jquery - show textbox when checkbox checked - javascript

I have this form
<form action="">
<div id="opwp_woo_tickets">
<input type="checkbox" class="maxtickets_enable_cb" name="opwp_wootickets[tickets][0][enable]">
<div class="max_tickets">
<input type="text" name="opwp_wootickets[tickets][0][maxtickets]">
</div>
<input type="checkbox" class="maxtickets_enable_cb" name="opwp_wootickets[tickets][1][enable]">
<div class="max_tickets">
<input type="text" name="opwp_wootickets[tickets][1][maxtickets]">
</div>
<input type="checkbox" class="maxtickets_enable_cb" name="opwp_wootickets[tickets][2][enable]">
<div class="max_tickets">
<input type="text" name="opwp_wootickets[tickets][2][maxtickets]">
</div>
</div>
</form>
As of now, I'm using this jquery code to show textbox when checkbox checked.
jQuery(document).ready(function($) {
$('input.maxtickets_enable_cb').change(function(){
if ($(this).is(':checked')) $('div.max_tickets').show();
else $('div.max_tickets').hide();
}).change();
});
It works fine, but it shows all textboxes when checked.
Can someone help me to fix it?
Here is the demo of my problem.
http://codepen.io/mistergiri/pen/spBhD

As your dividers are placed next to your checkboxes, you simply need to use jQuery's next() method to select the correct elements:
if ($(this).is(':checked'))
$(this).next('div.max_tickets').show();
else
$(this).next('div.max_tickets').hide();
Updated Codepen demo.
From the documentation (linked above), the next() method selects:
...the immediately following sibling of each element in the set of matched elements. If a selector is provided, it retrieves the next sibling only if it matches that selector.
Here we're selecting the next div.max_tickets element. However in your case just using next() with no parameters would suffice.

Assuming markup will stay in same order can use next()
jQuery(document).ready(function($) {
$('input.maxtickets_enable_cb').change(function(){
$(this).next()[ this.checked ? 'show' : 'hide']();
}).change();
});

Change:
if ($(this).is(':checked')) $('div.max_tickets').show();
To:
if ($(this).is(':checked')) $(this).next('div.max_tickets').show();
jsFiddle example here

Maybe try selecting the next element only?
change:
if ($(this).is(':checked')) $('div.max_tickets').show();
to:
if ($(this).is(':checked')) $(this).next('div.max_tickets').show();

Put a div across your checkbox and text box
<form action="">
<div id="opwp_woo_tickets">
<div>
<input type="checkbox" class="maxtickets_enable_cb" name="opwp_wootickets[tickets][0][enable]">
<div class="max_tickets">
<input type="text" name="opwp_wootickets[tickets][0][maxtickets]">
</div>
</div>
<div>
<input type="checkbox" class="maxtickets_enable_cb" name="opwp_wootickets[tickets][1][enable]">
<div class="max_tickets">
<input type="text" name="opwp_wootickets[tickets][1][maxtickets]">
</div>
</div>
<div>
<input type="checkbox" class="maxtickets_enable_cb" name="opwp_wootickets[tickets][2][enable]">
<div class="max_tickets">
<input type="text" name="opwp_wootickets[tickets][2][maxtickets]">
</div>
</div>
</div>
</form>
and replace your jquery code with this one below,
jQuery(document).ready(function($) {
$('input.maxtickets_enable_cb').change(function(){
if ($(this).is(':checked')) $(this).parent().children('div.max_tickets').show();
else $(this).parent().children('div.max_tickets').hide();
}).change();
});
I have tested it and it works.

