如何使用JavaScript在網頁加載時動態生成并顯示圖片？

我想從一個數組中獲取圖像，并在瀏覽器窗口加載后顯示在網頁上。這就是我所做的。

const players = [
    {
     photo: 'img/photo0.jpeg'
    },
    {
     photo: 'img/photo1.jpeg'
    },
    {
     photo: 'img/photo2.jpeg'
    }]

// This is the function I built to do that.
    function() {

      for(i = 0; i < players.lengh; i++;){
      }
    }

您可以通過窗口對象訪問onLoad方法。

window.onload = function() {
  // Whatever you want to do on load
};

let box = document.querySelector(".box");

      const players = [
        {
          photo: "img/photo0.jpeg",
        },
        {
          photo: "img/photo1.jpeg",
        },
        {
          photo: "img/photo2.jpeg",
        },
      ];

      function displayImages() {
        // Empty the box element so, that if some changes made to this element will reflect new data
        box.innerHTML = ``;
        // create template to show
        let domStr = ``;
        for (let img of players) {
        //dynamic creating images in template str
          domStr += `
                  <img src=${img.photo} width=200 height=200>
                  `;
        }

        // after loop concatenates str with img in loop make it attach with the element
        // document.body.innerHTML = domStr;
        box.innerHTML = domStr;
      }

      //   On window load calling the function
      window.addEventListener("load", (event) => {
        displayImages();
      });
