javascript - Changing link URL after every 5 visits -


what i'm trying accomplish following.

i have link on website, want change link after every 5 visits or "page refreshes" user , have loop.

so example visit site , download button links site called "www.site1.com". refresh site 5 times , download button link changes "www.site2.com". if refresh 6th time goes original.

i have not been able find searching through forums shows i'm trying accomplish here. experimenting window.onload , setinterval function changes link every 5 seconds. anyway transition every 5 seconds every 5 page visits?

window.onload = function() {   function changeurl(){     document.getelementbyid("link").href = "www.site1.com"; } setinterval(changeurl, 5000); }

you want use javascript localstorage or sessionstorage this. below example of code using localstorage

example

window.onload = function()  {        if (localstorage.visits)     {         //if value in local storage increase it's value         localstorage.visits = number(localstorage.visits) + 1;     }     else     {         //if value isn't in local storage set 0         localstorage.visits = 0;     }      //check if number of visits greater 5 , set link accordingly     if(localstorage.visits > 5)     {         document.getelementbyid("link").href = "www.site2.com";     }     else     {         document.getelementbyid("link").href = "www.site1.com";     } }

this work if browser supports localstorage. 1 thing note well, value not reset if close browser page. if want reset when page closed, that's sessionstorage for.

one more thing note: user can clear localstorage clearing browser data. if wanted more persistent don't believe there's javascript solution (feel free correct me if i'm wrong this!)
