JavaScript OnMouseOver 解析错误：语法错误，意外的 T_STRING

Question

当我在 中编写此代码时，

<a href="'.get_permalink($niphell[post_id]).' " onmouseover="mns('#msnbtn-'.($j+1).'','#msn-'.($j+1).'','.mnsli','.mnsbtbg');">

我收到此错误

Parse error: syntax error, unexpected T_STRING in /home/azerinfo/public_html/wp-content/themes/anntheme/scroller.php on line 125

jQuery 代码：

<script type="text/javascript">
function mns(e,d,c,s){
   jQuery(s).removeClass('aktif');
   jQuery(e).addClass('aktif');
   jQuery(c).css({display: 'none'});
   jQuery(d).css({display: 'block'});
}
mns('#msnbtn-1','#msn-1','.mnsli','.mnsbtbg');
</script>

更新：

<div class="mns">
<div class="crv">

Answer 1

您的问题是 JS 使用单引号以及 PHP 单引号。 PHP 无法判断某些单引号不是为它设计的。

举个例子，这里：

    $ust .= '<li><a href="'.get_permalink($niphell[post_id]).'" onmouseover="mns('#msnbtn-'.($j+1).'','#msn-'.($j+1).'','.mnsli','.mnsbtbg');">
            P             P                                  P                   J                       

您打算由 JS 解释第四个单引号，但 PHP 正在捕获它。

您可能应该更改为在 PHP 中使用双引号，并在 HTML 中转义所需的双引号，如下所示：

    $ust .= "<li><a href=\"".get_permalink($niphell[post_id])."\" onmouseover=\"mns('#msnbtn-'.($j+1).'','#msn-'.($j+1).'','.mnsli','.mnsbtbg');\">

等等。
