  • Detecting regular expression in content during parse

    - by sonofdelphi
    I am writing a parser for C. I was just running it with some other language files (for fun, to see the extent C-likeness). It breaks down if the code being parsed contains regular expressions... Case 1: For example, while parsing the JavaScript code snippet, var phone="(304)434-5454" phone=phone.replace(/[\(\)-]/g, "") //Returns "3044345454" (removes "(", ")", and "-") The '(', '[' etc get matched as starters of new scopes, which may never be closed. Case 2: And, for the Perl code snippet, # Replace backslashes with two forward slashes # Any character can be used to delimit the regex $FILE_PATH =~ s@\\@//@g; The // gets matched as a comment... How can I detect a regular expression within the content text of a "C-like" program-file?

  • Prototype and jQuery concatenation failure

    - by Corey Hart
    I found something strange when trying to concatenate prototype and jQuery. It seems as though when concatenated, the $ jquery reference doesn't get overwritten by prototype. I've built two test cases to single this out, and it's failing in Chrome8 and FF 3.6. Test Case 1 - Without Concatenation jQuery and Prototype are loaded separately with different script tags. jQuery is loaded first, Prototype second. Test Case 2 - With Concatenation jQuery and Prototype are concatenated into a single file, and loaded with a single script tag. jQuery is first in the script, and prototype is added second. These should act identically, but the second test is throwing errors because the $ function in prototype doesn't overwrite the $ jquery reference. Did I set these up wrong, or are browsers rendering javascript differently when it's all in the same file?

  • Trying to make my leaflet map work on internet explorer

    - by user1270657
    I have been tearing my hair out of late trying to get my web map working on internet explorer. It's working flawlessly on every other major browser but none of the content will load in IE. Anyone out there who's good at browser testing that could help out? I know the leaflet javascript api, which I'm using for this project, supports IE in theory. In practice this isn't working out too well... Link to a live version of the web map: https://mywebspace.wisc.edu/axler/SLRE_Deep_Map/index2.html Let me know if there is anything else I could add that would help in deciphering this problem... Thanks!

  • How to use FBJS to get the language preference of the user?

    - by ed.talmadge
    I'm modifying an existing FaceBook application. The FaceBook application is generated by another application, so I don't have much control over it. I can only add html/javascript. My goal is to use FBJS to detect the current language setting of the user and display a different message depending on their language. For example, if the user has their language setting set to Spanish, then I would like to show a message in Spanish on my FaceBook application. How can I do this?

  • Disable page redirects using Greasemonkey

    - by Tomer Cohen
    A website I wish to tweak is using window.location in order to redirect specific users to a blocking page. That website is doing it in plain <script> tag, so it is impossible to bypass it by overriding the onload event using document.body.setAttribute('onload','');. Is there another way to inject my code to the page without using Firefox extensions such as NoScript? <!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"> <head> <title></title> <script type="text/javascript"> if (1) window.location="http://example.net" </script> </head> <body></body> </html>

  • How to automaticly add a page number to all internal links on the HTML page?

    - by Tomasz
    In print mode, I would like to render such a links: <a href="#targetPage">link</a> like this: <a href="#targetPage">link (page 11)</a> (suppose the target page is on 11. page in print preview). It is possible to add page number using counters to the page footer with plain CSS, but could I use this in more "the way I want it" way? The solution doesn't need to be cross-browser (FF/Chrome is enough), any CSS/Javascript tricks are allowed...

  • Manually force touch points to reset in Windows 8?

    - by loyalpenguin
    Hi I developed a HTML5/JAVASCRIPT app that is supported using advertisement for the Win8 store. I just by chance happened to notice that if you touch the screen, drag your finger over the advertisement, and release your finger on top of the advertisement that the specific touch is not released and instead when you touch again it registers as a separate touch. This has caused my app to behave expectantly when the user interacts with the app using touch. I wanted to know if it was possible to force the touches to reset so that when the user touches the screen again it is always using "Touch(0)".

  • Twitter oauth/request_token failing sometimes

    - by Techpriester
    Hello there. I'm implementing Twitters OAuth for Adobe AIR in Javascript. My problem is, that out of 100 requests to api.twitter.com/oauth/request_token about 30 fail with the usual error message: Failed to validate oauth signature and token The other 70% of requests produce a correct response, so I believe that my algorithm for signing is correct. I've read about invalid timestamps in a lot of forums and mailing lists but that is not the problem. My timestamps are correct. I also checked, if the nonces are unique, so that's not the cause either. Any ideas why this is happening?

