Set src attribute of an image to another image using jQuery in ASP.Net

How can I assign the src property of an image to another src of another image on my web page

I want to assign this result img.src = jQuery ('# Image1'). Attr ("src");

To another image that I call salida with jquery as follows:

jQuery('#salida').attr("src") = jQuery('#Image1').attr("src");

But it doesn't work for me, how I can change the src of the output image using jquery taking the value of from image1's src

            jQuery('#btnCrop').click(function () {
                var x1 = jQuery('#imgX1').val();
                var y1 = jQuery('#imgY1').val();
                var width = jQuery('#imgWidth').val();
                var height = jQuery('#imgHeight').val();
                var canvas = jQuery("#canvas")[0];
                var context = canvas.getContext('2d');
                var img = new Image();
                
                img.onload = function () {
                    canvas.height = height;
                    canvas.width = width;
                    context.drawImage(img, x1, y1, width, height, 0, 0, width, height);
                    jQuery('#imgCropped').val(canvas.toDataURL());
                    jQuery('#btnUpload').show();
                };
                img.src = jQuery('#Image1').attr("src");
                jQuery('#salida').attr("src") = jQuery('#Image1').attr("src");
            });
