add new textbox and buttons with javascript

add new textbox and buttons with javascript - javascript

I have 3 textboxs and 6 buttons. I want to add new textbox and buttons after textbox(element2) and buttons(element2) with javascript. How can I do it. :)
<input type="text" id="element1">
<input type="button" id="element1">
<input type="button" id="element1">
<input type="text" id="element2">
<input type="button" id="element2">
<input type="button" id="element2">
<input type="text" id="element3">
<input type="button" id="element3">
<input type="button" id="element3">

Since Ids should be unique, I'll modify your HTML code :
<div id="div">
<input type="text" id="text1">
<input type="button" id="button1a">
<input type="button" id="button1b">
<input type="text" id="text2">
<input type="button" id="button2a">
<input type="button" id="button2b">
<input type="text" id="text2">
<input type="button" id="button2a">
<input type="button" id="button2b">
</div>
And the script would look like this :
<script>
var text2_new = document.createElement("input");
var div= document.getElementById("div");
var button2b= document.getElementById("button2b");
div.insertBefore(text2_new,button2b);
</script>
Repeat the the script for every new element you need to add.
In your context I'd place the group of inputs inside of <div> tags to delimit the groups.

How can I delete line breaks and text inputs dynamically with JavaScript?

I created a small website where I would like to add/remove input fields dynamically. I already wrote the code to add them and it works perfect but removing the input fields is a bit of a challenge.
Below is what my document looks like after creating the inputs. Now with the "remove button" I tried to remove the last BR and the 3 inputs fields above, but whatever I try I always remove the last 3 buttons, which is ok, and both brs above and beneath the three inputs.
var total_inputs = 9;
var place_br_before = false;
function remove_inputs() {
if (total_inputs != 0) {
place_br_before = true;
for (var j = 0; j < 3; j++) {
var del = document.getElementById(("input_" + total_inputs));
del.remove();
total_inputs--;
}
$('#inputs br:last-child').remove();
}
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
<button type="button" onclick="add_inputs()">+</button>
<button type="button" onclick="remove_inputs()">-</button>
<form id="inputs">
<input type="text" id="input_1">
<input type="text" id="input_2">
<input type="text" id="input_3">
<br>
<input type="text" id="input_4">
<input type="text" id="input_5">
<input type="text" id="input_6">
<br>
<input type="text" id="input_7">
<input type="text" id="input_8">
<input type="text" id="input_9">
<br>
</form>

I would probably simplify and abstract out the ID requirement by grouping rather than using line breaks.
function remove_inputs() {
inputGroups = document.getElementsByClassName('input-group');
inputGroups[inputGroups.length - 1].remove();
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
<button type="button" onclick="add_inputs()" disabled>+</button>
<button type="button" onclick="remove_inputs()">-</button>
<form id="inputs">
<div class="input-group">
<input type="text">
<input type="text">
<input type="text">
</div>
<div class="input-group">
<input type="text">
<input type="text">
<input type="text">
</div>
<div class="input-group">
<input type="text">
<input type="text">
<input type="text">
</div>
</form>

Getting values inside jquery from input fields with dynamic id

I want to get value of input fields with dynamic id to jquery function
<input type="text" id="a_8" name="a_8" value="12">
<input type="text" id="b_8" name="b_8" value="22">
<button type="button" class="btn btn-success" onclick="javascript:det(8);">Submit</button>
<input type="text" id="a_9" name="a_9" value="22">
<input type="text" id="b_9" name="b_9" value="52">
<button type="button" class="btn btn-success" onclick="javascript:det(9);">Submit</button>
Jquery function
function det(a)
{
//how can I get values of id a_8,b_8 when first button is clicked
and a_9,b_9 values when second button is clicked
}

you can simply create id of your control by appending method argument a to a_ or b_ like $("#a_"+a).val()
function det(a)
{
alert($("#a_"+ a ).val());
alert($("#b_"+ a ).val());
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<input type="text" id="a_8" name="a_8" value="12">
<input type="text" id="b_8" name="b_8" value="22">
<button type="button" class="btn btn-success" onclick="javascript:det(8);">Submit</button>
<input type="text" id="a_9" name="a_9" value="22">
<input type="text" id="b_9" name="b_9" value="52">
<button type="button" class="btn btn-success" onclick="javascript:det(9);">Submit</button>

function det(a){
var b1 = $('#a_'+a).val();
var b2 = $('#b_'+a).val();
console.log('values: '+b1+','+b2);
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<input type="text" id="a_8" name="a_8" value="12">
<input type="text" id="b_8" name="b_8" value="22">
<button type="button" class="btn btn-success" onclick="javascript:det(8);">Submit</button>
<input type="text" id="a_9" name="a_9" value="22">
<input type="text" id="b_9" name="b_9" value="52">
<button type="button" class="btn btn-success" onclick="javascript:det(9);">Submit</button>

Create form after index.php&value=1

Hello I have this form code as shown below
<td>
<form action="pay/index.php">
<input type="submit" class="btn btn-primary">
<input type="hidden" value="1.00" name="amount">
</form>
</td>
The result is index.php?amount=1.00, I want to create
index.php?amount=1.00&value=1
How should I add &value=1 after it?

