jquery 中判斷 checkbox 是否選取的不要再用 attr 要改用 prop
最近為了在 iframe 中的 history.goback 的問題,把後台的 jquery 升級到 1.10.1 版,結果發生讓 checkbox 全選的語法無效,原來是 attr('checked') 在 1.10.1 版中不會隨著 checkbox 是否選取而改變。


<input type="checkbox" onclick="if ($(this).attr('checked')) { $('.cbProducts').attr('checked', true) } else { $('.cbProducts').attr('checked', false) }" />

要換成

<input type="checkbox" onclick="if ($(this).prop('checked')) { $('.cbProducts').prop('checked', true) } else { $('.cbProducts').prop('checked', false) }" />


不過很麻煩節是,若是 jquery 1.5.x 及以前的版本是不支援 prop 的,請參考文章:
http://blog.xuite.net/vexed/tech/44905647-jQuery+1.6+.attr()+%E5%92%8C+.prop()

我先把後台的 MasterPageWithForm.master 由 1.10.1 改回 1.6.2 版, MasterPage.master 和 MasterPage_NoMenu.master 兩支程式的 jquery 由 1.5.1 改到 1.6.2 版。未來要升級 1.10.1 以上的版本時可能會需要大工程把 attr 改為 prop。 或是考慮用 

$.fn.attr = $.fn.prop;

來把整個 attr 改為 prop

整理一下最近 IE9 (或以下) 的問題,順便補一個 Firefox 的問題
IE一直到 IE10 才比較支援一般正常瀏覽器的功能
IE9 以下常常要做一些特別的處理 稍微整理一下

1. input, textarea 的 "placeholder" 屬性,IE10 以上才支援,建議偵測 IE9 以下版本時,特別跑 js 用 onfocus, onblur    來處理

    function setPlaceholder(e) {
        var placeholder = $(this).attr('placeholder');
        if ($(this).val().length == 0) {
            $(this).css("color", "#b2b2b2").val(placeholder);
        }

        $(this).focus(function (e) {
            if ($(this).val() == placeholder) { $(this).css("color", "#666").val(""); }
        });

        $(this).blur(function (e) {
            if ($(this).val().length == 0) { $(this).css("color", "#b2b2b2").val(placeholder); }
        });
    }

    if (Is_LTE_IE9) {
        $('input[placeholder]').each(setPlaceholder);
        $('textarea[placeholder]').each(setPlaceholder);
    }


2. <input type=file /> 不能用 js 去 click,必須要user真的去點他, js 才抓得到檔案,不然傳到server也是空的
   
3. IE9 的 js console.log 必須在 "偵錯模式" 下才能使用,所以js程式完成後,要記得把 console.log 清掉或是註解掉
   不然一般 IE9 的 User 會跳出 js 的錯誤,然後 js 就停了。(這個問題必須在純IE9的瀏覽器才能發現,IE10模擬IE9也發    現不到)

4. Firefox 問題: 當我們要算div的寬高時,他本身必須 display:block 才能算的出來,不然會是 0,
   但是 Firefox 連隱藏iframe 裡的 html > div 都會回傳 0,必須把 iframe 設為 display:block;visibility:hidden
  才能算出裡面div的寬高

網頁端不同時區之時間顯示

由於網站的user來自全世界各地,而我們網站產生的時間卻是Server的時間
因此需要使用javascript來做一些轉換,讓user看到是他當地的時間

1. Server端產生具有時區的時間字串,用特定的span + class把它包起來, 時間格式 DateTime.ToUniversalTime().ToString("r")
     
<span class="timeString">Fri, 31 Aug 2012 10:57:04 GMT</span>

2. Client端利用jQuery於網頁load的時候將所有時間轉換成當地時間
    這個地方我用了  date.format.js 來轉換成當地時間 (參考  http://blog.stevenlevithan.com/archives/date-time-format  )
   

     $(".timeString").each(function () {
            var content = $(this).text();
            var d = new Date(content);
            if (!isNaN(d)) $(this).text(d.format("yyyy-mm-dd hh:MM tt"));
        }); 
   

這樣user看到的時間就不會錯了

global.asax 的事件
從 http://blog.ie-soft.de/post/2007/12/globalasax-events.aspx  抄來的. 留作參考

HttpApplication Events:

Application_AcquireRequestState
Occurs when ASP.NET acquires the current state (for example, session state) that is associated with the current request. 

Application_AuthenticateRequest
Occurs when a security module has established the identity of the user. 

Application_AuthorizeRequest
Occurs when a security module has verified user authorization. 

