让HTML5在多个聚合物飞镖组件的窗体中工作 [英] Getting HTML5 to work in Form with multiple polymer-dart components
问题描述
我正在阅读Seth Ladd的博客 http://blog.sethladd.com/2013/09/forms-http-servers-and-polymer-with-dart.html
I was reading Seth Ladd's blog at http://blog.sethladd.com/2013/09/forms-http-servers-and-polymer-with-dart.html
Lets例如我添加另一个Form组件（Form2）重复步骤3和4，然后在步骤5中导入Form2。所以步骤5应该看起来像下面的代码：
Lets say I add another Form component (Form2) repeating Steps 3 and 4, and then import Form2 in Step 5. So Step 5 should look like the code below:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Sample app</title>
<link rel="stylesheet" href="parse_form_submit.css">
<link rel="import" href="person_form.html">
<script src="packages/polymer/boot.js"></script>
</head>
<body>
<h1>Forms</h1>
<!-- Due to a bug in polymer, we can't use custom attributes.
See https://code.google.com/p/dart/issues/detail?id=12262
<person-form action="http://localhost:8888/submit"></person-form>
-->
<!-- in the meantime -->
<person-form></person-form>
<form-2><form-2>
</body>
</html>
现在我应该将提交按钮放在其中一个表单中哪些表格是进口的？在任何一种情况下，我如何获得自动验证等htnl5点击提交按钮？一切都适用于一个单一的表单，其中包含自己的提交按钮在标记内，但不是那样当提交按钮放置在标记外部。
Where should I now put the 'Submit' button - in one of the forms or in the parent into which the forms are imported? In either case, how do I get auto-validation etc by htnl5 when the submit button is clicked? Everything works fine for a single form that contains its own submit button within the tag, but not so when the submit button is placed external to the tag.
感谢
推荐答案
假设 person-form 和 form-2 是封装的表单，每个都有自己的提交按钮。
Assuming both person-form and form-2 are encapsulated forms, each will have their own submit button.
我不认为一个< form& 标签将进入Shadow DOM以查找自定义元素内的字段。所以最好的想法是：
I don't think a <form> tag will see into the Shadow DOM to find fields inside of a custom element. So best to think of it like:
my-special-form extends form
也就是说，创建一个自定义元素，它本身就是一个完全封装的形式。
That is, create a custom element that is itself a fully encapsulated form.
