在服务器端更新字段后防止触发OnChange函数

本文介绍了在服务器端更新字段后防止触发OnChange函数的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

当我向字段注册一个OnChange函数时,如果该字段在服务器端的插件上更新(在Dynamics Crm 2015上),它将被触发

When I register an OnChange function to a field, it gets fired if the field is updated on a plugin on the server side (On Dynamics Crm 2015)

可以

示例代码:

1。客户端:

Xrm.Page.getAttribute("org_myfield").addOnChange(function () { alert("org_myfield was changed") });

2。服务器端:

internal void OnPreUpdateRequest(org_myentity target, org_myentity preImage)
{
    target.org_myfield = "some value";
}

3。结果(保存记录并且插件完成运行之后):

3. Result (after saving the record and plugin finished its run):

"org_myfield was changed"

所需结果:不应触发警报。

推荐答案

我相信这就是您要获得的:


1.用户在此字段上进行更改时,调用JavaScript on change函数;


2.保存记录时,插件也可能会更改字段的值;


3.如果插件更改了字段值,请跳过JavaScript函数。

I believe this is what you are trying to get:
1. When user makes change on this field, call the JavaScript on change function;
2. When the record is saved, a plugin might change the value of the field as well;
3. If the field value is altered by the plugin, skip the JavaScript function.

如果这是正确的,我可以这样尝试:


从字段中删除 onChange 事件,而在中检查字段状态表单的onSave 事件。


使用 Xrm.Page.getAttribute( org_myfield)。getIsDirty()确定用户是否对领域。它只会在客户端检查更改,因此不会受到插件的影响。

If this is correct, I would try this way:
Remove the onChange event from the field, instead check the field status in onSave event of the form.
Use Xrm.Page.getAttribute("org_myfield").getIsDirty() to determine whether the user makes any change on the field. It only checks the changes on client side so it won't be affected by plugin.
