FireSpider and pyGtranslator on GitHub

Since I'm getting so many bug reports and improvement wishes for those two tiny apps I decide to push the source to GitHub repository, available to any one to contribute. I haven't touch them for a while also the code isn't shiny, but any way we are all learning. I wish i could play more with it but I'm currently busy with other things also switching the job and so...

Dynamic select boxes

These days i was working on a project, where i needed dynamically loading select boxes. I first tried mootools native methods like removing and injecting new option elements in to select element. That worked just fine in FF, but as you expect in IE did not. IE's select box stood unchanged. I remember while ago i have to re-inject the whole select box to see the changes in IE.

According to DOM, there is a better way. HTMLSelectElement support add and remove method that work in all major browsers. So i have implemented three basic methods for mootools Element class.

Element.implement({
	removeAllOptions: function() {
		if(this.get('tag')!='select') return this;
		for(var i=this.options.length-1;i>=0;i--) this.remove(i);
		return this;
	},

	addOption: function(text,value) {
		if(this.get('tag')!='select') return this;
		var optn = new Element('option');
		if(text) optn.text = text;
		if(value) optn.value = value;
		this.options.add(optn);
		return this;
	},

	removeOption: function(prop,value){
		if(this.get('tag')!='select') return this;
		for(var i=this.options.length-1;i>=0;i--) {
			if (prop=='selected' && this.options[i].selected) this.remove(i);
			if (prop=='value' && this.options[i].value==value) this.remove(i);
			if (prop=='text' && this.options[i].text==value) this.remove(i);
			if (prop=='index' && i==value) this.remove(i);
		}
		return this;
	}
});

Methods hopefully already explaining their self.

USAGE

// remove all options or empty select box
$('selectbox').removaAllOptions();

// add options, one after another
$('selectbox').addOption('One',1).addOption('Two',2).addOption('Two',3);

// removing options 
$('selectbox').removeOption('text','One');
$('selectbox').removeOption('value',2);
$('selectbox').removeOption('selected');
$('selectbox').removeOption('index',0);

happy selecting ;)

Simple combining of multiple javascript and css files

I've already wrote about "firefox only includes styles form .css files" and I found out that isn't quite true. Actually firefox doesn't care about the css file extension, but only relay on header Content-Type: text/css. If you as usual have .css file, apache will take care of right content-type, otherwise you will have to take care about it.

header('Content-Type: text/css');

I came across this when i was writing this script:

## combine.php

// Define path prefix
$prefix = realpath('.');

if($_GET['js']) {
	header('Content-Type: application/x-javascript');
	$data = Array('path'=>$prefix.'/template/js/','files'=>$_GET['js'],'ext'=>'.js');
} elseif($_GET['css']) {
	header('Content-Type: text/css');
	$data = Array('path'=>$prefix.'/template/styles/','files'=>$_GET['css'],'ext'=>'.css');
} else exit();

foreach(explode(',',$data['files']) as $file) {
	if($file && file_exists($data['path'].$file.$data['ext'])) readfile($data['path'].$file.$data['ext']);
}

Simple few lines of code, but already do the trick. That will minimise number of server requests and benefit in faster page loading.

Defining the path and file extension is important, otherwise you may expose some other scripts source or even worse, some system files.

Usage in page head

<link rel="stylesheet" type="text/css" href="combine.php?css=style,forms" />
<script type="text/javascript" src="combine.php?js=mootools,validate,fx"></script>

Hope you like it, otherwise If you want more advanced solution try minify.

cheers
