You can use JavaScript to hide controls by setting the "display" and "visibility" attributes of the style, the following describes how to use JavaScript to hide a widget. You can set the "display" and "visibility" attributes of the style. When style. display = "block" or style. visibility = "visible" when the Controller or see, when style. display = "none" or style. visibility = "hidden" when the controller is invisible. The difference is that "display" not only hides the control, but hidden controls no longer occupy the position occupied by the display. The "visibility" hidden control only sets the control to invisible, the widget still occupies the original position.
The Code is as follows:
Function displayHideUI ()
{
Var ui = document. getElementById ("bbs ");
Ui. style. display = "none ";
}
Function displayShowUI ()
{
Var ui = document. getElementById ("bbs ");
Ui. style. display = ""; // If the display is empty, it will be easy to use.
}
Function visibilityHideUI ()
{
Var ui = document. getElementById ("bbs ");
Ui. style. visibility = "hidden ";
}
Function visibilityShowUI ()
{
Var ui = document. getElementById ("bbs ");
Ui. style. visibility = "visible ";
}
