i have a dynamic form which lets you add and remove inputs. The issue is what even though it works visually, when submitting the form i wont get the values from inputs created by the JS function. If you need anything else let me know as this is about the last implementation to the website
Any ideas as to why? i leave my code below
The html:
<div class="form-container" id="form-container">
<div class="title-title">
<h3 class="recipe-pretitle">Recipe for</h3>
<form action="/recipes/create" enctype="multipart/form-data" method="POST">
<div>
<label for="title">
<input name="title" type="text" id="title" placeholder="Name of dish">
</label>
</div>
</div>
<div class="description-container">
<label class="description-label" for="description">A brief description of your dish: <br> (max 80char)</label>
<textarea name="description" type="text" id="description" cols="30" rows="5"></textarea>
</div>

your HTML is not valid, form element is not properly closed, move closing form tag outside button container, and form opening tag a level up
this should work, and now you probably need to modify styles and rearrange some elements, so you need to see to it that the form and HTML is valid, and adapt styles accordingly:
<div class="form-container" id="form-container">
<form action="/recipes/create" enctype="multipart/form-data" method="POST">
<div class="title-title">

<label for="title">
<input name="title" type="text" id="title" placeholder="Name of dish">

</div>
</div>
<div class="description-container">
<label class="description-label" for="description">A brief description of your dish:
<br> (max 80char)</label>
<textarea name="description" type="text" id="description" cols="30" rows="5"></textarea>
</div>

I would like to add one Item if the button is clicked.
I have the following template:
const Item = ({
i
}) => `
<div class="additional-guest mb-3">
<hr>
<div class="row">
<div class="col-12 col-md">
<div class="form-group">
<label for="name_${i}" class="control-label">Name</label>
<input id="name_${i}" type="text" placeholder="Name" class="form-control" name="additional_guest[${i}][name]">
</div>
</div>
<div class="col-12 col-md">
<div class="form-group">
<label for="telephone_${i}" class="control-label">Telefonnummer</label>
<input id="telephone_${i}" type="text" placeholder="Telefonnummer" class="form-control" name="additional_guest[${i}][telephone]">
</div>
</div>
</div>
</div>
`;
var e = document.getElementsByClassName('additional-guests');
document.getElementById('new-guest-button').addEventListener('click', function(ev) {
console.log("klick");
var r = document.getElementsByClassName('additional-guest').length;
//e[0].innerHTML = [{ i: e.length}].map(Item).join(''); //works only once
e[0].append([{
i: r
}].map(Item));
}, false);
<div class="additional-guests ml-3">
</div>
<div class="form-group">
<button type="button" id="new-guest-button" class="btn btn-secondary btn-block">
Weiterer Gast
</button>
</div>
The <e[0].innerHTML>-Part works. But only once. I can add only one new Item because the further is overwritten. The append-Part is also not working. It writes the Item as text so it is not rendered. How can I add the template multiple times?
Use insertAdjacentHTML:
e[0].insertAdjacentHTML('beforeend', Item({i: r}));
const Item = ({
i
}) => `
<div class="additional-guest mb-3">
<hr>
<div class="row">
<div class="col-12 col-md">
<div class="form-group">

</div>
<div class="col-12 col-md">
<div class="form-group">
<label for="telephone_${i}" class="control-label">Telefonnummer</label>
<input id="telephone_${i}" type="text" placeholder="Telefonnummer" class="form-control" name="additional_guest[${i}][telephone]">
</div>
</div>
</div>
</div>
`;
var e = document.getElementsByClassName('additional-guests');
document.getElementById('new-guest-button').addEventListener('click', function(ev) {
console.log("klick");
var r = document.getElementsByClassName('additional-guest').length;
console.log(r);
e[0].insertAdjacentHTML('beforeend', Item({
i: r
})); // geht aber nur einmal
}, false);
<div class="additional-guests ml-3">
</div>
<div class="form-group">
<button type="button" id="new-guest-button" class="btn btn-secondary btn-block">
Weiterer Gast
</button>
</div>
On every click I create new div, append the Item and then append the div into e[0].
const Item = i => `
<div class="additional-guest mb-3">
<hr>
<div class="row">
<div class="col-12 col-md">

var e = document.getElementsByClassName('additional-guests');
var fieldsFlag = 0;
document.getElementById('new-guest-button').addEventListener('click', function(ev) {
var div = document.createElement('div');

fieldsFlag++;
e[0].append(div);

I got a problem with my validation of textboxes.
I am trying to get something like this.
Click on the button, give a message when something is not filled in, while you fill the empty textbox, the 1 message of that textbox should dissapear.
If you click the button again, with 1 empty textbox, only the message of that textbox should appear.
If you click it twice with nothing filled, it should only appear once ...
I messed something up here ...
can someone get me on again?
Thank you in advance!

