javascript - 使用 Ajax 传递解析 JSON 值时出错

Question

这是我的 Ajax 调用

<script>
$.ajax({
        url:"http://localhost:3000/house/get-all",
        type: "GET",
        dataType: 'json',
        data,    
        crossDomain: "true",      

      }
      });
</script>

这是我的 html 代码:

<div id="houses">
This is place to put content. You can put slider, short description about your website and place some links for navigation.
</p>
</div>

错误:

Uncaught ReferenceError: data is not defined

Answer 1

如果您没有在 ajax 选项中传递任何数据，则不需要数据:

$.ajax({
    url:"http://localhost:3000/house/get-all",
    type: "GET",
    dataType: 'json',
    // data, -- remove this or pass something here
    // ...
});
