Hello I am trying to add new form field and delete form field after getting inspired from this tutorial - http://bootsnipp.com/snipps/dynamic-form-fields
My Current Problem is to delete and reset the value of all in chronological order.
<input type="hidden" name="count" value="1" />
<div class="control-group" id="fields">
<label class="control-label" for="field1">Nice Multiple Form Fields</label>
<div class="controls" id="profs">
<div class="input-append">
<input autocomplete="off" class="span3" id="field1" name="prof1" type="text" placeholder="Type something (it has typeahead too)" data-provide="typeahead" data-items="8"
data-source='["Aardvark","Beatlejuice","Capricorn","Deathmaul","Epic"]'/><button id="b1" onClick="addFormField()" class="btn btn-info" type="button">+</button>
</div>
<br /><small>Press + to add another form field :)</small>
</div>
</div>
Javascript :-
var next = 1;
function addFormField(){
var addto = "#field" + next;
next = next + 1;
var newIn = '<br /><br /><input autocomplete="off" class="span3" id="field' + next + '" name="field' + next + '" type="text" data-provide="typeahead" data-items="8"><button id="b1" onClick="$(this).parent().remove();" class="btn btn-info" type="button">+</button>';
var newInput = $(newIn);
$(addto).after(newInput);
$("#field" + next).attr('data-source',$(addto).attr('data-source'));
$("#count").val(next);
}
Parent Element is getting removed, but next counter is not reset properly. in hidden and all new created form :-
Only Add Demo :- http://bootsnipp.com/snipps/dynamic-form-fields
Add an Delete Demo with Bug :- http://jsfiddle.net/6dCrT/2/
Can someone help me please.
Thanks
Try:
function addFormField(){
var addto = "#field" + next;
next = next + 1;
var newIn = '<br /><br /><input autocomplete="off" class="span3" id="field' + next + '" name="field' + next + '" type="text" data-provide="typeahead" data-items="8"><button id="b'+next+'" onClick="$(this).prev().remove();$(this).remove();" class="btn btn-info" type="button">-</button>';
var newInput = $(newIn);
console.log(addto);
$(addto).after(newInput);
if(next>1)
$("button#b"+next).after(newInput);
$("#field" + next).attr('data-source',$(addto).attr('data-source'));
$("#count").val(next);
}
DEMO FIDDLE
In my example, I was building a form that would allow users to add multiple input names if they had more than one dog.
var counter = 0
jQuery(function () {
$(".newDog").click(function(){
counter ++;
if (counter < 4) {
var elem = $("<input/>",{
type: "text",
name: `dogname${counter}`
});
} else {
alert("You can only add 4 Dog Names")
}
var removeLink = $("<span/>").html("X").click(function(){
$(elem).remove();
$(this).remove();
counter --;
});
$(".dogname-inputs").append(elem).append(removeLink);
});
})

My goal is that only 15 quantities of input elements can be accepted, once the user enters 16 it should say that only 15 input elements is allowed. However I don't know how will I do this. I tried putting condition inside for but it is not not working. I am a little bit confused on this
Here is my HTML code
<div class="form-group">
<label> Quantity: </label>
<input class="form-control" name="quantity" type="number" id="get_Elem"
required>
<br>
<input type="button" id="sb_add_ctrl" name="is_Sub" class="btn btn-
primary" value="Add Control Number">
</div>
<div class="form-group" name="parent" id="parent"></div>
Here is my JS code
$(document).on('click', '#sb_add_ctrl', function() {
var element = $('#get_Elem').val();
var input;
var parent = $(document.getElementById("parent"));
var value = $('#sel_control_num').val();
functionPopulate(parent);
if (isNaN(element)) {
return;
}
for (var i = 0; i < element; i++) {
if(should I do it here??){
}
value = value.replace(/(\d+)$/, function(match, element) {
const nextValue = ++match;
return ('0' + nextValue).slice(1);
});
document.getElementById("parent").style.padding = "5px 0px 0px 0px";
document.getElementById("parent").innerHTML += '<br><input type="text"
value="' + value +
'" class="form-control" name="get_Input_show[]" required>'
}
});
You can check if the element value is < 16 if yes then only add html else show error message.
