Hide Form After Submit
提问by qweqweqwe
I am attempting to hide my form after my submit button has been pressed using Jquery.
我试图在使用 Jquery 按下提交按钮后隐藏我的表单。
So far I have imported the Jquery library.
到目前为止，我已经导入了 Jquery 库。
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.2/jquery.min.js"></script>
Trying to attempt to hide the form using the class "form-fields." This class holds the whole form.
试图尝试使用“表单字段”类隐藏表单。这个类包含整个表单。
Trying to hide it like this:
试图像这样隐藏它：
<?php if (isset($_POST['process']) && ($_POST['process'] == 1)): ?>
<script type="text/Javascript">
$('#form-fields').hide();
</script>
This doesn't seem to be working. Any help would be appreciated.
这似乎不起作用。任何帮助，将不胜感激。

You need to hide the form using the submit event handler and need to remove the PHP condition <?php if (isset($_POST['process']) && ($_POST['process'] == 1)): ?>since it runs in the server side
您需要使用提交事件处理程序隐藏表单，并且需要删除 PHP 条件，<?php if (isset($_POST['process']) && ($_POST['process'] == 1)): ?>因为它在服务器端运行
What happens below is, we register an event handler which will get called when the form is submitted, and inside that the form is hidden
下面发生的事情是，我们注册了一个事件处理程序，它会在提交表单时被调用，并且在其中隐藏表单
<script type="text/Javascript">
$('#form-fields').submit(function(){
$(this).hide();
})
</script>

If the form sends users to the same pageafter clicking submit, it's probably easiest to do the hiding with php. Add this somewhere at the top of your file:
如果表单在单击提交后将用户发送到同一页面，则使用 php 进行隐藏可能最容易。将此添加到文件顶部的某处：
<?php $submitPressed = isset($_POST['process'] && $_POST['process'] == 1; ?>
You can then wrap anything you want to hide in the following tags:
然后，您可以将要隐藏的任何内容包装在以下标签中：
<?php if (!$submitPressed): ?>
<!-- form goes here -->
<?php endif; ?>
Note, this will only hide the form once the server has been notified; there might be a tiny delay after pressing submit.
请注意，这只会在服务器收到通知后隐藏表单；按下提交后可能会有一点延迟。
Otherwise, you'll want to use some jQuery bound to the submit event.
否则，您将需要使用一些绑定到提交事件的 jQuery。

$('form-fields').submit(function(){
var $this = $(this); // so we can use in ajax callback
$.ajax({
url: '/',
data: $(this).serialize(),
success: function(data){
if(data == true){
$this.hide(); //hide form if we got a true to return
}
}
});
return false; //stop default form submit
});
Same page...
同一页...
<?php
if(isset($_POST['process']) && ($_POST['process'] == 1)):
// do whatever processing
return true; //at the end so we can compare in ajax
endif;
?>

You can add the css property of that element to hidden on click..
$(function(){
$('form-fields').submit(function(){
$(this).css("visibility", hidden);
});
});
