將 json 數據以美觀的縮進格式顯示出來,藉助最簡單的 JSON.stringify 函數就能夠了,由於此函數還有不經常使用的後面2個參數。javascript
見MDN https://developer.mozilla.org/zh-CN/docs/Web/JavaScript/Reference/Global_Objects/JSON/stringify 的描述。html
示例代碼以下:java
<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"> </pre> <script type="text/javascript"> var songResJson={ "service": "ALL", "qt": 581, "content": { "answer": { "song": "若是緣只到碰見", "album": "若是緣只到碰見", "artist": "吳奇隆 嚴藝丹", "pic_url": "http://p1.music.126.net/-u3WgIXsFNCW7d8Jy7pCEA==/5921969627395387.jpg" }, "scene": "music" } } document.getElementById('result').innerHTML = syntaxHighlight(songResJson); // $('#result').html(syntaxHighlight(songResJson)); </script> </body> </html>
