    按钮尺寸

    按钮有大、中、小三种尺寸。

    通过设置 nzSize 为 largesmall 分别把按钮设为大、小尺寸。若不设置 nzSize，则尺寸为中。

    1. import { Component } from '@angular/core';
    3. @Component({
    4.   selector: 'nz-demo-button-size',
    5.   template: `
    6.     <nz-radio-group [(ngModel)]="size">

    40.     `
    41.   ]
    42. })
    43. export class NzDemoButtonSizeComponent {
    44. }

    添加 nzLoading 属性即可让按钮处于加载状态，最后两个按钮演示点击后进入加载状态。

    按钮组合

    可以将多个 nz-button 放入 nz-button-group 的容器中。

    通过设置 nzSize 为 largesmall 分别把按钮组合设为大、小尺寸。若不设置 nzSize，则尺寸为中。

    1. import { Component } from '@angular/core';

    nzBlock 属性将使按钮适合其父宽度。

    1. import { Component } from '@angular/core';
    3. @Component({
    4.   selector: 'nz-demo-button-block',
    5.   template: `

    19. export class NzDemoButtonBlockComponent {}

    图标按钮

    当需要在 nz-button 内嵌入图标时，可以直接在 nz-button 内嵌入对应的 icon。

    添加 disabled 属性即可让按钮处于不可用状态，同时按钮样式也会改变。

    1. import { Component } from '@angular/core';
    3. @Component({
    4.   selector: 'nz-demo-button-disabled',
    5.   template: `
    6.     <button nz-button nzType="primary">Primary</button>

    30. })
    31. export class NzDemoButtonDisabledComponent {}

    多个按钮组合

    按钮组合使用时，推荐使用1个主操作 + n 个次操作，3个以上操作时把更多操作放到 nz-dropdown 中组合使用。

    1. import { Component } from '@angular/core';
    3. @Component({
    4.   selector: 'nz-demo-button-multiple',
    5.   template: `
    6.     <button nz-button nzType="primary">primary</button>
    7.     <button nz-button nzType="default">secondary</button>
    8.     <button nz-button nz-dropdown [nzDropdownMenu]="menu">Actions<i nz-icon nzType="down"></i></button>
    9.     <nz-dropdown-menu #menu="nzDropdownMenu">
    10.       <ul nz-menu>
    11.         <li nz-menu-item>
    12.           <a>1st item</a>
    13.         </li>
    14.         <li nz-menu-item>
    15.           <a>2nd item</a>
    16.         </li>
    17.         <li nz-menu-item>
    18.           <a>3rd item</a>
    19.         </li>
    20.       </ul>
    21.     </nz-dropdown-menu>
    22.   `,
    23.   styles: [
    24.     `
    25.       [nz-button] {
    26.         margin-right: 8px;
    27.         margin-bottom: 12px;
    28.       }
    29.     `
    30.   ]
    31. })

    添加 nzGhost 属性后，幽灵按钮将其他按钮的内容反色，背景变为透明，常用在有色背景上。

    通过设置 Button 的属性来产生不同的按钮样式，推荐顺序为：nzType -> nzShape -> nzSize -> nzLoading -> disabled
