I have this input repeating based on my items ['1','2'], then ng-model for input:
<form id="register-form" form ng-submit="successbloodstock.updateRemark()" >
<div class="input-group input-group">
<div class="input-group-addon" style="width:130px">
<small>EXPIRATION DATE</small>
</div>
<input class="form-control" type="date" name="expiry_date"
ng-model="newExpiry" required>
</div>
</form>
but after I submit the form it doesn't show the ng-model as array:
.controller('successbloodstockCtrl', function($scope,$timeout,$location,$route,$routeParams,$http) {
var app = this;
app.number=['asdf','asadf'];
app.updateRemark = function() {
var userObject = {};
userObject.expiry_date = $scope.newExpiry;
console.log($scope.newExpiry[$index])
}
}
this gives me undefined

I am new in node js and trying to integrate single file upload using dropzone js. I want to upload image before submitting form. I have managed to call the upload action before submitting.
Here is my html code:
<form id="add_user" name="add_user" class="form-horizontal" action="/add-new-user" method="POST">
<div class="directory-bg text-center">
<div class="directory-overlay">
<span id="imageuploader">
<input name="profileimg" id="profileimg" type="hidden" value="">
<img id="ws_user_avatar" class="rounded-circle thumb-lg img-thumbnail dropzone" data-thumb="public/assets/images/users/user.png" src="public/assets/images/users/user.png" alt="Generic placeholder image">
<!--<div class="fallback">
<input name="image" id="image" type="file">

</div>
</div>
<div class="directory-content p-4">

Here is the js code to handle dropzone event
Dropzone.autoDiscover = false;
var myDropzone = new Dropzone(".dropzone", {
url: '/upload-image',
autoProcessQueue: false,
uploadMultiple: false,
maxFiles:2,
maxFilesize: 2,
createImageThumbnails:false,
hiddenInputContainer: "img.rounded-circle",
init: function(file) {
var prevFile = null;
this.on("addedfile", function(file) {
var $this = this;
setTimeout(function () {
if(file.status == "error"){
alert(file.previewTemplate.innerText);
} else {
if(prevFile){
$this.removeFile($this.files[0])
}
prevFile = file;
$("#user_avatar").attr('data-imgname', file.name);
previewImage($this);
}
}, 10);
});
}
});
function previewImage(input){
let fileReference = input.files && input.files[0];
if(fileReference){
var reader = new FileReader();
reader.onload = (event) => {
document.getElementById('user_avatar').src = event.target.result;
}
reader.readAsDataURL(fileReference);
}
}
$(document).on('click','#btn_submit', function(e){
e.preventDefault();
if(myDropzone.getQueuedFiles().length > 0){
myDropzone.processQueue();
} else {
$("#add_user").submit();
}
});
Here is the post handler code in router.js file:
const express = require('express');
const router = express.Router();
router.post('/upload-image', function(req, res){
console.log('requested inage',req.files.file.path);
// fs.readFile(request.files.file.path, function(err, data) {
// var newPath = __dirname + "/public/img/xspectra/customlogo.png";
// fs.writeFile(newPath, data, function (err) {
// console.log("Finished writing file..." + err);
// response.redirect("back");
// });
// });
});
When the dropzone myDropzone.processQueue() function called, I get an error message in the post handler function TypeError: Cannot read property 'file' of undefined.
Can anyone suggest me where I am doing wrong?
Many Thanks!
That means that the file uploaded didn't properly make it to your web server. Are you using express-fileupload on the nodejs side to handle the uploads?
If so, I recommend checking out this link on a really great tutorial
I'm trying to create a google form with react,
I have been creating all the questions as a components
if (props.type == "text") {
return (
<div className="box">
<h3 className="">{props.qustion}</h3>
<input className="short-text" placeholder="Your answer" id={"text"+props.id} name={"q"+props.id} type="text" onChange={updateField}/>
</div>
)
}
else if (props.type == "choice") {
return (
<div className="box">
<h3 className="">{props.qustion}{props.requre? <label className="requir">*</label>:""}</h3>
{props.answer.map(ans=>(
<div key={ans}>
<input className="radio" type="radio" id={ans} name={"radio"+props.id} value={ans} required={props.requre} onChange={updateField}/>
<label htmlFor={ans}>{ans}</label>
</div>
))
}
</div>
)
and I have been creating a form on the app file and put the components inside him,
return (
<div className="App">
<FormTitle/>
<form>
{
error? <h1>the sorce not found</h1>:data.map((item) =>(<Qustion qustion={item.question} type={item.type} requre={item.requre} id={item.id} answer={item.answares} key={item.id} />))
}
<div className="submit-right">
<input className="submit-button" type="submit" value="Submit" />
</div>
</form>
</div>
);
how to get all the form data as an object to create a post request ??
Try this function at start of the file where the form is
const formSubmit = (event) => {
event.preventDefault();
var data = new FormData(event.target);
let formObject = Object.fromEntries(data.entries());
console.log(formObject);
}
and in the form use this onSubmit={formSubmit}
<form onSubmit={formSubmit}>
<any element or components>
</form>
entries is not a function you can just reach it
const formSubmit = (event) => {
event.preventDefault();
var data = new FormData(event.target);
let formObject = Object.fromEntries(data.entries);
console.log(formObject);
}
My problem is I got an unexpected error at the browser end that says Cannot read property 'heading' of null
also marks this error at the client page file like about.ejs and showing; in the snap attached
I have provided all the required codes related to this. I reviewed multiple times to find for what or to where the actual errror originated but did not able to fix it.

