• Is there a way to get a reference to all the paragraphs or headings in a web page in JavaScript?

  - by mattbd

  I'm writing a simple Greasemonkey script to strip out all the images, headings and paragraphs from a web page (it's because someone wants to use images of several popular websites with the images and text removed in a presentation about branding of websites). I've figured out how to do so with images by using a for loop and the document.images array like this: var i = 0; var imglngth = document.images.length; for(i=0;i<imglngth;i++) { document.images[i].style.display="none"; } However, I don't believe there's an object representing paragraphs or headers. Any suggestions as to how I could implement this?

• link_to syntax with rails3 (link_to_remote) and basic javascript not working in a rails3 app?

  - by z3cko

  i am wondering if the basic link_to syntax is completely broken in current rails3 master or if i am doing some wrong syntax here. = link_to "name", nil, :onlick => "alert('Hello world!');" should actually produce an alert on click. very simple. does not work on my rails3 project! (also no error output!) any ideas? for the general link_to syntax i could not find an example where i could combine a link_to_remote with a confirmation, remote and html class (see my try below) = link_to "delete", {:action => "destroy", :remote => true, :method => :delete, :confirm => "#{a.title} wirklich L&ouml;schen?" }, :class => "trash" even the rails3 api does not help me here: http://rails3api.s3.amazonaws.com/index.html help!

• Javascript regular expressions: how to match ONLY the given characters?

  - by Dfowj

  I'm trying to use a regex like /[computer]{3,8}/ to get any words containing only the letters in computer ranging from 3 to 8 letters long. That regex instead captures all words containing ANY of the letters in [computer]. I've been looking at regular expression examples, but i can't quite figure it out... How do i modifiy this regular expression to capture words containing ONLY the letters in computer (with a length of 3 to 8)?

• How can I unobtrusively disable submit buttons with Javascript and Prototype?

  - by Frew

  So I found this recommendation, but I can't quite seem to figure out how. This is the code I originally started with: function greySubmits(e) { var value = e.srcElement.defaultValue; // This doesn't work, but it needs to $(e).insert('<input type="hidden" name="commit" value="' + value + '" />'); // This causes IE to not submit at all $$("input[type='submit']").each(function(v) {v.disabled = true;}) } // This works fine Event.observe(window, 'load', function() { $$("input[type='submit']").each(function(e) { Event.observe(e, 'click', greySubmits); }); }); Anyway, I am pretty close, but I can't seem to get any further. Thanks for any help at all! Update: Sorry, I guess I wasn't entirely clear. I'd like to disable all of the submit buttons when someone clicks a submit button. But I do need to send along the value of the submit button so the server knows which button I clicked, hence the insert call. (Note: insert does not create a child of the element you call it on.) And then after disabling the submit buttons I need to call the containing form of the submit buttons submit call, as IE will not submit after you disable the button. Does that make sense?

• How to handle uncaught Exceptions in javascript without a try/catch-block?

  - by user344238

  What i try to accomplish is to register a global handler to catch all uncaught exceptions. Searching the web i only managed to find people pointing out window.onerror but this doesn't do the trick for me. Apparently window.onerror only gets called upon errors and not upon exceptions. Assume the following code: function windowError(message, url, line) { alert(message, url, line); } window.onerror=windowError; throw("uncaught"); The obviously uncaught exception won't trigger the windowError handler. (Using Firefox 3.6.3) Any suggestions?

• JavaScript: Container with draggable. Constrain draggable to a circle shape, in container.

  - by ritsuke

  Hey guys, I'm looking for a simple solution to place a draggable element inside of a box container. When the user begins to interact with the draggable, the draggable element should remain constrained to a circular shape, within the container. At a complete loss as to how I should accomplish this. Thank you! :-) Additional: Box container would be 100 pixels wide and tall Draggable would be 20 pixels wide and tall http://tool-man.org/examples/dragging.html This is on the TODO list, but of course this site is no longer maintained

• Is there a method I can override on a JavaScript object to control what is displayed by console.log?

  - by agnoster

  I'm thinking in particular of Chrome, though Firebug would be interesting to. I've tried toString() and valueOf(), but neither of those seem to be used. Interestingly, if I take a function it'll display the function definition - but then if I add a toString() method it will show null! var a = function(){}; console.log(a); // output: function (){} a.toString = function(){ return 'a'; }; console.log(a); // output: null a.valueOf = function(){ return 'v'; }; console.log(a); // output: null Any ideas?

• How to hook onclick event for each cell in a table in Javascript?

  - by MartyIX

  I was thinking if there's a better solution for adding onclick handler to each cell in a table than this approach: http://stackoverflow.com/questions/1207939/adding-an-onclick-event-to-a-table-row Better in the way that I wouldn't need to set "cell.onclick = function" for each cell. I just need to get the coordinations of a cell where user clicked. Thanks!
