jQuery：基于src收集img标记，然后替换它们

Posted 2021-02-24

This two liner is powerful. It shows you how to find images on a page based on the source (src) and replace them with another image.

var img = $(".columnLeft").find("img[src='/path/to/existing/image/file.png']");
$(img).attr("src", "/path/to/new/image/file.png" );
