javascript - Does an element with a specific innerHTML exist? -


I have a list of span amets with prices: 

    
 How can I see that there is a period with example "Example 4" for example?  
 I have made the following efforts so far with the following result:  
  if ($ ('span'). TextContent = value) {console.log ('exists '); } If ($ ('span'). Html (value) {} if ($ ('span'). Html (value) .length & gt; {} <}   
 but They always return true ..  
 Thanks for reading :)   
 
 
 A selector Is:  
  if ($ ('span: contains ("example4")). Length> 0) {...}   
 However If this    "Example 40" , then you can use the trick with the  .filter  method for the strict comparison of the approach:  
  if ($ ('span'). Filter (function () {return $ .trim ($ .text (this)) === 'example4';}). Length & gt; 0) {...}

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...

Calling a C++ function from C# by passing a string with variable size to it -

I am calling a string with a C + code and calling from the C # code. The C ++ function is responsible for filling the string material. The following code is: C #party: var abc = new string builder (4096); // will have to change this var result = Basic methods. SignCrcFile (ABC); C ++: bool __cdecl SignCrcFile (char * abc) {... char * tempStr = "hello all"; // for example // copy it to ABC string strcpy (ABC, tempStr); Back true; } The problem is that tempStr's size in the C ++ function is dynamic (the above assignment for TempStr is only an example). In such a case, it is not a hard code that the size of ABC string is in the size of 4096 bytes on the C #. The first solution can be a solution to create 2 functions on the C ++ side to get the size of the string. Then allocate that size using StringBuilder in the C # side then use the next function to bring the entire string from C ++ to the C #. But no suggestion this may not be the most optimal way? ...
