本文实例讲述了jQuery判断浏览器并动态调整select宽度的方法。分享给大家供大家参考，具体如下：
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>Untitled Page</title> <mce:script src="jquery-1.4.4.js" mce_src="jquery-1.4.4.js" type="text/javascript"></mce:script> <mce:script type="text/javascript"><!-- function userBrowser() { var browserName = navigator.userAgent.toLowerCase(); if (/msie/i.test(browserName) && !/opera/.test(browserName)) { browserName="ie"; } else if (/firefox/i.test(browserName)) { browserName = "firefox"; } else if (/chrome/i.test(browserName) && /webkit/i.test(browserName) && /mozilla/i.test(browserName)) { browserName = "chrome"; } else if (/opera/i.test(browserName)) { browserName = "opera"; } else if (/webkit/i.test(browserName) && !(/chrome/i.test(browserName) && /webkit/i.test(browserName) && /mozilla/i.test(browserName))) { browserName = "safari"; } else { browserName = "unknow"; } return browserName; } $(function() { var browser = userBrowser(); if (browser == "ie") { $("select").each(function() { $(this).css("width", ($(this).width() + 10) + "px"); }); } else if (browser == "firefox") { $("select").each(function() { $(this).css("width", ($(this).width() + 8) + "px"); }); } else if (browser == "chrome") { $("select").each(function() { $(this).css("width", ($(this).width() + 6) + "px"); }); } else if (browser == "safari") { $("select").each(function() { $(this).css("width", ($(this).width() + 30) + "px"); }); } }); // --></mce:script> </head> <body> <div> <> <input id="t1" type="text" /><br /> <select id="s1"> <option>1</option> </select><br /> <textarea id="TextArea1" cols="20" rows="2"> </div> </body> </html>
希望本文所述对大家jQuery程序设计有所帮助。