While you may need a JavaScript solution for other reasons, it's worth noting that this can be achieved with pure CSS:
input + div.max_tickets {
display: none;
}
input:checked + div.max_tickets {
display: block;
}
JS Fiddle demo.
Or, with jQuery, the simplest approach seems to be:
// binds the change event-handler to all inputs of type="checkbox"
$('input[type="checkbox"]').change(function(){
/* finds the next element with the class 'max_tickets',
shows the div if the checkbox is checked,
hides it if the checkbox is not checked:
*/
$(this).next('.max_tickets').toggle(this.checked);
// triggers the change-event on page-load, to show/hide as appropriate:
}).change();
JS Fiddle demo.
Reference:
CSS:
:checked pseudo-class.
jQuery:
change().
next().
toggle().

protected void EnableTextBox()
{
int count = int.Parse(GridView1.Rows.Count.ToString());
for (int i = 0; i < count; i++)
{
CheckBox cb = (CheckBox)GridView1.Rows[i].Cells[0].FindControl("CheckBox1");
CheckBox cb1 = (CheckBox)GridView1.Rows[i].Cells[0].FindControl("CheckBox2");
CheckBox cb2 = (CheckBox)GridView1.Rows[i].Cells[0].FindControl("CheckBox3");
TextBox tb = (TextBox)GridView1.Rows[i].Cells[4].FindControl("txtration");
TextBox tb1 = (TextBox)GridView1.Rows[i].Cells[5].FindControl("txtjob");
TextBox tb2 = (TextBox)GridView1.Rows[i].Cells[6].FindControl("txtaadhar");
if (cb.Checked == true)
{
tb.Visible = true;
}
else
{
tb.Visible = false;
}
if (cb1.Checked == true)
{
tb1.Visible = true;
}
else
{
tb1.Visible = false;
}
if (cb2.Checked == true)
{
tb2.Visible = true;
}
else
{
tb2.Visible = false;
}
}
}
protected void CheckBox1_CheckedChanged(object sender, EventArgs e)
{
EnableTextBox();

Checkbox Hidden Div Unchecked

I have a checkbox hidden div with text field. If checkbox is checked this text field will showed, but if checkbox unchecked text field not show. This Code :
<script type="text/javascript">
$(function () {
$("input[name='checkbox1']").click(function () {
if ($("#checkyes1").is(":checked")) {
$("#dvcheckbox1").show('lainnya');
} else {
$("#dvcheckbox1").hide('lainnya');
}
});
});
</script>
<div style="margin-left: 29%; margin-top: -2%;">
<label for="checkyes1">
<input type="checkbox" id="checkyes1" name="checkbox1" value="lainnya" />
Lainnya
</label>
<div id="dvcheckbox1" style="display: none;">
<?php echo $form->textField($model,'lainnya'); ?>
</div>
</div>
But, How this checkbox is checked if there something value on textfield? and text field shown. Because in form Update, value was show but checkbox is checked. I want checkbox is checked
For example Like this:
Click to show example
Instead use with change event with .toggle(boolean) method:
// on page load check of the div contains any text
$("#dvcheckbox1").toggle(function(){
var $v = $(this).find('input').val();
$("input[name='checkbox1']").prop('checked', $v.trim().length !== 0)
return $v.trim().length !== 0;
});
$("input[name='checkbox1']").change(function () {
$("#dvcheckbox1").toggle(this.checked);
});
There are a few things here:
1 - Better if you use document ready, because it waits until all the elements are loaded.
2 - You should hide the element$("#dvcheckbox1").hide('lainnya') when the page is loaded.
3 - A listener in the input:text is a good idea. It enables the checkbox if the textbox is empty.
Please, have a look at the next piece of code:
<div>
<label for="checkyes1">
<input type="checkbox" id="checkyes1" name="checkbox1" value="lainnya" />
Lainnya
</label>
<div id="dvcheckbox1">
<label for="myValuye"/>
<input type="text" id="myValue" name="myValue" value=""/>
</div>
</div>
<script>
$(document).ready(function() {
$("input[name='checkbox1']").click(function () {
// Always use some logs to check what line are you reaching.
console.log("Clicked checkbox!!!");
if ($("#checkyes1").is(":checked")) {
$("#dvcheckbox1").show('lainnya');
} else {
console.log("Value: " + $("#myValue").val());
$("#dvcheckbox1").hide("lainnya");
}
});
$("#myValue").bind("change paste keyup", function() {
if ($(this).val() == "") {
$("#checkyes1").removeAttr("disabled");
} else {
$("#checkyes1").attr("disabled", true);
}
});
// First of all we hide the #dvcheckbox1
$("#dvcheckbox1").hide('lainnya');
})

