Html select onchange value

I am a novice at JavaScript and jQuery. Query get value of select onChange - Stack. HTML SELECT - Trigger JavaScript ONCHANGE event. The onchange attribute fires the moment when the value of the element is changed.

Tip: This event is similar to the oninput event.

The following HTML Markup consists of an HTML Select DropDownList. The HTML Select DropDownList has been assigned a JavaScript OnChange event handler. When an item is selected in the HTML Select DropDownList, the GetSelectedTextValue JavaScript function is executed to which the reference of the HTML. Both functions assigned to onchange use this: to reference the form containing the select, to reference other elements in the form, and to access the value of the selected option. Since the values of form elements are always strings, the parseFloat function is used to convert these values to floating point numbers.

It is a part of event attribute. But the difference is while oninput attribute event occurs immediately after the value of element changes, while onchange event occur when the element looses. Using the keyboard or an assistive technology that emulates the keyboar move focus to the select control.

When the value of the element is change if onchange attribute is use a script is executed. Syntax ElementName onblur= value. HTML onchange attribute supports input, select , textarea elements.

In this article I will explain how to get selected Text and Value of HTML Select DropDownList in OnChange event using jQuery. The change event is sent to an element when its value changes. For select boxes, checkboxes, and radio buttons, the event is fired immediately when the user makes a selection with the mouse, but for the other element types the event is deferred until the element.

Another JavaScript event that is quite similar to onchange is oninput. The difference is that oninput is triggered every time the value of an element changes even while it still is in focus. The event object is accessible to all event handlers in all browsers. The properties of the event object contain additional information about the current event.
