“select”元素和跨浏览器传输数据

I've always provided a value="something" for my option elements within a select element.

我总是为select元素中的选项元素提供一个value =“something”。

Like so

<select>
   <option value="true">True</option>
</select>

Now that I have made one with countries, there is a lot of extraneous data in there. I'm pretty sure if I remember correctly, that Firefox will send the text between the tags if a value attribute is not present.

既然我已经与国家建立了一个,那里有很多无关的数据。我很确定如果我没记错,如果没有value属性,Firefox会在标签之间发送文本。

My question is, is this behaviour the norm? Can I rely on all browsers sending the innerHTML of the option element if the value attribute is omitted?

我的问题是,这种行为是常态吗?如果省略value属性,我可以依赖所有发送option元素的innerHTML的浏览器吗?

Thanks

Yes, this will work in all browsers.

是的,这适用于所有浏览器。

As the specification says:

正如规范所说:

OPTION Attribute definitions

value = cdata [CS]
This attribute specifies the initial value of the control. If this attribute is not set, the initial value is set to the contents of the OPTION element.

value = cdata [CS]此属性指定控件的初始值。如果未设置此属性,则将初始值设置为OPTION元素的内容。

Grabbed from W3C:

从W3C获取:

value = cdata [CS] This attribute specifies the initial value of the control. If this attribute is not set, the initial value is set to the contents of the OPTION element.

value = cdata [CS]此属性指定控件的初始值。如果未设置此属性,则将初始值设置为OPTION元素的内容。

With this I'd think that every major standard compliant browser should take the 'value' attribute and if it's not present take the element

有了这个,我认为每个符合标准的主要浏览器都应该采用'value'属性,如果它不存在则采用该元素
