如何通过Javascript更新Microsoft CRM Online上的表单域 [英] How can I update form field on Microsoft CRM Online via Javascript

问题描述

我刚刚在Microsoft Dynamics CRM Online上创建了自定义订单表单。

I've just created a custom order form on the Microsoft Dynamics CRM Online.

基本上，我想将总金额字段更新为数量和金额字段的乘积。我想我可以通过Javascripts来做到这一点。我刚打开数量字段属性菜单并进入事件菜单。它需要选择一个js库并编写正确的函数。我很确定这太容易了，但是，我不知道怎么办。

It requires to select a js library and write right function. I'm quite sure it's too much easy, however, I do not know how to do.

基本上：

更新金额字段X数量字段应为=总金额字段值。我的脚本应该在更改事件的数量字段上运行。

Update Amount Field X Quantity Field should be = Total Amount Field value. My script should run on Quantity Field on Change event.
