我正在使用PrimeNg的上下文菜单v6.0.1,问题是文档不清楚,我无法通过网络找到它如何将数据传递给命令功能,例如:
我在屏幕上呈现了10个对象,并且上下文菜单附加到所有这些对象,现在如果我单击菜单项我想获取上下文菜单所呈现的目标对象的id,如何实现?
<div id="block-container" *ngFor="let block of blocks">
<!-- where to attach this block object ??? -->
<p-contextMenu appendTo="body"
[target]="blockContextMenu"
[model]="contextMenuItems">
</p-contextMenu>
<div #blockContextMenu>
Some implementation...
</div>
</div>
以下是我的物品型号:
this.contextMenuItems = [
{
label: 'Trip Details',
command: (event) => {
// event doesn't contain anything useful,
// and only has the clicked menu item specific information.
}}
];
要使用primeng正确实现上下文菜单,您需要添加
[contextMenu]="cm"
例如,在您想要显示的元素中,您需要在div上使用上下文菜单
<div id="block-container" *ngFor="let block of blocks" [contextMenu]="cm"></div>
同样在p-contextMenu元素中,你需要从div中提到上下文菜单的变量
希望这可以帮助。
@ViewChild('copyMenu') copyMenu: ContextMenu;
onLinkRightClicked(content: string, e: any): void {
if (this.copyMenu) {
let model: MenuItem[] = [];
model.push({ label: 'Action', command: (event) => this.doAction(content) });
this.copyMenu.model = model;
this.copyMenu.show(e);
}
}
doAction(content){
// here
}
<div #blockContextMenu (contextmenu)="onLinkRightClicked(content, $event)">
Some implementation...
</div>
<p-contextMenu appendTo="body" #targetContextMenu>
</p-contextMenu>
