Lightswitch html客户端覆盖默认保存按钮 [英] Lightswitch html client override default save button

问题描述

我希望能够覆盖html客户端上的默认保存按钮，但我似乎无法找到控制。我想在它后面写一些验证，并允许用户选择一个选项，但我似乎无法找到它。

I want to be able to override the default save button on the html client however i cant seem to find the control to do so. I want to write some validation behind it and allow the user to select an option but I just cant seem to find it.

我知道Silverlight客户端可以覆盖它，但只是似乎无法在HTML客户端覆盖它。

I know the silverlight client you can override it but just cant seem to override it in the html client.

感谢

thanks

推荐答案

这是使用beforeApplyChanges实现的。

It's achieved using beforeApplyChanges.

例子:(请原谅任何输入错误/语法错误，你会得到大概的想法！）

example: (Please excuse any typos/syntax errors, you get the rough idea!)

myapp.AddEditScreen.beforeApplyChanges = function (screen) {
    switch (screen.Property_SavingStatus) {
    case 'Not Saving':
        setTimeout(function () {
            // Override Save -> toggle SavingStatus -> Call Save again
            SaveMyChangesMyWay();
            screen.Property_SavingStatus = 'Commit';
            myapp.commitChanges(); // Or Discard or Apply.
        }, 500);
        return false; // Cancel save changes request
        break;
    case 'Apply':
        return true;
        break;
    default:
};
