phpnew blog内置discuz ubb类型的编辑器, 编辑器功能上有在光标处插入, 可在ie11上一直不准确.

今天分析一下, 终于找到原因. 旧版本的js文件写的浏览器判断有异常, 所以导致插入点一直在头部. 今天修复之.

提供一个js函数. 返回一个数组.

复制代码 代码如下:

function sys_userAgent(){

var userAgent = navigator.userAgent,

rMsie = /(msies|trident.*rv:)([w.]+)/,

rFirefox = /(firefox)/([w.]+)/,

rOpera = /(opera).+version/([w.]+)/,

rChrome = /(chrome)/([w.]+)/,

rSafari = /version/([w.]+).*(safari)/;

var browser,version,ua;

ua = userAgent.toLowerCase();

var match = rMsie.exec(ua);

if (match != null) {

return { browser : "ie", version : match[2] || "0" };

}

if (!!window.ActiveXObject || "ActiveXObject" in window){

return { browser : "ie", version : "0"};

}

var match = rFirefox.exec(ua);

if (match != null) {

return { browser : "firefox", version : match[2] || "0" };

}

var match = rOpera.exec(ua);

if (match != null) {

return { browser : "opera", version : match[2] || "0" };

}

var match = rChrome.exec(ua);

if (match != null) {

return { browser : "chrome", version : match[2] || "0" };

}

var match = rSafari.exec(ua);

if (match != null) {

return { browser : "safari", version : match[1] || "0" };

}

if (match != null) {

return { browser : "", version : "0" };

}

}

希望对大家有帮助.
