Question

在ng-bootstrap站点上，Modal component-> Api上有一条信息，表明模态具有属性conatainer，描述为“ An element to which to attach newly opened modal windows”。这是否意味着我可以将打开的模式直接附加到HTML网站上指定的div id元素上？

如果是这样，如何在Angular项目上实现？在我的项目中，我在modal-basic.html中添加了以下代码：

<div id="test" class="col-6">Some text</div>

还添加了属性容器：

this.modalService.open(content, {container: 'test',ariaLabelledBy: 'modal-basic-title'}).result.then((result) => {
  this.closeResult = `Closed with: ${result}`;
}, (reason) => {

  this.closeResult = `Dismissed ${this.getDismissReason(reason)}`;
});

但是我收到一个错误：

NgbdModalBasic.html:28 ERROR Error: The specified modal container "test" was not found in the DOM.
    at NgbModalStack.push../node_modules/@ng-bootstrap/ng-bootstrap/fesm5/ng-bootstrap.js.NgbModalStack.open (ng-bootstrap.js:6417)

能帮我吗？

指定容器元素时，您需要传入元素或选择器或两者的组合。在您的情况下，您想访问ID为test的元素。容器属性应设置为“ #test”。

this.modalService.open(content, {container: '#test',ariaLabelledBy: 'modal-basic-title'}).result.then((result) => {
  this.closeResult = `Closed with: ${result}`;
}, (reason) => {

  this.closeResult = `Dismissed ${this.getDismissReason(reason)}`;
});
