时，我有一个示例代码：错误使用自静电功能
class Assets {
public static $my_static = '';
public static function custom_js()
{
return self::add_custom_js();
}
public static function add_custom_js($str)
{
return self::$my_static = $str;
}
}
和PHP
<?php
Assets::add_custom_js("ABC");
?>
<html>
...
<?php echo Assets::custom_js(); ?>
...
</html>
错误不能显示的数据串是 “ABC”
我想你想返回$my_static的值得到ABC的echo Assets::custom_js();。考虑以下几点：
class Assets {
public static $my_static = '';
public static function custom_js()
{
// return self::add_custom_js();
return self::$my_static; //This is what you want i believe
}
public static function add_custom_js($str)
{
return self::$my_static = $str;
}
}
你必须从custom_js()返回$my_static所以你的类应该如下：
<?php
class Assets {
public static $my_static = '';
public static function custom_js()
{
return self::$my_static; //<-------------change this line
}
public static function add_custom_js($str="")
{
return self::$my_static = $str;
}
}
?>
调用add_custom_js（）内的Custom_JS当你不传递参数（） –
