主要是分为两大类：IE、其它浏览器
IE8以下只支持这种
InputVoltage.innerText = xmlDoc.getElementsByTagName(id)[0].text,
其它浏览器大部分兼容这种
InputVoltage.innerHTML =xmlDoc.getElementsByTagName(id)[0].textContent。
部分代码如下：
function Gett(str)
{ // 判断MyBrowserType，以决定读取text还textcontent。
var browsertype= checkBrowser();
var url="curr_run_xml.php";
// code for IE7+, Firefox, Chrome, Opera, Safari
try{ xmlHttp=new XMLHttpRequest();
xmlHttp.onreadystatechange=function()
{
if (xmlHttp.readyState==4 && xmlHttp.status==200)
{ xmlDoc=xmlHttp.responseXML;
InputVoltage.innerHTML = GetXmlTextByTagName(xmlDoc,"input_vol_a")
OutputVoltage.innerHTML = GetXmlTextByTagName(xmlDoc,"output_vol_a");
OutputMinVoltage.innerHTML = GetXmlTextByTagName(xmlDoc, "output_min_vol");
OutputMaxVoltage.innerHTML = GetXmlTextByTagName(xmlDoc, "output_max_vol");
Frequency.innerHTML = GetXmlTextByTagName(xmlDoc, "input_fre");
CurrentLoad.innerHTML = GetXmlTextByTagName(xmlDoc, "output_load_a"); <?php if(isset($rs))
{
foreach ($rs as $key => $value)
{
