写入服务器上的文件的JavaScript输出 [英] Write javascript output to file on server
问题描述
所以，我有一个测试用户的屏幕分辨率这个HTML文件，然后使用Javascript安装的插件。因此，当用户访问该页面就看到：（EG）您当前的屏幕分辨率为1024x768，并且您已经安装了以下插件：插件No.2- Java部署工具包7.0.10.8 [地点：npdeployJava1.dll]，插头 - 在No.3-的Java（TM）平台SE 7 U1 [地址：npjp2.dll]，插件No.4-的Microsoft Office 2003【地点：NPOFFICE.DLL] ...我还需要保存的信息文件在服务器上。所有的用户在Firefox或Chrome。如何做到这一点使用AJAX？
So I have this HTML file that tests the user's screen resolution, and plugins installed using Javascript. So when the user accesses the page it sees: (e.g.) Your current screen resolution is 1024x768 and you have the following plugins installed: Plug-in No.2- Java Deployment Toolkit 7.0.10.8 [Location: npdeployJava1.dll], Plug-in No.3- Java(TM) Platform SE 7 U1 [Location: npjp2.dll], Plug-in No.4- Microsoft Office 2003 [Location: NPOFFICE.DLL]... I also need to save this information in a file on the server. All users are having firefox or chrome. How do I do this using AJAX?
<html>
<body>
<script language="JavaScript1.2">
document.write("Your current resolution is "+screen.width+"*"+screen.height+"")
</script>
<BR><BR>
<SCRIPT LANGUAGE="JavaScript">
var num_of_plugins = navigator.plugins.length;
for (var i=0; i < num_of_plugins; i++) {
var list_number=i+1;
document.write("<font color=red>Plug-in No." + list_number + "- </font>"+navigator.plugins[i].name+" <br>[Location: " + navigator.plugins[i].filename + "]<p>");
}
</script>
</body>
</html>
感谢
推荐答案
如果没有的jQuery（原始的JavaScript）：
Without jQuery (raw JavaScript):
var data = "...";// this is your data that you want to pass to the server (could be json)
//next you would initiate a XMLHTTPRequest as following (could be more advanced):
var url = "get_data.php";//your url to the server side file that will receive the data.
var http = new XMLHttpRequest();
http.open("POST", url, true);
//Send the proper header information along with the request
http.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
http.setRequestHeader("Content-length", params.length);
http.setRequestHeader("Connection", "close");
http.onreadystatechange = function() {//Call a function when the state changes.
if(http.readyState == 4 && http.status == 200) {
alert(http.responseText);//check if the data was received successfully.
}
}
http.send(data);
使用 jQuery的：
$.ajax({
type: 'POST',
url: url,//url of receiver file on server
data: data, //your data
success: success, //callback when ajax request finishes
dataType: dataType //text/json...
});
我希望这有助于：）
I hope this helps :)