I feel like your approach is a little more complicated than it needs to be.. See my attempt below
function valideer(current) {
var ids = ['naam', 'voornaam', 'straatnr', 'postgem', 'telgsm', 'email'];
var str = '<ul>';
ids.forEach(function(id) {
var el = document.getElementById(id);
if (el.value === '' && el !== current) {
str += "<li><b>" + id + ": </b>verplicht veld</li>";
}
});
str += '</ul>';
var outputDiv = document.getElementById("msgbox1");
outputDiv.innerHTML = str;
}
function handleFormSubmit(ev) {
ev.preventDefault();
valideer();
return false;
}

Some notes and observations:
Since the only check being used for validation is if it contains, an empty string, I have generalised the valideer function to iterate and operate on a given array of ids. This can be made even better by querying for inputs on your form using a DOM query and handling it like that.
You have added a lot of inline event handlers in your dom.. Some of them are redundant and not really needed. For example, having a simgle onsubmit on your form element should suffice (no need to add it for every input inside the form)
You were using a global variable list2 this is what was causing the repeated entries each time you click the button. Localising the scope would fix that (by moving it inside a function)
You're already using required property, which means you no longer need a js function to validate if your inputs are empty or not.
You should also notice that list2 is a global variable, which means that you should clean it at the end of every valideer() invocation.
All in all, you code seems very verbose .. try to find a better way to express you needs.
I am working with a chat application. I need to put an input search box for the user to search for a friend from his friends list. I have written code to get ID values and and trigger it onkeyup. However, I am getting an uncaught reference error of function(name) is undefined. Here I am getting users list from server side using socket code.
Function in JS file
$scope.searchFn = function () {
var input, filter, ul, li;
input = document.getElementById("input");
// filter = input.value.toUpperCase();
ul = document.getElementById("list");
li = ul.getElementsByTagName("li");
for (i = 0; i < li.length; i++) {
a = li[i].getElementsByTagName("a")[0];
if (a.innerHTML.toUpperCase().indexOf(filter) > -1) {
li[i].style.display = "";
} else {
li[i].style.display =
"none";
}
}
}

Don't use function expression $scope.searchFn = function () {}.
Function expressions in JavaScript are not hoisted.
Use named functions to avoid such cases
function searchFn() {...}
You are not using an angular directive for triggering the keypress event. The "onkeypress" is an html attribute so any function declared on $scope will not be accessible. You should use ng-keypress directive.
Before:
<input id="input" class="form-control" name="browser" placeholder="Search friend.." ng-model="search" onkeypress="searchFn()">
After:
<input id="input" class="form-control" name="browser" placeholder="Search friend.." ng-model="search" ng-keypress="searchFn()">
I have an app where I want to add extra elements to an item in an array, I have created a fiddle of what I'm trying to achieve.
So the user starts the app, they click next fill in some details of an item and a description, they then should click next and fill in a price for the item(this is where I'm stuck). This example works up to a point, as in whenever I try and implement the price part I seem to be getting it wrong. You'll see once I click next the item is added to the array, however how do add more elements to the current item in the array. In case I've not made sense the logic should be:
Start
Page one (enter name and description)
Page two (enter price)
I understand I could do this all on one page but I don't want to I want knockout to be able to add a price after the name and description page. I would also like to be able to go back and amend the item. Can you anybody help in seeing what I should be doing next?
When I insert the name and description, do I have to also make an empty element in the array for the price? Then once the price is entered somehow insert this into the price element in the array? Not sure how/if this should be implemented.
This is my first knockout app so I be surprised if what I've actually done is correct, any help or pointers gratefully received :)
My code is below:
$(function() {
var main = new stuff();
ko.applyBindings(main, $('#ko')[0]);
});
function Item(data) {
this.itemname = ko.observable(data.itemname);
this.itemdescription = ko.observable(data.itemdescription);
this.itemenabled = ko.observable(data.itemenabled);
}
function stuff() {
var self = this;
self.items = ko.observableArray([]);
self.newItemName = ko.observable();
self.newItemDescription = ko.observable();
self.newItemEnabled = ko.observable();
// Operations
self.addItem = function() {
self.items.push(new Item({
itemname: this.newItemName(),
itemdescription: this.newItemDescription(),
itemenabled: this.newItemEnabled()
}));
};
};
//jquery stuff

