ajax自动完成填充多个字段后的角度不读取输入更改
ajax自动完成填充多个字段后的角度不读取输入更改
提问于 2015-09-16 05:57:52
我使用jquery自动完成与ajax自动填写3个输入字段，即产品代码，描述和价格。使用角度的还有两个字段，数量和总数。
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，除非您手动更改价格，否则它无法读取价格输入。
我看过$watch，$apply，ng-change，但是一次又一次的角度无法从自动完成中看到我的范围外变量。
在柱塞中查看它，这里是http://run.plnkr.co/plunks/8g88JUPDjUfvCWupxKyT/注释:搜索“代码”输入中以01开头的产品代码。
这是我的密码

问题是，您需要访问字段的模型，而不是它自己的字段，您需要获得输入字段模型的句柄，修改它，然后应用这些更改如何实现呢？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();
}像这样的东西应该管用。可能需要一些小的变化和拼写检查。但这是一般的想法。检查这个柱塞http://plnkr.co/edit/XB7t3sePl3QbkopOoR3U?p=preview
