DOM case sharing—jQ realizes the effect of clicking anywhere to close a certain place
Practical combat of DOM in Javascript learning, jQ realizes the effect of clicking anywhere to close a certain place (often used in the mask layer behind the modal box)
Click anywhere Closing a certain place
and clicking the corresponding place will not hide yourself
Principle
//点击文档任意处都触发该事件$(document).mousedown(function(e){
//只有当某对象存在时才会有的点击任意处出现的事件效果
if($(e.target).parents(".search").length==0){
$("xxx").slideToggle(300);//显示隐藏
}
})I took out some of the following web pages in practice, so the final style may be different.
The idea is
//点击文档任意处都触发该事件$(document).mousedown(function(e){
if(想要显示的对象如果是在显示状态时才有以下的触发效果){ //只有当某对象存在时才会有的点击任意处出现的事件效果
if($(e.target).parents(".search").length==0){
$("xxx").slideToggle(300);//显示隐藏
}
}
})Effect

Many times, ref is clearly used to bind related components, but ref binding often fails. Examples of ref binding failure situations The vast majority of cases where ref binding fails is that when the ref is bound to the component, the component has not yet been rendered, so the binding fails.
