您可以将译文包装在printf 作用printf （或sprintf 当您不想立即打印到屏幕上时）允许您在字符串中放置占位符。请参阅所有类型说明符的文档

使用\\uuuu（）而不是\\u e（），因为printf已经输出到屏幕。

$no_people = 5;

printf( __( \'There are %d <span>people</span> in this country.\', \'textdomain\' ), $no_people );

Edit

$no\\U人数=5人；

$nostores = sprintf( __( \'There are %d <span>people</span> in this country.\', \'textdomain\' ), $no_people );

wp_localize_script( \'store-locator\', \'storelocatorjstext\', array(
    \'nostores\'   => $nostores
) );
