I have a variable $sitedata, an object, that is structured like:
{
'fname':null,
'lname':null,
moduleLevel: {
bPassed: null,
bContentComplete: null,
iNumAttempts: null,
dDateStart: month + "/" + day + "/" + year,//"6/25/2007",
dDateEnd: null,
sTestTaken: null,
sTestPassed: null,
sPageViewed: null
},
lessonLevel:{
_0_0:{
iLessonRef: 0,
iTopicRef: 0,
bIsDone: 0,
sInlineQuiz: '0',
sPageRef: 0
}
}
}
Now, to get the object into a cookie we need to convert it to a querysting,
like:
objectToQueryString($sitedata,"&")
which will return something like:
fname=benjamin&lname=sterling etc....
If used like below:
$.cookie('myCookie', objectToQueryString(myObject,"&"));
Now our cookie is set, now we want to grab it again:
var tempSiteData = $.cookie('myCookie');
now we turn our querysting (fname=benjamin&lname=sterling)
myObject = queryStringToObject(tempSiteData);
into:
{
fname :'benjamin',
lname :'sterling',
etc...
}
Let me know if you understand.
