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');

You can give it a try, it should work.

I have a button of fixed size and various chunks of text. The length of the texts is different. How can I make the size of the text font change dynamically according to its length in order to fit the button boundaries properly? Thank you.
Well, depends. Is the height fix as well? If both height and width are fixed, you will have to calculate the fontsize via javascript.
In most of the cases two or three if conditions should be absolutely sufficient for the specific usecase.
function font_size_adjust () {
// Grab the string
var string = $('#button_text').text()
// Get the length in characters of the string
var string_size = string.length
// Build variable to change attribute
var font_size = 0
// Define logic for resizing, adapt this to your personal needs
if (string_size < 60) {
fontsize = '2vw';
} else if (string_size > 60) {
fontsize = '4vw';
} else {}
// Change fontsize
$('#button_text').css('font-size', fontsize)
}
// Call the function where- and whenever needed:
font_size_adjust();
// Example stuff
$('#toggle_small').click(function () {
$('#button_text').text('Now I am small again!')
font_size_adjust();
})
$('#toggle_big').click(function () {
$('#button_text').text('Now I am large again! Lets get this rollin! rollin! rollin! rollin!')
font_size_adjust();
})

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()
{
text_new=document.createElement("textarea");/*I WANT TO STORE THESE CREATED TAGS USING LOCAL STORAGE*/
text_new.id="a"+i.toString();
var t = document.createTextNode("");
text_new.appendChild(t);
console.log(text_new.id);
i++;
document.body.appendChild(text_new);
}
document.body.addEventListener("click", activate);
function activate()
{
if(document.activeElement.tagName.toLowerCase() ==="textarea")
{
x = document.activeElement.id;
y=x;
console.log(x);
console.log(typeof x);
}
}
function save()
{
document.getElementById(x).readOnly=true;
console.log(document.getElementById(x).value);
localStorage.y=document.getElementById(x).value;
document.getElementById(x).value=localStorage.y;
}
function edit()

}
function del()

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.
https://www.w3schools.com/js/js_cookies.asp
You can use html5 web storage, specifically the localStorage.

I hope this Helps!

Hey earthlings,
i started learning HTML and CSS. Currently I'm dealing with style classes. I created a simple example. What I want to reach is, that the titlebar changes the font color, the font-size and the background color if button1 is clicked.
Initially the titlebar has appended the titlebar-class, after button1 is clicked the darktitle-class should also be added and overwrite certain attributes.
However in this configuration it doesn't happen. If you change the order of the .darktitle and .titlebar class in css file it works. I wonder why.
The CSS Styles should be on the same priority level, so I would expect that the laterly assigned would overwrite the attributes.
TNX
you can use !important to override styles like this
.darktitle {
color: #000000!important;
background: grey!important;
font-size: 25px!important;
}
#charset "utf-8";
html, body {
margin: 0px;
font-family: Helvetica, sans-serif;
min-height: 100%;
height: 100%;
}
.center-container {
display: flex;
align-items: center;
justify-content: center;
height: 100%;
/*height: 500px;*/
}
.main-container {
/*height: 100%;*/
}
.titlebar {
text-align: center;
color: #FF0000;
background: blue;
font-size: 40px;
}
.darktitle {
color: #000000;
background: grey;
font-size: 25px;
}
button {
padding: 00px;
font-weight: bold;
font-size:1em;

color: #000000;

The order of your css selectors matter when both selectors are being applied to the same element. Move the ".darktitle" below the ".titlebar" as in this example. Then when applied by the button the ".darktitle" sstyles will override those same properties in ".titlebar".
Please take a look at this link about CSS specificity, there you will read about your question and why not to use !important declaration.

I use for a project Font Awesome for icons and because they do not show in IE8 when I use it like:
<i class="fa fa-bars fa-2x"></i>
I am forced to use the cheat sheet icons as this:
<i class="mobile-search-icon fa fa-lg"></i>
This way, the icons show OK in IE8 as well.
Now, the problem... Using the cheat sheet icons, how can I replace the value with another on toggle? Please check the example below where you see initially the search icon and on click I should see a close icon and on another click, show again the search icon.
The example below is the closest way I have found so far, and I need some help if possible. Thanks
$(".mobile-search-icon").on('click', function(e) {
$(this).siblings(".search-container").fadeToggle(500);
if ($.trim($(this).text()) === '') {
$(this).text('');
} else {
$(this).text('');
}
return false;
});

Not sure exactly what you want, but it looks neat. I made a demo that uses FA's Unicode on Snippet 1.
I re-read your question, I think I understand ... You just want to toggle the button between 2 icons. If so look at Snippet 2. Your problem is that you are using .text() method which will add non-parsed plain text. .html() will take text and parse it to HTML so it's rendered as what the text represents, and not what it is literally.

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
