I have different checkboxes generated dynamically.
Each checkboxes are contained within a div.
I would like to do the following action with jquery:
If a checkbox has an id="aucune", then remove its container (the div containing the checkbox with the id="aucune") from the html page.
I tried the following code:
// wait for DOM to be ready
$(document).ready(function() {
var empty = $("input:checkbox[id=aucune]");
if (empty == true) {
$(this).parent().remove();
}
});
Here is a the very simplified html:
<div class="wrapper-checkbox">
<input type="checkbox" class="outsider" id="xxx" name="xxx" date-name="xxx">
<label for="xxx">xxx</label>
</div>
<div class="wrapper-checkbox">
<input type="checkbox" class="outsider" id="aucune" name="aucune" date-name="aucune">
<label for="aucune">aucune</label>
</div>
Here is my codepen:
I am quite new to code, I apologize for my silly simple question.
You can directly select the id with jQuery and remove the parent.
$('#acune').parent().remove();
Or if you know the class of the parent element
$('#acune').parent('.wrapper-checkbox').remove();
You are wrongly referencing this. It should be this way:
Replace this with empty.
Replace the boolean check with count.
Note: You can also use $("#aucune") instead of the selector $("input:checkbox[id=aucune]").
// wait for DOM to be ready
$(document).ready(function() {
// Or here you can also use $("#aucune").
var empty = $("input:checkbox[id=aucune]");
// Check if it is found.
if (empty.length > 0) {
// Remove the parent.
empty.parent().remove();
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="wrapper-checkbox">
<input type="checkbox" class="outsider" id="xxx" name="xxx" date-name="xxx">
<label for="xxx">xxx</label>
</div>
<div class="wrapper-checkbox">
<input type="checkbox" class="outsider" id="aucune" name="aucune" date-name="aucune">
<label for="aucune">aucune</label>
</div>
Boom! And the checkbox is gone! :)
You can directly use the aucune id selector in your JQuery and then get the closest div with class wrapper-checkbox to remove it:
$(document).ready(function() {
var empty = $("#aucune");
if (empty.length !== 0){
$(empty).closest('.wrapper-checkbox').remove();
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="wrapper-checkbox">
<input type="checkbox" class="outsider" id="xxx" name="xxx" date-name="xxx">
<label for="xxx">xxx</label>
</div>
<div class="wrapper-checkbox">
<input type="checkbox" class="outsider" id="aucune" name="aucune" date-name="aucune">
<label for="aucune">aucune</label>
</div>
Try to do this..
$(document).ready(function() {
var checkbox = $("input:checkbox[id=aucune]");
if (checkbox.length > 0) {
checkbox.parent().remove();
}
});

I'd like to get the source code of a div, so example if a div contains some tags I'd like to get them as they are in html format and update it on a textfield.
JsFiddle : https://jsfiddle.net/Lindow/g1sp1ms3/2/
HTML :
<form>
<label class="tp_box_1">
<input type="radio" name="selected_layout" class="selected_layout" value="layout_1">
<div class="box_1">
<h3>box_one</h3>
<p>1</p>
</div>
</label>
<br><hr><br>
<label class="tp_box_2">
<input type="radio" name="selected_layout" class="selected_layout" value="layout_2">
<div class="box_2">
<h3>box_two</h3>
<p>2</p>
</div>
</label>
<textarea id="mytextarea"></textarea>
<input id="submit_form" type="button" value="Send">
</form>
JavaScript :
$('input[type="radio"][name="selected_layout"]').change(function() {
if(this.checked) {
// get the specific div children of $this
var selected_layout = $(this).find('.selected_layout');
// get source code of what's inside the selected_layout
/* example :
<h3>box_two</h3>
<p>2</p>
and put it in someVariable.
*/
// and put in into textarea (all this need to happens when a radio is changed with the source code of the checked div)
var someVariable = ...
$('textarea').val(someVariable);
}
});
How can I achieve this ? How can I get the source code inside a specific div ?
First, you don't want selected_layout to be equal to: $(this).find('.selected_layout') because this already points to that element. You want it to point to the next element that comes after it.
