jquery - jquery用未知部分替换字符串

Question

我得到了这段代码。

    imgsrc = imgsrc.replace('-UNKNOWN_NUMBERx50.jpg','.jpg');

那么如何更改它以使其正确替换该值，无论它是“80x50.jpg”还是“120x50.jpg”或其他任何东西？

提前致谢 ;）

Answer 1

For a regex replace, you need to use the forward slash delimiters like this and escape meta characters if there are any, and in this case, you have the dot .:

imgsrc = imgsrc.replace(/-\d+x50\.jpg/,'.jpg');
                        ^            ^

See if that works now.

\d+ means 1 or more digits. If you want to have a digit without a leading 0, use something like this instead of \d+: [1-9]\d*
