[英]Disable certain ng-template items in p-dropdown
I have a p-dropdown
contructed with ng-template
(this dropdown presents Languages that can be selected.) I need the languages that have been already selected, to be disabled
.我有一个用ng-template
构建的p-dropdown
(这个下拉列表显示可以选择的语言。)我需要已经选择的语言,要disabled
。
This is my dropdown:这是我的下拉列表:
<p-dropdown
[styleClass]="'form-control'"
[options]="languages"
optionValue="languageID"
formControlName="languageID"
appendTo="body"
(onChange)="onLanguageChanged(languagesFormGroup, $event.value)">
<ng-template let-item pTemplate="selectedItem">
<img src="{{item.icon}}"><span>{{item.name}} {{item.languageID}}</span>
</ng-template>
<ng-template let-item pTemplate="item">
<img src="{{item.icon}}"><span>{{item.name}} {{item.languageID}}</span>
</ng-template>
</p-dropdown>
I need specific pTemplate="item"
to be disabled.我需要禁用特定pTemplate="item"
。 I tried with angular's disable
, i tried with ng-disable
, with ngIf
, with [att.disabled]="expression(item)"
, nothing works.我尝试使用 angular 的disable
,我尝试使用ng-disable
,使用ngIf
,使用[att.disabled]="expression(item)"
,没有任何效果。
Is there any way to achieve what I need?有什么办法可以达到我的需要吗? Please help.请帮忙。
Thanks a lot in advace非常感谢提前
So I found the correct way to do it.所以我找到了正确的方法。 I added a disabled
property on my languages
collection.我在我的languages
集合中添加了一个disabled
属性。 I set disabled = true
whenever a language is selected and the ng-template
does the rest by itself. I set disabled = true
whenever a language is selected and the ng-template
does the rest by itself. No further code needed.无需进一步的代码。
Thanx everyone for their suggestions!感谢大家的建议!
