JQuery :: Generate A Dynamically Sized Grid For Drag And Drop?
Jun 21, 2010
I've never worked with Ajax before but I've been reading up on it and done some basic tutorials and am comfortable with the concept of asynchronous communication and how everything works from a technical communication perspective. That being said I have no idea where to start on this project which seems like it should be fairly simple. 1. the browser will have a "working area" which is a rectangle of some decent size, there will be a toolbar of objects on the left hand side. This work area should be shown as a grid that the objects will be placed into.The size of this grid (basically the gridlines) will need to be generated automatically based on user input (also the size of the components/objects that will be dragged in and the size of the rectangle) if it is too large (say 500) i'd like a way to pan around and zoom in as well... 2. For simplicity say there are 2 components: Available, unavailable and an erase feature. 3. each object when dragged to the working area should create an object that has some properties (handled programatically from input elsewhere on a simple form) I will be placing these in a database server side. 4. I'd like to be able to drag across the grid to continuously add the selected object and I'd like to be able to click a button on the edge of the grid to fill in the entire row with the objects. From everything I've read on this it seems like this should be somewhat easy but again I don't know what framework to use to start. I'll be putting this in a drupal site and integrating it with a few modules if that makes a difference (i think that part of the programming will be separate from whatever specific implementation I use to get this Ajax part up though)
What I am looking for is to have a database hold a list of images ( or numbers that correspond to images)... that should be easy enough. The part I am having trouble with is having these images aligned in a grid which is inside a window /frame/ box on the web page. The user can click and drag and it will move around this collection of images.....
Like so (numbers represent images): 5 4 3 6 1 2 7 8 9 So if the user clicked and dragged to the right the images would then look like: 4 3 12 1 2 11 8 9 10 The new images are taken from the database and the user can drag in any direction.
Everybody knows how a dropdown menu works where a person clicks on the drop down menu and it displays a drop down list where the user can select an option from the list. What I want to know is that is there a way in html where except displaying a dropdown list can I display a grid instead with the options in the grid?
This link will show you how I want it to be dislayed like but I do not know how this is done.
I am not new to jQuery but I just want to ask the best way to approach this. Basically I have a textfield in which the user is going to type in a number (for example 20) and after this textfield lose focus jQuery will be triggered to create whatever number of textfields the user put before (in this case 20).
So, to illustrate: How many users do you have: [ 2 ](and after the field above lose focus, the below will be generated)
I have a question for flexigrid jquery grid control users.
I am able to display json data returned from my WCF service in my Flexigrid in my application.
The paging toolbar displays correctly and it's clear that the paging toolbar understands how I've configured it.
However, the grid is not actually implementing the paging filter on the data in the grid. For example, the paging toolbar says "Displaying 1 to 10 of 12 items". However, all 12 items are displayed in the grid.
I guess I'm missing a config setting or callback. Any idea what the problem might be?
Im having the exact same problem as posted here:[URL]
When I drag my link to my droppable area, an ajax request is supposed to triggred, but it seems like the whole page is beeing reloaded. This works fine with Chrome and Firefox. It works in IE if I have insert an alert in the drop function.
Im including the drop code I have:
$('.droppable').droppable({ drop: function(ev, ui) { var intSourceObjectType = ui.draggable.attr('objecttype'); var intSourceObjectId = ui.draggable.attr('objectid');
Please the link to see what I have done so far...[URL]... It is a day planner, where various places can be dragged on to the day planner. It works, but it seems very slow. Running firebug profile when dragging a simle place into a single slot tells me that over 35,000 calls were made.
I've got a page that uses the draggable and droppable feature - [URL]
It also uses jQuery to call a web service via Ajax - this also works fine.
However, I want to call the web service only when an item is dropped onto the objeect but when I try to add the Ajax function inside the $("#droppable").droppable({ drop: function(event, ui) {.... it doesn't seem to work.
