如何使用常规exp？

用“span”替换文本中的每个单词

var text = "1:393 1:838 3:936 1:998 1:1398 1:1652 1:1718 1:1806"

final op = "<span class="word">1:393</span><span class="word">1:838</span><span class="word">3:936</span><span class="word">1:998</span><span class="word">1:139</span>...."

Answer 1

如果分隔符始终是单个空格，则不需要正则表达式，只需分隔空格（或\b如果你想要一个正则表达式），添加一些标记，然后重新加入。

var text = "1:393 1:838 3:936 1:998 1:1398 1:1652 1:1718 1:1806";

var op = text.split(' ').map(function(w) {
    return '<span class="word">' + w + '------</span>';
}).join('');

document.body.innerHTML = op;

.word {color : red}

Answer 2

var op = '<span class="word">' + text.split(' ').join('</span><span class="word">') + '</span>'

Answer 3

使用String#replace。

const text = "1:393 1:838 3:936 1:998 1:1398 1:1652 1:1718 1:1806";
const result = text.replace(/\d:\d+/g, '<span class="word">$&</span>');

console.log(result);

Answer 4

这是您所需要的（https://jsfiddle.net/6r005vgf/3/）：

var text = "1:393 1:838 3:936 1:998 1:1398 1:1652 1:1718 1:1806";

//var final = "<span class='word'>1:393</span><span class='word'>1:838</span><span class='word'>3:936</span><span class='word'>1:998</span><span class='word'>1:139</span>....";

var final_test = "<span class='word'>" + text.replace(/\s+/g, "</span><span class='word'>") + "</span>";

//alert(final);
alert(final_test);
