3. class configuration

@ Remoteproxy (name = "awdsvs_shake_perdaymodeprox ")

Public class awdsvs_shake_perdaymode

// 5:31:28 old wow's paw attilax

@ Remotemethod Public String leftnum_noreq (string uid, string actid ){

 

 

4. Test and view published methods

Http: // 192.168.1.63/Weixin/DWR/index.html

Modules known to DWR:

· Awdsvs_shake_perdaymodeprox (newcreator for com. focustar. Service. awdsvs_shake_perdaymode)

 

Click class K to see the method one tile... you can test a single method... stub has OK...

View the detailed call parameters. No JS download is allowed. No http: // 192.168.1.63/Weixin/DWR/interface/awdsvs_shake_perdaymodeprox.js download ..

 

 

5. Import to page

View Source code...

Copy ..

<SCRIPT type = 'text/JavaScript 'src = '/Weixin/DWR/engine. js'> </SCRIPT>

<SCRIPT type = 'text/JavaScript 'src = '/Weixin/DWR/interface/awdsvs_shake_perdaymodeprox.js'> </SCRIPT>

 

 

 

<SCRIPT type = 'text/JavaScript 'src = '/Weixin/DWR/util. js'> </SCRIPT>

 

 

6. Use in JS blackhead

Awdsvs_shake_perdaymodeprox.startdraw_noreq (openid, actid, function (data)

{

// Alert (data );

// Var data_json = eval (data );

VaR data_json = eval ("(" + Data + ")");

// Alert (data_json.code );

Drawaftevent (data_json );

}

);

 

7. #===== Param sh requesst

 

Do not download http: // 192.168.1.63/Weixin/DWR/interface/awdsvs_shake_perdaymodeprox.js ..

/**

* @ Param {function | object} callback function or options object

*/

P. leftnums = function (callback ){

Return DWR. Engine. _ execute (P. _ path, 'awdsvs _ shake_perdaymodeprox', 'leftnums', arguments );

};

 

 

Directly pass callback to OK lan...

The sub-database can have no rewrite scheme, and directly transmits the class K without parameters...

 

8. XXX is undefine

Thourng yeu trace L. I don't know why the trace doesn't go up... maybe it's too deep...

 

It turns out that JS can directly show pulling Lee undefine...

 

So I had to debug the FF blackhead step... but I still had to catch up with the fire. Can I debug it...

 

 

9. Warning: overloaded methods are not recommended

JavaScript does not support overloaded methods, so the Javascript file generated from this class will contain in two methods the second of which will replace the first. This is probably not what you wanted.

It is best to avoid overloaded methods when using DWR.
