  • jQuery filter selector, is this right?

    - by fire
    It seems to work ok but I don't know if this can be impoved on or not. I want to select any HTML tag that has a class of edit-text-NUM or edit-html-NUM and change the color of it. Here is what I am using... jQuery(document).ready(function(){ jQuery('*') .filter(function() { return this.className.match(/edit-(text|html)-\d/); }) .css({ 'color': '#ff0000' }); }); Does that look ok and is the regex ok? *edit: Also is this efficient? I am aware that using jQuery('*') might be a bit of a hog if it's a large page. It only has to work from <body> down so maybe it could be changed?

  • limiting a query to a specific item

    - by Dev-Ria
    I have a db with thousands of domains and data. I want to list only 100 rows of each domain. i can't use LIMIT 100 cause that only limits 100 records but I want dom1 to list 100 dom2 to list 100 dom3 to list 100 all in one query. This is what I have so far. SELECT domain COUNT(Key) AS DomCount FROM table_domain GROUP BY user,location ORDER BY domain,DomCount DESC Could I use a CASE?

  • Database Design Question

    - by Soo
    Ok SO, I have a user table and want to define groups of users together. The best solution I have for this is to create three database tables as follows: UserTable user_id user_name UserGroupLink group_id member_id GroupInfo group_id group_name This method keeps the member and group information separate. This is just my way of thinking. Is there a better way to do this? Also, what is a good naming convention for tables that link two other tables?

  • bulk insert from Java into Oracle

    - by Will Glass
    I need to insert many small rows rapidly into Oracle. (5 fields). With MySQL, I break the inserts into groups of 100, then use one insert statement for every group of 100 inserts. But with Oracle, user feedback is that the mass inserts (anywhere from 1000-30000) are too slow. Is there a similar trick I can use to speed up the programmatic inserts from Java into Oracle?

  • Makefile: couple syntax questions

    - by Michael
    package_version := $(version)x0d$(date) what is the x0d part between version and date vars? is it just string? What $(dotin_files:.in=) does below code dotin_files := $(shell find . -type f -name \*.in) dotin_files := $(dotin_files:.in=) what this means $(dotin_files:=.in) code $(dotin_files): $(dotin_files:=.in) $(substitute) [email protected] > $@ can target contain multiple files? what is the meaning of declaring target variable as PHONY? code .PHONY: $(dotin_files) In the regex replacement code below code substitute := perl -p -e 's/@([^@]+)@/defined $$ENV{$$1} ? $$ENV{$$1} : $$&/ge' what are $$ENV{$$1} and $$&? I guess it's Perl scope... thanks for your time

  • Why fork() before setsid()

    - by corentin.kerisit
    Why fork() before setsid() to daemonize a process ? Basically, if I want to detach a process from its controlling terminal and make it a process group leader : I use setsid(). Doing this without forking before doesn't work. Why ? Thanks :)

  • Read external HTML page and then find data within

    - by inthewayboy
    I'm playing around with an idea, and I'm stuck at this one part. I want to read an external HTML page and then extract the data held within two <dd> tags. I've been using file_get_contents with good results, but I'm at a loss as to how to accomplish that last part. The two tags I want to extract the value from are always enclosed within a particular <div>, was wondering if that might help? In my mind it reads the entire html file into a string, then dumps all the data up until this one particular <div>, and dumps all the data after the closing </div>. Is that possible? I think this needs regex syntax which I've never used yet. So any tips, links, or examples would be great! I can provide more info as necessary.

  • Get groups of 4 elements from name value list using LINQ in C#

    - by Kodefoo
    I am wanting to loop through this list of name value pairs and grab them in groups of 4. The data would be like: value1 1 value2 1 value3 1 value4 1 value1 2 value2 2 value3 2 value4 2 and it would group it as 1 list that contains value1 1 value2 1 value3 1 value4 1 and another list that contains value1 2 value2 2 value3 2 value4 2 I know this can be done easily with a for loop, but I am wondering if there is a good way to do it with LINQ.

  • Generic solution to deselect buttons in java

    - by Hectoret
    In a set of radio buttons of the same group, only one can be selected at the same time. I would like to have the same behaviour with a normal button. Imagine there's a row of 3 buttons. When a button is selected it changes: but.setSelected(true) and the other two buttons should be NOT selected: but.setSelected(false) Now, is there a generic, simple and clean solution to accomplish that in Java (Swing) ?

  • Getting specific data from database

    - by ifsession
    I have a table called Categorie with a few columns and I'm trying to get only a few out of my database. So I've tried this: $sql = 'SELECT uppercat AS id, COUNT(uppercat) AS uppercat FROM categorie GROUP BY uppercat;'; $d = Yii::app()->db->createCommand($sql)->query(); But I find the output strange. I was trying to do an array_shift but I get an error that this isn't an array. When I do a var_dump on $d: object(CDbDataReader)[38] private '_statement' => object(PDOStatement)[37] public 'queryString' => string 'SELECT uppercat AS id, COUNT(uppercat) AS uppercat FROM categorie GROUP BY uppercat;' (length=100) private '_closed' => boolean false private '_row' => null private '_index' => int -1 private '_e' (CComponent) => null private '_m' (CComponent) => null Ok.. then I did a foreach on $d: array 'id' => string '0' (length=1) 'uppercat' => string '6' (length=1) array 'id' => string '3' (length=1) 'uppercat' => string '2' (length=1) array 'id' => string '6' (length=1) 'uppercat' => string '1' (length=1) array 'id' => string '7' (length=1) 'uppercat' => string '2' (length=1) array 'id' => string '9' (length=1) 'uppercat' => string '2' (length=1) Then why do I get the message that $d isn't an array while it contains arrays? Is there any other way on how to get some specific data out of my database and that I can then do an array_shift on them? I've also tried doing this with findAllBySql but then I can't reach my attribute for COUNT(uppercat) which is not in my model. I guess I'd have to add it to my model but I wouldn't like that because I need it just once.

  • cron library for java

    - by nutsiepully
    I am looking for a cron expression library in java. Something that can parse cron expressions and return me future fire times for the trigger. API on the lines of. CronExpression cronExpression = new CronExpression("0 30 4 * * *"); List<Date> fireTimes = cronExpression.getFireTimes(todaysDate, nextWeekDate); I don't want to use something as complicated as quartz. The purpose is to basically use cron like a regex for timings. That's all. I do not want a background scheduler. I tried googling but wasn't able to find anything very helpful. Any suggestions would be appreciated. Regards, Pulkit P.S - I looked at using the CronExpression class out of quartz. Wasn't very helpful - failing some tests.

  • How can I dynamically resize the jQuery Colorbox plugin?

    - by James Skidmore
    The AJAX content loaded in a Colorbox has some JavaScript included that resizes things within the content. Colorbox determines its sizing based on the sizes before all of the AJAX happens. How can I make the Colorbox resize after the content has been loaded? Here is a link where someone said that you can call colorbox() again after it's been loaded, but I can't figure out how to do that: http://groups.google.com/group/colorbox/browse_thread/thread/535d21c69e9006b0
