  • Best Practices & Considerations when writing HTML Emails

    - by Jonathan Sampson
    I've been developing websites for over a decade now, but quickly found that many of my habits in developing for the web are useless when developing for email clients. This has caused me an enormous amount of frustration, so I thought I would ask a question that would hopefully surface the best practices and necessary considerations for others like myself who may find themselves designing for gmail, outlook, etc. from time to time. Example: <style>...</style> vs inline CSS. In short: what transfers over from the web-world to the email-world, and what doesn't.

  • Create collage with multiple images

    - by Andres
    I'm having quite a challenge... I have a web page where the user clicks on images, those images have to be added together to create only one image and the user must be able to download that group of images as only one... I have no idea how to do this, any tip or info so I can start researching? Here is an example I found searching with google: In my case each of the squares of the image would be a totally different image but this Is what I have to achieve... Thanks!

  • Json problem with Page Method call on IE 8.

    - by ProfK
    I have the following code that populates a select element with values from an ajax call, via a Page Method. In FF, the code works perfectly, in IE8 I get the error: 'ResourceList[...].id' is null or not an object. What can I look at here? function readShift(jsonString) { var shiftInfo = Sys.Serialization.JavaScriptSerializer.deserialize(jsonString); var listItems = ""; listItems += "<option value='0'>[Unassigned]</option>"; for (var i = 0; i < shiftInfo.ResourceList.length; i++) { listItems += "<option value='" + shiftInfo.ResourceList[i].id + "'>" + shiftInfo.ResourceList[i].name + "</option>"; } $("#" + resourceListId).html(listItems); };

  • Multiple Post Requests Occuring in Quick Succession

    - by Samuel
    This is a bit of an open ended question but we have a problem with a web application that on the final step of completing an order, multiple post requests are being made, sometimes up to 10 and all within a couple of seconds to the page. Theirs nothing unusual about the page, the user fills out a form which is then validated using the jQuery form validation plugin. We've seen this behavior exhibited over a couple of different browser types, notably IE6 but also IE8. We've also managed to trigger the bug ourselves but nothing out of the ordinary seems to occur on the browsers end, everything progresses as normal. Apache logs show that multiple post requests where made at the same time and the Rails logs show that multiple posts requests were also received by the application, leading me to think it's a problem with the browser. I've exhausted all avenues that I can think of for debugging so I'm throwing this out there to see if anyone has some ideas of what we could try or look for next.

  • Raphael how to get last path and last circle, if i have 2 elements in the paper?

    - by 3gwebtrain
    I need to find the last path or circle in a paper, in order to perform further calculations to draw more elements, and calling 'paper.bottom' only gets the last element. Is there any way to get shapes of specific types, e.g. bottom.path, bottom.circle or traverse for the n'th child? I want to avoid using jQuery selectors, as i can't retrieve any properties from those. An example of a paper populated with shapes: var paper = Raphael('paper',500,500); var c1 = paper.circle(100,100,50) var p1 = paper.path("M10 20l70 0") var c2 = paper.circle(200,100,50)

  • Cross-browser method for getting width and height of a DIV?

    - by thinkthank
    This is my first post, so please go easy on me. I'm sure I'm doing everything wrong. However, I couldn't find any posts that answered the question above. I use jQuery. I'm trying to find a way to get the current width and height of a DIV element, even if they're set to "auto". I've found many ways to do this, but no method returns the same width in IE. It is important that this method is cross-browser, as it will break the layout of the page if different numbers are returned in different browsers. .width() and .height() do not work because in IE, padding is subtracted (e.g. width() returns 25 where width is 30 and padding is 5). .outerWidth() and .outerHeight() are not consistent either. While they work IE (believe it or not) in FF, the padding is added again to the full width (e.g. outerWidth() returns 110 in FF where width is 100px and padding is 10px). Is there any way out of this mess without writing complex browser checks? Thanks!

  • Graceful Degradation with JSON.Parse

    - by Steve
    If a browser doesn't support JSON.parse, would it make sense to include json.js and call parseJSON in lieu? So the code would looks something like: var z; if (JSON.parse) z = JSON.parse(yada); else z = JSON.parseJSON(yada);

  • "Intercepting" user input into text box and removing it

    - by James P
    I have a text box that I would like to do some validation on. At the moment I have this code: function updateChanger() { // Validate input var likeMessage = validateInput($("#like").val()); alert(likeMessage); } function validateInput(input) { input = input.replace(/[^a-zA-Z0-9:\(\/\)\s\.,!~]/g, ""); return input; } This successfully trims out unwanted characters in the likeMessage variable, but the character still gets entered into the text box. I would like to stop that from happening. I know it will have something to do with $("#like").val() but the only thing I can think of is just chopping off the end character from the text box value, would this suffice? Thanks for any help!

  • JQuery Bind click event to appended element with an argument

    - by Gabor Szauer
    Hi guys, I'm trying to populate a ul list with some li elements and give each li element a link that calls the same function with a different argument. However it doesn't seem to work, i've attached the code below, CheckForNewMail is called on document load. Can anyone please help me out? function CheckForNewMail() { ////////////////////////////////////////////////////////////////// // This will be dynamic MailInInbox[0] = new Array("0", "Mail One"); MailInInbox[1] = new Array("12", "Mail Two"); MailInInbox[2] = new Array("32", "Mail Three"); MailInInbox[3] = new Array("5", "Mail Four"); ////////////////////////////////////////////////////////////////////// $('#mail-in-inbox').children().remove(); size = 4; element = $('#mail-in-inbox'); for(i = 0; i < size; ++i) { var link = $('<a href="#" class="inbox-link">'+ MailInInbox[i][1] +'</a>'); link.live('click', function() { LoadMailById(i); }); li = $('<li></li>'); li.append(link); element.append(li); } } function LoadMailById(id) { alert("Button "+ id +" clicked!"); }

