 *    函数名       addressLocation     
 *    描 述       在地图上显示地址匹配坐标点         
 *   参数说明      x,y：地址匹配坐标点的地图坐标
 *                 name ：地址匹配点的地图标识   
 *   返回结果      无    
 *   使用的公共变量 limitRight limitLeft limitTop limitBottom selectPointMargin
 *  
 *   aimsMap.js中的
 *   eLeft (Numeric/Dynamic) Current extent left (minimum x-coordinate).

 *   eTop (Numeric/Dynamic) Current extent top (maximum y-coordinate).
 *      Formerly called top.
 *   eBottom (Numeric/Dynamic) Current extent bottom (minimum y-coordinate).
 *      Formerly called bottom.
 *   showGeocode (Boolean/Dynamic) If true, map request will include
 *      command to draw point at geocodeX, geocodeY
 *      with an optional label. Updated by viewer on
 *      response of address match request or
 *      zoomToPoint() function.
 *   geocodeX (Numeric/Dynamic) Geocode point x-coordinate. Updated by
 *      viewer on address match response or
 *      by zoomToPoint().

接收response

processXML(theReplyIn)

Arguments:
theReplyIn--String containing returned ArcXML response.

Returned Value:
None

Description:
Passes the ArcXML response to the appropriate function for processing. The key global is XMLMode,which determines which function to call，即设定XMLMode就可以决定processXML(theReplyIn)调用哪个分析response XML的函数。

Calls: appropriate function to parse ArcXML response.

Called by: passXML in dynamic connector-created page in PostFrame on loading.

File:
aimsXML.js

 全局变量XMLMode的值<1000，由processXML(theReplyIn)调用其默认函数，>1000即用户自定义时，processXML(theReplyIn)调用useCustomFunction()函数。全局变量XMLMode在aimsXML.js中定义（见Customizing ArcIMS: HTML Viewer第308<315>页）。

useCustomFunction(theReply)

Arguments:
theReply String containing returned ArcXML response.

Returned Value:
None

Description:
Available for custom processing of returned ArcXML responses. The function processXML will call this function if the value of the global XMLMode is 1,000 or greater.

Uses: XMLMode.

Calls: hideLayer in aimsDHTML.js.

Called by: processXML in aimsXML.js.
