Question

所以，我有以下代码：

<a type="button" class="btn btn-sm btn-primary btn-link" (click)="show = !show">Toggle</a>

但是当代码呈现时，HTML就是它在开发控制台中的样子

<a _ngcontent-c5="" class="btn btn-sm btn-primary btn-link" type="button">Toggle</a>

我已经尝试过将其作为按钮，这就是我得到的...

<button _ngcontent-c5="" class="btn btn-sm btn-primary btn-link" type="button">Toggle</button>

为什么会这样？

我正在使用的代码来自此Stackblitz链接：

https://stackblitz.com/edit/minimum-angular-code-for-a-transition?file=src%2Fapp%2Fapp.component.html

这是我的设置：

Angular CLI: 1.7.4
Node: 8.11.1
OS: win32 x64
Angular: 5.2.11
... animations, common, compiler, compiler-cli, core, forms
... http, platform-browser, platform-browser-dynamic
... platform-server, router

@angular/cdk: 5.2.4
@angular/cli: 1.7.4
@angular/language-service: 4.4.7
@angular/material: 5.2.5
@angular-devkit/build-optimizer: 0.3.2
@angular-devkit/core: 0.3.2

更新

我已经编写了一个可以正常工作的函数，但是我无法定义...这是从.ts文件顶部开始的代码的迷你版本：

HTML

<button type="button" class="btn btn-sm btn-primary btn-link" (click)="showHidePaperroll(false)">Toggle</button>

.TS文件

此开始于builder（）{}

下

public thePaperRoll: HTMLElement;

ngAfterViewInit() {
    this.thePaperRoll = document.querySelector(".box") as HTMLElement;
}


showHidePaperroll(what: boolean) {
    console.log("In Show Hide paperroll");
    let paperBox: any = "";
    paperBox = document.getElementById(".box") as HTMLImageElement;

    if (what === false) {
      paperBox = this.thePaperRoll.style.opened;
      console.log("PaperBox: ", paperBox);
    } else {
      paperBox = this.thePaperRoll.style.opened;
      console.log("PaperBox: ", paperBox);
    }

}

CSS

.box {
  background-color: #FFCC55;
  max-height: 0px;
  overflow-y: hidden;
  transition: ease-in-out 500ms max-height;
}

.box.opened {
  max-height: 500px;
  transition: ease-in-out 700ms max-height;
}

Angular 5删除html
