javascript - Onclick 与提交按钮无法正常工作

Question

我想为提交按钮添加onlick。我用谷歌搜索许多教程网站都实现了所有提示，但所有这些都不能解决问题。当我将警报放入被调用的函数中时，警报正在工作但 page-join.php 中的任务不起作用。当我把onclick 与效果很好的图像。有什么问题请指导，由于表单提交，我在 firebug 中没有遇到问题安慰。所以我不明白真正的问题是什么。

//This is my function that i am calling from onclick.

  function deltpopdtl()
   {
  var ipss = '<?php echo $baseUrl ;?>/themes/gr-mist/includes/';

  $.ajax({
  url: ipss+"page-join.php?delpopdtl=<?php echo $_GET['pageid'];?>",
  success: function(data){
     }
  });}


// This is my php code(page-join.php)
     if(isset($_GET['delpopdtl'])) 
                {
       global $db;
       $getdetail = "DELETE  FROM firstloadpop WHERE rsc_id=".$_GET['delpopdtl']." and user_id= $user_id";

            mysql_query($getdetail);
             }
//This is my form and submit button
<form method="post" id="" enctype="multipart/form-data" action="#"> 

<input type="submit" id="abc" name="onladinvite" value="sendinvitation" onclick="return deltpopdtl();" />
 //i put only onlick deltpopdtl(); but the same situation, i also tired
 //onclick="return deltpopdtl();return false" but all vain

</form>

Answer 1

1. You have to write return false before function end because your form is submitted and you cant see your ajax effect.

2. You can change your submit button to type='button'

function deltpopdtl()
{
  var ipss = '<?php echo $baseUrl ;?>/themes/gr-mist/includes/';    
  $.ajax({
         url: ipss+"page-join.php?delpopdtl=<?php echo $_GET['pageid'];?>",
         success: function(data){}
  });
  return false;  //You have to add this line because your form is submitted and you cant see your ajax effec
}
