當我玩露天份額時,發現很難跟蹤UI和javascript。你只能在HTML標籤中看到一些類名,但是你很難知道它們是如何構建的,以及這些分散的HTML代碼何時,如何以及如何渲染這樣一個奇特的頁面。alfresco的javascript(不是webscript)機制
有人可以幫助我嗎?請提供幾個例子並解釋它們的工作方式!
在此先感謝!

你應該嘗試用螢火蟲來瀏覽你的客戶端代碼。
Alfresco包括一堆文件,這些文件在服務器端都被拉到一起以便爲每個「頁面」提供服務。
我強烈推薦Jeff Potts的Alfresco Developer Guide(您可以立即購買並在線查看)。
下面是一些例子,希望能幫助你(它也可在維基)。大部分魔術都發生在JavaScript中(儘管佈局也部分在html中設置)。
比方說,你想建立一個dashlet。你必須在佈局像這樣幾個文件:
服務器端組件的位置:
$TOMCAT_HOME/share/WEB-INF/classes/alfresco/site-webscripts/org/alfresco/components/dashlets/...
和客戶端腳本在
$TOMCAT_HOME/share/components/dashlets...
所以 - 在服務器端,有一個dashlet.get.desc.xml - 定義URL並描述web腳本/ dashlet的文件。
還有一個dashlet.get.head.ftl文件 - 這就是你可以把一個< SCRIPT SRC =「...」 >標籤,這些將被包含在整個頁面的<頭>組件。
終於有具有<腳本類型=「文/ JavaScript的」 >標籤通常初始化您JS,平時喜歡新Alfresco.MyDashlet()。setOptions({一dashlet.get.html.ftl文件。 ..});
現在,有客戶端。就像我說過的,您有/share/components/dashlets/my-dashlet.js(或my-dashlet-min.js)中的客戶端腳本。該腳本通常包含一個自執行匿名函數定義你的Alfresco.MyDashlet對象,像這樣:所以現在你擁有了它
(function()
{
Alfresco.MyDashlet = function(htmlid) {
// usually extending Alfresco.component.Base or something.
// here, you also often declare array of YUI components you'll need,
// like button, datatable etc
Alfresco.MyDashlet.superclass.constructor.call(...);
// and some extra init code, like binding a custom event from another component
YAHOO.Bubbling.on('someEvent', this.someMethod, this);
}
// then in the end, there is the extending of Alfresco.component.Base
// which has basic Alfresco methods, like setOptions(), msg() etc
// and adding new params and scripts to it.
YAHOO.extend(Alfresco.MyDashlet, Alfresco.component.Base,
// extending object holding variables and methods of the new class,
// setting defaults etc
{
options: {
siteId: null,
someotherParam: false
},
// you can override onComponentsLoaded method here, which fires when YUI components you requested are loaded
// you get the htmlid as parameter. this is usefull, because you
// can also use ${args.htmlid} in the *html.ftl file to name the
// html elements, like <input id="${args.htmlid}-my-input"> and
// bind buttons to it,
// like this.myButton =
// so finally your method:
onComponentsLoaded: function MyDaslet_onComponentsLoaded(id) {
// you can, for example, render a YUI button here.
this.myButton = Alfresco.util.createYUIButton(this, "my-input", this.onButtonClick, extraParamsObj, "extra-string");
// find more about button by opening /share/js/alfresco.js and look for createYUIButton()
},
// finally, there is a "onReady" method that is called when your dashlet is fully loaded, here you can bind additional stuff.
onReady: function MyDashlet_onReady(id) {
// do stuff here, like load some Ajax resource:
Alfresco.util.Ajax.request({
url: 'url-to-call',
method: 'get', // can be post, put, delete
successCallback: { // success handler
fn: this.successHandler, // some method that will be called on success
scope: this,
obj: { myCustomParam: true}
},
successMessage: "Success message",
failureCallback: {
fn: this.failureHandler // like retrying
}
});
}
// after this there are your custom methods and stuff
// like the success and failure handlers and methods
// you bound events to with Bubbling library
myMethod: function (params) {
// code here
},
successHandler: function MyDAshlet_successHandler(response) {
// here is the object you got back from the ajax call you called
Alfresco.logger.debug(response);
}
}); // end of YAHOO.extend
}
。如果你瀏覽alfresco.js文件,你會發現你可以使用的東西,比如Alfresco.util.Ajax,createYUIButton,createYUIPanel,createYUIeverythingElse等。你也可以通過嘗試玩,比如說我的網站或我的任務dashlets,他們並不那麼複雜。
而且Alfresco會將你的html.ftl部分放在頁面主體,你的頭部。在頁頭和最終用戶FTL部分加載一個網頁,其中:
試着弄明白,你就可以得到其他更復雜的東西。 (也許:))
