<html>
<head>
<script type="text/javascript" src="jquery-1.7.2.js"></script>
<script type="text/javascript">
$(document).ready(function(){
$.ajax({
        type: "POST", 
        url: "Service1.asmx/HelloWorld", 
        data: "{}",
        contentType: "application/json; charset=utf-8",
        dataType: "json",
        success: function(msg) {
            alert("Result: " + msg);
        },
        error: function(XMLHttpRequest, textStatus, errorThrown) {
            alert("Error: " + textStatus);
    }
});
});
</script>
</head>

When i run index.html in browser i get the Error alert.. Tried alot of things, but cant find out whats missing.. 当我在浏览器中运行index.html时，我收到错误警报。尝试了很多事情，但找不到丢失的内容。

Answer 1

your json in encapsulated in a xml string, i guess thats your problem. 您的json封装在xml字符串中，我想这就是您的问题。
