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.
function displayHideUI()
{
var ui =document.getElementById("bbs");
ui.style.display="none";
}
function displayShowUI()
{
var ui =document.getElementById("bbs");
ui.style.display="";//display为空的话会好使，为block会使后边的空间换行
}
function visibilityHideUI()
{
var ui =document.getElementById("bbs");
ui.style.visibility="hidden";
}
function visibilityShowUI()
{
var ui =document.getElementById("bbs");
ui.style.visibility="visible";
}

table This element will be displayed as a block-level table (similar to
| and | ) table-caption This element will be displayed as a table title (similar to inherit specifies that the value of the display attribute should be inherited from the parent element. The problem solved today is to give the label.error class defined by css an id in the jsp page, and then control the visibility of the id to clear the js prompt information when the div is collapsed. The details are as follows:
$(document).ready(function() {
$(".flipp .span4").click(function() {
$(this).parent().next().toggle();
$(this).parent().parent().prevAll().find(".panel").hide();
$(this).parent().parent().nextAll().find(".panel").hide();
var label1 = document.getElementById("label1");
label1.style.display="none";
})Copy after login Then add in the corresponding place in jsp: <label class="error" id="label1" for="currentPWD" generated="true" style="display:inline"></label> Copy after login For the label.error class defined by CSS, you can use $("label.error").removeAttr("style").attr("style", "display: none;"); to achieve the above function. Moreover, it seems that there is no need to define the id value for the label at the corresponding location underground.
