Possibility to find a clicked number in a value using jQuery

I want to learn, can we find the same number in two input values.
For example:
<input type="hidden" id="multinumber" value="1,2,3,4,5">
<input type="hidden" id="justonenumber" value="3">
<div class="click">Click and test the same number</div>
JS
$(document).ready(function(){
$("body").on("click",".click", function(){
var multiple = $("#multinumber").val();
var single = $("#justonenumber").val();
});
});
When onClick event on the .click button then check the same number in the #multinumber and #justonenumber input values and get the result in an alert box.
Is there a way to do this ? Anyone can help me here please?

Just use indexOf or includes on your multiple string. :)
$(document).ready(function(){
$("body").on("click",".click", function(){
var multiple = $("#multinumber").val();
var single = $("#justonenumber").val();
var doesMultipleIncludeSingle = multiple.includes(single);
// OR
var doesMultipleIncludeSingle = multiple.indexOf(single) > -1;
});
});
As per the problem explained in the comment, it seems the requirement does involve splitting the array.
$(document).ready(function(){
$("body").on("click",".click", function(){
var multiple = $("#multinumber").val().split(',');
var single = $("#justonenumber").val();
var doesMultipleIncludeSingle = multiple.includes(single);
// OR
var doesMultipleIncludeSingle = multiple.indexOf(single) > -1;
});
});

You can get the value of first input box. Split it by , and check with .indexOf for the other input. If it's there, you can put the result in alert box like
$(".click").click(function(){
var x = $("#multinumber").val().split(",");
var y = $("#justonenumber").val();
if(x.indexOf(y) > 0){
alert(x.find(o=> o==y))
}
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<input type="hidden" id="multinumber" value="1,2,3,4,5">
<input type="hidden" id="justonenumber" value="3">
<div class="click">Click and test the same number</div>

is this what you want?
$(document).ready(function(){
$("body").on("click",".click", function(){
var multiple = $("#multinumber").val();
var single = $("#justonenumber").val();
if(multiple.indexOf(single) > -1) alert(single + " is found");
else alert(single + " isn't found");
});
});

populate input fields from php / javascript

How can I populate 50 html5 input fields from an external delimited "|" text file ("players.txt"):
Smith, Bob|Jones, James|Cavanaugh, Harvey|
I have input fields like so:
<input type="text" name = "N01" id = "I01">
<input type="text" name = "N02" id = "I02">
<script>
$jQuery.get('assets/players.txt', function(data) {
splitString = dataString.split("|");
$('#I01').val(splitString[0]);
$('#I02').val(splitString[1]);
$('#I03').val(splitString[2]);
});
</script>

Try getting html elements using jquery $ sign such as
$('#I01').val(splitString[0]);
$('#I02').val(splitString[1]);
$('#I03').val(splitString[2]);

You're currently referencing the wrong data variable dataString, instead reference data. Also, if you know your IDs are sequential, you can avoid writing 50 different lines of JS and run a for loop, for instance:
for(i=0; i<splitString.length; i++){
id = "#I0"+(i+1);
$(id).val(splitString[i]);
}

Don't set the value of each element individually, use a forEach loop.
Make sure to take into account string padding.
splitString.forEach((str, i) => {
document.querySelector('#I' + String(i).padStart(2, '0'))
.value = str;
});

let dataString = "Smith, Bob|Jones, James|Cavanaugh, Harvey|";
let splitString = dataString.split("|");
for (let i = 0; i < splitString.length; i++) {
$("#I0" + i).val(splitString[i]);
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="text" name="N01" id="I01">
<input type="text" name="N02" id="I02">

Example without ajax:
$(function(){
var splitString = 'Smith, Bob|Jones, James|Cavanaugh, Harvey';
splitString = splitString.split("|");
$('#playersInputs').empty();
$.each(splitString, function(i,v){
$('<input type="text" />')
.attr('name', 'N'+("0"+(i+1)).slice(-2))
.attr('id', 'I'+("0"+(i+1)).slice(-2))
.val(v)
.appendTo('#playersInputs');
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id='playersInputs'>
</div>
Example With ajax:
you must replace /path/to/your/text-file with the actual url
$(function(){
$.get('/path/to/your/text-file', function(data) {
var splitString = data.split("|");
$('#playersInputs').empty();
$.each(splitString, function(i,v){
$('<input type="text" />')
.attr('name', 'N'+("0"+(i+1)).slice(-2))
.attr('id', 'I'+("0"+(i+1)).slice(-2))
.val(v)
.appendTo('#playersInputs');
});
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id='playersInputs'>
</div>

