我正在使用jquery自动完成ajax来自动填写3个输入字段，即产品代码，描述和价格。还有两个字段，Quantity和total使用angular。
我的问题是两个角度字段不知道用户何时使用了自动完成。当您更改数量时，在您手动更改价格之前，它无法读取价格输入。
我看过$ watch，$ apply，ng-change，但是一次又一次，Angular无法从自动完成中看到我超出范围的变量。
在Plunker中查看http://run.plnkr.co/plunks/8g88JUPDjUfvCWupxKyT/ 注意：在＆＃34; Code＆＃34;中搜索以01开头的产品代码。输入
这是我的代码

问题是您需要访问字段的模型而不是自己的字段，您需要获取输入字段模型的句柄，修改它然后应用这些更改如何做到这一点？其实很简单
OBJECT_ID(N'TEMPDB..#t1')这样的事情应该有效。可能需要很少的变化和拼写检查。但这就是一般的想法。 检查这个plunker http://plnkr.co/edit/XB7t3sePl3QbkopOoR3U?p=preview
