本文主要和大家分享js格式化json的实例代码,希望能帮助到大家。
var jsonStr;// json字符串
// 格式化json字符串 var jsonFormat = formatJson(jsonStr);
// 工具方法 var formatJson = function(json, options) { var reg = null, formatted = '', pad = 0, PADDING = ' '; // one can also use '\t' or a different number of spaces // optional settings options = options || {}; // remove newline where '{' or '[' follows ':' options.newlineAfterColonIfBeforeBraceOrBracket = (options.newlineAfterColonIfBeforeBraceOrBracket === true) ? true : false; // use a space after a colon options.spaceAfterColon = (options.spaceAfterColon === false) ? false : true; // begin formatting... // make sure we start with the JSON as a string if (typeof json !== 'string') { json = JSON.stringify(json); } // parse and stringify in order to remove extra whitespace json = JSON.parse(json); json = JSON.stringify(json); // add newline before and after curly braces reg = /([\{\}])/g; json = json.replace(reg, '\r\n$1\r\n'); // add newline before and after square brackets reg = /([\[\]])/g; json = json.replace(reg, '\r\n$1\r\n'); // add newline after comma reg = /(\,)/g; json = json.replace(reg, '$1\r\n'); // remove multiple newlines reg = /(\r\n\r\n)/g; json = json.replace(reg, '\r\n'); // remove newlines before commas reg = /\r\n\,/g; json = json.replace(reg, ','); // optional formatting... if (!options.newlineAfterColonIfBeforeBraceOrBracket) { reg = /\:\r\n\{/g; json = json.replace(reg, ':{'); reg = /\:\r\n\[/g; json = json.replace(reg, ':['); } if (options.spaceAfterColon) { reg = /\:/g; json = json.replace(reg, ': '); } $.each(json.split('\r\n'), function(index, node) { var i = 0, indent = 0, padding = ''; if (node.match(/\{$/) || node.match(/\[$/)) { indent = 1; } else if (node.match(/\}/) || node.match(/\]/)) { if (pad !== 0) { pad -= 1; } } else { indent = 0; } for (i = 0; i <h2 id="效果图">效果图</h2><p><img src="/static/imghwm/default1.png" data-src="https://img.php.cn/upload/article/000/054/025/e7a0d111808dbab136d1b241dd6a4a37-0.png?x-oss-process=image/resize,p_40" class="lazy" alt=""></p><p>相关推荐:</p><p><a href="http://www.php.cn/div-tutorial-385071.html" target="_self" textvalue="html怎样格式化json数据">html怎样格式化json数据</a></p><p><a href="http://www.php.cn/js-tutorial-380221.html" target="_self">格式化Json传递日期的方法</a></p><p><a href="http://www.php.cn/html5-tutorial-363244.html" target="_self">html格式化json的实例代码</a></p>
