jQuery UI Draggable option() Method

  • Last Updated : 20 Jan, 2022

jQuery Mobile is a web-based technology that can be used to make responsive content for websites that can be accessed on all types of smartphones, tablets, and desktops.

In this article, we are going to learn the jQuery Mobile Draggable option() method. Using this method, we can get, set or update any parameter’s value of the Draggable widget. We can also get all the options as key-value pairs using this method.

Syntax:

1. If the user wants any option’s value, the option name should be passed in the option(optionName) method. The optionName should be a string type.

var isEnhanced = $("Selector").draggable("option", "enhanced");

Parameter:

  • optionName: This parameter is the input that we need to pass in the form of a string for which we need to get the value.
  • Return type: We get the respective return value based on the option data type.

2. To get all the options as the key-value pairs, you just need to call the option() method with no parameter is passed to the method.

var options= $("Selector").draggable("option");

Return type: This method returns the list of key-value pairs of all the options as optionName-optionValue pairs set.

3. To set the value of any option, you just need to call the option(optionName, value) with the optionName and the value as the parameters.

$("Selector").draggable("option", "enhanced", "false");

Parameters:

  • optionName: The option method required the option name as the first parameter and this parameter is of string type.
  • value: The option method required the option’s name as the second parameter and this parameter is of string type.

4. We can also set multiple options instead of only one, you just need to call the option(options) method where options are the list of options.

$("Selector").draggable("option", {enhanced: false, disabled: true});

Parameter:

  • option: It is the map of the optionName-value pairs as input to set the options corresponding to the values passed, which is of the object type.
