  • javascript var assignment conversion to target type

    - by pbhd
    searching for a function, which converts rhs to the type of lhs. e.g. var x=false // x is boolean now; x=assign (x, "true"); //should convert "true" to boolean and return that x=assign (x, 1); // dto, convert 1 to true x=0 // x is number x=assign (x, "123"); // should convert "123" to 123; so such a function can be written, thats not the question. But: Is there somewhere a somehow complete implementation of such a thing? I started with something like that: function assign (v, x) { if (typeof v==typeof x) { return x; } switch (typeof v) { case 'boolean' : { return x=='true'?true:false; } case 'number' : { return parseFloat(x); } } return "xxx"; } var v=true; var x='true'; var r1=assign (v, x); console.log (typeof r1+ " "+r1); v=10; x="123"; var r1=assign (v, x); console.log (typeof r1+ " "+r1); which of course is not complete, but maybe shows what I'm goig for.

  • HTML/Javascript - Inconsistent positioning

    - by user1473358
    I'm in the process of designing this site http://www.parisgaa.org/parisgaels and have a problem. The image slider on the homepage messes up sometimes. Most of the time it works and looks fine, but other times its positioning seems to get messed up and it appears underneath the content that should be below it (i.e. with that content overlapping the image). You should be able to replicate this in Chrome - just refresh a couple of times. I'd appreciate any help at all.

  • javascript Programmically exit fullsreen

    - by Mark
    I understand why browsers would disallow websites from programically making the browser fullscreen. However, users typically expect the 'esc' button to exit from full screen, and browsers simply don't do that. Is there any way to get the browser to exit from full screen. Thanks.

  • Loop through Javascript array, print with string.

    - by Adam
    I have a simple array like: var myArr=["one","two","three"]; an I have a counting loop, which increases the value of var "i" by one. What I want to do is print the next value from the array each time the loop runs, next to a text string, like so: alert('value number '+myArr[i]+); But for some reason I can't get this to work. The following code works, so I'm assuming I'm not calling the counter right: alert('value number '+myArr[0]+);

  • Update someones birthday with javascript

    - by user2768038
    So far the only mathematical way I can think of doing it is this: var age = 18 var today = new Date(); var myDate = new Date(); myDate.setFullYear(2013,3,13); /* My birthday is april 13th */ var y = (today - myDate); var days = ( y / (1000*60*60*24)); if(days >= 360){ var age = age +1; } if(days >= 720){ var age = age +1; } //etc...... document.write(age); Is there a better way of doing the if statements? so that I don't have to write one out for every year? I can't think!

  • Form validation in JAvascript with Regexp

    - by Nikita Barsukov
    I have a webpage with an input field where only digits are allowed. The input field has an onkeyup event that starts this validating function: function validate() { var uah_amount = document.getElementById("UAH").value; var allowed = /^\d+$/; document.getElementById("error").innerHTML = document.getElementById("UAH").value; if (!allowed.test(uah_amount)) { document.getElementById("error").style.backgroundColor = "red"; } } Everything works as I expect until I hit Backspace button to remove some characters. In this case function always behaves as if I entered letters. How to correct this?
