动态 crm 4.0 查找字段 onload() 查询

Question

I have an account entity with a lookup field schoolLookupId which refers back to a custom entity new_schools . The lookup field only display the name of the school. What I would like to be able to do using the onload() event handler of the account form is to run some javascript code that will query the new_phonenumber attribute of the new_schools entity to see if it matches a value i provide lets say var x = "1234" and if it does then update schoolLookupId accordingly with the name of the school that corresponds with the found phone number. ie update the lookup field with a phone number that already exists without creating a completely new lookup value.

I can get the attributes of the lookupfield using

var name = crmForm.all.schoolLookupid.DataValue[0].name
var id = crmForm.all.schoolLookupid.DataValue[0].id
var typename = crmForm.all.schoolLookupid.DataValue[0].typename

but I can't figure out how to retrieve, compare the data that lies behind the lookup field, and update the lookupfield accordingly.

Your help as always is invaluable.

Try put this code in load event:

   var xml = "" +  
    "<?xml version=\"1.0\" encoding=\"utf-8\"?>" +  
    "<soap:Envelope xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\">" +  
    GenerateAuthenticationHeader() +  
    " <soap:Body>" +  
    " <RetrieveMultiple xmlns=\"http://schemas.microsoft.com/crm/2007/WebServices\">" +  
    " <query xmlns:q1=\"http://schemas.microsoft.com/crm/2006/Query\" xsi:type=\"q1:QueryExpression\">" +  
    "        <q1:EntityName>new_schools</q1:EntityName>" + 
    "        <q1:ColumnSet xsi:type=\"q1:ColumnSet\">" + 
    "          <q1:Attributes>" + 
    "            <q1:Attribute>new_schoolsid</q1:Attribute>" + 
    "          </q1:Attributes>" + 
    "        </q1:ColumnSet>" + 
    "        <q1:Distinct>false</q1:Distinct>" + 
    "        <q1:Criteria>" + 
    "          <q1:FilterOperator>And</q1:FilterOperator>" + 
    "          <q1:Conditions>" + 
    "            <q1:Condition>" + 
    "              <q1:AttributeName>new_phonenumber</q1:AttributeName>" + 
    "              <q1:Operator>Equal</q1:Operator>" + 
    "              <q1:Values>" + 
    "                <q1:Value xsi:type=\"xsd:string\">"+crmForm.all.new_phonenumber.DataValue+"</q1:Value>" + 
    "              </q1:Values>" + 
    "            </q1:Condition>" +
    "          </q1:Conditions>" + 
    "        </q1:Criteria>" + 
    " </query>" +  
    " </RetrieveMultiple>" +  
    " </soap:Body>" +  
    "</soap:Envelope>" +  
    "";  

    var xmlHttpRequest = new ActiveXObject("Msxml2.XMLHTTP");
    xmlHttpRequest.Open("POST", "http://"+window.location.hostname+":"+window.location.port+"/mscrmservices/2007/crmservice.asmx", false);
    xmlHttpRequest.setRequestHeader("SOAPAction"," http://schemas.microsoft.com/crm/2007/WebServices/RetrieveMultiple");  
    xmlHttpRequest.setRequestHeader("Content-Type", "text/xml; charset=utf-8");  
    xmlHttpRequest.setRequestHeader("Content-Length", xml.length);  
    xmlHttpRequest.send(xml);  

    var resultXml = xmlHttpRequest.responseXML;

    if (_resultXml.xml.search('<q1:new_schoolsid')>0)
    {
        var val = xmlDoc.getElementsByTagName("q1:new_schoolsid")[0].childNodes[0].nodeValue;

        var lookupitem = new Array(); 
        lookupitem[0] = new LookupControlItem(val , typecode, name); 
        crmForm.all.schoolLookupid.DataValue = lookupitem ; 
    }
}

I don't try this code be careful. Use this code as a guide.
