Javascript - What is the checking order for the condition statement


Javascript - What is the checking order for the condition statement

hop of those help? For the second line console.log(myObj.pro != null && myObj.pro.val != null ? 0 : 1);, myObj.pro evaluates to undefined which is then compared to null and that returns false. We know that in an AND comparison, Javascript ignores the right hand side of the AND when the left hand side evaluates to false. This reasonable behaviour prevents the interpreter from encountering the exception-bound right hand side code which is essentially undefined.val
The third line just goes ahead and evaluates undefined.val which throws an exception and halts interpretation.

it fixes the issue Yes, you should use && not AND.
Since I am not eloquent enough to explain it, here's a good post about it, thanks to the commentator ;)

wish help you to fix your issue PHP has indeed a mechanic named short-circuit: http://php.net/manual/en/language.operators.logical.php#example-140
If the first operand of a logical OR is true, then the second part isn't evaluated, and the function isn't called.

wish helps you For some reason, you have an array in your condition. I think you meant to use parentheses for grouping, not brackets. I fixed that and now it's working.
code :
//Check for Input Field

$('#submit').click(function(){
if (($.trim($("#dropDownShops_1").val()) == "" || $.trim($("#ReceiptField_1").val()) == "") && ($.trim($("#dropDownShops_2").val()) == "" || $.trim($("#ReceiptField_2").val()) == "")) {

  console.log("Receipt_Field_Error wrong");
  $("#ReceiptInput_Field_Error").html("* Please fill in appropriate fields.");
  $("#ReceiptInput_Field_Error").fadeIn();

  setTimeout(function() {
    $("#ReceiptInput_Field_Error").fadeOut();
  }, 5000);

} else {

  //Check if American Card is used: Min spending of SGD$120 else will be min spending of SGD$150

  //AmexCard User
  if ($('#AmaxCardField').is(':checked')) {

    //Check that the input value field is SGD$120 or more else, inform that minimum spending is SGD120
    if (($("#ReceiptField_1").val() >= 120) || ($("#ReceiptField_2").val() >= 120) || (
      (($("#ReceiptField_1").val()) + ($("#ReceiptField_2").val())) >= '120'
    )) {

      //Condition Passed
      console.log("Amex user and spent more than $120");

      alert("Amex user and spent more than $120");
    } else {
      //inform that minimum spending is SGD120

      $("#ReceiptInput_Field_Error").html("* Your Minimum Spending should be $120 to qualify.");
      $("#ReceiptInput_Field_Error").fadeIn();

      setTimeout(function() {
        $("#ReceiptInput_Field_Error").fadeOut();
      }, 5000);
    }

  } else if ((!$('#AmaxCardField:checked').length)) {

    //Check that the input value field is SGD$150 or more else, inform that minimum spending is SGD150
    if (($("#ReceiptField_1").val() >= '150') || ($("#ReceiptField_2").val() >= '150') || (
      (($("#ReceiptField_1").val()) + ($("#ReceiptField_2").val())) >= '150'
    )) {


      console.log("Amex user and spent more than $150");

      alert("Amex user and spent more than $150");
    } else {
      //inform that minimum spending is SGD120

      $("#ReceiptInput_Field_Error").html("* Your Minimum Spending should be $150 to qualify.");
      $("#ReceiptInput_Field_Error").fadeIn();

      setTimeout(function() {
        $("#ReceiptInput_Field_Error").fadeOut();
      }, 5000);

    }
  }
}
  });

Does that help And, nand, or and nor operators in VHDL are short-circuit operators in some cases. The behavior depends on the operands types.
You're using type std_logic, which is not listed:

will be helpful for those in need I am writing a program to detect basic syntax errors in "code", I have a string that split up into lines and store it in an Array, I then check if each lines ends with one of the appropriate symbols using the .endsWith() function, below is my code: , Your condition in the if statement is not correct.
Try this:

if (!line.endsWith(";") && !line.endsWith("}")
