高手帮我看看这个XML的作用 高分啊，解决了送分

var strXML= "<?xml version='1.0' encoding='UTF-8'?>" +
"<Query PID='" + <%= ProxyConstants.PID_CHOOSE_ARTICLE %> + "'>" +
"<PageIndex value='" + pageIndex + "'/>" +
"<QueryArticleType value='" + document.ShareDialog_choose_article.QueryArticleType.value + "'/>" +
"<ArticleNo value='" + document.ShareDialog_choose_article.ArticleNo.value + "'/>" +
"<CompanyNo value='0'/>"+// + window.opener.document.all("DesCompanyNo").value +
"<WarehouseNo value='0'/>"+//" + window.opener.document.all("DesWarehouseNo").value + "
"<ArticleCode value='" + replaceXmlParticularChar(document.ShareDialog_choose_article.ArticleCode.value) + "'/>"+
"<ArticleName value='"+ replaceXmlParticularChar(document.ShareDialog_choose_article.ArticleName.value) +"'/>"+
"<ArticleKind value='"+document.ShareDialog_choose_article.ArticleKind.value+"'/>"+
"<DealerArticleCode value='"+ replaceXmlParticularChar(document.ShareDialog_choose_article.DealerArticleCode.value) +"'/>"+
"<WorkArticleCode value='"+ replaceXmlParticularChar(document.ShareDialog_choose_article.WorkArticleCode.value) +"'/>"+
"<SupplyWarehouseCode value='"+ replaceXmlParticularChar(document.ShareDialog_choose_article.SupplyWarehouseCode.value) +"'/>"+
"</Query>";
var xmlDOM=new ActiveXObject("MSXML2.DOMDocument");
xmlDOM.async=false;
xmlDOM.loadXML(strXML);
这些干嘛用的？有什么作用啊？我看不懂，页面单击确定的时候就会执行这个javascript函数，完整的函数是这样子的
function ShareDialog_choose_article_onChange( kind ){
var pageIndex;
if( kind == 1 ) {
if(event.keyCode != 13) return;
pageIndex = 1;
document.ShareDialog_choose_article.QueryArticleType.value = 0;
}else if( kind == 2) {
pageIndex = parseInt(document.ShareDialog_choose_article.PageIndex.value) + 1;
}else if( kind == 3) {
pageIndex = parseInt(document.ShareDialog_choose_article.PageIndex.value) - 1;
if( pageIndex == 0 ) pageIndex = 1;
} else if( kind == 4 ) {
if( !checkHaveSelected() ) return;
pageIndex = 1;
document.ShareDialog_choose_article.QueryArticleType.value = 1;
} else {
pageIndex = 1;
document.ShareDialog_choose_article.QueryArticleType.value = 0;
}
//alert(window.opener.document.all("DesCompanyNo").value);
//alert(window.opener.document.all("DesWarehouseNo").value);
var strXML= "<?xml version='1.0' encoding='UTF-8'?>" +
"<Query PID='" + <%= ProxyConstants.PID_CHOOSE_ARTICLE %> + "'>" +

}望高手帮帮忙。郁闷 只有70分了，不好意思

沙发自己坐，页面点击确定，怎么就得到数据库里的信息了？

[chayahua767]

我看这好像是AJAX技术做的
var xmlDOM=new ActiveXObject("MSXML2.DOMDocument");//调用了一个类或者属性文件
xmlDOM.async=false;
xmlDOM.loadXML(strXML);//加载了上面定义的字符串，用XML的形式

你应该还有很多文件没有贴出来，很多东西看不到！

ajax呗

[yujinjin9]

这个用的是ajax技术ajax的好处就是不用刷新整个页面就可以调用后台，做到局部刷新，注意这段代码xmlHttp.open("POST","<%= urlHead + ConfigConstants.PROXY_SERVLET_URL %>",false)是中间的参数是要访问URL；xmlHttp.send(xmlDOM);发送解析的XML给后台；xmlResult=xmlHttp.responseXML;就是调用后台返回的内容然后用js解析。

估计有ajax调用的类来处理strXML的一串东西
