本篇文章主要介绍了html格式化输出JSON示例(测试接口) ，小编觉得挺不错的，现在分享给大家，也给大家做个参考。一起跟随小编过来看看吧
将 json 数据以美观的缩进格式显示出来，借助最简单的 JSON.stringify 函数就可以了，因为此函数还有不常用的后面2个参数。
见MDN https://developer.mozilla.org/zh-CN/docs/Web/JavaScript/Reference/Global_Objects/JSON/stringify 的描述。
示例代码如下：
<html>
<head>
<meta charset="utf-8" />
<title>hello</title>
<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; }
</style>
<script type="text/javascript">
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)) {
cls = 'boolean';
} else if (/null/.test(match)) {
cls = 'null';
}
return '<span class="' + cls + '">' + match + '</span>';
});
}
</script>
</head>
<body>
<pre id="result">
<script>
var songResJson={
"service": "ALL",
"qt": 581,
"content": {
"answer": {
"song": "如果缘只到遇见",
"album": "如果缘只到遇见",
"artist": "吴奇隆 严艺丹",
"pic_url": "http://p1.music.126.net/-u3WgIXsFNCW7d8Jy7pCEA==/5921969627395387.jpg"
},
"scene": "music"
}
}
document.getElementById('result').innerHTML = syntaxHighlight(songResJson);
// $('#result').html(syntaxHighlight(songResJson));
</script>
The above is the detailed content of html formatted output JSON. For more information, please follow other related articles on the PHP Chinese website!
