drag and upload multiple images in a box in angular

drag and upload multiple images in a box in angular - javascript

Any best example is there for drag and upload the image in angularjs or angular any version? I didn't find anything in angular.
jsfiddle
I have this example, But my requirement is, I have one + button in a box. If I drag and drop any image on that + button it should upload and one more box should open next to that box. Please see the image.
Like this I need to upload more images. If any fiddle or examples are there, please anyone send me.

</div>

Let's agree about some steps:
To support multiple images in the scope, obviously, you should keep an array of images.
We want to re-use the dropzone so after a user will drop an image to it, the image will be next to it and the user could drop another image. So, we don't want to handle the scope, we will parse the file (src and name) and call a callback onDrop with these parameters, and the control itself will handle it.
Please, read my comment in the code

It could be a little complex change in the line of thought. If anything is not clear, let me know.

What do we do if we want to insert multiple images uploaded by dragdrop in one line at a time?

i used by javascrip upload multiple file but that files insert different columns.
Why is it that when uploading multiple files with drag drop, they are written in multiple rows instead of one line in the database?
Pictured is a view of the data after inserting it into the database
My php Code is : uploads.php
if(isset($_FILES)){
$upload_dir = "upload/";
$fileName = strtolower(pathinfo($_FILES["files"]["name"], PATHINFO_EXTENSION));
$new_file_name = rand() . '.' . $fileName;
$uploaded_file = $upload_dir.$new_file_name;
if(move_uploaded_file($_FILES['files']['tmp_name'],$uploaded_file)){
}
$content = $_POST['textpost'];
$data = array(
':file' => $new_file_name,
':uploaded_on' => date("Y-m-d H:i:s"),
':content' => $content,
);
$query = "
INSERT INTO images
(name, uploaded_on ,content)
VALUES (:name,:uploaded_on,:content)
";
$statement = $connect->prepare($query);
$statement->execute($data);
}
The Below is the code I originally used. I used these codes as examples from other people’s codes. Then I made some changes myself and added a little functionality. For example, I added a few codes, such as deleting images, separating images and videos, and brought them to the function I needed. But the problem with me now is that When uploading multiple images at the same time as text, All data sent are insert into separate rows, Finally when I select the data from the database the content and images are not select out correctly.My goal is to insert images and text into a single line.
My javascript Code is :index.html
var dropRegion = document.getElementById("drop-region"),
// where images are previewed
imagePreviewRegion = document.getElementById("image-preview");
var file_drag_area = document.getElementById("file_drag_area");

For your case, when you drag and drop the files (file upload), you will trigger the following function:
function handleFiles(files) {
for (var i = 0, len = files.length; i < len; i++) {
if (validateImage(files[i]))
previewAnduploadImage(files[i]);
}
}
It is obvious that this "handleFiles" function will process the files one by one. Hence the php is called ONCE for every file uploaded --- and that explains why the files are saved into separate records.
The above should explain what you encounter. So if you want to save the data into a single record, you need to amend the above codes

Bootstrap 2.3.2 overlapping divs in grid on browser window resize

I have two divs that are overlapping using Bootstrap's 2.3.2 grid system when the browser is resized. The result looks like the following after you downsize the browser window:
I don't want the two divs to ever overlap. If it comes to a point where they cannot fit on the same row, the second div should fall below the first, which the responsive layout is already doing. My problem is those weird few pixels where they overlap.
I'm using Bootstrap's tags input library here.
The HTML:
<div class="container-fluid">
<div class="row-fluid">
<div class="span12" style="border: 1px solid black;">
<div class="span1 offset4" style="border: 1px solid blue;">
<select id="container" multiple data-role="tagsinput"> </select>
</div>
<div class="span2 offset2" style="border: 1px solid red;">
<h4>
Second Div
</h4>
<div id="second_div">
<p>
testing...... 1 ... 2 ... 3...
</p>
</div>
</div>
</div>
</div>
</div>
JavaScript to populate some dummy data:
$(document).ready(function() {
$('select').tagsinput('add', 'Foo');
$('select').tagsinput('add', 'Bar');
$('select').tagsinput('add', 'This is a very very very very very very long filter');
});
And my CSS:
.small {
font-size: 10px;
}
.tag {
/*height: 25px;*/
vertical-align: middle;
line-height: 25px;
/*width: 75%;*/
word-wrap: break-word;
white-space: normal;
}
ul {
list-style-type: none;
}
.top-margin {
margin-top: 5px;
}
.bootstrap-tagsinput {
width: 200px;
max-width: none;
}
I have a jsfiddle which demos the problem here: https://jsfiddle.net/brseyg6c/

The problem is not Bootstrap but instead this declaration:
.bootstrap-tagsinput {
width: 200px;
max-width: none;
}
You're fixing the width of the tag container while it's inside a dynamically sized Bootstrap column.
Instead, have the container fill the width of the column:
.bootstrap-tagsinput {
box-sizing: border-box;
width: 100%;
}
You might want to increase the width of the left column (change span1 to be larger) and remove the offset from the right column.

