Mit Javascript Bild wechseln und cachen OHNE Blitzer
Für folgendes wird Mootools (http://mootools.net) benötigt, das ich eigentlich standardmässig verwende.
- var loaded = new Array();
- function in_array(item,arr) {
- for(p=0;p<arr.length;p++) if (item == arr[p]) return true;
- return false;
- }
- function switch_bg_image(where, what) {
- if (!in_array(what, loaded)) {
- temp = new Image();
- temp.src = what;
- temp.onload = function () {
- window.addEvent('domready', function() {
- $(where).setStyle('background-image',
- "url(" + temp.src + ")");
- loaded[loaded.length] = what;
- });
- }
- } else {
- window.addEvent('domready', function() {
- $(where).setStyle('background-image',
- "url(" + what + ")");
- });
- }
- }
- function switch_image(where, what) {
- if (!in_array(what, loaded)) {
- temp = new Image();
- temp.src = what;
- temp.onload = function () {
- window.addEvent('domready', function() {
- $(where).src = temp.src;
- loaded[loaded.length] = what;
- });
- }
- } else {
- window.addEvent('domready', function() {
- $(where).src = what;
- });
- }
- }
Simpler Klassen Autoload mit SPL
- <?php
- function mein_autoload($class_name) {
- require_once 'class/' . $class_name . '.class.php';
- } else {
- throw new Exception('Konnte die Klasse \'' .
- $class_name . '.class.php' . '\' nicht öffnen');
- }
- }
- spl_autoload_register('mein_autoload');
- ?>

Array sortieren und Umlaute + Reihenfolge beachten.
- <?php
- function make_sort_function($field) {
- $from = "array('Ü', 'ü', 'Ö', 'ö', 'Ä', 'ä', 'ß',
- '&Uumml', 'ü', 'Ö', 'ö',
- 'Ä', 'ä', 'ß')";
- $to = "array('Ue', 'ue', 'Oe', 'oe', 'Ae', 'ae', 'ss', 'Ue',
- 'ue', 'Oe', 'oe', 'Ae', 'ae', 'ss')";
- $code = "\$a = str_replace($from, $to, \$a['$field']);\n";
- $code .= "\$b = str_replace($from, $to, \$b['$field']);\n";
- $code .= "if (\$a == \$b) return 1;";
- $code .= "return strnatcmp(\$a, \$b);";
- }
- function sort_array($array, $order = SORT_ASC) {
- $from = "array('Ü', 'ü', 'Ö', 'ö', 'Ä', 'ä', 'ß',
- '&Uumml', 'ü', 'Ö', 'ö',
- 'Ä', 'ä', 'ß')";
- $to = "array('Ue', 'ue', 'Oe', 'oe', 'Ae', 'ae', 'ss', 'Ue',
- 'ue', 'Oe', 'oe', 'Ae', 'ae', 'ss')";
- $code = "\$a = str_replace($from, $to, \$a);\n";
- $code .= "\$b = str_replace($from, $to, \$b);\n";
- $code .= "if (\$a == \$b) return 1;";
- $code .= "return strnatcmp(\$a, \$b);";
- if ($order != SORT_ASC) {
- } else {
- return $array;
- }
- }
- function sort_array_by_field($array, $field,
- $order = SORT_ASC) {
- $function = make_sort_function($field);
- if ($order != SORT_ASC) {
- } else {
- return $array;
- }
- }
- ?>
str_replace für Javascript
- function str_replace (search, replace, subject) {
- var result = "";
- var oldi = 0;
- for (i = subject.indexOf (search); i > -1; i = subject.indexOf (search, i)) {
- result += subject.substring (oldi, i);
- result += replace;
- i += search.length;
- oldi = i;
- }
- return result + subject.substring (oldi, subject.length);
- }
in_array für Javascript
Ist ziemlich simpel, kann natürlich auch jeder selbst schreiben, aber die Bequemen kopieren es sich:
Gefunden auf: Dodwin's Blog
- function in_array(item,arr) {
- for(p=0;p<arr.length;p++) if (item == arr[p]) return true;
- return false;
- }
Gewählte Optionen eines Multiple Select Menus per Javascript ermitteln

- if (select_menu.options[ i ].selected) {
- array_selected.push(select_menu.options[ i ].value);
- }
- }
- return array_selected;
- }
