带set参数的jQuery外径?

带set参数的jQuery外径?,jquery,Jquery,因为我也面临着不正确的宽度- 我看到了这段代码: _resizeMenu: function() { var ul = this.menu.element; ul.outerWidth( Math.max( //<------ ul.width( "" ).outerWidth(), this.element.outerWidth() ) ); } \u resizeMenu:function(){ var ul=this.m

因为我也面临着不正确的宽度-

我看到了这段代码:

_resizeMenu: function() {
    var ul = this.menu.element;
    ul.outerWidth( Math.max(    //<------
        ul.width( "" ).outerWidth(),
        this.element.outerWidth()
    ) );
}
\u resizeMenu:function(){
var ul=this.menu.element;

ul.outerWidth(Math.max(//参见jQuery的来源:

// Create innerHeight, innerWidth, height, width, outerHeight and outerWidth methods
jQuery.each( { Height: "height", Width: "width" }, function( name, type ) {
    jQuery.each( { padding: "inner" + name, content: type, "": "outer" + name }, function( defaultExtra, funcName ) {
        // margin is only for outerHeight, outerWidth
        jQuery.fn[ funcName ] = function( margin, value ) {
            var chainable = arguments.length && ( defaultExtra || typeof margin !== "boolean" ),
                extra = defaultExtra || ( margin === true || value === true ? "margin" : "border" );

            return jQuery.access( this, function( elem, type, value ) {
                var doc;

                if ( jQuery.isWindow( elem ) ) {
                    // As of 5/8/2012 this will yield incorrect results for Mobile Safari, but there
                    // isn't a whole lot we can do. See pull request at this URL for discussion:
                    // https://github.com/jquery/jquery/pull/764
                    return elem.document.documentElement[ "client" + name ];
                }

                // Get document width or height
                if ( elem.nodeType === 9 ) {
                    doc = elem.documentElement;

                    // Either scroll[Width/Height] or offset[Width/Height] or client[Width/Height], whichever is greatest
                    // unfortunately, this causes bug #3838 in IE6/8 only, but there is currently no good, small way to fix it.
                    return Math.max(
                        elem.body[ "scroll" + name ], doc[ "scroll" + name ],
                        elem.body[ "offset" + name ], doc[ "offset" + name ],
                        doc[ "client" + name ]
                    );
                }

                return value === undefined ?
                    // Get width or height on the element, requesting but not forcing parseFloat
                    jQuery.css( elem, type, extra ) :

                    // Set width or height on the element
                    jQuery.style( elem, type, value, extra );
            }, type, chainable ? margin : undefined, chainable, null );
        };
    });
});
如您所见,innerHeight、innerWidth、height、width、outerHeight和outerWidth都是使用参数
margin
value
创建的

由于第一个参数不是布尔值(
typeof margin!=“boolean”
),因此
chaineable
将为true,这反过来意味着在调用
jQuery.acess
chaineable?margin:undefined
)时,margin参数将用作值

这意味着它将调用
jQuery.style(elem,type,value,extra)
其中
type
是“宽度”;
value
Math的结果。max
extra
将是“边框”


通过调试
jquery-1.10.2.js#9746
@

你是说有一个未记录的重载吗?是的,似乎是这样。
jquery.style
似乎也没有记录。顺便说一句,使用参数调用
width
的唯一区别似乎是
extra
设置为“内容”。
