In order to select an option using the text description given, we need to set the attribute of that particular option as 'selected'. But before that, we need to provide a way to set the option based on the text description. This will be achieved using the :contains selector in jQuery.

jQuery :contains() Selector

The jQuery :contains(text) selector allows you to select the element that contains a specific string in it. You can specify the string on the basis of which the elements can be filtered out. The mentioned string is searched all over the document and hence, it provides you with the elements containing that string.

Syntax:

$('element : contains(text)');

This selector needs a required parameter – text, which is the string that you specify over here to be searched. The selector is used along with ':' symbol in front.

Hence, this will allow you to provide the text of the option that you wish to select. Once this is done, the attribute will be set to 'selected' as 'true' which will return the result as the selected option in the drop-down menu.

jQuery attr() Method

The attr() method helps to set or return the attribute of the selected element. When the attribute has to be set, then along with the property name, property value is also to be given.

Syntax:

$('selector').attr('propertyName');
$('selector').attr('propertyName','value');

In the example given below, when the user clicks on the button provided, it automatically sets the drop-down option as 'Wednesday'.
