简单高亮

产品导览并非 Driver.js 的唯一用例。你可以使用它来高亮页面上的任何元素，并显示带有描述的弹出窗口。这对于向用户提供上下文帮助很有用，例如帮助用户填写表单或解释某个功能。

¥Product tours is not the only usecase for Driver.js. You can use it to highlight any element on the page and show a popover with a description. This is useful for providing contextual help to the user e.g. help the user fill a form or explain a feature.

以下示例展示了如何高亮元素并简单地显示弹出窗口。

¥Example below shows how to highlight an element and simply show a popover.

以下是上述示例的代码：

¥Here is the code for above example:

const driverObj = driver({
  popoverClass: "driverjs-theme",
  stagePadding: 4,
});

driverObj.highlight({
  element: "#highlight-me",
  popover: {
    side: "bottom",
    title: "This is a title",
    description: "This is a description",
  }
})

你还可以使用它来显示一个简单的模态框，而不高亮任何元素。

¥You can also use it to show a simple modal without highlighting any element.

以下是上述示例的代码：

¥Here is the code for above example:

const driverObj = driver();

driverObj.highlight({
  popover: {
    description: "<img src='https://i.imgur.com/EAQhHu5.gif' style='height: 202.5px; width: 270px;' /><span style='font-size: 15px; display: block; margin-top: 10px; text-align: center;'>Yet another highlight example.</span>",
  }
})

关注下面的输入，看看弹出窗口是如何显示的。

¥Focus on the input below and see how the popover is shown.

以下是上述示例的代码。

¥Here is the code for the above example.

const driverObj = driver({
  popoverClass: "driverjs-theme",
  stagePadding: 0,
  onDestroyed: () => {
    document?.activeElement?.blur();
  }
});

const nameEl = document.getElementById("name");
const educationEl = document.getElementById("education");
const ageEl = document.getElementById("age");
const addressEl = document.getElementById("address");
const formEl = document.querySelector("form");

nameEl.addEventListener("focus", () => {
  driverObj.highlight({
    element: nameEl,
    popover: {
      title: "Name",
      description: "Enter your name here",
    },
  });
});

educationEl.addEventListener("focus", () => {
  driverObj.highlight({
    element: educationEl,
    popover: {
      title: "Education",
      description: "Enter your education here",
    },
  });
});

ageEl.addEventListener("focus", () => {
  driverObj.highlight({
    element: ageEl,
    popover: {
      title: "Age",
      description: "Enter your age here",
    },
  });
});

addressEl.addEventListener("focus", () => {
  driverObj.highlight({
    element: addressEl,
    popover: {
      title: "Address",
      description: "Enter your address here",
    },
  });
});

formEl.addEventListener("blur", () => {
  driverObj.destroy();
});
