tags

问题 I'm having a hard time to get to the right query/queries here. When you want to find related items using tags, in MySQL, you can use a 'common tag count' to find items that are most similar. Say my schema looks like this: tags(tag_id, title) articles(article_id, some_text) articles_tags(tag_id, article_id) Then you can get items and sort them on common tags with 'article 2' for example, like this: SELECT at1.article_id, Count(at1.tag_id) AS common_tag_count FROM articles_tags AS at1 INNER

问题 I'm having some trouble parsing an XML file in Java. The file takes the form: <root> <thing> <name>Thing1</name> <property> <name>Property1</name> </property> ... </thing> ... </root> Ultimately, I would like to convert this file into a list of Thing objects, which will have a String name (Thing1) and a list of Property objects, which will each also have a name (Property1). I've been trying to use xpaths to get this data out, but when I try to get just the name for 'thing', it gives me all of

问题 There are some formatted text inside the textarea and a cursor is in some place. I need to check if the cursor is between some specific tags. Example: foo | bar . isBetween(['b', 'strong']); // should return true in above case I have function that returns position of the cursor inside textarea (is has some IE issues, but satisfies me for now). So, all I need is that isBetween() function . Thanks for any help! Update : <p>qwer<b>ty|ui</b>op</p> isBetween(['p']); // should also return true,

问题 I'm trying to create a code button with the Froala editor which can basicly do the same thing as here on SO by pressing CNTRL+K . Now I think I have two choices. The first one is to edit the froala-editor.js file, because Froala already has a 'code' button which only adds the <pre> tags. If I could somehow get it to also add the <code> tag, problem solved. Unfortunately I didn't get this to work. The second option is to create a custom button, so far I have this piece of code: $('textarea

问题 I have used the following command to tag my HEAD with a tag named "tag": git tag -a tag -m "comment on my tag" But when I git push origin tag I get an error: fatal: tag shorthand without < tag > I don't get the same error for tag with different name.

I wouldn't like to push my other tags with git push --tags though! 回答1: If you take a look at the git code