Allow only number digits in input type regex. issue is i am able to type this(1.) , want to prevent it

MY CODE
function validate(e, id) {
var reg = new RegExp('^\\d+$');
if (reg.test($("#" + id).val())) {
var value = $("#" + id).val();
alert(value);
} else {
alert("fail");
}
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.0.0/jquery.min.js"></script>
<input name="input-type" type="number" id="number-input" oninput="validate(event,'number-input');">
This accept 1.(dot after any digits) value rest all is good.

You can try using <input type="tel" ...>. This way when user types 1. you will receive 1. only and not 1 and it will also open number keypad on mobile.
function validate(e, id) {
var reg = /^[0-9]*(\.(?=[0-9]+))*[0-9]+$/;
var value = $("#" + id).val();
if (reg.test(value)) {
console.log(value);
} else {
console.log("fail");
}
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.0.0/jquery.min.js"></script>
<input name="input-type" type="tel" id="number-input" oninput="validate(event,'number-input');">
You can also refer to How to get the raw value an <input type="number"> field? for more information in why 1. returns 1 and not 1.

It work as fallow:
1 pass
1. fail
1.1 pass
function validate(e, id) {
var value = $("#" + id).val() + "";
if (new RegExp('^[0-9]+\.[0-9]+$').test(value)
|| ((new RegExp('^[0-9]+').test(value) && !value.includes(".")))
) {
var value = $("#" + id).val();
alert($("#" + id).val() + "->" + value);
} else {
alert("fail " + $("#" + id).val());
}
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.0.0/jquery.min.js"></script>
<input name="input-type" type="text" id="text-input" oninput="validate(event,'text-input');">

Here is a code that might help you.In the below code when the user types . it is replaced by null.It only accepts digits.This is for input type="text".The variable currValue has the value of the input.
The search() method searches a string for a specified value, and returns the position of the match.The search value can be string or a regular expression.This method returns -1 if no match is found.
Then I am using .replace()
The replace() method searches a string for a specified value, or a regular expression, and returns a new string where the specified values are replaced.
Here I am replacing it with null if the regex doesn't match.The regex [^0-9] checks if not digit.
JSFIDDLE
Here is the code:
$(function() {
$('input').bind('keyup', function(event) {
var currValue = $(this).val();
if (currValue.search(/[^0-9]/) != -1) {
alert('Only numerical inputs please');
}
$(this).val(currValue.replace(/[^0-9]/, ''));
alert($(this).val());
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.0.0/jquery.min.js"></script>
<label>Digits Only:
<input type="text" />
</label>
<br>
<br>
EDIT :
In input type="number" we have to force it to always accept the updated val since many events does not work in it.So for that reason I have to update the existing value with the updated value after each event.
So I added
var v = $(this).val();
$(this).focus().val("").val(v);
So that each time the input is focused the value get updated with the existing value.
UPDATED FIDDLE FOR INPUT TYPE NUMBER
Updated snippet:
$(function() {
$('input').bind('keyup input', function(event) {
var v = $(this).val();
$(this).focus().val("").val(v);
var currValue = $(this).val();
if (currValue.search(/[^0-9]/) != -1) {
alert('Only numerical inputs please');
}
$(this).val(currValue.replace(/[^0-9]/, ''));
alert($(this).val());
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<label>Digits Only:
<input type="number" />
</label>
<br>
<br>
EDIT 2 : For special case + and -.I think its a bug I am not sure but check the below snippet.It works for all the cases.Hope it helps.
FINAL FIDDLE
$(function() {
$('input').bind('keyup', function(event) {
var v = $(this).val();
$(this).focus().val("").val(v);
var currValue = $(this).val();
$(this).val(currValue.replace(/[^0-9]/, ''));
alert(v);
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<label>Digits Only:
<input type="number" name="test" min=0 save="" oninput="validity.valid ? this.save = value : value = this.save;">
</label>

Hope it helps.For any other doubt feel free to ask.

