Sometimes I use this latin text as dummy content in my projects:

HowTo override and substitute document.write function in JavaScript (sample)

It is pretty simple to wrap document.write function in JavaScript.

For example - using closures:

<script id="source" type="text/javascript">
    function wrapString(str) {
        return "(" + str + ")";
    }
    
    document.write = function(w) {
        return function(s) {
            w.call(this, wrapString(s));
        }
    }(document.write);

    document.write("Hello");
    document.write("world");
</script>

This "advanced piece of engineering" prints string: (Hello)(world)

HowTo simulate Googlebot

Googlebot is Google's web crawling robot, which finds and retrieves pages on the web and hands them off to the Google indexer.
Googlebot visits sites with special value in his HTTP request header.

It uses special user-agent string:
"Mozilla/5.0 (compatible; Googlebot/2.1; http://www.google.com/bot.html)"

It is possible to simulate Googlebot from the shell script via wget program.

Like this:

#!/bin/bash

TEST_URL="http://digg.com/"

FIREFOX_USERAGENT_STRING="Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.14) Gecko/20080404 Firefox/2.0.0.14"
GOOGLEBOT_USERAGENT_STRING="Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html)"

#get page for firefox browser
wget -c --user-agent="$FIREFOX_USERAGENT_STRING" --output-document=firefox.html "$TEST_URL"

#get page for google bot
wget -c --user-agent="$GOOGLEBOT_USERAGENT_STRING" --output-document=googlebot.html "$TEST_URL"


This script may be useful for testing of site's search engine optimization.

Xml elements and attributes in the ExtJS table

Ext JS - JavaScript Library is pretty powerful JavaScript/AJAX framework for building of Rich Internet Applications.

I've used it in my last public web project: Ubuntu index.


ExtJS has set of useful UI controls, internal components and strong AJAX, XML and JSON support.

E.g. you can present this XML file:

items.xml

<?xml version="1.0"?>

<items>

    <item id="alien-arena">
        <name>Alien Arena</name>
    </item>

    <item id="nexuiz">
        <name>Nexuiz</name>
    </item>

    <item id="openarena">
        <name>OpenArena</name>
    </item>

</items>

as a table via this HTML + JavaScript code:

table.html

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
    <title>ExtJS Table Sample</title>
    <link rel="stylesheet" type="text/css" href="ext/resources/css/ext-all.css"/>
    <script type="text/javascript" src="ext/adapter/ext/ext-base.js"></script>
    <script type="text/javascript" src="ext/ext-all.js"></script>
</head>
<body>

<script type="text/javascript">
    Ext.onReady(function() {
        var reader = new Ext.data.XmlReader({record: "item"},
                [{name: "id", mapping:"@id"}, "name"]);

        var store = new Ext.data.Store({url: "items.xml", reader: reader});

        var columnModel = new Ext.grid.ColumnModel([
        {header: "Id", dataIndex: "id"},
        {header: "Name", dataIndex: "name"}]);

        var table = new Ext.grid.GridPanel({
            store: store,
            height: 200,
            cm: columnModel,
            renderTo: "table"
        });
        store.load();
    });
</script>

<div id="table" style="width:300px; height:200px;"></div>
</body>
</html>
