方法一：str拼接

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
    <style>
        .item{
            width: 300px;
            height: 300px;
        }
        .item img{
            width: 100%;
        }
        #allPic .item {
            float: left;
        }
    </style>
<script>
        function init() {
            var arr1 = ["1.jpg", "2.jpg", "3.jpg", "4.jpg", "5.jpg", "6.jpg"]
            var arr2 = ["联想(Lenovo)", "华硕(ASUS)", "Dell", "Hp", "Mac", "XiaoMi"]
            var str = "";
            for (var i = 0; i < arr1.length; i++) {
                str += "<div class='item'>";
                str += "<div><img src='image2/" + arr1[i] + "'></div>";
                str += "<p>" + arr2[i] + "</p>";
                str += "</div>"
            }
            document.getElementById("allPic").innerHTML = str;
        }
    </script>
</head>
<body onload="init()">
<section id="allPic">
</section>
</body>
</html>

这里写图片描述

方法二：
结构：

<section id="allPic">
   <!--  <div>
        <img src="images/1.jpg" alt="">
        <p>联想(Lenovo)</p>
    </div>  -->
</section>

代码如下：

    <style>
        div{
           width: 300px;
            height: 300px;
        }
        div img{
            width: 100%;
        }

        #allPic div{
            float: left;
        }
    </style>

<script>
        function init() {
            var arr1 = ["1.jpg", "2.jpg", "3.jpg", "4.jpg", "5.jpg", "6.jpg"]
            var arr2 = ["联想(Lenovo)", "华硕(ASUS)", "Dell", "Hp", "Mac", "XiaoMi"]
                var section = document.getElementById("allPic")
            for (var i = 0; i < arr1.length; i++) {
                var node = document.createElement("div")
                node.innerHTML = "<img src='image2/" + arr1[i] + "'> <p>" + arr2[i] + "</p>"
                section.appendChild(node);
            }
        }

    </script>

方法三：

<script>
        function init() {
            var arr1 = ["1.jpg", "2.jpg", "3.jpg", "4.jpg", "5.jpg", "6.jpg"]
            var arr2 = ["联想(Lenovo)", "华硕(ASUS)", "Dell", "Hp", "Mac", "XiaoMi"]
            var section = document.getElementById("allPic")
            for (var i = 0; i < arr1.length; i++) {
                var div = document.createElement("div")
                var img = document.createElement("img")
                //img.src="images/"+arr1[i]
                img.setAttribute("src","image2/"+arr1[i]);
                div.appendChild(img);
                var p = document.createElement("p")
                var text=document.createTextNode(arr2[i])
                p.appendChild(text);
                div.appendChild(p);
                section.appendChild(div);
            }
        }
    </script>
