JQuery :: Detect How Many Lines Of Text Within A Div Or A Tag?

Jun 3, 2010

Can Jquery Detect How Many Lines of Text within a Div or A tag?

I am attempting to have different backgrounds depending on how many lines the left navigation takes up. For example if the item in the left nav only takes up one line it will have backgroundA. If the item in the left nav only takes up 2 lines it will have backgroundB etc.. Currently I have everything with backgroundA but there are a few that are taking up two lines or three lines and I can't shorten them as that is what the customer needs to have, but it looks horrible...

So can Jquery detect how many lines of text within a div or a tag and follow the css so it knows when it goes to another line and it can switch the background to something longer?

Fetching Random Lines From Different Text Files

Aug 1, 2011

I'm looking for a way to have a single, random line fetched from multiple text files, and then have that combination output somewhere, whether just to some field or another text file.

For example:

Text file A -

Text file B -

Text file C -

So it would go in, get a line from each, and display something like:

I know it's a weird-sounding example, but you get the point. The line choices don't have to be separated by hyphens, but they preferably would be separated by something, like a comma, semi-colon, slash, whatever.

I know this is pretty much a web coding forum, so that would be fine if I had to host it on my server or open it with a browser. But it would be optimal if this could be made into a standalone executable.

I'm basically looking for something like Random Line Picker [url], just with the added functionality I mentioned.

I'd be willing to make a little donation to someone if coding this would be a little difficult.

Enter Text Strings On Multiple Lines.

Nov 26, 2005

When I enter a text string for a document.write method it works AS LONG AS the text is all on one line. This is true in assigning a text string to a variable also. I like to write my documents so that they are readable. How do I get the text to be on multiple lines without getting the "unterminated string" error?

Sep 30, 2009

Trying to develop a small app for my site. What is the code to generate a random # of lines (1 min - 5 max) and a random phrase for each line sourced from a multidimensional array? These also need to be unduplicated (so I won't have quote 1 be on lines 1 and 4). How do I prevent random duplication with the generated lines of text?

Jun 29, 2009

I am trying to detect the DOM element on a unkown web page from thecurrent selected text on that page.Which means: I select text on a web page and then I would like to getthe dom element to which this text belongs.What I came up with was something like that: (imagin we selected theword John on that page....)var array = $("*:contains('John')"); ---> get all domelements that contain the text 'John'But, instead of returning all dom elements that contain 'John' , itreturns only the path from the HTML element to the P element thatcontains the text 'John'. (HTML->Body->P)Did I miss something ? Is there a complete different way to accomplish

How To Detect Where Text Wraps

Oct 3, 2010

What I'm trying to do is insert hard-coded line breaks where ever the text wraps inside a div or td element (or any other element, I suppose). The point is to ensure that the text always wraps in the same place in print as it does on screen, which in turn will ensure that the container element is always the same height in print as it is on screen. It needs to work on non-monospaced type, so counting characters isn't really an option.

I've done lots of googling on this and the only thing I've found that even acknowledges that wrapped text has multiple lines is the getClientRect() method. This method returns a collection of rectangles-- one for each line of text in the container element. This can be used to determine how many lines there are, and the dimensions of each, but I don't think that really helps me, unfortunately.

Overflow Detect To Break Text Into Chunks?

Oct 5, 2010

I am trying to work out if this is possible: I have some html/text that I want to break apart into different elements (div tags), only one div tag should be visible/shown and at the bottom of the element are the number of "pages" (01/02/03/04...), each of these "pages" is actually just the next div element, the user can click on the "page number" so they can move to the next element (hidden initially) by using javascript to change which element should be displayed. Clicking on the the "page" will bring up that particular chunk of text. The div element is a specific size (width and height), and thats why only a certain amount of text can fit into it. These elements will be created dynamically from a database.

Right now I can do this by either manually forcing the user to break the text apart themselves by entering the text/html using multiple WYSIWYG editor text areas and giving them a rough amount of characters they can use and/or only allowing a certain amount of characters per textarea....Another alternative I thought of was to use php cut up the text into pieces and place them into divs by counting the number of characters based on the which font is theoretically being employed (I have a javascript script to detect if a particular font is available - how reliable it is I have yet to determine). But I was hoping that there was a solution in javascript to automatically detect when the text overflows and generate/change the number of divs, split the html/text up into the correct number of pieces and RE-generate the internal div page numbers (01/02/03/04...).

I guess there a number of problems with this idea that may stop it from being practical, such as which browser is being used, which font is being used and how the user has their text size set on their browser window... and probably other things I am not thinking of. I was hoping that by detecting if the text overflowed something could be done, but perhaps it is too complicated? Is there something out there that can do this? Is it possible? Perhaps too there are other solutions to the problem, either ones that are already out there or one that has to be built from scratch? I guess in the end my question is, is there a cleaner way of breaking the text apart in javascript by using overflow or something similar than doing it by counting characters with a server-side language?

Detect URL & Detect Something On Page & Show Content Accordingly?

Feb 14, 2009

Can Javascript be used to detect a certain url and then "not" write some html according to that url and also detect something on the page and "then" display some html?.

Example: I'm working on a volusion site that uses asp. There's basically only one page that's changed dynamically. I would like to display some html when and only if the cart has any items in it. But also not to show up on the check-out pages.

The page dynamically displays "Your cart has 1 item in it..." when the visitors puts something in their cart.

So could javascript detect when this is displayed then write some html and then also detect if the url is showing the cart and then not show the html?

JQuery :: Check Number Of Lines And Altering Other Div To Match?

May 10, 2011

Trying to check how many lines a div has and then alter another to match.

Found this code, but I'm not sure what to do [code]...

Look at Navigation and then look at Animated Menus as an example. When the grey animated menus (div.columnrt) takes up two lines (could be more), need the corresponding left div (div.columnleft) to be same number of lines, so that everything stays lined up. Each of these pairs sits inside of a li element.
