Question

我使用Borderlayout从dojo站点复制了一个示例。但是，当我在浏览器中加载时，将显示所有部分的整个数据。几秒钟后，内容为referh，数据显示正确。

这是我复制的代码。谢谢你的帮助

<head>
    <link rel="stylesheet" type="text/css" href="http://ajax.googleapis.com/ajax/libs/dojo/1.3/dijit/themes/tundra/tundra.css">

        { width: 100%; height: 100%; }

这看起来有点颠倒：你应该把你的javascripts放在head部分并首先加载dojo库。这不是你的问题。

当页面加载时，dojo会加载您“dojo.require”的所有模块，然后解析包含属性“dojoType”的所有标记并处理它们以进行渲染，这需要时间。

因此，您所看到的闪烁是解析小部件之前和之后的页面之间的差异。

您应该添加预加载器div并在解析页面后将其隐藏（请参阅this示例）。

这就是你的例子的样子：

<html>
    <head>

        <title>Preloader example</title>

        <!– every Dijit component needs a theme –>
        <link rel="stylesheet"
                href="http://o.aolcdn.com/dojo/1.4/dijit/themes/soria/soria.css">
        <style type="text/css">
                #preloader,
                body, html {
                        width:100%; height:100%; margin:0; padding:0;
                }
               #preloader {
                                  width:100%; height:100%; margin:0; padding:0;
                                  background:#fff
                                    url(’http://search.nj.com/media/images/loading.gif’)
                                    no-repeat center center;
                                    position:absolute;
                                    z-index:999;
                                }
                #borderContainer {
                        width:100%; height:100%;
                }


        </style>

                                        node:"preloader",
                                        onEnd: function(){
                                                dojo.style("preloader", "display", "none");
                                        }
                                }).play();
                        }
                        dojo.addOnLoad(function(){
                                // after page load, load more stuff (spinner is already spinning)
                                dojo.require("dijit.layout.BorderContainer");
                                dojo.require("dijit.layout.ContentPane");
                                dojo.require("dojo.parser");

                                // notice the second onLoad here:
                                dojo.addOnLoad(function(){
                                        dojo.parser.parse();
                                        hideLoader();
                                });
                        });

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/dojo/1.3/dojo/dojo.xd.js"></script>

if(dojo.isIE){
    addEvent(window, 'load', function(event) {
        dojo.parser.parse();
    });
}else{
    dojo.addOnLoad(function(){
        dojo.addOnLoad(function(){
            dojo.parser.parse();
        });
    });
}
function addEvent( obj, type, fn ) {
  if ( obj.attachEvent ) {
    obj['e'+type+fn] = fn;
    obj[type+fn] = function(){obj['e'+type+fn]( window.event );}
    obj.attachEvent( 'on'+type, obj[type+fn] );
  } else
    obj.addEventListener( type, fn, false );
}

禁用parseOnLoad并手动添加事件以解析小部件，即。

dojo borderlayout显示所有内容，闪烁然后正确重绘