here is my router.js file
router.get('/admin/about',serverController.isAuthenticated,serverController.about)
router.post('/admin/about',serverController.isAuthenticated,serverController.about_post)
This is also my controller file
exports.about = async function(req,res){
res.render('server/about', {
about : await aboutCollection.findOne()
})
}
exports.about_post = function(req,res){
let about = new About(req.body)
about.create().then(async()=>{
res.redirect('/admin/about')
}).catch(()=>{
res.send('404')
})
}
and finally this all about my model of about page
const aboutCollection = require('../db').db().collection('about')
const objectId = require('mongodb').ObjectID
const About = function(about){
this.about = about
}
About.prototype.create = function(){
return new Promise(async(resolve,reject)=>{
await aboutCollection.updateOne({}, {$set :
{
heading : this.about.heading,
subheading : this.about.subheading,
content : this.about.content
}
})
resolve()
})
}
module.exports = About
it's because about sent value of none at the ejs tag i mean
<%= about.heading%>
Do,
exports.about = async function(req,res){
res.render('server/about', {
about : await aboutCollection.find().toArray()
})
}
Instead of,
exports.about = async function(req,res){
res.render('server/about', {
about : await aboutCollection.findOne()
})
}
In my case, I did this; after trying then see error has gone.
I have an angular form with text fields and want to add am option for uploading image in the same form. I'm stuck with the latter.
The angular form contains html tag to upload the file. Once the file is uploaded the uploaded file's name is displayed in the input field.

<!--form to create new blog-->
<form #blogForm="ngForm" (ngSubmit)="Save(blogForm);">

window.confirm('Want to Publish?');
this.blogservice.Save(blogForm).subscribe(response => {

this.router.navigate(['/dashboard']);

}
}
//function to display selected image in the input field

console.log(img1);
if(img == undefined) {
this.imageFile = 'Upload an image';
} else {
this.imageFile = img;
}
}
}
Need to save file along with form submission
Here's a JavaScript script which will read your data from input and display it :
<input type='file' accept='image/*' onchange='openFile(event)'><br>
<img id='output'>
<script>
var openFile = function(event) {
var input = event.target;
var reader = new FileReader();
reader.onload = function(){
var dataURL = reader.result;
var output = document.getElementById('output');
output.src = dataURL;
};
reader.readAsDataURL(input.files[0]);
};
</script>
It come from the documentation of FileReader.
With that you should be able to store the input wherever you want and store the path inside of your MongoDB collection.
Else if you want to use Angular plugins, here's one that could be useful for you :

