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);
});
});

<form>
<div class="input-wrapper">
<input>
</div>
</form>

Jquery click event on button without class or id

I have this button that I can't change, nor can I edit toCashier():
<input type="button" value="Till kassan" onclick="toCashier()">
And I want to track if it's clicked and execute some javascript.
$(document).ready ( function () {
$('button[value="Till kassan"]').on('click', function(){
alert("Night button clicked");
});
});
I tried that but it doesn't seem to work. I tried various things but can't get it to work.

You have mismatched input and button, try the following :
$(document).ready ( function () {
$('input[value="Till kassan"]').on('click', function(){
alert("Night button clicked");
});
});
Or
$(document).ready ( function () {
$('input[type="button"][value="Till kassan"]').on('click', function(){
alert("Night button clicked");
});
});

button !== input
You need to use the correct selector.
$('input[value="Till kassan"]')

If you make the click with function, toCashier() function need to create :
function toCashier(){
alert("Night button clicked");
}

jquery input field focus out except a div

I'm making ajax suggestion of search in which,
a suggestion box will be displayed
<div id="searchbox">
<input type="text" name="search" class="searchinput"/>
</div>
<div id="sugbox">
......
<a href="product.php?id=2" >Item 1</a>
.....
</div>
and Javascript
$('#searchbox .searchinput').focus(
function () {
$('#searchbox #sugbox').show();
});
$('#searchbox .searchinput').focusout(
function () {
$('#searchbox #sugbox').hide();
});
The suggestion box will open if the search textbox #searchbox .searchinput is focus and hide if focusout.
Problem : whenever i'm clicking the link on suggestion box, the suggestion box hides (because of input focusout event).
How can i check if the target div is the suggestion box so don't hide the box
ex ..
$('#searchbox .searchinput').focusout(
function () {
if(target div is not sugbox)
$('#searchbox #sugbox').hide();
});

try to assign a class to sugbox at hover class
$(".searchinput").focus(function(){
$("#sugbox").show();
});
$(".searchinput").focusout(function(){
if(!$("#sugbox").hasClass("hovered"))
$("#sugbox").hide();
});
$("#sugbox").hover(function(){
$(this).addClass("hovered");
},function(){
$(this).removeClass("hovered");
});
here is example at jsfiddle : http://jsfiddle.net/kyawlay/9wg49L2b/5

add a mousedown handler (triggerd before focusout/blur I think) on the box also, set a flag to true when clicked, then check this flag before hidding
var boxClicked = false;
$('#mainsearch .searchinput').mousedown(// listen click handler
function () { boxClicked = true;});
$(document).mousedown(// reset boxclicked
function () { boxClicked = false;});
$('#searchbox .searchinput').focus(
function () {
$('#searchbox #sugbox').show();
});
$('#mainsearch .searchinput').focusout(
function () {
if(!boxClicked) $('#mainsearch #sugbox').hide();// add condition
});

You are using wrong selector. Check this demo. http://jsfiddle.net/m711LLwr/
$('#searchbox #sugbox').show();
Should be
$('#mainsearch #sugbox').show();

Try this, What it does is when searchinput loses focus then if sugbox has no class 'NoHide', then hide it.
On body on click event, the NoHide class is assigned to sugbox if click target is not searchinput and not sugbox and not sugbox anchor.
If event target is not in above 3 mentioned selectors then remove class NoHide. I have a fiddle but I want you to try in your page as fiddle will confuse you( as it has iframe and body area of fiddle is limited).
$('#searchbox .searchinput').focus(
function () {
$('#sugbox').show();
});
$('#searchbox .searchinput').focusout(
function (event) {
if(!$('#sugbox').hasClass('NoHide'))
$('#sugbox').hide();
});
$('body').on('click',
function (event) {
if(!$(event.target).is(".searchinput") && !$(event.target).is("#sugbox a") && !$(event.target).is("#sugbox")){
$("#sugbox").hide().removeClass('NoHide');
}else
{
$("#sugbox").show().addClass('NoHide');
}
});

Detect change in an input field when selecting value from a box

I want to detect a change in the input field when i select a value from the box like in the picture below.
html:
<input type="text" class="AgeChangeInput" id="range"/>
js:(not working)
<script>
$(document).ready(function()
{
alert("Hello");
$("#range").bind('input', function()
{
alert("done");
});
});
</script>
I also tried live on functions but they didn;t work too.

Your date selection box should fire a change event, then you only need to capture it:
$(function () {
$('#range').change(function () {
...
});
});
If the selection box doesn't fire the event, you'll need to trick the dom. Something like:
$(document).ready(function () {
// Asuming your selection box opens on input click
$('#range').click(function () {
$('.special-box-class').click(fireRangeEvent);
});
// Now the firing function
function fireRangeEvent() {
...
}
});
Hope it works

Try to use this code
changeDate - This event is fired when the date is changed.
$('#range').datepicker().on('changeDate', function(ev) {
//example of condition
if (ev.date.valueOf() > checkout.date.valueOf()) {
//make action here
alert('Here');
}
});

Select all the text in an input, focusin

I want to have all the text selected when I give the focus to an element.
I used
$('.class-focusin').focusin(function(e) {
$(this).select();
});
But it's not the perfect behavior I want. When i click between two characters, the input value is not seleted, there is a cursor in the middle.
I want the behavior of the url bar in chrome browser: you click and the cursor is replaced by the value selection
Feel free to test my problem in this fiddle:
http://jsfiddle.net/XS6s2/8/
I want the text to be able to receive the cursor once selected.
The answer selected, below is definitely what I wanted, Thanks

You could have a variable to see if the text has been selected or not:
http://jsfiddle.net/jonigiuro/XS6s2/21/
var has_focus = false;
$('.class-focusin').click(function(e) {
if(!has_focus) {
$(this).select();
has_focus = true;
}
});
$('.class-focusin').blur(function(e) {
has_focus = false;
});

I guess you have to wait for the browser to give focus to the element, then do your selection:
$('.class-focusin').focus(function(e) {
var $elem = $(this);
setTimeout(function() {
$elem.select();
}, 1);
});
Yuck. Or simply bind to the click event instead:
$('.class-focusin').click(function(e) {
$(this).select();
});

Try using click instead of focusin.
$('.class-focusin').click(function(e) {
$(this).select();
});
Demo
Bye!

Working Demo http://jsfiddle.net/cse_tushar/XS6s2/22/
$(document).ready(function () {
$('.class-focusin').click(function (e) {
$(this).select();
});
});

It's a direct duplicate of Select all the text in an input, focusin, here's a nice answer from it
$(".class-focusin").on("focus",function(e){
$(this).select();
});
$(".class-focusin").on("mouseup",function(e){
e.preventDefault();
});
