How do you compare the current significance of the change to the previous one?



  • There's a variable. vlll That's what you get from the input. How do we make sure, for example, the first time in the input verification, for example, by clicking, it keeps the value, and in the second check, it compares the first value to the second one, and if it doesn't matter what it's?

    I'm asking you this way:

    var vlll = $("#scanInput").val();
    


  • You can add a data-storage parameter, for example. And it's gonna be data-storage=100." And compare to the values in this parameter.
