【JS】jQuery中将数组转换成字符串join()和push()使用

<script type = text/javascript>
       $(document).on(‘click‘, ‘.sure‘, function() {
        var =[];
        var highlights = new Array();  //或者var highlights  = [];
         $(‘.plan-ipt input‘).each(function(){
           if($(this).val()!=‘‘)
            {
                highlights.push($(this).val());
            }
         });
         var arr = highlights.join(‘&‘);　　//arr是以&分割的字符串
         $("#all_plan").val(arr);   
        }) 
</script>
