javascript - can anyone offer help on how to make this code more efficient? -


I am very new to coding, so please forgive me a newbie mistakes made by me. Any and all help is appreciated!

By using the GVT API, I was able to drag images from the Flix database and was able to put them in a spread sheet, but my used process seems to be unnecessarily painstaking.

Here is the function that I used to draw the image URL from the database: 

  function kwURL (keyword) {var response = UrlFetchApp.fetch ("https: / /www.flickr.com/search/?q= "+ keyword) var content = response.getContentText (); Var length = content.length; Var calculation = 0; (Var i = 0; i & lt; = length -3; i ++) {if (content.substring (i, 5 + i) .equals ("src = \" ")) {var start = I + 5 ; Count + 1 (if (content.substring (e, e + 1) .equals ("\" ")) {var end = 1} (count == 4) {for (var e = start; e & lt; Length-1; e ++) e break;}}} If (calculation == 4) {break;}}} Logger.log (content.substring (start, end)); return content.substring (start, end) :}   
 The fourth image, like the logo page and the luggage, from the first three, chooses the fourth image.  
 Here is the code that draws the word from the first column and flicker database Finds keywords in and the image found in the second column Contains:  
  function on change () {var sheet = SpreadsheetApp .getActiveSheet (); Var rows = sheet.getDataRange (); var numRows = rows.getNumRows (); (Var {Var keyword = sheet.getRange (i, 1) .getValue (); if (keyword! = "") {Sheet.insertImage (kwURL) for i = 2; i & lt; = numRows + 2; i ++) (Keyword), 2, i);}}}   
 I could not find another program that was trying to do the same thing in Google Apps Script documentation or programs Which I searched on the internet, so hopefully someone has this dirty code Made it clear that I have made from scratch.  
  
 
 
 Use of screen-scraping (which is essentially what you are doing here) Should be done in the form. Any changes in the web page you are bringing may possibly break your code. A better way to solve your problem is to use a publicly available API for third-party developers who are requesting some data in a standard format. And it looks like Flickr: (Note: I have no experience with this API. I just found out that it exists after a quick Google search).  
 If you get the proper API resource, then you should be a JSON object with a list of URLs pointing back to the images directly.  or  if there is any other weird  loops for loops, or something else ugly  (magicString == '\ "src \"' ')  or   > (magicNumber == 4) / Code> Code At that time it should be very simple to include these pictures in these spreadsheets.

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise. To clarify - this will not be a method error because it is a linked list. There should not be any way involved. import java.awt. *; Import java.awt.event. *; Import javax.swing. *; Import java.util. *; Import java.util.Scanner; Import java.util.LinkedList; Public class TopTenList JFrame {Private TopTenList tt; See the Private JTextArea list; Private JTextField cmdTextField; Private JTextField resultsTestfield; // This GUI window is the code for the public toptist...

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
