Can you provide more information about what exactly it is that you need help with? The title of your post is related to previewing. If all you need is to preview something that is within a textbox, you can do so with JavaScript. how do you want it to be previewed (by clicking, onkeypress)?

Post your relevant code, describe the issue you are having to help solve your problem.

yes jorgem you got my point.i want to create a textarea and a button by which i can make the selected text bold.

Do you have any HTML code written yet? I think this can be easily done via JavaScript.

My thought is display a textarea element, a button, and then a div for the preview.

Call a function when you click on a button, and in the function use the values of the selectionStart and selectionEnd properties of the textarea and assign that to a string. Then take the string and wrap that string with <b> tags for bold, display it in the preview div...

I don't think you can directly show the bold effect in the textarea. As JorgeM mentioned, you should manipulate the content in a seperate div tag or paragraph in order to display the change. So you should have another button called preview textarea.

Here is a quick demo I put together based on the concept i explained above. added buttons for bold, italics, and underline.
