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
});

当前回答
只是一个警告,使用这个:
$('html').click(function() {
// Hide the menus if visible
});
$('#menucontainer').click(function(event){
event.stopPropagation();
});
它阻止RubyonRails UJS驱动程序正常工作。例如,link_to“click”、“/url”、:method=>:delete将不起作用。
这可能是一种变通方法:
$('html').click(function() {
// Hide the menus if visible
});
$('#menucontainer').click(function(event){
if (!$(event.target).data('method')) {
event.stopPropagation();
}
});
其他回答
这是我的代码:
// Listen to every click
$('html').click(function(event) {
if ( $('#mypopupmenu').is(':visible') ) {
if (event.target.id != 'click_this_to_show_mypopupmenu') {
$('#mypopupmenu').hide();
}
}
});
// Listen to selector's clicks
$('#click_this_to_show_mypopupmenu').click(function() {
// If the menu is visible, and you clicked the selector again we need to hide
if ( $('#mypopupmenu').is(':visible') {
$('#mypopupmenu').hide();
return true;
}
// Else we need to show the popup menu
$('#mypopupmenu').show();
});
标准HTML:
用<标签>包围菜单并获取焦点状态更改。

另外:您可以通过Tab展开菜单。
解决方案1
不要使用event.stopPropagation(),因为它会产生一些副作用,只需定义一个简单的标志变量并添加一个if条件。我对此进行了测试,工作正常,没有任何stopPropagation的副作用:
var flag = "1";
$('#menucontainer').click(function(event){
flag = "0"; // flag 0 means click happened in the area where we should not do any action
});
$('html').click(function() {
if(flag != "0"){
// Hide the menus if visible
}
else {
flag = "1";
}
});
解决方案2
只有一个简单的if条件:
$(document).on('click', function(event){
var container = $("#menucontainer");
if (!container.is(event.target) && // If the target of the click isn't the container...
container.has(event.target).length === 0) // ... nor a descendant of the container
{
// Do whatever you want to do when click is outside the element
}
});
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));
根据此答案改编https://stackoverflow.com/a/3028037/1611058
<div class="feedbackCont" onblur="hidefeedback();">
<div class="feedbackb" onclick="showfeedback();" ></div>
<div class="feedbackhide" tabindex="1"> </div>
</div>
function hidefeedback(){
$j(".feedbackhide").hide();
}
function showfeedback(){
$j(".feedbackhide").show();
$j(".feedbackCont").attr("tabindex",1).focus();
}
这是我想出的最简单的解决方案。
