解释上面代码段:
1、$("#warn").slideUp("slow");向上滑动, $("#warn").slideDown(2000);向下滑动
2、$.post(window.location.href,{op : 'setwarn'},function(data)
{
return true;
})
运用到了ajax 提交 跟服务器进行交互,
第一个参数是请求的地址 第二个是提交的参数 第三个是请求成功 之后调用的方法
参数op 的值是setwarn json串的格式具体运用解说看http://www.w3school.com.cn/jquery/ajax_post.asp
url 对应 locaotion.href(取得是当前页面的地址)
data对应 {op:setwarn} 字符串
success 对应 函数
3、window.onload = function(){}作用一般在<text/javascript>中写的函数都要在body页面中调用,用此函数就不用等着body页面中调用就可以执行了
