I want to display a particular image as many times as the number given by user.This part is accomplished. But i want to display a number below each image. For example if user input is 4, there should be 4 images with '1' below 1st image '2' below second. The image must also be clickable.
<!DOCTYPE html>
<html>
<body>
<p>Click the button to add a new element to the array.</p>
<input type="number" id="myNumber" value="">
<button onclick="imag()">Try it</button>
<div id="demo">
<script>
function imag(c,x) {
var x = document.getElementById("myNumber").value;
var c="<img src='C:/Users/Akhil/Desktop/New folder/G.jpg'/>";
var arr = [];
for (var i = 0; i < x; i++) {
arr.push(c);
document.getElementById("demo").innerHTML = arr.join("  ");
}
}
</script>
</body>
</html>
var imageSrc = "http://fc08.deviantart.net/fs71/f/2010/148/1/9/20x20_PNG_Icons_DOMO_by_JMcIvor.png";
function imag(c,x) {
var x = document.getElementById("myNumber").value;
var demo = document.getElementById("demo");
var container = document.createElement("div");
container.setAttribute("class", "container");
for(var i=0; i<x; i++) {
var image = document.createElement("img");
image.setAttribute("class", "image");
image.setAttribute("src", imageSrc);
container.appendChild(image);
var text = document.createElement("div");
text.innerHTML = i+1;
container.appendChild(text);
demo.appendChild(container);
}
}
#demo {
}
.container {
}
.image {
}
.text {
}

I just use another image url to test the code, replace it with your one. I hope this helps.
You already have the number you're looking for in your loop. So you can simply add it to your array like this.
JS:
function imag() {
var x = document.getElementById("myNumber").value;
var c = "<img src='C:/Users/Akhil/Desktop/New folder/G.jpg'/>";
var arr = [];
for (var i = 0; i < x; i++) {
arr.push("<div class='image'>" + c + "<br />" + (i+1) + "</div>");
}
document.getElementById("demo").innerHTML = arr.join("  ");
}
CSS:
div.image {
display: inline-block;
}

I'm working on a code for extract information from an .json file and print it on a website. I achived all but now I have a problem, the data is showing only 1 result, it create all boxes/places for the other information but only the first "box" have information.
<head>
<!-- Title and Extern files -->
<title>SSL Checker</title>
<link rel="stylesheet" type="text/css" href="css/style.css">
<script type="text/javascript" src="js/db.json"></script>
</head>
<body>
<div id="header">
<h2>SSL Checker</h2>
</div>
<div id="form">
<p>Introduce the URL:</p>
<input id="txtbx" type="text">
<button type="submit" onClick="agregar_caja()">Send</button>
<div id="inf">
<p type="text" id="hl1"></p>
<p type="text" id="hl2"></p>
</div>
<script>
//Extract
console.log(MyJSON[1].url)
var cajas = 2
var boxsaved = MyJSON.length
fnc = function(info) {
hey = document.getElementById("hl1").innerHTML = info.url;
}
//box creator
sm = function agregar_caja() {
document.getElementById("inf").innerHTML += "<p type=text id='hl" + new String(cajas + 1) + "'><br>"
cajas = cajas + 1
}
//Loops
for (i = 0; i < boxsaved; i++) {
sm(MyJSON[i]);
}
for (i = 0; i < MyJSON.length; i++) {
fnc(MyJSON[i]);
}
</script>
</body>
And .json file:
var MyJSON = [{
"url": 'google.es',
},
{
"url": 'yahoo.com',
}]
The problem is that your first box is the only element that your fnc function alters - notice that it only uses the hl1 id to access and alter an element, never hl2+.
I'll try to keep to your original approach, so that you'll follow it more easily. You might do something like this:
var cajas = 2;
function sm(info) {
cajas = cajas + 1;
document.getElementById("inf").innerHTML += (
'<div id="hl' + cajas + '">' + info.url + '</div>'
);
}
for (var i = 0; i < MyJSON.length; i++) {
sm(MyJSON[i]);
}
It is very difficult to read all the code, but as i've got it, you want to add some elements with url's from your JSON.
Ok, we have parent element div with id='inf', lets use javascript function appendChild to add new elements.
And we will use document.createElement('p') to create new elements.
Here is the code, as I've understood expected behavior.
var infContainer = document.getElementById('inf');
var elNumber = 2;
function agregar_caja() {
MyJSON.forEach(function(item,i) {
var newElement = document.createElement('p');
newElement.innerHTML = item.url;
newElement.id = 'hl'+elNumber;
elNumber++;
infContainer.appendChild(newElement);
}
)}
I am trying to make it where when the user clicks the demo section toggles the flag value each time.
I was under the impression that the static variable was myFunction.flag and it would remain constant throughout the page each time it changes...
<!DOCTYPE html>
<html>
<body>
<p>Search a string for "w3Schools", and display the position of the match:</p>
<button onclick="myFunction()">Try it</button>
<p id="demo"></p>
<script>
function myFunction() {
var str = "Visit W3Schools!";
var n = str.search(/w3Schools/i);
myFunction.flag = 1;
if(myFunction.flag){
document.getElementById("demo").innerHTML = myFunction.flag;
myFunction.flag = 0;
} else {
document.getElementById("demo").innerHTML = myFunction.flag;
myFunction.flag = 1;
}
}
</script>
</body>
</html>
You are creating a new variable each time a click happen.
Just make it global.
<script>
var flag = 0;
function myFunction() {
var str = "Visit W3Schools!";
var n = str.search(/w3Schools/i);
if(flag){
document.getElementById("demo").innerHTML = myFunction.flag;
flag = 0;
} else {
document.getElementById("demo").innerHTML = myFunction.flag;
flag = 1;
}
}
</script>
And thanks in advance for looking into this, I am trying to show elements of 2 arrays in html (li) tags. This should be the format echoed out:
array1; array2
c201;100
c202;0
c450;320
......
The elements that will be pushed into the array are coming from input fields. I have created the following code and I get to see the correct format but when I copy and paste the values above, it loses the format and instead of having two columns, it pastes elements of array2 just below the elements of array1:
<!doctype html>
<html>
<head>
<meta charset="UTF-8">
<title>My Web Page</title>
<script>
var array_accounts = [];
var array_credits = [];
var x = 0;
var i = 0;
var z = 0;
function spara(){
var accounts_code_str = document.getElementById('accounts').value;
var accounts_code_comma = accounts_code_str.split(' ');
var accounts_code_comma = accounts_code_comma.join(';<br>');
array_accounts.push(accounts_code_comma);
console.log(array_accounts);
var iz_credits_str = document.getElementById('credits').value;
var iz_credits_comma = iz_credits_str.split(" ");
//var iz_credits_comma = iz_credits_comma.join('<br> ');
for(var z=0; z<iz_credits_comma.length; z++){
if(iz_credits_comma[z] < 0){
iz_credits_comma[z] = 0;
}
}
var iz_credits_comma = iz_credits_comma.join('<br> ');
array_credits.push(iz_credits_comma);
showAccounts();
showCredits();
}
</script>
</head>
<body>
<h1>Accounts and IZ credits</h1>
<div id="form">
<form>
<label>Insertar Accounts codes</label>
<input type="text" name="accounts" id="accounts" />
<label>Insertar Iz credits</label>
<input type="text" name="credits" id="credits" />
<input type ="button" onclick="spara()" value="Process data" />
</form>
</div>
<div id="codes" style="float:left">
<script>
function showAccounts(){
for (var x=0;x<array_accounts.length;x++){
document.write('<div style="float:left;">'+array_accounts[x]+';</div>');
}
}
</script>
</div>
<div id="credits" style="float:left">
<script>
function showCredits(){
for (var i=0;i<array_credits.length;i++){
document.write('<div style="float:left;">'+array_credits[i]+'<br></div>');
}
}

