Please help! I was trying to build a mini loan eligibility web app using JavaScript, but my problem is that the display result wasn't showing what it seems to show after clicking on the eligibility button.
Below are my HTML and JavaScript Code.
let Amount = document.querySelector("#amount").value;
let Duration = document.querySelector("#years").value;
let amt = parseInt(Amount);
let dura = parseInt(Duration);
let Message = document.querySelector("#result");
//const Income = parseInt(Amount.value);
//const Years = parseInt(Duration.value);
function eligibility(){
if(amt < parseInt(50000) ){
Message.textContent = "Please! You're not eligible for the loan";
// console.log('Try again')
} else if(amt >= parseInt(50000) ) {
Message.textContent = "Please Fill the form below and apply"
// console.log('Please Fill the form below and apply')
}
}
<html>
<form action="" role="form">
<div class="form-group">
<div class="input-group">
<span class="input-group-addon">
<span class="glyphicon glyphicon-plus"></span>
</span>
<input type="number" class="form-control" placeholder="Income" id="amount" required />
</div>

</div>
</div>
<button type="" class="btn btn-primary btn-block" onclick="eligibility()">Check Eligibility</button>
<div id="result">
</div>
</form>
</html>
The main issue was you need to declare those input values inside the function your calling on the button click. Or else they will all be set to the the value that they load up as (null)
I changed your some of your code and added comments throughout. Hope this helps

}

</body>
The values I want to show after the input is currently Name, Email, Address, ZIP and CVV. My CVV is giving me undefined when my other values are correct. I am not sure why
To set and get data from localStorage -
localStorage.setItem('variable_name', 'value');
localStorage.getItem('variable_name');
Please try to do this code.
<script>
function setData(){
if(typeof(Storage) !== "undefined"){
document.getElementById("name").innerHTML = localStorage.name;
document.getElementById("email").innerHTML = localStorage.email;
document.getElementById("adr").innerHTML = localStorage.adr;
document.getElementById("zip").innerHTML = localStorage.zip;
document.getElementById("cvv").innerHTML = localStorage.cvv;
}
}
</script>
why we are checking this condition, some browser does not support Web Storage
if(typeof(Storage) !== "undefined")
I found out my problem, my </form was placed wrongly. Sorry and thanks to everyone that helped!
I've created a clone function on html file. But there's a weird error in code. when I put two ending 'div' in same line, the JavaScript code just work fine. but when I beautify html code or put the last ending tag in another line, the JavaScript just doesn't work. please look at the commented line

}else{

this code works fine. but when I change the code into below lines, then the JavaScript just don't work at all -
<body>

function hide() {
document.getElementById('show').style.display = 'none';
}
function addElement() {
error.innerHTML = '';
let item = document.getElementById('myList').lastChild;
let cln = item.cloneNode(true);
document.getElementById('myList').appendChild(cln);
}
function removeIt() {
let list = document.getElementById('myList');
if(list.childNodes.length == 2){
error.innerHTML=`you cant delete the last input box`;
}else{
let length = list.childNodes.length;
list.removeChild(list.childNodes[length-1]);
}
}
</script>
lastChild is the last child node of any kind, including text nodes. By moving the closing </div> tag, you're adding a text node.
You could use lastElementChild instead to get only the last element in the list.
Here's a simplified example:
console.log(document.getElementById("container1").childNodes.length); // 2
console.log(document.getElementById("container2").childNodes.length); // 3
<div id="container1">
<div>x</div></div>
<div id="container2">
<div>x</div>
</div>
Side note: Your HTML is invalid. div elements cannot be direct children of ul elements. ul elements are expected to contain li elements as their only direct (element) children.
I am trying to add form validation using JavaScript. When I add
document.getElementById("one").setAttribute("ng-click", "insertData()");
to validateForm function, it does not work after I press the button.
When I move that line out of validateForm function it works, but does not perform form validation.

