  • How can I catch all ajax requests in javascript ?

    - by Annan
    Is it possible to have a global event handler for ajax requests that automatically gets called when any ajax request returns ? I'm interested in this because I'm making a greasemonkey script for an ajax site. In previous scripts I either ran the main function every few seconds or overwrote parts of the site's javascript, both things that are messy.

  • How do I protect my website from javascript injection attacks when using rich text editors?

    - by VJ
    Hi all I am using the markitup editor to get the value for one of my fields and storing it a sql server 2008 db. Now I guess the problem is people having script tags and javascript in the editor and injecting malicious scripts and I have my validate input turned false. So can anyone suggest me a way to write a custom validation method that maybe checks for script tags and removes them...or just guide me through the steps i need to do ?...also are there other things also that I should be worried about..?

  • How can I test potentially browser crashing javascript without having to restart my browser?

    - by yaya3
    I've been having a crack at some of the problems over at http://projecteuler.net/ with JavaScript. I've been using a simple html page and running my code in script tags so I can log my results in the browsers' console. When experimenting with loops I sometimes cause the browser to crash. Is there a better environment for me to do this kind of development in, or anything I can do to allow me to carry on testing in the browser?

  • Javascript (and HTML rendering) engine without a GUI for automation?

    - by MTsoul
    Are there any libraries or frameworks that provide the functionality of a browser, but do not need to actually render physically onto the screen? I want to automate navigation on web pages (Mechanize does this, for example), but I want the full browser experience, including Javascript. Thus, I'd like to have a virtual browser of some sort, that I can use to "click on links" programmatically, have DOM elements and JS scripts render within it, and manipulate these elements. Solution preferably in Python, but I can manage others.

  • How do I get javascript-generated image maps to work with internet explorer?

    - by schwerwolf
    I'm using javascript to generate a high resolution grid for an image that I generated on a web server. The high-resolution grid is composed of a 'map' element with hundreds of 'area' child elements. Each 'area' element has onmouseover attribute that causes the display of a popup box. After assigning the map to the img (via the usemap attribute), Internet explorer ignores the 'onmouseover' attribute of the area elements that I added via javascript. The behavior is not caused by syntactical variations between IE and other browsers. A static map behaves correctly. Only the elements that I add dynamically to an existing image map fail to fire their corresponding mouse-over events. How can I get IE to fire the mouse-over event for the added 'area' elements? function generate_image_map ( img ) { var tile_width = 8; var tile_height = 10; var plotarea_left = 40; var plotarea_top = 45; var column_count = 100; var row_count = 120; var img_id = YAHOO.util.Dom.getAttribute(img, "id"); var img_map_id = YAHOO.util.Dom.getAttribute(img, "usemap"); var original_map = YAHOO.util.Selector.query(img_map_id)[0]; var area_nodes = YAHOO.util.Selector.query("area", original_map); var last_node = area_nodes[area_nodes.length - 1]; for (var y = 0; y < row_count; y++) { var top = Math.round(plotarea_top + (y * tile_height)); var bottom = Math.round(plotarea_top + (y * tile_height) + tile_height); for (var x = 0; x < column_count; x++) { var left = Math.round(plotarea_left + (x * tile_width)); var right = Math.round(plotarea_left + (x * tile_width) + tile_width); var area = document.createElement("area"); YAHOO.util.Dom.setAttribute(area, "shape", "rect"); YAHOO.util.Dom.setAttribute(area, "onmouseover", "alert('This does not appear in IE')" ); var coords = [ left, top, right, bottom ]; YAHOO.util.Dom.setAttribute(area, "coords", coords.join(",")); YAHOO.util.Dom.insertBefore(area, last_node); } } }

  • What is the best method to convert to an Integer in JavaScript?

    - by Mathew Byrne
    There are several different methods for converting floating point numbers to Integers in JavaScript. My question is what method gives the best performance, is most compatible, or is considered the best practice? Here are a few methods that I know of: var a = 2.5; window.parseInt(a); // 2 Math.floor(a); // 2 a | 0; // 2 I'm sure there are others out there. Suggestions?

  • Is there a way using jQuery or Javascript to force a page to open in Firefox?

    - by sadmicrowave
    Is there a way using jQuery or Javascript to force a page to open in Firefox? For example, if the user has their default browser set to internet explorer, but they have firefox on their computer - open a new firefox window with the intended page. If so, I would need to check to see if they have firefox on their machine; otherwise, redirect to the mozilla firefox download site... any suggestions?