Modify the two javascript functions and that should do the trick! Thanks.
I want to input the amount of array and the output will follow as it's amount.
Ex: If I put "7" in the input text. the result will show as much as 7.
Here's my code:
<html>
<head>
<title>JavaScript - Input Text Field</title>
</head>
<body>
<form name="test">
<H2>Enter something into the field and press the button. <br></H2>
<P>Amount of Tables: <input type="TEXT" name="amount"><BR><BR>
<input type="Button" Value="Show and Clear Input" onClick="myFunction()"></P>
</form>
<p id="demo"></p>
<script>
function myFunction() {
var text = "";
var i;
var j = document.getElementsByName("amount");
for (i = 0; i < j.length; i++) {
text += "The number is " + i + "<br>";
}
document.getElementById("demo").innerHTML = text;
}
</script>
</body>
</html>
You have something wrong on your JavaScript
See code:
function myFunction() {
var text = "";
var i;
var j = document.getElementsByName("amount")[0];
for (i = 0; i < j.value; i++) {
text += "The number is " + j.value + "<br>";
}
document.getElementById("demo").innerHTML = text;
}
.getElementsByName returns an array of elements, so you need to specify the index of your element so that you can access its properties.

So i am pretty new at this and want to be able to add a dollar to the "deposit" text box every time I click the button. I'm going to have to do this with a quarter, dime, and nickel, button as well. This is what I have so far.
<input type="button" value="Dollar" id="dollar" />
$<input type="text" id="deposit" />
And the javascript is:
var $ = function (id) { return document.getElementById(id); }
var item = [];
var total = 0;
for (i=0; i < item.length; i++){
total += item[i];
$("deposit").value = total;
}
$("dollar").onclick = item.push(1);
Whatever help you can give is much appreciated!
Don't you mean
Live Demo
var $ = function (id) { return document.getElementById(id); }
var add = function(fld,val) {
return (parseFloat(fld.value)+val).toFixed(2);
}
window.onload=function() {
$("dollar").onclick=function() {
$("deposit").value = add($("deposit"),1);
}
$("dime").onclick=function() {
$("deposit").value = add($("deposit"),.1);
}
$("nickel").onclick=function() {
$("deposit").value = add($("deposit"),.05);
}
$("refund").onclick = function() {
$("deposit").value = "0.00";
}
}
Try this:
HTML
<!DOCTYPE html>
<html>
<head>
<script data-require="jquery#1.9.1" data-semver="1.9.1" src="//ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
<script src="script.js"></script>
</head>
<body>
<input type="button" value="Dollar" id="dollar" />
$ <input type="text" id="deposit" />
</body>
</html>
JavaScript:
$(function() {
var item = [];
$("#dollar").click(function() {
item.push(1);
var total = 0;
for (var i = 0; i < item.length; i++) {
total += item[i];
$("#deposit").val(total);
}
});
});
