  • Javascript setFullYear

    - by user187870
    var currentDate=new Date(); currentDate.setFullYear(2011); alert(currentDate); == this works, it sets the year to 2011 as expected. alert((new Date()).setFullYear(2011)); == this one doesn't work. Any idea why? Am I misunderstanding the syntax?

  • Split a sting array into a number array in javascript

    - by Wesley Skeen
    I am reading a value from a dropdown list depending on what option is selected. I am using jqPlot to graph the values. jqPlot expects an array of values like [91, 6, 2, 57, 29, 40, 95] but when I read the value in from the dropdown box it is coming in as a whole string "[91, 6, 2, 57, 29, 40, 95]" I tried splitting it but I got ["91", "6", "2", "57", "29", "40", "95"] which wont display the graph correctly. Is there anybody that has encountered something like this before and what can I do to make my values convert into a number array. Thanks for any help

  • Javascript - undefined cookie value?

    - by Computeras
    Try running the code, I know the problem is in the 1. part. Thanks in advance, P.S. I'm a newbie in JS. <html> <head> <script> { //1. part var Cookies = ""; function createCookie(name,value,days) { if (days) { var date = new Date(); date.setTime(date.getTime()+(days*24*60*60*1000)); var expires = "; expires="+date.toGMTString(); } else var expires = ""; document.cookie = name+"="+value+expires+"; path=/"; } function readCookie(name) { var nameEQ = name + "="; var ca = document.cookie.split(';'); for(var i=0;i < ca.length;i++) { var c = ca[i]; while (c.charAt(0)==' ') c = c.substring(1,c.length); if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length,c.length); } return null; } function eraseCookie(name) { createCookie(name,"",-1); } //2. part function saveIt(name) { var x = document.forms['cookieform'].cookievalue.value; if (!x) alert('Please fill in a value in the input box.'); else { Cookies.create(name,x,7); alert('Cookie created'); } } function readIt(name) { alert('The value of the cookie is ' + Cookies[name]); } function eraseIt(name) { Cookies.erase(name); alert('Cookie erased'); } function init() { for (var i=1;i<3;i++) { var x = Cookies['ppkcookie' + i]; if (x) alert('Cookie ppkcookie' + i + '\nthat you set on a previous visit, is still active.\nIts value is ' + x); } } } </script> <body> <form name = "forma"> <input type = "text" name = "cookievalue"> <input type = "button" value = "Spremi" onClick = "saveIt('ppkcookie1')"> <input type = "button" value = "Ispisi" onClick = "readIt('ppkcookie1')"> </form> </body> </html>

  • JavaScript sleep

    - by Diazath
    yes, i know - that question has thousands of answers. please, don't tell me about "setTimeout" method becasuse - yes, everything is possible with that but not so easy as using sleep() method. for example: function fibonacci(n) { console.log("Computing Fibonacci for " + n + "..."); var result = 0; //wait 1 second before computing for lower n sleep(1000); result = (n <= 1) ? 1 : (fibonacci(n - 1) + fibonacci(n - 2)); //wait 1 second before announcing the result sleep(1000); console.log("F(" + n + ") = " + result); return result; } if you know how to get the same result using setTimeout - tell me ;) fibanacci is pretty easy task, because there not more than 2 recursions, but how about n-recursions (like fib(1) + fib(2) + .. + fib(n) and sleep after every "+"? nah, sleep would be muuuuuch easier. but still i can't get working example of implementing it. while (curr - start < time) { curr = (...) } is tricky, but it won't work (just stops my browser and then throw all console.logs at once).

  • Can't access Elements previously created by innerHTML with Javascript/Prototype

    - by Joe Hopfgartner
    I am setting the innerHTML variable of a div with contents from an ajax request: new Ajax.Request('/search/ajax/allakas/?ext_id='+extid, { method:'get', onSuccess: function(transport){ var response = transport.responseText || "no response text"; $('admincovers_content').innerHTML=response; }, onFailure: function(){ alert('Something went wrong...') } }); The response text cotains a form: <form id="akas-admin" method="post" action="/search/ajax/modifyakas/"> <input type="text" name="formfield" value="i am a form field"/> </form> Then I call a functiont that should submit that form: $('akas-admin').request({ onComplete: function(transport){ //alert('Form data saved! '+transport.responseText) $('admincovers_content').innerHTML=transport.responseText; } }); The problem is $('akas-admin) returns null , I tried to put the form with this id in the original document, which works. Question: Can I somehow "revalidate" the dom or access elements that have been inserted with innerHTML? Edit Info: document.getElementById("akas-admin").submit() works just fine, problem is i don't want to reload the whole page but post the form over ajax and get the response text in a callback function. Edit: Based on the answers provided, i replaced my function that does the request with the following observer: Event.observe(document.body, 'click', function(event) { var e = Event.element(event); if ('aka-savelink' == e.identify()) { alert('savelink clicked!'); if (el = e.findElement('#akas-admin')) { alert('found form to submit it has id: '+el.identify()); el.request({ onComplete: function(transport){ alert('Form data saved! '+transport.responseText) $('admincovers_content').innerHTML=transport.responseText; } }); } } }); problem is that i get as far as alert('savelink clicked!'); . findelement doesnt return the form. i tried to place the save link above and under the form. both doesnt work. i also think this approach is a bit clumsy and i am doing it wrong. could anyone point me in the right direction?

    - by Doug
    I am working on a website which I would like to work on iPhones, however I want it so they can tap and hold a button and have it continue firing the onclick event. I got it to work in other browsers, but the iPhone is the only one that will need to hold down the button. Is there a way to repeat a function when holding down the button? Thanks.

  • Javascript: setTimeout() - help needed

    - by ilkin
    Hi guys, I'm currently doing a highlighting function on a webpage and im using the jquery plugin for that. My code looks like this: var input = function() { var matchword = $('#searchbox').val(); if(matchword != "") { $('body').removeHighlight(); $('body').highlight($('#searchbox').val()); } } $(document).ready(function() { $('#searchbox').keyup(function() { setTimeout("input()", 2000); }); }); It works fine if there is not so large amount of data on the page. But in case of large amount of data on the page the whole process is slowing down which causes that inputbox is freezing untill the letter is hightlighted. So the typing is not smooth. I tryed to use a setTimeout but it seems doesnt help. Any ideas?

  • 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!

  • Javascript sliding (preferably jQuery)

    - by jwzk
    I am trying to think of the name of the plugin (or a plugin) that slides content in (up or down). So I have a hidden div, I click on one of the titles/header, it opens the hidden div, if I click on another header it hides the other visible div, and slides up or down the new one. I can't think of it for some reason.. anyone?

  • Retrieve a cross domain RSS(xml) through Javascript

    - by Ajay
    I have seen server side proxy workarounds for retrieving rss (xmls) from cross-domains. In fact this very question addressess my same problem but gives out a different solution. I have a constraint of do not use a proxy to retrieve rss feeds. And hence the Google AJAX Feed API solution also goes out of picture. Is there a client-only workaround for this problem. JSONP is the solution for requests that respond with JSON output. But here, I have RSS feeds which can respond with pure xml . How do I solve the problem.

  • Creating a Drop-Down Menu with Javascript

    - by iceteea
    Question about logics here: What's the most elegant way to make the menu appear/disappear onmouseover/onmouseout? See the following JsBin: http://jsbin.com/owayeb/edit#source The Menu is hidden by default. If the user moves his cursor above the Link the showme() function gets called. When the user moves his cursor away the hideme() functions gets called. How would I get the Menu to persist while the user moves his mouse away from the Link to above the Menu? Or is this all the wrong school of thought?
