How can I get the new value of an input with jquery

So I have these two input fields written in html:
<div class="row">
<div class="col-md-12 form-group">
<label>Name</label>
<input type="text" name="doc name" class="form-control " id="doc-name">
</div>
</div>
<div class="row">
<div class="col-md-12 form-group">
<label>Number</label>
<input type="text" name="doc number" class="form-control " id="doc-number">
</div>
</div>
And I have some jquery code that returns me an error if either of the input fields remain empty:
if($('#doc-name').val() == '' || $('#doc-number').val =='') {
return false //this is completed with the actual error script but isn't important to the current issue
}
The issue that I actually have is that even after I complete the input fields, the .val() command still return an empty string, it is not returning what I actually wrote in those inputs. .html() or .text() also return something empty. Can you please point me in the right direction ?

Not sure if this is what you mean. But I've created a sample here where every click event it will get the value of the input fields.
<input type="text" id="name"/>
<input type="text" id="number"/>
<button id="getvalue">Get value</button>
Here's the js
$(document).ready( function(){
$('#getvalue').click( function() {
var nameVal = $('#name').val();
var numVal = $('#number').val();
if(nameVal == '' || numVal == ''){
alert('Empty fields.')
}else{
alert('Name is ' + nameVal + ' and Number is ' + numVal);
}
});
});
You need to have a trigger event in order for javascript to communicate with your html elements. In this case we are using a click event through button element.
Here's a working sample

It should be '#doc-name' and '#doc-number':
if ($('#doc-name').val() == '' || $('#doc-number').val() == '') {
alert('Error');
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="row">
<div class="col-md-12 form-group">
<label>Name</label>
<input type="text" name="doc name" class="form-control " id="doc-name">
</div>
</div>
<div class="row">
<div class="col-md-12 form-group">
<label>Number</label>
<input type="text" name="doc number" class="form-control " id="doc-number">
</div>
</div>

When you return false from an event handler it prevents the default action for that event and stops the event bubbling up through the DOM. That is, it is the equivalent of doing this:
if($('#doc-name').val() == '' || $('doc-number').val == '') {
alert('ok');
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="row">
<div class="col-md-12 form-group">
<label>Name</label>
<input type="text" name="doc name" class="form-control " id="doc-name">
</div>
</div>
<div class="row">
<div class="col-md-12 form-group">
<label>Number</label>
<input type="text" name="doc number" class="form-control " id="doc-number">
</div>
</div>

It depends on where/when you are calling that piece of code. In the example below it will execute on pressing a submit button.
https://jsfiddle.net/wy8z7b2k/
$('#submit').click(function(e) {
if ($('#doc-name').val() == '' || $('#doc-number').val() == '') {
console.log('returning false');
return false //this is completed with the actual error script but isn't important to the current issue
}
});
<div class="row">
<div class="col-md-12 form-group">
<label>Name</label>
<input type="text" name="doc name" class="form-control " id="doc-name">
</div>
</div>
<div class="row">
<div class="col-md-12 form-group">
<label>Number</label>
<input type="text" name="doc number" class="form-control " id="doc-number">
</div>
</div>
<div class="row">
<div class="col-md-12 form-group">
<button id="submit">Submit</button>
</div>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>

Use js or jQuery to make icon linked to fieldset once it is activated

I am using a bootstrap template I found online to create a simple multi-step form. The template has some icons across the top that identify where the user is in the form completion process. Once they complete the form step and select the next button, the icon map at the top advances to the next step and the previous step is now activated (color changed).
I want to be able to make these icons an active link once the user has completed the step so they can quickly navigate back to a previous step (fieldset) by clicking on the icon. If they have not yet completed the step, then the icon link should not be active. How can I make the icons an active link to their associated steps once they have been activated? Below is my html and js and here is my jsfiddle link: https://jsfiddle.net/93r5y1g3/5/.

});

Previous steps are marked with the class .activated.
So you may add an event handler which triggers the previous button like this:
$(document).on('click', '.f1-step.activated .f1-step-icon', function() {
$('.f1-buttons .btn.btn-previous').trigger("click");
});

disable an input if another input is clicked

I have three sections in a form, the first one contains one input and the second contains three inputs and the third contains a checkbox. How to
disable the two sections if checkbox is checked

I must have only one active section everytime.
What I did is not the solution because there is a problem in the second section. if only one input is empty in this section all the other inputs are enabled. any one can help me please.

It sounds like you may want try the focus listener instead of the on Blur listener.

The second element seems to work when I entered in values for all of the fields. It looks like it's checking the length of what was entered.

