JavaScript Controlling the two ways of hiding the page control, the difference is that the control is hidden to place it on the page.
method one:
Document.all ["panelsms"]. style.visibility = "hidden";
Document.all ["panelsms"]. style.visibility = "visible";
Method Two:
Document.all ["panelsms"]. style.display = "none";
Document.all ["panelsms"]. style.display = "inline";
Methods The position of the page after hiding is also occupied by the control, but not displaying DISPLAY = static similar to .NET verification control
Method 2 The location of the page is not occupied by DISPLAY = Dynamic similar to .NET verification control.
