CrmService.Create Method Using JScript

This sample shows how to use the CrmService.Create method using the same example provided in the Server Programming Guide

// Prepare values for the new contact.
var firstname = "Jesper";
var lastname = "Aaberg";
var donotbulkemail = "true";
var address1_stateorprovince = "MT";
var address1_postalcode = "99999";
var address1_line1 = "23 Market St.";
var address1_city = "Sammamish";
var authenticationHeader = GenerateAuthenticationHeader();

// Prepare the SOAP message.
var xml = "" + 
"" xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'"+
" xmlns:xsd='http://www.w3.org/2001/XMLSchema'>"+ 
authenticationHeader+
""+ 
""+ 
""+ 
""+address1_city+""+ 
""+address1_line1+""+ 
""+address1_postalcode+""+ 
""+address1_stateorprovince+""+ 
""+donotbulkemail+""+ 
""+firstname+""+ 
""+lastname+""+ 
""+ 
""+ 
""+ 
"";
// Prepare the xmlHttpObject and send the request.
var xHReq = new ActiveXObject("Msxml2.XMLHTTP");
xHReq.Open("POST", "/mscrmservices/2007/CrmService.asmx", false);
xHReq.setRequestHeader("SOAPAction","http://schemas.microsoft.com/crm/2007/WebServices/Create");
xHReq.setRequestHeader("Content-Type", "text/xml; charset=utf-8");
xHReq.setRequestHeader("Content-Length", xml.length);
xHReq.send(xml);
// Capture the result
var resultXml = xHReq.responseXML;

// Check for errors.
var errorCount = resultXml.selectNodes('//error').length;
if (errorCount != 0)
{
 var msg = resultXml.selectSingleNode('//description').nodeTypedValue;
 alert(msg);
}
// Open new contact record if no errors.
else
{
   var contactid = resultXml.selectSingleNode("//CreateResult");
 window.open("/sfa/conts/edit.aspx?id={"+contactid.nodeTypedValue+"}");
}

A successful response includes XML with a CreateResponse element that returns the ID for the record created. The following is an example of a successful response:

 
  
   368c8b1b-851c-dd11-ad3a-0003ff9ee217
  
 

Changing the title of a CRM form

This will cahange the title of the crm From

document.title = "Hello World!";

JavaScript StringBuilder

a simple StringBuilder class that pushes individual strings into an array and then uses the join method to produce the concatenated output string.

	/ Initializes a new instance of the StringBuilder class
	// and appends the given value if supplied
	function StringBuilder(value)
	{
	this.strings = new Array("");
	this.append(value);
	}
	// Appends the given value to the end of this instance.
	StringBuilder.prototype.append = function (value)
	{
	if (value)
	{
	this.strings.push(value);
	}
	}
	// Clears the string buffer
	StringBuilder.prototype.clear = function ()
	{
	this.strings.length = 1;
	}
	// Converts this instance to a String.
	StringBuilder.prototype.toString = function ()
	{
	return this.strings.join("");
	}

The code is simple and straightforward that it should be self-explanatory. Now here's an example of how to use it:

// create a StringBuilder
var sb = new StringBuilder();

// append some text
sb.append("Lorem ipsum dolor sit amet, consectetuer adipiscing elit, ");
sb.append("sed diem nonummy nibh euismod tincidunt ut lacreet dolore ");
sb.append("magna aliguam erat volutpat.");

// get the full string value
var s = sb.toString();

Adding additional values to duration fields

The following script adds the new option "42 Minutes" to the actualdurationminutes field in a task:

var duration = crmForm.all.actualdurationminutesSelect;

var tables = duration.getElementsByTagName("table");
var table = tables[1];

var row = table.insertRow();
var newOption = row.insertCell(-1);

var newValue = "42 Minutes";
newOption.setAttribute("val", newValue);
newOption.innerText = newValue;

Replacing the content of an IFRAME

If you really want to do some funny things in your CRM form, you can create an IFRAME serving as a placeholder for your real HTML code. Create an IFRAME in an entity and name it "IFRAME_TEST". In the Onload event put the following code:

crmForm.all.IFRAME_TEST_d.innerHTML ="Some HTML text";

Note the "_d" at the end of IFRAME_TEST. This single line replaces the whole IFRAME element with your own HTML.
