Question

假设有一个div包含内容和youtube链接。我想抓住youtube链接并嵌入它。

<div id="content"><p>Here is a cool video.  Check it out: http://www.youtube.com/watch?v=oHg5SJYRHA0</p></div>

我想获取链接并使用js（jquery）将其替换为嵌入代码。

更新1：

到目前为止，这是我的js：

    $("#content").each(function(){
    var allContent = $(this).html();
    //need regex to find all links with youtube in it, ovbiously it can't == youtube.com, but basically the link has to have youtube.com in it.
    if ($("a",allContent).attr("href") == "youtube.com" ) {
        // grab youtube video id
        /* replace link with <div id="yt-video">
        <object width="560" height="340"><param name="movie" value="http://www.youtube.com/v/429l13dS6kQ&hl=en&fs=1&"></param><param name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param><embed src="http://www.youtube.com/v/429l13dS6kQ&hl=en&fs=1&" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="560" height="340"></embed></object>
        </div>
        */
    }
});

我将content从id改为了类，因为我猜你有多个内容区域？

我确信有一种更有效的方法可以做到这一点，但这是我的尝试。注意我吮吸正则表达式，所以我拥有的尽可能接近，我确信有人可以帮助改进它，所以它不必替换里面的?v=每个循环。

HTML

<div class="content"><p>Here is a cool video.  Check it out: http://www.youtube.com/watch?v=oHg5SJYRHA0 and this one http://www.youtube.com/watch?v=fLBPsZVI8Gc&feature=player_embedded</p></div>
<div class="content"><p>Here is a cool video.  Check it out: http://www.youtube.com/watch?v=fLBPsZVI8Gc&feature=player_embedded</p></div>

脚本

$(document).ready(function(){
 // I added the video size here in case you wanted to modify it more easily
 var vidWidth = 425;
 var vidHeight = 344;

 $('.content:contains("youtube.com/watch")').each(function(){
  var that = $(this);
  var txt = $(this).html();
  // Tthis could be done by creating an object, adding attributes & inserting parameters, but this is quicker
  var e1 = '<obj'+'ect width="' + vidWidth + '" height="' + vidHeight + '"><param name="movie" value="http://www.youtube.com/v/';
  var e2 = '&hl=en&fs=1"></param><param name="allowFullScreen" value="true"></param><param name="allowscriptaccess" ' +
   'value="always"></param><em'+'bed src="http://www.youtube.com/v/';
  var e3 = '&hl=en&fs=1" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="' + vidWidth +
   '" ' + 'height="' + vidHeight + '"></embed></object> ';

  var vid = txt.match(/((\?v=)(\w[\w|-]*))/g); // end up with ?v=oHg5SJYRHA0
  if (vid.length) {
   $.each(vid, function(i){
    var ytid = this.replace(/\?v=/,'') // end up with oHg5SJYRHA0
    that.append( e1 + ytid + e2 + ytid + e3 ) 
   })
  }
 })
})

我会第一个承认它不漂亮但它有效。我还在this pastebin

中粘贴了此代码的工作版本

更新：我已经清理了一下代码，现在的样子（demo）：

$(document).ready(function(){
 // I added the video size here in case you wanted to modify it more easily
 var vidWidth = 425;
 var vidHeight = 344;

 var obj = '<object width="' + vidWidth + '" height="' + vidHeight + '">' +
     '<param name="movie" value="http://www.youtube.com/v/[vid]&hl=en&fs=1">' +
     '</param><param name="allowFullScreen" value="true"></param><param ' +
     'name="allowscriptaccess" value="always"></param><em' +
     'bed src="http://www.youtube.com/v/[vid]&hl=en&fs=1" ' +
     'type="application/x-shockwave-flash" allowscriptaccess="always" ' +
     'allowfullscreen="true" width="' + vidWidth + '" ' + 'height="' +
     vidHeight + '"></embed></object> ';

 $('.content:contains("youtube.com/watch")').each(function(){
  var that = $(this);
  var vid = that.html().match(/(?:v=)([\w\-]+)/g); // end up with v=oHg5SJYRHA0
  if (vid.length) {
   $.each(vid, function(){
    that.append( obj.replace(/\[vid\]/g, this.replace('v=','')) );
   });
  }
 });
});

我和fudgey在同一条轨道上，但是我甚至比他更吸引人，因此我已经“借用”了他的代码，直到那时为止。我做的一个改变是使用swfobject嵌入视频而不是手动编写嵌入代码。它只是意味着您必须将swfobject库添加到页面

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/swfobject/2.1/swfobject.js"></script>

HTML与fudgey的

相同

<div class="content"><p>Here is a cool video.  Check it out: http://www.youtube.com/watch?v=oHg5SJYRHA0 and this one http://www.youtube.com/watch?v=fLBPsZVI8Gc&feature=player_embedded</p></div>
<div class="content"><p>Here is a cool video.  Check it out: http://www.youtube.com/watch?v=fLBPsZVI8Gc&feature=player_embedded</p></div>

对javascript的小改动

$(function(){
    // I added the video size here in case you wanted to modify it more easily
    var vidWidth = 425;
    var vidHeight = 344;

    $('.content:contains("youtube.com/watch")').each(function(i){
        var that = $(this);
        var txt = $(this).html();       
        var vid = txt.match(/((\?v=)(\w[\w|-]*))/g); // end up with ?v=oHg5SJYRHA0
            if (vid.length) {
                $.each(vid, function(x){
                    var ytid = this.replace(/\?v=/,'') // end up with oHg5SJYRHA0   
                    var playerid = 'videoplayer_' + i + "_" + x; 
                    that.append("<div id='" + playerid + "'></div>");
                    swfobject.embedSWF("http://www.youtube.com/v/" + ytid, playerid, vidWidth, vidHeight, "8");                     
                })
            }
        })
    })

您需要使用以下内容获取div的内容：

var text = $("div#content p").html();  // or .text()

使用该文本，您可以使用字符串操作或正则表达式来查找URL。然后，您可以创建要添加的jquery内容：

var content = $('<a href="...">...</a>');

并使用jquery的操作方法将其添加到某些内容中，例如

var destination = $("body");
destination.append(content);