Application_BeginRequest
Occurs as the first event in the HTTP pipeline chain of execution when ASP.NET responds to a request. 

Application_Disposed
Adds an event handler to listen to the Disposed event on the application. 

Application_EndRequest
Occurs as the last event in the HTTP pipeline chain of execution when ASP.NET responds to a request. 

Application_Error
Occurs when an unhandled exception is thrown. 

Application_PostAcquireRequestState
Occurs when the request state (for example, session state) that is associated with the current request has been obtained. 

Application_PostAuthenticateRequest
Occurs when a security module has established the identity of the user. 

Application_PostAuthorizeRequest
Occurs when the user for the current request has been authorized. 

Application_PostMapRequestHandler
Occurs when ASP.NET has mapped the current request to the appropriate event handler. 

Application_PostReleaseRequestState
Occurs when ASP.NET has completed executing all request event handlers and the request state data has been stored. 

Application_PostRequestHandlerExecute
Occurs when the ASP.NET event handler (for example, a page or an XML Web service) finishes execution. 

Application_PostResolveRequestCache
Occurs when ASP.NET bypasses execution of the current event handler and allows a caching module to serve a request from the cache. 

Application_PostUpdateRequestCache
Occurs when ASP.NET completes updating caching modules and storing responses that are used to serve subsequent requests from the cache. 

Application_PreRequestHandlerExecute
Occurs just before ASP.NET begins executing an event handler (for example, a page or an XML Web service). 

Application_PreSendRequestContent
Occurs just before ASP.NET sends content to the client. 

Application_PreSendRequestHeaders
Occurs just before ASP.NET sends HTTP headers to the client. 

Application_ReleaseRequestState
Occurs after ASP.NET finishes executing all request event handlers. This event causes state modules to save the current state data. 

Application_ResolveRequestCache
Occurs when ASP.NET completes an authorization event to let the caching modules serve requests from the cache, bypassing execution of the event handler (for example, a page or an XML Web service). 

Application_UpdateRequestCache
Occurs when ASP.NET finishes executing an event handler in order to let caching modules store responses that will be used to serve subsequent requests from the cache. 

Application_Init
This method occurs after _start and is used for initializing code. 

Application_Start
As with traditional ASP, used to set up an application environment and only called when the application first starts.

Application_End
Again, like classic ASP, used to clean up variables and memory when an application ends.

Session Events:

Session_Start
As with classic ASP, this event is triggered when any new user accesses the web site.

Session_End
As with classic ASP, this event is triggered when a user's session times out or ends. Note this can be 20 mins (the default session timeout value) after the user actually leaves the site.

Profile Events:

Profile_MigrateAnonymous
Occurs when the anonymous user for a profile logs in.

Passport Events:

PassportAuthentication_OnAuthenticate
Raised during authentication. This is a Global.asax event that must be named PassportAuthentication_OnAuthenticate.
 

Possibly more events defined in other HttpModules like:

System.Web.Caching.OutputCacheModule
System.Web.SessionState.SessionStateModule
System.Web.Security.WindowsAuthentication
System.Web.Security.FormsAuthenticationModule
System.Web.Security.PassportAuthenticationModule
System.Web.Security.UrlAuthorizationModule
System.Web.Security.FileAuthorizationModule
System.Web.Profile.ProfileModule

CKEditor 中貼上剪貼簿(clipboard) 中的圖片
在 Chrome 中, 可以直接把圖片用 ajax 傳到 Server 上. 請參考 在 Chrome 中, 直接把剪貼簿中的圖片用貼上的方式上傳到 Server 但若是要在 CKEditor 中貼上圖片, 會遇到一些問題, 主要的原因是 Past Event 綁定的方法不太一樣: 其中 ".<% = me.txtContent.ClientId %>"  要換成 textarea 的 id

$(document).ready(function () {
CKEDITOR.replace('<% = me.txtContent.ClientId %>', {
on: {
instanceReady: function (ev) {
this.dataProcessor.writer.setRules('p', {
indent: false, //縮排
breakBeforeOpen: true, // <P>之前是否換行
breakAfterOpen: true, // <P>之後是否換行
breakBeforeClose: false, // </P>之前是否換行
breakAfterClose: true // </P>之後是否換行
});
}
},
toolbar: 'basic'
});
});

$(document).ready(function () {
if (parseInt(window.navigator.appVersion.match(/Chrome\/(\d+)\./)[1]) >= 12) {
function bindPasteInCK() {
$("iframe").contents().find("body").bind('paste', imagePasteOnPaste);
}

CKEDITOR.instances.<% = me.txtContent.ClientId %>.on("instanceReady", bindPasteInCK);
}
});
