JavaScript - Drag & Drop Images (highlight Or Focus Problem)
Firstly, I'm not trying to 'fix' the code below. (eg: not interested in links to other drag & drop scripts).
I'm mearly trying to understand what's happening & what I've missed or done wrong. For instance, why in FF & IE does it wait until after onmouseup (release) before moving the object, because it works fine with a DIV with only text in it, but not with a DIV with an image in it, or a stand alone image. In Chrome it seems to highlight the image and onmousemove also highlights the surrounding areas. I've tried forcing focus() & blur() & covering with a higher zIndexed transparent DIV but nothing seems to work. Any help in understanding would be greatly appreciated. dragscript.js Code:
document.onmousemove = mouseXY;
document.onmousedown = mouseDown;
document.onmouseup = mouseUp;
var mouseX = 0;
var mouseY = 0;
var drag;
var dragObject = null;
var mouseOffsetX;
var mouseOffsetY;
function mouseXY(e) {
e = e || window.event;
if (e.pageX || e.pageY) {
mouseX = e.pageX; mouseY = e.pageY;
}
else if (e.clientX || e.clientY) {
mouseX = e.clientX + document.body.scrollLeft + document.documentElement.scrollLeft;
mouseY = e.clientY + document.body.scrollTop + document.documentElement.scrollTop;
}
document.getElementById('mouseposX').value = mouseX;
document.getElementById('mouseposY').value = mouseY;
if (dragObject) {
document.getElementById(dragObject.id).style.left = mouseX - mouseOffsetX;
document.getElementById(dragObject.id).style.top = mouseY - mouseOffsetY;
}
}
function mouseDown(x) {
if (!x) var x = window.event;
if (x.target) drag = x.target;
else if (x.srcElement) drag = x.srcElement;
if (drag.nodeType == 3) drag = drag.parentNode;
if (drag.className == 'dragable') {
dragObject = drag;
document.getElementById('ObjectId').value = dragObject.id;
mouseOffsetX = mouseX - document.getElementById(dragObject.id).offsetLeft;
mouseOffsetY = mouseY - document.getElementById(dragObject.id).offsetTop;
}
}
function mouseUp() {
dragObject = null;
document.getElementById('ObjectId').value = '';
}

Many thanks, Paul PS: Login for posting timeout too short. Similar TutorialsAll, I'm trying to create a calendar application that users can upload pictures and then put them on a calendar. I'd like to display all of the images and then drag them from one pane to the calendar. I'd like it to be something similar to the following link: http://www.vistaprint.com/studio/cal...id=button&rd=2 Does anyone have any scripts that can do the drag and drop or could you possibly give me an idea on where to start with something like this? I really appreciate the help in advance! Thanks! I am having a problem sending info to a database. I have set up drag and drop with HTML5 and it is working, but I need to be able to get the values of the images uploaded to the database when each one is dropped into a dropzone. I don't need to upload the images to the database - just need the value of each image sent to it. Here is the HTML: Code: <ul id="images"> <li><a id="1" draggable="true"><img src="images/1.jpg" value = "flower"></a></li> <li><a id="2" draggable="true"><img src="images/2.jpg" value = "boy"></a></li> <li><a id="3" draggable="true"><img src="images/3.jpg" value = "girl"></a></li> </ul> <form name = "objects" id="form" action = "form.php" method = "post"> <div class="drop_zones"> <div class="drop_zone" id="drop_zone1" droppable="true" type = "text" name = "drop_zone1"> </div> <div class="drop_zone" id="drop_zone2" droppable="true" type = "text" name = "drop_zone2"> </div> <div class="drop_zone" id="drop_zone3" droppable="true" type = "text" type = "file" name = "drop_zone3"> </div> </div> and the javascript Code: var addEvent = (function () {
if (document.addEventListener) {
return function (el, type, fn) {
if (el && el.nodeName || el === window) {
el.addEventListener(type, fn, false);
} else if (el && el.length) {
for (var i = 0; i < el.length; i++) {
addEvent(el[i], type, fn);
}
}
};
} else {
return function (el, type, fn) {
if (el && el.nodeName || el === window) {
el.attachEvent('on' + type, function () { return fn.call(el, window.event); });
} else if (el && el.length) {
for (var i = 0; i < el.length; i++) {
addEvent(el[i], type, fn);
}
}
};
}
})();
var dragItems;
updateDataTransfer();
var dropAreas = document.querySelectorAll('[droppable=true]');
function cancel(e) {
if (e.preventDefault) {
e.preventDefault();
}
return false;
