//***************************************地址匹配函数******************************************
/*
* 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).
* Formerly called left.
* eRight (Numeric/Dynamic) Current extent right (maximum x-coordinate).
* Formerly called right.
* 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().
* geocodeY (Numeric/Dynamic) Geocode point y-coordinate. Updated by
* viewer on address match response or
* by zoomToPoint().
* 调 用 sendMapXML（aimsXML.js）
* 被调用

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.
