What I'm trying to accomplish is when a user has focus on a text box, the field set that's in will add a class "active_fieldset" so it gives a nice visual cue of where the user is in the form. Using the following javascript, it does affect the parent fieldset but it also affects all sibling fieldsets as well. Am I doing something wrong? Is there something fundamentally wrong with my HTML or javascript?
Example HTML:
<div id="content">
<form action="next_page" method="post">
<fieldset>
<legend>Foo</legend>
<p><label for="one">One</label> <input type="text" class="input_text" name="one" value="" id="one"></p>
</fieldset>
<fieldset>
<legend>Bar</legend>
<p><label for="two">Two:</label><input type="text" class="input_text" name="two" value="" id="two"></p>
</fieldset>
<p><input type="submit" value="Continue →"></p>
</form>
</div>
form.js:
$(document).ready(function(){
$('.input_text').focus(function(){
$(this).parents('fieldset').addClass("active_fieldset");
});
});
EDIT:
I've included my CSS:
fieldset
{
border-width: 10px 0 0 0;
border-style: solid;
border-color: #0D6EB8;
}
fieldset.active_fieldset
{
border-width: 10px 0 0 0;
border-style: solid;
border-color: #0D6EB8;
}
Try using the closest method. You'll probably need to pair this with some more code to make sure that the class has been removed from all the other field sets.
$('.input_text').focus( function() {
$('fieldset').removeClass('active_fieldset');
$(this).closest('fieldset').addClass('active_fieldset');
});
Quoting from the docs:
Closest works by first looking at the
current element to see if it matches
the specified expression, if so it
just returns the element itself. If it
doesn't match then it will continue to
traverse up the document, parent by
parent, until an element is found that
matches the specified expression. If
no matching element is found then none
will be returned.
I'd suggest:
$("input.input_text").focus(function() {
$("fieldset.active_fieldset").removeClass("active_fieldset");
$(this).parents("fieldset").addClass("active_fieldset");
}).blur(function() {
$("fieldset.active_fieldset").removeClass("active_fieldset");
});
Use parents() with parameter.
$("#test").parents('.something'); // will give you the parent that has a something class.
Perhaps it's the CSS code that has a bug. I think the suggestion to use JQuery.closest was correct.

Why is my code not working? i need to simulate click on radio button. Radio button has click event.
$(".form-group").click(function() {
alert("clicked")
$(this).closest(".hotelObj", function() {
$(this).trigger("click");
})
});
.form-group {
background-color: pink;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="form-group">
<label for="male" style="font-weight:800;">chose
<input type="radio" value="z6" class="hotelObj" name="hotelType">
<p>description</p>
</label>
</div>
Given the markup you've provided, javascript isn't necessary for this task, unless there's some other requirement you've left out.
Since the label contains all the area that you want the click handler to affect, it should just work as is (clicking anywhere in the pink box will cause the radio button to become selected).
.form-group {
background-color: pink;
}
<div class="form-group">
<label style="font-weight:800;">chose
<input type="radio" value="z6" class="hotelObj" name="hotelType">
<p>description</p>
</label>
</div>
Your code is not working because you are using .closest() jquery method which will look for element starting from itself and then up in DOM tree.
This way element with class.hotelObj is never found.
You need to use .find() method to find .hotelObj, because it's inside .form-group.
$(".form-group").click(function() {
$(this)
.find(".hotelObj")
.trigger("click");
});
Try onClickHandled property
<input type="checkbox" onclick="onClickHandler()" id="box" />
<script>
function onClickHandler(){
var chk=document.getElementById("box").value;
//use this value
}
</script>
I have a datepicker in a div with class pickergroup, I have 3 datepicker in my page, and this is why I use a group and different names
<div class="pickergroup">
<input type="text" name="day1" id="day1"/> /
<input type="text" name="month1" id="month1"/> /
<input type="text" name="year1" id="year1"/>
<input type="hidden" id="date1" name="date1"/>
<div id="datepicker1" name="calendar"></div>
</div>
In my jquery I want to detect when clicking the id wich starts with "datepicker", I guess something like:
$(document).on('click', '.pickergroup id^="datepicker"', function() {
$(".pickergroup").find('[id^="datepicker"]').datepicker({
//my datepicker code
});
});
but this is not correct.
how can I do it?
The problem is how you're selecting the element inside of the event handler.
$(".pickergroup").find('[id^="datepicker"]')
means "find all elements with the class of pickergroup. Find all of their children which have an ID starting with datepicker." Instead, you want to use this and fix your selector from
.pickergroup id^="datepicker"
to
.pickergroup [id^="datepicker"]
$(document).on('click', '.pickergroup [id^="datepicker"]', function() {
var $this = $(this); // The div that was clicked
console.log($this.text());
});
.pickergroup div {
float: left;
margin-right: 1em;
width: 200px;
height: 200px;
background: #0F0;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="pickergroup">
<div id="datepicker1">A</div>
</div>
<div class="pickergroup">
<div id="datepicker2">B</div>
</div>
<div class="pickergroup">
<div id="datepicker3">C</div>
</div>
<div class="pickergroup">
<div id="can-t-click-me">D</div>
</div>
First of all, the datepicker element needs to be an input. And remember, ID's are unique. If you using starts with selector, it is ok. But please dont get confusing with this.
Second, why need seperate fields? You could use one datepicker, decide the format you want to display and you could also parse the returned value from the datepicker in the format you need/want. Please have a look at the documentation.
I am trying to replace three check boxes within an html form with three different images. The idea being that the user can select the pictures by clicking on them rather than clicking on a check box. I've been putting togther some code but can't figure out how to make all the checkboxes selectable. At the moment only the first images works when it is clicked on. Can anyone help me? I'm a real novice with javascript I'm afraid. See fiddle here
The form
<form id="form1" action="" method="GET" name="form1">
<div class="col-md-3">
<img src="https://cdn2.iconfinder.com/data/icons/windows-8-metro-style/128/unchecked_checkbox.png" title="blr" id="blr"><input type="checkbox" id="imgCheck" name="pic1" value=9></div><div class="col-md-3">
<img src="https://cdn2.iconfinder.com/data/icons/windows-8-metro-style/128/unchecked_checkbox.png" title="blr" id="blr"><input type="checkbox" id="imgCheck" name="pic2" value=12></div><div class="col-md-3">
<img src="https://cdn2.iconfinder.com/data/icons/windows-8-metro-style/128/unchecked_checkbox.png" title="blr" id="blr"><input type="checkbox" id="imgCheck" name="pic3" value=7></div>
<input type="submit" name="submit" value="Add" />
</div>
</form>
The javascript
$('#blr').on('click', function(){
var $$ = $(this)
if( !$$.is('.checked')){
$$.addClass('checked');
$('#imgCheck').prop('checked', true);
} else {
$$.removeClass('checked');
$('#imgCheck').prop('checked', false);
}
})
Why use JavaScript at all? You can do this with CSS, the :checked attribute and a label element.
input[type=checkbox] {
display: none;
}
:checked+img {
border: 2px solid red;
}
<label>
<input type="checkbox" name="checkbox" value="value">
<img src="http://lorempixel.com/50/50/" alt="Check me">
</label>
This is happening because you're using the same ID more than one. IDs should be unique. Instead of using id="blr", try using class="blr". I updated the fiddle:
http://jsfiddle.net/0rznu4ks/1/
First, as Amar said, id should be unique. Use classes for multiple elements.
Also pay attention for semicolons and closing html tags.
To your question:
use the function .siblings() to get the relevant checkbox element.
$('.blr').on('click', function () {
var $$ = $(this);
if (!$$.is('.checked')) {
$$.addClass('checked');
$$.siblings('input.imgCheck').prop('checked', true);
} else {
$$.removeClass('checked');
$$.siblings('input.imgCheck').prop('checked', false);
}
});

