  • HTML Scraping in Php.

    - by tsellon
    I've been doing some html scraping in PHP using regular expressions. This works, but the result is finicky and fragile. Has anyone used any packages that provide a more robust solution? A config driven solution would be ideal, but I'm not picky.

  • Best Practice: User generated HTML cleaning

    - by Martin
    I'm coding a WYSIWYG editor width designMode="on" on a iframe. The editor works fine and i store the code as is in the database. Before outputing the html i need to "clean" with php on the server-side to avoid cross-site-scripting and other scary things. Is there some sort of best practice on how to do this? What tags can be dangerous? UPDATE: Typo fixed, it's What You See Is What You Get. Nothing new :)

  • How to ignore events in html table

    - by Yaron
    Hello, I have a transparent table with width:100% which contains some html content. I use the table in order to position a content element on the screen center. The table captures mouse events, and the user can't press on links which are positioned beneath it (although it is transparent). Is there a way to tell the browser to ignore events on the table? I want to capture events only from the content inside the table (and from the rest of the site). Thanks Yaron

  • Using jquery to prevent resubmitting form

    - by Tony
    I use jquery's .submit() to intercept user's submit event, however I found a problem. When the user single click the submit button, the form is submitted normally, but if a user deliberately fast click it multiple times, it will submit multiple times, which will cause duplicated data in the database. What's the solution for this kind of problem ?

  • Hide html horizontal but not vertical scrollbar

    - by williamjones
    I have an html textarea that is of fixed width, but variable height. I would like to set overflow:scroll and be able to show a vertical scrollbar, but not a horizontal one. I am not able to use overflow:auto due to other things specific to my situation. I know there is no way using CSS 2 to show only vertical but not horizontal scrollbars. Is there anything I can do with javascript to hide the horizontal scrollbar?

  • slowness in IE 8 IE9 while drawing tables in a html page

    - by GustlyWind
    My HTML page contains many tables,with numerous tr and td. While rendering in IE8/IE9 the its very slow but in Firefox its fast. I had read somewhere while drawing tables if the tables are not of fixed width, IE calculates the width every time and renders so usually slow. Right now i am adding Table style="table-layout:fixed" which made me feel its faster. Are there any similar styles that can be added to tr and td as well.Also suggest if there any other attribtes that can be added to a table

  • What is the process of turning HTML into Postscript programmatically

    - by Dean
    I am trying to understand what the process is of turning HTML into a PDF/Postscript programmatically All Google searches turn up libraries to do this, but I am more interested in the actual process required. I know you could just set up a Postscript printer and print directly to that, but some of these libraries appear to create the PDF on the fly to allow previews etc. has anyone had any experience in this, or can provide any guidance?

    - by Kyle Sevenoaks
    Is there a way to force the dropdown direction of a select element in HTML down? At the moment we have a product display page, the select box appears below the halfway mark of the screen in a widescreen resolution and therefore makes the dropdown go up. Is this possible? Thanks.

  • HTML-like GUI Framework in Java

    - by wintermute
    I was recently brought onto a project where we are developing a lot GUI elements for BlackBerry devices. The standard RIM APIs are pretty basic, almost never do what is required and are difficult or impossible to extend, so we end up re-implementing chunks of it. Currently the code we have isn't super organized and factored so there are lots of little tricks that get implemented over and over again. I had a thought about how to aid development efforts on this platform and wanted to see if the community could tell me if I'm still sane or if I've gone totally nuts. By far, the biggest organizational problem I've run into is making sure that each screen is laid out properly with proper padding and such. The current approach is to manually keep track of padding like so: protected void sublayout(int width, int height) { final int padding = 5; int y = padding; int x = padding; layoutChild(_someChild, width - padding * 2, height / 3 - padding * 2); setPositionChild(_someChild, x, y); y += _someChild.getHeight() + padding; // Calculate where to start drawing next. /* ... snipped ... */ } As you can see, positioning elements on a screen is a nightmare due to the tedium. I have investigated other GUI frameworks but, for a variety of reasons, it is difficult to find one that suites our purposes. One potential solution that came to me is to create a GUI framework who's API resembles HTML/CSS. This would allow for things like padding, margins, borders and colours to be handled through a sort of CSS API while the content would be organized using the HTML part of the API. It might look something like this: public class OptionsScreen extends Document { public OptionsScreen() { // You would set the style (like CSS style) through the constructor. Div content = new Div(new Style(new Padding(5), Color.BLACK)); // Then build up a tree of elements which can each have their own style's. // Each element knows how to draw itself, but it doesn't have to worry about // manually handling things like padding. // content.addChild(new P("This is a paragraph", new Style(new Padding(), Color.RED))); Ul list = new Ul(); list.addChild(new Li("item 1")); list.addChild(new Li("item 2")); content.addChild(list); addChild(content); } } I can imagine this making it easier to customize the UI of our app (which is very important) with different fonts, colours and layouts. Does this idea belong on The Daily WTF or do you think there is some promise?