Set format for decimal number

I am validating certain input by using RegEx in jQuery which is working as expected. I want to add an addition where it adds 0 prior to decimal point if user don't add it.
For example,
.50 to 0.50
-.50 to -0.50
How to do that?
Code:
$(document).ready(function() {
$('#btnval').click(function() {
var floatRegex = new RegExp(/^-?[0-9]+([\,|\.]{0,1}[0-9]{2}){0,1}$/);
var currentSetTextBoxValue = $('#txtval').val();
//alert(currentSetTextBoxValue);
var validateInput = floatRegex.test(currentSetTextBoxValue);
alert(validateInput);
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<input type="text" id="txtval" />
<input type="button" value="Get textbox Value" id="btnval" />

Change [0-9]+ to [0-9]*, so that it allows zero digits instead of requireing at least one.
$(document).ready(function() {
$('#btnval').click(function() {
var floatRegex = new RegExp(/^-?[0-9]*([\,|\.]{0,1}[0-9]{2}){0,1}$/);
var currentSetTextBoxValue = $('#txtval').val();
//alert(currentSetTextBoxValue);
var validateInput = floatRegex.test(currentSetTextBoxValue);
alert(validateInput);
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<input type="text" id="txtval" />
<input type="button" value="Get textbox Value" id="btnval" />

You can fix the value like this if you need to convert it later:
if(currentSetTextBoxValue.indexOf('.') === 0){
currentSetTextBoxValue = '0' + currentSetTextBoxValue;
}
if(currentSetTextBoxValue.indexOf('.') === 1 && currentSetTextBoxValue.indexOf('-') === 0){
currentSetTextBoxValue = '-0.' + currentSetTextBoxValue.split('.')[1];
}

You can replace the input using regex! This regex looks for . or -. at the beginning of the string and it will replace it by 0. or -0. depending on what it found, if it does not match the string will be the same.
$(document).ready(function() {
$('#btnval').click(function() {
var floatRegex = new RegExp(/^-?[0-9]+([\,|\.]{0,1}[0-9]{2}){0,1}$/);
var currentSetTextBoxValue = $('#txtval').val().replace(/^(\-)?\./, "$10.");
//alert(currentSetTextBoxValue);
var validateInput = floatRegex.test(currentSetTextBoxValue);
alert(validateInput);
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<input type="text" id="txtval" />
<input type="button" value="Get textbox Value" id="btnval" />

Display description in Username and Password field

I'm trying to create a similar login as in https://login.microsoftonline.com/. I want to display a description "someone#example.com" and "Password" in the fields.
I've tried to use the txReplaceFormPassword.js (http://snipplr.com/view/29555/) script to dynamically replace the fields but it is returning html text instead of the actual field.
<head>
<script src="#Url.Content("~/Scripts/txReplaceFormPassword.js")" type="text/javascript"></script>
<script type="text/javascript">
$(document).ready(function () {
$('.pwdfield').txReplaceFormPassword({
show_text: 'Password'
});
});
</script>
</head>
<div class="pwdfield">
#Html.PasswordFor(model => model.Password, new {#class = "k-textbox", style = "width:300px"})
#Html.ValidationMessageFor(model => model.Password)
</div>
I'm getting the following output in the browser:
Please let me know how can I get a description inside Password/Username field similar to the two links above.
Thanks.

I think this is what you want:
<input type="text" placeholder="someone#example.com" /><br />
<input type="password" placeholder="Password" />
As far as I know, you don't need to use js or jQuery for that. Just set the placeholder="" to the text you want to show in the fields.
Take a look on this link.
EDIT
Then use the following jQuery (tested on ie 7):
(function($){
var placeholderIsSupported = ('placeholder' in document.createElement('input'));
$.fn.emulatePlaceholder = function(){
if(!placeholderIsSupported){
this.each(function(index, element){
var handle = $(element);
var placeholder = handle.attr('placeholder');
if(handle.val() == ''){
handle.val(placeholder);
}
handle.blur(function(e){
var handle = $(this);
if(handle.val() == ''){
handle.val(placeholder);
}
});
handle.focus(function(e){
var handle = $(this);
if(handle.val() == placeholder){
handle.val('');
}
});
});
}
};
})(jQuery);
USAGE:
$('input').emulatePlaceholder();