I am using jQuery Tabs to make an ajax call for each tab when clicked. The ajax that displays is like inettuts. 3 or 4 columns of widgets that can be dragged and dropped. The problem that I am having, when I put the html of the result directly in the main page, it works as designed. When I click on a tab, it displays the page, but all the jquery functions in that ajax page are gone and I cannot sort, drag and drop anything. I suspect that the ajax page is not reading the javascripts in the head, which are on main page. Unfortunately I can't remove them to include them in ajax pages dynamically because I am also using them for other functions in main page. Is there a way to make those ajax pages read the javascripts on that main page?
I found fantastic drag and drop technique, analyzied javascript file and would like to get helo, how to create it. Here: [URL] you can drag and drop the photos to the right box, then you can email them. How can I create it on my own website? You can find javascript file here: [URL]. Is it possible at all?
I'm finally getting around to try the drag and drop functionality of jquery. I am working with the Shopping Cart example. Everything is working great but I would like to add a remove link to the dropped item so it can be deleted from the shopping cart.
Needless to say I haven't even gotten to the code to actually remove the link cause I can't even append the link...haha
This results in nothing: $('<a href="#">remove</a>').after(ui.item);
This results in duplicate entry of the dragged element with the bullet point: $('<a href="#">remove</a>').after.ui.item;
I am trying to use jquery drag and drop in cfwindow it does not work when i place code out side cfwindow it works nicely, how can i resolve this issue, i tried usinf cfajaxonload but no luck.
I am working on a project where I need to drag an image from a ASP.NET datalist control that is bound to a datatable to a repeater control that is bound to a datatable. The issue I am having is I need to know the Id (field bound to the datalist) of the row of the dragged image. Is there a way to access this field when the image is dropped? I would also need to know the id of the row in the repeater that the image is dropped on.Here is the code that I currently have:
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="SRCartPg2.aspx.cs" Inherits="HRI.Proof"%> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" >[code]............
I am attempting to build a page, however using some sample code the page have drag and drop functionality.
After using a simple jqeury statement to add to this form, every thing working (drag and drop)properly.
Now my actual requirement is
I need to generate the controls dynamically. Whne I generated all controls from server side and put all the generated controls HTML snipet in
< div id ="sort1" class ="groupWrapper">
its working fine but when I try to put same HTML snippet in the same DIV using JavaScript drag and drop functionality not working;
Below is the code I am using.
Case when drag and drop functionality Not working.
<! DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> < html xmlns="http://www.w3.org/1999/xhtml">
I'm looking to find out a way to drag and drop table rows between two tables. I reused jQuery example for portlets, but that did not work to full satisfaction. In above screen shot I added border, but that is just for illustration of the issue. Problems:As you will see from the code I have to work with relative measurement there for I use percentage. I wasn't able to enforce row width to fill in whole table. How do I force full row width?
Drag-able row are part of table body (tbody) and headers are done with thead. In this scenario I enforced same style settings on header as body and everything is now squashed to the left. If I leave styling out of header then first header stretches over whole tdody content and second is out of place over nothing. Sort of bad designed table when you forget one column. This become a big issue if there is more then 2 items in a row, for example 4 column in tbody get squashed under one thead column even though there are 4 headers to align under it.
I have a problem with the drag and drop function. I would like to drag a div and when I drop it I want a copy of the div to append to the area and I want to be able to do the same process over and over again. Example: [URL]. I want my div to behave the same way but without the "sortable" function, instead I want to put the div wherever I want. I have tried to do just that for several days, without success.
Im working on some drag and drop logic similar to the jQuery shopping cart example, but I've run into a small hitch. If I double click on the LI within my 'dropped' area it causes them to become draggable again. I specifically set up drag to only work from one source list, so Im unsure how double clicking is causing this bug?
IE7 & IE8 refuse to run this code that must reposition a crosshairs over a street map. The crosshairs can be dragged and dropped only once. The second time I attempt to drag the crosshairs, nothing moves but this message appears: "object doesn't support this property or method" on the sentence posx = pos.left; By the way, the class crosshairs has position:relative.
Any plugin/website that is jQuery, which will do what this Dojo example does, i.e: [URL]. I am wanting something similar to this as I would like to use as a means of allowing a user to administer a menu structure.
