带set参数的jQuery外径?
因为我也面临着不正确的宽度- 我看到了这段代码: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
_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
和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
是Math的结果。max
和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”。
