我正在学习，尝试创建一个简单的Web表单，验证表单数据，并将数据传递给php文件。
在验证所有字段值之后，它们不会传递给php文件。
<form action="/xxxxx.php" method="post" name="registration" onsubmit="return formValidation();">
我已将表单名称更改为其他任何内容......
<form action="/xxxxx.php" method="post" name="anythingelse" onsubmit="return formValidation();">
...表单工作（没有验证），字段值被传递给php文件。我收到完整的表格，所以我知道没有验证网页表格工作正常。
所以看起来似乎验证有问题，I.E。即使在所有函数都通过验证并且可能返回true之后，函数仍返回false。
或其他错误。我不明白什么是错的？我很感激任何帮助。
这是代码。
<script type="text/javascript">
function formValidation() {
var uname = document.registration.username;
var uadd = document.registration.city;

}
}
return false;

function validatePhone(uphone) {
var letters = /^[0-9a-zA-Z-]+$/;
if (uphone.value.match(letters)) {

答案 0 :(得分：0)
您的主if语句包含在随机的开始和结束括号内。
尝试删除这些随机大括号，在最后一个嵌套return true;语句中添加if，并在{return false;后的elseif中包含if 1}}陈述
编辑：
if (allLetter(uname)) {
if (alphanumeric(uadd)) {
if (countryselect(ucountry)) {
if (allnumeric(uzip)) {
if (ValidateEmail(uemail)) {
if (validatePhone(uphone)) {
return true;
}
else {
return false;
}
}
else {
return false;
}
}
else {
return false;
}
}
else {
return false;
}
}
else {
return false;
}
}
else {
return false;
}
有很多更好的方法可以做到这一点，但是如果不改变你已经得到的东西，请尝试以上方法。
