Easyui 实现3级联动的用户选择功能
3级联动用户选择功能
由于最近开发了一个新的办公信息系统,需要用到站内信功能,发站内信时接受人的信息是用点选的,找了好多资料,但实现起来还是比较麻烦,做完上去easyui的官网看了下,已经更新到1.4.2了,看了下更新内容新增了datalist的功能,昨晚睡前想好实现的思路,今天一早开始码代码!很简单的一个方法,放上来分享,没有demo,只说说实现的方法和简单的代码。
先上一张图吧!
左边的部门是个tree,点击部门的时候,会获取该部门的用户,获取到的用户显示到中间的“待选用户”里,单击"待选用户"的姓名,会直接在已选用户中插入。
单击部门的tree组件的时候,会获取“已选用户”的uid,然后将获取到的uid和部门id发给后台过滤,这样,“待选用户”里的数据就不会和“已选用户”的数据重复。
先看看selectUser.html的代码吧!<div>

不太懂去表达要去表达的东西,希望可以看得懂,也希望可以帮到您,更希望大家可以给更好的建议!!勿喷~~~~
pm:easyui是最新的1.4.2版本,老版本没有datalist组件的!!

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
