JavaScript - Drag - Not Catching My Mouse Events
Hi!
Just registered, because I'm trying to figure out some dragging stuff and it's not working the way I'd like and I really can't figure out why. I made a drag element (image). I just want to apply the code to this element. This is what happens: 1. I click on the image 2. I hold the mouse down and drag => the element don't follow 3. I let go of the mouse button => the element gets dragged 4. I click again => the element stops dragging This is what I would like to happen (obviously): 1. I click the image 2. Hold the mouse down and drag => element follows 3. Mouse up => element stops following Code: var dragSko;
var dragSkoUrsp;
document.onmousedown = startaKod;
document.onmouseup = musUpp;
function startaKod(e) {
if (e.target.id == 'dragsko') {
startX = e.clientX;
dragSkoUrsp = parseInt(e.target.style.left);
document.onmousemove = musFlyttDrag;
dragSko = e.target
}
function musFlyttDrag(e) {
dragsko.style.left = (dragSkoUrsp + e.clientX - startX) + 'px' ;
}
}
function musUpp(e) {
document.onmousemove = null;
}
I'd very much appriciate if some kind soul had a look and explained what I've done wrong. Similar TutorialsHi I have a requirement....I have a timer on a page. If the user leave the page (mouse goes off of that page) the timer starts and continues...and when the user comes into that page(mouse over that page) the timer goes off/STOP....Is this can be done?? using javascript??? pls help... can any one say me how to resize a div by mouse dragging in javascript........ ..first of all is it possible or not?? and if so , what should i do...... Is it possible to trigger mouse events with shapes drawn in an HTML5 canvas? I want to create a page with drawn elements that you can mouseover and pop up a dialogue box. I also want the shapes to react with some type of feedback. I'm hoping I can do this with javascript instead of Flash but haven't found a way to do it that's simple enough to make it worth it.
Hi, I am new here, I am trying to find solution for one problem with my new web page, I want to use amazing effect -by mouse draging or swipe on the certain image which should launch animation effect (something like image rotating) -set of images should run dynamicaly and so simulate fluid effect (movie). For a better Idea what I need it can be for example something as physical lever switch with spring when this switch is slightly tilted spring complete this action and switch is flipped to other state. Or another example image of book should be on web and when someone drag and pull page this should independently continue and complete action - turn to new page. So my question .. is something like that possible with javascript if yes can You please point me where I have look or how this can be done, each advice will be valuable for me or maybe javascript isnt right choice for this can You advise me? THANKS Example of my problem: HERE The code is derived from a site offering some advice for javascript: HERE The example of mine tries to use an image as hyperlink... and use mouse events for certain actions. Aside from possibly being the worst javascript code humanly possible...once I slaughtered the code from the site mentioned above, I'm not getting how to arrange things so that a mouse over event switches an image , as does mousedn and mouseup, And (and this is the rub for me) repeating the setup in the same way for a list of quicktime video links. I've got it to work for one row in the table I'm using to attempt some kind of formatting. I'm told `css' is a better way for that but I'm completely ignorant about how to use `css'. So, for now I'm using a table to get at the javascript question. The idea is for viewer to see three red dots at the front of each item being offered. Mouseover is supposed to switch to a green arrow... mousedn is supposed to switch to 2 check marks. I wanted the check marks to persist, so for lack of knowing how to accomplish that... I let mouseup call the same image. (the check marks; Maybe just omitting any directive for mouseup would have the same effect?) About the `image persisting after being clicked' question: It is really a separate question so I will probably start a different thread for that. What I've done works for one list item... but fails for more than one. The only active member of the list (2 in my example) is the bottom one. mouse events on the top one are carried out on the bottom one. I tried to just change the name of all variables in the javascript, and the name given in the `img src=' section of the html code, for the second row... but clearly not what is needed. I changed the names shown below by incrementing the number in the names by 1. I've only posted one row's worth but the next row uses the same code with the variables incremented. And hopefully someone will look at the actual example (URL given above) and see the full code. The basic code I've put here for convience.: Code: <table>
<tr>
<td valign=top >
<A href="./t2.html" onMouseOver="return changeImage()" onMouseOut= "return changeImageBack()"
onMouseDown="return handleMDown()" onMouseUp="return handleMUp()"

