line-breaks

问题 I have a UILabel which is populated from the database .. the text in the UILabel can be long and can be short .. the problem is that the text is being cut at the end .. for example its shown like this: "www.sample.com/h1/h2/h3..." where it should be: "www.sample.com/h1/h2/h3/h4/h5/h6.html" This is the code I am using: CGFloat constraintWidth = 180.0f; CGSize labelsize = [details.web sizeWithFont:self.webTextLabel.font constrainedToSize:CGSizeMake(constraintWidth, CGFLOAT_MAX) lineBreakMode

问题 Does HTML support any kind of hinting for (title) line-breaks? The problem is that often page titles or navigational titles have funny line breaking, as they happen to break wherever the current HTML element spacing allows. Manual line-breaks would give much nicer visuals, when line-breaks are needed. The line-break hints should be something the editor can himself/herself enter to an <input type=text> field. 回答1: There's the ­ (soft hyphen) entity and the <wbr> tag (HTML5) for word break

问题 How do I check if the cursor is on an empty line inside a textarea? I don't care about word wrapping. I care about lines that were created by hitting Enter . $('textarea').on("change keyup", function() { if (cursor is on an empty line or the the line has just spaces) { console.log("empty"); } else { console.log("has stuff"); } }); For example: This would log "has stuff" The line above would log "empty" and this line would log "has stuff" 回答1: The following should work, but won't in older

问题 How can I apply manual line breaks in Hint.css hints? I tried almost everything: <br>, \n, and combinations of them. I tried also some things in the CSS: white-space: normal; word-wrap: break-word; word-wrap: no-wrap; word-wrap:break-word white-space: nowrap; Now : Without line break, the hint is one line high, but and any length long. Ideally : Apply a manual line break wherever I want, leaving the untouched hints without line breaks. 回答1: Found the answer at: https://github.com/chinchang

问题 I count number of rows (lines) in a file using Python in the following method: n = 0 for line in file('input.txt'): n += 1 print n I run this script under Windows. Then I count the number of rows in the same file using Unix command: wc -l input.txt Counting with Unix command gives a significantly larger number of rows. So, my question is: Why Python does not see all the rows in the file? Or is it a question of definition? 回答1: You most likely have a file with one or more DOS EOF (CTRL-Z)

问题 I have different sentences which all have double quotes in them, like: <h3 class="myClass">Sentence one "ends like this"</h3> <h3 class="myClass">Sentence two"ends like that"</h3> <h3 class="myClass">Sentence three "another ending"</h3> All on a page. Basically all values are differents, and I'm trying to have a line break just before the double quote so it would be like <h3 class="myClass">Sentence one <br/>"ends like this"</h3> <h3 class="myClass">Sentence two <br/>"ends like that"</h3> <h3

问题 I'm working on a text input for the backend of a website. I want a couple things to be automatically corrected. Example, new lines in the textarea I convert to <br> . I also want to let the user tab over on new lines. This requires changing spaces over to   . I only want to convert spaces that are at the start of a new line though. Example, say the user types this into a textarea: This is my text! It's pretty great. This is a second line. This is a third line, that is indented by four spaces.

问题 I need to use a break-line in a AlertDialog on Android. I already tried with the "\n" character but it doesn't work. I don't see the "\n" character but the text wont wrap. Any help? 回答1: You can use Spanned text using Html.fromHtml("some string" + "<br>") to create new line on some textview element. 回答2: If you are receiving the String from somewhere, maybe the \n is being escaped. Try with: string = string.replace("\\n","\n"); 回答3: How about using the HTML tag to set new text? controlName
