You just need to remove the parenthesis: addContact(entityId, refreshContactList); This then passes the function without executing it first. Here is an example: function addContact(id, refreshCallback) { refreshCallback(); // You can also pass arguments if you need to // refreshCallback(id); } function refreshContactList() { alert(‘Hello World’); } addContact(1, refreshContactList);
A parameter is a variable in a method definition. When a method is called, the arguments are the data you pass into the method’s parameters. public void MyMethod(string myParam) { } … string myArg1 = “this is my argument”; myClass.MyMethod(myArg1);
setTimeout(function() { postinsql(topicId); }, 4000) You need to feed an anonymous function as a parameter instead of a string, the latter method shouldn’t even work per the ECMAScript specification but browsers are just lenient. This is the proper solution, don’t ever rely on passing a string as a ‘function’ when using setTimeout() or setInterval(), it’s … Read more
You can parameterize each value, so something like: string[] tags = new string[] { “ruby”, “rails”, “scruffy”, “rubyonrails” }; string cmdText = “SELECT * FROM Tags WHERE Name IN ({0})”; string[] paramNames = tags.Select( (s, i) => “@tag” + i.ToString() ).ToArray(); string inClause = string.Join(“, “, paramNames); using (SqlCommand cmd = new SqlCommand(string.Format(cmdText, inClause))) { … Read more
There are two typical ways of declaring a function. I prefer the second approach. function function_name { command… } or function_name () { command… } To call a function with arguments: function_name “$arg1” “$arg2” The function refers to passed arguments by their position (not by name), that is $1, $2, and so forth. $0 is … Read more
The flag Xmx specifies the maximum memory allocation pool for a Java Virtual Machine (JVM), while Xms specifies the initial memory allocation pool. This means that your JVM will be started with Xms amount of memory and will be able to use a maximum of Xmx amount of memory. For example, starting a JVM like … Read more
The values are sent in the request body, in the format that the content type specifies. Usually the content type is application/x-www-form-urlencoded, so the request body uses the same format as the query string: parameter=value&also=another When you use a file upload in the form, you use the multipart/form-data encoding instead, which has a different format. … Read more
No, the structure you found is how Java handles it (that is, with overloading instead of default parameters). For constructors, See Effective Java: Programming Language Guide’s Item 1 tip (Consider static factory methods instead of constructors) if the overloading is getting complicated. For other methods, renaming some cases or using a parameter object can help. … Read more
From ES6/ES2015, default parameters are in the language specification. function read_file(file, delete_after = false) { // Code } just works. Reference: Default Parameters – MDN Default function parameters allow formal parameters to be initialized with default values if no value or undefined is passed. In ES6, you can simulate default named parameters via destructuring: // … Read more
