space

问题 I'm debugging a Struts Java app, in my defaultLayout.tag file there are 2 tables, there is no space between them, but in the result html which I saw from Firefox's source code Inspector, there are 2 lines of: <Br></Br> <Br></Br> I wonder where in the Struts app did it generate those 2 extra line of breaks. 回答1: In css add : br { display: none; } 来源： https://stackoverflow.com/questions/25632412/where-did-extra-space-come-from-in-html-of-struts-app

问题 I have a string like: SomeCamel WasEnteringText I have found various means of splitting up the string and inserting spaces with php str_replace but, i need it in perl. Sometimes there may be a space before the string, sometimes not. Sometimes there will be a space in the string but, sometimes not. I tried: my $camel = "SomeCamel WasEnteringText"; #or my $camel = " SomeCamel WasEntering Text"; $camel =~ s/^[A-Z]/\s[A-Z]/g; #and $camel =~ s/([\w']+)/\u$1/g; and many more combinations of =~s//g;

问题 I use Vaadin's GridLayout for visualization of some title and value labels. The GridLayout has 2 columns and several rows. Title labels are on the left side and their associated value labels on the right. I want the first column to consume as less space as possible and the second column should occupy all the remining space of the browser's window. If a value label requires more space than available then it must break the line. I tried to play with setColumnExpandRatio() . If I determine

问题 I need to write a sql query that filters out rows that have a changing number of spaces in a field. For example, I have this query SELECT MEMO_SYSTEM_TXT FROM [EE].[dbo].[EE_Billing_Memo] where MEMO_SYSTEM_TXT is not null and MEMO_SYSTEM_TXT <> '' and MEMO_SYSTEM_TXT <> ' ' I found out that the field MEMO_SYSTEM_TXT might contain different number of spaces, so my restrictions are not sufficient. Anyone have a robust where cluase that will filter out all spaces at once ? 回答1: SELECT MEMO

问题 First of all, I do apologize I don't put my link here, it's a site for work and I'm not allowed. I'll post the relevant parts of my code if necessary though. So the problem is pretty basic - i have one div with some images, and a header <h3> below where my content starts . No matter how much I try to create some space between the two, it doesn't work. I've tried margin and padding on both elements, changing between position relative and absolute, and throwing in lots of <br> tags. Nothing

Here is my layout xml file: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="wrap_content" android:orientation="horizontal" android:background="#fa9654" android:paddingTop="65dp" android

问题 I need to know true tablespace size in Oracle. I have some tablespace and I need to know how many space it uses now and how many space is free (and maybe percent of free space). I found in web some sqls but all of them showed size based on water mark... which is not true space allocated now but as far as I know the highest value which has ever been reached... So my real need is to know if I have enough space for my data which constantly are written and I must know how much of them I can store

问题 I'm programming a game in android where an enemy ship needs to fire in a star pattern around itself. Basically, for any X number of shots I set the enemy ship to fire, I want it to divide 360 degrees around itself by the number of shots and fire the shots off at exactly equilateral angles. So, 3 shots would be fired off with the first shot at 360 degrees, the second shot at 120 degrees and the third shot at 240 degrees. 4 shots would be 360,90,180,270 and so on. Then each shot will travel

问题 how can i search "ice cube" if I have "icecube" in my index. I have set mm as 2<-1 4<70%. While using shingle in query analyzer, the query "ice cube" creates three tokens as "ice","cube", "icecube". But mm is the limitation here.
