您可以看到一个简单的代码：

＆＃13;

  var json = '{"data":[{"SNo":"1","StudentName":"YASHAA BANERJEE","AdmissionNo":"01F7001","Subject":"Science","Class":"1"}]}'
json = JSON.parse(json);

var tb = $("#tab");

$.each(json.data,function(i,value){
  tb.append("<tr><td>SNo: " + value.SNo + "</td><td>StudentName: " + value.StudentName + "</td><td>AdmissionNo: " + value.AdmissionNo + "</td><td>Subject: " + value.Subject + "</td><td>Class: " + value.Class + "</td></tr>");
});

＆＃13;

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<table id="tab">
  
<table>

＆＃13;

如何在html文件上获取json数据？
