问题描述
我尝试在带有ngFor的pTooltip中显示字符串列表.
I try to display a list of string in a pTooltip with an ngFor.
<div pTooltip="Liste: <span *ngFor='let code of {{codes}}'>{{code}}</span>" [escape]="false"></div>
或
<div pTooltip="Liste: <ng-template ngFor let-code [ngForOf]="codes"><span>{{code}}</span></ng-template>" [escape]="false"></div>
可以使用[escape] ="false"进行思考,但是我什么都没有.
Thinking with [escape]="false" will be ok but i have nothing.
请问有人有主意吗?
谢谢
推荐答案
您可以通过设置 [escape] ="false"
并使用pTooltip这样的属性绑定来显示pTooltip中的HTML内容 [pTooltip] .在此示例中,我使用了< span>
标记,也可以使用< ul>
显示字符串列表.
You can show HTML content in pTooltip by setting [escape]="false"
and using property binding with pTooltip like this way [pTooltip]
. I have used <span>
tag in this example , you can also use <ul>
to show a list of strings.
这是完整的工作代码:
Component.ts文件:
import { Component } from '@angular/core';
@Component({
selector: 'my-app',
templateUrl: 'app/app.template.html'
})
export class AppComponent {
isDisabled = false;
isTooltipDisabled = false;
codes:any[] = ['test1','test2','test3'];
disable() {
this.isTooltipDisabled = true;
this.isDisabled = true;
}
showList():string{
let temp:string = ``;
for(let code of this.codes){
temp+=`<span>${code}</span><br>`;
}
return temp;
}
}
组件HTML:
<h2>PrimeNG Issue</h2>
<div>
<div [pTooltip]="showList()" [escape]="false" tooltipPosition="bottom">This is sample</div>
</div>
我使用了pTooltip的属性绑定来将方法 showList()
的返回值显示为HTML字符串.
I have used property binding with pTooltip to show the return value of method showList()
as HTML string.
这是一个可行的示例:
