角度Js模拟按Tab键按Enter键

Question

我正在尝试按角度js模拟按Tab键按下。我想在角度的筹码中实现它。我做了一些研究，但找不到合适的答案。下面是示例代码。

HTML

<chips defer ng-model="item_titles_order.item_titles_orders.$selected_imei[$index]" render="batchesView.imeiValidation(data)"  ng-keydown="batchesView.triggerEnter($event)" id = 'yourInput'>
    <chip-tmpl>
        <div class="default-chip ">
            <span>{{chip.defer}}</span>
            <i class="glyphicon glyphicon-remove" remove-chip style="margin: 0px;">
            </i>
        </div>
    </chip-tmpl>
    <input  placeholder="Type/Scan IMEI" chip-control></input>
</chips>

控制器功能

vm.triggerEnter = function(keyEvent) {
    if(keyEvent.keyCode==9){
        var e = $.Event("keydown");
        e.which = 13;
        e.keyCode = 13;
        $("#triggerEnter").trigger(e);
    }
}
