Я передаю массив PHP функции javascript. Единственный способ, которым я это знаю, – создать массив js из массива PHP и передать его функции js. Но это создает огромный кусок кода для передачи (см. Код ниже – есть намного больше, но я уверен, что вы получите общую идею). Я подозреваю, что существует более эффективный метод. Кто-нибудь захочет поделиться им со мной? Благодаря!

Используйте JSON. посмотрите, почему JSON над XML: http://thephpcode.blogspot.com/2008/08/why-json-over-xml-in-ajax.html
Использовать json в PHP просто:
<?php echo '<script type="text/javascript">/* <![CDATA[ */'; echo 'var train = '.json_encode($array); echo '/* ]]> */</script>'; ?>
переменная train
в Javascript будет объектом, содержащим свойства и массивы на основе вашего $array
PHP $array
.
Чтобы проанализировать или перебрать объект поезда, вы можете использовать for ... in
операторах для массивов JSON и напрямую использовать object.property для объектов JSON.
Видеть это:
<?php $array = array(array('id'=>3,'title'=>'Great2'),array('id'=>5,'title'=>'Great'),array('id'=>1,'title'=>'Great3')) echo '<script type="text/javascript">/* <![CDATA[ */'; echo 'var train = '.json_encode($array); echo '/* ]]> */</script>'; ?>
Выход будет:
var train = [{id:3,title:'Great2'},{id:5,title:'Great'},{id:1,title:'Great3'}];
переменная train
становится массивом объектов. [] Квадратные квадратные скобки – это массивы, содержащие больше массивов или объектов. {} фигурные скобки – это объекты, у них есть свойства к ним.
Чтобы перебрать переменную train
:
<script type="text/javascript"> var train = [{id:3,title:'Great2'},{id:5,title:'Great'},{id:1,title:'Great3'}]; for(i in train){ var t = train[i]; // get the current element of the Array alert(t.id); // gets the ID alert(t.title); // gets the title } </script>
Просто! Надеюсь, что это действительно помогает.
json_encode. См. http://us3.php.net/manual/en/function.json-encode.php
Более компактный способ кодирования структур данных Javascript называется JSON .
Начиная с PHP 5.2.0, вы можете использовать следующую функцию для выделения некоторого JSON: json_encode () .
Вы всегда можете использовать XMLHttpRequest для загрузки его как JSON или XML .
