textarea

问题 How do I put initial text into a Spring form textarea? The TLD rejects PCData content inside form:textarea. The point of this form is to ask a user to edit/correct some text, so the text has to get into the form in the first place. The JSP page is pulling the text from the model and wants to put it into the textarea. 回答1: You could set the initial value with Javascript. You could use tags to control when you need to set the message in the textbox so the script code will be rendered or not.

问题 I am trying to set a maxlength for the form_textarea() in Codeigniter. I tried the following: <?php $options = array( 'maxlength' => '100' ); ?> <tr> <td><?= form_label('Profiel:');?></td> <td><?= form_textarea('Profiel', $options, $info['Profiel']);?></td> </tr> When I edit my form to edit the text in the textarea it says Array. So the text is gone and is replaced with Array. But that is not working. Maybe I have to use Jquery? 回答1: Codeigniter allows you to pass attributes into your form

问题 I want to show a text area based on a button click. Pretty simple, but the textarea and button are dynamically generated using Knockout js. My current code works, except it only expands the first text area. There are several projects displayed. HTML (the button and textarea are the last two controls): <!-- ko foreach: projects --> <div id="eachOppyProject" style="border-bottom: 1px solid #eee;"> <table> <tbody> <tr> <td><a data-bind="attr: { href: '/tools/oppy/' + guid }" style="font-size:

问题 I'm working on a BBcode editor, and was wondering how to toggle tags on selection using Javascript (similar to how the text editing menu works on StackOverflow). Example: Textarea Lorem ipsum dolor sit amet. If you select the text 'ipsum dolor' and click on the bold button, it'll become Lorem [b]ipsum dolor[/b] sit amet. If you click the bold button once again, it'll remove the tags. Thanks! 回答1: You can get the selected text caret positions, set the caret and then insert your text: TL;DS

问题 This is related to my previous Flex issue: Flex TextArea - copy/paste from Word - Invalid unicode characters on xml parsing But this is slightly different & seems to be the issue. So I had to create another thread for this. When I copy/paste text from word to a text area, I do not see any invalid characters. But when I pasted the same text on this url: http://blog.flexexamples.com/2008/03/07/preventing-line-feeds-in-a-textarea-control-in-flex/ I'm seeing a little square " ". Please paste this

问题 I've already seen this post: Changing the size of Html.TextBox But I cannot change to Html.TextAreaFor() because it does not have an attribute for me to set a dynamic default value (I am making an edit page that I want to dynamically fill in the fields of the current data which can then be modified). I also can't seem to get the EditorFor to work even if I change to [DataType(DataType.MultilineText)] in my viewmodel (all it does it seem to change to textboxfor and my default values do not

问题 I've got an application where users can store snippets of HTML and ASP code in a database. The trouble is, when i dynamically populate the textarea control, all the various characters that can be in an HTML snippet will cause the page to not render properly. Can someone point me to a guideline/how-to on stripping out / replacing various characters before outputting to the browser? Do I strip out the angle brackets and replace with a stand-in character? Do i force my users to enter < and >

问题 I am using Ace Editor to build a code replay program. I store all the keys pressed when you type code, and then I replay them in Ace Editor. I have finished storing and replaying all keyboard/mouse input, but am having issues replaying tab presses. Ace Editor handles tabs within a textarea DOM. The default behavior for a textarea when tab is pressed is to move to the next DOM, so I know they are using preventDefault() and using their own handler in order to allow softTab (insertion of 1,2,3,
