This and $ (this)

At first thought this and $ (this) is a die carved out. But when I read, and coding, it's not the same thing.

Here this is actually an HTML element (textbox), TextBox has the Text property, so it is absolutely no problem to write.

$ ("#textbox"). Hover (         function() {              this. title = "Test";         },         fucntion () {             this. title = "OK";         }   );   

But if you change this to $ (this) it is not the case, error--reported.

Error Code:  $ ("#textbox"). Hover (         function() {            $ (this). title = "Test";         },         function() {            $ (this). title = "OK";         }  );

The $ (this) here is a jquery object, and the jquery object does not have the title property, so it is wrong to write this.

jquery has the attr () method to get/set the properties of Dom objects, so the correct wording should be:

the correct code:  $ ("#textbox"). Hover (        function() {           $ (this). attr (' title ', ' Test ');        },        function() {           $ (this). attr (' Title ', ' OK ');        }  );