Javascript - check/uncheck checkbox after summing different inputs

I have a ‘parent’ <div>, and ‘child’ divs which are shown after clicking parent <div>.
All divs have <checkboxes> and <input> to put quantity.
Parent <checkbox> checks when at least one child <checkbox> is checked.
When child <checkbox> is checked/unchecked the quantity in <input> is automatically changed into ‘1’ or ‘’.
Parent quantity <input> is disabled and it is supposed to show the sum of all children quantities.
I have two problems.
First, the summing script works fine when you enter the quantity yourself, however when the quantity appears/disappears itself (after checking/unchecking the child <checkbox>) the summing script does not react on such change.
Secondly I wasn’t able to uncheck the parent <checkbox> when all child checkboxes are unchecked.
However I’m assuming if the summing script will start working properly I will be able to bind the parent <checkbox> with the sum (if (sum> 0){ $('#checkbox0').prop('checked', true);}else{$('#checkbox0').prop('checked', false);}

JSFiddle: https://jsfiddle.net/mamzj4tw/6/
This is an updated version of your version
https://jsfiddle.net/mamzj4tw/13/
It uses each() to better (and clean) add actions to inputs.
You can create your custom events like do-sum and fire when you want.
In this case I defined that the sum is executed when
$(document).trigger('do-sum');
fires do-sum event.
and I've set a listener that executes your routine:
$(document).on('do-sum', function(){
var sum = 0;
$('.quantity_class_child.active').each(function(){
sum += +$(this).val();
});
$('#quantity_parent_1').val(sum);
var parentChecked = false;
$('#hidden1 input[type="checkbox"]').each(function(i, e){
if($(e).is(':checked')) {
parentChecked = true;
}
});
$('#checkbox0').prop('checked', parentChecked);
});
I also use class active to set valid inputs (and quick sum them).
PS you don't need event.preventDefault(); after document ready event.
Ok, Here are the things that you can do to achieve,
First, the summing script works fine when you enter the quantity yourself, however when the quantity appears/disappears itself (after checking/unchecking the child ) the summing script does not react on such change.
The thing is change event will not be triggered if you are setting/changing the value from the javascript. For this you can manually call the change event to trigger the effect. Or, Create a separate function for summation calculation and call it on uncheck event of the checkbox.
eg.
Either
$('#checkbox1').click(function() {
if (this.checked) {
$('#checkbox0').prop('checked', this.checked);
$('#quantity_child_1').val('1')
} else {
$('#quantity_child_1').val('')
$(".quantity_class_child").trigger("change");
//$('#checkbox0').prop('checked', false);
}
});
OR
$('#checkbox1').click(function() {
if (this.checked) {
$('#checkbox0').prop('checked', this.checked);
$('#quantity_child_1').val('1')
} else {
$('#quantity_child_1').val('');
summation();
}
});
function summation(){
var sum = 0;
$('.quantity_class_child').each(function() {
sum += +$(this).val();
});
$('#quantity_parent_1').val(sum);
}
Now for the second part,
Secondly I wasn’t able to uncheck the parent when all child checkboxes are unchecked.
Just check the length of the checked input box during the summation process and uncheck it if the the length is zero.
Hope this help you cause.
Your code was a bit to complicated, so i have rewritten what you tried to archive ( without the css part). fiddle here
three little html div's
<div class="parent" id="parent">
<span class="input">
<input type="checkbox" name="parent" value="">
<label for parent>parent - click to open</label>
<input type="text" name="sum">
</span>
</div>
<div class="child" id="child1">
<span class="input">
<input type="checkbox" class="inputCheckbox" name="child1" value="child1">
<input type="text" class="inputSum" name="sum1">
</span>
</div>
<div class="child" id="child2">
<span class="input">
<input type="checkbox" class="inputCheckbox" name="child2" value="child2">
<input type="text" class="inputSum" name="sum2">
</span>
</div>
and a bit of jquery
$('.child').hide();
// check if parent checkbox is checked
$('input[name="parent"]').click ( function () {
if ( $(this).is(':checked') ) $('.child').show(); else $('.child').hide();
})
// check if childcheckbox is checked , if true trigger keyup and sum
$('.inputCheckbox').on ( 'change', function () {
if ( $(this).is(':checked') ) $(this).next().val('1').keyup();
// if not , trigger parent
if ( ! $('.inputCheckbox').is(':checked') ) $('input[name="parent"]').click ();
})
// check if value is entered and sum it on keyup
$('.inputSum').on('keyup', function () {
var sum = 0;
$('.inputSum').each ( function () { sum += ( $(this).val() - 0) })
$('input[name="sum"]').val(sum)
})
HTH
You can add new elements https://jsfiddle.net/mamzj4tw/34/
$(document).ready( function() {
$('.drop-down #checkbox').on('change',function(){
$(this).closest('.divCell').find('#quantity_child')
.val(this.checked ? 1:'').trigger('keyup');
});
$(document).on('keyup click', '.quantity_class_child', function(){
$(this).closest('.divCell').find('#checkbox').prop("checked",+$(this).val());
var sum = 0;
$('.quantity_class_child').each(function(){sum += +$(this).val()});
$('#quantity_parent_1').val(sum ||'');
$('#checkbox0').prop("checked", sum);
});
$('#click1').click(function() { $('#hidden1').toggle(500); });
});

