Here I need to delete the last textarea ('in this case 2nd box') always. Check javascript below.
function deleteQuestionField(){
var textareas = $('#container textarea');
console.log('hii',textareas);
if (textareas.length !== 0) {
textareas.last().remove();
}
}
This function is called from a button click event but its not deleting the last textarea.
Simply use jQuery's .remove() (see here for more info):
Give your div that you want to remove a unique id and then call it:
HTML:
....
<!-- question 2nd box starts here -->
<div class="col-md-4" id="someUniqueId">
....
Javascript:
function deleteQuestionField(){
var textareas = $('#container textarea');
console.log('hii',textareas);
if (textareas.length !== 0) {
$("#someUniqueId").remove(); //This will remove the unique id element
}
}
You have the html() function in jQuery
http://api.jquery.com/html/ to remove all codes between an element
The remove() function you used delete the selected element
If you want to delete the content of the textarea, try to use the val() function instead.http://api.jquery.com/val/
$('textarea').val('');
If I understand it correctly if the first textarea is not empty you want to remove the second 'box' . If this is the case you should select the first textarea and not textarea in general (I assume)
firstly add an ID to the second div <div class="col-md-4" id="remove_this"> and call the ID in the remove function
So probably it would be something like:
function deleteQuestionField(){
var textareas = $('#questions0'); //if you want general just use textarea ( `$('#container textarea');`)
console.log('hii',textareas);
if (textareas.length !== 0) {
$("#remove_this").remove();
}
}
Documentation about the .remove function HERE
You want to delete total div ,but you are making delete only textarea element
textareas.last().remove();
//change above code to like below ,it will delete the whole div
$(".col-md-4").last().remove();
With Jquery
$("#item_id").empty();
It works

Given some html, a form named InterfacesIx and a button named addInterfacesIx
<div class="step-new-content white-text">
<p class="text-monospace"><small>helps you rollout a configlet about blahblah</small></p>
<form name="InterfacesIx">
<div class="row">
<div class="md-form col-12">
<input type="text" name="xxx" class="form-control white-text" placeholder="123"><label for="xxx">asn</label>
</div>
<div class="md-form col-12">
<textarea name="yyy" class="md-textarea form-control white-text" rows="3"></textarea><label for="yyy">notes</label>
</div>
</div>
<br><br><br>
</form>
<div class="col-12 text-center">
<button type="button" name="addInterfacesIx" class="btn btn-block btn-flat"><i class="fas fa-plus"></i></button>
</div>
</div>
I would like to clone/duplicate the form when the user clicks on the addInterfacesIx button using jQuery I guess.
The jQuery that I am trying looks like this:
<script>
$(document).ready(() => {
$('addInterfacesIx').click(function(){
$('InterfacesIx').clone().insertBefore('addInterfacesIx');
});
});
</script>
When I do console.log($('InterfacesIx')); nothing gets printed out. Is the selector wrong ?
When inspecting the form element on the browser I get:
copy attribute shows name="InterfacesIx"
copy selector path shows #stepper-navigation > li > div.step-new-content.white-text > form
copy xml shows //*[#id="stepper-navigation"]/li/div[2]/form
Would you be so kind to advise what I am doing wrong and how to achieve the desired result ?
Your selector $('addInterfacesIx') is not valid. If you want to grab an element by name you should use attribute selector, something like this: $( "form[name='addInterfacesIx']"). However, as mentioned before, grabbing element by class or ID is definitely better.
$('addInterfacesIx') and $('InterfacesIx') aren't valid selectors. I'd suggest putting id/class attributes on the relevant elements and then selecting them by that.
I also assume that the form elements should be siblings, as such try using insertAfter() and placing the new form after the last one currently in the DOM. Your current logic would place the new form inside the button container. Try this:
jQuery(($) => {
$('#addInterfacesIx').click(function() {
$('.interfacesIx:first').clone().insertAfter('.interfacesIx:last');
});
});

You are confusing the fact that a name attribute is not normally used as a jQuery selector - the name attribute is normally used for keys to form values when they are submitted to the server. You can select elements using the name attribute, as indicated by the code below, but using id and class attributes is preferred.
<form id="InterfacesIx" name="InterfacesIx">
...
