This time I will bring you jquery to read json data and use it in html. jquery to read json data and use it in html. What are the precautions?The following is a practical case. Let’s take a look. one time.
JSON format
json is the most frequently used data format in Ajax, and communication between the browser and the server is inseparable from it.
JSON format description
It is important to note that attribute names in JSON need to be enclosed in quotes.
1. Download and install jquery
The online version of js can be introduced through the following method:
<script src="https://apps.bdimg.com/libs/jquery/2.1.4/jquery.min.js"></script>
Refer to the installation documentation: http://www.jb51.net/zt/jquerydown.htm
2. Prepare a file in json format, the suffix may not be .json
For example, the following is the format of result.json
{
"title":"【UI测试结果】-转转2017/1/23 14:47",
"starttime":"2017/1/23 15:00 45",
"endtime":"2017/1/23 15:01 42",
"passcount":10,
"failurecount":5,
"resultinfo":[
{
"name":"发布",
"moudle":"Publish",
"pass":"true",
"onecepass":"true",
"log":"true"
},
{
"name":"登录",
"moudle":"Login",
"pass":"false",
"onecepass":"true",
"log":"asserterrorlog",
"failurereason":{
"errorlog":"asserterror",
"errorimg":"./登录.jpg"
}
}
]
}3. Obtain the data of the Json file through $.getJSON
For example, the following example: read the contents of the result.json file and store it in the result variable. The result is a json format
$.getJSON('./result.json',function(result){}4. Add the html content behind the positioned element through [$('#element id').after(html content);]
Element positioning method
$("#id")：定位到id，
$(“p")：定位到标签p，其他标签同理
$(“.class”)：定位到classInsert html content location:
append() - Insert content at the end of the selected element
Json data operations
JSON object [key] to read the content: result['title'], or use result."title"
The object value of the array can be obtained through $.each:
$.each(JSON array object, function(traversal index i, traversal object){operating the traversed object})
The code to read result.json and append html is as follows
(jquery needs to be written in the <script> tag)</strong></p>
<div class="code" style="position:relative; padding:0px; margin:0px;"><pre class="brush:php;toolbar:false"><!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<HTML>
<HEAD>
<TITLE> New Document </TITLE>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<script src="https://apps.bdimg.com/libs/jquery/2.1.4/jquery.min.js"></script>
<script>
$(document).ready(function(){
//使用getJSON方法读取json数据,
//注意：info.json可以是不同类型文件，只要其中的数据为json类型即可
$.getJSON('./result.json',function(result){
var html_title='';
var html_resultinfo='';
html_title += '<b>'+result["title"]+'</b>';
$('#resultitle').after(html_title);
$.each(result["resultinfo"],function(i,item){
if(item["pass"]=="true") {
html_resultinfo += '<tr><td>' + item['name'] + '</td>' +
'<td>' + item['moudle'] + '</td>' +
'<td>' + item["pass"] + '</td>' +
'<td>' + item['onecepass'] + '</td>' +
'<td id="' + item['moudle'] + '" class="collapsed" onclick="collapsedisplay(' + item['moudle'] + ')"><u style="color: blue;">展开</u></td></tr>';
html_resultinfo +='<tr id="' + item['moudle'] + 'info" class="collapsedinfo" style="display:none"><td colspan="5">' + item['log'] + '</td></tr>';
}
$('#infotitle').after(html_resultinfo);//after方法:在每个匹配的元素之后插入内容。
});
});
</script>
