Multiple image upload and preview - javascript

I am learning how to upload multiple images and showing their preview...
I came across the following code
<html>
<head>
<style>
.input-file-row-1:after {
content: ".";
display: block;
clear: both;
visibility: hidden;
line-height: 0;
height: 0;
}
.input-file-row-1{
display: inline-block;
margin-top: 25px;
position: relative;
}
#preview_image {
display: none;
width: 90px;
height: 90px;
margin: 2px 0px 0px 5px;
border-radius: 10px;
}
.upload-file-container {
position: relative;
width: 100px;
height: 137px;
overflow: hidden;
background: url('images/picplus.png') top center no-repeat;
float: left;
margin-left: 23px;
}
.upload-file-container-text{
font-family: Arial, sans-serif;
font-size: 12px;
color: #719d2b;
line-height: 17px;
text-align: center;
display: block;
position: absolute;
left: 0;
bottom: 0;
width: 100px;
height: 35px;
}
.upload-file-container-text > span{
border-bottom: 1px solid #719d2b;
cursor: pointer;
}
.one_opacity_0 {
opacity: 0;
height: 0;
width: 1px;
float: left;
}
</style>
<script>
function readURL(input,target)
{
if(input.files && input.files[0])
{
var reader=new FileReader();
var image_target=$(target);
reader.onload=function(e)
{
image_target.attr('src',e.target.result).show();
};
reader.readAsDataUrl(input.files[0]);
}
}
$("patient_pic").live("change",function(){
readURL(this,"#preview_image")
});
</script>
</head>
<body>
<form name="" method="post" action="#" class="feedback-form-1">
<fieldset>
<div class="input-file-row-1">
<div class="upload-file-container">
<img id="preview_image" src="#" alt="" />
<div class="upload-file-container-text">
<div class = 'one_opacity_0'>
<input type="file" id="patient_pic" label = "add" />
</div>
<span> Add Photo </span>
</div>
<div class="upload-file-container-text">
<div class = 'one_opacity_0'>
<input type="file" id="patient_pic" label = "add" />
</div>
<span> Add Photo </span>
</div>
</div>
</div>
</fieldset>
</form>
</body>
</html>
I came across this JS Fiddle which explains it perfectly to me. But being a beginner I know it includes a jQuery library which clearly shows in framework extension of Fiddle. Now my issue is, how should I include it when I start the coding on my machine?
What will be included in the head (<script src="???">) section to make a call to the library?

Below is a working example of a solution to preview multiple uploaded image. (Source, Fiddle)
window.onload = function() {
//Check File API support
if (window.File && window.FileList && window.FileReader) {
var filesInput = document.getElementById("files");
filesInput.addEventListener("change", function(event) {
var files = event.target.files; //FileList object
var output = document.getElementById("result");
for (var i = 0; i < files.length; i++) {
var file = files[i];
//Only pics
if (!file.type.match('image'))
continue;
var picReader = new FileReader();
picReader.addEventListener("load", function(event) {
var picFile = event.target;
var div = document.createElement("div");
div.innerHTML = "<img class='thumbnail' src='" + picFile.result + "'" +
"title='" + picFile.name + "'/>";
output.insertBefore(div, null);
});
//Read the image
picReader.readAsDataURL(file);
}
});
} else {
console.log("Your browser does not support File API");
}
}
body {
font-family: ‘Segoe UI’;
font-size: 12pt;
}
header h1 {
font-size: 12pt;
color: #fff;
background-color: #1BA1E2;
padding: 20px;
}
article {
width: 80%;
margin: auto;
margin-top: 10px;
}
.thumbnail {
height: 100px;
margin: 10px;
}
<form id='post-form' class='post-form' method='post'>
<label for='files'>Select multiple files: </label>
<input id='files' type='file' multiple/>
<output id='result' />
</form>