Show/Hide Form Fields on checkbox checked/unchecked

I'm using JavaScript to show/hide additional fields in my form depending on whether the relevant checkbox is clicked. The fields are hidden and they do show when the checkbox is ticked, but DO NOT hide when it is un-ticked. However, the fields do hide when I tick the checkbox again.
I have the checkbox with id='cb_post' and an onclick command to fetch showDiv() from my external javascript file. I also have the hidden field with id='hiddenDiv'.
My javascript script is simple:
function showDiv() {
if (document.getElementById('hiddenDiv').style.display == 'block') {
(document.getElementById('hiddenDiv').style.display = 'none');
} else {
document.getElementById('hiddenDiv').style.display = 'block';
}
}
Can anyone advise on how to hide the fields when the checkbox is unticked?
You should think about using jQuery
$("#hiddenDiv").hide();
$("#hiddenDiv").show();
and something nicer
$("#hiddenDiv").fadeOut();
$("#hiddenDiv").fadeIn();
I think using jQuery toggle would fit better for your problem:
<input type="checkbox" id="cb_post">
<div id = "hiddenDiv">
<li>Toggle me</li>
</div>
$("#cb_post").on('click', function(){
$("#hiddenDiv").toggle();
});
Maybe using the event onchange instead of onclick would be more elegant.
https://jsfiddle.net/qqL0sxxs/
Here is working code :
var chebx = document.getElementsByClassName('toggleField');
for (var i = 0; i < chebx.length; i++) {
chebx[i].addEventListener('click', toggleField, false);
}
function toggleField() {
var field = document.getElementById(this.dataset.target);
if (field) {
switch (this.checked) {
case true:
if (field.classList.contains('hide')) {
field.classList.remove('hide');
} else {
field.classList.add('hide');
}
break;
default:
break;
}
}
}
.hide {
display: none;
}
<lable for='toggleField'>Toggle Field</lable>
<input type="checkbox" data-target='field1' class='toggleField'>
<input type='text' class='hide' id='field1' />
<hr>
<lable for='toggleField'>Toggle Field</lable>
<input type="checkbox" data-target='field2' class='toggleField'>
<input type='text' class='hide' id='field2' />

jQuery - Checking Check Box Values (Chaining jQuery functions Vs If Statment)

