Pick up a dice value and play on var

I’m developing a web server in PLC, in which you’ll be able to take the data from an air hose to see if the pressure is okay. I developed the code in js and set a value to see if it worked, but now I want to take the value of this pressure and if it reaches a certain number, it goes to the page in question

follows the code

$('#bot).on('
click ',function(){
})

var i = 0;

setInterval(function() {
            $('counter').text(i);
            i++;
            if (i == 6) {
                $('#pag-1).show();
                    $('pag-2).hide();
                    }
                }, 1000)

in the var i, you know what function I use to pull the data from a particular location?

javascript jquery html

  • When you say "pull the data from a given location" would it be to pull the value of an input (form field)? If yes, just use the following var i = $('#idCampo'). val();

  • this, however the values are being pulled from a program in real time, in the case of id field I would have to set a value for when the program arrived at it, identify?

  • Yes, the field in question from where it will pull would have to have an id.

  • long, thank you

If your intention is to catch the value of a input, just do the following:

jQuery(function($){
   var i = $('#numero').val(); 

   console.log(i);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

Número <input type="text" id="numero" value="5">

  • thanks Cara but where do I determine the entry of this imput? if the value will be played in real time

  • Will this value come from a PHP code? If so, you can do the following: Number <input type="text" id="number" value="<? php echo $variableComValue; ?>">

  • in reality this value is being generated in the aunt portal, within a PLC that I am making for a web server, my difficulty is just this, how to take this value of the PLC and play in an html

  • You would have to see how this PLC works to see how it works with the data and find a way to pass the value to the input in the form.

  • Leandro in the following code var i = $('#counter'). val(); Setinterval( Function () { i++; if ( i = 5000000 ) { what do you think is not rolling? I was able to play the value to the screen in real time, but now I just need to take that specific value and play an action as in this example
