//拖拽组件设置
var gridly_set = {
//reordering拖拽前回调函数，reordered拖拽后回调函数
callbacks:{ reordering: reordering , reordered: reordered },
//间距
gutter:60,
//显示列数
columns:6
};
//加载拖拽组件
$('#gridly').gridly(gridly_set);
//拖拽前回调
function reordering(){
console.log('reordering');
}
//拖拽后回调
function reordered(){
console.log('reordered');
//隔100ms 防止在拖拽放下那一瞬间 返回的left top不准确
setTimeout(get_user_id_data,100);
}
//获取user_ids 并排序 且 ajax提交
function get_user_id_data(){
var dom = $('#gridly div');
var tmp = {};
// 列数的权重 必须保证此数字大于每行的最大宽度
// 其实可以用columns*(gutter+base_width) 来计算 但鉴于columns不经常变 没必要这样写
var col_base_num = 10000;
dom.each(function(){
var self = $(this);
var left_num = self.css('left').replace(/px/,'');
var top_num = self.css('top').replace(/px/,'');
//加1 保证top大于0
var top_tmp = parseInt(top_num) + 1;
//权重 = left + (top+1)*col_base_num
var weight = parseInt(left_num) + (top_tmp*col_base_num);
var user_id = self.attr('user_id');
tmp[weight] = user_id;
});
//利用对象本身对key的排序功能 实现排序
var i;
var arr = [];
for(i in tmp){
var r = tmp[i];
arr.push(r);
}
//排序后的数组
console.log(arr);
}
</script>
</body>

jquery 以及 jquery.gridly.js 放至相对目录
效果:
