Localstorage compatible IE6/7 with Addbehavior implementation

Production process I will not say, the program will be taken up under

Definefunction(){    if(' Localstorage 'inchWindowreturn; functionStorage () { This. Box = Document.body | | Document.getelementbytagname (' head ') [0] | |document.documentelement;  This.

Length (); } Storage.prototype.setItem=function(name,val) {if(name== ' Localstorage-map '){            Throw NewError ("This was localstorage in key [Localstorage-map] not use!")            return ; }        if( This. map.length==0){             This. Data.load (' Localstorage-map '); vardata = This. Data.getattribute (' Localstorage-map '); if(data!=NULL){                 This.

Calling programs

Localstorage.setitem (' value ', ' {askdjf:ddd} ')            localstorage.setitem (' name ', ' {ddddddd:ddd} ') Alert (            localstorage.getitem (' value ')) alert (            localstorage.getitem (' name '))            alert ( Localstorage.removeitem (' name '))            alert (localstorage.length);

I was just a simple test to be able, do not know where there are problems, looking at the twos!!!!!
