谢谢但它似乎不起作用。
这在这里有效：
< input type =" text"名称= QUOT;电子邮件" value =" e-mail"
onClick =" if（this.value ==''e-mail''）this.value =''''">
然后就在下面，根据你的
建议我有我的提交按钮的行：
< input type = [提交" value =" Go！"
onClick =" if（this.form.elements [''e-mail'']。value ==''e-mail''）this。 form.elements [''e-mail'']。value =''''">
不幸的是它不起作用。
还有其他想法吗？
谢谢！

很抱歉这个混乱，当你第一次发布时我曾想过你的输入元素的名字是
"电子邮件" ;.这次尝试使用相同的解决方案
用''email''替换''e-mail''：
this.form.elements [''email ''] .value
In an unnamed form, unnamed because it only submits an email address, I''m
trying to have the submit button clear the "e-mail" text value in the
textbox.
On the submit button I have the following:
onClick="if(this.form[''e-mail''].value==''e-mail'')this.form[''e-mail''].value=''''"
But it does not seem to work. Any ideas or suggestions?
Thanks in advance!

You are accessing the form elements incorrectly. Try the following
instead:
this.form.elements[''e-mail''].value

This here works:
<input type="text" name="email" value="e-mail"
onClick="if(this.value==''e-mail'')this.value=''''">
Then right below I have the line for my submit button as per your
suggestion:
<input type="submit" value="Go!"
onClick="if(this.form.elements[''e-mail''].value==''e-mail'')this.form.elements[''e-mail''].value=''''">
Unfortunately it''s not working.
Any other ideas?
Thanks!

Sorry for the confusion, when you first posted I had thought the name
of your input element was "e-mail". Try the same solution this time
replacing ''e-mail'' with ''email'':
this.form.elements[''email''].value
