在我的网页中，我在单个表单中使用两个两个提交按钮提交和保存。使用提交按钮，我想在提交表单时检查一些验证，另一个保存按钮用于提交数据，因为不需要验证数据。有没有任何javascript方法可以检查单击了哪个提交。提前感谢。

当您需要验证时，您可以使用按钮而不是提交
<input type="button" name="submit" value="Register" onclick="validateAndSubmit();" />
function validateAndSubmit()
{
//validate form here
if(valid)
{
document.getElementsByTagName("form")[0].submit();
}
else
{
//tell them what to fix
}
}
