Getting the src

[digitalrnd]

I'm trying to grab the src of the image generated, however, it only works after the 2nd click.

$("#apply").click( function(){
    var src = qrcode._oDrawing._elImage.currentSrc;
    console.log(src);
});

I'm using the src from the DOM and it works - even for a download link that grabs its href on click.
$(this).attr("href", $("#qrcode img").attr("src"));

i must wait img rendered before get scr

[phamhuyvn]

you can try. i still countinue test this
$("#text").on("blur", async () => {
const imgUrl = await qrcode.makeCode(document.getElementById("text").value);
console.log($('img').attr('src'));
});

    new QRCode(qrdiv, links)
    setTimeout(makeLink, 1000)

    function makeLink(){
      var qrlink = document.getElementById("downloadLink")
      var imgsrc = document.getElementsByTagName("img")[0].src
      qrlink.href = imgsrc
      qrlink.innerHTML = "Click here to downloar your QRcode"
      console.log(imgsrc)
    }

I added the timeout, so the src from the qrcode has enough time to load in order to be copied.

try this

const div = document.createElement('div');
new QRCode(div, "http://jindo.dev.naver.com/collie");
const src = div.children[0].toDataURL("image/png");
console.info('src', src);
