在实际开发中会遇到确实需要获取隐藏元素的宽高,这儿所说的隐藏元素是display为none的元素。
可使用jQuery Actual Plugin插件来完成,其源码如下:
;( function ( $ ){ $.fn.addBack = $.fn.addBack || $.fn.andSelf; $.fn.extend({ actual : function ( method, options ){ // check if the jQuery method exist if( !this[ method ]){ throw '$.actual => The jQuery method "' + method + '" you called does not exist'; } var defaults = { absolute : false, clone : false, includeMargin : false, display : 'block' }; var configs = $.extend( defaults, options ); var $target = this.eq( 0 ); var fix, restore; if( configs.clone === true ){ fix = function (){ var style = 'position: absolute !important; top: -1000 !important; '; // this is useful with css3pie $target = $target. clone(). attr( 'style', style ). appendTo( 'body' ); }; restore = function (){ // remove DOM element after getting the width $target.remove(); }; }else{ var tmp = []; var style = ''; var $hidden; fix = function (){ // get all hidden parents $hidden = $target.parents().addBack().filter( ':hidden' ); style += 'visibility: hidden !important; display: ' + configs.display + ' !important; '; if( configs.absolute === true ) style += 'position: absolute !important; '; // save the origin style props // set the hidden el css to be got the actual value later $hidden.each( function (){ // Save original style. If no style was set, attr() returns undefined var $this = $( this ); var thisStyle = $this.attr( 'style' ); tmp.push( thisStyle ); // Retain as much of the original style as possible, if there is one $this.attr( 'style', thisStyle "htmlcode">;( function ( factory ) { if ( typeof define === 'function' && define.amd ) { // AMD. Register module depending on jQuery using requirejs define. define( ['jquery'], factory ); } else { // No AMD. factory( jQuery ); } }( function ( $ ){ $.fn.addBack = $.fn.addBack || $.fn.andSelf; $.fn.extend({ actual : function ( method, options ){ // check if the jQuery method exist if( !this[ method ]){ throw '$.actual => The jQuery method "' + method + '" you called does not exist'; } var defaults = { absolute : false, clone : false, includeMargin : false, display : 'block' }; var configs = $.extend( defaults, options ); var $target = this.eq( 0 ); var fix, restore; if( configs.clone === true ){ fix = function (){ var style = 'position: absolute !important; top: -1000 !important; '; // this is useful with css3pie $target = $target. clone(). attr( 'style', style ). appendTo( 'body' ); }; restore = function (){ // remove DOM element after getting the width $target.remove(); }; }else{ var tmp = []; var style = ''; var $hidden; fix = function (){ // get all hidden parents $hidden = $target.parents().addBack().filter( ':hidden' ); style += 'visibility: hidden !important; display: ' + configs.display + ' !important; '; if( configs.absolute === true ) style += 'position: absolute !important; '; // save the origin style props // set the hidden el css to be got the actual value later $hidden.each( function (){ // Save original style.