When you use method="GET", which is the default, all the named inputs become URL parameters. So you just need to add another hidden input with the name value.
<form action="pay/index.php">
<input type="submit" class="btn btn-primary">
<input type="hidden" value="1.00" name="amount">
<input type="hidden" value="1" name="value">
</form>

I want the value of my button to appear in a textbox upon clicking the button

I am creating an onscreen keyboard, and want a function which will allow when any of the buttons are pressed, for their values to appear in a text box to the side of the keyboard. The code I have so far is:-
<script type="text/javascript">
function onclick(){
document.getElementById("output").value
=document.getElementById("Q").value;
}
</script>
And the HTML code below:-
<div class ="Row">
<div class="Box2">
<form id="keyboard" name="keyboard">
<div>
<input type="button" onclick='onclick' id="Q" value="Q">
<input type="button" value="W">
<input type="button" value="E">
<input type="button" value="R">
<input type="button" value="T">
<input type="button" value="Y">
<input type="button" value="U">
<input type="button" value="I">
<input type="button" value="O">
<input type="button" value="P">
</div>
<div>
<input type="button" value="A">
<input type="button" value="S">
<input type="button" value="D">
<input type="button" value="F">
<input type="button" value="G">
<input type="button" value="H">
<input type="button" value="J">
<input type="button" value="K">
<input type="button" value="L">
</div>
<div>
<input type="button" value="Z">
<input type="button" value="X">
<input type="button" value="C">
<input type="button" value="V">
<input type="button" value="B">
<input type="button" value="N">
<input type="button" value="M">
</div>
<div>
<input type="button" value="SPACE">
<input type="button" value="ENTER">
</div>
</form>
<input type='text' id='output' />
</div>
</div>
</div>

You have it tagged as jQuery, so here is a more elegant jQuery solution: Throw that code away and use a single delegated jQuery event handler. Start with something like this:
$('[name=keyboard]').on('click', 'input[type=button]', function(){
var value = $(this).attr('value');
$('#output').val($('#output').val() + value);
});
JSFiddle: https://jsfiddle.net/TrueBlueAussie/kaau601u/
Obviously you need to handle the SPACE and ENTER as special cases, but you gave no clues what you are doing next, so leaving that to the reader to finish :)
Notes:
You either need to place this code after the elements it references or put it in a DOM ready handler.
Like this:
$(function(){
$('[name=keyboard]').on('click', 'input[type=button]', function(){
var value = $(this).attr('value');
$('#output').val($('#output').val() + value);
});
});
Or you can use a document attached handler, which is always present:
Like this:
$(document).on('click', 'input[type=button]', function(){
var value = $(this).attr('value');
$('#output').val($('#output').val() + value);
});

//Please try this working example
$('#Q').click(function(){
$('#output').val($(this).val());
console.log($(this).val());
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class ="Row">
<div class="Box2">
<form name=keyboard name="keyboard">
<div>
<input type="button" id="Q" value="Q">
<input type="button" value="W">
<input type="button" value="E">
<input type="button" value="R">
<input type="button" value="T">
<input type="button" value="Y">
<input type="button" value="U">
<input type="button" value="I">
<input type="button" value="O">
<input type="button" value="P">
</div>
<div>
<input type="button" value="A">

<div>
<input type="button" value="SPACE">
<input type="button" value="ENTER">
</div>
</form>
<input type='text' id='output' />
</div>
</div>

I have made a slight change in the output field type with working SPACE and ENTER
jQuery('form[name="keyboard"] input[type="button"]').click(function(){
var inpVal = jQuery(this).val();
if( inpVal == "SPACE" ){
inpVal = ' ';
}else if( inpVal == "ENTER" ){
inpVal = '\n';
}
var val = jQuery('#output').val() + inpVal;
jQuery('#output').val(val);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div class ="Row">
<div class="Box2">
<form name=keyboard name="keyboard">

<input type="button" value="ENTER">
</div>
</form>
<textarea id="output" cols="40" rows="5"></textarea>
</div>
</div>
</div>

