//document.domain = "cindasc.com";

/*
1.获取form中的元素对象
	IE:					document.formName.item("itemName")或document.formName.elements["elementName"];
	firefox:		document.formName.elements["elementName"]
	IE&firefox:	document.formName.elements["elementName"]

2.获取集合类中的对象
	IE:					array(i)或array[i]
	firefox:		array[i]
	IE&firefox:	array[i]

3.自定义属性
	IE:					obj.propertyname = value 或 obj.setAttribute ("propertyname", value)
	firefox:		obj.setAttribute ("propertyname", value);
	IE&firefox:	obj.setAttribute ("propertyname", value);

4.获取html元素
	IE:					通过id直接调用 或 document.getElementById ("id")
	firefox:		document.getElementById ("id");
	IE&firefox:	document.getElementById ("id");

5.javascript对象定义
	IE:					const or var
	firefox:		var
	IE&firefox:	var 并且不要定义与HTML元素相同的id

6. input.type属性问题
说明:IE下input.type属性为只读;但是Firefox下input.type属性为读写.

7. window.event问题

说明:window.event只能在IE下运行,而不能在Firefox下运行,这是因为Firefox的event只能在事件发生的现场使用. 
解决方法: 
IE: 
<input name="Button8_1" type="button" value="IE" onclick="javascript:gotoSubmit8_1()"/> 
... 
<script language="javascript"> 
function gotoSubmit8_1() { 
... 
alert(window.event); //use window.event 
... 
} 
</script> 
IE&Firefox: 
<input name="Button8_2" type="button" value="IE" onclick="javascript:gotoSubmit8_2(event)"/> 
... 
<script language="javascript"> 
function gotoSubmit8_2(evt) { 
... 
evt=evt?evt:(window.event?window.event:null);
alert(evt); //use evt
... 
} 
</script>

8. 获取页面地址
	IE&firefox:	window.location
	IE:					window.location或window.location.href
	firefox:		window.location

9. 模态和非模态窗口问题

说明:IE下,可以通过showModalDialog和showModelessDialog打开模态和非模态窗口;Firefox下则不能. 
解决方法:直接使用window.open(pageURL,name,parameters)方式打开新窗口。

如果需要将子窗口中的参数传递回父窗口,可以在子窗口中使用window.opener来访问父窗口. 例如：var parWin = window.opener; parWin.document.getElementById("Aqing").value = "Aqing"; 

10. body问题

Firefox的body在body标签没有被浏览器完全读入之前就存在；而IE的body则必须在body标签被浏览器完全读入之后才存在.