Demo Code :
$(document).on('click', '#sb_add_ctrl', function() {
var element = $('#get_Elem').val();
var input;
//var value = $('#sel_control_num').val();
var value = 12;
//functionPopulate(parent);
if (isNaN(element)) {
return;
}
//check if elemnt value if < 16
if (element < 16) {
$("#parent").empty() //empty div
for (var i = 0; i < element; i++) {
/* value = value.replace(/(\d+)$/, function(match, element) {
const nextValue = ++match;
return ('0' + nextValue).slice(1);
});*/
document.getElementById("parent").style.padding = "5px 0px 0px 0px";
document.getElementById("parent").innerHTML += '<br><input type="text" value = "' + value + '" class="form-control" name="get_Input_show[]" required>';
}
} else {
alert("only 15") //show error
}
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="form-group">
<label> Quantity: </label>
<input class="form-control" name="quantity" type="number" id="get_Elem" required>
<br>
<input type="button" id="sb_add_ctrl" name="is_Sub" class="btn btn-
primary" value="Add Control Number">
</div>
<div class="form-group" name="parent" id="parent"></div>
There are two ways in which you can restrict it
You can use maxLength property of an input tag, which will restrict the user to input the 16th character.
You can keep checking the value in the input field and show error if the length is more than 15 character. To do this you can use onkeypress event on input, like
HTML
<input type="text" id="test" onkeypress="test()" />
JS:
<script>
function test() {
alert('Hi')
}
</script>
I have an html form. Whenever i click add button another copy of it appends. Whenever i click add button, id of my elements increases such as username_0, username_1, username_2... There are 2 radio buttons on my form that whenever i choose second radio button, a hidden textarea appears. Problem is i'm having problem with choosing my dynamic id's of radio buttons. I made a function but its only working for first element since i can't get dynamic id's
<label for="evetKontrol_0">Evet</label>
<input type="radio" id="evetKontrol_0" name="uygun_0" onclick="javascript:yesnoCheck();" value="uygun" checked>
<label for="hayirKontrol_0">Hayır</label>
<input type="radio" id="hayirKontrol_0" name="uygun_0" onclick="javascript:yesnoCheck();" value="uygunDegil">
<div id="ifNo_0" style="visibility:hidden">
<strong>Uygun Olmama Sebebi:</strong> <input type="textarea" id="hayirSebep_0" name="hayirSebep" style="height: 75px"><br>
</div>
function yesnoCheck() {
if (document.getElementById('evetKontrol_0').checked) {
document.getElementById('ifNo_0').style.visibility = 'hidden';
}
else document.getElementById('ifNo_0').style.visibility = 'visible';
}
I need to be able to get my evetKontrol_#somenumber for my function for every copy of my form.
JSfiddle/ all of my code
I tried to use jQuery( "[attribute*='value']" ) but i couldn't manage to work it out.
Consider the following.
