Question

jquery qrcode 怎么生成带logo的二维码

Answer 1

$('#output').qrcode({
width: 500,
height: 500,
text: trClick.utf16to8(localhref + "?" + qrCode),
imgWidth: 300/4, //图片宽
imgHeight: 300 / 4, //图片高\
src: "../img/icon.png"
});
$('#output').css('display', 'block');
var canvas = $('#output').find("canvas")[0];
try {//解决IE转base64时缓存不足，canvas转blob下载
var blob = canvas.msToBlob();
navigator.msSaveBlob(blob, qrCode + '.png');
} catch (e) {//如果为其他浏览器，使用base64转码下载
var url = canvas.toDataURL('image/jpeg');
$("#download").attr("download", qrCode + '.png')
$("#download").attr('href', url).get(0).click();
}
