Detailed explanation of JS table component artifact bootstrap table (basic version)

Bootstrap table table component artifact of JS component series [Final Chapter]

Bootstrap table table component artifact of JS component series [2. Parent-child table and row and column ordering]

Bootstrap Table is a lightweight and feature-rich data display in the form of a table. It supports radio selection, checkbox, sorting, paging, show/hide columns, fixed title scrolling table, responsive design, and Ajax loading. JSON data, click-sorted columns, card views, and more. So this article will introduce to you the Bootstrap table component artifact of the JS component series [Final Chapter], let’s learn together!

1. Effect display

1. Table row style

For example, we have a requirement to display an order page. Orders with different statuses display different colors, as shown in the figure:


2. Table inline editing

During the first article, some garden friends asked the blogger whether the effect of in-line editing can be supported, and the answer is yes. Let’s take a look at the effect first:

Before editing


Click on a cell data


After editing


3. Merge table rows and columns

Bloggers think that the need to merge rows and columns is very common, especially when making page reports. Let’s take a look at the effect first:

The current page is not fully displayed, click to enter and take a look. How about it? The effect is not bad.

4. Export table data

Regarding table data export, bootstrap table supports three modes of export: basic, all, and selected. That is, the current page data export, all data export, and selected data export. It also supports exporting multiple types of files, such as common excel, xml, json and other formats.

Export current page to excel


Export all data in the table

Export selected row data

As for the export of other types of files, it is basically the same as excel, so the effects will not be displayed.

2. Table row style code example

Regarding the style setting of table rows, the others are one of its most basic functions. Why put it in the third article? It’s because the blogger thinks this feature may be useful everywhere. Of course, the effect is not difficult. You can also use jQuery to set the background color of tr. However, the blogger feels that since bootstrap table provides a mechanism to set the background color of rows, why don't we use its built-in API. Let's see how to do it.

When initializing the form

     //初始化Table
$('#tb_order').bootstrapTable({
url: '/TableStyle/GetOrder', //请求后台的URL(*)
method: 'get', //请求方式(*)
//toolbar: '#toolbar', //工具按钮用哪个容器
striped: true, //是否显示行间隔色
cache: false, //是否使用缓存,默认为true,所以一般情况下需要设置一下这个属性(*)
pagination: true, //是否显示分页(*)
sortable: false, //是否启用排序
sortOrder: "asc", //排序方式
queryParams: oTableInit.queryParams,//传递参数(*)
sidePagination: "server", //分页方式:client客户端分页,server服务端分页(*)
pageNumber: 1, //初始化加载第一页,默认第一页
pageSize: 10, //每页的记录行数(*)
pageList: [10, 25, 50, 100], //可供选择的每页的行数(*)
search: true, //是否显示表格搜索,此搜索是客户端搜索,不会进服务端,所以,个人感觉意义不大
strictSearch: true,
showColumns: true, //是否显示所有的列
showRefresh: true, //是否显示刷新按钮
minimumCountColumns: 2, //最少允许的列数
clickToSelect: true, //是否启用点击选中行
height: 500, //行高,如果没有设置height属性,表格自动根据记录条数觉得表格高度
uniqueId: "ID", //每一行的唯一标识,一般为主键列
showToggle: true, //是否显示详细视图和列表视图的切换按钮
cardView: false, //是否显示详细视图
detailView: false, //是否显示父子表
rowStyle: function (row, index) {
//这里有5个取值代表5中颜色['active', 'success', 'info', 'warning', 'danger'];
var strclass = "";
if (row.ORDER_STATUS == "待排产") {
strclass = 'success';//还有一个active
}
else if (row.ORDER_STATUS == "已删除") {
strclass = 'danger';
}
else {
return {};
}
return { classes: strclass }
},
columns: [{
checkbox: true
}, {
field: 'ORDER_NO',
title: '订单编号'
}, {
field: 'ORDER_TYPE',
title: '订单类型'
}, {
field: 'ORDER_STATUS',
title: '订单状态'
}, {
field: 'REMARK',
title: '备注'
}, ]
}); 
Copy after login

