错误：接近“％”：语法错误代码：phonegap sqlite中的5

Question

我是phonegap的新手 任何人都可以帮助我遵循以下语法 -

var frm_dt=date('now', '+1 day', 'start of month');  // 1st date of month

var to_dt=date('now', '+1 month', 'start of month', '-1 day'); // last date of month

tp.executeSql('SELECT Sum(CreditVal) as CreditVal FROM ExpenseTbl where date_added  between ? and ? ;',[frm_dt,to_dt],function(tp, result) 
{ 
     if (result != null && result.rows != null) 
     {                                                                                                                                                                                                                  
         var row = result.rows.item(0); 
         ('#lblMonthlyIncm').html('');
         $('#lblMonthlyIncm').append(row.CreditVal);                                                                                             
     }

您是否遗漏了$上的('#lblMonthlyIncm').html('');？
