Dom node removal code

// Set the function of the close and OK buttons -- close (remove) prompt box
BtnEnter. onclick = aClose. onclick = function (){
Document. body. removeChild (objId );
Document. body. removeChild (shadow );
BtnShow. disabled = false;

Add nodes to dom


Document. body. appendChild (shadow );
Obj. appendChild (divTitle );
Obj. appendChild (Container );
Obj. appendChild (msgBottom );
Document. body. appendChild (obj );


Var Btns = document. createElement ("div ");
Btns. setAttribute ("id", "btns ");
Var btnEnter = document. createElement ("");
BtnEnter. setAttribute ("id", "btnEnter ");
BtnEnter. setAttribute ("href", "#1 ");
Var txtEnter = document. createTextNode ("OK ");
BtnEnter. appendChild (txtEnter );
Btns. appendChild (btnEnter );

Js close layer

Var closeBar = document. createElement ("div ");
CloseBar. setAttribute ("id", "closebar ");

Var A = document. createElement ("");
In the pure DOM method, we write as follows:
Var txtCloseWindow = document. createTextNode ("Close Window ");
A. appendChild (txtCloseWindow );
A. innerHTML = "Close Window ";
A. setAttribute ("href", "#1 ");
A. setAttribute ("id", "btnClose ");
A. setAttribute ("title", "Close Window ");
CloseBar. appendChild ();
