基础较差，没找出来。调试也没弄明白。
1 function GetValue(para) { 2 var reg = new RegExp("(^|&)"+ para +"=([^&]*)(&|$)"); 3 var r = this.substr(this.indexOf("\?")+1).match(reg); 4 if (r!=null) 5 return unescape(r[2]); 6 return null; 7 } 8 var str = "http://localhost:8080/ArcGIS/mapviewer.jsf?width=1059&height=523&TextString=1B024"; 9 //如果获取本页地址用var str = location.href; 10 // alert(str.GetValue("TextString")); 11 var value=str.GetValue("TextString"); 12 13 String.prototype.qt = function(query){ 14 var queryTask = new QueryTask("http://192.168.0.95:6080/ArcGIS/rest/services/SH001DangRuan1/MapServer"); 15 var query = new Query(); 16 query.where = "TextString='value'"; 17 query.returnGeometry = true; 18 query.outFields=["*"]; 19 query.execute(query,handleQueryResults); 20 } 21 22 String.prototype. handleQueryResults= function(results) { 23 var symbol = new esri.symbol.SimpeFillSymbol(esri.symbol.SimpleFillSymbol.STYLE_SOLID, new esri.symbol.SimpleLineSymbol(esri.symbol.SimpleLineSymbol.STYLE_SOLID, new dojo.Color([0,0,255,0.35]), 1),new dojo.Color([125,125,125,0.35])); 24 }; 25 adfdojo.addOnload(qt);

没报错 就是不显示效果
先 获取URL参数
然后 在地图上查询这个参数，显示效果
@谁说不可以重名: HTML代码也贴过来，我调试一下看看。

@火悬崖: js怎么调试？ 一直没弄明白
@谁说不可以重名: 
adfdojo是什么？
还有你的代码我粘贴过来怎么还有前面的序号。。。
@火悬崖: 额 我忘记了 这个是ADF框架自动生成的文件， 我只是加了JS
@谁说不可以重名: 额，ADF没有过，不知道能不能像你这样用，我调试它直接报 未定义错误，你可以用firebug(火狐)或者IE自带的开发人员工具自己调试看看。
@火悬崖: adfdojo明显是dojo库里定义的对象。
@xmodygetz: 额，不好意思，没有过这个库，你可以帮他看看怎么解决问题。
@火悬崖: 我只是听说过，没用过。但是我看了他的代码，不明白为什么他要设定String的原型，是不是可以打印一下qt的具体值看看。
虽然问题没有解决，不过还是感谢
