The .val() of a textarea doesn't take new lines into account

由 ε祈祈猫儿з 提交于 2019-11-27 08:40:54
The .val() property of an item in jQuery for a <textarea> doesn't seem to work with new lines. I need this function as the text-area is meant to recognize the enter key and display it as a preview, with the new line in tact. However, what happens is shown in this fiddle: http://jsfiddle.net/GbjTy/1/ . The text is displayed, but not in a new line. How can I achieve the preview to include new lines, and I know it is possible, because it does this in the Stack Overflow Post Question preview. Thanks. P.S I have seen other links on SO relating to this, but they all say get the End User to use some

Find out the 'line' (row) number of the cursor in a textarea

由 筅森魡賤 提交于 2019-11-27 08:38:25
I would like to find out and keep track of the 'line number' (rows) of the cursor in a textarea. (The 'bigger picture' is to parse the text on the line every time a new line is created/modified/selected, if of course the text was not pasted in. This saves parsing the whole text un-necessarily at set intervals.) There are a couple of posts on StackOverflow however none of them specifically answer my question, most questions are for cursor position in pixels or displaying lines numbers besides the textarea. My attempt is below, it works fine when starting at line 1 and not leaving the textarea.

How can I limit the length of <h:inputTextarea> ? For <h:inputText> it works fine with maxlength attribute. However, this attribute is unavailable in <h:inputTextarea> .

Finding number of lines in an html textarea

由 时光总嘲笑我的痴心妄想 提交于 2019-11-27 07:51:14
I'm writing a mobile web application where scrollbars are not displayed on the device's browser. Due to this, I'm trying to dynamically modify the height of the textarea to make it bigger, however I don't know of any way to actually get the line count on an html textarea. Any help would be greatly appreciated! EDIT So I realize now that it's not newlines per se, but actual line wrapping. So when one line finishes it wraps the text to the next line. It appears as if it is a new line. Any way to count the number of these? Thanks! I haven't tried using the function discussed in this blog, but you

HTML Textarea horizontal scroll

由 眉间皱痕 提交于 2019-11-27 07:02:26
I would like to provide a horizontal scroll to a textarea in my HTML page. The scroll should appear without wrapping, if I type a long line without a line break. A few friends suggested using overflow-y CSS attribute, which did not work for me. The browsers that I use are IE 6+ and Mozilla 3+. Aram Kocharyan To set no wrapping, you would use: white-space: nowrap; For other values: https://developer.mozilla.org/en-US/docs/Web/CSS/white-space NOTE: However the depreciated wrap="off" seems to be the only way for legacy browser support. Though it isn't HTML 5 compliant, it's still my preference if

Ckeditor update textarea

由 喜欢而已 提交于 2019-11-27 06:53:25
I am trying to get the ckeditor working. Obviously it doesn't make use of the textarea so on submit the form doesn't submit the text in the editor. Beceause I make use of polymorphic associations etc. I can't make a onsubmit function to get the value of the textarea (when the form is submitted) . So I found this question: Using jQuery to grab the content from CKEditor's iframe with some very good answers. The answers posted there keep the textarea up to date. That is very nice and just what I need! Unfortunately I can't get it to work. Does somebody know why (for example) this doesn't work? I