Hi, I am trying to fire a mouse event in IE at a particular coordinate. All the coordinates are set right before firing the event. But when the event gets fired, the client point gets changed and gets the value same as offset point. i.e., I created a mouse event with ClientPoint = (583,438) , offset= (585,481) and screen = (585,589). The event when it gets fired from the browser however has the client point as (585,481) - the rest are fine though. Can someone tell me how can I reliably fire a mouse event at a particular client point in IE? TIA srd I'm trying to enable/disable a textarea. I am able to do a mouseout disable, but cannot do a mouseover enable. For instance, when I click on the image, a textarea shows up. When I move my mouse to a different location, the textarea disables fine. Then when I try to move my mouse back over the textarea, it DOES NOT enable for me to write in it. What am I doing wrong? Thanks! Another bonus question, I just happen to try out this code in IE and the textareas are not showing up where I click. I assume that I'm capturing the X/Y coordinates incorrectly for an IE browser. Any pointers? ********* CODE ************* <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <title>Mouse position</title> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"> <script type="text/javascript"> var posx, posy; // initialize cache var cache= []; var count=0; function getMouse(e){ posx= posy= 0; var ev= (!e) ? window.event : e;//IE:Moz if (ev.pageX){//Moz posx=ev.pageX+window.pageXOffset; posy=ev.pageY+window.pageYOffset; } else if(ev.clientX) {//IE posx=ev.clientX+document.body.scrollLeft; posy=ev.clientY+document.body.scrollTop; } else { // old browsers return false; } } function showP(){ // object to store this coordinate var thisCoord= {}; // x & y values stored as object attributes thisCoord.posx= posx; thisCoord.posy= posy; // check the cache for this coordinate object if ( !cache[thisCoord] ) { // if it hasn't been cached yet, push it onto the stack cache.push(thisCoord); var newDiv= document.createElement("textarea"); newDiv.setAttribute("class","div3"); newDiv.setAttribute("id",count); newDiv.style.width='180px'; newDiv.style.height='45px'; newDiv.style.visibility="visible"; newDiv.style.top= (thisCoord.posy -10) +'px'; newDiv.style.left= (thisCoord.posx -6) +'px'; newDiv.setAttribute("onmouseout","this.disabled=true"); newDiv.setAttribute("onmouseover","this.disabled=false"); // append to the document BODY document.getElementsByTagName("body")[0].appendChild(newDiv); count++; } } </script> <style type="text/css"> .div1 {position:absolute;top:100px;left:100px;visibility:visible;z-index:5} .div2 {position:absolute;top:0px;left:0px;visibility:hidden;z-index:1;color:black;} .div3 {position:absolute;visibility:hidden;z-index:10;font-size:14px;font-weight:450;color:black;} textarea[disabled='disabled'] { background:yellow; color:blue; cursor:default; } </style> </head> <body> <div id="div1" class="div1"> <img id="theImage" src="./YourImage.jpg"> </div> <script type="text/javascript"> // setup event handlers // document BODY onmousemove document.getElementsByTagName("body")[0].onmousemove= function(e){ getMouse(e); }; // the image onclick document.getElementById("theImage").onclick= showP; //onMouseOut </script> </body> </html> I am using a freebie script that changes css elements using onClick when you hit a button. I have 12 choices I want to add, and don't want 12 buttons, but rather a dropdown list. 2 button examples (and js code) is: <input onclick="changecss('li','background','url(images/list_02.jpg) no-repeat 10.2em .12em')" value="Change to BG 2" type="button" /> <input onclick="changecss('li','background','url(images/list_03.jpg) no-repeat 10.2em .12em')" value="Change to BG 3" type="button" /> How do I convert this to a SELECT list?? Thank you! I've got to have a typo somewhere, but i can't seem to find it. I need a new pair of eyes to point it out for me. background: trying to code a mouseover link for a nav bar. everything is working( hyperlink, normal image shows up) but when i mouse over the image swap doesn't happen. I have 2 parts of code. 1st preloads images and does the swap function. loads in <head> See below: Code: <SCRIPT language="javascript" type="text/javascript">
if (document.images)
{
/* preload images */
var subcontractorsOn = new Image ();
subcontractorsOn.scr = "subcontractorsOn.gif";
var subcontractorsOff = new Image ();
subcontractorsOff.scr = "subcontractorsOff.gif";
}
function mouseOn (imgName)
{
if (document.images)
document [imgName].scr = eval (imgName + "On.scr");
}
function mouseOff (imgName)
{
if (document.images)
document [imgName].scr = eval (imgName + "Off.scr");
}
</SCRIPT>
2nd just calls the functions to preform the swap. this is in the <body> see code below Code:
<a href="subcontractors.htm" onMouseOut="mouseOn('subcontractors')"
onMouseOver="mouseOff('subcontractors')">
<img src="subcontractorsOff.gif" height="40" width="133" name="subcontractors" id="subcontractors" border="0" alt="subcontractors"></a>
any insight would be great. regards, Fatmann66 Hi, It would be easier to explain this if you play mafia wars (or any game that includes intra-game exchange of gifts/items between members) but the actual scripting doesn't require any knowledge of the game. Background Information Mafia Wars is a game on Facebook (and myspace, yahoo etc.) that among other things allows its players to send gifts to each other. Now because different people end up with more things of one type and are short of things of another type, the players have evolved a trading dynamic. Where x number of Item 1 is traded for y number of Item 2. A simple marketplace. And with this territory come scammers. Essentially a player who doesn't go through with his end of the deal. good player sends item to bad player. bad player removes good player from mafia and blocks him for ever contacting him through his facebook profile. This has given rise to my group, among many others, that lists these scammers (identified with their facebook profile ids) as they are reported every day. Now over time the list has grown and it has become difficult and unrealistic to expect people to know who is on the list and who is not. The Requirement A javascript bookmarklet (there are many already servicing different needs of the players) that sits on the browser and tells the user if the person he is about to trade with is a listed scammer or not. The Breakdown The user will click the bookmarklet when he is on the facebook profile of the person he is about to trade with. When clicked the script will pull the facebook profile id from the current page, and then scan a text file located on a third-party server and return with a pop-up box message that reports if the id is listed as a scammer or not. It should be pretty simple to do, except I don't know the first thing about javascript coding. So if there's anyone who can devote a few hours/days to help us out with this it would be greatly appreciated. Thank you.

