1.利用pre標簽
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<style>
body{
padding-top: 20px;
}
#data_info{
width: 100%;
font-size: 16px;
white-space: pre-wrap;
word-wrap: break-word;
}
.string { color: green; }
.number { color: darkorange; }
.boolean { color: blue; }
.null { color: magenta; }
.key { color: red; }
</style>
</head>
<body>
<div id="content-container" class="container" style="margin: 0 auto; width: 90%;">
<pre id="data_info"></pre>
</div>
</body>
<script type="text/javascript">
var show = document.getElementById('data_info');
var jsondata = {"id": {"first":1, "second":2, "third":3, "fourth": [4, 5, 6, 7], "fifth": 5}, "name": {"ZS": "張三", "LS": "李四"}};
show.innerHTML = pretifyJson(jsondata,true);
/**
* [pretifyJson json格式化打印]
* @param {[type]} json [description]
* @param {Boolean} pretify [description]
* @return {[type]} [description]
*/
function pretifyJson(json, pretify=true) {
if (typeof json !== 'string') {
if(pretify){
json = JSON.stringify(json, undefined, 4);
}else{
json = JSON.stringify(json);
}
}
return json.replace(/("(\\u[a-zA-Z0-9]{4}|\\[^u]|[^\\"])*"(\s*:)?|\b(true|false|null)\b|-?\d+(?:\.\d*)?(?:[eE][+\-]?\d+)?)/g,
function (match) {
let cls = "<span>";
if (/^"/.test(match)) {
if (/:$/.test(match)) {
cls = "<span class='key'>";
} else {
cls = "<span class='string'>";
}
} else if (/true|false/.test(match)) {
cls = "<span class='boolean'>";
} else if (/null/.test(match)) {
cls = "<span class='null'>";
}
return cls + match + "</span>";
}
);
}
</script>
</html>
結果：
2.使用jsonview插件
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<link href="https://cdn.bootcdn.net/ajax/libs/jquery-jsonview/1.2.3/jquery.jsonview.css" rel="stylesheet">
<script type="text/javascript" src="https://code.jquery.com/jquery-2.1.1.min.js"></script>
<script type="text/javascript" src="https://cdn.bootcdn.net/ajax/libs/jquery-jsonview/1.2.3/jquery.jsonview.js"></script>
</head>
<body>
<div id="content-container" class="container" style="margin: 0 auto; width: 90%;">
<div id="data_info"></div>
</div>
</body>
<script type="text/javascript">
var jsondata = {"id": {"first":1, "second":2, "third":3, "fourth": [4, 5, 6, 7], "fifth": 5}, "name": {"ZS": "張三", "LS": "李四"}};
$(function() {
/* JSONView第一個參數就是需要轉換的json數據 */
$("#data_info").JSONView(jsondata, {collapsed: false, nl2br: true, recursive_collapser: true });
});
</script>
</html>
結果
