js

//搭建model
function showHistory (showHistory){
    this.name = showHistory;
}
showHistory.prototype.saveTolStorage = function(){
    //将this写入本地存储
    //先将以前的数据取出来，然后在合并到数据中，在写回去
    var storage = window.localStorage.getItem('showHistory');
    storage = storage ? JSON.parse(storage) : [];
    storage.push(this);
    window.localStorage.setItem('showHistory',JSON.stringify(storage));
}
showHistory.selectByName = function(showHitory){
    var storage = window.localStorage.getItem(showHitory);
    storage = storage ? JSON.parse(storage) : [];
    return storage.some(function (v){
        return v.name === showHitory;
    });
}
