## 实现 ##

### dataTables赋值代码 ###

columns: [
                    { data: 'id' ,
                        "orderable" : false},
                    { data: 'goodsLocationNumber' },
                    { data: 'locationTypeName' ,
                        "orderable" : false},
                    { data: 'saveMaterialTypeName' ,
                        "orderable" : false},
                    { data: 'materielStatusName',
                        "orderable" : false},
                    { data: 'shelveName' ,
                        "orderable" : false},
                    { data: 'remark',
                        "orderable" : false }
                ],columnDefs: [{
                    //   指定第1列，从0开始，0表示第一列，1表示第二列……
                    "targets": 0,
                    "bSortable": false,
                    "render": function(data, type, row, meta) {
                        if (row.isSelected == 1){
                            return '<input type="checkbox" class="checkchild" onclick="childClick(this)" checked="checked" value="' + row.id + '" />'
                        }
                        return '<input type="checkbox" class="checkchild" onclick="childClick(this)" value="' + row.id + '" />'
                    }
                }],

### 完整初始化DataTables代码 ###

$(document).ready(function() {
        //获取下拉框的值，判断是否为空，不为空则是编辑，那么就要初始化dataTables
        var selected = $("#businessInitiator option:selected").val();
        if(selected!=""){
