默认情况下，dragula 将允许用户拖动任何容器中的元素并将其拖放到列表中的任何其他容器中。如果元素被放置在不是容器之一的任何地方，则该事件将根据 revertOnSpill 和 removeOnSpill 选项优雅地取消。
下面的示例允许用户将元素从左拖到右，从右拖到左。
在 HomePage.component.html 中创建代码
<div class="wrapper"> <div class="container master" [dragula]="'editor-bag'" [dragulaModel]="q1">
<div *ngFor="let item of q1" class="box">
{{item}}
</div>
</div>
<div class="container" [dragula]="'editor-bag'">
</div>
接下来，创建 HomePageComponent.ts。另外，需要设置带有以下签名的接受方法：（el，目标，源，兄弟）
import { DragulaService, DragulaDirective } from 'ng2-dragula/ng2-dragula';
import { Router, Route, ActivatedRoute } from '@angular/router';
import { Component, OnInit } from '@angular/core';
@Component({
selector: 'app-home-page',
templateUrl: './home-page.component.html',
styleUrls: ['./home-page.component.css'],
})
export class HomePageComponent implements OnInit {
q1 = [];
q2 = [];
static _debug: boolean = false;
_debug: boolean = HomePageComponent._debug;
constructor(private dragulaService: DragulaService, private router: Router, private route: ActivatedRoute) {
for (var i = 0; i < 10; i++) {
this.q1.push("1. <" + i + ">");
//this.q2.push("2. <" + i + ">");
}
dragulaService.setOptions('editor-bag', {
accepts: function (el, target, source, sibling) {
var fn_debug = true;
var acceptAll = false;
if (this._debug || fn_debug) {
console.log("accepts() start el, target, source, sibling");
console.log({ el, target, source, sibling });
}
if (target.classList.contains('master')) {
return false;
}
if (sibling == null) {
return (target.children.length == 0);
}
var name: string = el.innerText;
return false;
},
direction: 'vertical', // Y axis is considered when determining where an element would be dropped
copy: function (el, source) {
if (this._debug) {
console.log("copy() start");
console.log(el);
console.log(source);
console.log("copy() stop");
}
return source.classList.contains('master');
}, // elements are moved by default, not copied
copySortSource: false, // elements in copy-source containers can be reordered
revertOnSpill: false, // spilling will put the element back where it was dragged from, if this is true
removeOnSpill: true, // spilling will `.remove` the element, if this is true
mirrorContainer: document.body, // set the element that gets mirror elements appended
ignoreInputTextSelection: true // allows users to select input text, see details below
})
}
ngOnInit() {
this.dragulaService.drag.subscribe((value: any) => {
if (this._debug) {
console.log("drag start");
console.log(value);
console.log("drag stop");
console.log(`drag: ${value[0]}`);
}
// this.onDrag(value.slice(1));
});
this.dragulaService.drop.subscribe((value: any) => {
console.log(`drop: ${value[0]}`);
//this.onDrop(value.slice(1));
});
this.dragulaService.over.subscribe((value: any) => {
if (this._debug) { console.log(`over: ${value[0]}`); }
// this.onOver(value.slice(1));
});
this.dragulaService.out.subscribe((value: any) => {
if (this._debug) { console.log(`out: ${value[0]}`); }
//this.onOut(value.slice(1));
});
}
}
