在子字符串之前和之后插入一个元素

Question

如何在javascript/jQuery中使用正则表达式或替代形式在元素之间插入子串？

例如,我有以下字符串:

This is a string 015 with numbers 1486453 randomly 10 inserted between words 0954

如果我的正则表达式是找到所有数字,结果将如下:

This is a string <span>015</span> with numbers <span>1486453</span> randomly <span>10</span> inserted between words <span>0954</span>

Answer 1

var testStr = 'This is a string 015 with numbers 1486453 randomly 10 inserted between words 0954';    
var result = testStr.replace(/(\d+)/gi, '<span>$1</span>');
