I need to create some multiple input field dynamically on onkeypress event using JavaScript/jQuery.
I have one text-box,when user is entering any key on that text area two input field and second text-box is opening. When user will enter any key on second text box again another two input field and third text-box will open and so on. There is also a cross button is creating to close each individual set of text-box. In my current code I doing this putting all field static as user may create many numbers of input field so that I want to create those in dynamically with different name and id.
My code is in this Plunkr.

This can easily be done if you have a specific field in which to create the input fields. For example, I will load input fields into document.body
Everytime you call newinput() an input field is created in parent who's id starts at input0 and increments each time
var id = 0;
var newinput = function() {
var parent = document.body
var field = document.createElement("input")
field.className = "myclassname"
field.style = "display:block;"
field.id = "input" + id;
parent.appendChild(field);
id += 1;
}<body>
<div>Click plus to add input</div>
<button type="button" name="button" onclick="newinput()">+</button>
</body>In your case, it looks like you want to add a group, you can do this:
var fieldgroup = document.querySelector(".questionshowp .form-group").cloneNode(true); // (1)
var addinput = function(){
var parent = this.parentNode.parentNode.parentNode; // (2)
var n = parent.querySelectorAll(".form-control").length
var f = fieldgroup.cloneNode(true);
f.children[0].id = "question"+n // (3)
f.querySelector(".secondsec").querySelector("button.btn-success").onclick = addinput // (4)
parent.insertBefore(f,parent.querySelector(".clear")); // (5)
}
field-group to be used as a templateid with regard to total number of form-groups in parent addinput() to buttonThe easiest way apply this function to all + buttons is with JQuery
$("button.btn-sm.btn-success").on("click", addinput)
This would need to be located at the bottom of your html file, and below addinput() definition
Turns out I wrote all that and just realized I misunderstood your question. Still we can use the same principle to do what I believe you are asking
master = document.querySelector(".aquestionpart"); // (1)
form = document.querySelector(".questionparts"); // (2)
function show(){
var f = form.cloneNode(true);
var n = master.querySelectorAll(".questionparts").length;
f.id = "questionparts"+(n+1); // (3)
f.querySelector("#questions").onkeypress = show; // (4)
this.parentElement.parentElement.querySelector("#questionparts"+ n + " > .questionshowp").style ="display:block;"; // (5)
this.onkeypress = undefined; // (6)
master.insertBefore(f,master.children[master.children.length-1]) // (7)
}
form.querySelector("#questions").onkeypress = show; // (8)
form = form.cloneNode(true); // (9)
id with respect to number of others.clearWith this your current scripts.js is unnecessary, and .aquestionpart must look like this for proper formatting
<div class="aquestionpart">
<div class="questionparts" id="questionparts1">...</div>
<div class="clear"></div>
</div>
From within .questionparts be sure to remove onkeypress="show();" from input. It should look like this.
<input name="questions" id="questions" class="form-control" placeholder="Questions" value="" type="text">
And finally an interesting note is that both of the scripts I've provided can be used together! (With some slight modifications)

var addinput = function(){
var parent = this.parentNode.parentNode.parentNode;
var n = parent.querySelectorAll(".form-control").length
var f = fieldgroup.cloneNode(true);
f.children[0].id = "question"+n
f.querySelector(".secondsec").querySelector("button.btn-success").onclick = addinput
console.log(parent)
parent.insertBefore(f,parent.children[parent.children.length-1]);
}
master = document.querySelector(".aquestionpart");
form = document.querySelector(".questionparts");
function show(){
var f = form.cloneNode(true);
var n = master.querySelectorAll(".questionparts").length;
f.id = "questionparts"+(n+1);
f.querySelector("#questions").onkeypress = show;
console.log(this)
this.parentElement.parentElement.querySelector("#questionparts"+ n + " > .questionshowp").style ="display:block;";
this.onkeypress = undefined;
master.insertBefore(f,master.children[master.children.length-1])
$(f.querySelectorAll("button.btn-sm.btn-success")).on("click", addinput)
}
form.querySelector("#questions").onkeypress = show;
form = form.cloneNode(true);
$("button.btn-sm.btn-success").on("click", addinput)
If you put this in your scripts.js file and put that at the bottom of your body tag, then the only thing left is the - buttons.
You can use this Press to add multiple input field inside a div dynamically using jQuery. Here you only need to call the function that takes two parameter HTMLElement and config like:
$(".addInput").click(function() {
build_inputs($(this), config);
});
In the config you can add numbers of inputs form config like:
let config = {
title: "Slides",
forms: [
{
type: "text",
name: "name",
class: "form-control mb-2",
placeholder: "Enter Data..."
},
{
type: "file",
name: "image",
class: "btn btn-light btn-sm mb-2 btn-block"
},
{
type: "number",
name: "mobile",
class: "form-control mb-2",
placeholder: "Enter Data..."
}
],
exportTo:$('#getData')
};
