我想使用ajax将数据插入表中,因此数据将插入而无需重新加载页面。

该代码很好地将数据插入到表中,但是代码也重新加载了页面。

但是我想插入而不重新加载页面。

我怎样才能做到这一点 ?

<?php
include('connection.php');
if(isset($_POST['cmt'])){
    $comment = addslashes($_POST['cmt']);
    $alertid = $_POST['alert_id'];
    mysql_query("INSERT INTO `comments` (`id`, `alert_id`, `comment`, `username`) VALUES (NULL, '".$alertid."', '".$comment."', 'tomas')");
}
?>


<script>
  function submitform(){
    var comment = $("#comment").val();
    var alertid = $("#alertid").val();
    $.ajax({
        type: "POST",
        //url: "ana.php",
        data:{cmt:comment,alert_id:alertid}
    }).done(function( result ) {
        $("#msg").html( result );
    });

  }
</script>

<form method = "POST" onsubmit = "submitform()">
   <textarea onFocus = "myFunction(1)" onBlur = "myFunction(0)" style="margin: 0px 0px 8.99305534362793px; width: 570px; height: 50px;" rows = "6" cols = "40" id = "comment"></textarea><br />
   <input type = "text" placeholder="Enter Maximium 100 Words" id = "alertid" value = "10">
   <input  type = "submit" name = "submit" value = "Comment">
</form>

最佳答案

尝试将此添加到表单onsubmit =“ return commitform();”

 function submitform(){
    var comment = $("#comment").val();
    var alertid = $("#alertid").val();
    $.ajax({
        type: "POST",
        //url: "ana.php",
        data:{cmt:comment,alert_id:alertid}
    }).done(function( result ) {
        $("#msg").html( result );
    });
    return false;
  }