}
function updateDataTransfer() {
dragItems = document.querySelectorAll('[draggable=true]');
for (var i = 0; i < dragItems.length; i++) {
addEvent(dragItems[i], 'dragstart', function (event) {
event.dataTransfer.setData('obj_id', this.id);
return false;
});
}
}
addEvent(dropAreas, 'dragover', function (event) {
if (event.preventDefault) event.preventDefault();
this.style.borderColor = "#000";
return false;
});
addEvent(dropAreas, 'dragleave', function (event) {
if (event.preventDefault) event.preventDefault();
this.style.borderColor = "#ccc";
return false;
});
addEvent(dropAreas, 'dragenter', cancel);
// drop event handler
addEvent(dropAreas, 'drop', function (event) {
if (event.preventDefault) event.preventDefault();
// get dropped object
var iObj = event.dataTransfer.getData('obj_id');
var oldObj = document.getElementById(iObj);
// get its image src
var oldSrc = oldObj.childNodes[0].src;
oldObj.className += 'hidden';
var oldThis = this;
setTimeout(function() {
oldObj.parentNode.removeChild(oldObj); // remove object from DOM
// add similar object in another place
oldThis.innerHTML += '<a id="'+iObj+'" draggable="true"><img src="'+oldSrc+'" /> </a>';
// and update event handlers
updateDataTransfer();
// little customization
oldThis.style.borderColor = "#ccc";
}, 500);
return false;
});
and the php PHP Code: <?php $sql="INSERT INTO table_answers (drop_zone1, drop_zone2, drop_zone3) VALUES ('$_POST[drop_zone1]','$_POST[drop_zone2]','$_POST[drop_zone3]')"; if (!mysql_query($sql,$db)) { die('Error: ' . mysql_error()); } echo $_POST["drop_zone1"]; echo $_POST["drop_zone2"]; echo $_POST["drop_zone3"]; ?> There is no error, it is not registering that there is something in the dropzone - nothing is being sent through the php. I have tried doing it with just text(instead of the image) and that won't work either. I am unsure of how to target the value of each image through javascript/php. Please help if you can, Thanks Hi I need a help with my code. When i'm trying to put a picture in empty div it works fine, but when i put the second picture to the div where already is picture, then second picture "disappear". If i have only one div, then everything is ok, but with 2 or more divs i have issue. PHP Code: <div id="drop" ondrop="drop(event)" ondragover="allowDrop(event)"></div> <div id="drop2" ondrop="drop(event)" ondragover="allowDrop(event)"></div> <img id="drag1" src="http://images.photo.bikestats.eu/zdjecie,600,79346,20091201,zdjecia-wiewiorek.jpg" draggable="true" ondragstart="drag(event)" width="80" height="80"> <img id="drag2" src="http://www.tech-blog.pl/wordpress/wp-content/uploads/2011/12/gaba-16-12-2011.jpg" draggable="true" ondragstart="drag(event)" width="80" height="80"> <style> #drop { border: 1px solid black; width:80px; height:80px; } #drop2 { border: 1px solid black; width:80px; height:80px; } </style> <script> function allowDrop(ev) { ev.preventDefault(); } function drag(ev) { ev.dataTransfer.setData("text/html", ev.target.id); } function drop(ev) { ev.preventDefault(); var data = ev.dataTransfer.getData("text/html"); var parent = ev.target.parentNode; if( parent.id == 'drop' ) { parent.removeChild(ev.target); parent.appendChild(document.getElementById(data)); } else ev.target.appendChild(document.getElementById(data)); } </script> Hi everyone I am having a bit of trouble with a question that I have been given for my Javascript assignment. I was given a web page with a series of boxes (created by <div> tags) which could be dragged and dropped anywhere on the web page, and they were dragged by holding the mouse down and dragging, and released when the mouse button was released. The web page can be viewed at http://adamr.hitwebs.net/dragDropOriginal.html and the source can be viewed at http://adamr.hitwebs.net/dragDropOriginal.js. The assignment was to make any other element drag-and-droppable, so I chose to make a jigsaw puzzle and hence make images drag-and-droppable, but with minimal changes to the script (simply changing the class name and id of my images), the dragging and dropping process is visually very different (the images appear to "stick" to the cursor on mouse up, and you have to actually click a second time to drop the image). Can someone please help me to fix this so that the drag and drop looks like what the boxes did (an example of what I want is exactly how the smiley faces are dragged-and-dropped at http://elouai.com/javascript-drag-and-drop.php). My