Textarea not POSTing with form

阅读更多关于 Textarea not POSTing with form

I'm trying to input a textarea tag when I submit my form: <textarea id="confirmationText" class="text" cols="86" rows ="20" name="confirmationText" form="confirmationForm"></textarea> <form action="sendConfirmation.php" name="confirmationForm" method="post"> <input type="submit" value="Email" class="submitButton"> </form> As you can see I've set the form="confirmationForm" attribute in my textarea tag. I've used Live HTTP Headers to catch the POST request and it is empty (so I know the problem is not in sendConfirmation.php, the problem is that the confirmationText is not being POSTed). I've

How do I set textarea scroll bar to bottom as a default?

阅读更多关于 How do I set textarea scroll bar to bottom as a default?

I have a textarea that is being dynamically reloaded as user input is being sent in. It refreshes itself every couple seconds. When the amount of text in this textarea exceeds the size of the textarea, a scroll bar appears. However the scroll bar isn't really usable because if you start scrolling down, a couple seconds later the textarea refreshes and brings the scroll bar right back up to the top. I want to set the scroll bar to by default show the bottom most text. Anyone have an idea of how to do so? pretty simple, in vanilla javascript: var textarea = document.getElementById('textarea_id')

Why isn't textarea an input[type=“textarea”]?

阅读更多关于 Why isn't textarea an input[type=“textarea”]?

Why is there an element <textarea> instead of <input type="textarea"> ? Maybe this is going a bit too far back but… Also, I’d like to suggest that multiline text fields have a different type (e.g. “textarea") than single-line fields ("text"), as they really are different types of things, and imply different issues (semantics) for client-side handling. – Marc Andreessen, 11 October 1993 So that its value can easily contain quotes and <> characters and respect whitespace and newlines.

HTML5 textarea placeholder not appearing

阅读更多关于 HTML5 textarea placeholder not appearing

I cannot figure out what is wrong with my markup, but the placeholder for the text area will not appear. It seems as though it may be covered up with some blank spaces and tabs. When you focus on the text area and delete from where the cursor puts itself, then leave the text area, the proper placeholder then appears. <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> <html> <head> </head> <body> <form action="message.php" method="post" id="message_form"> <fieldset> <input type="email" name="email" id="email" title="Email address" maxlength="40"

Rails — Add a line break into a text area

阅读更多关于 Rails — Add a line break into a text area

问题 I got a rails app where I can input a few paragraphs of text into my model. The problem is I dont know how to input any line breaks. I've tried to add " {ln}{/ln} ; {&nbsp} and {br}{/br}" but that only displays the html as text and no break. Is there anyway I can set it so the text area control will use any of the html I place within the model entry? Is there any thing I can type so rails will recognize, hey put a line here? 回答1: The problem isn't so much editing the value as it is rendering