Ok, so I have added a new observable to track the page number along with basic functions to increment/decrement the number then I simply add the new item after the price has also been added.
$(function() {
var main = new stuff();
ko.applyBindings(main, $('#ko')[0]);
});
function Item(data) {
this.itemname = ko.observable(data.itemname);
this.itemdescription = ko.observable(data.itemdescription);
this.itemenabled = ko.observable(data.itemenabled);
this.price = ko.observable(data.itemprice);
}
function stuff() {
var self = this;
self.items = ko.observableArray([]);
self.newItemName = ko.observable();
self.newItemDescription = ko.observable();
self.newItemEnabled = ko.observable();
self.newItemPrice = ko.observable();
self.page = ko.observable(1);
// Operations
self.next = function() {
if (self.page() === 2) {
self.addItem();
}
self.page(self.page() + 1)
}
self.back = function() {
if (self.page() == 1) {
$("#panel1").hide(500);
$("#page1").hide(500);
$("#start").show(500);
}
self.page(self.page() - 1);
}
self.addItem = function() {
self.items.push(new Item({
itemname: this.newItemName(),
itemdescription: this.newItemDescription(),
itemenabled: this.newItemEnabled(),
itemprice: this.newItemPrice(),
}));
};
};
//jquery stuff
$('#start').on('click', function(e) {
$("#page1").show(500);
$('#panel1').css('visibility', 'visible').hide().fadeIn().removeClass('hidden');
$("#start").hide(500);
})

I have a Jquery function to activate and deactivate forms based off the current form. When I click on the submit button I can get the value of the activeform on the page load if I have it set to ID, but nothing off the second form. When I set it to class it doesn't seem to load any at all and I get no alert back when I click the submit. My jquery is as such:
<script>
$(document).ready(function() {
var activeform = "register";
$("#loginlink").click(function(e) {
var activeform = "login";
$("#login").show("blind", 1000);
$("#register").hide("blind", 1000);
})
$("#registerlink").click(function(e) {
var activeform = "register";
$("#register").show("blind", 1000);
$("#login").hide("blind", 1000);
})
$(".submit").click(function(e) {
e.preventDefault();
alert(activeform);
});
});
</script>
And the code for my forms:
<p>
<form id="register">
<div class='row'>
<div class="col-xs-4"></div>
<div class="col-xs-4">
<label for username><i class="fa fa-user"></i> Username</label>
<input class="form-control" type="text" id="username"></div>
<div class="col-xs-4"></div>
</div>
<div class="row">
<div class="col-xs-4"></div>
<div class="col-xs-4">
<label for password><i class="fa fa-key"></i> Password</label>
<input class="form-control" type="password" id="password"></div>
<div class="col-xs-4"></div>
</div>
<div class="row">
<div class="col-xs-4"></div>
<div class="col-xs-4">
<label for email><i class="fa fa-envelope"></i> Email</label>
<input class="form-control" type="text" id="email"></div>
<div class="col-xs-4"><i class="fa fa-info-circle" title="You may be notified of delayed or denied payments." data-toggle="tooltip"></i></div>
</div>
<div class="row">
<div class="col-xs-4"></div>
<div class="col-xs-4">
<label for submit><i class="fa fa-info" data-toggle="tooltip" title="By Registering you Agree to be Bound by our Terms of Service"></i></label>
<button type="button" class="btn btn-success form-control" class="submit">Register</button></div>
<div class="col-xs-4"></div>
</div>
</form>
<form id="login" style="display:none;">
<div class='row'>
<div class="col-xs-4"></div>
<div class="col-xs-4">
<label for username><i class="fa fa-user"></i> Username</label>
<input class="form-control" type="text" id="username"></div>
<div class="col-xs-4"></div>
</div>
<div class="row">
<div class="col-xs-4"></div>
<div class="col-xs-4">
<label for password><i class="fa fa-key"></i> Password</label>
<input class="form-control" type="password" id="password"></div>
<div class="col-xs-4"></div>
</div>
<div class="row">
<div class="col-xs-4"></div>
<div class="col-xs-4">
<br />
<button type="button" class="btn btn-success form-control" class="submit">Login</button></div>
<div class="col-xs-4"></div>
</div>
</form>

Last but not least. Here's a fiddle. :)

You were recreating the activeform variable every time in the click event. remove the var keyword. you already declared that as a global variable inside the document ready scope.
$(function(){
var activeform = "register";
$("#loginlink").click(function(e) {
activeform = "login";
$("#login").show("blind", 1000);
$("#register").hide("blind", 1000);
});
$("#registerlink").click(function(e) {
activeform = "register";
$("#register").show("blind", 1000);
$("#login").hide("blind", 1000);
});
$(".submit").click(function(e) {
e.preventDefault();
alert(activeform);
});
});
Also you need to make sure that you have the submit css class on both the login and register buttons
Here is a working sample
