给Jquery easyui 的datagrid 每行增加操作链接

通过formatter方法给Jquery easyui 的datagrid 每行增加操作链接
我们都知道Jquery的EasyUI的datagrid可以添加并且自定义Toolbar,这样我们选择一行然后选择toolbar的相应按钮就可以对这行的数据进行操作。但实际项目里我们可能需要在每行后面加一些操作链接,最常见的就是比如“修改”、“删除”、“查看”之类。如下图:
给Jquery easyui 的datagrid 每行增加操作链接

这是个很实用的功能,但是搜索了一下,好像也没见到谁写过,我就找了Easyui的document,随便写一下,抛砖引玉。

思路:一般来讲,增加操作链接就是要用URL+ID的方式把页面跳转到新页面,所以需要在正常输出的一行后面加一列操作列用来显示操作链接。Easyui的Datagrid没有直接添加link的属性,所以我需要格式化一下这一“操作”列的输出。

解决方法:

第一步,我需要 在datagrid行里添加一列,field指向id(field:'id'),然后对这列进行格式化处理(formater:格式化函数),如下: <th>操作</th>

第二步:
根据documentation的描述,formatter的格式化函数有3个parameters,分别是:
value: the field value,也就是field:'id'。
rowData: the row record data。就是这一行的Json数据,包括你已经选择在Datagrid上显示的内容,和没显示的内容。因为我的Json数据里包括了Id这一内容,所以我可以直接调用。如果你作为数据源的Json里没有Id属性,需要修改一下Json的输出。我的每行Json输出是类似{"id":"1","name":"\u7ecf\u6d4e\u53d1\u5c55","parentId":"0"}的结构
rowIndex: the row index.当前行的Index。

所以我写rowformater这个函数的时候,也需要用function rowformater(value,row,index)的方法。为了看起来清晰明白,我只在函数里写了一句话(放在

标签里),事实上项目上需要做一些基本的判断。: <script><br /> function rowformater(value,row,index)<br /> {<br /> return "<a href='"+row.id+"' target='_blank'>操作";<br /> }<br /> </script>OK,应该能跑起来了。跑出的结果就是上面的截图样式。

Guidance and Examples: Learn to implement the selection sort algorithm in Java Guidance and Examples: Learn to implement the selection sort algorithm in Java Feb 18, 2024 am 10:52 AM

Java Selection Sorting Method Code Writing Guide and Examples Selection sorting is a simple and intuitive sorting algorithm. The idea is to select the smallest (or largest) element from the unsorted elements each time and exchange it until all elements are sorted. This article will provide a code writing guide for selection sorting, and attach specific Java sample code. Algorithm Principle The basic principle of selection sort is to divide the array to be sorted into two parts, sorted and unsorted. Each time, the smallest (or largest) element is selected from the unsorted part and placed at the end of the sorted part. Repeat the above
