.
- options: It is the map of the optionName-value pairs to set the options corresponding to the values passed, which is of the object type.
$( ".selector" ).selectmenu( "option", { disabled: true } );
