我正在开发由另一个程序员开发的网站。在 db 中输入数据之前，有一个表单具有 javascript 验证。但我真的不明白为什么我会收到此警报。请参见下面的代码：
function save(){
if (echeck(document.getElementById('email').value)==false){
document.getElementById('email').focus();
}else if(document.getElementById('fullname').value==''){
alert("Full name is required");
document.getElementById('fullname').focus();
}else if(document.getElementById('handphone').value==''){
alert("HP number is required");
document.getElementById('handphone').focus();
}else if(document.getElementById('bank_name').value==''){
alert("Bank Account Name is required");
document.getElementById('bank_name').focus();
}else if(document.getElementById('bank_number').value==''){
alert("Bank Account Number is required");
document.getElementById('bank_number').focus();
}else if(document.getElementById('code').value==''){
alert("Captcha Code cannot be blank");
document.getElementById('code').focus();
}else{
$.post("<?php echo base_url(); ?>index.php/misterjudi/register/", {
email:document.getElementById('email').value,
fullname:document.getElementById('fullname').value,
handphone:document.getElementById('handphone').value,
bank:document.getElementById('bank').value,
bank_name:document.getElementById('bank_name').value,
bank_number:document.getElementById('bank_number').value,
},
function(data){
alert("Successfully registered");
location.href="<?php echo base_url(); ?>";
});
}
}
因此，如果我理解正确，它会检查字段是否不为空。即使我填写了所有字段，我仍然收到类似（'全名'）的警报。
提前感谢您的帮助。
这是HTML代码：
