ScaleBarbackColor, ScaleBarFont, ScaleBarStyle, ScaleBarColor, MapUnits, scalebarFontColor,
ScaleBarUnits, ScaleBarPrecision, ScaleBarSize, ScaleBarWidth, drawModeOnMap, modeBlurb,
modeMapColor, and modeMapGlow and LayerVisible, LayerID, clickPointX, and clickPointY arrays.
Calls: addSpecialRenderToMap in aimsClassRender.js (custom sample); addBufferToMap in aimsBuffer.js;
addLegendToMap in aimsLegend.js; addCustomToMap1, addCustomToMap2, addCustomToMap3,
and addCustomToMap4 in aimsCustom.js; addSelectToMap in aimsSelect.js; and getScaleBarDistance
in aimsMap.js.

Called by: clickAddPoint, resetClick, and deleteClick in aimsClick.js; getLegend in
aimsLegend.js; getPrintMap in aimsPrint.js; clearSelection in aimsSelect.js; and
sendMapXML and justGetMap in aimsXML.js.

File:
aimsXML.js

　　其中sendMapXML()函数最后调用：

sendToServer(URLString,XMLRequest,theType)

Arguments:
URLString -- String containing service URL for request.
XMLRequest -- String containing ArcXML request.
theType -- Numeric representing mode number to be passed to XMLMode. Used by processXML in passing ArcXML response to appropriate function for processing.

Returned Value:
None

Description:
Used to pass ArcXML requests on to the server(s). This function updates the form in the PostFrame page
(jsForm.htm) with the current request and processing function name.

Calls: showRetrieveMap, hideRetrieveMap, and hideRetrieveData in aimsMap.js.
Called by: functions sending ArcXML requests to the server(s).

File:
aimsXML.js

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.
