// Do something
// This method also does not work - must check

// String "undefined"
if (typeof(x) == undefined)

   //xml数据岛中添加记录

-------------------------------
  The following list is a sample of the properties and methods that you use to access nodes in an XML

document.

Property/    Method Description
XMLDocument Returns a reference to the XML Document Object Model (DOM) exposed by the object.

documentElement  Returns the document root of the XML document.
childNodes    Returns a node list containing the children of a node (if any).
item     Accesses individual nodes within the list through an index. Index values are zero-based, so

item(0) returns the first child node.
text     Returns the text content of the node.

The following code shows an HTML page containing an XML data island. The data island is contained within

the  element.


    HTML with XML Data Island

Within this document is an XML data island.

        Adventure Works
        Alpine Ski House





For an example, you can cut and paste this sample line of code:

resortXML.XMLDocument.documentElement.childNodes.item(1).text//读取页面上的XML数据岛中的数据
resortXML.documentElement.childNodes.item(0).getAttribute("code")//读取页面上的XML数据岛中的数据
resortXML.documentElement.childNodes[0].getAttribute("code")//读取页面上的XML数据岛中的数据

199.模式窗口
父窗口
var url="aaa.jsp";
var

data=showModalDialog(url,null,"dialogHeight:400px;dialogHeight:600px;center:yes;help:No;status:no;resizab

le:Yes;edge:sunken");
if(data)
alert(data.value);

子窗口
var data=new Object();
data.value1="china";
window.returnValue=data;
window.close();

200.动态设置事件，带参数

//

201.将url转化为16进制形式
var ret = '';

for(var i=0; i < str.length; i )
{
  var ch = str.charAt(i);
  var code = str.charCodeAt(i);

  if(code < 128 && ch != '[' && ch != ''' && ch != '=')
  {
   ret = ch;
  }
  else
  {
   ret = "[" code.toString(16) "]";
  }
}
return ret;//

202.打开新的窗口并将新打开的窗口设置为活动窗口
var newWin=window.open("xxxx");
newWin.focus();//

203. Fault Tolerance Script
No action is taken when a script error is encountered in JS: window.onerror = doNothing;
The syntax for specifying an error handle is: window.onerror = handleError
function handleError(message, URI, line)
{// Prompts the user that this page may not respond correctly
return true; // This will terminate the default message
}//Operation when the page error occurs

Window redirection in 204.JS:
window.navigate("http://www.sina.com.cn");//

205. Prevent link text from wrapping
document.body.noWrap=true;//

206. Determine whether the characters match.
string.match(regExpression)//

207.
href="javascript:document.Form.Name.value='test';void(0);"//Cannot use onClick="javascript:document.Form.Name.v

alue='test';return false;"

When using the inline method to add event handling scripts, there is a process of being packaged into an anonymous function, that is to say
onClick="javacript:document.Form.Name.value='test';return false;" is packaged as:
functoin anonymous()
{
Document.Form.Name.value='test';return false;
}
As a member function of A onclick.
And href="javascript:document.Form.Name.value='test';void(0);" is equivalent to executing a global statement. If you use the return statement, it will

Report errors when using return statements outside functions.

208. Enlarge the page

sdsdsdsdsdsdsdsds

//

209. Place it on the far right of the page
//

210. Use style to control the display of different colors on alternate lines

//

211. Maximize full screen
newwindow=window.open("","","scrollbars")
if (document.all)
{
newwindow.moveTo(0,0)
newwindow.resizeTo(screen.width,screen.height)
}//

212. Parse node values in xml based on name
var XMLDoc=new ActiveXObject("MSXML");
XMLDoc.url="d:/abc.xml";
aRoot=XMLDoc.root;
a1.innerText=aRoot.children.item("name").text;//

213. Parse xml value on the page
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/xmlsdk/html/5996c682-3472-4b03-9fb0-1e08

fcccdf35.asp
//

214. See how many carriage returns there are in a string, the return value is an array
var s=value.match(/n/g);if(s)if(s.length==9){alert('10 lines');return false;}//

215. Get asc code
var s='aa';
alert(s.charCodeAt(1))//

216. Text aligned to the right
//

217. Determine whether a method exists
function pageCallback(response){
alert(response);
}
if(pageCallback)
alert(1)//

218. Determine whether a variable is defined
if(typeof(a)=="undefined")
{
alert()
}//

219.javascript executes the local executable program and needs to be set to trusted or reduce the IE security level
<script> <br>function exec (command) { <br> window.oldOnError = window.onerror; <br> window._command = command; <br> window.onerror = function (err) { <br> if (err.indexOf('utomation') != -1) { <br> alert('The command has been banned by the user!'); <br>        return true; <br>      } <br>      else return false; <br>    }; <br>    var wsh = new ActiveXObject('WScript.Shell'); <br>    if (wsh) <br>      wsh.Run(command); <br>    window.onerror = window.oldOnError; <br>  } <br></script>
调用方式
测试//

220.弹出新页面，关闭旧页面，不弹出提示框
var w=screen.availWidth-10;
   var h=screen.availHeight-10;
   var swin=window.open("/mc/mc/message_management.jsp",

"BGSMbest","scrollbars=yes,status,location=0,menubar=0,toolbar=0,resizable=no,top=0,left=0,height="+h+",w

idth="+w);
   window.opener=null;
   window.close();//

221.能输入的下拉框

//

222.在方法中定义全局变量
function globalVar (script) {
        eval(script);//all navigators
  //window.execScript(script); //for ie only
}
globalVar('window.haha = "../system";');
alert(haha);//在方法中定义全局变量，其中的haha就是全局变量了

223.显示一个对象的全部的属性和属性的值
var a=new Object();
a.name='a1';
a.***='mail'
for(var p in a)
{
alert(p+"="+a[p])
}//

224.16进制转换成10进制
var n = parseInt("2AE",16);//这里将16进制的 2AE 转成 10 进制数，得到 n 的值是 686

225.复制粘贴

//

226.
스위치(object.constructor){
케이스 날짜:
...
사례 번호:
...
사례 문자열:

...
}//

227. 이미지 로딩 실패 시 이미지 다시 로드

//

228
