A user on the SO forums asked about the return values inside jQuery's scrollTop(value). Because the documentation does not specify what this would be I thought they made an error. However, upon investigation I found that the second returned item is the current scrollTop position. But I can't figure out what the first is.
You can see in the code example here that when scrolling the first value is always zero, the second is the current scrollTop.
1. What is the first value?
2. Is this documented anywhere?
3. Is it often the case that when jQuery has a getter and setter method with the same name that the setter can, by means of a return function, use the getter?
Code in case links go dark:
$(window).scroll(function(){
$('body').scrollTop(function(i, v){
console.log(i +' '+ v);// (v == $('body').scrollTop())});});
OK, I have a show/hide script on my website for a sidebar (social network buttons) and it would be nice that the status of the sidebar stays the same, even after page reload/going to another page on the site.
I tried do this with a cookiescript that I found here on jQuery:
/** * Create a cookie with the given name and value and other optional parameters. * * @example $.cookie('the_cookie', 'the_value'); * @desc Set the value of a cookie. * @example $.cookie('the_cookie', 'the_value', { expires: 7, path: '/', domain: 'jquery.com', secure: true }); * @desc Create a cookie with all available options. * @example $.cookie('the_cookie', 'the_value'); * @desc Create a session cookie. * @example $.cookie('the_cookie', null); * @desc Delete a cookie by passing null as value. Keep in mind that you have to use the same path and domain * used when the cookie was set. * * @param String name The name of the cookie. * @param String value The value of the cookie. * @param Object options An object literal containing key/value pairs to provide optional cookie attributes. * @option Number|Date expires Either an integer specifying the expiration date from now on in days or a Date object. * If a negative value is specified (e.g. a date in the past), the cookie will be deleted. * If set to null or omitted, the cookie will be a session cookie and will not be retained * when the the browser exits. * @option String path The value of the path atribute of the cookie (default: path of page that created the cookie). * @option String domain The value of the domain attribute of the cookie (default: domain of page that created the cookie). * @option Boolean secure If true, the secure attribute of the cookie will be set and the cookie transmission will * require a secure protocol (like HTTPS). * @type undefined * * @name $.cookie * @cat Plugins/Cookie * @author Klaus Hartl/klaus.hartl@stilbuero.de */
/** * Get the value of a cookie with the given name. * * @example $.cookie('the_cookie'); * @desc Get the value of a cookie. * * @param String name The name of the cookie. * @return The value of the cookie. * @type String * * @name $.cookie * @cat Plugins/Cookie * @author Klaus Hartl/klaus.hartl@stilbuero.de */
jQuery.cookie = function(name, value, options) { if (typeof value != 'undefined') { // name and value given, set cookie options = options || {}; if (value === null) { value = ''; options.expires = -1; } var expires = ''; if (options.expires && (typeof options.expires == 'number' || options.expires.toUTCString)) { var date; if (typeof options.expires == 'number') { date = new Date(); date.setTime(date.getTime() + (options.expires * 24 * 60 * 60 * 1000)); } else { date = options.expires; } expires = '; expires=' + date.toUTCString(); // use expires attribute, max-age is not supported by IE } // CAUTION: Needed to parenthesize options.path and options.domain // in the following expressions, otherwise they evaluate to undefined // in the packed version for some reason... var path = options.path ? '; path=' + (options.path) : ''; var domain = options.domain ? '; domain=' + (options.domain) : ''; var secure = options.secure ? '; secure' : ''; document.cookie = [name, '=', encodeURIComponent(value), expires, path, domain, secure].join(''); } else { // only name given, get cookie var cookieValue = null; if (document.cookie && document.cookie != '') { var cookies = document.cookie.split(';'); for (var i = 0; i < cookies.length; i++) { var cookie = jQuery.trim(cookies[i]); // Does this cookie string begin with the name we want? if (cookie.substring(0, name.length + 1) == (name + '=')) { cookieValue = decodeURIComponent(cookie.substring(name.length + 1)); break; } } } return cookieValue; } };
First of, sorry for my bad English, but I'm from Belgium. Second, I know close to nothing about jQuery, nor Javascript (so I'm only familiar with HTML and CSS)
I did, however, put this site together, currently version2 (don't be scared, that text is in Dutch )
As you might see in the code, I use fancybox for my photo albums. I've had no problems with it so far, but now I'm working on version3 it gives me some problems. I'll explain why.
I am trying to implement a script that allows a visitor to hide the buttons on the left (demo; still in progress) but when I implement this script it won't let me use fancybox anymore (it will link directly to the image, not to the image in fancybox)
What's in the code:
For fancybox these are the scripts (youtube.js is a 'custom' script for youtube clips in fancybox)
