搜索文本并用JavaScript替换

Question

示例我有这段代码：

<div class="description"> I make you smile. </div>

转换为：

<div class="description"> I make you think. </div>

注意：“微笑”被替换为“思考”

如何使用javascript jQuery替换它？可以改变几个单词吗？

Answer 1

var ele = $("div.description");                     //Let ele be target element
ele.html(ele.html().replace(/smile/gi,"think"));    //Replace the word in string,
                                                    // then put it back in.

.replace ：MDN