I think this is what you are looking for:
$('input[type="radio"][name="selected_layout"]').change(function() {
if(this.checked) {
// get the index within the set of radio buttons for the radio button that was clicked
var idx = $("[type=radio][class=selected_layout]").index(this);
// Get the div structure that corresponds to the same index
var test = $("[class^='box_']")[idx];
// Now, just make that the value of the textarea
$('textarea').val(test.innerHTML);
}
});
textarea { width:100%; height:75px; }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form>
<label class="tp_box_1">
<input type="radio" name="selected_layout" id="sl1" class="selected_layout" value="layout_1">
<div class="box_1">
<h3>box_one</h3>
<p>1</p>
</div>
</label>
<label class="tp_box_2">
<input type="radio" name="selected_layout" id="sl2" class="selected_layout" value="layout_2">
<div class="box_2">
<h3>box_two</h3>
<p>2</p>
</div>
</label>
<textarea id="mytextarea"></textarea>
<input id="submit_form" type="button" value="Send">
</form>
Create div element with:
Template inside
class or id for identifying
Set inputs' value to desired template class/id, then on input change find the template element base on input's value and extract the innerHTML of it by using jQuery's .html() method. Then put this HTML as an new value of textarea using also the.html() method on textarea element.
HTML:
<div id="template1" style="display:none;">
<h1>Hi!</h1>
</div>
<input type="radio" onchange="findTemplate(event)" value="template1" />
<textarea class="texta"></textarea>
jQuery:
var findTemplate = function(event) {
var target = $(event.target);
var templateName = target.val();
var template = $("#"+templateName);
var template = template.html();
var textarea = $(".texta");
textarea.html(template);
};
Working fiddle: https://jsfiddle.net/rsvvx6da/1/
I have the following form :
<form class="form-inline" role="form">
<div class="col-xs-3">
<div class="pic-container">
<div class="checkbox">
<label>
<input type="checkbox" name="discounting" onchange='handleChange(this);' id='check11' > Show only price-discounted products
</label>
</div>
</div>
</div>
<div class="col-xs-3">
<div class="pic-container">
<div class="checkbox" id='check21'>
<label>
<input type="checkbox" name="discounting" onchange='' id='check21'> Show only price-discounted products
</label>
</div>
</div>
</div>
</form>
I'd like to be able to check the second checkbox automatically with JavaScript once I check the first one. I tried using the following script :
<script>
function handleChange(cb) {
if(cb.checked == true) {
alert('Message 1');
document.getElementById("check21").checked = true;
} else {
alert('Message 2');
var x = document.getElementById("check21").disabled= false;
}
}
</script>
But it doesn't work since I think with bootstrap is a question of classes.
The problem as Didier pointed out is that you have two elements with the same ID:
<div class="checkbox" id='check21'>
and
<input type="checkbox" name="discounting" onchange='' id='check21'>
The call to document.getElementById('check21') will probably (because the behavior is undefined) return the first one, which in this case is the <div> element, not the checkbox.
You must not use the same ID on two HTML elements, so you need to change the ID on one or the other of them.
http://jsfiddle.net/uywaxds5/2/
I included boostrap as an external reference.
<div class="checkbox" id='check22'>
<label>
<input type="checkbox" name="discounting" onchange='' id='check21'> Show only price-discounted products
</label>
</div>
Fixing the duplicate id seems to work.
If it does not works, the issue might be in another part of your code.
Use a different name for the second radio button
<input type="checkbox" name="discounting21">
There can only be one selected radio button belonging to the same group(ie. name).
I'm trying to check whether a check box is checked, and if it is checked, then I want to add the "required" attribute to an adjacent text field. I've tried it two different ways with no success. Here are the form elements and my two JQuery attempts.