jigsaw puzzle can be viewed at http://adamr.hitwebs.net/drag&Drop.html and the source can be downloaded from http://adamr.hitwebs.net/dragDrop.js. As you will see, apart from the large sections of script that I added, I only changed about two or three words of the original script, and it stopped working properly as soon as I started using images, which was long before I made my own additions to the script. Also note that there are A LOT of comments in my code because this is an assignment, and I have to note every change that I made to the original code, as well as put explanatory comments in my own code. P.S. Please don't tell me to use the script on the smiley face web page that I have provided, as this would not be useful to me. I must amend the script that I was originally given with the boxes. As for the assignment, I have checked this with the teacher, and I will not lose any marks for the terrible drag-and-drop effect as it does not appear to be my fault. This post is purely for my curiosity and because I hate not being able to solve a problem, and to me, this is a problem. Thanks heaps, - Adam Hello everyone! So, what it does: You can successfully drag something anywhere, but when you click it again, it resets to its original position (I don't know why), and when you try to drag it again, as soon as your cursor touches the object it disappears (I don't know why). I'm hoping someone can tell me why it is happening and how to fix it! Code: // JavaScript Document
var posX;
var posY;
var element;
function drag(event) {
element = document.getElementById("square");
posX = event.clientX;
posY = event.clientY;
element.addEventListener("mousemove", move, false);
}
function move(event) {
if (typeof(document.getElementById("square").mouseup) == "undefined")
element.addEventListener("mouseup", drop, false);
//Prevents redundantly adding the same event handler repeatedly
element.style.left = event.clientX - posX + "px";
element.style.top = event.clientY - posY + "px";
}
function drop() {
element.removeEventListener("mousemove", move, false);
element.removeEventListener("mouseup", drop, false);
}
the html is a simple (position is set to relative): <p id="square" onmousedown="drag(event)">meep</p> Lastly, and most importantly, thank you all for your time =] EDIT: This is the first time I've written javascript code and would like to learn the basics, which is why I am not using a library. Hello, I'm in need of help on my drag and drop code. How can I make 2 images (1 draggable, 1 static) each switch to alternate images when the draggable is dragged over the static?
Hey complete beginner to javascript here so sorry if I'm doing something stupid Basically I've tried to follow this guide to make it so that I can move an image on the page. I have a style tag in the head Code: <style type="text/css">.drag{position: relative;}</style>
I have an image like this: Code: <img src="logo.png" class="drag" alt="logo" /> which is obviously in the body I copied and pasted the code given in the guide: Code: <script language="JavaScript" type="text/javascript">

I have tried putting the javascript in the head and the body but no matter where I put it, I can't drag and drop the image. What am I doing wrong? Thank you for your time All I Want To Make Happen Is That If You Drag and Drop A Div Into A Table An Action Happens

Dear forum Rather than use a library, I have attempted to write my own attempt at a script that allows multiple elements to be dragged around the page. It starts by loading all divs into an array, and then forms a new array of only divs with the required class name. I believe this script doesn't work for internet explorer, but I am not concerned by this. As you will see if you run the code below, the script works well for divs containing text, but if I include an image inside a div, then the image will follow the mouse even if the button is released. I have spent a whole day on this tiny script and really don't know where to go from here! Could anybody shed some light on this please? Thanks Matt Code: <html>

Hi Folks, I've been trying to create a drag drop homepage like www.bbc.co.uk, google etc. I can get the basic drag and drop to work, but I can't get the layout to save anywhere. Can anyone please help? Here is what I have so far. http://www.sandwell.nhs.uk/test/test.html It uses Glow, which doesn't have any cookie functions apparantly.

