An alternative approach in the context of Ionic would involve utilizing CSS properties to achieve the desired outcome. As outlined in the documentation, the ion-input
component includes a CSS property specifically for setting the text color
:
CSS Custom Properties
Name | Description
--------|------------------------
...
--color | Color of the input text
...
To implement this, you can define a new custom CSS property within the variables.scss
file like so:
:root {
// ...
--input-custom-color: blue; // default color for the input
}
Subsequently, within your page's styling, you can specify that the input should utilize this defined CSS property:
// my-page.page.scss
[name="addressSearch"] {
--color: var(--input-custom-color);
}
This setup allows you to easily modify the color by simply altering the value of the CSS property from within the component:
// Angular
import { Component, Inject } from "@angular/core";
import { DOCUMENT } from '@angular/platform-browser';
// Ionic
import { DomController } from '@ionic/angular';
@Component({
selector: "app-my-page",
templateUrl: "my-page.page.html",
styleUrls: ["my-page.page.scss"]
})
export class MyPage {
constructor(
private domCtrl: DomController,
@Inject(DOCUMENT) private document
) {}
public changeColor(aColor: string): void {
// Notify Ionic about DOM modifications
this.domCtrl.write(() => {
// Update the CSS property value
this.document.documentElement.style.setProperty('--input-custom-color', aColor);
});
}
}
By invoking this.changeColor('green');
, for instance, you can dynamically adjust the input's color in the UI. This method offers the benefit of centralized control over styling across various inputs within your application, eliminating the need to directly manipulate individual DOM elements.
It's worth noting that this approach is not limited to color changes alone but can be extended to customize other styles as well, whether through specific CSS properties or general attributes like
color: var(--input-custom-color);
