When cross-domain, use a URL to pass data and take values.

Many times, we often encounter cross-domain situations, such as a.html's data to be used in b.html.

Then, we can pass the data through the URL to achieve the way:

Like my data on the a.html page: codeid=2 Username=lee Checkname=kay want to pass the URL to the b.html page

Well, we can do this in the URL of the b.html page B.html?codeid=2&username=lee&checkname=kay

Note that there is a need to use "&" to connect multiple data.

Then, we can go to the b.html page to take the value operation.

1 functionTransferurlqueryvariables () {2     varSearch =Window.location.search,3 Query,4 VARs,5VarMap = {};6 7     if(!search | | Search.length < 2) {8         returnVarMap;9     }Ten  Onequery = search.substring (1); AVARs = Query.split (' & ')); -  -      for(vari = 0, pair, length = vars.length; i < length; i++) { thePair = vars[i].split (' = ')); -Varmap[decodeuricomponent (pair[0])] = decodeURIComponent (pair[1]); -     } -      +     returnVarMap; -}

In this way, it is no problem to take values across domains.
