//set to 301
the difference is that instead of sending a default 302, we are sending a 301, which is more seo and bot friendly. i would suspect that you would only use this in a case where the origination url is always going to goto the new target url, otherwise keep using the regular way.
There are cookies that exist that are not part of the browser. Even if you do a clear cookies from your browser of choice, these cookies still persist. these are cookies managed by adobe flash.
In an article mentioned here, a bunch of companies are being sued because of Quantcast, who basically recreated cookies using the flash system so that they could track users interactions with some big named sites.
So how do we remove those “zombie” cookies? Adobe provides a help page, but the page looks like its a demo when in reality it is your browser’s flash that you are controlling. The page of note is the web privacy one. You can go here to check it out.
What you will want to do is just do a delete all websites to clear your flash cookie cache. now you are back to being an anonymous user.
I was looking at Newegg‘s checkout procedure and it had this cool check box where you could either check all or check none, and then when you clicked on a sub checkbox it would check or uncheck the check all checkbox if it didn’t meet that condition. I re-created the code in JQuery so I could use it on one of my projects.
Ok, if you look at the markup, you’ll see that the table header has a checkbox with the id of ‘chkAll’. Then for all the items I have them with the class ‘chkbox’. It is important to note that the chkAll checkbox does NOT have the class ‘chkbox’.
The JQuery code:
var flag = $(this).is(':checked');
var flag = true;
flag = flag && $(this).is(':checked');
So how does it work? I make sure to call the functions only when the document is ready. Once that happens I attach a function to the clicking of the id ‘chkAll’. In this function I first check to see if the current chkAll checkbox is checked or not, if it is then I’m going to immediately make all the class ‘chkbox’ checkboxes to checked and vice versa.
The second function I have is if I happen to click one of the class ‘chkbox’ checkboxes, Again I attach a function to the click event. I use a JQuery expression .each- which is kinda like a foreach loop, which will loop through all the elements that satisfy my ‘chkbox’ class, I then create a variable that AND’s all the other element’s states. When it is done, I am able to determine if the chkAll checkbox should be checked or not.

I’ve always seen it done. Clearing the input field on focus.
JQuery seems to be pretty simple. Its just the syntax you have to get used to.
First the html markup
Notice that for each input field I have an id, name, and alt attribute
Next integrating JQuery
Next building the JQuery plugin
$.fn.clearSetFocus = function(iAttr)
We’re gonna create a namespace for ourselves. In my case, I named my function clearSetFocus. The $ creates a new JQuery object. you could also use jQuery(). So, I’ve created a new function named clearSetFocus and I’m taking in one parameter, called iAttr.
To actually attach this plugin to an element all I have to do is to call it.
Notice that I call the document.ready function before I add my plugin to the elements. I’ve found that if I don’t do that then the js could execute before the elements are loaded and make the script fail. So what I’ve done is create a new jQuery object for the element #newsName and attached the plugin clearSetFocus with the parameter alt.
Back to writing the plugin.
//name my function clearSetFocus
$.fn.clearSetFocus = function(iAttr)
if ($(this).val() == $(this).attr(iAttr))
//on blur - chained functionality
//get the value currently in the input
//replace the value with the alt value
The this refers to my element that I’ve attached the plugin to. so in this case the element #newsName. I attach the function focus() – which allows me to add a function to when the user focus’ on the element. In this case, my logic is simply, if my value is the same as my alt value, then clear it. on blur() – which means to navigate away from the element, my logic is if the value’s length is 0, but the alt value back in.
Couple things to note.
.val() – this allows me to either get the value associated with the element
.val(“test”) – allows me to set the value of the element
.attr(“id”) – allows me to retrieve the value of the attribute of the element. so if the markup was
