Onlick event not triggering which contains blur function

I have a form and on click on an input, I'm adding classes to that input's wrapped div.
To do this, I've made use of blur and executing my function on click. However, on some cases (very rarely) it will work (and add the class). But majority of the time, it doesn't perform the click action (because the console.log("click") doesn't appear).
My thinking is that maybe the browser is conflicting between the blur and click. I have also tried changing click to focus, but still the same results.
Demo:
$(function() {
var input_field = $("form .input-wrapper input");
$("form .input-wrapper").addClass("noData");
function checkInputHasValue() {
$(input_field).on('blur', function(e) {
var value = $(this).val();
if (value) {
$(this).parent().closest(".input-wrapper").removeClass("hasData noData").addClass("hasData");
} else {
$(this).parent().closest(".input-wrapper").removeClass("hasData noData").addClass("noData");
}
});
}
$(input_field).click(function() {
checkInputHasValue();
console.log("click");
});
});

i've done some modification in your code .
function checkInputHasValue(e) {
var value = $(e).val()
if (value) {
$(e).parent().closest(".input-wrapper").removeClass("hasData noData").addClass("hasData");
} else {
$(e).parent().closest(".input-wrapper").removeClass("hasData noData").addClass("noData");
}
}
$(document).on('blur',input_field, function(e) {
checkInputHasValue($(this));
});
$(document).on("click",input_field,function() {
checkInputHasValue($(this));
console.log("click");
});

In order to avoid conflits between events, you would separate the events and your value check. In your code, the blur event may occur multiple times.
The following code seems ok, as far as I can tell ^^
$(function() {
var input_field = $("form .input-wrapper input");
$("form .input-wrapper").addClass("noData");
function checkInputHasValue(el) {
let target = $(el).closest(".input-wrapper");
var value = $(el).val();
$(target).removeClass("hasData noData");
$(target).addClass(value.length == 0 ? "noData" : "hasData");
console.log("hasData ?", $(target).hasClass("hasData"));
}
$(input_field).on("click", function() {
console.log("click");
checkInputHasValue(this);
});
$(input_field).on("blur", function() {
checkInputHasValue(this);
});
});

Detect keydown event (mobile)

I'm currently working on a mobile app using cordova. I've ran into this problem where I have coded a function to detect whenever an user has typed into a text input field and pressing the enter key.
Here's the JavaScript snippet;
<script type="text/javascript">
$(function () {
$("#searchForm").on("input", function (e) {
e.preventDefault();
});
$("input").on("keydown", function (e) {
if (e.keyCode === 13) {
var keyField = document.createElement('input');
keyField.setAttribute('type', 'text');
document.body.appendChild(keyField);
setTimeout(function () {
keyField.focus();
setTimeout(function () {
keyField.setAttribute('style', 'display:none;');
}, 50);
}, 50);
}
});
});
</script>
the HTML part;
<form onsubmit="return false" id="searchForm">
<input type="text" id="fieldOne">
<input type="text" id="fieldTwo">
<input type="button" value="Search" id="search" onclick="executeSearches()"/>
</form>
This code works to achieve hiding the mobile keyboard, but when the hiding function executes the view is being moved because of the keyField -variable.
Is there any other ways I could achieve this function without the view being moved or can I somehow determine where the view is being moved to?

you are missing "#", check jquery selectors
$("#searchForm").on("input", function (e) {
e.preventDefault();
});

Disabled textbox change event

Short Explanation
I want to do something whenever disabled textbox value is changed
Detailed Explanation
I have a disabled text box which value is setting programitically I want to bind the change event of disabled textbox to fire some other function. This is what I tried but won't work.
$('#Rate').change(function() {
// alert("Change Event Called");
CalculateMedicine();
});
$('input[id$=Rate]').bind("change", function () {
CalculateMedicine();
});
This both thing don't work for me and the I don't like the idea to put a function CalculateMedicine() to all the place from which possibly Rate textbox is changing.So apart from this solution any help will be appreciated

assuming that your your input has disable class on on click or something else you check like this
if ($( "#input" ).hasClass( "disable" )) {
Your logics and codes here //
}
//Hope this would help

You can use triggerfor a change event:
<input type="text" disabled="disabled" name="fname" class="myTextBox" ><br>
<input type="button" name="submit" id="submit" value="Submit">
Javascript:
$(".myTextBox").change(function(){
console.log("yes i m working");
});
$("#submit").click("input", function() {
$(".myTextBox").val("New value").trigger("change");
});
Check Demo

It is possible if one redefines the value property of that input.
<html>
<head>
<script>
function Init(){
var tE = document.querySelector('input'); //Our input field.
//We redefine the value property for the input
tE._value = tE.value;
Object.defineProperty(tE, 'value', {
get: function(){return this._value},
set: function(v){
console.log(1, 'The value changed to ' + v)
this._value = v;
this.setAttribute('value', v) //We set the attribute for display and dom reasons
//Here we can trigger our code
}
})
}
function Test(){
//In one second we are going to change the value of the input
window.setTimeout(function(){
var tE = document.querySelector('input'); //Our input field.
tE.value = 'Changed!'
console.log(0, 'Changed the value for input to ' + tE.value)
}, 1000)
}
</script>
</head>
<body onload = 'Init(); Test();'>
<input type = 'text' disabled = 'true' value = 'Initial' />
</body>
</html>

