Change textbox to textarea on click

How do I convert a simple text box to text area when the user clicks on it. I'm using EXT JS.

Are you doing it just for visual appearance? Or is there a valid reason for converting it from input to textarea?

If you are doing it just for the visuals of it you can get a long way with just setting the height of your textarea and in the focus event increase the height.

Ext.onReady(function(){

    new Ext.form.TextArea({
        renderTo: Ext.getBody(),
        name: 'myTextArea',
        width: 200,
        height: 22,
        listeners: {
            focus: function(textarea){
                textarea.setHeight(200);
            },
            blur: function(textarea){
                textarea.setHeight(22);
            }
        }
    });

});

You can even quite easily animate it for some extra fancy visualy fancy pancy. http://jsfiddle.net/chrisramakers/9FjGv/3/

Can you change a text input to textarea?, Is it possible to change a text field to a textarea while entering data and then have it revert back to a text field once the user tabs of clicks outside� Adds an event listener to a <textarea> which executes JavaScript scripting when an onchange event occurs. Code Example <form> <textarea onchange="alert('You just changed the textarea.')" placeholder="Type in this box. When you click away an alert will be generated."> </textarea> </form>

You can't change a textbox to a textarea because they are two different types of elements. You can however hide one and display the other.

<input type='text' id='myTextBox' />
<textarea id='myTextArea' />

With some function that could swap them on whatever event you want:

function swapTexts() {
    var tb = document.getElementById('myTextBox');
    var ta = document.getElementById('myTextArea');
    if (tb.style.display !== 'none') {
        tb.style.display = 'none';
        ta.style.display = '';
    } else {
        tb.style.display = '';
        ta.style.display = 'none';
    }        
}

How to Add Text to a Textarea or Text Field, How to add or replace text to a text field or textarea using JavaScript. Enter your text here, then click the button. Add to Existing Text Replace Existing Text� By default, <input> and <textarea> elements don’t change size based on the content they contain. In fact, there isn’t any simple HTML or CSS way to make them do that. Kinda funny, as that seems like a reasonable use-c

Here's an example done in jQuery.

HTML:

<tr>
    <td>
        <input name="textInputComment" type="text" value="">
        <textarea name="textAreaComment" style="display: none;"></textarea>
    </td>
</tr>

jQuery:

 $(document).ready(function()

         $(document).on('focusin', 'input[name=textInputComment]', function () {
              $(this).hide();
              textarea = $(this).closest('tr').find('textarea[name=textAreaComment]');
              textarea.show().focus().val($(this).val());//show, focus and get value from input
         });

         $(document).on('focusout', 'textarea[name=textAreaComment]', function () {
              $(this).hide();
              textarea = $(this).closest('tr').find('input[name=textInputComment]');
              textarea.show().val($(this).val());//get value from textarea
         });
  });

jQuery, This method works only on the “<input>, <textarea> and <select>” elements. Syntax : click on this button and see the change -->. Use a <form> element to add HTML forms to the web page for the user input. Add two <input> elements to define fields for the user input. With the first <input> use the type and placeholder attributes. With the second <input> besides these attributes, also use a class name.

After clicking outside of the input box: Example-2: In this example, alert box appears saying that ‘Text content changed!’ when either of activity happens. text of the input changed. keyup event happens. Something is pasted to the input box. propertychange occurs.

For radiobuttons and checkboxes, the onchange event occurs when the checked state has been changed. Tip: This event is similar to the oninput event. The difference is that the oninput event occurs immediately after the value of an element has changed, while onchange occurs when the element loses focus, after the content has been changed.
