redirect after .submit() form
提问by jclarke04
I have a HTML form which uses a div (submitme) to trigger the following code.....the code then uses the bValidator plugin to validate the form fields and then checks whether a honeypot field is blank before submitting the form....
我有一个 HTML 表单，它使用 div (submitme) 来触发以下代码......然后代码使用 bValidator 插件来验证表单字段，然后在提交表单之前检查蜜罐字段是否为空...... .
When I exclude the "window.location..." etc the .submit() works and posts the form through, however when including it; the validation/honeypot still works but no form submits.
当我排除“window.location...”等时，.submit() 工作并通过表单发布，但是当包含它时；验证/蜜罐仍然有效，但没有提交表单。
Im new to JQUERY and was wondering if theres something simple im missing or a better way to write the below:
我是 JQUERY 的新手，想知道我是否缺少一些简单的东西，或者是否有更好的方法来编写以下内容：
$("#submitme").click(function(){
if($('#right-body-div').data('bValidator').validate()) {
if ($("#honeypot").val() == "") {
$('#pgpost').submit();
window.location = "http://www.homepage.co.uk/thankyou";
return true;
}
window.location = "http://www.homepage.co.uk/nothankyou";
return false;
}
});
If possible id like to accomplish this without the use of AJAX/PHP.
如果可能，我想在不使用 AJAX/PHP 的情况下完成此操作。
Your thoughts would be much appreciated.
您的想法将不胜感激。

$('#pgpost').submit(function(e) { // this handles the submit event
if($('#right-body-div').data('bValidator').validate()) {
if ($("#honeypot").val() == "") {
/*
* url = $('#pgpost').val('action');
* data = $('#pgpost').serialize();
* $.post(url, data, function() {
* window.location = "http://www.homepage.co.uk/thankyou";
* });
*/
window.location = "http://www.homepage.co.uk/thankyou";
}
else {
window.location = "http://www.homepage.co.uk/nothankyou";
}
}
e.preventDefault();
return false;
/*
* the 2 lines above are meant to prevent the normal behaviour
* that the <form> would have (which is to submit via browser).
*
* e.preventDefault() is the jquery way prevent the normal behaviour
* return false is the legacy way to do it, you can use either or both
*
* the reason for which the code didn't validate your form is
* that e.prevenDefault() was only called inside the IF statement
* which means that it would only be called if the field was
* already in valid form. So basically if the form was invalid the normal
* behaviour is not prevented and the browser submits the form, if the form
* was valid the submit behaviour was prevented and the redirect was used.

});
$("#submitme").click(function(){
$('#pgpost').submit(); // this triggers the submit event
});
When handling the submit event via JavaScript you can:
通过 JavaScript 处理提交事件时，您可以：
- prevent normal behaviour always (our case):
- when form is valid you submit the datavia JavaScript and maybe you process it before submitting it;
- when the form is invalid you show error messages;
- prevent normal behaviour only when form is invalid:
- when the form is valid you allow normal behaviour (browser submits data);
- when the form is invalid you show error messages;
- 始终防止正常行为（我们的案例）：
- 当表单有效时，您通过 JavaScript提交数据，并且可能在提交之前对其进行处理；
- 当表单无效时，您会显示错误消息；
- 仅在表单无效时防止正常行为：
- 当表单有效时，您允许正常行为（浏览器提交数据）；
- 当表单无效时，您会显示错误消息；
Error messages in your case should state that honeypot is not supposed to be empty.
您的情况下的错误消息应该说明蜜罐不应该是空的。
It makes sense to prevent normal behaviour if: - you need to process the data before it is sent to the server (creating new values, changing present values; not validation); - you need to avoid a page refresh so you send via AJAX;
在以下情况下阻止正常行为是有意义的： - 您需要在将数据发送到服务器之前对其进行处理（创建新值、更改当前值；而不是验证）；- 您需要避免页面刷新，以便通过 AJAX 发送；
Just for validation it doesn't make sense to prevent the behaviour, because you can validate then allow the normal behaviour to continue.
仅仅为了验证，阻止行为是没有意义的，因为您可以验证然后允许正常行为继续。
