数字和文本列的垫子排序问题 [英] Mat Sort Issue for Numbers and Text Columns

问题描述

我有角材料数据源.角材料版本是 ^5.0.3 排序工作.但是，对于某些列，它的排序不正确.数字和文本在哪里.例如，排序结果如XXX"、1"、1tesxt"、1"、OPD"、OXD"、12".

感谢您的帮助.

解决方案

这是因为标准的 sortingDataAccessor 将数字字符串转换为数字并且在 Javascript 中 1 >'一个' 和 1 <'one' 都计算为 false.

作为一种解决方法，您可以定义自己的 sortingDataAccessor 而无需强制转换:

ngAfterViewInit() {this.dataSource.sort = this.sort;this.dataSource.sortingDataAccessor =(数据，属性)=>数据[属性];}

I have angular material datasource. angular material version is ^5.0.3 Sorting is working. However for some columns it is sorting incorrectly. where number and text is there. For instance, sorted result like, 'XXX', '1', '1tesxt', '1', 'OPD', OXD', '12'.

<mat-table #table [dataSource]="dataSource" matSort > 
  <ng-container matColumnDef="model">
    <mat-header-cell *matHeaderCellDef mat-sort-header> Model </mat-header-cell>
    <mat-cell *matCellDef="let element"> {{element.model}} </mat-cell>
  </ng-container>

Appreciate your help.

解决方案

This is because the standard sortingDataAccessor casts number strings to number and in Javascript 1 > 'one' and 1 < 'one' both evaluates to false.

As a workaround, you can define your own sortingDataAccessor without the cast:

ngAfterViewInit() {    
  this.dataSource.sort = this.sort;
  this.dataSource.sortingDataAccessor = (data, attribute) => data[attribute];
}

The workaround is copied from this Github issue.
