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.

稳了!魔兽国服回归的3条重磅消息!官宣时间再确认!
昨天有一位朋友在大神群里分享,自己亚服账号被封号之后居然弹出了国服的封号信息对话框。
这里面让他访问的是一个国服的战网网址,com.cn和后面的zh都非常明白地表明这就是国服战网。
而他在复制这个网址并且进行登录之后,确实是网易的网址,也就是我们熟悉的停服之后国服发布的暴雪游戏产品运营到期开放退款的说明。这是一件比较奇怪的事情,因为以前都没有出现这样的情况,现在突然提示跳转到国服战网的网址,是不是说明了简体中文客户端已经开始进行更新了呢?
