How can I replace whole input field with its value in JavaScript or jQuery?

-2

Say, I have an html input field.

  <input type='text' class='txtData' />

In documentready method I set value of that input field.

  $(".txtData").val(2);

Now I convert this html input field into string like below.

  var sText = "<input type='text' class='txtData' />";

Now I want to replace this sText with $(.txtData).val().

How can I solve this? I google a lot but not find any solution

I find below solution which replace whole sText to " ".

  sText.replace(/<input[^>]*>|</input>/gi, "");

But how can I replace it with selected input field's value?

Thanks in advance.

sText contains a string. So you cannot treat it as if it were a DOM Element. In other words, the string referred to by sText does not have a value property.

sText = "" + $('.txtData').val() + "" and append it in place of the text box?

You can parse string to html using JQuery.parseHTML and then use the variable to update value.

example:

<!DOCTYPE html>

<html>

<head>

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

<script>

$(document).ready(function(){

    $("button").click(function(){

         var sText = "<input type='text' value='21' class='txtData' />";

         var html = $.parseHTML(sText);

          //alert('before update '+$(html).val())

          console.log('before update '+$(html).val());

         $(html).val(19);

          //alert('after update '+$(html).val())

           console.log('after update '+$(html).val());



    });

});

</script>



</head>
