如何通过执行功能修改contentItem标签. [英] How to modify a contentItem Label from execute function.

问题描述

你好.我试图找出如何通过自定义execute方法在HTML客户端屏幕中修改contentItem的标签.

Hello. I am trying to figure out how to modify the label of a contentItem in my HTML Client screen from a custom execute method.

我只能访问屏幕对象，并且正在这里查看文档:http://msdn.microsoft.com/zh-cn/library/jj733572.aspx#requiredfield

I only have access to the screen object, and I was looking through the documentation here: http://msdn.microsoft.com/en-us/library/jj733572.aspx#requiredfield

，它具有以下代码: 

and it has this code: 

$(element).parent().find("label")[0].innerHTML += " *"

问题是，我只能从执行功能访问屏幕对象，而无法弄清楚如何访问该元素以修改html.有人知道该怎么做吗?

The problem is, that from the execute function I only have access to the screen object, and I can't figure out how to get access to the element to modify the html. Does anyone know how to do this?

这是我正在使用的功能:

Here is the function that I am working with:

myapp.AddEditJobData.ShowSetup_execute = function (screen) {
    
            $.ajax({
                url: "/ApplicationData.svc/PressSettingsSet?$filter=Id eq "+ PressSettingID,
                dataType: 'json',
                success: function (json) {
                    screen.details.rootContentItem.findItem("Temperature1")
		    //Need to set Temperature1's Label to value from json.. How to access element?

} }); }

} }); }

推荐答案

您可以使用screen.findContentItem.以下是使用dataBind进行操作的一些代码: HTH，