I have multiple check boxes and wanting to get an overall value for them all.
For example if one is checked then value is true/selected.
If none are checked then false/unchecked.
My HTML is:
<input id="one" type="checkbox">
<input id="two" type="checkbox">
<input id="three" type="checkbox">
<input id="four" type="checkbox">
<button onclick="check();">Is checked (jQuery Chained)</button>
<button onclick="check2();">Is checked(Big If Statement)</button>
My JavaScript/jQuery is:
function check() {
var booleee = $('#one,#two,#three,#four').attr('checked');
alert("Checked: " + booleee);
}
function check2() {
if ($('#one').attr('checked') || $('#two').attr('checked') || $('#three').attr('checked') || $('#four').attr('checked')) {
alert("Checked: true");
}
alert("Checked: false");
}
Js Fiddle: Click Here
Please note, I have solved this problem. This question is more to help me understand why my checked2() function works and my check() doesnt.
var booleee = $('#one,#two,#three,#four').attr('checked'); checks only whether the first (in this case #one) checkbox is checked.
From the doc for attr
Get the value of an attribute for the first element in the set of
matched elements.
it should be
var booleee = $('#one,#two,#three,#four').filter(':checked').length > 0;
Also in new versions(>1.6) you need to use the property 'checked' (.prop('checked')) instead of attr in the alternative you have a :checked filter so .is(':checked').
Because it's not checking all the elements in the selector.
to make it work
function check() {
var booleee =$("input:checkbox:checked").length > 0;
alert("Checked: " + booleee);
}
To more specific selection add form id in selector
DEMO
A better approach: http://jsfiddle.net/arvind07/ZP78F/
function check() {
var checks = $('input:checkbox');
var checked = 0;
checks.each(function() {
if ($(this).is(":checked")) {
checked = 1;
return false;
}
});
if (checked) {
alert("Checked");
} else {
alert("Not checked");
}
}
in html set checked property
<input id="one" type="checkbox" checked="checked">
<input id="two" type="checkbox" checked="checked">
<input id="three" type="checkbox" checked="checked">
<input id="four" type="checkbox" checked="checked">
you not defined checked so it show undefined because it cant read this attribute and when you call second function then only false come in alert because their checkbox checked attribute not find
see demo
var checked = $(':checkbox:checked').length > 0;

Check to see if none of the checkboxes was checked in jquery

I have two checkboxes and one of the checkboxes must be checked. I can see that it's right, no syntax errors. What should be made to my code to check if none of the checkboxes were checked?
HTML :
<input type="checkbox" value="aa" class="first" name="a"> Yes<br/>
<input type="checkbox" value="bb" class="second" name="b"> No <br/>
<button type="submit">Go!</button>
<p class="error"></p>
JavaScript:
$('button').on('click',function(){
if( $(".first:not(:checked)") && $(".second:not(:checked)") ){
$('.error').text('You must select atleast one!');
}else
$('.error').hide();
});
Example : http://jsfiddle.net/ptbTq/
Check this fiddle: http://jsfiddle.net/692Dx/
Checking code:
if($('input[type="checkbox"]:checked').length == 0) {
alert('none checked');
}
You are using selectors which do not return boolean values which is what you need when writing an if condition. Here's what you could do:
$('button').on('click',function() {
if(!$(".first").is(":checked") && !$(".second").is(":checked")) {
$('.error').text('You must select atleast one!').show();
} else {
$('.error').hide();
}
});
or if you prefer and think it could be more readable you could invert the condiciton:
$('button').on('click',function() {
if($(".first").is(":checked") || $(".second").is(":checked")) {
$('.error').hide();
} else {
$('.error').text('You must select atleast one!').show();
}
});
Also notice that you need to .show() the error message in the first case as you are hiding it in the second.
And here's a live demo.
Short:
$("input[type=checkbox]").is(":checked")
returns true if:
one of your checkboxes - from the selector ("input[type=checkbox]") - is checked.
else return false
and in your case:
$(".first, .second").is(":checked")
Do something at least one of your checkboxes is checked
Put the same class on both checkboxes and you can do something like
if ($(':checkbox.the_class:checked').length > 0) {
// at least one checkbox is checked
// ...
}
The best would be to put your checkboxes inside a div with an unique ID so you can verify all the checkboxes in there, so your code will work in all cases. Even when adding new checkboxes to the div later on.
<div id="cb">
<input type="checkbox" value="aa" class="first" name="a" /> Yes<br/>
<input type="checkbox" value="bb" class="second" name="b" /> No <br/>
<button type="submit">Go!</button>
<p class="error"></p>
</div>
Your JQuery:
$('button').click(function() {
var checked_one = $('div#cb input[type="checkbox"]').is(':checked');
if (!checked_one )
$('.error').text('You must select atleast one!');
else
$('.error').hide();
});
Live demo can be seen here: http://jsfiddle.net/ptbTq/15/
