我创建了一个用户可以注册的注册页面,我正在尝试检查:电子邮件是否有效,电子邮件是否匹配,密码是否符合长度要求,以及密码是否匹配。但它不能正常工作。 html代码采用相同的形式
电子邮件表格行:
<tr>
<td></br>Email Address:</td>
</tr>
<tr>
<td><input id="em100" type="email" name="email1" required>
</td>
</tr>
<tr>
<td></br>Confirm Email Address:</td>
</tr>
<tr>
<td><input id="em101" type="email" name="email2" required></td>
</tr>
密码表行:
<tr>
<td></br>Password:</td>
</tr>
<tr>
<td><input id="pw100" type="password" name="pass1" required></td>
</tr>
<tr>
<td></br>Confirm Password:</td>
</tr>
<tr>
<td><input id="pw101" type="password" name="pass2" required></td>
</tr>
提交表格行:
<tr>
<td style="padding-top: 10px;"></br><input type="submit" value="Register" onclick="regValidation();"></td>
</tr>
Javascript代码:
function regValidation()
{
document.getElementById('td100').innerHTML = "";
event.preventDefault ? event.preventDefault() : event.returnValue = false;
var email1 = document.getElementById('em100').value;
var email2 = document.getElementById('em101').value;
var pass1 = document.getElementById('pw100').value;
var pass2 = document.getElementById('pw101').value;
if (document.getElementById('em100').checkValidity()) {
if (email1 = email2) {
if (pass1 = pass2) {
if (pass1.length >= @minPass || pass1.length <= @maxPass) {
return true && regSuccess();
} else {
document.getElementById('td100').innerHTML += "</br>Password must be @minPass - @maxPass characters.";
}
} else {
document.getElementById('td100').innerHTML += "</br>Passwords do not match.";
}
} else {
document.getElementById('td100').innerHTML += "</br>Emails do not match.";
}
} else {
document.getElementById('td100').innerHTML += "</br>Emails are not valid.";
}
}
function regSuccess()
{
alert("Thank you for signing up!");
document.getElementById('fm101').submit();
return;
}

你需要进行比较,并且可以更容易地将ifs链接起来:
function getError(){
if(pass1 !== pass2) return "password missmatch";
if(email1 !== email2) return "emails missmatch";
if(pass1.length < min || pass1.length > max) return "password to long/short";
return false;
}
所以你可以做到
var error = getError();
if(!error){
return alert(" all fine");
}
alert(error);
答案 1 :(得分:0)
在条件中,您要分配值:
CELERY_ENABLE_REMOTE_CONTROL = False
CELERY_SEND_EVENTS = False
这应该是
if (pass1 = pass2)
答案 2 :(得分:-1)
1检查 if 语句 如果(EMAIL1 == EMAIL2) {}
pass1和pass2的相同内容 如果(PASS1 == PASS2) {}
2如果你把
<input type="email">
浏览器会自动为您执行电子邮件验证
3检查密码是否超过最大长度只需添加即可 输入标记的 maxlength 属性
<input type="password" maxlength="10">
这样可以省去编写额外的js代码