Trying to get a pop-up div to be draggable, but it doesn't seem to be working. Can someone help me out? I'd be very grateful! JavaScript I'm using: Code: //used for dragging div
function agent(v)
{
return(Math.max(navigator.userAgent.toLowerCase().indexOf(v),0));
}
function xy(e,v)
{
return(v?(agent('msie')?event.clientY+document.body.scrollTop:e.pageY):(agent('msie')?event.clientX+document.body.scrollTop:e.pageX));
}
function dragOBJ(d,e)
{
function drag(e)
{
if(!stop)
{
d.style.top=(tX=xy(e,1)+oY-eY+'px');
d.style.left=(tY=xy(e)+oX-eX+'px');
}
}
var oX=parseInt(d.style.left),oY=parseInt(d.style.top),eX=xy(e),eY=xy(e,1),tX,tY,stop;
document.onmousemove=drag;
document.onmouseup=function()
{
stop=1;
document.onmousemove='';
document.onmouseup='';
};
}
//used for pop-up div
function pop(div)
{
document.getElementById(div).style.display='block';
return false
}
function hide(div)
{
document.getElementById(div).style.display='none';
return false
}
Also, here is the HTML: Code: <a href="#" onclick="return pop('myDiv2')">Pop-up div #2</a> - Hidden div shows upon clicking this link, but it won't drag
<div class="bubble" onmousedown="dragOBJ(this,event); return false;">
<div id="myDiv2" class="parentDisable">
Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.
<p><a href="#" onClick="return hide('myDiv2')">Close [X]</a></p>
</div>
</div>
And the CSS: Code:
.parentDisable {
position:absolute;
margin:120px;
padding:20px;
width:400px;
display:none;
z-index:3;
background-color:#DEDEDE;
border:1px solid #DEDEDE;
border-radius:5px; -moz-border-radius:5px; -webkit-border-radius:5px;
}
.bubble { position:fixed; width:400px; top:150px; left:250px; cursor:move; }
All I Want To Make Happen Is That If You Drag and Drop A Div Into A Table An Action Happens
hi, i want to drag the div which have a image in it: but i find that if i click on the image, i cannot drag the div, (in FF3.5) any advice would be appreciated. Code: <div id="div1"> <imc src="XXX.jpg"> </div> and i have a JS something like that...: Code: drag();
function drag(){
document.onmousedown = startdrag;
document.onmouseup = enddrag;
}

dragobj=e.target;
alert(dragobj.id);
}

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">

var _debug = $('debug'); // makes life easier
InitDragDrop();
function InitDragDrop()
{
document.onmousedown = OnMouseDown;
document.onmouseup = OnMouseUp;
}
function OnMouseDown(e)
{
// IE is retarded and doesn't pass the event object
if (e == null)
e = window.event;

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 Hei, I should start by saying that I am very new in Javascript.. what I need to do is to drag the entire window...any ideas how to do that ? Thanks 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?
There seems to be a lot out there, but I haven't found a javascript for a click and drag that has been bug free. Does anyone have any suggestions? The last one I had didn't work in Safari.
