  • Ideas on limiting content to single printed page?

    - by James Skidmore
    I have 5-6 text areas that users fill out in a template (a couple of columns, basically a newsletter format). I'm needing to limit their content to one printed page, but I'm having a hard time coming up with practical solutions. The printed format (margin, font size, etc.) will be the same for all users, as it's printed from a central source. I've had a couple of ideas, but all of them seem rather unreliable and difficult to implement: Determine height of content using JavaScript and estimate the number of printed pages from that. The problem with this is that browser font sizes can vary, it's only a rough estimate (pixels to inches), etc. Limit the number of characters. This is problematic because there are various text fields, certain characters (like M) take up more space than others (like I), and line breaks obviously count for much more. What ideas do you all have? I appreciate your help!

  • jQuery: what is it "forbidden" to do in plain Javascript

    - by flybywire
    A jQuery best practices question. I am writing a very jQuery intensive web page. I am new to jQuery and notice its power, but as I come with heavy javascript experience and knowledge, my question is: What should be done in jQuery and what in plain javascript. For example, there are callbacks that send a plain DOM object as an argument. Should I use that or should I wrap it ( like $(this)). Does it matter if I do this.x=y or $(this).attr("x", y).

  • Why does this jQuery dropdown menu display subcategory selections only for certain top-level categories?

    - by chunkymonkey
    I'm trying to implement a dropdown menu based on a jQuery plugin from Filament Group: http://jsfiddle.net/chunkymonkey/Pr8k4/ What I am having difficulty fixing is a bug where certain categories can be expanded to show their subcategories while others show nothing when opened up. For example: Alternative Rock can be expanded to show its multiple subcategories . . . BUT . . . World Music, which has equally many subcategories, shows no subcategories when expanded. I would be very grateful if anyone could help me figure out what's causing this. Thanks. UPDATE: Just noticed this problem may be Chrome-specific(??). I just tested it in IE8 and Firefox and it seems to work correctly in both.

  • Order words by number of letters, then place words neatly

    - by bmaster
    I have a list of words in javascript similar to this: var words = ["mine", "minute", "mist", "mixed", "money", "monkey", "month", "moon", "morning", "mother", "motion", "mountain", "mouth", "move", "much", "muscle", "music", "nail", "name", "narrow", "nation", "natural", "near", "necessary", "neck", "need", "needle", "nerve", "net", "new", "news", "night"]; The words can be 1-25? letters long. I have a div id="words", with a set width of 700px (but I might change it from this). Using css/javascript/jquery, how can I make it: Order the words by number of letters Place the words inside the div tag, left to right, but so that there are no gaps at the right edge of the words div, and there is even spacing between words on a line. Each word should have a border around it and a background. Like this: |reallylongwordssdf shorterwordfdf dfsdfsdfsdf sdfsdfsdf| |sdfsdfsdf sdffsdop sdfjpogs sdfsds dfsdsd dfsdsd dfsdsd| I really have no idea where to begin with this. Perhaps I could manage to write code to order the words by number of letters, but after that, I'd be stuck. Edit: I forgot to add, the words must be links.

  • A question on webpage representation in Java

    - by Gemma
    Hello there. I've followed a tutorial and came up with the following method to read the webpage content into a CharSequence public static CharSequence getURLContent(URL url) throws IOException { URLConnection conn = url.openConnection(); String encoding = conn.getContentEncoding(); if (encoding == null) { encoding = "ISO-8859-1"; } BufferedReader br = new BufferedReader(new InputStreamReader(conn.getInputStream(),encoding)); StringBuilder sb = new StringBuilder(16384); try { String line; while ((line = br.readLine()) != null) { sb.append(line); sb.append('\n'); } } finally { br.close(); } return sb; } It will return a representation of the webpage specified by the url. However,this representation is hugely different from what I use "view page source" in my Firefox,and since I need to scrape data from the original webpage(some data segement in the original "view page source" file),it will always fail to find required text on this Java representation. Did I go wrong somewhere?I need your advice guys,thanks a lot for helping!

