javascript - 打印 JavaScript 响应

Question

我有一个 php 脚本，可以响应正在上传的文件。我想“回应”这个回复，但我无法让它发挥作用

正如您在下面的脚本中看到的，我使用了“响应”，因为我想不出任何东西。这是如何工作的？

success:function(response){
    if(response == 6563){
        var uploaddiv = document.getElementById('uploadattachment');
        uploaddiv.innerHTML = '<center><br><br><span style="font-size:18px; color:green;">File has successfully been uploaded.</span><br>You can now click this window away or upload another file</center>';
    } else {
        var uploaddiv = document.getElementById('uploadattachment');
        uploaddiv.innerHTML = '<center><br><br><span style="font-size:18px; color:red;">Oops, something went wrong</span><br>' response '</center>';
    }

Answer 1

您忘记正确连接字符串(缺少“+”):

uploaddiv.innerHTML = '<center><br><br><span style="font-size:18px; color:red;">Oops, something went wrong</span><br>'+response+'</center>';
