display Attributes

There are two ways to hide controls using JavaScript, one is by setting the "display" and "visibility" attributes of the control's style. The control is visible when style.display="block" or style.visibility="visible", and is invisible when style.display="none" or style.visibility="hidden". The difference is that "display" not only hides the control, but also the hidden control no longer occupies the position occupied when displayed, while the control hidden by "visibility" only sets the control to be invisible, and the control still occupies its original position.

Copy code 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=" ";//It will work if the display is empty, and the block will cause the following space to wrap 
}
function visibilityHideUI()
{
 var ui = document.getElementById("bbs");
 ui.style.visibility="hidden";
}
function visibilityShowUI()
{
 var ui = document. getElementById("bbs");
 ui.style.visibility="visible";
}
