javascript - 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：“微笑”改为“思考”

如何使用 javascript jQuery 替换它？可以换几个字吗？

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
