qrcode.js生成二维码

1.引入qrcode.jsqrcode.js

<script type="text/javascript" src="./qrcode.min.js"></script>

2.页面中盛放二维码的容器,以一个div为例

// 二维码中的信息 这里以自定义输入为例 具体看需求
<input name="text" id="text" value="">
// 给个id -- qrcode
<div id="qrcode" style="width:250px; height:250px;"></div>

3.调用方法

<script>
			var qrcode = new QRCode(document.getElementById("qrcode"), {
				width: 250,
				height:250 // 可以自定义二维码的高宽
			});
            function makeCode() {
				var elText = document.getElementById("text");

				if (!elText.value) {
					alert("Input a text");
					elText.focus();
					return;
				}

				qrcode.makeCode(elText.value);
			}
			makeCode();
</script>

在这里插入图片描述
