一、該功能只適用於須要頁面自動撐滿或縮小到可見區域,而且只對單個主體改變高度的需求。css
var ResetControl = function (pTask) { var _task = pTask || [], _isLock = false, bindEvent = function(){ var me = this; $(window).bind('resize.reset', function (event) { fire.call(me); if (_task.length === 0) { $(window).unbind('resize.reset', arguments.callee); } }); }, fire = function () { //當前頁面可見高度 var _iHeight = Math.min(window.innerHeight, document.documentElement.clientHeight), //頁面總體高度 _wHeight = Math.max(document.documentElement.clientHeight, document.documentElement.scrollHeight, document.body.clientHeight, document.body.scrollHeight), //頁面總體實際高度 _bHeight = document.body.offsetHeight, _resetHeight = 0; if (_iHeight > _bHeight) { //當前頁面可見高度 - 頁面總體實際高度 _resetHeight = _iHeight - _bHeight; } else { //當前頁面可見高度 - 頁面總體高度 _resetHeight = _iHeight - _wHeight; } for(var i = 0,l = _task.length;i < l;i++){ var _h = _task[i][0].offsetHeight; _h = (_h + _resetHeight) < 200 ? 200 : (_h + _resetHeight); _task[i].css("height", _h + "px"); } } this.push = function(pItem){ _task.push(pItem); } this.init = function(){ setTimeout(function () { fire(); bindEvent(); }, 100); } }
