我有一个我循环的数组。我的对象包括颜色。 我想循环数组并使用内联CSS动态设置颜色。
我试过了:
[ngStyle]="{ 'color': 'item.value'}"
[style.color]={{item.value}}
[style.color]="{{item.value}}"
如何设置颜色?
export class ColorSelectorComponent {
private color: string = "rgb(236,64,64)";
private color2: string = "rgb(236,64,64)";
private color3: string = "rgb(236,64,64)";
private color4: string = "rgb(236,64,64)";
private color5: string = "rgba(45,208,45,1)";
private color6: string = "#1973c0";
private color7: string = "#f200bd";
private arrayColors: any = {};
private selectedColor: string = 'color';
constructor(private cpService: ColorPickerService) {
console.log(this.arrayColors);
this.arrayColors['color'] = '#2883e9';
this.arrayColors['color2'] = '#e920e9';
this.arrayColors['color3'] = 'rgb(255,245,0)';
this.arrayColors['color4'] = 'rgb(236,64,64)';
this.arrayColors['color5'] = 'rgba(45,208,45,1)';
}
}
我的compontent HTML
<ul>
<li *ngFor="let item of arrayColors | keys">
<div class="color-drop" [style.color]="{{item.value}}" ></div>
Key: {{item.key}}, value: {{item.value}}
</li>
</ul>

以下是3种方式
<p [style.color] = "result > 30 ? 'blue' : 'green'"> Hello Color World! </p>
<p bind-style.color = "result > 30 ? 'blue' : 'green'"> Hello Color World! </p>
<p style.color = "{{result > 30 ? 'blue' : 'green'}}"> Hello Color World! </p>
