Answer 1

使用URL openInNewTab 它將在新的瀏覽器選項卡中打開URL 。 如果您想在同一個選項卡中打開它，請刪除“_blank”。

const openInNewTab = (url) => {
    const newWindow = window.open(url, '_blank', 'noopener,noreferrer')
    if (newWindow) newWindow.opener = null
}

Answer 2

好吧，如果我理解正確，您是在嘗試單擊按鈕打開 URL 嗎？

如果這是正確的，在單擊處理程序中使用window.open('https://example.com', '_blank')將允許您在新選項卡中打開任何 URL。

Answer 3

首先，您需要使用find方法找到正確的 object，然后您可以使用 window.open 打開window.open

嘗試以下代碼： -

handleClick = () => {
    const apiUrl = "https://mocki.io/v1/b512f8b8-64ab-46e4-9e0c-9db538a0ad9e";
    if (this.state.checkbox) {
      fetch(apiUrl)
        .then((response) => response.json())
        .then((data) => {
          this.setState({ data: data });
          const urlData = data.find(element => element.id === 3); // filter data with id
          window.open(urlData.url, '_blank'); // open url here
        });
    } else {
      alert("check the radio!");
    }
  };
