jQuery Ui.Layout.js——PrintArea.js学习
欢迎技术交流。 QQ：138986722
最近在学习jQuery、想做一个自己的页面框架、但是自己的美工水平实在不敢恭维。于是考虑到Ext什么的、但是Ext呢、从来没有接触过、就选择了jQuery、找了半天、也瞎摸了半天、英文水平不好(单词量基本上都是java语言或者Oralce语言的关键字、而且还不全)、学编程确实很吃力、官网上的东西如同天书、如果想好好深入的话、确实该好好学学英文了！
jQuery不光是提供Layout插件、还有很多很多的插件、csdn上搜索一下"jQuery插件"。出来的前几页标题基本一致~~~！！！非常之无语、希望csdn能对搜索引擎这块做做优化吧~~~！！！从官方网站(http://jqueryui.com/download)上下载、今天已经是2011年7月7号、一个特殊的日子、不是农历的七夕、而是"77事变"~~~、怀恋下革命先烈、你们永垂不朽！jQueryUI的版本已经发展到1.8.14了！发展快、很快、相当快！
OK、下载好过后、找到demos文件夹、点击里面的index.html页面、你就可以看到官网提供的UI示例了！附带示例代码的、推荐使用Mozilla FireFor浏览器查看、点击Open demo in a new window 然后在新的窗口中查看源代码、你会发现、有一个demos.css文件、它在你点击View Source 的时候没有的！如果你没有引用这个css文件、后果很严重、你会发现你跟示例一模一样的代码、就是出不来示例中的效果！用火狐还有一个好处就是、当你找不到某个页面引用文件的时候、只需要在查看页面源代码的时候、点击文件引用地址就能够看到里面的代码、复制一下、创建一个名称相同的文件、粘帖进去就OK了！里面的示例代码都有、我就不贴出来了！
然后在看看Layout~~~！！！这个东西需要单独下载、在另一个网站里面(http://layout.jquery-dev.net/demos.cfm)。点击DEMOC导航、然后会看到很多超链接、点击这些超链接你能看到Layout设计出的框架了、有很多超链接就意味着有很多框架~~~！！！如果你对页面布局非常熟悉的话、可以直接修改源代码、来达到你想要的效果！需要的js可以点击导航DOWNLOADS去下载、看看示例、在看看示例的页面源代码你就知道要什么js跟css了！
另外、我遇到一个问题、就是在火狐上能运行、但是到IE就出不了效果~~~这是一件很头大的事情、把新建jsp页面的时候生成的DOCTYPE节点增加点东西就OK了、加上：<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" " http://www.w3.org/TR/html4/strict.dtd"> 这个牵扯到协议方面的东西、我不是很清楚！

其中头部的falsh、我找了好久、硬是没有找到满意的、！如果大家有好的falsh素材请告诉我一下！
然后iframe控件对应的就是jQuery UI其他插件了！

其他部分就不贴了~~~！！！反正都是官方的示例、在来看看PrintArea.js对打印的支持吧：在主页面(index.jsp)中
<script type="text/javascript"> function PrintDiv(){ $("#myPrintArea").printArea(); } </script> <%-- 主体编辑区域 --%><div class="pane ui-layout-center" id="myPrintArea"> <iframe id="mainFrame" name="mainFrame" class="ui-layout-center" width="100%" height="100%" frameborder="0" scrolling="auto" src="Droppable/Modal_form.jsp"> </iframe> <input type="button" value="打印" onclick="PrintDiv();" /> </div>设置你需要打印部分的id、然后：$("#myPrintArea").printArea();注意、需要引用：
<script type="text/javascript" src="js/jquery.PrintArea.js" ></script>这个js、在官网上有下载资源：http://plugins.jquery.com/project/PrintArea点击View all releases到里面去选择版本！我选的是2.1版的、要注意、看清楚它的下载链接、狗日的小得老火、我找半天没找着！
在这里给大家贴出来jquery.PrintArea.js_4.txt 。
看看效果吧、有图有真相：
其中头部由于没有好的falsh就不弄出来丢人了、底部也是一样！！！
