javascript结合ajax读取txt文件内容
代码很简洁,这里就不多废话了,直接上源码
html代码
<!doctypehtml> <html> <head> <metacharset="utf-8"/> </head> <body> <buttontype="button" onclick="show()">请求数据</button> <scriptsrc="ajax.js"></script> <script> functionshow(){ Ajax('read.txt?datetime=newDate.getTime',function(str){alert(str);},function(){alert('失败了');}) }; </script> </body> </html>
javascript代码
functionAjax(url,fnSucc,fnFaild) { //1.创建ajax对象 if(window.XMLHttpRequest) {//codeforIE7+,Firefox,Chrome,Opera,Safari varoAjax=newXMLHttpRequest(); } else {//codeforIE6,IE5 varoAjax=newActiveXObject("Microsoft.XMLHTTP"); } //2.链接服务器(打开服务器的连接) //open(方法,文件名,异步传输) oAjax.open('GET',url,true); //3.发送 oAjax.send(); //4.接收返回 oAjax.onreadystatechange=function() { if(oAjax.readyState==4) { if(oAjax.status==200) { fnSucc(oAjax.responseText); } else { fnFaild(oAjax.status); } }; }; }
请求的文件为read.txt
内容随便填写