Good luck!
My jQuery function looks like that
$('input[type="text"]').focus(function() {
$("label").css("border-bottom-color", "red");
});
$('input[type="text"]').blur(function() {
$("label").css("border-bottom-color", "#e6e6e6");
});
1) I have a bunch of text inputs in my form. What I want to do is to change bottom border color of focused text boxes label (there is one label for every text box. And I want to change only focused text boxes label's border color). But my functions changes all labels' border colors at once. How to fix that problem?
2) I have 2 forms. with id's form1 and form2. I want to do same things to second form but color will be another. How to modify this func?
My forms are looking like that
<form id="form1">
...
<label for="fname">First Name</label>
<input name="fname" placeholder="please enter your first name" type="text" />
...
</form>
<form id="form2">
...
<label for="job">Your Job</label>
...
<input name="job" placeholder="please enter your job" type="text" />
</form>
How about this fiddle?
http://jsfiddle.net/RvYca/3/
label tag's for attribute references to an input's id attribute, not its name.
I moved the styles to css too.
Use both CSS and JavaScript:
$('input:text, input:password, textarea').focus(
function(){
$(this).prev('label').addClass('focused');
}).blur(
function(){
$(this).prev('label').removeClass('focused');
});
And, in the CSS:
#form1 label.focused {
border-bottom: 1px solid red;
}
#form2 label.focused {
border-bottom: 1px solid green;
}
JS Fiddle demo.
For question 1, use $(this) as your selector:
$('input[type="text"]').focus(function() {
$(this).css("border-bottom-color", "red");
});
$('input[type="text"]').blur(function() {
$(this).css("border-bottom-color", "#e6e6e6");
});
For question 2, do you mean, after the user has selected both items, in either order? They can't both be in focus at the same time.
your selector is not specific enough for manipulating the css. You must be specific about which label you want to update. Something like this:
$('input[type="text"],textarea,input[type="password"]').focus(function() {
$("label[for='" + $(this).attr('id') + "']").css("border-bottom-color", "red");
});

The problem is that at least in Chrome(haven't tried other browsers yet) when the Chrome Password Manager saves your password and prefills the password for you when you pick the email. I use jquery to hide/show a div over the top of the password input field as a label, hiding that div when the user clicks into the password field (as can be seen in the above jsfiddle code). I need to know how to hide that div when Chrome prefills the password field...
I've haven't run into this myself, but it appears to be a common issue, based on a few quick Google Searches.
FireFox capture autocomplete input change event

One easy hack you could do is set up some code that runs every second or two via setInterval, and checks to see if the field has a value.
Something like this...
var code = $('#code');
var codeTip = $('#codetip');
var interval = setInterval(function(){
if (code.val()!=''){
codeTip.hide();
clearInterval(interval);
}
}, 1000);
I had the same issue. None of the solutions I found worked nicely enough. I ended up with this:
If it doesn't matter that your input fields have a background, I handled it just in CSS.
jsfiddle
I just gave the .inputPlaceholder { z-index: -1; } so that it aligned behind the input field and then set the input { background: transparent; } so you could see the div behind it.
Google's default -webkit-autofill style has a yellow background, so that just covers up your placeholder behind it all. No need to mess around with custom plugins/events/setIntervals.
