Fires when the user clicks the left mouse button on the object.
Note Starting with Internet Explorer 11, this event fires a MSPointerEvent object instead of MouseEvent. You can use the MouseEvent.pointerType property to determine the type of contact that the click originated from (touch, mouse, or pen).

Event handler parameters
- pEvtObj [in]
- HTML 4.01 Specification, Section 18.2.3
If the user clicks the left mouse button, the HTMLElementEvents2::onclick event for an object occurs only if the mouse pointer is over the object and an HTMLElementEvents2::onmousedown and an HTMLElementEvents2::onmouseup event occur in that order. For example, if the user clicks the mouse on the object but moves the mouse pointer away from the object before releasing, no HTMLElementEvents2::onclick event occurs.
The HTMLElementEvents2::onclick event changes the value of a control in a group. This change initiates the event for the group, not for the individual control. For example, if the user clicks a radio button or check box in a group, the HTMLElementEvents2::onclick event occurs after the HTMLElementEvents2::onbeforeupdate and HTMLElementEvents2::onafterupdate events for the control group.
If the user clicks an object that can receive the input focus but does not already have the focus, the HTMLElementEvents2::onfocus event occurs for that object before the HTMLElementEvents2::onclick event. If the user double-clicks the left mouse button in a control, an HTMLElementEvents2::ondblclick event occurs immediately after the HTMLElementEvents2::onclick event.
Although the HTMLElementEvents2::onclick event is available on a large number of HTML elements, if a document is to be accessible to keyboard users, you should restrict its use to the a, input, area, and button elements. These elements automatically allow keyboard access through the TAB key, making documents that use the elements accessible to keyboard users. For more information, please see the section on writing accessible Dynamic HTML.
Initiates any action associated with the object. For example, if the user clicks an a object, the client loads the document specified by the IHTMLLinkElement4::href property. To cancel the default behavior, set the IHTMLEventObj::returnValue property of the event object to FALSE.
To invoke this event, do one of the following:
- Click the object.
- Invoke the IHTMLElement::click method.
- Press the ENTER key in a form.
- Press the access key for a control.
- Select an item in a combo box or list box by clicking the left mouse button or by pressing the arrow keys and then pressing the ENTER key.
