我有一些HTML菜单,当用户单击这些菜单的头部时,我会完全显示这些菜单。当用户在菜单区域外单击时,我希望隐藏这些元素。
jQuery是否可以实现这样的功能?
$("#menuscontainer").clickOutsideThisElement(function() {
// Hide the menus
});

外部点击插件!
用法:
$('.target-element').outsideClick(function(event){
//code that fires when user clicks outside the element
//event = the click event
//$(this) = the '.target-element' that is firing this function
}, '.excluded-element')
它的代码:
(function($) {
//when the user hits the escape key, it will trigger all outsideClick functions
$(document).on("keyup", function (e) {
if (e.which == 27) $('body').click(); //escape key
});
//The actual plugin
$.fn.outsideClick = function(callback, exclusions) {
var subject = this;
//test if exclusions have been set
var hasExclusions = typeof exclusions !== 'undefined';
//switches click event with touch event if on a touch device
var ClickOrTouchEvent = "ontouchend" in document ? "touchend" : "click";
$('body').on(ClickOrTouchEvent, function(event) {
//click target does not contain subject as a parent
var clickedOutside = !$(event.target).closest(subject).length;
//click target was on one of the excluded elements
var clickedExclusion = $(event.target).closest(exclusions).length;
var testSuccessful;
if (hasExclusions) {
testSuccessful = clickedOutside && !clickedExclusion;
} else {
testSuccessful = clickedOutside;
}
if(testSuccessful) {
callback.call(subject, event);
}
});
return this;
};
}(jQuery));

简单插件:
$.fn.clickOff = function(callback, selfDestroy) {
var clicked = false;
var parent = this;
var destroy = selfDestroy || true;
parent.click(function() {
clicked = true;
});
$(document).click(function(event) {
if (!clicked && parent.is(':visible')) {
if(callback) callback.call(parent, event)
}
if (destroy) {
//parent.clickOff = function() {};
//parent.off("click");
//$(document).off("click");
parent.off("clickOff");
}
clicked = false;
});
};
Use:
$("#myDiv").clickOff(function() {
alert('clickOff');
});
这种情况的简单解决方案是:
$(document).mouseup(function (e)
{
var container = $("YOUR SELECTOR"); // Give you class or ID
if (!container.is(e.target) && // If the target of the click is not the desired div or section
container.has(e.target).length === 0) // ... nor a descendant-child of the container
{
container.hide();
}
});
如果在div单击事件之外触发,上述脚本将隐藏div。
这是一个容器或整个文档中的解决方案。若click目标在元素之外(类为“yourClass”),则元素被隐藏。
$('yourContainer').on('click', function(e) {
if (!$(e.target).hasClass('yourClass')) {
$('.yourClass').hide();
}
});
我已经使用了下面的脚本并完成了jQuery。
jQuery(document).click(function(e) {
var target = e.target; //target div recorded
if (!jQuery(target).is('#tobehide') ) {
jQuery(this).fadeOut(); //if the click element is not the above id will hide
}
})
下面是HTML代码
<div class="main-container">
<div> Hello I am the title</div>
<div class="tobehide">I will hide when you click outside of me</div>
</div>

这对我有用
$("body").mouseup(function(e) {
var subject = $(".main-menu");
if(e.target.id != subject.attr('id') && !subject.has(e.target).length) {
$('.sub-menu').hide();
}
});
