思想：
/main.jsp 替换成 info/info.jsp
var URL = function(param){ if(typeof param=="undefined"){ throw new Error("你需要传入一个param作为参数"); } this.urlname=param; } URL.prototype = { constructor:URL, subUrl:function(filepath,filename){ var newvalue = filepath+"/"+filename;//info/info.jsp var searchvalue = this.parseURL(this.urlname).file; console.log(newvalue); console.log(searchvalue); var Str = this.urlname; this.urlname = Str.replace(searchvalue,newvalue) return this.urlname; }, parseURL:function parseURL(url) { var a = document.createElement('a'); a.href = url; return { source: url, protocol: a.protocol.replace(':',''), host: a.hostname, port: a.port, query: a.search, params: (function(){ var ret = {}, seg = a.search.replace(/^\?/,'').split('&'), len = seg.length, i = 0, s; for (;i<len;i++) { if (!seg[i]) { continue; } s = seg[i].split('='); ret[s[0]] = s[1]; } return ret; })(), file: (a.pathname.match(/\/([^\/?#]+)$/i) || [,''])[1], hash: a.hash.replace('#',''), path: a.pathname.replace(/^([^\/])/,'/$1'), relative: (a.href.match(/tps?:\/\/[^\/]+(.+)/) || [,''])[1], segments: a.pathname.replace(/^\//,'').split('/') }; }, addArg:function(key,value){ //this if(this.urlname.indexOf('?')==-1){ this.urlname+='?'; }else{ this.urlname+="&"; }; this.urlname+=encodeURIComponent(key)+"="+encodeURIComponent(value); return this.urlname; }, addArgs:function(obj){ /*var obj ={ key:value, }*/ //this if(this.urlname.indexOf('?')==-1){ this.urlname+='?'; }else{ this.urlname+="&"; }; this.urlname+=encodeURIComponent(obj.key)+"="+encodeURIComponent(obj.value); return this.urlname; }, getQueryString:function(key){ var str = this.getSearchString().substr(1); var reg = new RegExp("(^|&)"+ key +"=([^&]*)(&|$)"); var strArray=str.match(reg);//返回一个数组 if(strArray!=null){ return unescape(strArray[2]); } return null; }, getSearchString:function(){ var mark = this.urlname.indexOf('?'); if(mark!=-1){ return decodeURIComponent(this.urlname.substr(mark)); }else{ return ''; } }, }
