Possible Duplicate: Why would a javascript variable start with a dollar sign? What's the difference between ‘var $x’ and ‘var x’ in jQuery? ...
This is sort of a meta-question. Many snippets of JavaScript I've seen here on SO are named with a dollar sign prefix (for example, $id on the second line of the snippet shown in this question). I'm not referring to jQuery or other libraries. I am well aware that this is valid, but it seems awkward to do when not necessary. Why do pe...

Hello, I want to know how to echo a string that have a $ sign from a database. At this time, the value on database 'Buy one for $5.00' converts to 'Buy one for .00'.

I'm trying to get some pre-existing MooTools code to function properly within a Drupal site. I know the MooTools code works on its own. Once I load the MooTools library in the page, jQuery stops functioning. I am including MooTools after jQuery, which (according to the MooTools developers) should prevent Moo from stealing the already de...
I'm having trouble getting regular expressions with leading / trailing $'s to match in Java (1.6.20). From this code: System.out.println( "$40".matches("\\b\\Q$40\\E\\b") ); System.out.println( "$40".matches(".*\\Q$40\\E.*") ); System.out.println( "$40".matches("\\Q$40\\E") ); System.out.println( " ------ " ); System.out.println( "40$"...
So I have an element I want to modify (with Fx.Tween, but I suppose it doesn't really matter). However, the element id is dynamically generated, meaning I have to piece it together from some variables. So let's say... (in js) name = 'foo'; id = '42'; and I want to access element $('foo_42')... how would I type it out? $(name+'_'+id)...

Is there some reason why a PHP interpreter needs such a sign, when interpreters/compilers for other languages are capable of...
Hi. I am aware to output dollar signs you escape it with \ such that: \$ % prints '$' However, I can't print something like \$ JAVA_HOME % prints '$ JAVA_HOME' The space in between the $ and JAVA_HOME is what's annoying. How can I make it so it's one word? ...
If I have a variable containing an unescaped dollar sign, is there any way I can echo the entire contents of the variable? For example something calls a script: ./script.sh "test1$test2" and then if I want to use the parameter it gets "truncated" like so: echo ${1} test1 Of course single-quoting the varaible name doesn't help. I ca...
