正则的截取匹配问题求助

Question

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

想截取从static开始的字符串，请问正则该如何写？感谢

也就是static\ca7ecd95-aa95-4da8-b369-92b66b566958\icon.png

另外由于url前半段可能会变动，所以最好还是用正则的好

Answer 1

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

Answer 2

split('static')[1] 这样的吗？ 还是必须用正则？

Answer 3

str.slice(str.search(/static/));

Answer 4

正则应该用 static.* 就可以，下面是参考代码

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}`);
    });

Answer 5

'srcmainwebappstaticca7ecd95-aa95-4da8-b369-92b66b566958icon.png'.split('static')[1]

Answer 6

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

// Output: 
[
  "static\\ca7ecd95-aa95-4da8-b369-92b66b566958\\icon.png"
]

var url='src\\main\\webapp\\static\\ca7ecd95-aa95-4da8-b369-92b66b566958\\icon.png';
var p=/\bstatic\b.*$/;
var result=url.match(p)[0];
