我之前看到Angular2推出了RC5,所以我决定更新我的一个测试应用程序以查看更改以及如何调整。这个应用程序正在使用Material2,我也将其更新为Alpha 7.2,但是在尝试使用md-button组件时出现此错误
“模板解析错误:无法绑定到'md-ripple-trigger',因为它 不是'div'的已知属性。 ( “* ngIf =” isRippleEnabled()” 类= “MD-按钮纹波” [class.md-button-ripple-round] =“isRoundButton()”[错误 - >] [md-ripple-trigger] =“getHostElement()”[md-ripple-color] =“isRoundButton()?'rgba(255,255,255,0.2)”): MdButton @ 0:180无法绑定到'md-ripple-color',因为它不是已知的 'div'的财产。 (“吨纹波” [class.md按钮纹波轮] = “isRoundButton()” [md-ripple-trigger] =“getHostElement()”[错误 - >] [md-ripple-color] =“isRoundButton()?'rgba(255,255,255,0.2)':''”md-ripple-background-color =“rgb”):MdButton @ 0: 219"
我正在尝试添加一个名为nav-bar
的新组件上使用它,这里是添加了材料的Angular CLI创建的文件
TypeScript文件
import { Component, OnInit } from '@angular/core';
import { MdToolbar } from '@angular2-material/toolbar';
import { MdButton } from '@angular2-material/button';
import { MdIcon, MdIconRegistry } from '@angular2-material/icon';
@Component({
moduleId: module.id,
selector: 'nav-bar',
templateUrl: 'nav-bar.component.html',
styleUrls: ['nav-bar.component.css'],
directives: [
MdToolbar,
MdButton,
MdIcon
],
providers: [
MdIconRegistry
]
})
export class NavBarComponent implements OnInit {
constructor() {}
ngOnInit() {
}
}
HTML文件
<md-toolbar>
<button md-button>
<md-icon>menu</md-icon>
</button>
NavBar
</md-toolbar>
答案 0 :(得分:9)
尝试在MdRippleModule
中导入AppModule
:
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import { HttpModule} from '@angular/http';
import { MdRippleModule } from '@angular2-material/core/core'; <== this line
@NgModule({
imports: [ BrowserModule, HttpModule, MdRippleModule ], <== add here
declarations: [ AppComponent ],
bootstrap: [ AppComponent ]
})
export class AppModule { }
或者在组件中传递MdRipple
指令:
...
import { MdRipple } from '@angular2-material/core/core'; <== this line
@Component({
moduleId: module.id,
selector: 'nav-bar',
templateUrl: 'nav-bar.component.html',
styleUrls: ['nav-bar.component.css'],
directives: [
MdToolbar,
MdButton,
MdIcon,
MdRipple <== add here
],
providers: [
MdIconRegistry
]
})
export class NavBarComponent implements OnInit {
...
