javascript - 使用 Javascript 清空 CRM 2013 中电子邮件实体中的发件人字段

Question

因此，每当我加载页面时，我都会尝试清空电子邮件实体上的发件人字段。我正在尝试使用 javascript 来做到这一点。我的代码如下。

function emptyField(fieldName) {
    var personType = Xrm.Page.getAttribute(fieldName).DataValue = [];
}

我也尝试过

function emptyField(fieldName) {
    var personType = Xrm.Page.getAttribute(fieldName).DataValue = null;
}

但是这些方法似乎都不起作用。谁能告诉我我能做什么？

Answer 1

OOB functionality像这样:

function emptyField(fieldName) {
    Xrm.Page.getAttribute(fieldName).setValue(null);
}

仔细检查 MSDN 页面中的注释:

Updating an attribute using setValue will not cause the OnChange event handlers to run. If you want the OnChange event handlers to run you must use fireOnChange in addition to setValue.

When Microsoft Dynamics CRM for tablets is not connected to the server setValue will not work.

You cannot set the value of composite attributes. More information: Write scripts for composite attributes.
