首先调用get_content()方法，然后在get_content方法中调用handle_content()方法，然后在handle_content方法中调用post_content()方法，最后在post_content方法中再调用get_content()方法，不知到该怎样避免超出内存呢？

function get_content()
{
    $.ajax({
        url:'/air_ajax.php',

        dataType:'json',

        async:false,
        success:function(json)
        {
            if(json.status)
            {
                handle_content(json.article);
            }
            else
            {
                console.log('get article none');
            }
        }
    });
}

function handle_content(article)
{
    if(!article){
        console.log('article is illegal');
        console.log(article);
        return;
    }
    var $box=$('<p class="wrap">'+article.content+'</p>');
    var $children=$box.find('#content').children();
    if($children.length>0)
    {
        $children.each(function()
        {
            //console.log('hello');
            var tag=this.nodeName.toLowerCase();

             if(this.nodeType==1 && tag!=='p' && tag!=='p')
             {
             var html=$(this).html();
             //console.log(this);
             $(this).replaceWith('<p>'+html+'</p>');
             }

        });
    }

    $html.find('a').remove();

    data={id:article.id,content:html};
    
    post_content(data);
}
**var count;**
