javascript - 5 秒后删除内容表单标签

Question

在我获取数据并将它们设置到标签中后，5秒后我想清除这个标签。我尝试:

$('#ajax_message').html(data).delay(5000).html("");

但这不起作用。我怎样才能做到这一点？

Answer 1

根据文档:

jQuery.delay() is best for delaying between queued jQuery effects and such, and is not a replacement for JavaScript's native setTimeout function, which may be more appropriate for certain use cases.

长话短说，.delay() 适用于 queued functions 。您应该使用 setTimeout() 来代替。

$('#ajax_message').html(data)
setTimeout(function(){
  $('#ajax_message').html("");
},5000);