  • Pre-formatting text to prevent reflowing

    - by mattjn
    I've written a fairly simple script that will take elements (in this case, <p> elements are the main concern) and type their contents out like a typewriter, one by one. The problem is that as it types, when it reaches the edge of the container mid-word, it reflows the text and jumps to the next line (like word wrap in any text editor). This is, of course, expected behavior; however, I would like to pre-format the text so that this does not happen. I figure that inserting <br> before the word that will wrap would be the best solution, but I'm not quite sure what the best way to go about doing that is that supports all font sizes and container widths, while also keeping any HTML tags intact. I figure something involving a hidden <span> element, adding text to it gradually and checking its width against the container width might be on the right track, but I'm not quite sure how to actually put this together. Any help or suggestions on better methods would be appreciated.

  • DOM - More than 5 'window' objects on one page

    - by Sid
    Hi, I'm trying to extract data from one of my websites using Greasemonkey. Problem is, the script runs 6 times because apparently the page loads content from 6 different servers. So if I put in an alert ("Hey"); the code runs 6 times and I get 6 alerts. How can I wait for the entire page to load and then start playing with the DOM. Also, I'm using jQuery. Thanks

  • plotting multiple google maps to page

    - by Roland
    I'm trying to append more than one Google Map to a page. But it seems like I'm having some trouble. This would be the template I'm using to ( with Handlebars.js ) to create the same block more than once, about 50 times : <script type="text/x-handlebars-template"> {{#each productListing}} <div class="product-listing-wrapper"> <div class="product-listing"> <div class="left-side-content"> <div class="thumb-wrapper" data-image-link="{{ThumbnailUrl}}"> <i class="thumb"> <img src="{{ThumbnailUrl}}" alt="Thumb"> <span class="zoom-image"></span> </i> </div> <div class="google-maps-wrapper"> <div class="google-coordonates-wrapper"> <div class="google-coordonates"> <p>{{LatLon.Lat}}</p> <p>{{LatLon.Lon}}</p> </div> </div> <div class="google-maps-button"> <a class="google-maps" href="#">Google Maps</a> </div> </div> </div> <div class="right-side-content"> <div class="map-canvas-wrapper"> <div id="map-canvas" class="map-canvas" data-latitude="{{LatLon.Lat}}" data-longitude="{{LatLon.Lon}}"></div> </div> <div class="content-wrapper"></div> </div> </div> </div> {{/each}} And I'm trying to append the map to the #map-canvas id. With the following block of code I'm doing the plotting : Cluster.prototype.initiate_map_assembling = function() { return $(this.map_canvas_wrapper_class).each(function(index, element) { var canvas = $(element).children(); var latitude = $(canvas).attr('data-latitude'); var longitude = $(canvas).attr('data-longitude'); var coordinates = new google.maps.LatLng(latitude, longitude); var options = { zoom: 9, center: coordinates, mapTypeId: google.maps.MapTypeId.ROADMAP }; var map = new google.maps.Map($(canvas), options); var marker = new google.maps.Marker({ position: coordinates, map: map }); }); }; This way I'm "looping" through all the parent classes of the id I'm trying to append the map to, but the map would only append to the first id. I tried to append it to all of the id's in other ways but with the same results. So what would you suggest me to do to make it work as I would expect it, append the map to each of the id's ?

    Hello, I would like to know if it is possible to instanciate a class by its id . For example we have a class extending Ext.grid.GridPanel with an id property, is it possible to instanciate the class just knowing his id (which is the component id in this case) ?

  • Relative Dates with Datejs

    - by Prasanna
    I have a requirement where in, I have to parse the dates relative to a date object returned from the server side. But the datejs library always considers only the browsers date object. The situation is something like this: The server gives back the date in PST and the browser is in IST. And all the inputs are getting parsed with respect to the current date in IST instead of current date in PST. Is there any way I could resolve this. Or could you suggest any workarounds. Thanks in advance.

  • jquery multiple select x rails edit action

    - by VP
    Hi, i'm using the JQUERY multiselectable plugin. Because it's get one select box and transform it in two, where you can move one selected option to another select box. The problem is that i'm facing some problems with the edit action. When i load the form, the selected values (that are saved in my model) are not being populated in the "selected" select box. There is anybody with a good idea about how to "automatically" move the selected values in my database from the "available to be selected" to "selected" options? For now i'm doing something like <%= select "product", :option_ids, options_for_select(Option.all.map { |opt| [opt.description, opt.id]}), {},{:multiple=> true,:class=>'multiselect'} %> Here i can see already the problem. I could just use as options_for_select just all options - the options that are already choosed in my model. The problem is how to update the select box with this information?

  • Cannot move ckeditor 4 selection to beginning

    - by Gary Hillerson
    I've been exploring numerous solutions in stackoverflow and elsewhere to try to get ckeditor 4 to scroll to the top after I've programmatically added a number of pages to it, using CKEditor's InsertHtml function. After adding my html, which looks fine, I want to position the cursor at the beginning. Here's one of a variety of things I've tried without success: function MoveCaretToStart(myEditor) { var range = new CKEDITOR.dom.range( editor.document ); range.selectNodeContents(editor.document.getBody()); range.moveToElementEditStart(range.root); // also tried range.collapse(true); range.select(); } ... MoveCaretToStart(CKEDITOR.instances['myEditor']); // which already has contents in it This doesn't throw any errors, but also doesn't move the cursor position (it remains at the end of the doc). I thought this one would be easy, but it sure hasn't been. Any help appreciated.