I have two idea for you.
Trick 1: Can you make it like this with out media query just replace the off-set2 and make offset3. and add this into class .bootstrap-tagsinput .tag white-space:pre-wrap; .otherwise in snippet large tag came out of the box. Trick 2 Fiddle

Trouble displaying Native Ads in Mobile Web in AngularJS view

In my AngularJS application I am attempting to add a Facebook Native Web Ad to one of my views. I followed the steps outlined in the documentation to generate the necessary HTML snippet and added this to my view.
My application is using ui-router to resolve routes. When visiting the route/view containing this code snippet the FB ad is not displayed and neither of the callbacks are invoked (onAdLoaded or onAdError).

I noticed that the Facebook Audience Network JS is loaded asynchronously and suspected that I might have a race condition causing the issue.
<script type="text/javascript" src="https://connect.facebook.net/en_US/fbadnw.js" async></script>
To test this, I've moved the FB code snippet out of my view and into my SPA index.html. The ad appears as expected. What callback does the fbadnw.js script call once the script is loaded? Is the closure within the FB generated code being invoked before fbadnw.js is loaded perhaps?
index.html (works)

I was able to resolve this issue by editing the boilerplate code provided by FB. In a nutshell, the provided closure (minified) attempts to:
Locate the iframe element where the Ad will be rendered and set it's
src and other attributes.
Attach an event handler to listen for post messages "message".
Initialize the Ad with FB Audience Network (ADNW.init())
My problem was with the assumptions this code makes in Step 1.
var b = d.currentScript || (function() {
var c = d.getElementsByTagName('script');
return c[c.length - 1];
})();
var e = b.parentElement;
The above code is attempting to locate this DIV.
<div style="display:none; position: relative;">
It does this by first trying to locate the parent of the last script element on the page. This is brittle and, in my case, did not work. The last script element added in my document was not the one this code expected.
I modified this code to explicitly select the correct element by ID.
Added an ID to containing DIV:
<div id="fb-ad-container" style="display:none; position: relative;">
Simplify the DOM parsing code (step 1) to select this DIV by ID:
var e = d.getElementById("fb-ad-container");
By selecting the correct element by ID I was able to alleviate the need to locate the current script element. The rest of the script ran as expected.

How transfer files (or folders) via Ajax by d'n'd?

I want to upload folder to server by d'n'd via AJAX. But already, I have troubles with upload files.
I use e.dataTransfer.items and webkitGetAsEntry() to check - is it file or folder?
If it's file, in function traverseFileTree I get file, but I can't append it to formData.
If I use e.dataTransfer.files, I don't know what is it. File or Folder because webkitGetAsEntry() get error.
What I do wrong?

Both file() and readEntries() return results asynchronously. Since it is impossible to know for certain how many files or directories, which themselves could contain additional directories containing still more files or folders, will be selected and dropped by user, the a single or recursive calls to traverseFileTree require some mechanism to determine when all asynchronous operations have completed. This can be achieved using one or more of several approaches.
The present approach increments a variable n, pushes each individual file to an array uploads. If n is 0, process the first file; increment n so that its value 1 greater than the array containing files .length until the array .length is equal to n - 1
uploads.length === n - 1 || n === 0
then copy uploads array using .slice(), set uploads.length and n to 0, pass array of files to function processFiles where files are appended to FormData() object, call to XMLHttpRequest() is made.

Links in Top-Fixed Navigation Bar Not Responding

I am using a little Javascript navigation bar for my single-page site. All of my text links work just fine, but the outbound social media links on the right side are not responding (unless you secondary-click and open it from there). Now, I am just barely knowledgable in JQuery and Javascript...I can understand it and how it works but when it comes to errors I can't figure it out. Thank you for helping! :)
Here is my CSS:
.single-page-nav {
background: rgb(255, 255, 255);
background: rgba(255, 255, 255, .9);
padding: 1.25em 0;
box-shadow: 0px 2px 8px #555;
position: fixed;
top: 0;
left: 0;
width: 100%;
z-index:100000;
}
.single-page-nav ul {
list-style: none;
padding: 0;
margin: 0 auto;
margin-left: -30px;
width: 80%;
overflow: hidden;
}
.single-page-nav li {
float: left;
width: 16%;
text-align: center;
}
.single-page-nav a {
display: block;
color: #000;
font-family: 'Calibri', Helvetica, Sans-Serif;
text-decoration: none;
font-size: 18px;
font-weight: bold;
line-height:1.5em;
}
.single-page-nav a:hover,
.single-page-nav .current {
color: #F92F2C;
}
Here is my HTML
<nav id="menu" role="navigation">
<div class="single-page-nav">
<ul>
<li>Page Top</li>
<li>Watch the Video</li>
<li>Kickstarter</li>
<li>About the Project</li>
<li>Meet the Team</li>
<li>What Are We Doing?</li>

The problem is that your javascript drastically changes the default link behavior inside of the single-page-nav container. It is applying this javascript functionality to your external links as well, which you do NOT want to have in order for them to work properly.
This bit e.preventDefault(); in your javascript prevents the browser from handling the click event normally.
To fix your problem I would apply the class single-page-nav to the ul (since your social links are outside of this ul) and tweak your CSS a bit.
Personally, I would change the CSS something like so:
.topnav { ... }
.single-page-nav { ... }
.single-page-nav li { ... }
.topnav a { ... }
.topnav a:hover, .topnav .current { ... }