I am trying to update the records form a table by using Sequelize.
Unfortunately, the id of the event I am trying to update seems to be undefined. How can I send it correctly?
The block of code I have in my controller looks like this:
router.get('/edit/:eventid', function(req, res) {
var eventid = req.params.eventid;
Event.findById(req.params.eventid).then(function(event) {
eventid= event.eventid;
title= event.title;
description= event.description;
availabletickets=event.availabletickets;
date= event.date;
newDate= date.toString();
newdate= newDate.substring(0,21);
console.log(eventid);
}) .then(function() {
res.render('eventEdit', {
eventid: eventid,
pagetitle: ' Edit Event',
title: title,
description:description,
availabletickets:availabletickets,
newdate: newdate,
});
})
.catch(function(error) {
res.render('error', {
error: error
});
});
});
router.post('/edit', function(req, res){
var eventid = req.body.eventid;
var title = req.body.title;
var description = req.body.description;
var availabletickets= req.body.availabletickets;
var date = req.body.date;
console.log( eventid); //this returns undefined.
console.log('title, description, availabletickets, date);
const newData = {
title: title,
date: date,
description: description,
availabletickets: availabletickets
};
Event.update(
newData,
{
where:{
eventid:eventid
}
}
).then(function() {
console.log("Event updated");
res.redirect('/events');
}).catch(e => console.error(e));
});
Although, the HTML file,where the user introduces the values when editing the events, looks like this:
<div class="container">
<h2><%= pagetitle %> </h2>
<form method="post" action="/events/edit">
<div class="container">
<div class="col-md-12 ">
<div class="row">
<div class="col-md-12 ">
<input class="form-control" type="text" name="title" id="title" value="<%= title %>" placeholder="Titlu Eveniment" required="true">
<p style="color:#8B0000;"><small>*This field is mandatory</small></p>
<textarea rows=7 class="form-control" type="text" name="description" id="description" placeholder="Descriere Eveniment"><%= description %></textarea> <br>
<input class="form-control" type="text" name="availabletickets" id="availabletickets" value="<%= availabletickets %>"> <br>
<label> Data:<%= newdate %> </label> <br/>
<label>Cahnge event date:</label>
<input class="form-control" type="date" name="date" id="date" style="width:190px;" ><br>
<button class="btn" id="addValue" style="background-color:#8B0000; color:white;">Save</button>
<button class="btn btn-warning">Cancel</button>
</div>
</div>
</div>
</div>
</form>
</div>
You get the eventid as undefined because req.body doesn't contain the eventid (it's not passed from the client side). To pass it from the client side you have to add an input having the name="eventid" attribute.
In the EJS template you need to render the eventid value as a hidden input (<input type="hidden" ...)
You can do that by added in your form this line:
<input type="hidden" value="<%= eventid %>" name="eventid" />
This is the updated form code:
<div class="container">
<h2><%= pagetitle %> </h2>
<form method="post" action="/events/edit">
<input type="hidden" value="<%= eventid %>" name="eventid" />
<div class="container">
<div class="col-md-12 ">
<div class="row">
<div class="col-md-12 ">
<input class="form-control" type="text" name="title" id="title" value="<%= title %>" placeholder="Titlu Eveniment" required="true">
<p style="color:#8B0000;"><small>*This field is mandatory</small></p>
<textarea rows=7 class="form-control" type="text" name="description" id="description" placeholder="Descriere Eveniment">
<%= description %>
</textarea>
<br>
<input class="form-control" type="text" name="availabletickets" id="availabletickets" value="<%= availabletickets %>">
<br>
<label> Data:
<%= newdate %>
</label>
<br/>
<label>Cahnge event date:</label>
<input class="form-control" type="date" name="date" id="date" style="width:190px;">
<br>
<button class="btn" id="addValue" style="background-color:#8B0000; color:white;">Save</button>
<button class="btn btn-warning">Cancel</button>
</div>
</div>
</div>
</div>
</form>
