But the following CSS doesn't do anything to the placeholder's value: input[placeholder], [placeholder], *[placeholder] { color: red !important; } Value will still remain grey instead of red . Is there a way to change the color of the placeholder text? 回答1: Implementation There are three different implementations: pseudo-elements, pseudo-classes, and nothing. WebKit, Blink (Safari, Google Chrome, Opera 15+) and Microsoft Edge are using a pseudo

For jQuery/FCKEditor such JS could look like that: $(document).ready(function() { $("textarea").each

I am using this code to focus the caret after the current text: var oldContent = document.tweetBox.tweet.value; document.tweetBox.tweet.value = ''; document.tweetBox.tweet.focus(); document.tweetBox.tweet.value = oldContent + to; This code works flawlessly in Chrome, Fluid, Opera, Firefox en Safari. The weirdest part is that the cursor starts blinking AFTER the 'to' text if I use my hardware keyboard but the text that I enter starts where I was typing before the JS

Calling textarea.SendKeys("My text") works, but it types it in letter by letter which is obviously quite slow for longer strings.

The Keys reference they give is ambiguous between OpenQA.Selenium.Keys and System.Windows.Forms.Keys , so I tried both of them. Here's my code to do that: Clipboard.SetDataObject("My text");

And I will be happy to know how I can do this : When I type a word in a textarea, fx "google" or "facebook".

It works fine in Java 7, but for the release candidate of JavaFX 8, I can't get it to behave like before. EDIT: This question is about JavaFX TextArea, not a JTextArea. -fx-background-color: rgba(53,89,119,0.2); does not have any effect on the textarea anymore, although it should have an alpha value of 0.2, but it is opague... Is that a known issue? 回答1: The TextArea consists of several nodes. To make the background

Chunks of data are put in textareas so they can be checked, but the red underlines only appear when the user manually puts the cursor in a misspelled word. Is there a way to force WebKit to add the little red spell check underlines to textareas? 回答1: Essentially you need to use the selection api to move the insertion point over each word to get Safari to highlight it. Here's an example to scan over the first thousand
