var count;//which needs to be compared with BValue 
var AValue = $("#txtA").val(); 
var BValue = $("#txtB").val(); 

if (AValue == "") { 
      alert("Enter AValue and continue"); 
     } else if (BValue == "") { 
      alert("Enter To BValue and continue"); 
     } else if (AValue > BValue) { 
      alert("AValue should be lesser than To BValue"); 
     } else if (AValue == "" || BValue == "") { 
      alert("Please enter the AValue and BValue to continue"); 
     } else if (AValue == "0") { 
      alert("Invalid AValue"); 
     } else if (BValue > count) { 
      alert("Invalid BValue"); 
     } else { 
      // do some operations here 
     }

所有條件都經過良好，但這種BValue > count被觸發我雖然滿足條件

我想你忘了關括號。因此：if（$（「Value ==」）） – 2016-07-30 04:51:41

if（$（「AValue ==」）「if not（AValue == ==」）我在OP – guradio

語法錯誤中看不到'BValue> 「」） –

檢查該工作示例。

要麼使用：

if (AValue == ""){ 

}

或者

if (($("#txtA").val()) == ""){ 

}