Hi, I am currently working in mail client project. The mails are displayed in the html table. I have an requirement to drag and drop the mails from the Inbox to another folder. Can you please suggest how to proceed with this. Thanks in advance. Regards, Anne. Hi, I have the following code for drag and drop objects in any page. My target: I want to be able to drag and drop the advertisement images that come on top of the page. It works most of the time, but sometime page crashes. I use google chrome as a bookmarklet. Code: Code: javascript:var d=document,b=d.body,i="innerHTML",s="style",p="position",a="absolute",r="relative",w1="offsetWidth",w2="width",h1="offsetHeight",h2="height",t1="offsetTop",t2="top",l1="offsetLeft",l2="left",drag=false;function down(e){drag=true;z=event.srcElement;z[s][p]=r;x=event.clientX;y=event.clientY;zx=z[l1];zy=z[t1];d.onmousemove=move}function up(e){drag=false;}function move(e){if(drag){z[s][l2]=zx+event.clientX-x;z[s][t2]=zy+event.clientY-y}}document.onmousedown=down;document.onmouseup=up;
Any improvements in the code is appreciated. Does anybody have a advanced better code, because I am just medium in javascript. I'm sure that you must be sick and tired of the drag & drop question and for that I apologise but I have not been able to find an answer to this particular requirement despite much reading. The object of this task is to create a very limited editor in javascript. I have a page with two DIVs in columns. The left DIV holds text and the right holds several images. The DIVs are populated as the page loads. There are a couple of buttons used to apply styles to the selected text, heading or description. Looking like this :- Code: <div id="details"> <p class="heading">text</p> <p class="desc">text</p> <p class="heading">text</p> <p class="desc">text</p> <p class="heading">text</p> <p class="desc">text</p> </div> Once the text has been formatted as above, I want to be able to drag the images into place in the text like this :- Code: <div id="details"> <p class="heading">text</p> <p class="desc">text</p> <p class="heading"><img src="photo.jpg">text</p> <p class="desc">text</p> <p class="heading">text</p> <p class="desc">text</p> </div> The images in the left DIV have been given float right in css. I have not been able to find a method of placing that image in position like that. I guess it doesn't have to be drag&drop, but that would be far easer for the operator. Can anyone point me in the right direction please but I beg, please be gentle I am a newbie at javascript. Many thanks. Edited to add: This only needs to work in FF. I am trying to loop through each area and checking if they match the image class number then it should drop in correct place. You can see that i commented out the loop and if statement because it doesn't work. Can anyone shine light on this because i'm frustrated with this issue. Code: $(document).ready(function(){
var images = $('#clothes').find('img');
var drop = $('#dress').find('area');
for(var a=0; a < images.length; a++){
$( images[a] ).draggable( );
//alert($(images[i]).hasClass("20"));
if($(images[a]).hasClass("20")){
$( images[a] ).draggable({ revert: 'valid' });
//alert("WRONG");
}
else{
$( images[a] ).draggable({ revert: 'invalid' });
}
/*for(var b=0; b < drop.length; b++){
$( drop[k]).droppable({
activeClass: "ui-state-hover",
hoverClass: "ui-state-active",
drop: function( event, ui ) {
$( this ).addClass( "ui-state-highlight" )
/*if($(images[a]).attr('class').split(" ")[0] == $(drop[b]).attr('class')){
alert("RIGHT");
$(images[a]).draggable({ revert: 'invalid' });
}
else if($(images[a]).hasClass("20")){
$( images[a] ).draggable({ revert: 'valid' });
}
//alert("a = " + $(images[a]).attr('class').split(" ")[0] + " b = " + $(drop[b]).attr('class'));
}
});
}*/
}
});
Hi all, I'm currently developing a drag on drag editor at work. I have a list of fields on the right which I drag onto a form and it adds the input object onto the form. I also have editable divs which I using to add text as a kind of very scaled down RTE. Rather than dragging a field the form, I could use the field as display only so I would like to embed this into the editable div as part the text. I'm thinking I could do something like facebook does where if I type a "@" then I could create a auto suggest to embed a field value into text but what i would like to do is drag the field into the text. So my question is this, is it possible to know the positon in the text of where I performed the drop, I suppose that would be where the mouseup occurs? Any thoughts much appericated, Thanks, Dale Hello CodingForums! I need some help with drag & drop links / downloads. I would like an example like the following website; http://panic.com/ |
