Reprimand Replace Option Field For Free

To change the selected option color of the menu, the ?:checked? selector of CSS is used. :checked is a pseudo-class element that can be only linked with input type elements, such as ?option?, ?checkbox?, and ?radio buttons?. It is mainly used to change the behavior of the selected value of these elements.

Use the add() method of the HTMLSelectElement to add an option to the <select> element. Use the remove() method of the HTMLSelectElement to remove an option from the <select> element.

You can either select text or find the position of it in a drop-down list by using the option:selected attribute or the val() method in jQuery. The val() method returns the value of selected attribute value. let selectedValue = $("#selectVal option:selected"). val();

To change the selected option in an HTML <select> element you have to change the value property on the <select> element or the selected property on the <option> element you want to select. There are multiple ways you can do it and choosing one or another will depend on the information you have available.

Method 1: Add Option to Select Tag From Input Text Using add() Method with Option Constructor. For adding an option from the input text in a select tag, use the ?add()? method with ?Option? Constructor. The add() method is used to add the elements to the options of the ?HTMLSelectElement? also known as <select> tag.

The default value of the select element can be set by using the 'selected' attribute on the required option. This is a boolean attribute. The option that is having the 'selected' attribute will be displayed by default on the dropdown list.

Essentially what you need to do is use the option selector in order to grab the element you want, then it is fairly trivial. $('#selectID option[value="knownValue"]'). text('New Option Text'); So what we are saying here is for every element with the ID of 'selectID' look for an option with the value of 'knownValue'.
