jquery 1.8正常但换1.9就不行了，哪里的问题？谢谢大家~

主要可能是这个引起的：

if(!$.browser.msie) return;

解决办法： 1. 下载官网的版本过渡文件：jquery-migrate-1.2.1 具体介绍看这儿. 2. 把下面的一段加到jquery的主文件中去：

(function() {

    var matched, browser;

    // Use of jQuery.browser is frowned upon.
    // More details: http://api.jquery.com/jQuery.browser
    // jQuery.uaMatch maintained for back-compat
    jQuery.uaMatch = function( ua ) {
        ua = ua.toLowerCase();

        var match = /(chrome)[ \/]([\w.]+)/.exec( ua ) ||
            /(webkit)[ \/]([\w.]+)/.exec( ua ) ||
            /(opera)(?:.*version|)[ \/]([\w.]+)/.exec( ua ) ||
            /(msie) ([\w.]+)/.exec( ua ) ||
            ua.indexOf("compatible") < 0 && /(mozilla)(?:.*? rv:([\w.]+)|)/.exec( ua ) ||
            [];

        return {
            browser: match[ 1 ] || "",
            version: match[ 2 ] || "0"
        };
    };

    matched = jQuery.uaMatch( navigator.userAgent );
    browser = {};

    if ( matched.browser ) {
        browser[ matched.browser ] = true;
        browser.version = matched.version;
    }

    // Chrome is Webkit, but Webkit is also Safari.
    if ( browser.chrome ) {
        browser.webkit = true;
    } else if ( browser.webkit ) {
        browser.safari = true;
    }

    jQuery.browser = browser;

    jQuery.sub = function() {
        function jQuerySub( selector, context ) {
            return new jQuerySub.fn.init( selector, context );
        }
        jQuery.extend( true, jQuerySub, this );
        jQuerySub.superclass = this;
        jQuerySub.fn = jQuerySub.prototype = this();
        jQuerySub.fn.constructor = jQuerySub;
        jQuerySub.sub = this.sub;
        jQuerySub.fn.init = function init( selector, context ) {
            if ( context && context instanceof jQuery && !(context instanceof jQuerySub) ) {
                context = jQuerySub( context );
            }

            return jQuery.fn.init.call( this, selector, context, rootjQuerySub );
        };
        jQuerySub.fn.init.prototype = jQuerySub.fn;
        var rootjQuerySub = jQuerySub(document);
        return jQuerySub;
    };

})();
