您当前的位置: 有一些JS代码是从网上得到后进行处理的。
1、用SilverLight3时，有一次在启动页面(html页或aspx)为了对齐代码按一下Ctrl+K+D，运行后发现就SilverLight3主界面产生垂直滚动条，非常奇怪，不知什么原因。通过新建一个对比结果如下。（不是SilverLight4是否还会存在）
(1)原始代码(引用对象部份)：
- HTML code
<body>
<form id="form1" runat="server" style="height: 100%;">
<div id="silverlightControlHost">
<object data="data:application/x-silverlight-2," type="application/x-silverlight-2" width="100%" height="100%">
<param name="source" value="ClientBin/Temp.xap" />
<param name="onerror" value="onSilverlightError" />
<param name="background" value="white" />
<param name="minRuntimeVersion" value="3.0.40818.0" />
<param name="autoUpgrade" value="true" />
<a href="../Silverlight/Silverlight.exe" style="text-decoration: none;">
<img src="../Silverlight/Silverlight.jpg" alt="获取 Microsoft Silverlight插件" style="border-style: none" />
</a>
</object><iframe id="_sl_historyFrame" style='visibility: hidden; height: 0; width: 0; border: 0px'></iframe></div>
</form>
</body>
（2）对齐后的代码：
- HTML code
<body>
<form id="form1" runat="server" style="height: 100%;">
<div id="silverlightControlHost">
<object data="data:application/x-silverlight-2," type="application/x-silverlight-2"
width="100%" height="100%">
<param name="source" value="ClientBin/Temp.xap" />
<param name="onerror" value="onSilverlightError" />
<param name="background" value="white" />
<param name="minRuntimeVersion" value="3.0.40818.0" />
<param name="autoUpgrade" value="true" />
<a href="../Silverlight/Silverlight.exe" style="text-decoration: none;">
<img src="../Silverlight/Silverlight.jpg" alt="获取 Microsoft Silverlight插件" style="border-style: none" />
</a>
</object>
<iframe id="_sl_historyFrame" style='visibility: hidden; height: 0; width: 0; border: 0px'>
</iframe>
</div>
</form>
</body>
（3）代码内容没有任何变化，</div>却换行，却因为这样的换行导致产生垂直滚动条，大家可以试试。
2、有时我们希望关闭浏览器时进行用户注销(调用webService）。（在IE6、7、8、Mozilla Firefox、chrome测试没问题)
（1）、写一个JS文件并将该文件保存在Web根目录下.文件名为JsWebService.js)
- JScript code
function JsWebService() {
this.ServerURL = "../WebService/"; //服务器web路径
this.NameSpace = "http://A9.ERP/"; //Web命名空间
function createXMLHttpRequest() {
var xmlHttp;
if (window.ActiveXObject) {
xmlHttp = new ActiveXObject("Microsoft.XMLHTTP"); //IE
}
else if (window.XMLHttpRequest) { //非IE
xmlHttp = new XMLHttpRequest();
}
return xmlHttp;
}
//服务名、成员名、参数名集合、参数值集合、回调函数（若希望回调结果）
this.ServiceRequest = function(ServiceName, MethodName, ParamNames, ParamValues, CallBack) {
var xmlHttp = createXMLHttpRequest();
var SOAPString = GetSOAPHeader(this.NameSpace, MethodName, ParamNames, ParamValues);
var SOAPActionHeader = this.NameSpace + MethodName;
xmlHttp.open("POST", this.ServerURL + ServiceName, true);
if (CallBack != null) {
xmlHttp.onreadystatechange = function() {
if (xmlHttp.readyState == 4) {
if (xmlHttp.status == 200) {
CallBack(xmlHttp);
}
}
};
}
xmlHttp.setRequestHeader("Content-Type", "text/xml");
xmlHttp.setRequestHeader("SOAPAction", SOAPActionHeader);
xmlHttp.send(SOAPString);
}
function GetSOAPHeader(NameSpace, MethodName, ParamNames, ParamValues) {
var SOAPString = "";
SOAPString += "<soap:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\">\n"
SOAPString += "<soap:Body>\n";
SOAPString += "<" + MethodName + " xmlns=\"" + NameSpace + "\">\n";
if (ParamNames != null) {
for (var i = 0, j = ParamNames.length; i < j; i++) {
SOAPString += "<" + ParamNames[i] + ">" + ParamValues[i] + "</" + ParamNames[i] + ">\n";
}
}
SOAPString += "</" + MethodName + ">\n";
SOAPString += "</soap:Body>\n";
SOAPString += "</soap:Envelope>\n";
return SOAPString;
}
}
