Question

我是AJAX世界的新手，所以请原谅我的n00bishness。我有一个XML文档，如下所示：

<juices>
<smoothie id="SY4301">
    <name>Strawberry Yumghurt</name>
    <price currency="GBP">

        <perunit type="RRP">1.89</perunit>
        <percrate>28.50</percrate>
    </price>
    <description>Velvety yoghurt smoothie made with fresh strawberry and rasperries.</description>

</smoothie>
</juices>

我有一个XSL文档正在加载除页面加载之外的所有内容，但我想要实现的是点击（链接或按钮，我不介意哪个），替换其中一个div的内容（#description），其中包含其图像的成分列表，其位置存储在图像属性中。

我已经看了一些教程，建议使用jQuery来实现这一点，但我没有太多运气让它工作。我知道我也可以在JS中使用XMLHttpRequest函数，但不确定哪种方法更好。

非常感谢任何建议！

谢谢，安迪

首先你需要了解你在使用ajax做什么，因为有不同的方法来使用jquery调用ajax，让我们使用基本属性

//Handle the ajax in the event click of your button with ID MyButton
$('#MyButton').click(function(){
    $.ajax({
       type: "Type of your http Request could be GEt or Post",
       url: " the url where you obtain that xml",
       data: "ïf you need to pass some data to the url"
       dataType: "in your case should be XML which is the data type that you're going to handle in the success function",
       success: function(data){ 
            //parse your xml which it contains in the var data
            //You could set the data parse in your div with a append or html method
       }'define a function or put a function already defined',
       error: 'define a function in case of error'
    });
});
