How to create a dynamic form using jQuery? -


I've seen a lot of help in dynamically adding rows or areas, but I'm interested in controlling those areas Which are dependent

For example, I have a form with 3 user input: 

  & lt; Select id = "foo" & gt; & Lt; Option value = "0" & ​​gt; No & lt; / Options & gt; & Lt; Option value = "1" & gt; Yes & lt; / Options & gt; & Lt; / Select & gt;   
 When the value of  #foo  is set to  1 , then I would like to enable  #bar . 
 
  & lt ;! - By default, the bar should be disabled - & gt; & Lt; Select ID = "bar" & gt; & Lt; Option value = "some_1" & gt; Some 1 & lt; / Options & gt; & Lt; Option value = "some_2" & gt; Some 2 & lt; / Option & gt; & Lt; Option value = "Other" & gt; Other ... & lt; / Options & gt; & Lt; / Select & gt;   
 When the value of  #bar  is set to  other , then I would like to enable  #baz . 
 
  & lt ;! - By default, baz should be disabled - & gt; & Lt; Textarea id = "baz" & gt; & Lt; / Textarea & gt;  
 
 
 My goal 
 
 I want to do some guidance on writing a small plugin which provides easy access to form input with dependency. 
 
 I need brief, concise syntax. Is there any way i can add HTML attributes help to the jQuery plugin in "Automating" things? 
 
 The closest issue 
 
     
  1.  if  #foo  is set to "yes", then  #bar  is set to "other" , Then  #foo  is set to "no"; I have the dependency of  #bar  inactive / hidden. 
    2.  
  2.  Input enabled / disabled and / or views / hidden; Being able to define custom behaviors for elements would be nice. 
    3.  
 
 Reinvent the wheel 
 
 If there is a plugin that does this kind of thing, then let me know! I'm unable to find anyone ...

Would you like to focus on event handling .change () as event your entry point Handler can see the form element id and value in a JSON structure to determine if the work should be done, if any. Javascript can look like this: 

  form = {"input1": {"value1": {/ * action list * / [{"hide": ["input2", "input3 {"Input 5": "true", "input 6": "wrong"}]}, "value 2": {{/ * tasks]: {"Input 4"}: "set" Another set of * /]}} function onchange (e) {id = $ (this) .attr ("id"); Value = $ (this) .val (); {$ (Action in "id"} {$ (in action [id]) {$ .ee (form [id] [value], function (i, action) {if ("hide" in action) $ {action ) Hide ();} /} etc;}}} $ {Document} .ready (function () {$ ("input") for other tasks. Change (on change);}

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
