防止第一个输入焦点在离子

Question

我有一个应用程序的登录屏幕，启动时，“用户名”输入自动获得焦点并弹出键盘。当键盘弹出我的登录屏幕的内容时，向上推，导致尺寸错误。

如何防止第一次输入的自动对焦？

还有一点要注意，这只发生在iOS中。在android中，它工作得很好。

这是应用程序启动时的显示方式（阻止字段并向上推送内容）

这是我的代码

<ion-view title="*************" hide-back-button="false" >

  <ion-content class="has-header" scroll="false" >




  <center style="position:relative;">

<div id="logo">
           <img src="img/lof_logo.png" style="margin-top:40px;" class="img-responsive" width="270"/>
        </div>




  <div  class="box on fadein fadeout " ng-show="toggle" ng-animate="'box'"  style="z-index:1"  >


      <div  class="container" ng-controller="LoginController">

      <form id="ftForm" name="form" autocomplete="off" novalidate shake-that  ng-submit="login(credentials)" novalidate>


          <div class="panel-body">
            <div class="form-group box-shadow" ng-class="{'has-error': form.name.$invalid && submitted}">

             <input style="padding-left:5px;"
                 type="text"
                 class="form-control"
                 id="username"
                 name="username"
                 placeholder="User Name"
                 ng-model="credentials.username"
                 ng-model-options="{updateOn: 'blur'}"
                 required>
            </div>
            <div class="form-group box-shadow" ng-class="{'has-error': form.password.$invalid && submitted}">

              <input style="padding-left:5px;"
                type="password"
                class="form-control"
                id="password"

Answer 1

您可以使用tabindex属性来指导焦点。将其设置为-1将永远不会自动对焦。

Answer 2

我唯一注意到的是

 <center style="position:relative;">

因为它是包含整个布局的div，所以它不应该设置为relative！，也许你应该将它设置为绝对。
