In the following snippet I try to pass an input value to an array and then to print it to an excisting paragraph.The strange thing is that the value is printed to the paragraph for a second and then it returns to the previous status.

<html>
   <head>
     <title>forms-javascript</title>
	</head>


    <body>
    <p id="prgrph">form-test</p>
    <form id="frm">
	   <label for="input2">Town:</label>
	  <input type="text" name="npt" id="input2" required>
	  <button  id="btn">Submit</button>
	</form>

    <script>
      let myArray=[];      
	  document.querySelector("#btn").addEventListener("click",function(e){
	  e.preventDefault;
	  myArray.push(document.querySelector("#input2").value);
	  document.querySelector("#prgrph").innerText=myArray[0];
	  });
	  
	 </script>
    </body>
    </html>

Thank you in advance!

Solution 1

Try to use the next snippet in the button (click event)

var yourArr = $('#input2').map(function() {
    return $(this).val();
}).get();

the above code will get the "input2" value and append it in an array named (yourArr)

hope it helps
