Jquery中的一些東西學習一下子,補充完善一下,畢竟有些時候沒有使用到
這個方式很有用,在使用bootstrap table的時候,選擇當前已經選擇的節點的事件中的ID的值
當前rows中有很多的數據,但是我只需要id這一值,這個時候進行操作就非常簡單的了。
$.map(data,function(item,index){return XXX}) //使用的总结: //把一个数组,按照新的方式进行组装返回,和原来的数组不一样。 //遍历data数组中的每个元素,并按照return中的计算方式 形成一个新的元素,放入返回的数组中 var b = $.map( [55,1,2], function( item,index ) { return { "label": item, "value": index } }); alert(b[0].label +" "+ b[0].value); //输出为 55 0
2.我的後台呢,是使用SpringMVC進行寫的,期間呢也是遇到了很多的問題,進行分頁處理的時候
使用了離線查詢,但是呢,我使用的是execute( )這個方法,傳入的session為代理類別的數據,不能再下面這個方法中進行轉換
導致錯誤了,我還百度了很久,最後才發現是這個問題導致的
/** * Get an executable instance of <literal>Criteria</literal>, * to actually run the query. */ public Criteria getExecutableCriteria(Session session) { impl.setSession( ( SessionImplementor ) session ); return impl; }
return (PageBean) getHibernateTemplate().executeWithNativeSession(new HibernateCallback() { public Object doInHibernate(Session session) throws HibernateException { Criteria criteria = detachedCriteria.getExecutableCriteria(session); ............................ }
{ "success": true, "message": null, "data": { "pageSize": 15, "rows": [ { "userName": "333", "userType": 333, "password": "333", "id": 11, "indexcode": "333" }, { "userName": "3", "userType": 333, "password": "333", "id": 5, "indexcode": "33333" } ....... ], "total": 17, "totalPage": 2, "page": 0, "hasPreviousPage": true, "hasNextPage": true, "lastPage": false, "firstPage": false } }
後台呢,我回傳的資料和格式不是按照BootStrap中的格式有點差別吧,反正就是不一樣
** * Created by JetWang on 2016/10/1. */ public class ActionResult { private boolean success; private String message; private Object data; public ActionResult(){ } public ActionResult(boolean success){ this(success, null, null); } ............ }
<%@ include file="./common/common.jsp"%> //什么公用的bootstrapt ,JQuery啊之类的引用放进去处理了 <script src="<%=baseUrl%>/libs/bootstrap-table/dist/bootstrap-table.js" type="text/javascript"></script> <script src="<%=baseUrl%>/libs/bootstrap-table/dist/bootstrap-table-locale-all.js" type="text/javascript"> </script> <link rel="stylesheet" href="<%=baseUrl%>/libs/bootstrap-table/dist/bootstrap-table.css" type="text/css"> //这里就是容器中放置table的 <div class="container"> <table id="table" data-url="/cms/UserInfo/userInfoPage">//使用的路径,后台请求的URL </table> </div>
來看看前端的效果吧
jQuery(document).ready(function() { //这里你可以使用各种法师,也可以使用seajs前端模块化工具 下面放置我们的js代码就好了 });
這裡你可以進行重寫哦~~ ,extentd進行重新的覆蓋!
