如何从jQuery插件中提取值并设置为PHP变量？

Question

I am using a jQuery plugin called Stepy , to allow users to complete a 10-step form.

Sample form: http://jsfiddle.net/wvkfn/

My site is setup so the user can leave the form in the middle of a 'step', in order to complete other tasks, and I'd like to have a variable set, so that when they complete the task, it takes them back to the last step they were on.

Is there a way to pull the value of the 'current' step from the plugin? My first thought was that the plugin places a class called current-step on the title, and pull the number value from the title text that has that class set.

I'd then want to set that as a PHP variable, so I could set the task link to something like http://www.example.com/task.php?step=3 .

Any ideas on how to go about this?

Answer 1

Use the 'select' option stepy offers to register a callback when a tab is selected. In the callback use an asynchronous POST to your server to store the currently selected tab.

Sample:

$('#custom').stepy({
    ...,
    select: function(index){
        $.ajax({
            url: "saveCurrentStep?userID=1&step=" + index;
        });
    }
});

一种简单的解决方案是为当前步骤存储一个cookie ，或者您可以为每个步骤使用anchors URL例如步骤1 mysite.com/task.php#tsep1并从URL提取值
