簡單的excel導入數據庫

html代碼
<input type="file" name="an" id="import_file" onchange="changes()"/>
<a href="javascript:void(0)" onclick="importExcel()" class="easyui-linkbutton" data-options="iconCls:'icon-save'">提交</a>
js代碼
function importExcel(){
            var names=jQuery("#import_file").val();
            if(names==null||names==""){
                jQuery.messager.alert('系統提示','請選擇要導入的文件模版！','');
                return;
            }
            var isValid = jQuery("#submitExcel").form('validate');
            if(isValid){
                // 提交導入表單
                jQuery("#submitExcel").form("submit",{
                    url :   '$!link.getContextPath()/base/baseStation_importExcel.htm',
                });
            }
        }
