  • Perl ||= operator for PHP and Javascript

    - by zaf
    Just been re-introduced to the Perl '||=' operator from the classic Orcish Maneuver example: keys my %or_cache = @in; @out = sort { ($or_cache{$a} ||= KEY($a)) cmp ($or_cache{$b} ||= KEY($b)) } @in; Is this operator available in PHP and Javascript? And if not, do these two languages allow user defined operators?

  • Validating javascript decimal numbers

    - by Click Upvote
    I'm using the following regexp to validate numbers in my javascript file: var valid = (val.match(/^\d+$/)); It works fine for whole numbers like 100, 200, etc, however for things like 1.44, 4.11, etc, it returns false. How can I change it so numbers with a decimal are also accepted?

  • which is the most accurate way to check variables type javascript

    - by mck89
    Hi, i need to check the type of a variable in javascript, i know 3 ways to do it: instanceof operator: if(a instanceof Function) typeof operator: if(typeof a=="function" toString method (jQuery uses this): Object.prototype.toString.call(a) == "[object Function]" Which is the most accurate way to do type checking beetween these solutions? and why? Please don't tell me that the last solution is better only because jQuery uses that.

  • Overriding !important style using Javascript

    - by Enrico
    Title pretty much sums it up. The external style sheet has the following code: td.EvenRow a{ display: none !important; } I have tried using: element.style.display = "inline"; and element.style.display = "inline !important"; but neither works. Is it possible to override an !important style using javascript. This is for a greasemonkey extension, if that makes a difference. Much appreciated, Enrico

  • Capturing Ctrl-Alt-Del in JavaScript/jQuery

    - by AJ
    While just playing with jQuery/JavaScript I ran across this problem. I could capture Alt and Ctrl keys but NOT Del and certainly not all of them together. $(document).ready(function() { $("#target").keydown(function(event) { if (event.ctrlKey && event.altKey && event.keyCode == '46') { alter("Ctrl-Alt-Del combination"); } }); }); Is it possible to capture all these three keys together?

If they say No, don't postback at all. Anyone know of an 'easy' way to do this?
