通过javascript使用Microsoft Dynamics CRM Web Services

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);
