设置表单的隐藏输入类型 [英] Setting the a form's hidden input type
问题描述
我正在尝试更改并将
表单标记上的隐藏输入类型的值传递给基于的cgi处理脚本形式中的复选框值
：
函数CheckBoxes（）{
if（document.MyForm.CheckBox1。已检查）{
document.MyForm.recipient.value =" 2";
document.MyForm.submit（）;
} < br $>
}
...
< form name =" MyForm" action =" http://www.mycompany.com/cgi/MailMyForm.pl"
method =" post" onSubmit ="返回CheckBoxes（）">
< input type =" hidden"名称= QUOT;接受者QUOT; value =" 1">
< input name =" CheckBox1"类型= QUOT;复选框" value =" yes">
...
< / form>
显然，这是一个简化真实例子的版本。
收件人值1表示1。是一个默认收件人的电子邮件地址
情况下没有选中复选框。如果（在这种情况下）复选框
" CheckBox1"检查，然后收件人应该设置为值
" 2" cgi脚本将识别为不同的电子邮件地址
并相应地处理表单（它只会转到cgi脚本中定义的电子邮件
地址）对于接收者值2）。
任何想法为什么这不起作用？是不是我无法改变
收件人的价值？
感谢任何帮助。
Hi,
I am trying to change and pass the value of a hidden input type on a
form tag to a cgi processing script based on the value of a checkbox
within the form:
function CheckBoxes () {
if (document.MyForm.CheckBox1.checked) {
document.MyForm.recipient.value = "2";
document.MyForm.submit();
}
}
...
<form name="MyForm" action="http://www.mycompany.com/cgi/MailMyForm.pl"
method="post" onSubmit="return CheckBoxes()">
<input type="hidden" name="recipient" value="1">
<input name="CheckBox1" type="checkbox" value="yes">
...
</form>
Obviously, this is a simplified version of the real example.
The "recipient" value of "1" is a default recipient''s e-mail address in
case no checkboxes are selected. If (in this case) the checkbox
"CheckBox1" is checked, then "recipient" should get set to a value of
"2" which the cgi script will recognize as a different e-mail address
and process the form accordingly (it would just go to the e-mail
address defined in the cgi script for a "recipient" value of "2").
Any idea why this won''t work? Is it that I cannot change the value of
"recipient"?
Any help is appreciated.

为什么不摆脱这个功能，并使用onclick事件处理程序
代替它的复选框？
< form action =" http://www.mycompany.com/cgi/MailMyForm .pl"
method =" post" >
< input type =" hidden"名称= QUOT;接受者QUOT; value =" 1">
< input name =" CheckBox1"类型= QUOT;复选框" value =" yes"
onclick =''recipient.value = this.checked？" 2"：""">
但是你需要确定用户已经启用了javascript。

Why not get rid of the function, and use the onclick event handler of
the checkbox in its stead?
<form action="http://www.mycompany.com/cgi/MailMyForm.pl"
method="post" >
<input type="hidden" name="recipient" value="1">
<input name="CheckBox1" type="checkbox" value="yes"
onclick=''recipient.value=this.checked?"2":"1"''>
However you need to be certain that the user has javascript enabled.

这在大多数浏览器中都不起作用。请记住，使用ID和名称作为全局标识符是一个Microsoft标准，并不是标准化的，并且
肯定不会在所有情况下都被复制。
onclick =" this.form.elements [''recipient'']。value = this.checked？'''''''''''"
可能是最好的功能。

M.******@blueyonder.co.inva 盖子（替换.invalid ;用.uk回复）
That won''t work in most browsers. Remember that using ids and names as
global identifiers is a Microsoft-ism that isn''t standardised, and
certainly not copied in all cases.
onclick="this.form.elements[''recipient''].value=this.checked?''2'':''1''"
Probably best in a function.

是的，谢谢你的建议。我的下一个问题是，假设有
三个复选框（可以选择其中的任何一个或全部）。选中
复选框表示该表单的提交副本通过电子邮件发送给
a单独的收件人，具体取决于选中的复选框（因此，在此
简单的例子，表格会通过电子邮件发送给一个，两个或三个人）。
如何测试和处理这个？
再次感谢您的帮助？有时候我太靠近这些东西
看到简单的解决方案了！

Yes, thank for your suggestion. My next question is, suppose there are
three checkboxes (any or all of which can be selected). Checking a
checkbox indicates that a copy of the form''s submission get e-mailed to
a separate recipient depending on the checkbox checked (so, in this
simple example, the form would e-mail to one, two or three people).
How can I test and handle this?
Thanks again for your help ? sometime I get too close to these things
to see the simple solution!
