OnCreate 事件的确认对话框

Question

当我尝试在自定义实体中创建实体记录时，我正在尝试创建一个对话框作为对用户的警告。

我写了一个JS，我试图触发表单的onSave。但是，这个对话框是在循环中弹出的。当我接受或取消活动时都会发生这种情况。

function OnFormSave(executionObj) {
    var eventArgs = executionObj.getEventArgs();
    var formContext = executionObj.getFormContext();
  //  eventArgs.preventDefault();

    if (eventArgs.getSaveMode() == 70)//AUTOSAVE
    {
        eventArgs.preventDefault();
        return;
    }

    var confirmStrings = { text: "Are you sure you want to continue to save the record?", title: "Warning" };
    var confirmOptions = { height: 250, width: 500 };
    Xrm.Navigation.openConfirmDialog(confirmStrings, confirmOptions).then(
    function (success) {
        if (success.confirmed)
        {
           // formContext.data.save();
        }
        else {
            eventArgs.preventDefault();
          
        }
    });
}

有人可以帮我解决这个问题吗？此外，此事件应该仅在创建记录时发生。有什么解决办法吗？

Answer 1

您需要检查表单类型是否处于创建模式，然后执行对话框提示代码。这会起作用。

var formType = formContext.ui.getFormType();

if(formType == 1) { //create form

    // move your code here to execute only in create form mode
}

我会把防止自动保存功能和打开对话框功能分开

function preventAutoSave(executionContext?: Xrm.SaveEventContext<any>) {
        if (executionContext == null) return;
        var eventArgs = executionContext.getEventArgs();
        if (eventArgs.getSaveMode() == 70) {
            eventArgs.preventDefault();
        }
    }

请记住，当对话框成功打开和关闭（按下取消或确定按钮）时，将调用 openConfirmDialog 的 successCallback

A function to execute when the confirmation dialog is closed by clicking the confirm, cancel, or X in the top-right corner of the dialog.

如果您希望在表单的 onSave 上使用此对话框，请考虑在表单的 onLoad 上添加：

let form = executionContext.getFormContext();
// Assuming you want to prevent auto save all times
form.data.entity.addOnSave(preventAutoSave);
form.data.entity.addOnSave(openConfirmDialog);

function openConfirmDialog() {

    var confirmStrings = { text: "Are you sure you want to continue to save the record?", title: "Warning" };
    var confirmOptions = { height: 250, width: 500 };
    Xrm.Navigation.openConfirmDialog(confirmStrings, confirmOptions).then(
    function (success) {
        if (success.confirmed)
        {
           // formContext.data.save();
        }
        else {
            eventArgs.preventDefault();
          
        }
    });
}

我试着用不同的方式回答这个问题：

var count = 0;

function OnFormSave(executionObj, para) {
    var eventArgs = executionObj.getEventArgs();
    var formContext = executionObj.getFormContext();

    if (count == 0) {
        eventArgs.preventDefault();
    }

    if (formContext.ui.getFormType() == 1 && para != null && count < 1) {


        var confirmStrings = { text: "Are you sure you want to continue to save the record?", title: "Warning" };
        var confirmOptions = { height: 250, width: 500 };
        Xrm.Navigation.openConfirmDialog(confirmStrings, confirmOptions).then(
            function (success) {
                if (success.confirmed) {
                    count = count + 1;
                    formContext.data.save();
                }
                else {
                    eventArgs.preventDefault();

                }
            });
    }
}
