Download multiple files at once - js

We can use window.location.href = 'url' to download files, or use a tag, but if you download multiple files at a time, this method will not work, you can use the following methods to achieve

// 下载多个模版
    downloadBtn () {
      const data = [
        'url1',
        'url2'
      ]
      for (let i = 0; i < data.length; i++) {
        const iframe = document.createElement('iframe')
        iframe.style.display = 'none'
        iframe.style.height = 0
        // url自己进行指定
        iframe.src = data[i]
        document.body.appendChild(iframe)
        // 不能马上将iframe进行删除，否者也会出现马上取消的情况
        setTimeout(() => {
          iframe.remove()
        }, 5 * 1000)
      }
    }
