html页面展示json数据并格式化的方法

一、展现效果图

描述信息：

key值全部采用红色标出，表示重要参数；
value值采用不同颜色标出，数值类型的采用橘黄色，字符串采用绿色，布尔采用蓝色。。。

二、源代码展示

<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<style>
pre {outline: 1px solid #ccc; padding: 5px; margin: 5px; }
.string { color: green; }
.number { color: darkorange; }
.boolean { color: blue; }
.null { color: magenta; }
.key { color: red; }

.showinfo{
position: absolute;
background-color: #eef1f8;
width: 200px;
padding: 5px;
border-radius: 4px;
border: 1px solid #ccc;
display: none;
}
.showinfo pre{
padding: 5px;
border: 1px solid #ccc;
margin:0;
}
table,th,td{
border:1px solid blue;
}
</style>
<script src="./js/jquery-1.8.3.min.js"></script>
<script type="text/javascript">

$(document).ready(function(){
$(".show-rough").mouseover(function(){
var left = $(this).offset().left + $(this).width() +20;//计算div显示位置
var top = $(this).offset().top + 20;
var _jsonDate = $.parseJSON($(this).text());
var showJson = syntaxHighlight(_jsonDate);
$("#show-info").css({"left":left,"top":top}).show();
$("#show-pre").html(showJson);
});
$(".show-rough").mouseout(function(){
$("#show-info").hide().html();
$("#show-pre").html();
})
});
//处理json数据，采用正则过滤出不同类型参数
function syntaxHighlight(json) {
if (typeof json != \’string\’) {
json = JSON.stringify(json, undefined, 2);
}
json = json.replace(/&/g, \’&\’).replace(/</g, \'<\’).replace(/>/g, \’>\’);
return json.replace(/("(\\\\u[a-zA-Z0-9]{4}|\\\\[^u]|[^\\\\"])*"(\\s*:)?|\\b(true|false|null)\\b|-?\\d+(?:\\.\\d*)?(?:[eE][+\\-]?\\d+)?)/g, function(match) {
var cls = \’number\’;
if (/^"/.test(match)) {
if (/:$/.test(match)) {
cls = \’key\’;
} else {
cls = \’string\’;
}
} else if (/true|false/.test(match)) {
