上边是已经封装好的tree,感谢某大神 原创出处:http://www.cnblogs.com/landeanfen/,
我之前踩了不会少坑,因为毕设要做,所以自己摸索了下,
看图,我使用后效果
这个是需要引入,这里通过ajax获取后台值,但需要转为json一次,看下边data
<link href="../static/css/bootstrap-table.min.css" rel="stylesheet" type="text/css"/> <link href="../static/css/bootstrap.css" rel="stylesheet" type="text/css"/> <script type="text/javascript" src="../static/js/jquery-3.2.1.min.js"></script> <script type="text/javascript" src="../static/js/bootstrap.min.js"></script> <script type="text/javascript" src="../static/js/bootstrap-table.min.js"></script> <script type="text/javascript" src="../static/js/上边的.js"></script>
我现在分享出自己的代码,
var tree; $(function () { var oTable = new TableInit(); oTable.Init(); $("#expandAllTree").on('click', function () { if ($("#expandAllTree").val() == '展开所有') { $('#tree_table').bootstrapTable("expandAllTree")//展开\ $("#expandAllTree").val('折叠所有') } else { $('#tree_table').bootstrapTable("collapseAllTree")//折叠 $("#expandAllTree").val('展开所有') } }) }); var TableInit = function () { var oTableInit = new Object(); //初始化Table oTableInit.Init = function () { $.ajax({ url: '/fault_list', method: 'get', dataType: 'json', async: false, success: function (data) { tree = JSON.stringify(data) } }) $('#tree_table').bootstrapTable({ class: 'table table-hover table-bordered', data: eval(tree), pagination: false, treeView: true, striped: true, //是否各行渐变色 bordered: true, //是否显示边框 treeId: "id", treeField: "events", columns: [{ align: 'center', title: '编号', formatter: function (value, row, index) { return index + 1; } }, { field: 'id', visible: false, }, { align: 'left', field: 'events', title: '事件', editable: { type: 'text', validate: function (data, value, row) { if ($.trim(data) == '') return '请输入事件'; } } }, { align: 'center', field: 'type', title: '事件类型', // editable: { // type: 'select', // source: [{value: "T", text: "T"}, {value: "M", text: "M"}, {value: "X", text: "X"}] // // } }, { align: 'center', field: 'describe', title: '描述', editable: { type: 'text', validate: function (data) { if ($.trim(data) == '') return '请输入描述'; } } }, { align: 'center', field: 'signature', title: '唯一特征码', }, { align: 'right', title: '操作', formatter: function (value, row) { a = '<button class="btn btn-primary" data-toggle="modal" data-target="#addeventModal"' + ' onclick="update_top(' + row.id + ')" >添加子事件</button> ' if (row.type == 'X') { a = "" } b = '<button class="btn btn-danger" data-toggle="modal" data-target="#delModal"' + ' onclick="delete_eve(' + row.id + ')"' + ' >删除</button> ' return a + b } }, ], onEditableSave: function (field, row, oldValue, $el) { $.ajax({ type: "POST", url: "/fault_upd/", data: row, success: function (data) { if (data == "ok") { toastr.success('修改成功'); } else { toastr.error('修改失败'); } }, error: function () { toastr.error('后台error'); }, }); } }); } return oTableInit; };
看看后台
后台使用python,django实现,前台要什么就传什么,自己要去处理下parentId,,它是根据parentId处理树的,而且树不支持分页的,其他也就没什么了,有问题可以评论
