Angular 2和砖石网格第三方库 [英] Angular 2 and masonry grid third party library

问题描述

我想在Angular 2应用程序中使用Masonry Grid.

我安装了一个: http://masonry.desandro.com/

与:npm install masonry-layout --save

，并且我通过angular-cli.json

 "scripts": [
        "../node_modules/masonry-layout/dist/masonry.pkgd.min.js"
      ],

，它也起作用.

在应用程序中，如果我在Web浏览器中打开控制台并键入以下代码:

var elem = document.querySelector('#masonry-grid');
var msnry = new Masonry( elem, {
  // options
  itemSelector: '.grid-item',
  columnWidth: 200
});

一切正常.

现在，我想实现该功能以使其自动运行.那我做了什么?

在组件中，我正在使用

ViewChild(@ViewChild('masonryGrid') masonryGrid: ElementRef;)

获取div并替换了这行纯javascript行

var elem = document.querySelector('#masonry-grid');

现在，我正在努力为Masonry创建types.d.ts，而这一部分对我来说还不是很清楚.

我试图在组件顶部以这种方式声明变量.

declare var Masonry: any;

然后在ngAfterViewInit()中执行此操作

new Masonry(this.masonryGrid.nativeElement, {
  // options
  itemSelector: '.grid-item',
  columnWidth: 200
});

所有内容也都进行了编译，我在控制台中看不到任何错误，但是Masonry没有实例化，因此无法正常工作.

任何帮助将不胜感激.

它开始起作用.看来angular-cli webpack出现了问题.有时它无法自动识别更改.它在控制台中说什么都没有改变".我重新启动服务器，它开始工作.

解决方案

Angular 2有一个移植的Masonry模块.

可以在 此处找到.

您需要将其导入到主模块或共享模块中.

import { MasonryModule } from 'angular2-masonry';

@NgModule({
  imports: [
    MasonryModule
  ]
})

示例组件如下:

 @Component({
   selector: 'my-component',
   template: `
     <masonry>
        <masonry-brick class="brick" *ngFor="let brick of bricks">
        {{brick.title}}</masonry-brick>
     </masonry> `
 })
 class MyComponent {
   bricks = [
     {title: 'Brick 1'},
     {title: 'Brick 2'},
     {title: 'Brick 3'},
     {title: 'Brick 4'},
     {title: 'Brick 5'},
     {title: 'Brick 6'}
  ]
 } 

I want to use Masonry Grid in Angular 2 application.

I installed this one: http://masonry.desandro.com/

with: npm install masonry-layout --save

and I include that via angular-cli.json

 "scripts": [
        "../node_modules/masonry-layout/dist/masonry.pkgd.min.js"
      ],

and that works as well.

In application if I open console in web browser and type this piece of code:

var elem = document.querySelector('#masonry-grid');
var msnry = new Masonry( elem, {
  // options
  itemSelector: '.grid-item',
  columnWidth: 200
});

Everything works as well.

Now I want to achieve that to work automatically. So what I did?

In component I'm using

ViewChild ( @ViewChild('masonryGrid') masonryGrid: ElementRef; )

to get the div and that replaces this line of pure javascript line

var elem = document.querySelector('#masonry-grid');

Now I'm struggling with creating typings.d.ts for Masonry and that part isn't yet totally clear for me.

I tried at the top of component to declare variable on this way.

declare var Masonry: any;

and then in ngAfterViewInit() to do this

new Masonry(this.masonryGrid.nativeElement, {
  // options
  itemSelector: '.grid-item',
  columnWidth: 200
});

Everything was compiled as well and I don't see any errors in console, but Masonry is not instantiated and it doesn't work.

Any kind of help will be appreciated.

EDIT:

It started to work. It seems how there was problem with angular-cli webpack. Sometimes it doesn't recognize changes automatically. It said "Nothing changed" in console. I restarted server and it started to work.

解决方案

There is a ported Masonry module for Angular 2.

It can be found here.

You need to import it into your main module, or a shared module.

import { MasonryModule } from 'angular2-masonry';

@NgModule({
  imports: [
    MasonryModule
  ]
})

A sample component looks like this:

 @Component({
   selector: 'my-component',
   template: `
     <masonry>
        <masonry-brick class="brick" *ngFor="let brick of bricks">
        {{brick.title}}</masonry-brick>
     </masonry> `
 })
 class MyComponent {
   bricks = [
     {title: 'Brick 1'},
     {title: 'Brick 2'},
     {title: 'Brick 3'},
     {title: 'Brick 4'},
     {title: 'Brick 5'},
     {title: 'Brick 6'}
  ]
 }