BootstrapTable.DEFAULTS = { classes: 'table table-hover', locale: undefined, height: undefined, undefinedText: '-', sortName: undefined, sortOrder: 'asc', sortStable: false, striped: false, columns: [[]], data: [], dataField: 'rows', method: 'get', url: undefined, ajax: undefined, cache: true, contentType: 'application/json;charset=UTF-8',//这里我就加了个utf-8 dataType: 'json', ajaxOptions: {}, queryParams: function (params) {//这个是设置查询时候的参数,我直接在源码中修改过,不喜欢offetset 我后台用的 是pageNo. 这样处理就比较的满足我的要求,其实也可以在后台改,麻烦! return params; }, queryParamsType: 'limit', // undefined (这里是根据不同的参数,选择不同的查询的条件) responseHandler: function (res) {//这里我查看源码的,在ajax请求成功后,发放数据之前可以对返回的数据进行处理,返回什么部分的数据,比如我的就需要进行整改的! return res; }, pagination: false, onlyInfoPagination: false, sidePagination: 'client', // client or server totalRows: 0, // server side need to set pageNumber: 1, pageSize: 10, pageList: [10, 25, 50, 100], paginationHAlign: 'right', //right, left paginationVAlign: 'bottom', //bottom, top, both paginationDetailHAlign: 'left', //right, left paginationPreText: '‹', paginationNextText: '›', search: false, searchOnEnterKey: false, strictSearch: false, searchAlign: 'right', selectItemName: 'btSelectItem', showHeader: true, showFooter: false, showColumns: false, showPaginationSwitch: false,//展示页数的选择? showRefresh: false, showToggle: false, buttonsAlign: 'right', smartDisplay: true, escape: false, minimumCountColumns: 1, idField: undefined, uniqueId: undefined, cardView: false, detailView: false, detailFormatter: function (index, row) { return ''; }, trimOnSearch: true, clickToSelect: false, singleSelect: false, toolbar: undefined, toolbarAlign: 'left', checkboxHeader: true, sortable: true, silentSort: true, maintainSelected: false, searchTimeOut: 500, searchText: '', iconSize: undefined, buttonsClass: 'default', iconsPrefix: 'glyphicon', // glyphicon of fa (font awesome) icons: { paginationSwitchDown: 'glyphicon-collapse-down icon-chevron-down', paginationSwitchUp: 'glyphicon-collapse-up icon-chevron-up', refresh: 'glyphicon-refresh icon-refresh', toggle: 'glyphicon-list-alt icon-list-alt', columns: 'glyphicon-th icon-th', detailOpen: 'glyphicon-plus icon-plus', detailClose: 'glyphicon-minus icon-minus' }, customSearch: $.noop, customSort: $.noop, rowStyle: function (row, index) { return {}; }, rowAttributes: function (row, index) { return {}; }, footerStyle: function (row, index) { return {}; }, onAll: function (name, args) { return false; }, onClickCell: function (field, value, row, $element) { return false; }, onDblClickCell: function (field, value, row, $element) { return false; }, onClickRow: function (item, $element) { return false; }, onDblClickRow: function (item, $element) { return false; }, onSort: function (name, order) { return false; }, onCheck: function (row) { return false; }, onUncheck: function (row) { return false; }, onCheckAll: function (rows) { return false; }, onUncheckAll: function (rows) { return false; }, onCheckSome: function (rows) { return false; }, onUncheckSome: function (rows) { return false; }, onLoadSuccess: function (data) { return false; }, onLoadError: function (status) { return false; }, onColumnSwitch: function (field, checked) { return false; }, onPageChange: function (number, size) { return false; }, onSearch: function (text) { return false; }, onToggle: function (cardView) { return false; }, onPreBody: function (data) { return false; }, onPostBody: function () { return false; }, onPostHeader: function () { return false; }, onExpandRow: function (index, row, $detail) { return false; }, onCollapseRow: function (index, row) { return false; }, onRefreshOptions: function (options) { return false; }, onRefresh: function (params) { return false; }, onResetView: function () { return false; } };
看看上面的自己也基本上曉得怎麼去,書寫了!其實之前我根本不敢這麼玩,只不過之前實習過程中導師教過我怎麼去玩,所以我才敢,我相信,我可以好好的 玩好這些東西的!
