如何用javascript代码中的嵌入代码替换youtube/vimeo url？

我尝试用javascript代码中的嵌入代码替换youtube和vimeo url

我使用了以下代码：

示例1:

<div id="divContent"></div>

$("#divContent").html('http://www.youtube.com/watch?v=t-ZRX8984sc <br /> http://vimeo.com/82495711 <br /> http://youtu.be/t-ZRX8984sc');

$('#divContent').html(function(i, html) {
    return html.replace(/(?:http:\/\/)?(?:www\.)?(?:youtube\.com|youtu\.be)\/(?:watch\?v=)?(.+)/g, '<iframe width="200" height="100" src="http://www.youtube.com/embed/$1" frameborder="0" allowfullscreen></iframe>').replace(/(?:http:\/\/)?(?:www\.)?(?:vimeo\.com)\/(.+)/g, '<iframe src="//player.vimeo.com/video/$1" width="200" height="100" frameborder="0" webkitallowfullscreen mozallowfullscreen allowfullscreen></iframe>');

});

<div id="divContent">

    <br />
http://vimeo.com/82495711
    <br />

</div>

$('#divContent').html(function(i, html) {
    return html.replace(/(?:http:\/\/)?(?:www\.)?(?:youtube\.com|youtu\.be)\/(?:watch\?v=)?(.+)/g, '<iframe width="200" height="100" src="http://www.youtube.com/embed/$1" frameborder="0" allowfullscreen></iframe>').replace(/(?:http:\/\/)?(?:www\.)?(?:vimeo\.com)\/(.+)/g, '<iframe src="//player.vimeo.com/video/$1" width="200" height="100" frameborder="0" webkitallowfullscreen mozallowfullscreen allowfullscreen></iframe>');

});

我使用ajax从数据库中检索了一个数据。我需要使用javascript将带有html代码的数据插入到div中。如何将示例1修改为正确的代码？

在示例1中，将javascript代码更改为：

$('#divContent').contents()
    .filter(function(){
        return this.nodeType === 3;
     })
    .map(function(index, text){
        $(text).replaceWith(
            text.textContent.replace(/(?:http:\/\/)?(?:www\.)?(?:youtube\.com|youtu\.be)\/(?:watch\?v=)?(.+)/g, '<iframe width="200" height="100" src="http://www.youtube.com/embed/$1" frameborder="0" allowfullscreen></iframe>').replace(/(?:http:\/\/)?(?:www\.)?(?:vimeo\.com)\/(.+)/g, '<iframe src="//player.vimeo.com/video/$1" width="200" height="100" frameborder="0" webkitallowfullscreen mozallowfullscreen allowfullscreen></iframe>')
        );    
    })

$（'#divContent'）.contents（）
.filter（函数（）{
返回this.nodeType==3；
})
.map（函数（索引、文本）{
$（文本）。替换为(
text.textContent.replace（/（？：http:\/\/）（？：www\）（？：youtube\.com | youtu\.be）\/（？：watch\？v=）（.+）/g'，）。replace（/（？：http:\/\/）（？：www\）（？：vimeo\.com）\/（.+）/g'，）
);    
})

它现在应该可以工作了。

您可以查找除空格以外的任何内容，因为url后面可能会有更多的文本。可以这样做：（[^\]+）而不是（+.+）这里是一个示例：
