我是新的角4,并试图找到一个库为平底锅缩放。我在国家预防机制上找不到任何包裹。我试图在我的项目中添加jquery,然后添加了jquery.panzoom,但是由于jquery.panzoom是用JavaScript编写的,而我的angular项目是用TypeScript编写的,所以jquery.panzoom没有@types,所以它不能工作。
我遵循的步骤
1) npm安装--保存jquery
2) npm安装-保存@type/jquery
3)从‘jquery’导入*作为$;
//till here jquery works fine
$('.sample').click(function () {
alert('div clicked.');
});3) npm安装--保存jquery.panzoom
$('#panzoomDiv').panzoom(
{
$zoomIn: $('.zoom-in'),
$zoomOut: $('.zoom-out'),
$zoomRange: $('.zoom-range'),
$reset: $('.reset')
}
);在这里我得到了错误
src/app/app.component.ts (22,22): Property 'panzoom' does not exist on type
'JQuery<HTMLElement>'.然后,在通过这之后,我添加了
interface JQuery {
panzoom(options: any): any;
}到我的typings.d.ts文件。现在它确实编译了,但是给出了这个运行时错误。
ERROR TypeError: __WEBPACK_IMPORTED_MODULE_1_jquery__(...).panzoom is not a function

尝试过这种方法,还是不起作用。
<div style="display:block; padding: 10px;">
<button id="btn-zoom-in-workspace"
class="zoom-out">Zoom Out
</button>
<button id="btn-zoom-null-workspace"
class="reset">Reset
</button>
<button id="btn-zoom-out-workspace"
class="zoom-in">Zoom In
</button>
<input type="number" class="zoom-range">
</div>
<div id="panzoomDiv" #panzoomDiv>
<div>
import * as $ from 'jquery';
@Component({
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.css']
})
export class AppComponent implements AfterViewInit {
@ViewChild('panzoomDiv') panzoomDiv: ElementRef;
ngAfterViewInit(): void {
if (this.panzoomDiv)
$(this.panzoomDiv.nativeElement).panzoom({
$zoomIn: $('.zoom-in'),
$zoomOut: $('.zoom-out'),
$zoomRange: $('.zoom-range'),
$reset: $('.reset')
});
}

将这些添加到角-cli.json的脚本数组中。
"scripts": [
"../node_modules/jquery/dist/jquery.min.js",
"../node_modules/jquery.panzoom/dist/jquery.panzoom.min.js"
],在模板中
<div style="display:block; padding: 10px;">
<button id="btn-zoom-in-workspace"
class="zoom-out" #reference>Zoom Out
</button>
<button id="btn-zoom-null-workspace"
class="reset" #reference>Reset
</button>
<button id="btn-zoom-out-workspace"
class="zoom-in" #reference>Zoom In
</button>
<input type="number" class="zoom-range">
</div>
<div id="panzoomDiv" #panzoomDiv>
<div>在组件中,使用以下内容
declare var $ : any;
@ViewChild('panzoomDiv') panzoomDiv: ElementRef;
//get all the other element references using elementref and use it in function below
ngAfterViewInit(): void {
if (this.panzoomDiv)
$(this.panzoomDiv.nativeElement).panzoom({
$zoomIn: $(#reference),
$zoomOut: $(#reference),
$zoomRange: $(#reference),
$reset: $(#reference)
});
