我正在尝试使用jQuery Nestable库,我必须将data-id和data-weight设置为我的列表元素。这是必需的列表架构:
<div class="dd" id="nestable">
<ol class="dd-list">
<li class="dd-item" data-id="10" data-weight="1">
<div class="dd-handle">Item 1</div>
</li>
<li class="dd-item" data-id="29" data-weight="2">
<div class="dd-handle">Item 2</div>
</li>
<li class="dd-item" data-id="58" data-weight="3">
<div class="dd-handle">Item 11</div>
</li>
</ol>
</div>
但是,每次我尝试为元素分配属性时,都会收到以下错误:
Can't bind to 'weight' since it isn't a known property of 'li'.
这是我的nestable.directive.ts:
@Directive({ selector: '[uiNestable]' })
export class NestableDirective {
constructor(el: ElementRef) {
$(el.nativeElement).nestable({
group: 1
});
}
}
感谢任何帮助。

尝试使用data-weight
绑定语法绑定到attr
属性。这可以这样做:
<li class="dd-item" data-id="10" [attr.data-weight]="1">
<div class="dd-handle">Item 1</div>
</li>
