ion-segament控件可以通过代码调用click事件

前提：

entrypage.html主容器的header 配置segament用于tab切换，主容器里面的content嵌套了好几个tab,然后这个tab里面有子组件。需要通过代码调用segament的点击事件。

<ion-header *ngIf="titleBar && titleBar!=={} "
    [ngClass]="{'isHeight': !isHeader, 'header-orange': titleBar.cssStyle === 'orange','header-white': titleBar.cssStyle === 'white'}"
    translucent="false">
    <ion-toolbar id="superToolbar"
        [ngClass]="{'isShow': isHeader,'isHide':!isHeader,'bg-image':showWaterImg, 'title-orange': titleBar.cssStyle === 'orange','title-transparent': titleBar.cssStyle === 'transparent','title-white': titleBar.cssStyle === 'white','bottom-line': (titleBar.cssStyle === 'white' || titleBar.cssStyle === undefined ) && titleBar.bottomLine !== false }">
        <ng-container *ngIf="titleBar.title &&  (!titleBar.title.layout || titleBar.title.layout === 'center')">
            <ion-title class="nav-title" *ngIf="titleBar.title">{{titleBar.title.labelName}}</ion-title>

通过子组件页面的声明周期监听处理点击事件：

  // tslint:disable-next-line:use-life-cycle-interface
  ngAfterViewChecked(): void {
    let currentTabStr = 'hometopSegmentBtn';
    if (this.tagData && this.tagData.currentTab) {
      currentTabStr += this.tagData.currentTab;
    } else {
      currentTabStr += '0';
    }
    if (document.getElementById(currentTabStr)) {
      const firstBtn = document.getElementById(currentTabStr);
      firstBtn.click();
    }
  }