  • How to have multiple parts of a website in one page

    - by stas
    I want to make a website that will have multiple pages, but because of a unique navigation bar, I cannot simply link to a new file for each page. What is the best way to accomplish this. Some possibilities that I can think of are having all of them on one page, but using css and javascript to move the other pages offscreen, or using iframes and loading them with javascript. Could someone please direct me to some examples or tutorials?

  • text fields and PHP

    - by moustafa
    Does anyone know if it's possible to have several text fields that place the data into different spots in the same web page. If needed I could just use two pages, it doesn't really matter. I've heard this requires a PHP script, but I'm not sure how to set this up.

  • How do you make a wrapped div fill the window horizontally?

    - by Alex Parkinson
    I have a div which is contained by another 960px-wide centered div. I'm adding a background to the inner div which should expand all the way to the window's edges horizontally, essentially escaping the boundaries of its container. If I apply a large negative margin and equal amount of padding, this works on the left side, but the right side causes a scroll bar to appear. Does anyone know how I can achieve this without causing scroll bars?

  • Padding/Margin/Border On Element Does Not Change DIV Height

    - by ryandlf
    Here is a very simply jsFiddle to demonstrate my problem: http://jsfiddle.net/ryandlf/mSmUv/4/ When an element has a top padding or margin and it sits on the first line within a div, the div does not respect that padding or margin and push the element down. In most cases this isn't an issue, but for example, if I have a button that has a top border and padding the top of the border will be cut off because the div is not taking into consideration the padding value. Is there a workaround for this other than just blindly setting margins or padding on every container div element and hoping I have added enough to account for any internal element that might be affected?

  • Is angularjs capable of filtering based on keywords?

    - by Alex90
    I have 30 categories in mysql. I have 450 subcategories which are related to the 30 categories in another table. Categories table id _ title _ Keywords 1 _ Animals _ animal, animals, pet, parrot 2 _ Books _ books, book, educational n _ xxx _ xxx Subcategories table id _ ref _ title _ keywords 1 _ 1 _ cats _ cats, persian cat, bengal cat 2 _ 1 _ dogs _ dogs, labrador, golder retriver 3 _ 2 _ Classic _ The davinci code, books, book, classical books I need to implement the filter to a textfield. If the users enters labrador in the textfield then show the categories or/and subcategories which contain 'labrador' in the keywords. In this case the "dogs" subcategory would appear! I know that this has been done using jquery. But is there anyway to implement this with angularJs? If you got a jsfiddle then it would be awesome! :) Thank you

  • jQuery toggle menu dropdown

    - by Seong Lee
    I am working on a menu navigation that has parent horizontal bar as static and a vertical accordion child menu that interacts with the parent. I have them working fine except one part where I want to toggle show() and hide() child menu when clicked on the same parent menu item. I've looked at toggle() jQuery API but couldn't get it working properly. The following is only a script for parent part which I got rid of toggle() for now. $(function () { $('#mainMenu > ul > li > a').click(function () { $('#mainMenu li').removeClass('active'); $(this).closest('li').addClass('active'); if ($(this).text() == "1st click") { $('#subMenu > ul').siblings().hide(); $('#subMenu > ul:nth-child(1)').show(); } else if ($(this).text() == "2nd click") { $('#subMenu > ul').siblings().hide(); $('#subMenu > ul:nth-child(2)').show(); } }); }); The Full code that isolates the problem is available here

  • Is it possible to hide the cursor in a webpage using CSS or Javascript?

    - by yeyeyerman
    I want to hide the cursor when showing a webpage that is meant to display information in a building hall. It doesn't have to be interactive at all. I tried with the cursor property and a transparent cursor image but I didn't make it work. Does anybody know if this can be done? I suppose this can be thought as a security threat for a user that can't know where he is clicking on, so I'm not very optimistic... Thank you!

  • Password verification; Is this way of doing it safe?

    - by Camran
    I have a classifieds website, where everybody may put ads of their products. For each classified, the user has to enter a password (so that they can delete the classified whenever they wish). So basically, when somebody wants to delete a classified, they click on the classified, click on the delete button, and enter the pass. I use MySql as a database. I use this code basically: if ($pass==$row['poster_password']) where row[poster_password] is fetched from MySql... What do you think? Thanks
