js脚本，提取第一张图片：

//获取第一张图片
$('#autolitpic').click(function (){
if($(this).attr('checked')){
$(this).attr('checked',false);
}else {
$(this).attr('checked',true);
var content=$('.content').val();
if(content.match(/src="[^"]+"/g)==null){
alert('文章内容没有图片');
return;
}else{
var strcount=content.match(/src="[^"]+"/g)[0].replace("src=\"","");
var val=strcount.substring(0,strcount.length-1).replace("http://cb2013.tdedu.org","");
$("#thumb_img").attr('src',val);
$("#img").val(val);
}
}
});

//取消缩略图
$('.qximg').click(function (){
$("#thumb_img").attr('src',"");
$("#img").val("");
});
