paragraph

问题 Is it possible to detect if the content of a paragraph has been changed in JQuery ? I tried the below code. <p id="test">Text</p> <button id="submit1">change</button> - $(document).on("click", "#submit1", function () { var d = new Date(); var time = d.getHours() + ":" + d.getMinutes() + ":" + d.getSeconds(); $("#test").text(time); }); $(document).on("change", "#test", function () { alert("Paragraph changed"); }); JSFiddle : http://jsfiddle.net/nnbqye55/ I guess I am missing something obvious.

问题 I want to display written textarea text in another textarea by clicking a third element. So here's the code I'm using at the moment but it shows the written text when you press the textarea : $(function(){ $('#text').click(function(){ $('#preview').text($(this).val()); }); }); And here's the HTML part: <textarea id="text"></textarea> <textarea id="preview"></textarea> <div id="show-text"></div> So the idea is to display the text inside textarea#text in textarea#preview when you click div#show

问题 For example, if I have the following lines of text in a file: this is an example. this is an example. this is an example. this is an example. this is an example this is an example this is an example this is an example this is an example this is an example this is an example this is an example this is an example this is an example this is an example. I want to be able to count these lines as 3 paragraphs. Now my code will count this as 4 paragraphs, as it does not know when a paragraph begins

问题 So I have been working on my first website, and I'm having lots of fun doing it. However, I have found it very difficult to achieve centering a paragraph (spanning more than one line) vertically and horizontally inside of it's div container. The div has a proportional width (96%), and it is not set by pixels. Also, the paragraph has a set amount of padding (ex: 20px top and bottom). Is there a trick to center vertically and horizontally in this situation? Thanks a bunch! 回答1: See this fiddle

问题 Is there a convenient way to format a rather long string with paragraphs in it (like below) to have it with \n in it so the textView will display the paragraphs as well? blah blah to @"blah\n\nblah" Thanks! 回答1: Here's a simple example assuming you have : A file named : myfile.txt A string variable to hold the file's content, let's name it : content A UITextView called :textView Write whatever you want in your text file and place it wherever you want in your Xcode project (usually import it

问题 How would I take a Paragraph object and databind them to the TextBlock for use in a DataTemplate? A plain bind does nothing, just a ToString() of the Paragraph object. The InLines property would let me add a list of TextRun's that make up the Paragraph manually, but that can't be bound to and I could really do with a binding based solution. Edited question to focus on what I really need to do. 回答1: Here's an example using a nested ItemsControl. Unfortunately, it will make one TextBlock per

问题 I have made some code and css, now I'm learning to understand them.. What is the difference if I use margin or padding? What is recommended to use on my <p> tag? I'm using margin now, but margin is for the outside of an element, why whould I use that if padding is for the space between the content and border. So let's start what I have: <div id="MainContainer"> <section> <article> <h1>Title</h1> <p> text text text text text </p> </article> </section> </div> My CSS looks like this

问题 I'm working on a site that uses a responsive layout and I've run into a problem getting around the shortcomings of the newer CSS multi-column properties (http://dev.w3.org/csswg/css3-multicol/). When the browser window is wide enough, I split the text into two columns with an sidebar for smaller images. The multi-column css properties work great, but they're not too smart. The first section is split evenly into two equal-height columns, but they're way too tall. For someone to read this
