PHP form validation with ajax

 原文  2014-09-24 09:41:00  8   2    javascript/ php/ ajax/ forms/ validation

Question

i want to do validation my form. and so i create my_script.js and use it form's onsubmit event. 

<form id="form1" name ="form1" method="POST" action="index.php" onSubmit="return validatePassword()">

But script not work exactly. uname, telno1 is validate but other else ifs not work. For example if username or telno1 is null and click submit1 button, javascript work and error write on unametxt or telno1txt. but if password or other is null and click submit1 button, form posted. i dont understand why two if statement work, others dont.

index.php

Remove else if case and make if cases so it will check all. 

if(!username.value) {
    username.focus();
    document.getElementById("unametxt").innerHTML = "Boş bırakılamaz.";
    output = false;
  }
if(!telno1.value) {
   // telno1.focus();
    document.getElementById("telno1txt").innerHTML = "Boş bırakılamaz.";
    output = false;
  }
if((telno1.value)){
      var paswd=  /^(?=.*\d)(?=.*[0-9])(?!.*\s)/;
        if((!telno1.value.match(paswd))) 
        { 
          //  telno1.focus();
            document.getElementById("telno1txt").innerHTML = "Kod kısmında hata";
            output=false;
        }
  }
if(!password.value) {
   // password.focus();
    document.getElementById("passwordtxt").innerHTML = "Boş bırakılamaz.";
    output = false;
  }
if(!newPassword.value) {
   // newPassword.focus();
    document.getElementById("newPasswordtxt").innerHTML = "Boş bırakılamaz.";
    output = false;
  }
if(!new2Password.value) {
    new2Password.focus();
    document.getElementById("new2Passwordtxt").innerHTML = "Boş bırakılamaz.";
    output = false;
  }
if(newPassword.value!=new2Password.value) {
      newPassword.focus();
      //newPassword.value="";
      //confirmPassword.value="";
      document.getElementById("new2Passwordtxt").innerHTML = "Yeni şifreler uyuşmadı.";
      output = false;
  }  
  return output;

That's because your if(!password) is only visited if there is no phone number (because you are using else if).

So what it does is that it will check the phone number, and if there is one, it won't do any of the other if statements.

Just use a case statement, or at least use only if statements without the else.
