bootstrap模态框——使用一个模态框完成两个功能

来源:Eve慕 发布时间:2018-07-02 15:23:31 阅读量:1287

在用户列表中希望能用同一个模态框完成添加用户和修改用户两个功能。

添加界面
添加用户 
修改用户
修改用户

这两个功能在提交表单之后都会返回原页面,所以使用ajax进行处理 
主要的难点在于: 
1、在点击不同按钮时调用不同函数。 
在点击修改页面时,需要将当前用户的信息传入模态框中,并设置用户名字段为不可修改,点击模态框中提交时调用后台修改的方法;在点击添加页面时,需要清空之前模态框中数据,点击提交按钮时,调用的是后台中添加的方法。 
2、不同功能的表单验证不同。 
表单验证使用jQuery validate插件。在添加时,需要验证用户名不为空、长度和是否重复。而修改时不需要对用户名做验证。所以需要自定义validate。 
3、关于用户id的赋值。 
修改功能中,需要将当前表单内容和用户id一起传入后台,才能进行修改。而添加时,由于在数据库中将用户id设为自增模式,所以不需要传id的值,只传其他字段的值即可。但是表单数据的传输是封装好之后一起传输,所以要做额外处理。
