easyui datagrid表格多行上下移动排序的问题。。。

Question

jqueryeasyuidatagrid排序表格行排序

Answer 1

jquery 好像有类似的sort 插件。

Answer 2

主要是datagrid的每行是分段的，我晕倒。你看代码：
$row.each(function(){
                        var prev = $(this).prev();
                        prev.length && $(this).insertBefore(prev);
                });

自己搞定了！
方法1（不会改变行索引，动态添加行至首行会有问题）：
function move(isUp) {
        var selections = dt.datagrid("getSelections");
        if(selections.length == 0){
                return;
        }
        if(selections.length > 1){
                //$.message.show("一次只能移动一条数据。","warning",2);
                //return;
        }
        var length = dt.datagrid("getRows").length;
    var $view = $('div.datagrid-view');
    if(isUp){
            for(var i = 0; i < selections.length; i++){
                        var index = dt.datagrid('getRowIndex',selections);
                        var $row = $view.find('tr[datagrid-row-index=' + index + ']').eq(1);
                        if($row.index() <= 0) return;
                        $row.insertBefore($row.prev());
                }
    }else{
            for(var i = selections.length - 1; i >= 0; i--){
                        var index = dt.datagrid('getRowIndex',selections);
                        var $row = $view.find('tr[datagrid-row-index=' + index + ']').eq(1);
                        if($row.index() >= length-1) return;
                        $row.insertAfter($row.next());
                }
    }
}方法2：
function move1(isUp) {
        var selections = dt.datagrid("getSelections");
        if(selections.length == 0){
                return;
        }
        if(selections.length > 1){
                //$.message.show("一次只能移动一条数据。","warning",2);
                //return;
        }
        var length = dt.datagrid("getRows").length;
        for(var i = 0; i < selections.length; i++){
                var index ,$i,newIndex;
                if(isUp){
                        $i = i;
                        index = dt.datagrid('getRowIndex',selections[$i]);
                        if(index <= 0)return;
                        newIndex = index - 1;
                }else{
                        var $i = selections.length-1-i;
                        index = dt.datagrid('getRowIndex',selections[$i]);
                        if(index >= length-1)return;
                        newIndex = index + 1;
                }
                dt.datagrid("deleteRow",index);
                dt.datagrid("insertRow",{index : newIndex,row:selections[$i]});
                dt.datagrid("selectRow",newIndex);
                
        }
}