In fact, the key point lies in this parameter:

       rowStyle: function (row, index) {
//这里有5个取值代表5中颜色['active', 'success', 'info', 'warning', 'danger'];
var strclass = "";
if (row.ORDER_STATUS == "待排产") {
strclass = 'success';//还有一个active
}
else if (row.ORDER_STATUS == "已删除") {
strclass = 'danger';
}
else {
return {};
}
return { classes: strclass }
}, 
Copy after login

bootstrap table支持5中表格的行背景色,分别是'active', 'success', 'info', 'warning', 'danger'这五种,至于每种对应的背景颜色,将代码运行起来就可看到。关于这个方法的返回值,博主第一次用的时候也研究了好久,按照bootstrap table的规则,必须返回一个json格式的对象型如: { classes: strclass } 。

三、表格行内编辑代码示例

关于表格行内编辑,需要使用bootstrap table扩展的几个js文件。

1、引入额外的js文件

<link rel="stylesheet" href="//rawgit.com/vitalets/x-editable/master/dist/bootstrap3-editable/css/bootstrap-editable.css">
<script src="//rawgit.com/vitalets/x-editable/master/dist/bootstrap3-editable/js/bootstrap-editable.js"></script>
<script src="~/Content/bootstrap-table/extensions/editable/bootstrap-table-editable.js"></script> 
Copy after login

2、在cshtml页面定义表格时,添加两个属性

<table id="tb_departments">
<thead>
<tr>
<th data-field="Name" data-editable="true">部门名称</th>
<th data-field="ParentName">上级部门</th>
<th data-field="Level" data-editable="true">部门级别</th>
<th data-field="Desc" data-editable="true">描述</th>
</tr>
</thead>
</table> 
Copy after login

如果是在js里面初始化,写法如下:

{
field: "name",
title: "名称",
editable:true
}
Copy after login

3、在js里面初始化表格的时候注册编辑保存的事件

$('#tb_departments').bootstrapTable({
url: '/Editable/GetDepartment', //请求后台的URL(*)
method: 'get', //请求方式(*)
toolbar: '#toolbar', //工具按钮用哪个容器
striped: true, //是否显示行间隔色
cache: false, //是否使用缓存,默认为true,所以一般情况下需要设置一下这个属性(*)
pagination: true, //是否显示分页(*)
sortable: false, //是否启用排序
sortOrder: "asc", //排序方式
queryParams: oTableInit.queryParams,//传递参数(*)
sidePagination: "server", //分页方式:client客户端分页,server服务端分页(*)
pageNumber: 1, //初始化加载第一页,默认第一页
pageSize: 10, //每页的记录行数(*)
onEditableSave: function (field, row, oldValue, $el) {
$.ajax({
type: "post",
url: "/Editable/Edit",
data: { strJson: JSON.stringify(row) },
success: function (data, status) {
if (status == "success") {
alert("编辑成功");
}
},
error: function () {
alert("Error");
},
complete: function () {
}
});
}
}); 
Copy after login

重点还是看看这个事件的处理方法  

 onEditableSave: function (field, row, oldValue, $el) {
$.ajax({
type: "post",
url: "/Editable/Edit",
data: { strJson: JSON.stringify(row) },
success: function (data, status) {
if (status == "success") {
alert("编辑成功");
}
},
error: function () {
alert("Error");
},
complete: function () {
}
});
} 
Copy after login

对应的方法里面需要自己处理保存的逻辑。四个参数field, row, oldValue, $el分别对应着当前列的名称、当前行数据对象、更新前的值、编辑的当前单元格的jQuery对象。