neither of those will actually trigger the event. My browser either does nothing at all or triggers an "Empty string passed to getElementById()." event
Form elements:
<div class="col-sm-5">
<label id="checkboxNumber-label" class="toplabel" for="checkboxNumber">Checkbox</label>
<g:textField name="checkboxNumber" value="${...checkboxNumber}" class="form-control" required="" aria-labelledby="checkboxNumber-label"/>
<label class="checkbox-inline">
<g:checkBox name="checkboxYesNo" id="checkboxYesNo" value="${...checkboxYesNo}" onclick="chkboxYesChecked()"/>
</label>
</div>
<div class="col-sm-5">
<label id="someTextField-label" class="toplabel" for="someTextField">Some Text Field Here</label>
<g:textField name="someTextField" id="someTextField" value="${...someTextField}" class="form-control" aria-labelledby="someTextField-label"/>
</div>
JQuery:
function chkboxYesChecked(){
if($('#checkboxYesNo').prop('checked')){
$('#someTextField').prop('required',true);
$('#someTextField').append('<span class="required-indicator">*</span>');
}else{
$('#someTextField').removeAttr('required');
}
}
$(document).ready(function() {
$('#checkboxYesNo').click(function() {
if($(this).is(":checked"))
{
$('#someTextField').prop('required',true);
$('#someTextField').append('<span class="required-indicator">*</span>');
} else {
$('#someTextField').removeAttr('required');
}
});
});
With your markup this becomes more convoluted than it needs to be.
$(document).on("click", ".checkbox-inline :checkbox", function () {
var $nextTextbox = $(this).closest("div").next("div").find(":text").first();
if (this.checked) {
$nextTextbox.prop("required", true).after('<span class="required-indicator">*</span>');
} else {
$nextTextbox.prop("required", false).next('.required-indicator').remove();
}
});
Notes
This approach uses event delegation.
There are no IDs involved, because I suppose you need the same thing more than once on your page. Tying it to a specific element ID is counter-productive.
This approach relies on the specific document structure from your sample Grails template. If you want something more flexible and easier-to-read, change your HTML.
This applies to all checkboxes that have a text field in the immediately following <div>. Use CSS classes on your elements to filter it/make it apply to specific ones only.
If there is no immediately following <div> with a text box, the function does nothing.
$(this).is(":checked") is superfluous. You don't need jQuery to find out if the current DOM element is checked. this.checked is a lot simpler and has the same effect.
Don't use inline event handlers (onclick="..."). Ever.
See it in action:
$(document).on("click", ".checkbox-inline :checkbox", function () {
var $nextTextbox = $(this).closest("div").next("div").find(":text").first();
if (this.checked) {
$nextTextbox.prop("required", true).after('<span class="required-indicator">*</span>');
} else {
$nextTextbox.prop("required", false).next('.required-indicator').remove();
}
});
input[required] {
background-color: #FFD1D1;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="col-sm-5">
<label id="checkboxNumber-label" class="toplabel" for="checkboxNumber">Checkbox</label>
<input type="text" name="checkboxNumber" value="${...checkboxNumber}" class="form-control" required="" aria-labelledby="checkboxNumber-label" />
<label class="checkbox-inline">
<input type="checkbox" name="checkboxYesNo" id="checkboxYesNo" value="${...checkboxYesNo}" />
</label>
</div>
<div class="col-sm-5">
<label id="someTextField-label" class="toplabel" for="someTextField">Some Text Field Here</label>
<input type="text" name="someTextField" id="someTextField" value="${...someTextField}" class="form-control" aria-labelledby="someTextField-label" />

Project Focus
Toggle Checkbox(es)
Special Requirement
Need to bind the new(dynamically) added div.id container that holds these checkboxes. Note: this div.id has been dynamically generated (client-side).
Status
My Working Fiddle successfully toggles between 1(one) or 0(none) checkboxes.
The HTML
<div id="bind_id">
<input type="checkbox" name="iso_01[]" class="setTitlePre1" value="L/R" />
<label for name "iso_01" class="isoVar1">No.1</label>
<input type="checkbox" name="iso_01[]" class="setTitlePre2" value="Alt" />
<label for name "iso_01" class="isoVar2">No.2</label>
</div>
Working Script
var checkboxes;
checkboxes = $("input[name^=iso_01]").change(function (e) {
checkboxes.not(this).prop("checked", false);
}
});
Desired Result
I'm having trouble with syntax for updating .click() to .on("click","input..." see Bound Fiddle
Updated Script
var checkboxes;
checkboxes = $("#bind_id").on("change", "input[name^=iso_01]", function (e) {
if (this.checked) {
checkboxes.not(this).prop("checked", false);
}
});
Your issue is,
checkboxes = $("#bind_id").on
is not doing what you think it is doing. It is not storing all the matched nodes.
