模态<clr-modal>生活圈挂钩

Question

我如何检测模态内容可见？ 我正在尝试为模式内部的元素初始化tinymce。但是在打开模式之前调用了ngAfterViewInit（）-因此该元素在页面上仍然不存在。

delayedinit() {
    setTimeout(() => { ///<== hack to be sure that textarea already rendered
        this.init();
    }, 5000);
}

public init() {
    tinymce.init({
        selector: '#' + this.elementId,
        plugins: ['link', 'table'],
        skin_url: '../assets/skins/lightgray',
        setup: editor => {
            this.editor = editor;
            editor.on('keyup change', () => {
                const content = editor.getContent();
                this.onEditorContentChange.emit(content);
            });
        }
    });
}

ngAfterViewInit() {
    this.init(); //<==this called when element isn't rendered
}
