Javascript 点击回车后获取值

我想在按下回车键后获得输入值

我的xhtml看起来像

                        <div class="medium-12 columns">
                            <input name="verificationCode" ng-enter="enteredVerificationCode()" ng-model="user.verificationCode" type="text" id="verificationCode" placeholder="Enter Verification Code Here"  />
                            <div ng-messages="formSubmitted &amp;&amp; signupForm.email.$error">
                                <div ng-message="required" class="error">Verification Code is required.</div>
                            </div>
                        </div>

---

}

您可以将其包装在表单标记中

<form ng-submit="enteredVerificationCode()">
    <div class="medium-12 columns">
        <input name="verificationCode" ng-model="user.verificationCode" type="text" id="verificationCode" placeholder="Enter Verification Code Here"  />
        <div ng-messages="formSubmitted &amp;&amp; signupForm.email.$error">
            <div ng-message="required" class="error">Verification Code is required.</div>
        </div>
    </div>
</form>

需要验证码。

您可以使用来检测按键笔划，并查找enter键（13）以触发

enteredVerificationCode（）

函数

<input ng-keypress=keypressed($event) ng-model="verificationCode">    

$scope.keypressed = function(event) {

   if (event.keyCode === 13)
       enteredVerificationCode()

}

$scope.keypressed=函数（事件）{
如果（event.keyCode===13）
输入验证代码（）
}

<input ng-keypress=keypressed($event) ng-model="verificationCode">    

$scope.keypressed = function(event) {

   if (event.keyCode === 13)
       enteredVerificationCode()

}
