javascript - help with regular interception and matching problems

src\main\webapp\static\ca7ecd95-aa95-4da8-b369-92b66b566958\icon.png

I want to intercept the string starting from static. How should I write the regular expression? grateful

That is, static\ca7ecd95-aa95-4da8-b369-92b66b566958\icon.png

In addition, since the first half of the URL may change, it is best to use regular ones

    var str='src\\main\\webapp\\static\\ca7ecd95-aa95-4da8-b369-92b66b566958\\icon.png';
    alert(str.replace(/^.*?(static.*?)$/ig, '$1'));

    split('static')[1] Is this the case? Or do I need to use regular rules?

    You should use static.* for regular expressions. The following is the reference code

    const regex = /static.*/g;
    const str = `src\main\webapp\static\ca7ecd95-aa95-4da8-b369-92b66b566958\icon.png`;
    let m;
    
    while ((m = regex.exec(str)) !== null) {
        // This is necessary to avoid infinite loops with zero-width matches
        if (m.index === regex.lastIndex) {
            regex.lastIndex++;
        }
        
        // The result can be accessed through the `m`-variable.
        m.forEach((match, groupIndex) => {
            console.log(`Found match, group ${groupIndex}: ${match}`);
        });

    'src\main\webapp\static\ca7ecd95-aa95-4da8-b369-92b66b566958\icon.png'.match(/static.*/)
    
    // Output: 
    [
      "static\ca7ecd95-aa95-4da8-b369-92b66b566958\icon.png"
    ]
