How to change the color of a div in code dynamically in ionic by using code?

推荐答案

如果只是单一样式，则可以使用属性绑定.在您的组件中:

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

public aColor: string = "#ccc";

然后在视图中:

<div [style.background-color]="aColor"></div>

如果需要设置更多信息，请查看 ngStyle 文档以获取更多信息.动态地一种样式:

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>