Working Example: https://jsfiddle.net/Twisty/sonvakq2/21/
JavaScript
$(function() {
function addElement(tObj) {
var counter = $("[id^='ogrenci']", tObj).length;
var html = '<div class="col-auto" id="ogrenci_' + counter + '"><label for="ad">Ad</label><input type="text" name="ad[]" class="form-control" id="ad_' + counter + '" placeholder="Öğrencinin Adı"/><label for="soyad">Soyad</label><input type="text" name="soyad[]" class="form-control" id="soyad_' + counter + '" placeholder="Öğrencinin Soyadı"/><label for="no">No</label><input type="text" name="numara[]" class="form-control" id="no_' + counter + '" placeholder="Öğrencinin Numarası"><label for="course">Bölümü</label><input type="text" name="bolum[]" class="form-control" id="course_' + counter + '" placeholder="Öğrencinin Bölümü"><label for="alKredi">Almak İstediği Kredi</label><input type="text" name="alKredi[]" class="form-control" id="alKredi_' + counter + '" placeholder="Almak İstediği Kredi"><label for="verKredi">Alabileceği Kredi</label><input type="text" name="verKredi[]" class="form-control" id="verKredi_' + counter + '" placeholder="Alabileceği Kredi"><label for=""><strong>Uygun mu?</strong> </label><br><label for="evetKontrol_' + counter + '">Evet</label><input type="radio" id="evetKontrol_' + counter + '" name="uygun_' + counter + '" value="uygun" checked><label for="hayirKontrol_' + counter + '">Hayır</label><input type="radio" id="hayirKontrol_' + counter + '" name="uygun_' + counter + '" value="uygunDegil"><div id="ifNo_' + counter + '" style="visibility:hidden"><strong>Uygun Olmama Sebebi:</strong> <input type="textarea" id="hayirSebep_' + counter + '" name="hayirSebep" style="height: 75px"><br></div><div class="input-group-addon"><span class="glyphicon glyphicon glyphicon-remove" aria-hidden="true"></span> Remove</div></div>';
tObj.append(html);
}
function showHidden() {
$("[id^='evetKontrol']").each(function(i, el) {
var rel = $("#ifNo_" + i);
if ($(el).is(":checked")) {
rel.show();
} else {
rel.hide();
}
});
}
//add more fields group
$("#add").click(function() {
addElement($("#container"));
});
//remove fields group
$('#container').on('click', "a[id^='remove']", function() {
$(this).parents('div.col-auto').remove();
});
$("#container").on("click", "input[type='radio']", showHidden);
});
Your fiddle wasn't configured properly, so I addressed that first. I moved a lot of the repeatable items into Functions. Switched it all the jQuery and removed any of the local javascript calls.
You can see examples of how to use the Attribute selector in a relative manner to select items you want.
See More: https://api.jquery.com/category/selectors/attribute-selectors/
You shouldn't need to use IDs for this. Just capture the onclick event and pass a boolean to determine if the hidden input should be shown. If you have multiple inputs to show and hide separately, you could pass the ID of the input along with the boolean.
function yesnoCheck(show) {
var ta = document.getElementById('hiddenTA');
if (show) {
ta.style.visibility = 'visible';
} else {
ta.style.visibility = 'hidden';
}
}
<label for="user1_0">User 1</label>
<input type="radio" name="users" id="user1_0" onclick="yesnoCheck(false)" checked />
<label for="user2_0">User 2</label>
<input type="radio" name="users" id="user2_0" onclick="yesnoCheck(true)" />
<input style="visibility:hidden" id="hiddenTA" />
In order to get the evetKontrol_#somenumber, pass that number in the onclick function.
In your JSfiddle, this would mean concatenating the counter variable into the function parameters like
... onclick="javascript:yesnoCheck(' + counter + ');" ...
Then update the function to use that value:
function yesnoCheck(counter) {
if (document.getElementById('evetKontrol_' + counter).checked) {
document.getElementById('ifNo_' + counter).style.visibility = 'hidden';
} else {
document.getElementById('ifNo_' + counter).style.visibility = 'visible';
}
I'm creating a set of textboxes and some drop downs using jQuery. The add function is working with out any issues.
My problem is with the delete function function works nicely as long as the user deletes one after the other but if the user delete from some where else the number sequence get messed up. Which breaks the 1,2,3,4 ... etc and sets the number which was deleted last.
As an example if the user deletes number 4 out of 7 errors the functions sets the last number as 4 when the user clicks the add button the next number generated will be 5 not the correct last number. I want to rest the rest of the numbers when something get removed from the middle.
I'm storing the last number in a hidden filed called stValue which is getting reset when deleting.
