JSONView介绍
jQuery插件，用于显示漂亮的JSON。
官网地址：https://plugins.jquery.com/jsonview/
git地址：https://github.com/yesmeck/jquery-jsonview
JSONView使用
1、下载jsonview插件
2、在html中引入插件
<link rel="stylesheet" href="jquery.jsonview.css" />
<script type="text/javascript" src="http://code.jquery.com/jquery.min.js"></script>
<script type="text/javascript" src="jquery.jsonview.js"></script>
3、js中调用（本例对js做了修改，多引入了2个选项：key_marks、link_marks）
<script type="text/javascript">
var json = {
"he<y": "guy",
"anumber": 243,
"anobject": {
"whoa": "nuts",
"anarray": [1, 2, "thr<h1>ee"],
"more":"stuff"
},
"awesome": true,
"bogus": false,
"meaning": null,
"japanese":"明日がある。",
"link": "http://jsonview.com",
"notLink": "http://jsonview.com is great",
"multiline": ['Much like me, you make your way forward,',
'Walking with downturned eyes.',
'Well, I too kept mine lowered.',
'Passer-by, stop here, please.'].join("\n")
};
$(function() {
$("#json").JSONView(json); /*
collapsed：是否在第一次渲染时收缩所有的节点，默认值为：false。
nl2br：是否将一个新行转换为<br>字符串，默认值为false。
recursive_collapser：是否递归收缩节点，默认值为false。
key_marks:是否为key添加双引号，默认值为false。
link_marks:是否为连接添加双引号，默认值为false。
*/
$("#json-collapsed").JSONView(json, { collapsed: true, nl2br: true, recursive_collapser: true, key_marks: true, link_marks: true }); $('#collapse-btn').on('click', function() {
$('#json').JSONView('collapse');
}); $('#expand-btn').on('click', function() {
$('#json').JSONView('expand');
}); $('#toggle-btn').on('click', function() {
$('#json').JSONView('toggle');
}); $('#toggle-level1-btn').on('click', function() {
$('#json').JSONView('toggle', 1);
}); $('#toggle-level2-btn').on('click', function() {
$('#json').JSONView('toggle', 2);
});
});
</script>
具体html，js，css文件如下：
<!DOCTYPE HTML>
<html lang="en">

<meta charset="UTF-8">

<script type="text/javascript" src="jquery.jsonview.js"></script>
<script type="text/javascript">
var json = {
"he<y": "guy",
"anumber": 243,
"anobject": {
"whoa": "nuts",
"anarray": [1, 2, "thr<h1>ee"],
"more":"stuff"
},
"awesome": true,
"bogus": false,
"meaning": null,
"japanese":"明日がある。",
"link": "http://jsonview.com",
"notLink": "http://jsonview.com is great",
"multiline": ['Much like me, you make your way forward,',
'Walking with downturned eyes.',
'Well, I too kept mine lowered.',
'Passer-by, stop here, please.'].join("\n")
};
$(function() {
$("#json").JSONView(json); /*

nl2br：是否将一个新行转换为<br>字符串，默认值为false。
recursive_collapser：是否递归收缩节点，默认值为false。

link_marks:是否为连接添加双引号，默认值为false。
*/
$("#json-collapsed").JSONView(json, { collapsed: true, nl2br: true, recursive_collapser: true, key_marks: true, link_marks: true }); $('#collapse-btn').on('click', function() {
$('#json').JSONView('collapse');
