带有浏览器前缀的Angular 2 ngStyle

Question

这不起作用：

<div [style.-moz-column-count]="columns"></div>
<div [ngStyle]="{'-moz-column-count': columns}"></div>
<div style="-moz-column-count: {{columns}}"></div>

有没有办法避免Sanitizer？ 我找到了一个绕过该值的Pipe，但没有找到属性名称。

import {DomSanitizationService} from '@angular/platform-browser';
@Pipe({name: 'safe'})
export class SafePipe {
    constructor(sanitizer:DomSanitizationService){
        this.sanitizer = sanitizer;
    }

    transform(style) {
        return this.sanitizer.bypassSecurityTrustStyle(style);
    }
}

有什么想法使用这个属性？

Answer 1

你需要这样写：

this.style = {
  "MozColumnCount": 3,
  "column-count": 3,
}

<div [ngStyle]="style">

Answer 2

我认为使用angular2 ngStyle是不可能的。

您可以使用ngClass选项和scss这样：

@for $i from 1 through 6 {
    .columns-#{$i} {
        -webkit-column-count: #{$i};
        -moz-column-count: #{$i};
        column-count: #{$i};
    }
}
