是否显示:none禁用< input> ;? [英] Does display: none disable an <input>?
问题描述
我之前经历过以下现象:如果< input> 标记具有CSS属性 display:none ，则其值不会与父项一起提交形式.我现在很奇怪，这种行为很有帮助！
I've experienced before the phenomenon that if an <input> tag has the CSS property display: none, then its value isn't submitted with its parent form. I'm now in the curious situation where that behaviour is helpful!
我可以依靠 display:none 来防止在提交表单时包含输入内容吗?或者从技术上讲，这是对规范的偏离吗?
Can I rely on display: none to prevent inclusion of an input when its form is submitted, or is it technically a deviation from the spec?
到目前为止，答案都集中在其他方法上，以及后端验证的必要性.我知道这是一种有点奇怪的处理方式，而且我知道我需要在后端进行验证.我已经是;只是我要返回的参数格式使我处理的一个特定方面有些棘手.
The answers so far have all focussed on other ways of doing this, and the necessity of back-end validation, so let me be clear; I know this is a slightly odd way of doing things, and I know I need to validate on the back end. I already am; it's just that the format of the parameter I'm getting back makes one particular aspect of my processing slightly tricky.
尝试更清楚地重新表述问题:是否存在可靠的CSS内方式来防止输入包含在表单中?似乎是在设置字段的显示到 none 可行，但是我无法确定是否应该工作.我不在乎用户是否可能编辑前端HTML/CSS，因为我会在后端捕获它.您可能会假设一个非恶意用户.
As an attempt to rephrase the question slightly more clearly: Is there a reliable in-CSS way to prevent an input from being included with its form? It appears that setting a field's display to none works, but I haven't been able to tell whether it should work. I don't care about users potentially editing the front end HTML / CSS, because I will catch that on the back-end. You may assume a non-malicious user.
推荐答案
否.您绝对应该使用 disabled 属性.
No. You should definitely use the disabled attribute.
使用HTML5，当必填字段设置为 display:none
With HTML5, some browsers(i.e. Chrome) will even prevent you from submitting the form when a required field was set to display:none
