做网站代理商好赚吗?彩票网站建设古大学

这里推荐一个前端框架 sakuya / SCUI，他里面有个formTable，可以解决很多订单明细保存得问题。基本沿用element-plus的前端使用模式，让表单表格变的非常容易。

这个的供应商插件，当使用filterable后，点击表格重的选项，下拉的表格不会关闭。去掉filterable就可以了

<sc-table-select :table-width="450" :apiObj="apiObj" @change="change" :props="props" :params="params"clearable filterable><el-table-column prop="code" label="编码"></el-table-column><el-table-column prop="name" label="名称"></el-table-column><el-table-column prop="contacts" label="联系人"></el-table-column><el-table-column prop="phone" label="手机号"></el-table-column><el-table-column prop="address" label="地址"></el-table-column><el-table-column prop="creditCode" label="统一社会信用代码"></el-table-column></sc-table-select>

网上有不少同类型的问题element ui el-select点击图标无法关闭下拉框问题
el-select 中加了filterable 点击箭头下拉框回收不去问题
那么如何解决当前的问题呢？选中数据后，这个被执行了两次

是不是visible-change没搞懂是怎么回事，于是按照这个思路去调查，el-select内嵌套el-select—筛选下拉列表遇到的若干问题及解决
el-select二次封装，解决数据量太大导致卡顿问题，实现远程搜索，滚动加载数据，搜索数据回显
visible-change对应的参数官方只有一个，这个跟网上有些资料不一致，可能是版本不同。

因此推断，当select展开的时候就会触发visible-change这个事件，那么什么时候可以触发展开呢？不会不会只要有值输入进去，就会触发呢？
element-UI之el-select的坑，这个有类似的问题，但是却没有解决方案。
在别人的基础上增加了hasClick，点击了做一个标记，然后再清理的时候恢复。
