How to implement hidden element function in jquery
This article mainly introduces the jquery method of hiding element p by clicking on the blank space and the implementation code. Let’s learn together.
When we develop websites, we often click on the blank space to hide existing elements, p or other elements. This time I will teach you how to use jquery to achieve this special effect.
A jQuery special effect to hide the pop-up layer when clicking on the blank space. Click on the button to pop up the layer. Click on the blank space on the page to disappear the pop-up layer. JS code. The main function is to click the button to display the pop-up layer, and then click anywhere on the page to close the pop-up layer display effect. It is mainly the operation application of $(document).click. Demonstration Demo, effect source code:
CSS code:
* {
padding: 0;
margin: 0;
}
#btnShow{
margin: 100px auto 0;
width: 90px;
display: block;
}
#pTop{
border: 2px solid #666666;
position: absolute; display: none;
width: 400px;
height: 200px;
color: #333;
background: #efefef;
padding-top: 10px;
text-align: center;
font: 16px/30px "微软雅黑";
margin-top: -105px;
margin-left: -200px;
left: 50%;
top: 50%;
}JS code:
$(function () {
$('#btnShow').click(function (event) {
//取消事件冒泡
event.stopPropagation();
//按钮的toggle,如果p是可见的,点击按钮切换为隐藏的;如果是隐藏的,切换为可见的。
$('#pTop').toggle('slow');
return false;
});
//点击空白处隐藏弹出层，下面为滑动消失效果和淡出消失效果。
$(document).click(function(event){
var _con = $('#pTop'); // 设置目标区域
if(!_con.is(event.target) && _con.has(event.target).length === 0){ // Mark 1
//$('#pTop').slideUp('slow'); //滑动消失
$('#pTop').hide(1000); //淡出消失
}
});
})HTML code:
<body> <input type="button" id="btnShow" value="弹出框按钮" /> <p id="pTop"> 点击空白区域弹出层关闭！ </p> </body>
After testing, when clicking on the blank space of the page on the mobile phone Iphone, the pop-up layer is closed and fails, and the document writing method is not supported. , Solution: You can add a background layer as a page blank object.
Click on the blank space to hide the pop-up layer Case 2:

.btn{color:red;}
</style>
<script type="text/javascript" src="http://www.internetke.com/public/js/jquery.js"></script>
<script type="text/javascript">
$(function(){
$(".btn").click(function(event){
var e=window.event || event;
if(e.stopPropagation){
e.stopPropagation();
}else{
e.cancelBubble = true;
}
$("#box").show();
});
$("#box").click(function(event){
var e=window.event || event;
if(e.stopPropagation){
e.stopPropagation();
}else{
e.cancelBubble = true;
}
});
document.onclick = function(){
$("#box").hide();
};
})
</script>
</head>
<body>
<p id="box"></p>
<span class="btn">点击此处打开弹出层</span><br>点击空白处关闭弹出层
</body>
</html>Let me share with you the code of the method of hiding the p area by clicking outside the p area in js:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<script type="text/javascript" src="js/jquery-1.4.4.min.js" ></script>
<title></title>
</head>
<style type="text/css">
body
{
background-color:#999999;
}
#myp
{
background-color:#FFFFFF;
width:250px;
height:250px;
display:none;
}
</style>
<body>
<input id="btn" type="button" value="显示p" />
<p id="myp">
This is a p;
</p>
</body>
<script type="text/javascript">
var myp = $("#myp");
$(function ()
{
$("#btn").click(function (event)
{
showp();//调用显示p方法
$(document).one("click", function ()
{//对document绑定一个影藏p方法
$(myp).hide();
});
event.stopPropagation();//阻止事件向上冒泡
});
$(myp).click(function (event)
{
event.stopPropagation();//阻止事件向上冒泡
});
});
function showp()
{
$(myp).fadeIn();
}
</script>The above is I compiled it for everyone, I hope it will be helpful to everyone in the future.
