使用ajax进行PHP表单验证

时间：2014-09-24 09:41:01

标签： javascript php ajax forms validation

我想验证我的表格。所以我创建my_script.js并使用它的形式的onsubmit事件。 

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

但是脚本不能完全正常工作。 uname，telno1是验证，但其他如果不工作。 例如，如果username或telno1为null并单击submit1按钮，则在unametxt或telno1txt上写入javascript工作和错误。但如果密码或其他为null并单击submit1按钮，则表单已发布。 我不明白为什么两个如果声明工作，其他人不。

的index.php

如果是的话，删除其他 并且如果情况如此，它将检查所有。

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))) 
        {

那是因为只有在没有电话号码的情况下才会访问你的if（！密码）（因为你正在使用其他电话号码）。

它的作用是它将检查电话号码，如果有，它将不会执行任何其他if语句。

只需使用case语句，或者至少只使用不带else的语句。
