Question

我可以在使用jQuery的if语句中有多个条件吗？以下代码根本没有捕获错误。根据发布的建议进行了编辑

 $('.goRedIMG').on('click',function(event){
        var ischecked = false;
        var isOKtoSubmit = true;
        var alertMessage = 'No tools have been selected';
        var statusvar = '';
        var transferstatusvar = '';
        var action = $('#uTransaction option:selected').html();

        $('.chkaction').each(function() { //loop through each checkbox
            statusvar = $(this).closest('tr').children('.recordStatus').html();
            transferstatusvar = $(this).closest('tr').children('.transferstat').html()

            if($(this).prop('checked')) {
                ischecked = true;
                if((action == 'Transfer' && statusvar != 'ACTIVE') || (transferstatusvar != 'OK')){             
                    isOKtoSubmit = false;
                    alertMessage = 'One or more records cannot be transferred because status is not ACTIVE and transfer status is not OK';           
                }                  
            }
            if(action == 'Accept Transfer' && transferstatusvar != 'AWAITING'){                
                    isOKtoSubmit = false;
                    alertMessage = 'One or more records cannot be accepted or rejected because status is not ACTIVE or Transfer Status is not AWAITING';                    
                }              
       });
    if(isOKtoSubmit && ischecked !== false && action !== '--Select One--'){                 
            $('#toolActions').submit();         
        }else {
            alert(alertMessage);
        }       
    });

如果您在同一if参数中使用&&（AND）和||（OR），则需要对它们进行分组。

所以不要这样：

if(action == 'Transfer' && statusvar !== 'ACTIVE' || (transferstatusvar !== 'OK'))

你应该这样做：

if((action == 'Transfer' && statusvar != 'ACTIVE') || (transferstatusvar != 'OK'))

（另外，如果您想检查是否不等于，则不需要!==，而是执行!=）

使用jQuery中的if语句需要满足多个条件
