我正在寻找一个JavaScript库，只有AJAX没有其他功能。例如一个简单的小XMLHttp的包装。

I am searching for a Javascript Library Which has only AJAX no other feature. e.g. a Small Simple XMLHttp Wrapper.

推荐答案

这是不是一个库，但它是一个简单的小的XMLHTTP包装我做了：

This is not a library but it is a "Small Simple XMLHttp Wrapper" I made:

//params format:"bob=hi&id=1295&lol=haha"
function ajax_post(post_url,params,success_callback,fail_callback,timeout)
{
    var xmlHttp = new XMLHttpRequest();
    xmlHttp.open("POST",post_url, true);

    xmlHttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
    xmlHttp.setRequestHeader("Content-length", params.length);
    //xmlHttp.setRequestHeader("Connection", "close");

    xmlHttp.onreadystatechange=function()
    {
        if (xmlHttp.readyState == 4 ) 
        {
            clearTimeout(xmlHttpTimeout); 
            if(xmlHttp.status == 200)
            {
                success_callback();
            }
            else 
            {
                    fail_callback();
            }
        }
    }
    xmlHttp.send(params);

    var xmlHttpTimeout=setTimeout(ajaxTimeout,timeout);
    function ajaxTimeout()
    {
       xmlHttp.abort();
       fail_callback();
    }

}

function ajax_get(url,success_callback,fail_callback,timeout)
{
    var xmlHttp = new XMLHttpRequest();
    xmlHttp.open("GET",url, true);

    xmlHttp.onreadystatechange=function()
    {
        if (xmlHttp.readyState == 4 ) 
        {
            clearTimeout(xmlHttpTimeout); 
            if(xmlHttp.status == 200)
            {
                success_callback(xmlHttp.responseText);
            }
            else 
            {
                    fail_callback();
            }
        }
    }
    xmlHttp.send();

    var xmlHttpTimeout=setTimeout(ajaxTimeout,timeout);
    function ajaxTimeout()
    {
       xmlHttp.abort();
       fail_callback();
    }

}
