jQuery重定向传递数组

Question

On my site, users choose colors they want and after making their selections they proceed to the next page. Currently, every time they click on a color, I add it to a JavaScript array. When they are ready to go to the next page, I want to pass this array of colors so I can display their chosen colors on the next page. So my question is how can I accomplish this with jQuery or PHP?

Thanks.

You can pass the array in this way:

$.post('URL_Of_Next_Page', {'MyArray': actualArray});

To do the redirect, then you can do this:

window.location.replace("URL_Of_Next_Page");

I am not sure, but if you do the post before the redirect, then it might have the array, but I doubt it. You can either store the array in a session variable or you can do as safarov suggested and pass it via query parameters.

For the session approach

$_SESSION['MyArray'] = json_encode(actualArray);

Then to get it back:

actualArray = json_decode($_SESSION['MyArray']);

To get it JSONified to use as a string:

var actualArrayAsString = JSON.stringify(actualArray);
