In order to display data/content of a specific element by selecting the particular dropdown menu in jQuery, we can use the with following ways:
- Using hide() and show() methods:
- hide() methods : This method is used to hiding the syntax or the element of html that you want to hide.
Syntax:
$(selector).hide(speed, callback);
- show() methods : This method is used to show the syntax or the element of html that you want the user to see.
Syntax:
$(selector).show(speed, callback);
- Selector name for dropdown menu is same as the element which is used to display the content.
- Store the values of the selected elements in variable using .attr() method.
- Now check for the element whether any element is selected or not.
- If yes, use show() method for displaying the element for the selected element, otherwise use hide() method for hiding.
