PHP+ajax+layui实现双重列表的动态绑定

牧童牵黄牛2023-12-06 16:31

需求：商户下面有若干个门店，每个门店都需要绑定上收款账户

方案一：每个门店下面添加页面，可以选择账户去绑定。（难度：简单）

方案二：从商户进入，可以自由选择门店，以及账户，动态绑定（难度：较复杂）

页面：

实现方式，通过选择上面的门店，打勾之后，在选择账户里面的账户，即可实现下面的列表的动态返回，然后点击保存之后，即可将门店和账户的绑定规则传到后台，由后台统一处理

这里页面显示的字符串本来是可以由后台返回，然后js动态拼接的，但是，考虑到js写逻辑过于复杂，操作性不如PHP简易，所以由后台PHP，拼接字符串，然后返回的拼接html代码，直接显示

关联表的数据表结构

可能有其他的办法，我这个也或许不是最优解，因为本该前端处理的dom数据，由PHP处理返回了

另外，如果是前端直接写在页面上的HTML代码，一些，onclick等事件，可以直接绑定，进行监听操作，但是如果是由拼接上的字符串，动态显示的，类似于，富文本内容，则需要加上限定

需要把代码都放在$(document)的后面才能执行，不能直接写js代码

html 复制代码 
 $(document).on('click', '.delete_adapay', function() {
    //内容
}