First include Jquery library in your <head> section
<script src="http://code.jquery.com/jquery-1.8.3.js" type="text/javascript"></script>
Then below that
<script>
$(function(){
//Here your function
});
</script>
Change in your function use on instead of live
$("patient_pic").on("change",function(){
readURL(this,"#preview_image")
});
jQuery has deprecated live() since 1.7, instead use on()

Its as simple as :-
<html>
<head>
<script src="http://code.jquery.com/jquery-1.8.3.js" type="text/javascript"></script>
<script>
$(document).ready(function(){
//Your Code Goes Here
});
</script>
</head>
<body>
<!--Your H

unable to download multiple HTML element by html2canvas

I am trying to make a quote download system with div by html2canvas. But I have tried to make this system through this process. But it is not working.
Here are the Html multiple elements:
**First div:**
<div class="htmltoimage" style="background-color: skyblue;">
<!-- <img width="100px" src="raj2.jpg"> -->
<h1>Dhaka</h1>
<button onclick="downloadimage()" class="clickbtn">Download This</button>
</div>
**First div:**
<div class="htmltoimage" style="background-color: skyblue;">
<!-- <img width="100px" src="raj2.jpg"> -->
<h1>Dhaka</h1>
<button onclick="downloadimage()" class="clickbtn">Download This</button>
</div>
Here is the html2canvas code:
function downloadimage() {
var container = $(this).closest('.htmltoimage');
html2canvas(container, {allowTaint: true}).then(function (canvas) {
var link = document.createElement("a");
document.body.appendChild(link);
link.download = "html_image.jpg";
link.href = canvas.toDataURL();
link.target = '_blank';
link.click();
});
}
Note:
I have included the JQuery file and html2canvas link.
When someone clicks on the first div to download at this time only this div will be downloaded.
So on, and so on, and so on.....
Here's what I tried, You can download whole or one by one upon clicking on each element.
You need to select all the elements to download and then you can make a bunch download or fire Event Listener to get download one after other.
function download(url) {
var a = $("<a style='display:none' id='js-downloder'>")
.attr("href", url)
.attr("download", "test.png")
.appendTo("body");
a[0].click();
a.remove();
}
function saveCapture(element) {
html2canvas(element).then(function(canvas) {
download(canvas.toDataURL("image/png"));
})
}
var elements = document.querySelectorAll("#capture");
elements.forEach(function(element) {
element.addEventListener('click', function() {
saveCapture(element);
console.log(saveCapture(element));
})
})
//to download all
$('#btnDownload').click(function() {
var elements = document.querySelectorAll("#capture");
elements.forEach(element => {
saveCapture(element);
})
})
#import url('https://fonts.googleapis.com/css?family=Noto+Sans:400,700');
.mainContainer {
width: 500px;
height: 600px;
display: flex;
align-items: center;
flex-flow: column;
gap: 20px;
margin: 0 auto;
}
#capture {
margin: 0 auto;
width: 100%;
height: 100px;
overflow: hidden;
}
textarea {
width: 100%;
padding: 2rem .5rem;
border: 0;
text-align: center;
color: #fff;
background: slateblue;
font-family: 'Noto Sans', sans-serif;
font-weight: 700;
font-size: 2rem;
line-height: 1.5;
resize: none;
max-height: 100%;
min-height: 100%;
}
#btnDownload {
background-color: pink;
border: none;
color: #000;
padding: 15px 32px;
text-align: center;
text-decoration: none;
font-size: 16px;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/html2canvas/1.4.1/html2canvas.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="mainContainer">
Download
<div id="capture">
<textarea maxlength="110">Click to edit...</textarea>
</div>
<div id="capture">
<textarea maxlength="110">Click to remove...</textarea>
</div>
</div>
You can give it a try, it should work.

How to upload file images with button click

I am trying to create a small application that will allow me to create a tab image gallery. I have been able to successfully upload the image in the code below, but once the my image files are selected, they immediately show up in the allocated thumbnails. I still want the images to show up in the thumbnails, but only when a click even has occured. How do I create a function that will grab the files and then allocate them to the proper thumbnails with a button click? Any help would be appreciated. I am hoping to not use any php, I'm trying to keep a front end developer perspective on this. Thank you!

