SyntaxError：无效的正则表达式标志a

Question

您好我正在使用JQuery Zoomer并代替larg Image path我正在给这个

<script type="text/javascript">
    jQuery(document).ready(function($){ //fire on DOM ready
        $('img.zoomer_panel').addpowerzoom({
        defaultpower: 2,
        powerrange: [2,5],  
        largeimage: "/editor.images/images/Ranches/bb-brooks-ranch/BB-Brook-North-Map.jpg",
        magnifiersize: [100,100] //<--no comma following last option!
    }) /**/
})
</script>   

它给了我这个错误
