angular - 绑定表达式不能在表达式 ANGULAR 7 的末尾包含链式表达式

问题描述

npm run build 时显示的错误

    Parser Error: Binding expression cannot contain chained expression at the end of the expression [getImageUrl(image, true);] in E:/Work/JamesJ/Pixie/pixie-image-editor/source/src/app/image-editor-ui/panels/open-sample-image-panel/open-sample-image-panel.component.html@34:9 ("

: Parser Error: Binding expression cannot contain chained expression at the end of the expression [getImageUrl(image, true);] in E:/Work/JamesJ/Pixie/pixie-image-editor/source/src/app/image-editor-ui/panels/open-sample-image-panel/open-sample-image-panel.component.html@34:9 ("ngIf="sampleImages" >
    <img [src]="getImageUrl(image, true);" *ngFor="let image of sampleImages" [ERROR ->](click)="openSampleImage(image)">
</div>")

html代码是

    <div class="samples" *ngIf="sampleImages" >
    <img [src]="getImageUrl(image, true);" *ngFor="let image of sampleImages" (click)="openSampleImage(image)">
</div>

组件代码是： 

public getImageUrl(image: SampleImage, useThumbnail = false) : string {
    const url = (image.thumbnail && useThumbnail) ? image.thumbnail : image.url;
    // prefix relative link with base url, if needed
    if (url.indexOf('//') === -1) {
        return this.config.getAssetUrl(url);
    } else {
        return url;
    }
}

解决方案

删除分号：

    <img [src]="getImageUrl(image, true)" ...>
