我有一个php文件,它包含一个textfiled和submit按钮,div和下面是代码
page1.php中
<form name="form1" method="post">
<input type="text" name="email1">
<input type="submit" name="submit" value="send" class="submit_class">
<div class="suc_box">You have Entered</div>
</form>
if($_POST['submit']) {
$v1 = $_POST['email1'];
// $query1 = here some code to insert into database
if($query1 > 0){
//here i want to display the div `suc_box`.. Here how i can show that div
}
}
和jQuery代码:
$(document).ready(function(){
$('suc_box').hide();
$('suc_box').click(function(){
$(this).hide();
});
});
问题:如何在表单插入数据库后提交表单时显示/显示suc_box
?

您可以使用AJAX轻松完成。你有一个带有表单的php文件和另一个用于处理数据的文件:
<强> // form_file.php 强>
<form id="my_form" onsubmit="validateform();">
<input type="text" name="email1" />
<input type="submit" value="OK" />
</form>
<div class="suc_box"></div>
<script>
$(document).ready(function(){
$('.suc_box').click(function(){
$(this).hide();
});
$('#my_form').submit(function(){
var data = $(this).serialize();
$.post('process.php',data,function(return_data){
$('.suc_box').html(return_data);
});
return false; //cancel the 'real' submit
});
});
</script>
<强> // process.php 强>
<?php
$email = mysql_real_escape_string($_POST['email1']);
//write data to DB
if($succeeded) {
echo 'You have Entered';
} else {
echo 'Something went wrong, try again!';
}
这是未经测试的,但你明白了。
验证电子邮件字段
function validateform(){
if (!/^\S+@\S+\.\w+$/.test(document.sweetform.Email.value)) {
alert("Not a valid e-mail address");
return false;
}
else {
return true;
}
}

如果你说得对,你可以做到这一点,但我建议你调查ajax做你想做的事情
<div class="suc_box">
You have Entered
</div>
</form>
<?php
if($_POST['submit'])
{
$v1 = $_POST['email1'];
// $query1 = here some code to insert into database
if($query1 > 0){
?>
<script type="text/javascript">
$('suc_box').show();
</script>
<?php
}
}
?>
