Answer 1

你可以做這樣的事情。

<input type="text" name="input1" id="input1">
<button class="btn btn-primary" onclick="myFunction()" >SAVE</button>

<script>
function myFunction() {
      var xml = new XMLSerializer().serializeToString(svg);
      let str = `data:image/svg+xml;base64,${window.btoa(new XMLSerializer().serializeToString(document.getElementById("svg")))}`;
      console.log(str); // para sa base 64 ng image 

      document.getElementById("input1").value=str;
}
</script>
