js富文本处理和表单提交功能实例详解

function decodeHtml(s) { var HTML_DECODE = { "<": "<", ">": ">", "&": "&", " ": " ", """: "\"", "©": "" // Add more }; var REGX_HTML_ENCODE = /"|&|'|<|>|[\x00-\x20]|[\x7F-\xFF]|[\u0100-\u2700]/g; var REGX_HTML_DECODE = /&\w+;|&#(\d+);/g; var REGX_TRIM = /(^\s*)|(\s*$)/g; s = (s != undefined) ? s : ""; return (typeof s != "string") ? s : s.replace(REGX_HTML_DECODE, function ($0, $1) { var c = HTML_DECODE[$0]; if (c == undefined) { // Maybe is Entity Number if (!isNaN($1)) { c = String.fromCharCode(($1 == 160) ? 32 : $1); } else { c = $0; } } return c; }); }; $(document).ready(function(){ var content= "{{$data['content']}}"; $("#content").append(decodeHtml(content)); });

//获取表单的所有数据 var form_data = $('#From_id_2').serializeArray(); var m = [], idata; $.each(form_data, function (i, field) { m.push('"' + field.name + '":"' + encodeURI(field.value) + '"'); }); idata = '{' + m.join(',') + '}'; // 按字符 idata 转换成 JSON 格式 idata = eval('(' + idata + ')'); console.log(idata); //表单的所有数据,可以直接提交到后台
