我使用 jquery 自动完成功能和 ajax 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:数量和总计，它们使用 Angular 。
我的问题是两个 Angular 字段不知道用户何时使用了自动完成功能。当您更改数量时，它无法读取输入的价格，除非您手动更改价格。
我查看过 $watch、$apply、ng-change，但 Angular 一次又一次无法从自动完成功能中看到我的超出范围的变量。
在此处的 Plunker 中查看它 http://run.plnkr.co/plunks/8g88JUPDjUfvCWupxKyT/ 注意:在“代码”输入中搜索以01开头的产品代码。
这是我的代码

最佳答案
问题是您需要访问字段的模型而不是字段本身，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，该怎么做？其实很简单
function jqueryAutoCompleteHandler(){
// other stuff
var angularElement=angular.element(element);
var scope = angularElement.scope();
var parser = angularElement.injector().get('$parse');
var getter = parser(angularElement.attr('ng-model'));
var setter = getter.assign;
setter(scope, value)
scope.$apply();
}
类似的东西应该可以工作。可能需要一些小的变化和拼写检查。但这就是总体思路。 检查这个笨蛋http://plnkr.co/edit/XB7t3sePl3QbkopOoR3U?p=preview