From my understanding you want the images to load when user clicks submit button, instead of upon file upload.
To do this copy the code from files.change(function(e) {} and paste int into the submit button click event.
For example:
$("#submit_btn").on("click", function () {
var files = $("input[type=file]");
files.each(function (e) {
if (this.files && this.files[0]) {
let thumb = $(this).data('thumb');
var reader = new FileReader();
reader.onload = function (e) {
$("." + thumb + " img").attr("src", e.target.result);
$('.full-image img').attr("src", e.target.result);
$("#avatar1").html(e.target.result);
}
reader.readAsDataURL(this.files[0]);
console.log(this.files[0]);
}
});
});
The code block $(window).on('load', function() { ... }); can then be deleted.

Javascript file partially running

So I taught myself coding a few years ago, and got it just enough to put together a few tools for work. I recently had to migrate my site out of CodePen and onto an actual web server. Now I'm having an issue where part of my javascript is executing properly (a portion that empties all other input fields when a user enters an input field using JQuery), but the button that calculates an answer will not work. I believe the .click is not picking it up. Either way I'm not getting error messages, the button just does nothing when I press it.
When I put the code in a snippet to share with you guys, it works (just like it did in CodePen), but the exact same code on my web host does not work. I'm really at a loss here and any help would be greatly appreciated. I feel like I'm missing some small line of code that's supposed to be included in all web files.
$(document).ready(function() {
//Clear out input fields when not selected
$("#sg").focusin(function() {
$("#density").val("");
});

save a dynamically created <textarea> tag using javascript ONLY

I am creating textarea tags as the user clicks a button. And i want the dynamically created texarea tags to remain as such when we close and open the browser again.
I am able to save the CONTENT of the textarea tag,but there is no point in it when the textarea tag itself doesnt remain after closing the browser.
ok: SO here is the code :
<!DOCTYPE html>
<html>
<head>
<title></title>
</head>
<body>
<button id="A" onclick="add()" type="button">ADD</button>
<button id="S" onclick="save()" type="button">SAVE</button>
<button id="E" onclick="edit()" type="button">EDIT</button>
<button id="D" onclick="del('x')" type="button">DELETE</button>
</body>
<script type="text/javascript">
var text_new,x;
var i=0,j,y;
function add()

Suggest you to try this.
Cookies are data, stored in small text files, on your computer.
When a user visits a web page, his name can be stored in a cookie.
Next time the user visits the page, the cookie "remembers" his name.

You can use html5 web storage, specifically the localStorage.

problems displaying Javascript message within <p>

I using jQuery-UI sortable which works fine. The problem that I am having is that the message "New order saved!" or "Save failed" is not displaying in the < p > area. The function is either not executing or something.
Below is the code for the .aspx page

The problem is with
success: function (data) {
if (data.d === "saved") {
$("<p>").text("New order saved!")
.addClass("success").appendTo("#left");
} else {
$("<p>").text("Save failed")
.addClass("failure").appendTo("#left");
}
},
Could someone tell me how to message display in the < p > area?
Any help would be greatly appreciated.
Thanks
Be sure to add the closing tag as well:
$("<p></p>").text("Save failed").addClass("failure").appendTo("#left");
Update: Also make sure the success function is even being called--Use a tool like Firebug (Firefox) or Developer tools in Chrome or Safari to inspect net traffic to see what the result of your call is.
You don't use brackets around the p inside the jquery function
try $('p')
Are you trying to update the single paragraph element already there? Or do you want to insert
a new paragraph element every single time. If you want the second case, just combine everything at once.
if (data.d === "saved") {
$("<p class='success'>New order saved!</p>").appendTo("#left");
}
else {
$("<p class='failure'>Save failed!</p>").appendTo("#left");
}
