Javascript Issue

function ValidateLeave() { var LeaveCount=document.getEl("txtTotalLeaves"); var Days=document.getEl("txtDays"); if( LeaveCount.value==0) { alert("Sorry You Have No Leaves Available"); return false; } else if (LeaveCount.value < Days.value) { alert(LeaveCount.value); alert(Days.value); alert("Sorry!Check your available leaves!"); return false; } else { return true; } } The above code throws error for me, the issue came because of wrong type casting.Here is an useful link for type casting www.jibbering.com#tcInt The below code will work fine. function ValidateLeave() { var LeaveCount=document.getEl("txtTotalLeaves"); var Days=document.getEl("txtDays"); if( LeaveCount.value*1==0) { alert("Sorry You Have No Leaves Available"); return false; } else if (LeaveCount.value*1 < Days.value*1) { alert(LeaveCount.value); alert(Days.value); alert("Sorry!Check your available leaves!"); return false; } else { return true; } }
