jquery Action Properties

1. Setting individual properties

//第一个参数：需要设置的属性名//第二个参数：对应的属性值attr(name, value);//用法举例$("img").attr("title","哎哟，不错哦");$("img").attr("alt","哎哟，不错哦");

2. Setting multiple properties

//参数是一个对象，包含了需要设置的属性名和属性值attr(obj)//用法举例$("img").attr({    title:"哎哟，不错哦", alt:"哎哟，不错哦", style:"opacity:.5"});

3. Get Properties

 //to get the property name, return the corresponding property value attr (name) //usage Example var otitle = $ ( "img"). attr ( "title" ); alert (otitle);        

note:

• When you get a property, you get only the property that corresponds to the first element, just like the CSS method

"Case: Beauty Album"

4. Removing attributes

//参数：需要移除的属性名，如果传空，那么不会有任何操作，注意，并不是移除所有的属性。区分removeClass。removeAttr(name);//用法举例$("img").removeAttr("title");

Prop Method

note:

//设置属性$(":checked”).prop("checked",true);//获取属性$(":checked").prop("checked");//返回true或者false
