Question

这是我正在进行的项目的简化版本。

<!DOCTYPE html>
<html>
<body>

<script type="text/javascript">
    var bridge;

    if (window.XMLHttpRequest)
    {// code for IE7+, Firefox, Chrome, Opera, Safari
    xmlhttp=new XMLHttpRequest();
    }
    else
    {// code for IE6, IE5
    xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
    }

    xmlhttp.open("GET","MarketSpreadsheet.xml",false);
    xmlhttp.send();
    xmlDoc=xmlhttp.responseXML; 


    bridge = "xml data goes in here";

</script>


<svg height="300" width="300">
    <text id="thePopUp" x="150" y="150" font-size="30" fill="black" visibility="visible"></text>
</svg>

<script type="text/javascript">
thePopUp.textContent = bridge;
</script>

</body>
</html>

我正在尝试创建一个动态svg元素，由于某种原因，将xml字符串直接解析为thePopUp.textContent无法正常工作。我的计划是将xml数据转换为javascript变量矩阵，并使用它来分配文本内容。我的问题是xml.http.send（）; line使我的变量赋值无效，使输出“未定义”。我需要该行来访问我的xml文件，但该行阻止我将xml分配给变量（或者任何变量到该变量）。怎么回事？

AND JAVASCRIPT IS 
if (window.XMLHttpRequest){
        xmlhttp=new XMLHttpRequest();
    }
    else {// code for IE6, IE5
        xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
    }
    xmlhttp.open("GET","xml/fill_in_the_blank.xml",false);
    xmlhttp.send();
    xmlDoc=xmlhttp.responseXML;


    myXMLDoc=xmlDoc.getElementsByTagName('item');
    totalQuestion = myXMLDoc.length;

$（ “＃thePopUp”）。文本（totalQuestion）

但是你需要使用“JQUERY”和“网络服务器或像手术一样”

XML干扰javascript变量