function initTable() { $table.bootstrapTable({ striped: true, //表格显示条纹 pagination: true, //启动分页 pageSize: 15, //每页显示的记录数 pageNumber:1, //当前第几页 pageList: [10, 15, 20, 25], //记录数可选列表 search: false, //是否启用查询 showColumns: true, //显示下拉框勾选要显示的列 showRefresh: true, //显示刷新按钮 sidePagination: "server", //表示服务端请求 //设置为undefined可以获取pageNumber,pageSize,searchText,sortName,sortOrder //设置为limit可以获取limit, offset, search, sort, order responseHandler:function(res){ //远程数据加载之前,处理程序响应数据格式,对象包含的参数: 我们可以对返回的数据格式进行处理 //在ajax后我们可以在这里进行一些事件的处理 return res.data; }, queryParamsType : "undefined", queryParams: function queryParams(params) { //设置查询参数 var param = { //这里是在ajax发送请求的时候设置一些参数 params有什么东西,自己看看源码就知道了 pageNo: params.pageNumber, pageSize: params.pageSize }; return param; }, onLoadSuccess: function(data){ //加载成功时执行 alert("加载成功"+data); }, onLoadError: function(){ //加载失败时执行 layer.msg("加载数据失败", {time : 1500, icon : 2}); }, height: getHeight(), columns: [ { field: 'state', checkbox: true, align: 'center', valign: 'middle' }, { title: 'ID', field: 'id', align: 'center', valign: 'middle' }, { field: 'userName', title: 'UserName', sortable: true, footerFormatter: totalNameFormatter, align: 'center' }, { field: 'userType', title: 'UserType', sortable: true, align: 'center' }, { field: 'password', title: 'UserPass', sortable: true, align: 'center' },{ field: 'indexcode', title: 'Indexcode', sortable: true, align: 'center' },{ field: 'operate', title: 'Item Operate', align: 'center', events: operateEvents, formatter: operateFormatter } ] });
formatter:
The context (this) is the column Object. The column ter. value: the field value. row: the row record data. index: the row index.footerFormatter :
The context (this) is the column Object. The function, take one parameter:data: Array of . The function, take one parameter:
data: Array of . the function should return a string with the text to show in the footer cell.都是對於當前列進行處理顯示
如下就是增加了兩個按鈕在一個單元格中
function operateFormatter(value, row, index) { return [ '<a class="like" href="javascript:void(0)" title="Like">', '<i class="glyphicon glyphicon-heart"></i>', '</a> ', '<a class="remove" href="javascript:void(0)" title="Remove">', '<i class="glyphicon glyphicon-remove"></i>', '</a>' ].join(''); }
<%--{ title: '操作', field: 'id', align: 'center', formatter:function(value,row,index){ var e = '<a href="#" rel="nofollow" target="_blank" mce_href="#" rel="nofollow" target="_blank" onclick="edit(\''+ row.id + '\')">编辑</a> '; var d = '<a href="#" rel="nofollow" target="_blank" mce_href="#" rel="nofollow" target="_blank" onclick="del(\''+ row.id +'\')">删除</a> '; return e+d; 也可以这样处理事件的 } }--%>
Example code:
{ field: 'operate', title: 'Item Operate', align: 'center', events: operateEvents, formatter: operateFormatter } function operateFormatter(value, row, index) { return [ '<a class="like" href="javascript:void(0)" title="Like">', '<i class="glyphicon glyphicon-heart"></i>', '</a> ', '<a class="remove" href="javascript:void(0)" title="Remove">', '<i class="glyphicon glyphicon-remove"></i>', '</a>' ].join(''); } window.operateEvents = { 'click .like': function (e, value, row, index) { alert('You click like action, row: ' + JSON.stringify(row)); }, 'click .remove': function (e, value, row, index) { $table.bootstrapTable('remove', { field: 'id', values: [row.id] }); } };
$('#table').bootstrapTable({ onEventName: function (arg1, arg2, ...) { // ... } }); $('#table').on('event-name.bs.table', function (e, arg1, arg2, ...) { // ... }); //这个名字文档中很多! onAll all.bs.table name, args Fires when all events trigger, the parameters contain: name: the event name, args: the event data.
//The calling method syntax: $('#table').bootstrapTable('method', parameter); //1 当前选择选的框框的id getSelections none Return selected rows, when no record selected, an empty array will return. //2.全选 getAllSelections none Return all selected rows contain search or filter, when no record selected, an empty array will return. $table.on('all.bs.table', function (e, name, args) { console.log(name, args); }); //3.删除 前台的数据,不需要从后台重新加载 remove params Remove data from table, the params contains two properties: field: the field name of remove rows. values: the array of values for rows which should be removed.
一個刪除的按鈕,刪除所有的選擇的事件!是不是很好呢!
function getIdSelections() { return $.map($table.bootstrapTable('getSelections'), function (row) { return row.id }); } $remove.click(function () { var ids = getIdSelections(); $table.bootstrapTable('remove', { field: 'id', values: ids }); $remove.prop('disabled', true); });
