场景
在进行编辑时DataTables中第一列的checkbox回显默认选中。
效果
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dataTablesvar selected = $("#businessInitiator option:selected").val();if(selected!=""){var t = $('#example').DataTable({"language": {"processing": "处理中...","lengthMenu": "显示 _MENU_ 项结果","zeroRecords": "没有匹配结果","info": "显示第 _START_ 至 _END_ 项结果，共 _TOTAL_ 项","infoEmpty": "显示第 0 至 0 项结果，共 0 项","infoFiltered": "(由 _MAX_ 项结果过滤)","infoPostFix": "","search": "搜索:","searchPlaceholder": "搜索...","url": "","emptyTable": "表中数据为空","loadingRecords": "载入中...","infoThousands": ",","paginate": {"first": "首页","previous": "上页","next": "下页","last": "末页"},"aria": {paginate: {first: '首页',previous: '上页',next: '下页',last: '末页'},"sortAscending": ": 以升序排列此列","sortDescending": ": 以降序排列此列"},"decimal": "-","thousands": "."},"processing": true,"searching" : false,"pageLength": 100,"serverSide": true,"columnDefs": [ {"searchable": false,"orderable": false,"targets": "_all",}],"dom": '<"top">rt<"bottom"flpi><"clear">',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 + '" />'}}],"ajax": function (data, callback, setting) {data.editActionId = $("#refundOrderId").val();data.selected=selected;$.ajax({type: 'POST',url: "/busGoodsLocation/getRejectsLocationsList",cache: false, //禁用缓存//async: true,data: JSON.stringify(data), //传入组装的参数contentType: "application/json",dataType: "json",success: function (result) {callback(result);}})}});}});
