javascript - 如何从表单标签之外的按钮手动触发 AngularJS 验证？

Question

给定这段代码:

<div ng-controller="MyCtrl">
    <form ng-submit="onSubmitted()">

    Header inputs:
        <input type="name" ng-model="sample" required/>
        <input type="name" ng-model="sampleX" required/>

        <input type="submit" value="This submit triggers validation. But I wanted to put this button at the end of the page"/>
    </form>

    <hr/>

    Some other form here. Think line items

    <hr />
    <a class="btn" ng-click="/* what could should be put here, so this can trigger the firt form's validation, then submit? */">Wanted this submit button to trigger the validation+submit on the form in which this button doesn't belong</a>


</div>


var app = angular.module('myApp', []);

function MyCtrl($scope) {

    $scope.onSubmitted = function() {
        alert('submitted!');
    };
}

我希望最后一个按钮在第一个表单上触发验证(然后在有效时提交)。截至目前，只有表单内的按钮可以触发该表单的验证和提交。表单外的按钮是否有任何可能的方法来做到这一点？

您可以创建指令，然后附加到 <a class="btn"... .检查这个 jsfiddle

请注意，我添加到 <input type='submit' id='clickMe'...并将其链接到底部的链接 <a class='btn' linked="clickMe"...
