复选框保留在页刷新时检查 [英] Checkbox Stays Checked on Page Refresh

问题描述

这是一个很简单的问题（我假设）。可能是一个转贴，但我在这里找不到答案，所以这里我们走。

This a pretty simple question (I assume). Probably a repost, but I couldn't find the answer here... so here we go.

我有一个复选框，我想默认为取消选中（除非我在我的php中另有说明）。

I have a checkbox on a page that I want to default to "unchecked" (unless I specify otherwise in my php).

当我刷新页面时，如果选中该复选框，它将保持选中状态，因为选中该复选框会通过一个功能向我的页面添加一个dom元素附在箱子上。所以问题是如果我刷新，框仍然检查，但dom元素不存在（因为我没有激活的功能，我不想，除非用户选中复选框），但框是 ALREADY

When I refresh the page, if the box was checked, it will stay checked which is no-bueno because checking the box adds a dom element to my page via a function attached to the box. So the problem is if I refresh, the box is still checked, but the dom element doesn't exist (because I haven't fired the function and I don't want to unless the user checks the check box) but the box is ALREADY checked and I end up in opposite land where UN checking the box creates my dom element and checking it removes it.

基本上，问题是...

Basically, the question is...

有没有办法默认一个复选框， ？

Is there a way to default a checkbox to unchecked without javascript?

BTW除了FF 3.5.10之外的任何浏览器，我还没有检查过（没有双关语）

BTW I haven't checked (no pun intended) in any browsers other than FF 3.5.10

See http://weblogs.mozillazine.org/gerv/archives/2006/10/firefox_reload_behaviour.html (first comment):

这是这样做的目的，所以如果你点击刷新按钮你
不会失去你的工作。在Bugzilla有一个条目，
被WONTFIXed要求定期刷新，总是重置
的形式。基本上这是一个向后兼容的事情 - 每个
浏览器自NS1.0（甚至可能是Mosiac）这样做。

It’s done that way on purpose so if you tap the refresh button you don’t lose your work. There’s an entry in Bugzilla somewhere that’s been WONTFIXed asking for a regular refresh to always reset the form entirely. Basically it’s a backwards-compatibility thing — every browser since NS1.0 (maybe even Mosiac) has done that.

动态生成的网页甚至重置自己，但如果
到期设置为0，并且您按下返回按钮，它将给你一个
新表单。另外，如果表单本身改变（添加或删除元素，
改变动作等），for将在重新加载时重置。我没有
测试它，但将表单名称设置为随机的（假设你
不需要名称为js访问）可能只是工作。在PHP中像>一样。

Dynamically-generated pages don’t even reset themselves, though if the expiration is set to 0 and you hit the back button it will give you a fresh form. Also, if the form itself changes (add or remove elements, change the action, etc.) the for will reset on a reload. I haven’t tested it, but setting the form name to something random (assuming you don’t need the name for JS access) might just work. Like "> in PHP.

正如你所说，强制刷新会清除窗体，并重置它
。会像
你想要的东西（再次，没有测试）？

As you said, forcing a refresh clears the form, and resetting it does too. Would something like do what you want (again, not tested)?
