我正在尝试将 webjob 发布到 Azure，但出现一些如下错误。看起来是因为在“Out”之后的路径中它添加了两个反斜杠而不是一个（PubTmp\Out\\app_data）。

我正在尝试访问 Angular2 中的 div，如下所示：

import { Component, ViewChild, ElementRef, AfterContentInit } from '@angular/core';

@Component({
    selector: 'main',
    template: `
    <div  #target class="parent">
        <div class="child">
        </div>
    </div>
  `
})

export class MainComponent implements AfterContentInit {
    @ViewChild('target') elementRef: ElementRef;

    ngAfterContentInit(): void {
        var child = this.elementRef.nativeElement.querySelector('div');
        console.log(child);
    }
}

但我得到以下异常：

异常：调用节点模块失败并出现错误：TypeError：this.elementRef.nativeElement.querySelector 不是函数

我是angular2的新手.我的代码是这样的:

import { Component, OnInit } from '@angular/core';

@Component({
   selector: 'main',
   template: `
    <div class="current">
    </div>
  `
})

export class MainComponent implements OnInit {
   ngOnInit(): void {
     //change the div class from current to next...
   }
}

我想把div类从'current'更改为'next'.

如果你让我知道最好的方法是什么,我是否合适？
