dollar-sign

问题 I am trying to put some asm code into a latex document, onfurtunatly pdflatex treats the $ signs within my document as math env (which I do not want). On the other side I'd still like to use that fancy linebreak arrow (which uses math env to display it). \lstset{ texcl=false, mathescape=false, .., prebreak = \raisebox{0ex}[0ex][0ex]{ensuremath{\hookleftarrow}} } example snap: CTRL_WD_12 equ $303400 CTRL_WD_34 equ $220000 CTRL_WD_56 equ $000000 CTRL_WD_78 equ $000000 thanks for any help. 回答1:

问题 I'm currently reading 'Javascript Web Applications' (O'Reilly, Alex MacCaw) and very early on there's a code snippet which might appear to execute a JS function, within an HTML document, yet it is not enclosed by <script> tags: // template.html <div> <script> function doSomething(aParam) { /* do stuff ... */ }; </script> ${ doSomething(this.someX) } </div> Please could someone kindly explain the dollar-sign-curly-brace notation ? I'm currently learning JS and I haven't seen this before, so I

问题 Given the following bar chart: import numpy as np import matplotlib.pyplot as plt import pandas as pd df = pd.DataFrame({'A': ['A', 'B'], 'B': [1000,2000]}) fig, ax = plt.subplots(1, 1, figsize=(2, 2)) df.plot(kind='bar', x='A', y='B', align='center', width=.5, edgecolor='none', color='grey', ax=ax) plt.xticks(rotation=25) plt.show() I'd like to display the y-tick labels as thousands of dollars like this: $2,000 I know I can use this to add a dollar sign: import matplotlib.ticker as mtick fmt

问题 I'm working with a developer that never uses var when declaring variables in jQuery. Something like: $x = "hello"; $y = "world"; $a = x + " " + y; jQuery doesn't have a problem with this and he's been doing this for awhile. I've always used var: var x = "hello"; var y = "world"; var a = x + " " + y; We have run into one issue where the dollar sign caused an issue (it was a year ago so I can't recall the issue). Does anyone know or have info on the difference between the two and why one is

问题 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 defined $ from the already loaded jQuery library. I've converted all references of $ within my Moo code to document.id. When I load the page, the Moo code works

问题 Given the following data frame: import pandas as pd df=pd.DataFrame({'A':['$0-$20','$20+']}) df A 0 0−20 1 $20+ I'd like to create a bar chart in MatPlotLib but I can't seem to get the dollar signs to show up correctly. Here's what I have: import matplotlib.pyplot as plt import numpy as np y=df.B x=df.A ind=np.arange(len(x)) fig, ax = plt.subplots(1, 1, figsize = (2,2)) plt.bar(ind, y, align='center', width=.5, edgecolor='none', color='grey') ax.patch.set_facecolor('none') ax.patch.set_alpha

问题 This question already has answers here : What does $ mean/do in Haskell? (2 answers) Closed 5 years ago . This happens in the situation you want to apply bunch of functions to the same variable, it may look like this: map (\f->f 4) [odd, even] but from LYAH using $ make it very neat map ($ 4) [odd, even] why does it work. first I type it in ghci like $ 4 odd , it failed, then I type ($ 4) odd , which works fine. then I check the type of ($ 4) using :t which shows ($ 4) :: Num a => (a -> b) ->

问题 I have a search string. When it contains a dollar symbol, I want to capture all characters thereafter, but not include the dot, or a subsequent dollar symbol.. The latter would constitute a subsequent match. So for either of these search strings...: "/bla/$V_N.$XYZ.bla"; "/bla/$V_N.$XYZ; I would want to return: V_N XYZ If the search string contains percent symbols, I also want to return what's between the pair of % symbols. The following regex seems do the trick for that. "%([^%]*?)%";

问题 Can I use the following in C++ ?: #define $ cout int main(){ $<<"Hello World!\n"; return 0; } I'm wondering whether it will cause any conflicts. 回答1: It's not definitively legal , but your implementation is allowed to accept it. Consider: [C++11: 2.5/1]: Each preprocessing token that is converted to a token (2.7) shall have the lexical form of a keyword, an identifier, a literal, an operator, or a punctuator. Here, your $ is obviously not a keyword, operator or punctuator (as these are

问题 I'm a bit confused regarding the dollar sign in jQuery, and was hoping someone could help me out. I have the following function declaration: $(function() { $( "#create-discussion" ).button().click(function() { alert("Clicked"); }); $( "#listitems tr" ).click(function(event) { alert("clicked"); }); }); For some reason, the first function declaration for the "create-discussion" button works perfectly; when clicked, a popup appears. However, the second one does not work, and no popup is
