编程经验：JS获取当前浏览器版本

提示：您可以先修改部分代码再运行

<html> <head> <title>JS完整获取IE浏览器信息</title> </head> <body leftmargin="0" topmargin="0" marginwidth="0" marginheight="0"> <table width="435" border="1" cellspacing="3" cellpadding="0"> <tr> <td>浏览器类型</td> <td> <script>document.write(navigator.appName)</script> </td> </tr> <tr> <td >浏览器版本</td> <td > <script>document.write(navigator.appVersion)</script> </td> </tr> <tr> <td>浏览器语言</td> <td> <script>document.write(navigator.browserLanguage)</script> </td> </tr> <tr> <td >CPU类型</td> <td > <script>document.write(navigator.cpuClass)</script> </td> </tr> <tr> <td>操作系统</td> <td> <script>document.write(navigator.platform)</script> </td> </tr> <tr> <td >系统语言</td> <td > <script>document.write(navigator.systemLanguage)</script> </td> </tr> <tr> <td>用户语言;</td> <td> <script>document.write(navigator.userLanguage)</script> </td> </tr> <tr> <td >在线情况</td> <td > <script>document.write(navigator.onLine)</script> </td> </tr> <tr> <td>屏幕分辨率</td> <td> <script>document.write(window.screen.width+"x"+window.screen.height)</script></td> </tr> <tr> <td>颜色</td> <td> <script>document.write(window.screen.colorDepth+"位")</script></td> </tr> <tr> <td>字体平滑</td> <td><script>document.write(window.screen.fontSmoothingEnabled)</script></td> </tr> <tr> <td>appMinorVersion</td> <td> <script>document.write(navigator.appMinorVersion)</script> </td> </tr> <tr> <td >appCodeName</td> <td > <script>document.write(navigator.appCodeName)</script> </td> </tr> <tr> <td>cookieEnabled</td> <td> <script>document.write(navigator.cookieEnabled)</script> </td> </tr> <tr> <td >userAgent</td> <td > <script>document.write(navigator.userAgent)</script> </td> </tr> <tr> <td>javaEnabled</td> <td> <script>document.write(navigator.javaEnabled())</script> </td> </tr> <tr> <td >taintEnabled</td> <td > <script>document.write(navigator.taintEnabled())</script> </td> </tr> <tr> <td>connectionType</td> <td> <script>document.write(oClientCaps.connectionType)</script> </td> </tr> </table> </body> </html>

浏览器版本

4.0 (compatible; MSIE 7.0; Windows NT 5.1; .NET CLR 2.0.50727; .NET CLR 3.0.04506.30; .NET CLR 3.0.04506.648; .NET CLR 3.5.21022; .NET CLR 3.0.4506.2152; .NET CLR 3.5.30729; InfoPath.2)

a=navigator.appVersion.split(";") //以";"号分割上面的字符串

a {...} Object

[0] "4.0 (compatible" String

[1] " MSIE 7.0" String

[2] " Windows NT 5.1" String

[3] " .NET CLR 2.0.50727" String

[4] " .NET CLR 3.0.04506.30" String

[5] " .NET CLR 3.0.04506.648" String

[6] " .NET CLR 3.5.21022" String

[7] " .NET CLR 3.0.4506.2152" String

[8] " .NET CLR 3.5.30729" String

[9] " InfoPath.2)" String

b=a[1].split(" ")//分割a[1]数组第二字符串

b {...} Object

[0] "" String

[1] "MSIE" String

[2] "7.0" String

return b[2] // 返回IE 版本号"7.0"

关于IE打印的问题，由于IE6不支持全屏打印，如果你的窗口时满屏，会打印不全。IE7和IE8都支持全屏打印，所以针对IE打印我们要分开处理。

if (document.getElementById('PrintA4')) {

if (isIE() == 6.0) {

document.getElementById('PrintA4').src = document.URL + "&PageSize=A4" + "&IEType=6.0";

}

else {

document.getElementById('PrintA4').src = document.URL + "&PageSize=A4" + "&IEType=7.0";

}

document.getElementById('PrintA3').src = document.URL + "&PageSize=A3";

}

</script>

我们后台根据获取到的pUrl，在后台再次分割字符串，对IE6和Ie7进行处理就行了。

string pUrl = Request.RawUrl;//获取传来的参数

var rng = document.body.createTextRange();

rng.moveToElementText(obj);

rng.scrollIntoView();

rng.select();

rng.execCommand("Copy");

rng.collapse(false);

}

function runCode(obj) {

var winname = window.open('', "_blank", '');

winname.document.open('text/html', 'replace');

winname.document.writeln(obj.value);

winname.document.close();

}

function saveCode(obj) {

var winname = window.open('', '_blank', 'top=10000');

winname.document.open('text/html', 'replace');

winname.document.writeln(obj.value);

winname.document.execCommand('saveas','','code.htm');

winname.close();

}
</script>