This might help
//this this the script that makes it happen...
$('form[name=keyboard]>div>input[type=button]').click(function(){
$('#output').val($(this).val());
console.log($(this).val());
})

Using just javaScript and no need for jQuery.
This example including the use of the SPACE and ENTER keys. As a bonus I added a BACKSPACE key.
Note your output text field was changed to text area to allow for the use of the enter key.
Create a single event listener for the form. This can be done using document query selector.
Capture the click event with the query selector.
Note on the <body> tag we add the onload event handler so when the document is served up the event listener is assigned to the <form> node.
Any click inside the <form> will be tested
HTML and javaScript
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<html lang="en">
<head>
<script type="text/javascript">
var g = {};
function assignListener()
{
/*event listener for keyboard*/
g.keyboard = document.querySelector("#keyboard");
g.keyboard.addEventListener("click", addToTextBox,false);
}
function addToTextBox(e)
{
/*
with query selector the event (e) is passed along
to the function. You can examine the event and get
all kinds of useful stuff from it, like type of event, where it came from, attributes like id, class list etc.
*/
if (e.target.type == 'button')
{
switch (e.target.value)
{
case "ENTER":
document.getElementById('output').value += '\n';
break;
case "SPACE":
document.getElementById('output').value += ' ';
break;
case "BACKSPACE":
document.getElementById('output').value = document.getElementById('output').value.substr(0,document.getElementById('output').value.length-1);
break;
default:
document.getElementById('output').value += e.target.value;
}
}

Make CSS popup dissapeer when blanket is clicked (Example: Facebook Photo's)

i have a css popup div that when it loads through the onClick it also brings up a blanket of transparency kind of like how Facebook does when you look at photos
How do i get that popup div to close when i click on the blanket?
Heres the code
'
<center><div id="blanket" style="display:none;">
</div>
<table width="1000" border="0">
<tr>
<td>
<div id="mainAdminCP">
<div class="editRecipe" >
<h2>Edit Recipe</h2>
</div>
<div id="popUpAdminEditRecipe" style="display:none;" align="center">
<br />
<br />
<form id="editRecipe">
<fieldset id="inputs">
<input id="username" type="text" placeholder="Please insert the name of the recipe" autofocus required>
<br />
<br />
<input id="add" type="text" placeholder="Recipe Name" required>
<input id="add" type="text" placeholder="Recipe Ingredients" required>
<input id="add" type="text" placeholder="Recipe Instructions" required>
<input id="add" type="text" placeholder="Recipe Image" required>
</fieldset>
<fieldset id="actions">
<input type="submit" id="submit" value="Save Changes">
<input type="submit" id="submit" onClick="popup('popUpAdminEditRecipe')" value="Close">
</fieldset>
</form>
</div>
<div class="editCoins">
<h2>Edit Coins</h2>
</div>
<div id="popUpAdminEditCoins" style="display:none;" align="center">
<br />
<br />
<form id="login">
<fieldset id="inputs">
<input id="username" type="text" placeholder="Please insert the Username of the User" autofocus required>
<input id="add" type="text" placeholder="Add Coins" required>
<input id="add" type="text" placeholder="Subtract Coins" required>
</fieldset>
<fieldset id="actions">
<input type="submit" id="submit" value="Submit">
<input type="submit" id="submit" onClick="popup('popUpAdminEditCoins')" value="Close">
</fieldset>
'
And heres the link to the page itself to get a clear example of what im looking for.
http://teknologenie.com/fruitforest/admincp.php
Ive tried placing the
<a href="#" onClick="popup('popUpAdminEditUser')" > </a>
Within the blanket div, and nothing. Just kind of screws everything up.
Edit:
Also if you visit the link, and click the text, the whole div doesnt get directly in the middle of the screen and i need it to be. Any solutions?

Instead of putting an link inside the blanket div, pup an onclick function on the blanket div itself:
<div id="blanket" onclick="closePopup()" style="height: 681px; display: block;"></div>
The function closePopup should then set display none to the popup and the blanket:
function closePopup() {
document.getElementById('blanket').style.display = 'none';
document.getElementById('popUpAdminEditCoins').style.display = 'none';
}

I've written you an example here: http://jsfiddle.net/KXK6E/2/
You'd be much better off binding events within the javascript rather than within the HTML.
document.getElementById("blanket").onclick = function(e){
document.getElementById("popup").style.display = "none";
e.target.style.display = "none";
};
document.getElementById("trigger").onclick = function(){
document.getElementById("blanket").style.display = "block";
document.getElementById("popup").style.display = "block";
}
