jquery – replaceWith后不注册的事件

var replacement = $(document.createElement('span'));
var original = $(this).replaceWith(replacement);

replacement
    .css('BACkground-color','green')
    .text('replacement for ' + $(this).text())
    .click(function() {
        replacement.replaceWith(original);
    });

因为当您替换原始元素时，绑定到它的事件将被删除。调用replace.replaceWith(原始)后，您需要将click事件处理程序重新附加到原始文件：

$(function() 
{   
   function replace() 
   {
      var replacement = $(document.createElement('span'));
      var original = $(this).replaceWith(replacement);

      replacement
         .css('BACkground-color','green')
         .text('replacement for ' + $(this).text())
         .click(function() 
         {
            replacement.replaceWith(original);
            original.click(replacE);
         });
   }

   $('.x').click(replacE);
});
