我尝试设置<ion-select>
输入标签的样式,但无法使其正常工作。似乎ionic会自动将ng-invalid
类添加到ion-select
DOM元素,但输入的<label>
是DOM的上游,所以我无法设置样式。
我的HTML
<ion-item>
<ion-label>Type of Weigh In</ion-label>
<ion-select [(ngModel)]="check_in.type_of_weighin" name="type_of_weighin" interface="action-sheet" required #type_of_weighin="ngModel">
<ion-option value="standard">Standard</ion-option>
<ion-option value="LM">Limited Maintenence</ion-option>
<ion-option value="FM">Full Maintenence</ion-option>
</ion-select>
</ion-item>
Renderd DOM:
<ion-item class="item item-block item-ios item-select input-has-value">
<div class="item-inner">
<div class="input-wrapper">
<ion-label class="label label-ios" id="lbl-103">Type of Weigh In</ion-label>
<ion-select interface="action-sheet" name="type_of_weighin" required="" class="select select-ios ng-untouched ng-pristine ng-invalid">
<div class="select-placeholder select-text"></div>
<div class="select-icon">
<div class="select-icon-inner"></div>
</div>
<button aria-haspopup="true" class="item-cover" ion-button="item-cover" id="sel-103-0" aria-labelledby="lbl-103" aria-disabled="false" style="transition: none;"></button>
</ion-select>
</div>
</div>
<div class="button-effect"></div>
</ion-item>
是否有其他方式来设置<label>
?

鉴于离子重新格式化,我不知道用css直接做的方法,但你可以附加一些eventListeners并根据更改进行更新。

<ion-item>
<ion-label [class.is-invalid]="inputsInvalid.type_of_weighin">Type of Weigh In</ion-label>
<ion-select [(ngModel)]="check_in.type_of_weighin" name="type_of_weighin" interface="action-sheet" required #type_of_weighin="ngModel" (change)="checkValid($event)">
<ion-option value="standard">Standard</ion-option>
<ion-option value="LM">Limited Maintenence</ion-option>
<ion-option value="FM">Full Maintenence</ion-option>
</ion-select>
</ion-item>
<强> TS 强>
inputsInvalid = {};
checkValid(e) {
const el = e.target;
inputsInvalid[el.id] = el.classList.contains('ng-invalid');
}

ion-label.is-invalid {
...
}
希望这是有道理的。
