我该如何解决:HTML模板必须包含一个根元素

问题描述 投票:-1回答:3

我正在尝试将温泉导航器与多个“ .html”文件一起使用,但是无论遇到什么尝试,我都会遇到相同的错误

我的场景

  • -www
  • /脚本
  • index.html
  • home.html

我想从index.html转到home.html

错误:

Uncaught (in promise) Error: [Onsen UI] HTML template must contain a single root element
    at Object.Q.throw (onsenui.min.js:2)
    at Object.Q.createElement (onsenui.min.js:2)
    at onsenui.min.js:2

我的index.html:

    <link rel="stylesheet" href="https://unpkg.com/onsenui/css/onsenui.css">
    <link rel="stylesheet" href="https://unpkg.com/onsenui/css/onsen-css-components.min.css">
    <script src="https://unpkg.com/onsenui/js/onsenui.min.js"></script>

    <script src='scripts/loginScript.js' type='text/javascript'></script>

    <link rel="stylesheet" href="style.css">
    <title>Tu Psicologa de Cabecera</title>
</head>
<body>
    <ons-navigator id="navigator" page="index.html"></ons-navigator>
        <ons-template id="index.html">
            <ons-page id="index">
                <img class="imagenLogo" src="https://i.imgur.com/cq7BbWn.png">

                <ons-card class="loginCard">
                    <ons-input id="userLogin" modifier="underbar" placeholder="Usuario" style="width: 100%; margin-top: 8px; margin-bottom: 8px;" float></ons-input>
                    <ons-input id="passLogin" modifier="underbar" placeholder="Contraseña" type="password" style="width: 100%; margin-top: 8px; margin-bottom: 8px;" float></ons-input>

                    <ons-button class="loginButton" onclick="loginNomral()">ENTRAR</ons-button>
                    <ons-button class="loginFacebookButton">ENTRAR CON FACEBOOK</ons-button>
                    <label class="labelRegister">REGISTRARME</ilabel>
                </ons-card>
            </ons-page>
        </ons-template>
    <script type="text/javascript" src="cordova.js"></script>
</body>

我的home.html

   <!DOCTYPE html>
   <html>
   <head>
    <meta charset="utf-8">
    <meta name="viewport" content="initial-scale=1, maximum-scale=1, user-scalable=no, width=device-width">

    <link rel="stylesheet" href="https://unpkg.com/onsenui/css/onsenui.css">
    <link rel="stylesheet" href="https://unpkg.com/onsenui/css/onsen-css-components.min.css">
    <script src="https://unpkg.com/onsenui/js/onsenui.min.js"></script>

    <link rel="stylesheet" href="style.css">
    <title></title>
</head>
<body>
    <ons-page id="home">
        <ons-toolbar>
            <div class="left"><ons-back-button>Page 1</ons-back-button></div>
        </ons-toolbar>

        <p>This is the second page.</p>
    </ons-page>
</body>
</html>

还有我的剧本:

    function loginNomral(){
        const navigator = document.querySelector('#navigator');
        navigator.resetToPage('home.html');

        ons.notification.alert('test');
    }

请帮助:v编辑:这是针对移动应用的完整的html视图:Image index.htmlImage home.html

Onsen UI导航器可与您在其中指定页面内容的模板一起使用,无需创建其他html文件来指定其他页面

document.addEventListener('init', function(event) {
  var page = event.target;

  if (page.id === 'page1') {
    page.querySelector('#push-button').onclick = function() {
      document.querySelector('#myNavigator').pushPage('page2.html', {data: {title: 'Page 2'}});
    };
  } else if (page.id === 'page2') {
    page.querySelector('ons-toolbar .center').innerHTML = page.data.title;
  }
});

   <html>

      <div class="center">Page 1</div>
    </ons-toolbar>

因为它与您的代码相同,所以您有</head>而没有打开<head>

但是主要问题是您不能将2个标签作为根,这意味着您将需要使用单个<html></html>标签将它们包装起来

像这样:

<html>
   <head>
      <title>Page Title</title>
   </head>
   <body>
      <h1>My First Heading</h1>
      <p>My first paragraph.</p>
   </body>
</html>

我敢打赌,您正在创建某种类型的组件...而这些组件看起来像这样:

<header>...</header>

<section>...</section>

哪个...具有2个'root'元素...对吗?

<aside class='component-name'>
  <header>...</header>

  <section>...</section>
</aside>

有1。
