最常见的WordPress函数
esc_js ( $text )
esc_js: 这个函数用于转义一个字符串,以便在JavaScript代码中使用。
消除单引号、`"`、`<`、`>`、`&`,并修复行尾。
在JS中对文本字符串进行转义。它旨在用于内联JS(在一个标签属性中,例如`onclick=””…””)。注意,字符串必须在单引号中。{@see ‘js_escape’}过滤器也适用于此。
function esc_js( $text ) { $safe_text = wp_check_invalid_utf8( $text ); $safe_text = _wp_specialchars( $safe_text, ENT_COMPAT ); $safe_text = preg_replace( '/&#(x)?0*(?(1)27|39);?/i', "'", stripslashes( $safe_text ) ); $safe_text = str_replace( "r", '', $safe_text ); $safe_text = str_replace( "n", '\n', addslashes( $safe_text ) ); /** * Filters a string cleaned and escaped for output in JavaScript. * * Text passed to esc_js() is stripped of invalid or special characters, * and properly slashed for output. * * @since 2.0.6 * * @param string $safe_text The text after it has been escaped. * @param string $text The text prior to being escaped. */ return apply_filters( 'js_escape', $safe_text, $text ); }
