How does JavaScript ie prevent event bubbling?The IE event is different from other standard DOM events, and the bubble mechanism of different browser events is also different.
IE:
Window. event. cancelBubble = true; // stop bubbling
Window. event. returnValue = false; // block the default behavior of the event
Firefox:
Event. preventDefault (); // cancel the default event behavior.
Event. stopPropagation (); // prevents event Propagation
You can try other browsers on your own...

Event Represents the status of an event and is responsible for event processing. Its Attributes and methods can help us complete many operations that interact with users;
I. main attributes and methods of Event objects
1. type: the type of the event, which is a string without the "on" prefix in the HTML Tag attribute. For example, "Click" indicates the Click event.
2. srcElement: The Event source, which is the element of the event. For example, <a onclick = "check ()"> </a> a is the source of the event, that is, the srcElement of the event. (Target is not used in IE)
3. button: Declares the mouse key pressed, which is an integer. 0 indicates no buttons, 1 indicates the left mouse button, 2 indicates the right mouse, and 4 indicates the middle mouse key. If you press Multiple mouse keys, add these values together, so 3 indicates that the left and right keys are pressed simultaneously.
4. clientX/clientY: refers to the horizontal and vertical coordinates of the mouse when an event occurs. The return value is an integer. Their values are generated relative to the upper left corner of the inclusive window.
5. offsetX/offsetY: the position of the mouse pointer relative to the source element. You can determine which pixel of the Image object to click.
6. altKey, ctrlKey, and shiftKey: as the name suggests, these attributes indicate whether Alt, Ctrl, or Shift keys are simultaneously held when a mouse event occurs, and a Boolean value is returned.
7. keyCode: return the code of the key and the Unicode characters of the keypress event when the keydown and keyup events occur. For example, event. keyCode = 13 indicates that the Enter key is pressed;
8. fromElement and toElement refer to the document elements that the mouseover event has moved, and the former refer to the document elements that the mouse moves to in the mouseout event.
9. cancelBubble: A boolean attribute. When it is set to true, the Stop event is further flushed to an element of the inclusion level, which is used to detect whether the event control of the upper layer element is accepted. True indicates that the event is not controlled by the upper element, and false indicates that the event is allowed by the upper element.
10. returnValue: a boolean attribute. When it is set to false, it can prevent the browser from executing the default event action, which is equivalent to <a href = "#" onclick = "ProcessMethod (); return false; "&#...... remaining full text>
