Change Record Status using javascript in CRM 2011

Sometimes we needs to change the CRM record status in java script. Following is the java script code to change the record status(deactivate,activate,qualify etc.). In this example i'm going to deactivate a custom entity record.

 
function changeRecordStatus(RECORD_ID,stateCode,statusCode) {

        // create the SetState request
        var request = "<s:Envelope xmlns:s=\"http://schemas.xmlsoap.org/soap/envelope/\">";
        request += "<s:Body>";
        request += "<Execute xmlns=\"http://schemas.microsoft.com/xrm/2011/Contracts/Services\" xmlns:i=\"http://www.w3.org/2001/XMLSchema-instance\">";
        request += "<request i:type=\"b:SetStateRequest\" xmlns:a=\"http://schemas.microsoft.com/xrm/2011/Contracts\" xmlns:b=\"http://schemas.microsoft.com/crm/2011/Contracts\">";
        request += "<a:Parameters xmlns:c=\"http://schemas.datacontract.org/2004/07/System.Collections.Generic\">";
        request += "<a:KeyValuePairOfstringanyType>";
        request += "<c:key>EntityMoniker</c:key>";
        request += "<c:value i:type=\"a:EntityReference\">";
        request += "<a:Id>" + RECORD_ID + "</a:Id>";
        request += "<a:LogicalName>cmic_systemusersalesterritoryassociation</a:LogicalName>";
        request += "<a:Name i:nil=\"true\" />";
        request += "</c:value>";
        request += "</a:KeyValuePairOfstringanyType>";
        request += "<a:KeyValuePairOfstringanyType>";
        request += "<c:key>State</c:key>";
        request += "<c:value i:type=\"a:OptionSetValue\">";
        request += "<a:Value>"+stateCode+"</a:Value>";
        request += "</c:value>";
        request += "</a:KeyValuePairOfstringanyType>";
        request += "<a:KeyValuePairOfstringanyType>";
        request += "<c:key>Status</c:key>";
        request += "<c:value i:type=\"a:OptionSetValue\">";
        request += "<a:Value>"+statusCode+"</a:Value>";
        request += "</c:value>";
        request += "</a:KeyValuePairOfstringanyType>";
        request += "</a:Parameters>";
        request += "<a:RequestId i:nil=\"true\" />";
        request += "<a:RequestName>SetState</a:RequestName>";
        request += "</request>";
        request += "</Execute>";
        request += "</s:Body>";
        request += "</s:Envelope>";

        //send set state request
        $.ajax({
            type: "POST",
            contentType: "text/xml; charset=utf-8",
            datatype: "xml",
            url: Xrm.Page.context.getServerUrl() + "/XRMServices/2011/Organization.svc/web",
            data: request,
            beforeSend: function (XMLHttpRequest) {
                XMLHttpRequest.setRequestHeader("Accept", "application/xml, text/xml, */*");
                XMLHttpRequest.setRequestHeader("SOAPAction", "http://schemas.microsoft.com/xrm/2011/Contracts/Services/IOrganizationService/Execute");
            },
            success: function (data, textStatus, XmlHttpRequest) {
                Xrm.Page.ui.close();
            },
            error: function (XMLHttpRequest, textStatus, errorThrown) {
                alert(errorThrown);
            }
        });
   

}

//Deactivating custom entity record
changeRecordStatus(Xrm.Page.data.entity.getId(),1,2);

Hope it helps!!!