Ok, what you are trying to do is not how angularjs works; i suggest you to read angularjs form documentation, especially the Binding to form and control state chapter.
Your code seems a clash between jquery and angularjs, i suggest to you to re read angularjs phonecat tutorial or, even better, to try the new version of angular
You need to tell Angular that you've added an attribute, otherwise it doesn't work. When adding an attribute to your template file, Angular knows, but when adding it by setAttribute(), Angular has no idea.
In your controller, add the following two dependencies:
app.controller("controller", function($compile, $document, $scope, $http) {
//
});
Now, after adding the attribute to the element, you need to re-compile it:
$document.getElementById("one").setAttribute("ng-click", "insertData()");
// Try this:
$compile($document.getElementById("one"));
// If it doesn't work, or gives an error, try this:
$compile($document.getElementById("one"))($scope);
Note: I use $document, not document
Documentation for $compile
Note: I cannot really test if this works for your code, but it should at least point you in the right direction. Your problem is that Angular doesn't know you added the attribute.
I would like to create dynamically some input fields, that I used ng-repeat with ng-model. I meet some problems. ng-model without ng-repeat works correctly (transitPointStart). transits should work exactly the same, but they don't. What am I missing?
(link to plunker on the bottom)
transitPointStart:

Demo: Plunker
Some of the bindings in your HTML are not correct. You need to use interpolation (the {{ }} format) whenever you need to emit data from the model into the HTML.
For example, when assigning IDs, you have:
<input id="transit.fieldDateName" type="text" class="form-control" placeholder="e.g" name="transit.fieldDateName" ...
This should be:
<input id="{{transit.fieldDateName}}" type="text" class="form-control" placeholder="e.g" name="{{transit.fieldDateName}}" ...
Second, your ng-click syntax is not correct. You should not create the openCalendar expression in JavaScript, but in your HTML, like so:
<button type="button" class="btn btn-default" ng-click="openCalendar(transit.fieldDateName)">
I think your Plnkr is missing some scripts and/or steps to make the calendar work, but these changes will at least cause your openCalendar function to get called.
i have a field with 'add' and 'remove' field options and my problem is if someone click remove button at first time then there is nothing left. however i created a another button and hide it by this code.
$('#more_fields').hide();
is that possible to show this button when there is no field or no button with deleteMe class available
i'm using this code for delete fields.
$(document).on("click",".deleteMe", function(){
$(this).closest(".addform").remove();
});
var room = 1;
function add_fields() {
room++;
var objTo = document.getElementById('room_fileds')
var divtest = document.createElement("div");
divtest.innerHTML = '<div class="addform"><div class="input-group"> <label for="Services">Services '+room+'</label> <input type="text" class="form-control" id="Services" name="serve[]" style="max-width: 148px;" placeholder="Add Services"> <span class="input-group-btn" > <button class="btn deleteMe" style="">×</button> <button class="btn btn-success pull-right" onclick="add_fields();" type="button"><i class="fa fa-plus"></i></button> </span> </div></div>';
objTo.appendChild(divtest)
}
//]]>
$(document).on("click",".deleteMe", function(){
$(this).closest(".addform").remove();
});
$('#more_fields').hide();

on delete do like
room -= 1;
than if at some point you do
if(room===0) { /*here show your button */ }
I've noticed that you use ID for buttons like #err_quali, #Services... Don't. you're going to have load of duplicate IDs on the page which is wrong. Use classes instead.

var rooms = 1;
var c = 1;
var $roomsWrapper = $("#room_fileds"); // the parent
var $room = $(".input-group").clone(); // Store a group
$('#more_fields').hide();
$(".form-inline").on("click", ".deleteMe", function(ev) {
ev.preventDefault();
rooms -= 1;
$(this).closest(".input-group").fadeOut(300, function(){
$(this).remove();
});
$('#more_fields').toggle( !rooms );
}).on("click", ".addField, #more_fields", function(ev) {
ev.preventDefault();
rooms += 1;
c += 1;
var $klon = $room.clone();
$klon.find(".groupNum").text(c);
$roomsWrapper.append( $klon );
});
