    L的输出：

    这里是使用console.log（my\u var4）时my\u var4变量的输出。

    如果我把它分开，我会得到一个物体。但我想要一个数组。如何在此处转换此数据类型。或者我需要采用其他方法吗？

    Hi，当您收到一个作为json对象的字符串构建时，您是否尝试过解析它？你能试试
    JSON.parse（“{responseList}”）
    我试过了：我得到了这个错误：“uncaughtsyntaxerror:untaughttoken{在JSON中的位置1”@RahulAnand没有帮助。请提供更多信息进行调试。你能打印
    my_var
    console.log（my_var）的控制台输出吗
    ？在my_var变量声明之后？@RajaSimon编辑问题，输出console.log（my_var） 
           <script>
var my_var = "{{ responseList }}";
var my_var2 = "{{ jsonStr }}";
var my_var3 = "{{ sentimentlist }}";
var my_var4 = "{{ jsonStr1 }}";
var my_var5 = "{{ e }}";

</script>

        function decodeHtml(html) {
    var txt = document.createElement("textarea");
    txt.innerHTML = html;
    return txt.value;
}
//console.log(my_var4);
L=decodeHtml(my_var4);
console.log(typeof(L))
values = L.split(",/s")
console.log(values)
console.log(typeof(values))