</form>
<div class="col-12 text-center">
<button type="button" id="addInterfacesIx" class="btn btn-block btn-flat"><i class="fas fa-plus"></i></button>
</div>
<script>
$(document).ready(() => {
$('#addInterfacesIx').click(function(){
// $('#InterfacesIx') is better
$('[name=InterfacesIx]').clone().insertBefore('addInterfacesIx');
});
});
</script>
I have a form on the page and displayed it as none. And there is a button in the page I want when clicking on the button the form to display.
How can I do that?
<button type="button" class="btn btn-primary add-city">اضافه مدينة جديدة +</button>
and form code is this
<div id="forma">
<div class="form-head">
<p id="add-city">+اضافة المدينة</p>
<i class="fa fa-times-circle close" aria-hidden="true"></i>
</div>
<form class="">
<div class="container">
<div class="row">
<div class="col-md-6">
<div class="form-group">
<label>الدولة<span>*</span></label>
<select class="form-control">
<option>اختر الدوله </option>
</select>
</div>
<div class="form-group">
<label>اسم المدينه(عربي)<span>*</span></label>
<input type="text" class="form-control" id="email">
</div>
</div>
<div class="col-md-6">
<div class="form-group ">
<label>المحافظة<span>*</span></label>
<select class="form-control">
<option>اختر المحافظه </option>
</select>
</div>
<div class="form-group">
<label>اسم المدينه(انجليزي)</label>
<input type="text" class="form-control" id="email">
</div>
</div>
</div>
</div>
</form>
<div class="form-footer">
<button type="button" class="btn btn-primary">ارسال</button>
<button type="button" class="btn btn-secondary">الغاء</button>
</div>
</div>
I made a div with an id called forma so that I can call it in javascript. But I don't know the right way.
You can add an onclick attribute to the button that changes the display to block.
onclick="document.getElementById('forma').style.display = 'block'"
Just use the jQuery click property and show property
$( "#idbutton" ).click(function() {
$("#idform").show();
});
If you are using Bootstrap.js, you can safely use jQuery because it's required. Assuming you should click #add-city button to display the form, simply add to your app.js or inside your <script> tags
$('#add-city').click(function() {
$('#forma').show();
});
In order to toggle the form (show/hide) on every click, you could do something like
$('#add-city').click(function() {
$('#forma').toggleClass('hidden');
});
I have a one text box search, and one button,when i add the text and click button, related data will be getting but when i click another search.that is taking same id,previous id not clearing. how to clear that id
<div class="col-lg-4 col-sm-4 col-xs-12">
<i class="glyphicon glyphicon-search"></i>
<div class="form-group">
<input type="text" class="form-control" id="isbncollegeid" data-ng-model="isbncollege" placeholder=" Search By college ISBN" name="isbncollegeid">
</div>
</div>
<div class="col-sm-4">
<br />
<div class="form-group">
<input type="hidden" id="bookcollgeIsbn" name="bookcollgeIsbn" />
<button type="button" class="btn btn-sky" id="IsbntcolDetails" data-ng-disabled="LibraryIsbnForm.$invalid" data-ng-click="DetailscolByISBN()">Get Details<i class="fa fa-exclamation"></i>
</button>
<button type="button" class="btn btn-sky" id="clear" data-ng-click="ClearISbnCollege()">Clear<i class="fa fa-exclamation"></i>
</button>
</div>
</div>
In your ClearISbnCollege just make isbncollege model empty
$scope.ClearISbnCollege = function() {
$scope.isbncollege = "";
}
When you will click the Clear button, input will be emptied.
You can use below line of code after getting results in javascript:
document.getElementById('elementid').value = "";
in Jquery:
$('#elementid').val("");
When I click duplicate it duplicates the row fine, but when I click it again I get another 2, then 4 etc, how can I stop this from happening and just clone one div on each click...
