JavaScript function is not callable

Currently facing a strange issue or maybe it's just me missing something obvious. I've searched for the error but couldn't find the right solution.

I am attempting to execute some Javascript code when the key "/" is pressed in a text box.

Below is the provided code snippet:

function ClockIn(){
    var kb_press = event.keyCode;
    if(kb_press == 47)
    {
        alert("you are clocking in");
        if(document.ClockIn.status.value === "IN"){
            alert("You Cant Clock in while you are already Clocked in\n Please try again!")
            document.ClockIn.tx_Barcode.value, document.ClockIn.status.value, document.ClockIn.name.value = "";
        }
    }
}
<form method="POST" name="ClockIn">
<lable>Type your BarCode <input type="text" name="tx_Barcode" id="tx_Barcode" class="tx_Barcode" onkeypress="ClockIn()" ></lable><br>
<lable>What is your Name? <input type="text" name="name"></lable><br>
<lable>Your current Status <input type="text" name="status"></lable><br>
</form>

The problem encountered: "ClockIn is not a function"

Answer №1

The issue at hand is the naming conflict with your "ClockIn" form, causing it to override the global ClockIn function due to legacy quirks in HTML-JavaScript interaction.

Consider renaming the form as "ClockInForm" to prevent this collision. Alternatively, you could utilize document.getElementById("...") for element referencing.
