我有一个数组,我希望在我的服务器上获得内容。我一直在浏览网页试图找到如何做到这一点,但没有成功。
假设我有一台服务器,我想在我的javascript中使用这个数组进入我服务器上的文件,我该怎么做?
我一直在浏览网页,寻找如何做到这一点,我想出了以下代码:
<html>
<!-- installs jquery and ajax. -->
<link href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.9/themes/base/jquery-ui.css" rel="stylesheet" type="text/css"/>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.5/jquery.min.js"></script>
<script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8/jquery-ui.min.js"></script>
<script>
var arr = ["one","two","three"];
arr = JSON.stringify(arr);
$.ajax({
url: "http://url_name_here.com",
type: "POST",
data: {
myArray : arr
}
});
alert('hello');
</script>
</html>

这是一个数组,没有必要对其进行字符串化,jQuery会将数据转换为有效的查询字符串
var arr=["one","two","three"];
$.ajax({
url: "/urltoMyOwnSite.php",
type: "POST",
data: {myArray : arr}
});
PHP(如果这就是你正在使用的那样)
$array = $_POST['myArray'];

fc.close();
//because its much easier than a flat file, we can write it back in the server response.
org.json.simple.JSONValue.writeJSONString(jsonObj, response.getWriter());
}
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException,

{
doGet(request, response);
}

jQuery会为你进行字符串化,所以你在你的例子中有效地对它进行了两次编码,这会导致你的问题。试试这个:
var arr = ["one","two","three"];
$.ajax({
url: "http://url_name_here.com",
type: "POST",
data: { myArray : arr }
});