Jquery:
<script>
$(".clonable-button").bind('click', function(e){
e.preventDefault();
var section = $(this).data('clone');
var parent = $('[data-id="' + section + '"]');
var sequence = 0;
if(!$(this).data('last')) {
sequence = $(parent).find('.cloneable').last().data('id');
} else {
sequence = $(this).data('last');
}
$(this).data('last', ++sequence);
$(parent).append(parent.html());
});
$('.clone-wrapper').on('click', '.clone-remove',function(){
var parent = $(this).parents('.cloneable');
$(parent).remove();
});
</script>
html:
<div class="clone-wrapper" data-id="skill">
<div class="row cloneable" data-id="0">
<div class="col-md-9">
<div class="form-group">
<label for="skill_name_0">Skills and Qualifications Titles </label>
<input id="skill_name_0" placeholder="ex : PHP, WordPress" name="skill[0][name]" type="text" class="form-control" value="">
</div>
</div>
<div class="col-md-3">
<div class="form-group">
<label for="skill_percentage_0">Job Position </label>
<input id="skill_percentage_0" placeholder="ex : 90" name="skill[0][percentage]" type="text" class="form-control" value="">
</div>
</div>
<div class="col-md-12 text-right clone-remove" data-last="">
<div class="btn btn-danger btn-sm" data-clone="skill">
<i class="fa fa-times"></i> Remove Skill </div>
</div>
</div>
</div>
<div class="white-space-20"></div>
<div class="row text-right">
<div class="col-md-12">
<div class="btn btn-default btn-sm clonable-button" id="skill">
<i class="fa fa-plus"></i> Add Skill </div>
</div>
</div>
I just want the following code duplicated once on each click
<div class="row cloneable" data-id="0">
<div class="col-md-9">
<div class="form-group">
<label for="skill_name_0">Skills and Qualifications Titles </label>
<input id="skill_name_0" placeholder="ex : PHP, WordPress" name="skill[0][name]" type="text" class="form-control" value="">
</div>
</div>
<div class="col-md-3">
<div class="form-group">
<label for="skill_percentage_0">Job Position </label>
<input id="skill_percentage_0" placeholder="ex : 90" name="skill[0][percentage]" type="text" class="form-control" value="">
</div>
</div>
<div class="col-md-12 text-right clone-remove" data-last="">
<div class="btn btn-danger btn-sm" data-clone="skill">
<i class="fa fa-times"></i> Remove Skill </div>
</div>
</div>
The problem is in this line:
var parent = $('[data-id="' + section + '"]');
Each time you append new block with the same data-id number of elements that match this selector increases. So to avoid this you have make the selector more specific. Like:
var parent = $('[data-id="' + section + '"]:last');
Also there is a jQuery method to clone the element. So change your line from:
$(parent).append(parent.html());
to:
parent.append(parent.clone());
That will fix the issue.
You are binding the click event multiple times somehow, You should either use a delegated event handler or use the off method like below.
$(".clonable-button").off('click').on('click', function(e){
I want to remove a dynamically generated div using jquery, remove button will be with every div. So when I click any remove button, it will remove that div from DOM.
<div class="form-group" id="drag">
<div class="col-md-2">
<input type="text" class="form-control" id="name1" placeholder="Name">
</div>
<div class="col-md-2">
<input type="text" class="form-control" id="eng1" placeholder="Description Eng">
</div>
<div class="col-md-2">
<input type="text" class="form-control" id="ar1" placeholder="Description Ar">
</div>
<div class="col-md-2">
<a id="remove" href="javascript:;" class="btn btn-sm red">
Remove
<i class="fa fa-close"></i>
</a>
</div>
</div>
If you would generate a div with inside the div a button, you can add the following function to let that button make the parent div disappear:
function removeParent()
{
//remove button click, remove the parent div from the dom
$(this).parent().parent().remove();
//in your specific case you want the parent parent div to be removed since the button is encapsulated by 2 divs.
}
This function you then need to add to the onclick listener of the button. Either by just setting it in the html onclick='removeParent()' or using javascript:
//gerenate div + button
mybutton.addEventListener('click', removeParent, false);
$('body').on('click', '#remove', function(){
$(this).closest('.form-group').remove();
});
But it's not correct to have more than one elements with the same id. recomment you to change ID to class
Try like below. Use class remove instead of id, because id should be unique.
$('body').on('click', '.remove', function(){
$(this).closest('.form-group').remove();
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="form-group" id="drag">
<div class="col-md-2">
<input type="text" class="form-control" id="name1" placeholder="Name">
</div>
<div class="col-md-2">
<input type="text" class="form-control" id="eng1" placeholder="Description Eng">
</div>
<div class="col-md-2">
<input type="text" class="form-control" id="ar1" placeholder="Description Ar">
</div>
<div class="col-md-2">
<a class="remove" href="javascript:;" class="btn btn-sm red">
Remove
<i class="fa fa-close"></i>
</a>
</div>
</div>
