Javascript learning notes (onchange, etc)

1. onchange and its onpropertychange, oninput

In IE, you can use onpropertychangel to immediately trigger the listener,
Oninput can be used in FF, but events must be bound using the addEventListener method recommended by w3c.

2. <button> </button> also has the type attribute:
The input tag is rarely used. Today, the developer uses the button to describe how to use the same tag as the submitted tag in ff. the user can check the manual and find that the type attribute value of the button is submit reset button, in my impression, it is a button, and it is wrong ..
In addition, this label is different by default in IE and ff, and in IE, It is a button and in ff, It is a submit, so click this button under Firefox and submit

3. Attributes of jquery's attr href:
The omnipotent jquery does not eliminate the compatibility issue of finding different href values. In IE, you can use ele. getAttribute ("href", 2) to set the second parameter to 2 to obtain the normal attribute value. For details, refer:

The http://jsfox.cn/blog/javascript/get-right-href-attribute.html;http://msdn.microsoft.com/en-us/library/ms536429 (VS.85). aspx

In addition, IE8 has eliminated this problem. When jQuery load is used to embed a page, the href on this page under IE has been changed, and ele. getAttribute ("href", 2) returns an absolute address.