Try this instead:
In the callback, change
checkboxes.not(..)
to
$('input[name^=iso_01]').not(this).prop("checked", false);
Working fiddle
Or if they are loaded dynamically, you can use $('#bind_id').find('input[name^=iso_01]')
This is not what checkboxes are for. You should be using radio buttons:
<input type="radio" name="example" value="1" id="1">
<label for="1">one</label>
<input type="radio" name="example" value="2" id="2">
<label for="2">two</label>
The problem is checkboxes is the #bind_id element, not the checkboxes. You would need to find the children from that element, to get the child checkbox elements.
Working Example:
var wrapper;
wrapper = $("#bind_id").on("change", "input[name^=iso_01]", function (e) {
if (this.checked) {
wrapper.find("input[name^=iso_01]").not(this).prop("checked", false);
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div id="bind_id">
<input type="checkbox" name="iso_01[]" class="setTitlePre1" value="L/R" />
<label for name "iso_01" class="isoVar1">No.1</label>
<input type="checkbox" name="iso_01[]" class="setTitlePre2" value="Alt" />
<label for name "iso_01" class="isoVar2">No.2</label>
</div>
I need your help with my problem.
I created a static form. With a lots of and checkboxes. My problem is, I am integrating a javascript code for the selection of checkboxes. When the user check the parent checkboxes it will automatically check the subcategory. I can do this one by one (hardcoded). But it is a lot of work. What I think is I will put all of the IDs in an array and create a loop or event that will access them. But I don't know how. Ok that's all.
Here's my code: I am using CI and jquery 1.5
//here's the array
var checkboxParentMenu = ["checkAllFilipino","checkAllContinental","checkAllAsian","checkAllOthers"];
var checkboxChildMenu = ["filipino_cat","continental_cat","asian_cat","others_cat"];
Now here's the manual way.
$("input[data-check='checkAllFilipino']").change(function(){
$("#filipino_cat").find("input[type=checkbox]").attr("checked",this.checked);
});
Here's the pattern sample
<div id="parentTab">
<div id="categoryTab">
<input type="checkbox" />
</div>
<div id="subCategoryTab">
<input type="checkbox" />
</div>
<div id="childOfSubCategory">
<input type="checkbox" />
</div>
....
</div>
The super easy way out would be to actually nest the divs, then you could do this:
$('input[type=checkbox]').click(function () {
$(this).parent().find('input[type=checkbox]').attr('checked', $(this).attr('checked'));
});
HTML:
<div id="parentTab">
<div id="categoryTab">
<input type="checkbox" />
<div id="subCategoryTab">
<input type="checkbox" />
<div id="childOfSubCategory">
<input type="checkbox" />
</div>
</div>
</div>
</div>
One easy way out is
var checkboxParentMenu = ["checkAllFilipino", "checkAllContinental", "checkAllAsian", "checkAllOthers"];
var checkboxChildMenu = ["filipino_cat", "continental_cat", "asian_cat", "others_cat"];
$.each(checkboxParentMenu, function (idx, name) {
$('input[data-check="' + name + '"]').change(function () {
$("#" + checkboxChildMenu[idx]).find("input[type=checkbox]").attr("checked", this.checked);
});
})
But I would recommend
<input type="checkbox" data-check="checkAllFilipino" data-target="#filipino_cat" />CHECK ALL
<br/>
then
$('input').filter('[data-check="checkAllFilipino"], [data-check="checkAllContinental"], [data-check="checkAllAsian"], [data-check="checkAllOthers"]').change(function () {
$($(this).data('target')).find("input[type=checkbox]").attr("checked", this.checked);
});
Demo: Fiddle
Use prop() in place of attr() like,
var checkboxParentMenu = ["checkAllFilipino","checkAllContinental","checkAllAsian","checkAllOthers"];
var checkboxChildMenu = ["filipino_cat","continental_cat","asian_cat","others_cat"];
$.each(checkboxParentMenu ,function(i,parentChk){
$("input[data-check='"+parentChk+'").on(change',function(){
$('#'+checkboxChildMenu[i]).find("input[type=checkbox]").prop("checked",this.checked);
});
});
