regex - RegExp and special characters -

-

I need to use regexp to match and the code below works fine. However, I should keep dollar sign ($) as a true dollar mark and not a special character.

I have tried to leave but nothing is working. 

  IE: [^ $]

Here is the code. It works as expected, except $ or IS $. 

  textNode = "$ 19,000"; Regex = RegExp ("$ 19,000", 'ig'); Text = '$'; TextReplacerFunc: Function (TextNode, Reggae, Text) {var sTag = '& lt; Span class = "highlight"> "; Var istag = '& lt; / Span & gt; '; Var re = '(?! [^ <> <>]>> (' + Text + '(?! # 8212;));'; Var regExp = new RegExp (again, 'IIG'); TextNode.data = textNode.data.replace (regExp, sTag + '$ 1' + tag); },

RESULT: $ not highlighted desired result: $ 19,000

Be sure to avoid $ : 

  text = '\\ $';

Since you are creating a RegExp example using a string here

uislider - In a MATLAB GUI, how does one implement a continuously varying slider from a GUIDE created .m file? -

-
I am trying to create a GUI with a plot and a slider. The slider should be described as continuously and output. I have a problem with this explanation that the uicontrol object is programmatically created, on the contrary, I want to know that in the last three instances, to complete the same thing done according to the program What can be added to a GUI file that is created. The code is down, and I have marked the (wrong) code that is provided by some of the above examples. Thanks a lot for any help! This slider function sets P1_slider_Callback (hObject, eventdata, handle) (handle, dragon, 'string', num2str (get (hObject, 'value'), 3)) PlottheData_Callback ( HOBject, EventData, Handle)% "PlotHeadata" is a button that creates the data slider based on the value of P1_slider%, and I think that here "p1_slider_CreateFcn" (hObject, eventdata, handle) needs to be assembled (HOBJECT, 'BackgroundRoller'), (0, 'Default UITTACKBACK MANDROLLE...

python - Django Custom Admin Block For center of admin -

-
So I'm overriding change_form.html to add some features to my admin page. Everything is working fine, I am currently using the "after_field_sets" block, but I want to put content between this field in my field_sets, not after that. I set the field above and below the new set, but I can not understand which block is used to put them in the middle of field sets. There is a list of all blocks text "> After reading the code referenced by the link you posted I reached the conclusion that the block you are looking for does not exist in it called content There is a block but more than just that "main content" but this is not the end of the world, you still have to make the template IR order to "make some space" for your content. Remember Padit can. And very important, keep in mind that you can css and js edit files as well.
