Javascript 如何将变量从typescript传递到嵌入式JS?_Javascript_Angular_Typescript - Fatal编程技术网

Javascript 如何将变量从typescript传递到嵌入式JS?

Javascript 如何将变量从typescript传递到嵌入式JS?,javascript,angular,typescript,Javascript,Angular,Typescript,我在angular项目中使用JavaScript,无法使用变量来实现动态行为,有没有办法使用从服务接收的this.testID,然后将其传递给下面的JS代码,我当前的静态值为1234。请告诉我您的建议/解决方案 public ngOnInit() { this.testID = this.someSettings.testID; // this is the ID to be passed to below JS } public onClicked() { let

我在angular项目中使用JavaScript,无法使用变量来实现动态行为,有没有办法使用从服务接收的this.testID,然后将其传递给下面的JS代码,我当前的静态值为1234。请告诉我您的建议/解决方案

public ngOnInit() {
    this.testID = this.someSettings.testID; // this is the ID to be passed to below JS 
  }

  public onClicked() {
    let script = this._renderer2.createElement('script');
    script.type = `text/javascript`;
    script.text = `{          
      window._fs = window._fs || [];
      _fs.push(['cid', 'something']);
      _fs.push(['uid', '1234']); // here is where I want the ID from above to be passed instead of 1234
    }`;
    this._renderer2.appendChild(this._document.body, script);
  }

谢谢您

您的整个
脚本。文本
是反勾号,即一种支持多行和解释值的字符串类型:

script.text = `{  // <--- Starting backtick        
      window._fs = window._fs || [];
      _fs.push(['cid', 'something']);
      _fs.push(['uid', ${this.testID}]); //  <-- Interpreted value
}`;  // <--- Ending backtick 

script.text=`{/
\u fs.push(['uid',this.testID])
?这不起作用,我已经试过了。它在一个反勾字符串中,试一下
`u fs.push(['uid',${this.testID}])`
@JeremyThille这会导致它无法识别出[u fs],它说“找不到名称”\u fs.”你不需要反勾号是什么意思?你的字符串已经在反勾号中,你自己使用反勾号发布了我的解决方案