Allow only x number of form fields to be filled in

I have a very noob question, I have a form with input fields. The form has 10 fields, and the user needs to enter from 1-3 (one being most preferred, to 3 being last choice). After 3 have been filled, I want to either disable all other fields, or just disallow any further input and give an error.
I've got the counting up working, but i can't restrict or pop an error.
here's the code,
jQuery(document).ready(function($){
$("#choices").on('keyup change', function() {
var maxAllowed = 3;
var number = 0;
$(this).find('input, textarea').each(function () {
//if (number < maxAllowed && this.value !== '')
if (this.value !== '')
{
$('.input_count').val(number++);
}
});
});
});

any thoughts would be really appreciated. Thanks in advance.

jQuery(document).ready(function($){
$("#choices").on('keyup change', function() {
var maxAllowed = 4;
var number_done = 0;
$(this).find('input, textarea').removeAttr('disabled');
$(this).find('input, textarea').each(function () {
//if (number < maxAllowed && this.value !== '')
if (this.value !== '')
{
$('.input_count').val(++number_done);
}
});
if( number_done >= maxAllowed){
$(this).find('input,textarea').filter(function(){
if($(this).val()== '')
return true;
return false;
}).attr('disabled', 'disabled');
}
});
});
Here the max allowed is set to 4.because of you counter field.Which should be ingnored i think for the test purpose.Once this field is removed the maxallwoed can be set as 3

Try this code. I have found number of fields filled using filter function and disabled other fields using each, when the maximum number of fields allowed are filled. JSFiddle
jQuery(document).ready(function($){
$("#choices").on('keyup', function() {
var maxAllowed = 3;
var els = $(this).find('input, textarea');
var elsFilled = els.filter(function(i,el){ return el.value!="" }).length;
if(elsFilled==maxAllowed)
els.each(function(i,el){ if(el.value=="") el.disabled = true; });
else
els.each(function(i,el){ if(el.value=="") el.disabled = false; });
});
});

Form field values sum in jQuery

I can't seem to get this to work for a project I'm doing. Basically I'm trying to get the values in the "Revenue" fields to total at the bottom in the "Total Revenue" field.

You could tidy the code up a little:
function SetupInput(obj,output,sumfunction){
$(obj).keyup(function(){
var n = parseInt($(this).val());
var n = this.value.replace(/,/g, "");
if(n <= 155000) {
$(output).val(numberWithCommas((n/100*70).toFixed(0)));
}
else if(n <= 175000) {
$(output).val(numberWithCommas((n/100*75).toFixed(0)));
}
else {
$(output).val(numberWithCommas((n/100*80).toFixed(0)));
}
sumfunction();
});
}
SetupInput($('#AprilInput')[0],$('#AprilOutput')[0],calculateSum);
SetupInput($('#MayInput')[0],$('#MayOutput')[0],calculateSum);
SetupInput($('#JuneInput')[0],$('#JuneOutput')[0],calculateSum);
function numberWithCommas(x) {
return x.toString().replace(/\B(?=(?:\d{3})+(?!\d))/g, ",");
}
function calculateSum() {
var sum = 0;
//iterate through each textboxes and add the values
$(".form-control1").each(function() {
//add only if the value is number
var value=this.value.replace(',','');//remove ','
if(!isNaN(value) && value.length!=0) {
sum += parseFloat(value);
console.log(this.id,sum);
}
});
//.toFixed() method to roundoff the final sum
$("#TotalOutput").val(sum.toFixed(0));
}
Check out the jsfiddle: http://jsfiddle.net/2jY6P/43/

You are looping though Output tag. Change it to .form-contol:
$(".form-control").each(function() { /* ... */ }
And not .html, but .val():
`$("#TotalOutput").val(sum.toFixed(0));`

i edited you code: http://jsfiddle.net/2jY6P/38/
changed:
$(document).ready(function(){
//iterate through each textboxes and add keyup
//handler to trigger sum event
$("input[name='Output']").keyup(function(){
calculateSum();
});
});
function calculateSum() {
var sum = 0;
//iterate through each textboxes and add the values
$("input[name='Output']").each(function() {
//add only if the value is number
if(!isNaN(this.value) && this.value.length!=0) {
sum += parseFloat(this.value);
}
});
//.toFixed() method to roundoff the final sum
$("#TotalOutput").val(sum.toFixed(0));
}
$('Output') should be input $("[name='Output']")
$("#TotalOutput").html(sum.toFixed(0));
should be $("#TotalOutput").val(sum.toFixed(0));

I put some changes in
http://jsfiddle.net/2jY6P/39/
