javascript - 正则表达式用替换模式修改匹配

Question

字符串：

'some text [2string] some another [test] and [test-]'.match(/\[\D+?\]+/g);

如何修改我编写的正则表达式以匹配 [2string]（带整数的字符串），并将所有匹配替换为 [] 之间的引用值，因此它们变为 ['2string']

谢谢！

Answer 1

Try this:

var txt = 'some text [2string] some another [test] and [test-]';
var spl = txt.split('[').join("['").split(']').join("']");
console.log(spl);

or use simple String.replace().
