9.2 upgrade to ArcGIS server9.3 related issues and some solutions (NET version) 2 client

Compared with ESRI 9.3 and 9.2, the script library in the earlier part of ESRI is also changed to a Class Library Based on ASP. net ajax, which is hard to understand and has a big header! You can only look for information to chew on. Here we recommend a practical link:

Here we also recommend a tool Aptana to help you see the methods and objects in the new class library.

The following is a question about the client:

Question 1) ------ Add a DIV to the map

This is the case. In the original version 9.2, we added our own DIV on the map to display some information.

The original method only requires the event as follows (js script)

Map. divObject. ondblclick = creatshape // map is the map object of the client.

9.3 Implementation Method

Map. _ containerDiv. ondblclick = creatshape; // map is the map object of the client.

For example, if you add your DIV to the map

Var map = $ find (wave_mapid );
Map. _ containerDiv. appendChild (this. bqshape );

 

Question 2) ------ map coordinates

The client of 9.3 encapsulates its own coordinate method, which is much more convenient. You do not need to use it on the server. Please refer to the following column

 

Function ToImgXY (Tmapx, Tmapy)
{
Var temppt = new ESRI. ADF. Geometries. Point (Tmapx, Tmapy );
Var map = $ find (wave_mapid );
Var tmpobj = map. toScreenPoint (temppt); // coordinates of the GEO coordinate to the image

Return tmpobj;
}
// Return pt
Function ToMapXY (Timgx, Timgy)
{

Var map = $ find (wave_mapid );
Var tmpobj = map. toMapPoint (Timgx, Timgy); // returns ESRI. ADF. Geometries. Point

Return tmpobj;
}

 

Of course, the above is only about one or two aspects. ESRI's customers now have a good architecture, so it is very helpful to develop it, but it is not very clear about encapsulation.