The change event will not fire if you change the value programmatically
See https://stackoverflow.com/a/7878081/3052648
A not elegant possible solution:
function checkChanges(){
if(prevRate != $('#Rate').val()){
prevRate = $('#Rate').val();
alert('changed');
}
}
var prevRate;
$(document).ready(function(){
prevRate = $('#Rate').val();
setInterval(function(){
checkChanges();
} ,500);
});

You can fire change event by the following code from wherever you want to fire change event or any other event. The event will be fired either value changed or not. Just place the code after from where you are changing value programatically.
element.dispatchEvent(new Event('change'))
let input = document.querySelector("input");
input.addEventListener("change", () => alert("Change Event is Fired"));
input.value = "xyz";
input.dispatchEvent(new Event("change"));
<input type="text" disabled value="abc">

replacing a smallcaps to allcaps text

I'm having trouble to convert all lower case to upper case in a text box:
<body>
<input type="text" id="input_1" class="allcaps"/>
<input type="text" id="input_2" class="allcaps"/>
</body>
$(document).ready(function () {
//trigger ng event
$('.alcaps').live("keyup", function () {
var fin = $('.alcaps').val();
$('.alcaps').val(fin.toUpperCase());
});
});
The first input box transforms its contents to capitals, but the text I put in the first box is also copied to the second input...

When using the class as selector you're selecting all input boxes with that class and setting the value to the same as the first one. Use the this keyword to target only the current textbox :
$(document).ready(function() {
$(document).on('keyup', '.alcaps', function() {
var fin = this.value;
this.value = fin.toUpperCase();
});
});​
FIDDLE

You can use this which refers to your current input, also note than live is deprecated, you can use on instead:
$(document).on("keyup", ".alcaps", function () {
this.value = this.value.toUpperCase()
});

User this inside the handler:
$('.alcaps').live("keyup", function () {
var fin = $(this).val();
$(this).val(fin.toUpperCase());
});

Need to enable/disable a button on click of checkbox

I am trying to disable a order button when the page loads and enable it when one checks the Terms and condition checkbox. I have it working where the order button is disabled when the page loads but on the click of checkbox the button doesnt get enabled. Here is my code. Can anyone help me identify the problem
<input type="checkbox" id="checkbox1" name="checkbox1" class="required" />Please read the Terms and Conditions
Jquery Code
var j$ = jQuery.noConflict();
j$(document).ready(function(){
alert("Hi");
if(j$('input[name="checkbox1"]').not(":checked"))
{
j$('input[name="Order"]').attr('disabled', 'disabled');
}
else
{
j$('input[name="Order"]').removeAttr('disabled');
}
j$('#checkbox1').change(function(){
if(j$('input[name="checkbox1"]').is(":checked")
{
j$('input[name="Order"]').attr('disabled', 'disabled');
}
else
{
j$('input[name="Order"]').removeAttr('disabled');
}
}
});
Thanks

The code you provided had some missing ( and {, here is an updated version with some changes to handle the checkbox state properly:
var j$ = jQuery.noConflict();
j$(document).ready(function() {
var checkbox1 = j$('#checkbox1');
var order = j$('input[name="Order"]');
var verifyChecked = function() {
if (checkbox1.is(":checked") === false) {
order.attr('disabled', 'disabled');
} else {
order.removeAttr('disabled');
}
};
verifyChecked();
checkbox1.change(verifyChecked);
});
Here is a jsfiddle with it working:
http://jsfiddle.net/7uRf6/4/

You have missed a closing parenthesis
if(j$('input[name="checkbox1"]').is(":checked")
should be
if(j$('input[name="checkbox1"]').is(":checked"))
Also you can use an id selector instead of this attribue selector.
And if you want to enable the button when the checkbox is checked you have to
if(!j$('input[name="checkbox1"]').is(":checked"))

in your change event,
if(j$('input[name="checkbox1"]').is(":checked")
it should be
if(j$('input[name="checkbox1"]').not(":checked")
I suggest you to create a function to check it.
var j$ = jQuery.noConflict();
j$(document).ready(function(){
ToggleButton();
j$('#checkbox1').change(ToggleButton);
});
function ToggleButton()
{
if(j$('input[name="checkbox1"]').not(":checked"))
{
j$('input[name="Order"]').attr('disabled', 'disabled');
}
else
{
j$('input[name="Order"]').removeAttr('disabled');
}
}

<script src="jquery.js"></script>
<script>
$(document).ready(function (){
$('#ch').click(
function (){
if($(this).is(':checked')){
$('#bt').attr('disabled','disabled');
}
else {
// remove
$('#bt').removeAttr('disabled');
}
}
)
})
</script>
<input type="button" value="button" id="bt"/>
<input type="checkbox" id="ch"/>
