我的html以下:
<li>
<div class="w3l_banner_nav_right_banner1" style="background:url('./assets/images/2.jpg') no-repeat 0px 0px;">
<h3>Make your <span>food</span> with Spicy.</h3>
<div class="more">
<a href="products.html" class="button--saqui button--round-l button--text-thick" data-text="Shop now">Shop now</a>
</div>
</div>
</li>
问题:
我想用/assets/images/2.jpg
等动态变量替换图片网址{{ article.uri }}
。
我尝试了以下几种方法参考:
Attribute property binding for background-image url in Angular 2
How to add background-image using ngStyle (angular2)?
到目前为止已经尝试过:
<li *ngFor="let article of arr;let i=index;">
<div *ngIf="i == 0" class="w3l_banner_nav_right_banner" [ngStyle]="{ 'background-url': 'url('+article.uri+')'} no-repeat 0px 0px;">
<h3>Make your <span>food</span> with Spicy.</h3>
<div class="more">
<a href="products.html" class="button--saqui button--round-l button--text-thick" data-text="Shop now">Shop now1</a>
</div>
</div>
</li>
我正在使用Angular 4.1.3。

background-url
是不正确的CSS,请改用background
或background-image
。
以下是正确语法的示例:
<div [ngStyle]="{'background': '#fff url(' + article.uri + ') no-repeat 0 0'}"></div>
您的完整示例如下所示:
<li *ngFor="let article of arr; let i=index;" >
<div *ngIf="i == 0"
class="w3l_banner_nav_right_banner"
[ngStyle]="{'background': '#fff url(' + article.uri + ') no-repeat 0 0'}" >
<h3> Make your <span>food</span> with Spicy. </h3>
<div class="more">
<a href="products.html" class="button--saqui button--round-l button--text-thick" data-text="Shop now">Shop now1</a>
</div>
</div>
</li>

如果您从远程来源或用户输入获取背景图片,则需要angular sanitize the url。在您的组件中,您将需要添加以下代码...
import { DomSanitizer } from '@angular/platform-browser';
export class YourComponent {
constructor(private _sanitizer: DomSanitizer) { }
public sanitizeImage(image: string) {
return this._sanitizer.bypassSecurityTrustStyle(`url(${image})`);
}
}
尝试将HTML设置为此...
<li *ngFor="let article of arr;let i=index;">
<div *ngIf="i == 0" class="w3l_banner_nav_right_banner" [style.background-image]="sanitizeImage(article.uri)">
<h3>Make your <span>food</span> with Spicy.</h3>
<div class="more">
<a href="products.html" class="button--saqui button--round-l button--text-thick" data-text="Shop now">Shop now1</a>
</div>
</div>
</li>
并在您附加到div的某些课程中应用no-repeat 0px 0px;
。

正确答案是[style.background-image]="'url(' + article.uri + ')'"
但是如果您将 ngFor 用于轮播,请确保您已正确添加类“活动” 。
此代码将不有效:
<div class="carousel-item active"
*ngFor="let article of arr;"
[style.background-image]="'url(' + article.uri + ')'"></div>
您应该仅将'active'类用于第一项!
<div class="carousel-item"
*ngFor="let article of arr; let i = index;"
[ngClass]="{'active': i === 0}"
[style.background-image]="'url(' + article.uri + ')'"></div>

您可以通过在单个变量中添加url路径来使用它。 例如
bgImageVariable="www.domain.com/path/img.jpg";
[ngStyle]="{'background-image': 'url(' + bgImageVariable + ')'}"

为Angular 8工作: 在组件中,定义ngStyle对象var(此处称为样式,在构造函数中初始化):
let bgImageUrl = 'assets/images/dot-grid.png'
let styles = {
backgroundImage: `url(${bgImageUrl})`
};
在模板中,将其分配为ngStyle
<div [ngStyle]="styles"><!-- your content --></div>

这对我来说很好用:
js文件:
path = 'url(../assets/about.png)';
<强>数组:强>
string[] = [this.path];
和HTML文件:
<div *ngFor="let item of array" [ngStyle]="{'background-image': item}">
