Discuz7.2 IE9兼容性写法 杜工完全修补方案

现象： 1. IE9快速发帖不跳转 2. IE9管理员处理帖子失败 3. IE9登录不跳转，需要手动刷新 原因： 1. AJAXPOST函数判断out了 2. 动态创建iframe时各浏览器处理方式不同 解决方法： 1. 修改templates/header.htm 把 meta http-equiv=x-ua-compatible content=ie=7 / 替换为 复制代码代码如下: ![if lte IE 8] meta http-equiv=x-ua-compatible content=ie=7 / ![endif] ![if IE 9] meta http-equiv=x-ua-compatible content=ie=9 / ![endif] 2.修改include/js/common.js 把ajaxpost函数替换为： 复制代码代码如下: function ajaxpost(formid, showid, waitid, showidclass, submitbtn, recall) { var waitid = typeof waitid == ’undefined’ || waitid === null ? showid : (waitid !== ’’ ? waitid : ’’); var showidclass = !showidclass ? ’’ : showidclass; var ajaxframeid = ’ajaxframe’; var ajaxframe = $(ajaxframeid); var formtarget = $(formid).target; var handleResult = function() { var s = ’’; var evaled = false; showloading(’none’); try { s = $(ajaxframeid).contentWindow.document.XMLDocument.text; } catch(e) { try { s = $(ajaxframeid).contentWindow.document.documentElement.firstChild.wholeText; } catch(e) { try { s = $(ajaxframeid).contentWindow.document.documentElement.firstChild.nodeValue; } catch(e) { s = ’内部错误，无法显示此内容’; } } } if(s != ’’ s.indexOf(’ajaxerror’) != -1) { evalscript(s); evaled = true; } if(showidclass) { $(showid).className = showidclass; if(submitbtn) { submitbtn.disabled = false; } } if(!evaled (typeof ajaxerror == ’undefined’ || !ajaxerror)) { ajaxinnerhtml($(showid), s); } ajaxerror = null; if($(formid)) $(formid).target = formtarget; if(typeof recall == ’function’) { recall(); } else { eval(recall); } if(!evaled) evalscript(s); ajaxframe.loading = 0; $(’append_parent’).removeChild(ajaxframe); }; if(!ajaxframe) { try{ ajaxframe = document.createElement(’iframe name='’ + ajaxframeid + ’' /iframe’); }catch(e){ ajaxframe = document.createElement(’iframe’); ajaxframe.name = ajaxframeid; ajaxframe.id = ajaxframeid; } ajaxframe.style.display = ’none’; ajaxframe.loading = 1; $(’append_parent’).appendChild(ajaxframe); } else if(ajaxframe.loading) { return false; } _attachEvent(ajaxframe, ’load’, handleResult); showloading(); $(formid).target = ajaxframeid; $(formid).action += ’inajax=1’; $(formid).submit(); return false; } 后台刷新缓存，搞定。
