使用 $ c>：

  $（'p'）。each（function（）{
 this.innerHTML = this .innerHTML.replace（/ \bok\b / g，'< img src =ok.pngalt =good word/>'）
}）
 

我使用 / \bok\b / code>令牌将不匹配。 \b 表示字边界。

I have this code in my body :

<p>
    hello ok hello no
<p>

<p>
    ok hello ok ko 
<p>    

I want to replace for each <p> the text 'ok' by <img> tag <img src="ok.png" alt="good word"/>

Is it possible to do this ?

Note : i must apply this function for others texts who can contain apostrophe and/or quote

Use each:

$('p').each(function() {
    this.innerHTML = this.innerHTML.replace(/\bok\b/g, '<img src="ok.png" alt="good word"/>')
})

I used /\bok\b/ so that something like token won't match. \b means "word boundary."

Here's a fiddle.
