Delete a subnode created by javascript

Source: Internet
Author: User

The created node does not know how to delete it at the moment... It took a lot of time

For (var I = 0; I <jsonList. length; I ++ ){
Var li_button = document. createElement ("li ");
Li_button.className = "button ";
Var li_button_a = document. createElement ("");
Li_button_a.id = jsonList [I]. _ id;

Var li_button_text = document. createTextNode (jsonList [I]. projectName );
Li_button_a.appendChild (li_button_text );
Li_button.appendChild (li_button_a );
Ul_level2.appendChild (li_button );

}

Later I learned that the node is actually

Ul_level2.innerHTML = ''; the content of innerHTML =''. You only need to leave it blank and you can clear the subnode.
