Posted on by Community Member Microsoft Employee

Hi everyone,

The following script is trigger on field change.

if I comment the line  alert(""+projectTitleValue); then my variable projectTitleValue has the value before change and not after change. My script has no failure but don´t have the expected behavior. Do you have any idea why?

I´m a newbie with CRM customization and JavaScript. Thanks.

function onChange_Duplicate() {
	Xrm.Page.data.entity.save();
	var projectTitle = Xrm.Page.getAttribute("eno_projecttitle_kd");
	var projectTitleValue = projectTitle.getValue();
	var serverUrl = Xrm.Page.context.getClientUrl();
	var ODataPath = serverUrl + "/XRMServices/2011/OrganizationData.svc";
	var retrieveResultProjectTitle = new XMLHttpRequest();
	alert(""+projectTitleValue);
	if (projectTitleValue != null) {

		retrieveResultProjectTitle.open("GET", ODataPath +"/OpportunitySet?$select=eno_projecttitle_kd&$filter=eno_projecttitle_kd eq '"+projectTitleValue+"'",false);
		retrieveResultProjectTitle.setRequestHeader("Accept", "application/json");
		retrieveResultProjectTitle.setRequestHeader("Content-Type", "application/json; charset=utf-8?");
		retrieveResultProjectTitle.send('grant_type=client_credentials');
		if (retrieveResultProjectTitle.readyState == 4) {
			if (retrieveResultProjectTitle.status == 200) 
			{
				var retrieved = this.parent.JSON.parse(retrieveResultProjectTitle.responseText).d;
				var Result = retrieved.results;
				if (typeof Result !== "undefined")
				{
					var count = Result.length;
					if (count>1)
					{
						alert("There is already an entity with this Project Title");
					} 
				}
			}

		}
	}
}

    Hi Goutam,

    thanks for your answer. I test it and I meet an error: JSON is undefined or null at this line: var retrieved = this.parent.JSON.parse(retrieveResultProjectTitle.responseText).d;

    Do you have an idea?

    Thanks a lot!

    Hi Leo,

    Try with this -

    //Need to register only below method field Onchange.

    function onChange_Duplicate() {   
    Xrm.Page.data.save().then(succesCallback, errorCallback);
	
}

function succesCallback()
{
    var projectTitle = Xrm.Page.getAttribute("eno_projecttitle_kd");
    var projectTitleValue = projectTitle.getValue();
    var serverUrl = Xrm.Page.context.getClientUrl();
    var ODataPath = serverUrl + "/XRMServices/2011/OrganizationData.svc";
    var retrieveResultProjectTitle = new XMLHttpRequest(); 
    if (projectTitleValue != null) {

        retrieveResultProjectTitle.open("GET", ODataPath + "/OpportunitySet?$select=eno_projecttitle_kd&$filter=eno_projecttitle_kd eq '" + projectTitleValue + "'", false);
        retrieveResultProjectTitle.setRequestHeader("Accept", "application/json");
        retrieveResultProjectTitle.setRequestHeader("Content-Type", "application/json; charset=utf-8?");
        retrieveResultProjectTitle.send('grant_type=client_credentials');
        if (retrieveResultProjectTitle.readyState == 4) {
            if (retrieveResultProjectTitle.status == 200) {
                var retrieved = this.parent.JSON.parse(retrieveResultProjectTitle.responseText).d;
                var Result = retrieved.results;
                if (typeof Result !== "undefined") {
                    var count = Result.length;
                    if (count > 1) {
                        alert("There is already an entity with this Project Title");
                    }
                }
            }

        }
    }

}

function errorCallback()
{
    alert("error");
}
