In jquery, you can determine whether a string has values in the following ways, and use the IF else if statement to handle business logic.

Bloo"). Text ()//The trim () method should be the return list, which can determine the length            if(Data.trim (). Length>0){                //Business Logic            }Else if(Data.trim (). Length=0){                //Business Logic            }Else{                //Business Logic            }        }); </Script></Head><Body>    <Divclass= "box"a="">Hey</Div>    <inputtype= "text"value= "hehe">    <Divclass= "Bloo"></Div></Body></HTML>
