[PHP] เรียกใช้ java script แล้วสั่ง return false; แต่ form มันไม่หยุดคำสั่ง action มันก็เลย add data เปล่า ๆ

เริ่มหัวข้อใหม่

Guest

java script ของผมเป็นแบบนี้ครับ
Code (JavaScript)

<script type="text/javascript">
function check(){
       if(document.myForm.name.value == ''){
            alert("คุณยังไม่ได้กรอก  ชื่อ");
            document.myForm.name.focus();
            return false;
        }      
}
</script>

ในฟอร์มก็ปกติครับ เรียกใช้ java ข้างบน

Code (PHP)

<form id="myForm" name="myForm" method="post" onsubmit="return check();" action="poolAdd_script.php">
<table> 
<tr>
      <td width="20%" class="TD_title">ชื่อ: </td>
      <td align="left" width="80%"><input type="text" name="name" value="" id="name" class="textboxlong" /></td>
    </tr>
</table>
</form>

แต่ form มันไม่หยุดคำสั่ง action มันก็เลย add data เปล่า ๆ ลงไปอ่ะครับ สาเหตุเกิดจากอะไรได้บ้างครับ

มันมี Ajax อยู่นิดหน่อยครับ ผมก็งง เพราะต้องแก้งานของคนอื่นอีกที
Code (PHP)

<?
include_once '../includes/connect.php';
?>
<script src="../includes/js/jquery/jquery.form.js" type="text/javascript"></script>
<script type="text/javascript">
       $(document).ready(function() { 
            $('#myForm').ajaxForm({ 
                dataType:  'json', 
                success:   function processJson(resPonse) { 
                            if(resPonse==1){
                                $('#Loading').hide();
                                $('#Loading1').show();
                                $('#Loading1').fadeOut(1500);
                                $('#myForm').reset();
                            } else {
                                $('#Loading1').hide();
                                $('#Loading').show();
                                $('#Loading1').show(1500);
                            }
                        } 
            }); 
        });
        
function check(){
       if(document.myForm.name.value == ''){
            alert("คุณยังไม่ได้กรอกข้อมูล ชื่อบ่อ");
            document.myForm.note.focus();
            return false;
        }      
}
</script> 
 
<form id="myForm" name="myForm" method="post" onsubmit="return check();" action="poolAdd_script.php"  enctype="multipart/form-data">
  <table width="100%" cellpadding="9" cellspacing="0" border="0">

ยาวหน่อยนะครับ

Code (PHP)

/*!
 * jQuery Form Plugin
 * version: 2.45 (09-AUG-2010)
 * @requires jQuery v1.3.2 or later
 *
 * Examples and documentation at: http://malsup.com/jquery/form/
 * Dual licensed under the MIT and GPL licenses:

;(function($) {
 
/*
    Usage Note:
    -----------
    Do not use both ajaxSubmit and ajaxForm on the same form.  These
    functions are intended to be exclusive.  Use ajaxSubmit if you want
    to bind your own submit handler to the form.  For example,
 
    $(document).ready(function() {
        $('#myForm').bind('submit', function() {
            $(this).ajaxSubmit({
                target: '#output'
            });
            return false; // <-- important!
        });
    });
 
    Use ajaxForm when you want the plugin to manage all the event binding
    for you.  For example,
 
    $(document).ready(function() {
        $('#myForm').ajaxForm({
            target: '#output'
        });
    });
 
    When using ajaxForm, the ajaxSubmit function will be invoked for you
    at the appropriate time.

 * 3. This method binds the submit() method to the form for you.

ใช้ได้ถึงแค่ บอกว่า กรอกข้อมูลไม่ครบครับ แต่มันก็ยัง insert ข้อมูลอยู่

พอเอาของ Reply บนมาใช้ ได้นะครับ เพราะมี javascript อันเดียว

แต่พอใส่ javascript เข้าไปอีกอันเพื่อโหลด page มันก็กลับไปเป็นเหมือนเดิมคือ เตือนว่าไม่ได้กรอก แต่ก็ insert อีกเหมือนกัน

โอย ทำได้แล้วครับผม :) นั่งแก้อยู่นานมาก ขอบคุณสำหรับคอมเม็นท์นะครับ
