复制提示

效果图如下：

首先简单说明一下，后面会给所涉及到的代码都贴上来的。

1.excel图标是一个用户控件，用来触发下载

2.首页、上页......每页多少条，这一块是一个整体，你可以选择放置在表格下面，或者表格上面都可以

3.表格则也是单独的一个，自己任意设置位置

4.复选框是否显示，自己设置，并可设置绑定的值，并有自带的方法可供你用于获取选中的复选框的对象跟值

5.表格的单行、双行、点击、悬浮、标题栏、表格的样式，都可以通过设置参数来修改，图为自带的效果

6.分页默认每页10行，分页的检测、复选框选择的检测，都已封装好

7.每页显示的数量、以及跳转到第几页的事件也都已经写好

8.关于导出按钮的数据导出功能，数据查询的时候，将数据绑定到用户控件中，而导出按钮则用来检测是否有复选框，如果有复选框，则用来先检测用户选中的进行拼接导出

功能大概就上面这些了吧，先给调用的方法贴上来。

} function TableDataEvent(nowPage) {
var sql = "select * from camera_fault t";

CommonJS.HtmlTableOperation.SetCheckbox(true, "CF_CAMERAID"); // 设置是否显示复选框，以及复选框绑定那个列，传数据库的列名进去 // 绑定行事件
// CommonJS.HtmlTableOperation.trClickFun = trC;
// CommonJS.HtmlTableOperation.trDblclickFun = trC;
// CommonJS.HtmlTableOperation.trMouseFun = trC;
// CommonJS.HtmlTableOperation.trOutFun = trC; CommonJS.HtmlTableOperation.LoadData("div_TableData", dt); // 加载数据。传递 divID 以及 DataTable
} // 获取用户选中的复选框的value值
function GetCheckedValue() {
CommonJS.HtmlTableOperation.GetCheckedValue("div_TableData");
}
// 行的方法，返回行对象
function trC(obj) {
alert(obj.innerHTML);
}
</script>
</head>
<body onload="PageInfoEvent();TableDataEvent(1);">

<div id="div_TableData">

</form>
</body>
</html>

简单说说代码的调用：
1.自己定义好两个div，一个用户控件。两个div呢，一个是放置上一页下一页的位置，另外一个div则用来放置table的位置，至于用户控件，放上来之后，可以隐藏，也可以显示，这个随意。

2.PageInfoEvent的三行代码，只需要理解第三行代码就够了，第二行的代码通过ajax从后台获取一个总数。而第三行代码则是调用封装的封装代码，你需要传入三个参数，一个参数是分页按钮显示的div的ID，之后就是总数，最后一个是回调函数，该回调函数是用来当分页触发之后调用的方法，封装的方法会返回一个页数回来。

3.TableDataEvent事件中，获取页数。从后台查询该页的数据

之后里面有各种参数设置，比如：显示的列名、每个列对应绑定的数据列、是否显示复选框、复选框绑定哪个列、设置每页显示的数量、行的单击双击悬浮离开事件的绑定、表格的颜色，皆可自定义设置，当然，你若不设置，也都可以，都有默认值。

4.此处需要注意的是：数据类型暂时限制了C#中的DataTable类型，因为现有的项目全是这个类型的，所以先用这个数据类型来写这个例子，如果要用其它类型，自己改代码

5.后面还有两个方法，一个是GetCheckedValue，是获取用户选中的值。TrC呢，是在加载table数据的时候，你绑定了回调方法，那么就在回调的时候，将当前行的对象返回给你自定义
