在网上找了一些关于判断是否为IE浏览器的方法，自己记录一遍以后查看：
方法一（IE6-8和IE11都适用）：
- function isIE() { //ie?
- if (!!window.ActiveXObject || "ActiveXObject" in window)
- { return true; }
- else
- { return false; }
- }
方法二：
//判断当前浏览类型
function
BrowserType()
{
var
userAgent = navigator.userAgent;
//取得浏览器的userAgent字符串
var
isOpera = userAgent.indexOf(
"Opera"
) > -1;
//判断是否Opera浏览器
var
isIE = userAgent.indexOf(
"compatible"
) > -1 && userAgent.indexOf(
"MSIE"
) > -1 && !isOpera;
//判断是否IE浏览器
var
isEdge = userAgent.indexOf(
"Windows NT 6.1; Trident/7.0;"
) > -1 && !isIE;
//判断是否IE的Edge浏览器
var
isFF = userAgent.indexOf(
"Firefox"
) > -1;
//判断是否Firefox浏览器
var
isSafari = userAgent.indexOf(
"Safari"
) > -1 && userAgent.indexOf(
"Chrome"
) == -1;
//判断是否Safari浏览器
var
isChrome = userAgent.indexOf(
"Chrome"
) > -1 && userAgent.indexOf(
"Safari"
) > -1;
//判断Chrome浏览器
if
(isIE)
{
var
reIE =
new
RegExp(
"MSIE (\\d+\\.\\d+);"
);
reIE.test(userAgent);
var
fIEVersion = parseFloat(RegExp[
"$1"
]);
if
(fIEVersion == 7)
{
return
"IE7"
;}
else
if
(fIEVersion == 8)
{
return
"IE8"
;}
else
if
(fIEVersion == 9)
{
return
"IE9"
;}
else
if
(fIEVersion == 10)
{
return
"IE10"
;}
else
if
(fIEVersion == 11)
{
return
"IE11"
;}
else
{
return
"0"
}
//IE版本过低
}
//isIE end
if
(isFF) {
return

//myBrowser() end
//判断是否是IE浏览器

var

(isIE)
{

"1"

else
{
return
"-1"

//判断是否是IE浏览器，包括Edge浏览器
function
IEVersion()

var
