Get a value of span tag HTML

my span tag looks like this:

<span id="quantity_value" value="1">1</span>

And the value changes by using jquery.

I want to have value of this span as a parameter, when i try with js script:

var number = document.getElementById("quantity_value");

My number is equal to:

'<span id="quantity_value" value="1">1</span>'

But I want number to be equal to value.

With jquery you can say $('#quantity_value').val() to get the value of the span.. The first part is the selector which selects your span element. The .val() is a method to get the value of the attribute value.

var number = document.getElementById("quantity_value").textContent (vanilla JS) or var number = document.getElementById("quantity_value").text(); (jQuery)

Actually since it's a span, having a value doesn't make sense here. Spans are not input elements.

wait, what exactly the OP wanted? The text content inside element, or the value attribute of span?

Use

var number = document.getElementById("quantity_value").innerHTML;

By writing only

var number = document.getElementById("quantity_value");

you store object in variable.

I would suggest changing value to a data field to fix your non-standards compliant html, and then you can retrieve that attribute when you need the value. For instance:

$('#changeValue').on('click', function(){

  var newValue = Date.now() % 100;

  

                                   //change the data attribute

  $('#quantity_value').text(newValue).data('value', newValue);

});



$('#getValue').on('click', function(){

  console.log($('#quantity_value').data('value'));

});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

<span id="quantity_value" data-value="1">1</span>

<div><button id="changeValue">Change Value</button></div>

<div><button id="getValue">Get Value</button></div>
