js replace 替换问题

Question

想把中文的【】替换成<span></span>

想要输出的效果是：
Visit<span>Microsoft</span>!

但是页面输出的效果却是这样的：

请教各位大神，这该怎么解决？

Answer 1

replace不会改变原来的字符串，你应该

    var aaa = 'Visit【Microsoft】!'
   var bbb = aaa.replace(/【/,'<span>').replace(/】/,'</span>');
   document.write(bbb)

建议这样做

 var aaa = 'Visit【Microsoft】!'
       var bbb = aaa.replace(/【()】/,'<span>$1</span>');
        console.log(bbb);

Answer 2

let str = 'Visit 【Microsoft】!';
document.write(str.replace(/【/,'<span>').replace(/】/,'</span>'));

Answer 3

var str = "Visit microsoft 【】";
var newStr = str.replace("microsoft","<span>microsoft</span>").replace('【】','');
document.write(newStr);

Answer 4

（>_<）等答案好了，document.write用也出不来<span>
