问题描述

我正在尝试使我的材质对话框在右上角有一个X按钮，但是我在定位上遇到了问题.

I am trying to get my material dialog to have an X button at the top right, but I am having problems with the positioning.

component.ts

this.d.open(loginComponent, {
  width: '300px',
  height: '',
  panelClass: 'dialogC',
});

component.html

<mat-dialog-content>
    <button mat-button class="close-icon" [mat-dialog-close]="true">
        <mat-icon>close</mat-icon>
    </button>
    <h2 mat-dialog-title>Login</h2>

style.scss

.dialogC {
  position: relative !important;
}

.close-icon {
  position: absolute;
  top: 0;
  right: 0;
  transform: translate(50%, -50%);
}

X只是左对齐，而不是右对齐.有建议吗?

The X is just aligned to the left instead of top right. Suggestions?

更新，这是添加flex之后出现的问题:

推荐答案

<button class="close" mat-button (click)="onNoClick()">X</button>
<h1 mat-dialog-title>Login</h1>
<div mat-dialog-content>
...
...
</div>

CSS:(请以全局( styles.css )形式提供，或提供ViewEncapsulation.NONE，否则这些样式将不受影响.)

CSS: (Please give it in global (styles.css) or give ViewEncapsulation.NONE or else these styles wont affect.)

.cdk-overlay-pane.my-dialog {
  position: relative!important;
}
.close.mat-button {
  position: absolute;
  top: 0;
  right: 0;
  padding: 5px;
  line-height: 14px;
  min-width: auto;
}

请注意，在CSS中，我们现在有了一个新的类 .my-dialog

Note that in the CSS We now have a new class out of thin air .my-dialog

因此，请在dialogRef中像下面的panelClass所述，

So, please mention that as panelClass in dialogRef like below,

this.dialog.open(DialogComponent, {
      width: '250px',
      panelClass: 'my-dialog',
..
..

这会给我带来以下结果，

This yields me the following result,
