我有两个对象,用户和信息。
我打算将用户显示在不同的列中(对他们进行个性化设置),并且在每个用户中,我打算在info对象中放置用户ID与IDUser相同的相应信息。基本上,我打算分别在每个用户的列表中显示Obejto Info信息。
目前我有两个列表(用户和信息),我想在垂直和水平放置它们之间进行拖放,但是没有成功。
有人可以帮助我解决此问题,以便将卡片从一列传递到另一列(从用户到用户)。
示例:我打算在名称为Name1的列中放置文本为“名称2”的扩展卡。
谢谢

答案 0 :(得分:1)
您可以对方法进行多种更改以解决此问题:
var labelArray = document.querySelectorAll("*[aria-label]");
var labelText = labelArray.length;
for (var i = 0; i < labelText; i++) {
console.log(labelArray[i]);
}
个项目的数组。UserInfo
的容器元素上使用cdkDropListGroup
仅此而已!
cdkDropList
import {
Component
} from "@angular/core";
import {
CdkDragDrop,
moveItemInArray,
transferArrayItem
} from "@angular/cdk/drag-drop";
@Component({
selector: "my-app",
templateUrl: "./app.component.html",
styleUrls: ["./app.component.css"]
})
export class AppComponent {
Users = [{
id: 1,
name: "Name1",
items: [{
idUser: 1,
text: "Expand1"
}, {
idUser: 1,
text: "Expand11"
}]
},
{
id: 2,
name: "Name2",
items: [{
idUser: 2,
text: "Expand2"
}, {
idUser: 2,
text: "Expand22"
}]
},
{
id: 3,
name: "Name3",
items: [{
idUser: 3,
text: "Expand33"
}, {
idUser: 3,
text: "Expand33"
}]
}
];
drop(event: CdkDragDrop < string[] > ) {
if (event.previousContainer === event.container) {
moveItemInArray(
event.container.data,
event.previousIndex,
event.currentIndex
);
} else {
transferArrayItem(
event.previousContainer.data,
event.container.data,
event.previousIndex,
event.currentIndex
);
}
}
}