My problem is here I can't get my head around to think of way to reset this when deleting from some where else and then reset the entire error number row numbers when something get removed from the middle. Can you guys help me with this below is my code.
jsFiddle will help to understand better

$(".errorCount").each(function(index, _this) {

I am using this code to generate dynamically ADD More input fields and then plan on using Save button to save their values in database. The challenge is that on Save button, I want to keep displaying the User Generated Input fields. However they are being refreshed on Save button clicked.
javascript:
<script type="text/javascript">
var rowNum = 0;
function addRow(frm) {
rowNum++;
var row = '<p id="rowNum' + rowNum + '">Item quantity: <input type="text" name="qty[]" size="4" value="' + frm.add_qty.value + '"> Item name: <input type="text" name="name[]" value="' + frm.add_name.value + '"> <input type="button" value="Remove" onclick="removeRow(' + rowNum + ');"></p>';
jQuery('#itemRows').append(row);
frm.add_qty.value = '';
frm.add_name.value = '';
}
function removeRow(rnum) {
jQuery('#rowNum' + rnum).remove();
}
</script>
HTML:
<form method="post">
<div id="itemRows">Item quantity:
<input type="text" name="add_qty" size="4" />Item name:
<input type="text" name="add_name" />
<input onclick="addRow(this.form);" type="button" value="Add row" />
</div>
<p>
<button id="_save">Save by grabbing html</button>
<br>
</p>
</form>
One approach is to define a template to add it dynamically via jQuery
Template
<script type="text/html" id="form_tpl">
<div class = "control-group" >
<label class = "control-label"for = 'emp_name' > Employer Name </label>
<div class="controls">
<input type="text" name="work_emp_name[<%= element.i %>]" class="work_emp_name"
value="" />
</div>
</div>
Button click event
$("form").on("click", ".add_employer", function (e) {
e.preventDefault();
var tplData = {
i: counter
};
$("#word_exp_area").append(tpl(tplData));
counter += 1;
});
The main thing is to call e.preventDefault(); to prevent the page from reload.
You might want to check this working example
http://jsfiddle.net/hatemalimam/EpM7W/
along with what Hatem Alimam wrote,
have your form call an upate.php file, targeting an iframe of 1px.
The form below is working as I want except for one thing. When I click the 'Add' link I the texts of all the textboxes go back to its default value like seen in the images. How can I fix it? Thanks.
before click:
after click on 'Add':
Code:
function addSection() {
var str = '<div>' +
'<input type="text" name="composer" value="Compositor" />' +
'<input type="text" name="peca" value="Peca" size="40" />' +
'<input type="button" value="x" style="width: 26px" onclick="delSection(this)" /><br />' +
'</div>';
document.getElementById("programa").innerHTML += str;
}
function delSection(field) {
field.parentNode.outerHTML = "";
}
window.onload = addSection;
</script>
<fieldset>
<legend>Programa</legend>
<div id="programa">
</div>
<a href="#" onclick="addSection()" >Add</a><br />
</fieldset>
<input type="submit" value="Inscrever Aluno" name="submit" />
You can overcome this, using appendChild()
JS
function newSet() {
var div = document.createElement("div");
var composer = document.createElement("input");
composer.type="text";
composer.value = "Compositer";
var peca = document.createElement("input");
peca.type = "text";
peca.value = "Peca";
var button = document.createElement("input");
button.type = "submit"
div.appendChild(composer);
div.appendChild(peca);
div.appendChild(button);
return div
}
function addSection() {
document.getElementById("programa").appendChild(newSet());
}
Demo
This is the correct JS to insert new elements:
function addSection() {
var newDiv = document.createElement('div');
var str = '<input type="text" name="composer" value="Compositor" />' +
'<input type="text" name="peca" value="Peca" size="40" />' +
'<input type="button" value="x" style="width: 26px" onclick="delSection(this)" /><br />';
newDiv.innerHTML = str;
document.getElementById("programa").appendChild(newDiv);
}
You need to find a solution for naming (or identification) of the elements so you can remove them with delSelection(field)
create a name like name="composer[]" and name="peca[]"
