最近开发中需要在页面展示json。特整理了下代码,送给大家,希望能帮到有同样需求的朋友们。
代码:
<html> <script src="http://cdn.bootcss.com/jquery/3.0.0-rc1/jquery.min.js"></script> <body> <span class="result"></span> <script> //json格式化方法 参数1:json对象,参数2:缩进字符数 var JSONFormat = (function(){ var _toString = Object.prototype.toString; function format(object, indent_count){ var html_fragment = ‘‘; switch(_typeof(object)){ case ‘Null‘ :0 html_fragment = _format_null(object); break; case ‘Boolean‘ : html_fragment = _format_boolean(object); break; case ‘Number‘ : html_fragment = _format_number(object); break; case ‘String‘ : html_fragment = _format_string(object); break; case ‘Array‘ : html_fragment = _format_array(object, indent_count); break; case ‘Object‘ : html_fragment = _format_object(object, indent_count); break; } return html_fragment; }; function _format_null(object){ return ‘<span class="json_null">null</span>‘; } function _format_boolean(object){ return ‘<span class="json_boolean">‘ + object + ‘</span>‘; } function _format_number(object){ return ‘<span class="json_number">‘ + object + ‘</span>‘; } function _format_string(object){ object = object.replace(/</g,"<"); object = object.replace(/>/g,">"); if(0 <= object.search(/^http/)){ object = ‘<a href="‘ + object + ‘" target="_blank" class="json_link">‘ + object + ‘</a>‘ } return ‘<span class="json_string">"‘ + object + ‘"</span>‘; } function _format_array(object, indent_count){ var tmp_array = []; for(var i = 0, size = object.length; i < size; ++i){ tmp_array.push(indent_tab(indent_count) + format(object[i], indent_count + 1)); } return ‘<span data-type="array" data-size="‘ + tmp_array.length + ‘"><i style="cursor:pointer;" class="fa fa-minus-square-o" onclick="hide(this)"></i>[<br/>‘ + tmp_array.join(‘,<br/>‘) + ‘<br/>‘ + indent_tab(indent_count - 1) + ‘]</span>‘; } function _format_object(object, indent_count){ var tmp_array = []; for(var key in object){ tmp_array.push( indent_tab(indent_count) + ‘<span class="json_key">"‘ + key + ‘"</span>:‘ + format(object[key], indent_count + 1)); } return ‘<span data-type="object"><i style="cursor:pointer;" class="fa fa-minus-square-o" onclick="hide(this)"></i>{<br/>‘ + tmp_array.join(‘,<br/>‘) + ‘<br/>‘ + indent_tab(indent_count - 1) + ‘}</span>‘; } function indent_tab(indent_count){ return (new Array(indent_count + 1)).join(‘ ‘); } function _typeof(object){ var tf = typeof object, ts = _toString.call(object); return null === object ? ‘Null‘ : ‘undefined‘ == tf ? ‘Undefined‘ : ‘boolean‘ == tf ? ‘Boolean‘ : ‘number‘ == tf ? ‘Number‘ : ‘string‘ == tf ? ‘String‘ : ‘[object Function]‘ == ts ? ‘Function‘ : ‘[object Array]‘ == ts ? ‘Array‘ : ‘[object Date]‘ == ts ? ‘Date‘ : ‘Object‘; }; function loadCssString(){ var style = document.createElement(‘style‘); style.type = ‘text/css‘; var code = Array.prototype.slice.apply(arguments).join(‘‘); try{ style.appendChild(document.createTextNode(code)); }catch(ex){ style.styleSheet.cssText = code; } document.getElementsByTagName(‘head‘)[0].appendChild(style); } loadCssString( ‘.json_key{ color: #92278f;font-weight:bold;}‘, ‘.json_null{color: #f1592a;font-weight:bold;}‘, ‘.json_string{ color: #3ab54a;font-weight:bold;}‘, ‘.json_number{ color: #25aae2;font-weight:bold;}‘, ‘.json_link{ color: #717171;font-weight:bold;}‘, ‘.json_array_brackets{}‘); var _JSONFormat = function(origin_data){ this.data = JSON.parse(origin_data); }; _JSONFormat.prototype = { constructor : JSONFormat, toString : function(){ return format(this.data, 1); } } return _JSONFormat; })(); //json案例 var demoJson = { "A1": "a1", "A11": "a11", "A111_next": [ { "B1": "b1", "B11": "b11", "B111_next": [ { "C1": "c1", "C11": "c11", "C111_next": [] } ] }, { "B2": "b2", "B22": "b22", "B222_next": [] } ] } //将格式化好的json显示到前台页面 function showJson(demoJson) { var result = new JSONFormat(JSON.stringify(demoJson),4).toString() $(‘.result‘).html(result); } showJson(demoJson); </script> </body> </html>
