问题 using value.length != 0 ..doesn't work for the blank space situation 回答1: Try jquery and use its trim() feature. If someone is inputting spaces, value will be neither null nor length == 0 . 回答2: Try this: if (value.match (/\S/)) { ... } It will make sure value has at least 1 non-whitespace character 回答3: document.myForm.myField.value != ""; // or document.myForm.myField.value.length == 0; Example: function isEmpty() { alert(document.myForm.myField.value == ""); } -- <button onclick="isEmpty()

To include this easily with Wicket, I suggest the org.wicketstuff.tinymce-parent package. The development/source code is in GitHub and the actual releases are in the public maven repository. You can then use a standard Wicket

问题 I get a textarea with a keyup function attached. When the user type something, I want this text to be rendered inside the blockquote tag. It works, but id doesn't take the newline and spaces.

Textarea doesn't show newline in IE

UPDATE: Seems like it's asp.net that is rendering asp:TextArea differently for different browsers - for
