帮我看看哪里出错了
$(window).on("load",function(){

console.log(value);
var oPin=$("<div>").addClass("pin").appendTo($("#main"));
var oBox=$("<div>").addClass("boc").appendTo($(oPin));
var oImg=$("img").attr("src","img/"+$(value).attr("src")).appendTo($(oBox));
});
waterfall();
}
})
})
function waterfall(){
var pin=$("#main>div");
var w=pin.eq(0).outerWidth();
var cols=Math.floor($(window).width()/w);

}
})
}

var scrollTop=$(window).scrollTop();
var documentH=$(window).height();
