当我单击表单中的按钮时，表单已提交.如何避免这种情况?
我使用 twitter-boostrap，我想在我的表单中使用 这些单选按钮.问题是当我点击任何这些按钮时，表单会立即提交.如何避免这种情况?我只想使用默认按钮，例如单选按钮.
I use twitter-boostrap and I'd like to use these radio-buttons in my form. The problem is when I click on any of these buttons, the form is immediately submitted. How to avoid this? I just want to use default buttons like radio-buttons.

从细HTML5 规范:
未指定 type 属性的 button 元素与将 type 属性设置为 "submit" 的按钮元素表示相同的东西.
A button element with no type attribute specified represents the same thing as a button element with its type attribute set to "submit".
还有一个 <button type="submit"> 提交表单，而不是像一个简单的 <button type="button"> push-button.
And a <button type="submit"> submits the form rather than behaving like a simple <button type="button"> push-button.
HTML4 规范 说了同样的话:
type = submit|button|reset [CI]
此属性声明按钮的类型.可能的值:
type = submit|button|reset [CI]
This attribute declares the type of the button. Possible values:
submit:创建提交按钮.这是默认值.reset:创建一个重置按钮.button:创建一个按钮.
submit: Creates a submit button. This is the default value.reset: Creates a reset button.button: Creates a push button.
所以你的 <button> 元素:
<button class="btn">Button_1</button>
<button class="btn">Button_2</button>
与这些相同(在兼容的浏览器中):
are the same as these (in compliant browsers):
<button type="submit" class="btn">Button_1</button>
<button type="submit" class="btn">Button_2</button>
只要您点击其中一个按钮，您就会提交表单.
and any time you hit one of those buttons you'll submit your form.
解决方案是使用普通按钮:
The solution is to use plain buttons:
<button type="button" class="btn">Button_1</button>
<button type="button" class="btn">Button_2</button>
某些版本的 IE 默认为 type="button"，尽管标准有什么规定.在使用 <button> 时，您应该始终指定 type 属性，以确保您获得预期的行为.
Some versions of IE default to type="button" despite what the standard says. You should always specify the type attribute when using a <button> just to be sure that you will get the behavior you're expecting.
