[英]How to delete an error alert after a time in Pug
guys.伙计们。 I'm still learning express, and I am using Pug to view my elements in the browser.
我还在学习 express,我正在使用 Pug 在浏览器中查看我的元素。 I'm showing an error alert when a client tries to send a testimonial before to fill all information.
当客户尝试在填写所有信息之前发送推荐时,我会显示错误警报。 The problem is those alerts stay on the screen and don't disappear.
问题是那些警报停留在屏幕上并且不会消失。 I would like to make them disappear after a few seconds.
我想让它们在几秒钟后消失。
This is the code I'm using to send the errors to testimoniales.pug file.这是我用来将错误发送到 testimonales.pug 文件的代码。
const errores = [];
if(name.trim() === ''){
errores.push({message : 'The name is empty'});
}
if(mail.trim() === ''){
errores.push({message : 'The mail is empty'});
}
if(message.trim() === ''){
errores.push({message : 'The message is empty'});
}
* if(errores.length > 0){
//consult the testimonials that already exis
const testimoniales = await Testimonial.findAll();
//show the view with errors
res.render('testimoniales', {
page: 'Testimoniales',
errores,
name,
main,
message,
testimoniales
});*
}else{
//Save in the DATABASE
try {
await Testimonial.create({
name,
mail,
message
});
res.redirect('/testimoniales');
} catch (error) {
console.log(error);
}
}
This is the code to show the errors in my testimoniales.pug file.这是在我的 testimonales.pug 文件中显示错误的代码。
if(errores)
each error in errores
.alert.col.alert-danger.text-center= error.mensaje
So, all I want is to eliminate the alerts after 3 or 5 seconds.所以,我只想在 3 或 5 秒后消除警报。
You would need some client-side Javascript.您将需要一些客户端 Javascript。
Something like:就像是:
if (errores)
#errors
each error in errores
.alert.col.alert-danger.text-center=error.mensaje
And add, maybe after </body>
,:并添加,也许在
</body>
之后:
if (errores)
script.
setTimeout(()=>
document.getElementById("errors").style.display="none", 5000);
I'm still learning express
