jqueryUI sortable 可以用來(lái)進(jìn)行頁(yè)面拖拽布局，然而有一個(gè)小問(wèn)題就是拖拽后如何保存狀態(tài)。
工作中遇到了這個(gè)情況，遍把這個(gè)問(wèn)題記了下來(lái)，具體思路是：
利用拖拽stop后利用
var arr = $( ".sortable" ).sortable('toArray');
記錄拖拽后的id數(shù)組順序，然后把這個(gè)數(shù)組存起來(lái)，可以存cookie,數(shù)據(jù)庫(kù)，localstorage等，刷新頁(yè)面后讀取這個(gè)數(shù)組，然后進(jìn)行重新排序。
具體的代碼如下可直接復(fù)制運(yùn)行。本文將數(shù)組保存在localstorage里面。
