如何在 Angular 的 CSS 中添加其他样式属性? [英] How can I add additional style properties in CSS in Angular?

问题描述

我有一个属性可以设置文本元素的字体大小.到目前为止我已经尝试过了:

I have a property which should set the font size of a text element. I've tried this so far:

<textarea 
  placeholder="Enter your TAX ID" 
  id="tax" 
  [(ngModel)]="tax_out" 
  [(ngModel)]="tax_in" 
  style="width: 100%; height: 100%; position: relative; bottom: 0px; fontsize: {{fontsize}}">
</textarea>

很遗憾没有成功.

我在 logcat 中得到了这个:

I get this in logcat:

"警告:清理不安全的样式值宽度:100%；高度:100%；位置:相对；底部:0px；字体大小:(见http://g.co/ng/security#xss)."

"WARNING: sanitizing unsafe style value width: 100%; height: 100%; position: relative; bottom: 0px; fontsize: (see http://g.co/ng/security#xss)."

"[WARN] TypeError: Cannot set property style of [object Object] which只有一个吸气剂"

"[WARN] TypeError: Cannot set property style of [object Object] which has only a getter"

推荐答案

如果只是单一样式，可以使用属性绑定:

If it's just a single style, you can use property binding for this:

<textarea [style.font-size.px]="fontsize" ... style="width: 100%; height: 100%; position: relative; bottom: 0px;"></textarea>

如果您需要设置更多信息，请查看 ngStyle 文档了解更多信息动态不止一种样式:

Please take a look at the ngStyle docs for more info if you need to set more than one style dynamically:

<some-element [ngStyle]="{'font-style': styleExp}">...</some-element>    
<some-element [ngStyle]="{'max-width.px': widthExp}">...</some-element>    
<some-element [ngStyle]="objExp">...</some-element>
