問(wèn)題描述

srcmainwebappstaticca7ecd95-aa95-4da8-b369-92b66b566958icon.png

想截取從static開(kāi)始的字符串，請(qǐng)問(wèn)正則該如何寫(xiě)？感謝

也就是staticca7ecd95-aa95-4da8-b369-92b66b566958icon.png

另外由于url前半段可能會(huì)變動(dòng)，所以最好還是用正則的好

問(wèn)題解答

var str=’srcmainwebappstaticca7ecd95-aa95-4da8-b369-92b66b566958icon.png’;alert(str.replace(/^.*?(static.*?)$/ig, ’$1’));回答2：

split(’static’)[1] 這樣的嗎？ 還是必須用正則？

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

正則應(yīng)該用 static.* 就可以，下面是參考代碼

const regex = /static.*/g;const str = `srcmainwebappstaticca7ecd95-aa95-4da8-b369-92b66b566958icon.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}`); });回答5：

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

’srcmainwebappstaticca7ecd95-aa95-4da8-b369-92b66b566958icon.png’.match(/static.*/)// Output: [ 'staticca7ecd95-aa95-4da8-b369-92b66b566958icon.png']

這個(gè)問(wèn)題的亮點(diǎn)：