  • asp.net mvc script and style references

    - by tom
    I'm trying to include script and style references that will not break on deployment, however I can not even get the references to work locally. I have tried using Url.Content() and MVCContrib's <%=Html.ScriptInclude("")%>. My scripts are in a Scripts folder on the root of the site; my styles are in the usual Content/css/ folder. The scripts render like this: <script type="text/javascript" src="/Scripts/MicrosoftAjax.debug.js" ></script> This will not work in a view page in the Views folder. What am I doing wrong and what is the best way to handle this? I would have thought Url.Content() would at least work for styles but used in my master page, the link rendered <link href="/Content/css/Site.css rel="stylesheet" type="text/css" /> This does not work, because the Master Page is in a Shared folder, so what is really the way forward with this?

  • Modifying a global variable from <a href>

    - by a_m0d
    I have created some code to popup a confirm dialog if a user tries to leave a page without saving their changes. However, I don't want the confirmation dialog to popup if the user has clicked the "Save" button. I have some code at the top of my file which looks like this: var confirmClose = false; window.onbeforeunload = function(evt) { if (confirmClose == true) { message = "There are unsaved changes on this page. Are you sure you wish to leave?"; if (typeof evt == 'undefined') { evt = window.event; } if (evt) { evt.returnValue = message; } return message; } } Further down on the page I have a link which looks like this: <a href="javascript:confirmClose=false;$('#stockForm').submit()" title="Save" class="button positive" id="stockFormSubmit">Save</a> However, this doesn't seem to work - it doesn't seem to change the value of confirmClose, and changing it to window.confirmClose didn't help either. What am I doing wrong here?

  • XML DOM Manipuation

    - by kunalsawlani
    Hi, I am new to XML and have been trying some simple examples and they work fine. I want to do something like the following, but I am not able to figure out how to go about doing this. I have a HTML web page, where the user types in some data in an input field. I want to take that data, parse it to create an XML string, and the apply XSLT transformation to it, and display the result back on the page. All this needs to be done on the client browser, with JavaScript. If some one could point out the steps or the general procedure to go about doing this, it would be great. I have been looking over the net, but the information is so vast, that I have not been able to locate exactly what I need. Thanks

  • Best Technologies for AJAX Web Development

    - by floatingfrisbee
    Hey Everyone, I have some experience in AJAX development, mostly on .NET and MooTools. However, I want to learn more and see what others out there thought about the various other options available. I am looking more for advise about the front end. The back end, I will most probably be coding up in .NET using c# and WCF services. Please feel free to provide me as much information as you can. Also I would appreciate any links to resources. List of Options (feel free to add) Write my own Javascript Use a frame work like MooTools, JQuery etc. Which one is better? Use Google Web Toolkit. Am I tying myself to limitations of GWT? Or are there not limitations? ASP.NET AJAX WPF (Will this run on non IE browsers?) Flash (it'll be a pain to learn action script) Thanks Jaspreet

  • How do you determine up/down latency of a web app.

    - by Brodie
    I am trying to work out how to calculate the latency of requests through a web-app (Javascript) to a .net webservice. Currently I am essentially trying to sync both client and server time, which when hitting the webservice I can look at the offset (which would accurately show the 'up' latency. The problem is - when you sync the time's, you have to factor in latency for that also. So currently I am timeing the sync request (round trip) and dividing by 2, in an attempt to get the 'up' latency...and then modify the sync accordingly. This works on the assumption that latency is symmetrical, which it isn't. Does anyone know a procedure that would be able to determine specifically the up/down latency of a JS http request to a .net service? If it needs to involve multiple handshakes thats fine, what ever is as accurate as possible. Thanks!!

  • xslt dropdown problems

    - by Primetime
    I have a page with two drop down boxes created in a xslt. I am using onchange in both blocks to call a javascript function. If both drop downs are loaded on the page only the first drop down has a working onchange. I checked the view source code and it shows both onchange events. Does anyone have any idea how to fix this? ex: two drop downs, select first one, it refreshes, select second it does nothing, select first one and it still refreshes. code removed.

  • Dynamically render partial templates using mustache

    - by btakita
    Is there a way to dynamically inject partial templates (and have it work the same way in both Ruby & Javascript)? Basically, I'm trying to render different types of objects in a list. The best I can come up with is this: <div class="items"> {{#items}} <div class="item"> {{#is_message}} {{< message}} {{/is_message}} {{^is_message}} {{#is_picture}} {{< picture}} {{/is_picture}} {{^is_picture}} {{/is_picture}} {{/is_message}} </div> {{/items}} </div> For obvious reasons, I'm not super-psyched about this approach. Is there a better way? Also note that the different types of models for the views can have non-similar fields. I suppose I could always go to the lowest common denominator and have the data hash contain the html, however I would rather use the mustache templates.
