标签： javascript html css button fade

所以基本上我有一个按钮，当用户点击它时，一个div淡入。我希望当用户点击div上的任何地方时它会淡出。 （div占据了整个屏幕）

这是我到目前为止所做的，当你点击＆＃34;关于＆＃34;它基本上只是在div中消失。按钮。每当我点击屏幕上的任何地方时，我都需要它淡出。

为刚刚淡入的正文内容添加一个点击监听器，然后将其淡出！

＆＃13;
＆＃13; 
$(function() {
  
  $('#fadeContent').click(function(){
    var bodyContent = $('#bodyContent')
    bodyContent.fadeIn(500);
    bodyContent.click(function() {
      $(this).fadeOut(500);
    })

当您致电fadeOut时，只需将fadeIn连接到点击事件中。

$('#fadeContent').click(function(){
    $('#bodyContent').click(function() { 
       $(this).fadeOut(500); 
    }).fadeIn(500);
});

修改

上面的代码将在每次单击按钮时保持连接事件处理程序。假设所有按钮都将加载并显示内容并单击内容应始终返回按钮考虑; 

var $content = $('#bodyContent');
$('body').on('click','button', function() {
    $content.fadeIn(500);
});
$content.on('click', function() {
   $content.fadeOut(500);
});

然后，您可以为各个按钮附加点击事件，以便检索并将特定内容分配到#bodyContent，而无需挂钩fadeIn / fadeOut。
