VUE加elementUI的一个坑.随便记录一下
首先前端用uniapp写是效果不错的.
后端管理页面用vue+elementUI(饿了么UI),配合起来就可以做一个相当完整的项目了.
但是我最近发现一个坑.我估计只有做过的才知道.
比如一个按钮绑定了事件:
@onclick(hanshu(canshu))
如果hanshu里面的参数是变量传进来的
data:{
canshu:[],
table:[]
}
hanshu(val){
table = val (如果这样赋值)
}
页面显示:
div里面放input ,input的内容用for 循环循环出table数组里面的内容.
然后你修改input的内容会发现,canshu的内容也会改变....这就是双向绑定.
也就是说,一个变量a,你传参传给别的变量A,别的地方改了,而且改的是别的变量A,那么变量a也会跟着改变...
想来想去没办法,最后发现一个解决办法:
就是把变量a里面每一个成员单独的赋值给变量A,然后这种情况就解决了.....
碰巧发现的一个问题....