四、表格行列合并代码示例

表格的行列合并功能不用引用其他的js文件,只需要在cshtml页面使用table的colspan和rowspan即可实现。

1、cshtml页面

<table id="tb_report">
<thead>
<tr>
<th colspan="4" data-valign="middle" data-align="center">第一季度</th>
<th colspan="4" data-valign="middle" data-align="center">第二季度</th>
<th colspan="4" data-valign="middle" data-align="center">第三季度</th>
<th colspan="4" data-valign="middle" data-align="center">第四季度</th>
<th data-field="TotalCount" rowspan="2" data-valign="middle" data-align="center">年度汇总</th>
</tr>
<tr>
<th data-field="JanCount" data-align="center">一月</th>
<th data-field="FebCount" data-align="center">二月</th>
<th data-field="MarCount" data-align="center">三月</th>
<th data-field="FirstQuarter" data-align="center">第一季度</th>
<th data-field="AprCount" data-align="center">四月</th>
<th data-field="MayCount" data-align="center">五月</th>
<th data-field="JunCount" data-align="center">六月</th>
<th data-field="SecondQuarter" data-align="center">第二季度</th>
<th data-field="JulCount" data-align="center">七月</th>
<th data-field="AguCount" data-align="center">八月</th>
<th data-field="SepCount" data-align="center">九月</th>
<th data-field="ThirdQuarter" data-align="center">第三季度</th>
<th data-field="OctCount" data-align="center">十月</th>
<th data-field="NovCount" data-align="center">十一月</th>
<th data-field="DecCount" data-align="center">十二月</th>
<th data-field="ForthQuarter" data-align="center">第四季度</th>
</tr>
</thead>
</table> 
Copy after login

2、js初始化并无特殊

$('#tb_report').bootstrapTable({
url: '/GroupColumns/GetReport', //请求后台的URL(*)
method: 'get', //请求方式(*)
toolbar: '#toolbar', //工具按钮用哪个容器
striped: true, //是否显示行间隔色
cache: false, //是否使用缓存,默认为true,所以一般情况下需要设置一下这个属性(*)
pagination: true, //是否显示分页(*)
sortOrder: "asc", //排序方式
queryParams: oTableInit.queryParams,//传递参数(*)
sidePagination: "server", //分页方式:client客户端分页,server服务端分页(*)
pageNumber: 1, //初始化加载第一页,默认第一页
pageSize: 10, //每页的记录行数(*)
pageList: [10, 25, 50, 100], //可供选择的每页的行数(*)
}); 
Copy after login

怎么样,有没有很简单。当然,有人说了,你都可以不用js初始化,直接在cshtml里面用table的属性去设置url、分页等信息。确实,如果我们看过它的api,会发现它初始化的每一个属性都对应一个table的属性。型如

如果你的表格没有一些特殊的事件需要处理,这样是完全没有问题的。

五、表格数据导出代码示例

表格数据的导出功能也需要一些扩展的js支持。

1、引入额外的js文件

<script src="~/Content/bootstrap-table/extensions/export/bootstrap-table-export.js"></script>
<script src="//rawgit.com/hhurz/tableExport.jquery.plugin/master/tableExport.js"></script>
Copy after login

2、js初始化的时候

 $('#tb_departments').bootstrapTable({
url: '/Export/GetDepartment', //请求后台的URL(*)
method: 'get', //请求方式(*)
toolbar: '#toolbar', //工具按钮用哪个容器
striped: true, //是否显示行间隔色
cache: false, //是否使用缓存,默认为true,所以一般情况下需要设置一下这个属性(*)
pagination: true, //是否显示分页(*)
sortable: false, //是否启用排序
sortOrder: "asc", //排序方式
queryParams: oTableInit.queryParams,//传递参数(*)
sidePagination: "client", //分页方式:client客户端分页,server服务端分页(*)
pageNumber: 1, //初始化加载第一页,默认第一页
pageSize: 10, //每页的记录行数(*)
pageList: [10, 25, 50, 100], //可供选择的每页的行数(*)
clickToSelect:true,
showExport: true, //是否显示导出
exportDataType: "basic", //basic', 'all', 'selected'.
columns: [{
checkbox: true
}, {
field: 'Name',
title: '部门名称'
}, {
field: 'ParentName',
title: '上级部门'
}, {
field: 'Level',
title: '部门级别'
}, {
field: 'Desc',
title: '描述'
}, ]
}); 
Copy after login

还是来看重点:这两个属性

showExport: true, //是否显示导出
exportDataType: "basic", //basic', 'all', 'selected'.
showExport表示是否显示导出的按钮,exportDataType表示导出的模式是当前页、所有数据还是选中数据。
Copy after login

六、总结

以上就是功能的效果以及实现的简单代码。博主发现有几个问题有待解决。

1、行内编辑的功能是每一个单元格提交到后台,这样会造成数据库的频繁操作,感觉不太合适。不知道有没有更好的方式,每行提交到后台。

2、导出的功能虽然很好用,但是遗憾的是不支持IE浏览器,博主试过官网上面的example,好像IE也导出不了。待验证。
