change inputtype for inputfield from string to int in javascript in javascript

To change the input type for an input field from a string to an integer in JavaScript, you can make use of the parseInt() function. This function takes in a string as its parameter and returns an integer.

Here's an example of how you can change the input type of an input field with an ID of myInput:

<input type="text" id="myInput" value="10">
<button onclick="convertToInt()">Convert to Integer</button>

<script>
  function convertToInt() {
    var inputField = document.getElementById("myInput");
    var inputValue = inputField.value;

    // use parseInt() to convert input value to integer
    var intValue = parseInt(inputValue);

    inputField.type = "number"; // change input type to "number"
    inputField.value = intValue; // set input value to converted integer
  }
</script>
490 chars
16 lines

In this example, we retrieve the input field element using document.getElementById(), get its current value using the .value property, and then use parseInt() to convert the value to an integer.

Next, we change the type attribute value of the input field to "number", indicating to the browser that the input value must be an integer. Finally, we set the input value attribute to our converted integer value using the intValue variable.
