最近在newsgroup经常有人问怎么在javascript使用Microsoft Dynamics CRM Web Services 获取mscrm数据,在mscrmsdk4.0中已经有Accessing Web Services in JScript相关介绍了,看了sdk后你是否还是觉得要写js访问webservice来解决自己的实际问题还是很困难? 下面我来介绍 [stunnware][]写的一个程序[Calling CRM Services from JavaScript][],通过这个程序你可以很容易来构建你的js代码实现具体的需求.  
  
在vs.net中打开项目，在Form1设计界面点击start按钮,在click事件中,写访问webservice的代码,下面我提供一个比较简单的通过产品guid获取productnumber和price.

///   <summary>   
       ///  Starts the execution of a web service. Put your code inside the try block. You can use   
       ///  every web service you like, so you're not limited to query expressions.   
       ///   </summary>   
       ///   <param name="sender"></param>   
       ///   <param name="e"></param>   
        private   void  buttonStart\_Click( object  sender, EventArgs e) \{  
  
         buttonStart.Enabled  =   false ;  
         textBoxRequest.Text  =   string .Empty;  
         textBoxResponse.Text  =   string .Empty;  
          try    
         \{  
             ColumnSet cols  =   new  ColumnSet();  
             cols.Attributes  =   new   string \[\] \{  " productnumber " , " price " \};  
             Guid productGuid  =   new  Guid( " 066BC88D-01C4-DC11-A4B2-001D09006D68 " );  
             CrmLogService service  =   new  CrmLogService();  
             service.Url  =   " http://localhost/mscrmservices/2006/crmservice.asmx " ;  
             service.Credentials  =  System.Net.CredentialCache.DefaultCredentials();  
             service.SoapMessageSerializationFinished  \+=   new  SoapMessageEventHandler(service\_SoapMessageSerializationFinished);  
             service.Retrieve(EntityName.product.ToString(), productGuid, cols);  
         \}  
          catch  (Exception x)   
         \{  
            ExceptionBox.Show( this , x);  
         \}  
          finally  \{  
            buttonStart.Enabled  =   true ;  
         \}  
      \}

运行程序,点start按钮,可以得到下面结果:

把JavaScript Code 中的代码copy到onload事件中,在加入下面代码来获取具体属性的值  
var doc = xmlHttpRequest.responseXML;  
var user = doc.selectSingleNode("//BusinessEntity");

var productnumber = user.selectSingleNode("productnumber").text;  
//var productnumber = user.selectSingleNode("q1:productnumber").text; // mscrm4.0  
alert(productnumber);

var price = user.selectSingleNode("price").text;  
//var price = user.selectSingleNode("q1:price").text; //mscrm4.0  
alert(price);
