将表单文本文件下载为XML文件。适用于IE10，但不适用于Chrome35或Firefox30

-1

试图创建一个按钮（或链接）从html表单textarea内下载数据并保存为XML文件。我可以解释为什么，但它会持续下去。将表单文本文件下载为XML文件。适用于IE10，但不适用于Chrome35或Firefox30

这里是我的工作（仅在IE10中）文本示例。我希望它能够在Chrome和Firefox中运行，但到目前为止还没有运气，有什么想法？

我并不需要什么特别的，只是扔在一个变量中的数据，把变到一个新文件，并提示另存为filename.xml中

<html> 

<head> 
<script lang="javascript"> 
function download(){ 
    var xmlContent = document.getElementById("Kitchen").innerHTML; //here we load our xml data 
    var blob = new Blob([xmlContent], { 
     type: "text/xml;charset=utf-8;" 
    }); 
    navigator.msSaveBlob(blob, "SaveAsYourFileNameHere.xml"); 
} 
</script> 
</head> 

<body style="background-color: rgb(225,225,225)"> 
<br> 
<form id="House"> 
    <textarea id="Kitchen"cols="20" rows="10">This is the Kitchen</textarea> 
</form> 
<br> 
<a href="#" onClick="download()">Download Xml</a><br> 
<br> 
</body> 

</html>

斑点只能在以IE FF和铬考虑数据的URI
