Angular Material 2:修复多行错误消息 [英] Angular Material 2: Fix for Multiline Error messages

问题描述

我在我的角度应用程序中使用了角度材料 2.当我的表单输入字段错误消息不止一行时，我遇到了问题.这是照片:

I'm using angular material 2 inside my angular application. I'm experiencing a problem when my form input field error messages are more than one line. Here is the photo:

代码如下:

<md-error *ngIf="password.touched && password.invalid">
          <span *ngIf="password.errors.required">
                {{'PASSWORD_RECOVERY.FIELD_REQUIRED' | translate}}
          </span>
          <span *ngIf="password.errors.minlength || password.errors.maxlength">
                {{'PASSWORD_RECOVERY.PASSWORD_LENGTH' | translate}}
          </span>
          <span *ngIf="password.errors.pattern">
                {{'PASSWORD_RECOVERY.FOR_A_SECURE_PASSWORD' | translate}}
          </span>
</md-error>

我通过阅读 github 了解到，这是 angular 2 材料中的一个错误.有人通过自定义解决方法解决了这个问题吗?

I've understood by reading github, that it is a bug in angular 2 material. Did anybody manage to solve this issue by doing a custom workaround?

推荐答案

问题是类.mat-form-field-subscript-wrapper的元素是position: absolute，所以它不占用实际空间.

The problem is that the element with class .mat-form-field-subscript-wrapper is position: absolute, so it's not occupying real space.

正如 关于 github 上的这个问题 的建议，xumepadismal，您可以添加此 scss 作为解决我问题的解决方法:

As suggested on this issue on github by xumepadismal, you can add this scss as workaround that solved my problem:

// Workaround for https://github.com/angular/material2/issues/4580.
mat-form-field .mat-form-field {
  &-underline {
    position: relative;
    bottom: auto;
  }
  &-subscript-wrapper {
    position: static;
  }
}

它在静态 div 中转换 .mat-form-field-subscript-wrapper 节点，并在 .mat-form-field-unterline 之后重新定位输入框.

It transforms the .mat-form-field-subscript-wrapper node in a static div, and repositionate the .mat-form-field-unterline just after the input field.
