Question

我的表格数据存储在名为test_array.txt的文本文件中

[
{id:1, name:"Oli Bob", age:"12", col:"red", dob:""},
{id:2, name:"Mary May", age:"1", col:"blue", dob:"14/05/1982"},
{id:3, name:"Christine Lobowski", age:"42", col:"green", dob:"22/05/1982"},
{id:4, name:"Brendon Philips", age:"125", col:"orange", dob:"01/08/1980"},
{id:5, name:"Margret Marmajuke", age:"16", col:"yellow", dob:"31/01/1999"},
];

setData时如何调用文本文件。我在下面尝试过，并且表结构已构建，但是数据未加载，但表中显示错误。

       //load sample data into the table
    table.setData("../textfiles/test_array.txt");

在我的浏览器控制台中，收到以下错误消息。

Ajax加载错误：语法错误：“ JSON.parse：JSON数据的第2行第2列的预期属性名称或'}'”

这是我的整个剧本

Answer 1

我使用按键上的双引号使它起作用

[
{"name":"Oli Bob", "age":"12", "col":"red", "dob":""},
{"name":"Mary May", "age":"1", "col":"blue", "dob":"14/05/1982"},
{"name":"Christine Lobowski", "age":"42", "col":"green", "dob":"22/05/1982"},
{"name":"Brendon Philips", "age":"125", "col":"orange", "dob":"01/08/1980"},
{"name":"Margret Marmajuke", "age":"16", "col":"yellow", "dob":"31/01/1999"}
]

Answer 2

您在代码的第6行上有一个无效的结尾逗号，id为5的行的末尾不应带有逗号，并且在数组后也不需要分号，它是无效的JSON。应该是：

[
{id:1, name:"Oli Bob", age:"12", col:"red", dob:""},
{id:2, name:"Mary May", age:"1", col:"blue", dob:"14/05/1982"},
{id:3, name:"Christine Lobowski", age:"42", col:"green", dob:"22/05/1982"},
{id:4, name:"Brendon Philips", age:"125", col:"orange", dob:"01/08/1980"},
{id:5, name:"Margret Marmajuke", age:"16", col:"yellow", dob:"31/01/1999"}
]

您是否已在浏览器网络开发人员工具中检查了响应，这是什么？您的服务器也可能未返回您期望的文件，签入网络工具应该可以让您确认返回的信息
