js location.search 用法详解

JS中location.search什么意思？下面17javascript跟大家详细介绍一下： 设置或获取 网页地址跟在问号后面的部分 当以get方式在url中传递了请求参数时，可以利用location的search属性提取参数的值，下面的代码把参数的名称和对应的值存储在2个数组中。 <script> function test() { var url=window.location.search; if(url.indexOf("?")!=-1) { var str = url.substr(1) strs = str.split("&"); var key=new Array(strs.length); var value=new Array(strs.length); for(i=0;i<strs.length;i++) { key[i]=strs[i].split("=")[0] value[i]=unescape(strs[i].split("=")[1]); alert(key[i]+"="+value[i]); } } } < /script> -------------------------------------------------------------- < html> < head><title>none</title> < script> function getParam(name){ var params=location.search.substring(1).toLowerCase();alert(params=+params); var paramList=[]; var param=null; var parami; if(params.length>0) { if(params.indexOf("&") >=0) { paramList=params.split( "&" ); }else { paramList[0] = params; } for(var i=0,listLength = paramList.length;i<listLength;i++) { parami = paramList[i].indexOf(name+"=" ); if(parami>=0) { param =paramList[i].substr(parami+(name+"=").length); } } } return param; } function check(){ id=document.getElementById(test).value;alert(one+id); var userid=getParam(id);alert(two+userid); var flag=false; var str=2010001,2010002,2010003,2010004,2010005,2010006,2010007,2010008,2010009,2010010,2010011,2010012,2010013,2010014,2010015,2010016,2010017,2010018,2010019,2010020,2010021,2010022,2010023,2010024,2010025,2010026,2010027,2010028,2010029,2010030,2010031,2010032,2010033,2010034,2010035,2010036,2010037,2010038,2010039,2010040,2010041,2010042,2010043,2010044,2010045,2010046,2010047,2010048,2010049,2010050,2010051,2010052,2010053,2010054,2010055,2010056,2010057,2010058,2010059,2010060,2010061,2010062,2010063,2010064,2010065,2010066,2010067,2010068,2010069,2010070,2010071,2010072,2010073,2010074,2010075,2010076,2010077,2010078,2010079,2010080,2010081,2010082,2010083,2010084,2010085,2010086,2010087,2010088,2010089,2010090,2010091,2010092,2010093,2010094,2010095,2010096,2010097,2010098,2010099; var arr=str.split(,); for(var i=0,l=arr.length;i<l;i++){ if(userid == arr[i]) { flag=true; break; } } if(!flag){ alert(demine!); return false; }else{ alert(right); } } < /script> < /head> < body> < table > < form> 请输入<input type="text" name="test" id="test"/> < input type="button" value="确认"/> < /form> < /table> < /body> < /html>
