nz-select 数据源在数据量过大时可设置加载数据量的条数

[HelloValue]

What problem does this feature solve?

数据量过大时需要配合搜索的情况。目前数据量过大会导致初始化组件时，页面无反应。搜索也比较迟钝。

What does the proposed API look like?

<nz-select
nzShowSearch
nzAllowClear
nzPlaceHolder="选择..."
[(ngModel)]="selected"
[nzDataSource]="data"
>
<ng-container *ngFor="let b of data">
<nz-option [nzValue]="b.Id" [nzLabel]="b.Name">

Translation of this issue:

nz-select Data source can set the number of loaded data when the amount of data is too large

What problem does this feature solve?

When the amount of data is too large, it is necessary to match the search. When the current data volume is over the assembly, the page does not respond when the component is initialized. Search is also slow.

What does the proposed API look like?

<nz-select
          nzShowSearch
          nzAllowClear
          nzPlaceHolder="Select..."
          [(ngModel)]="selected"
          [nzDataSource]="data"
          >
          <ng-container *ngFor="let b of data">
            <nz-option [nzValue]="b.Id" [nzLabel]="b.Name">

可设置加载数据量的条数 可以自己限制，数组一个slice操作

<nz-option *ngFor="let b of brCollectionList.slice(0,300)" [nzValue]="b.brandCollectionId" [nzLabel]="b.brandCollectionName">
这样的话，搜索也搜索不到 300条以后的数据了。

搜索和数据展示本来就是一体的，数据量过大时不建议使用前端搜索

不考虑增加一个选项单独把搜索数据源和展示数据源分开么？

你可以很方便的通过 nzOnSearch 自行修改数据源数据
