我该如何解决：HTML template must contain a single root element

Question

我正在尝试将 onsen navigator 与多个“.html”文件一起使用，但无论我尝试了什么，我都会遇到同样的错误

我的场景

-www
/脚本
index.html
home.html

我想从 index.html 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

        </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');
    }

请帮忙:v 编辑： 这是一个移动应用程序完整 html 视图： Image index.html Image home.html

Answer 1

从您的代码看来，您 </head> 没有空缺 <head>

但主要问题是您不能将 2 个标签作为根标签，这意味着您需要用一个 <html></html> 标签包裹它们

像这样：

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

Answer 2

我敢打赌您正在创建某种组件...这些组件看起来像这样：

<header>...</header>

<section>...</section>

哪个...有 2 个 'root' 个元素...对吗？

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

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

这个有1个

Onsen UI 导航器使用指定页面内容的模板，您不需要创建不同的 html 文件来指定不同的页面

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;
  }
});

   <!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>App</title>
</head>
<body>
    <ons-navigator swipeable id="myNavigator" page="page1.html"></ons-navigator>

<template id="page1.html">
  <ons-page id="page1">
    <ons-toolbar>
      <div class="center">Page 1</div>
    </ons-toolbar>

    <p>This is the first page.</p>

    <ons-button id="push-button">Push page</ons-button>
  </ons-page>
</template>

<template id="page2.html">
  <ons-page id="page2">
    <ons-toolbar>
      <div class="left"><ons-back-button>Page 1</ons-back-button></div>
      <div class="center"></div>
    </ons-toolbar>

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

解决方案很简单，几个小时后，我删除了所有 html 格式并保留了标签。

来自这里：

<!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>

对此：

<ons-page id="home">
    <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="logintest()">ENTRAR</ons-button>
        <ons-button class="loginFacebookButton">ENTRAR CON FACEBOOK</ons-button>
        <label class="labelRegister">REGISTRARME</ilabel>
    </ons-card>
</ons-page>
