textarea

I am trying (and failing) to implement a drag&drop mechanism into an HTML textarea. Drag&Drop mechanism is relatively easy with jQuery or Scriptaculous (we use both), so I am willing to accept an answer that uses either of these two. Problem is, I cannot seem to find a way to read or set the insertion point. What I ultimately want to be able to do is determine the drop location, do some kind of mathematical calculation to determine where on the textarea that is exactly, then set the caret position (or insertion point), and place (insert) dropped text there. I can handle the calculations, I

I have this HTML code: <form class="_b6i0l"><textarea aria-label="Add a comment…" placeholder="Add a comment…" class="_bilrf" autocomplete="off" autocorrect="off" style="height: 18px;"></textarea> <textarea aria-label="Add a comment…" placeholder="Add a comment…" class="_bilrf" autocomplete="off" autocorrect="off" style="height: 18px;"></textarea> </form> I want write a text in the filed. But, this error is happened: selenium.common.exceptions.ElementNotInteractableException: Message: Element <textarea class="_bilrf"> is not reachable by keyboard My code which sends the text is: add_comment

I am using a few page validation tools one problem i have is they tell me textarea must have rows and cols attribute. If i am setting this in CSS or using display:none (and using it to hold raw text data) can i do something to skip? it seems like the only answer is rows="0" cols="0" each time i use it. But i have a feeling that is not a good solution. Stop using a textarea . If you want something to hold raw data, then use a <script> element (if you plan to access it with JS) or an input of type hidden (if you plan to submit it as form data). Don't use semantics that say "Let the user enter

I want to display the array content after it.

Is it possible to detect what text has been selected in a text area using Javascript? I'm looking to show the user controls only when they have selected text Tim Down I've written a cross-browser function for getting the text selected in a textarea or text input and after some toing and froing the final version is I think the best one I've seen. I've posted it on Stack Overflow a few times before. Here's one example: Is there an Internet Explorer approved substitute for selectionStart and selectionEnd? To detect when the user makes a selection in a textarea, you can use the select event: var

I'm trying to make a TextArea have a default value. <%: Html.TextAreaFor(Function(model) model.Description, 5, 10, New With {.Value = "Description: "})%> This works properly in a TextBoxFor but doesn't work in a TextAreaFor Am I missing something very obvious? You can specify the value for Description property in the controller action when creating the model, and pass that model to the View: public ViewResult Create() { var model = new MyPageModel() { Description = "Description: "; } return View(model); } In the view: <%: Html.TextAreaFor(model.Description) %> Setting the value won't work as
