我正在尝试访问另一个域中的Web服务，但它不返回任何内容。后来我发现这是一个跨域访问的问题。

我在网上搜索了很多文章，但像我这样的新手都看不懂。:(

有人可以帮助我如何访问Web服务吗？

以下是我的代码。

//variables for Add Contacts
var addAccountServiceUrl = 'http://crm.eyepax.net/organization.asmx?op=WriteOrg'; // Preferably write this out from server side
var OrganizationID=123;
var ParentID=123    ;
var AccountManagerID="123";
var OrganizationName="Testapple";
var IncorporationNo="23";
var PostAddress="asdfklj asldfj";

var sErr;

function addContact()
{
//this is to be commented soon! 
alert("function called");
//update the webservice soapmesg
