JavaScript的URL encode decode源代码，ip验证，TRim
使用JavaScript对数据进行编码和解码动作，代码如下：
<script type="text/javascript">var Url = { // public method for url encodingencode : function (string) {return escape(this._utf8_encode(string));}, // public method for url decodingdecode : function (string) {return this._utf8_decode(unescape(string));}, // private method for UTF-8 encoding_utf8_encode : function (string) {string = string.replace(/\r\n/g,"\n");var utftext = ""; for (var n = 0; n < string.length; n++) { var c = string.charCodeAt(n); if (c < 128) {utftext += String.fromCharCode(c);}else if((c > 127) && (c < 2048)) {utftext += String.fromCharCode((c >> 6) | 192);utftext += String.fromCharCode((c & 63) | 128);}else {utftext += String.fromCharCode((c >> 12) | 224);utftext += String.fromCharCode(((c >> 6) & 63) | 128);utftext += String.fromCharCode((c & 63) | 128);} } return utftext;}, // private method for UTF-8 decoding_utf8_decode : function (utftext) {var string = "";var i = 0;var c = c1 = c2 = 0; while ( i < utftext.length ) { c = utftext.charCodeAt(i); if (c < 128) {string += String.fromCharCode(c);i++;}else if((c > 191) && (c < 224)) {c2 = utftext.charCodeAt(i+1);string += String.fromCharCode(((c & 31) << 6) | (c2 & 63));i += 2;}else {c2 = utftext.charCodeAt(i+1);c3 = utftext.charCodeAt(i+2);string += String.fromCharCode(((c & 15) << 12) | ((c2 & 63) << 6) | (c3 & 63));i += 3;} } return string;} }var sss = "aaa.html?new=1&time[0][0]=+&time[0][1]=%3E%3D&time[0][2]=12&time[0][3]=29&time[0][4]=2010&time[0][5]=&time[0][6]=&time[0][7]=&time[0][8]=+&time[0][9]=+&submit=Query+DB&num_result_rows=-1&time_cnt=1";alert(Url.decode(sss));//alert(sss.replace("&","&","ig"));//alert(Url.decode(sss.replace("&","&","ig")));</script>?IP 验证代码
String.prototype.isIP = function(){ var reSpaceCheck = /^([0-9]{1,3})\.([0-9]{1,3})\.([0-9]{1,3})\.([0-9]{1,3})$/i; if (reSpaceCheck.test(this)){ this.match(reSpaceCheck); if (RegExp.$1 <= 255 && RegExp.$1 > 0 && RegExp.$2 <= 255 && RegExp.$2 >= 0 && RegExp.$3 <= 255 && RegExp.$3 >= 0 && RegExp.$4 <= 255 && RegExp.$4 >= 0) { return true; } else { return false; } } else { return false; }}var strip = "0.0.5.194";alert(strip.isIP());?String.Trim代码
String.prototype.Trim = function() { return this.replace(/(^\s*)|(\s*$)/g, "");} String.prototype.LTrim = function() { return this.replace(/(^\s*)/g, ""); } String.prototype.RTrim = function() { return this.replace(/(\s*$)/g, ""); } ?上面的个代码的各个例子在附件中
