为什么onclick="window.history.back()"工作和角度ng-click="window.history.back()"没有？

我正在练习angular2,我真的很新.我构建了2个组件 - 父组件及其子组件.当我试图将一些参数从父组件传递给它的子组件时,我得到'错误:输入未定义'.有人可以帮助我,因为我无法看到我做错了什么.

export class SquadComponent{
  @Input() selectedteam;
}

我的傻瓜

I\'m trying to build an html document and for some reason Hebrew letters are not shown correctly. Instead, all I see are these question marks \xef\xbf\xbd\xef\xbf\xbd\xef\xbf\xbd\xef\xbf\xbd\xef\xbf\xbd.\nI can see Hebrew letters in other websites. The html document is local, meaning I open it from my desktop.\nAny ideas?\nThanks =)

我有一个div,在div里面我有一个'svg'元素.我想放大,每次点击'svg'元素的'scale'值都会增加,从而产生缩放效果.但是,由于某种原因,当内部'svg'的比例增大时,父div的滚动条没有被修改.这个问题只出现在Chrome中,在IE中我实际上得到了想要的结果.

小提琴的例子

var elementToScale = document.getElementById('svg');
var scale = 1;

document.getElementById('zoom').addEventListener('click', function() {
  scale += 0.1
  elementToScale.style.transform = "scale(" + scale + ")";
});

div {
  border: 1px solid black;
  width: 400px;
  height: 400px;
  overflow: scroll;
}
svg {
  border: 1px solid black;
}

<div>
  <svg width=300px height=300px id="svg">
    <rect width=200 height=200 x=50 y=50 fill="red" />
  </svg>
</div>
<br>
<button id="zoom">
  ZoomIn
</button>
