For example, an enumeration type that defines an error Copy Code code as follows: public enum Eerrordetailcode:int { Landing success = 0, Log out = 1, Application Error = 2, Success = 16, Failure = 17 } Need to reference Using System; Then in the loop, iterate through all the elements of the enumeration object Copy Code code as follows: foreach (int

Problem Description: Given a character array words, and the string s, returns the position of a substring of all the character elements in the character array in the string, requiring all elements in the string array to exist only once in the string s.Algorithmic analysis: This problem is similar to STRSTR. Just Strstr

This method is used to search for all sibling elements before the current element is found on the basis of the selector until the matching element is encountered:If the provided jquery represents a set of DOM elements, the. Prevuntil () method also allows us to search through the DOM tree where all the

Php traverses all elements in the class. Php traversal method of all elements contained in the class. This article describes the methods of all elements contained in the php traversal class. Share it with you for your reference. T

What's more, there's something about selectors.Background: Find all the input elements in a control with the following code:1 $ ("#div1"). Find ("input"). each (function () {2 Alert ($ (this). attr ("value")); 3 });The jquery code above is looking for all input elements under the DIV elemen

not careful you will encounter some pits that are difficult to spot, resulting in a program that is not as expected. The pit here is the problem of traversing the list through a for loop and removing all elements. For example, the following example program creates a list, stores 0-3 sequentially, and then iterates through the list with a for loop to delete all t
