Javascript 在真正的脚本上尝试时不起作用

这是我的工作小提琴：

我在下面的脚本中应用了相同的概念，但它不像在小提琴中那样给匹配的span文本上色。当我检查这些值是否传递给

colorMe（）

时，他们确实注销了：

    });//end forEach
    }

  });


});

/search/show_all_tutors.php

中的json格式数据如下：

[{"UUID":"5678f6c0b54da","morning":"","afternoon":"Thrs,Fri,Sat,Sun","evening":"Thrs,Fri,Sat,Sun"},{"UUID":"5678f6ef9fee1","morning":"Wed,Thrs","afternoon":"Wed,Thrs","evening":""}]

试一试

$（函数（）{
var数据；
$.ajax({
类型：“POST”，
数据类型：“json”，
url:“/search/show_all_tutors.php”，
数据：数据，
成功：功能（数据）{
data.forEach（函数（用户）{
$（“#contents”）.append（“+user.UUID+”Morning:mtwtfssaternoon:mtwtfsseving:MTWTFSS”）；
colorMe（user.morning、user.午后、user.nighter、user.UUID）；
})；//结束forEach
});

我觉得小提琴不适合我。所有的文字还是黑色的？@Joshua，对不起，这是最新的小提琴，

[{"UUID":"5678f6c0b54da","morning":"","afternoon":"Thrs,Fri,Sat,Sun","evening":"Thrs,Fri,Sat,Sun"},{"UUID":"5678f6ef9fee1","morning":"Wed,Thrs","afternoon":"Wed,Thrs","evening":""}]

$(function(){
    var data;
    $.ajax({
    type: "POST",
    dataType: "json",
    url: "/search/show_all_tutors.php", 
    data: data,
    success: function(data) {

        data.forEach(function(user){

           $("#contents").append("<div>"+user.UUID+"</div><div class='morning_"+user.UUID+"'>Morning: <span class='Mon'>M</span><span class='Tue'>T</span><span class='Wed'>W</span><span class='Thrs'>T</span><span class='Fri'>F</span><span class='Sat'>S</span><span class='Sun'>S</span></div><div class='afternoon_"+user.UUID+"'>Afternoon: <span class='Mon'>M</span><span class='Tue'>T</span><span class='Wed'>W</span><span class='Thrs'>T</span><span class='Fri'>F</span><span class='Sat'>S</span><span class='Sun'>S</span></div><div class='evening_"+user.UUID+"'>Evening: <span class='Mon'>M</span><span class='Tue'>T</span><span class='Wed'>W</span><span class='Thrs'>T</span><span class='Fri'>F</span><span class='Sat'>S</span><span class='Sun'>S</span></div>");  

           colorMe(user.morning, user.afternoon, user.evening, user.UUID);
