当在Dynamics 365中使用JavaScript单击“完成”按钮时，如何将约会标记为“完成”

Question

My code below does not work, it changes to completed and quickly changes back. .....................................................................................................................................................

function OnLoad() {

    Xrm.Page.data.process.addOnProcessStatusChange(statusOnChange);
}

function statusOnChange() {

    status = Xrm.Page.data.process.getStatus();

    if (status == "finished") {

        markAsComplete();

    }
}


function markAsComplete(){



    if (Xrm.Page.getAttribute("statecode") != null && Xrm.Page.getAttribute("statuscode") != null){

        Xrm.Page.getAttribute("statecode").setValue(1); //Changing Status to Completed
        Xrm.Page.getAttribute("statecode").setSubmitMode("always");


        Xrm.Page.getAttribute("statuscode").setValue(3); //Changing Status Reason to Completed
        Xrm.Page.getAttribute("statuscode").setSubmitMode("always");

    }else{

        alert("statecode field is not available on the form");
    }


}

To change the state of a record from JavaScript, you should either call a workflow or send a PATCH request to the Web API .

An update via the Web API would look as follows:

var appointmentId = Xrm.Page.data.entity.getId();

var entity = {};
entity.statuscode = 3;
entity.statecode = 1;

var req = new XMLHttpRequest();
req.open("PATCH", Xrm.Page.context.getClientUrl() + "/api/data/v8.2/appointments(" + appointmentId + ")", true);
req.setRequestHeader("OData-MaxVersion", "4.0");
req.setRequestHeader("OData-Version", "4.0");
req.setRequestHeader("Accept", "application/json");
req.setRequestHeader("Content-Type", "application/json; charset=utf-8");
req.onreadystatechange = function () {
    if (this.readyState === 4) {
        req.onreadystatechange = null;
        if (this.status === 204) {
            //Success - No Return Data - Do Something
        }
        else {
            Xrm.Utility.alertDialog(this.statusText);
        }
    }
};
req.send(JSON.stringify(entity));
