You can only place <h2> elements within <a> elements if you’re working with HTML5, which allows any other elements within <a> elements. Previous specifications (or current ones however you want to look at them) never allowed this. The usual way of doing this is to place <a> within <h2>. This works, has always worked, and … Read more
You could use event delegation on the parent div. Or use the closest method to find the parent of the button. The easiest of the two is probably the closest. var id = $(“button”).closest(“div”).prop(“id”);
We’ve developed a tool that is able to precisely deal with this scenario. Check http://www.semanticmerge.com It merges (and diffs) based on code structure and not using text-based algorithms, which basically allows you to deal with cases like the following, involving strong refactor. It is also able to render both the differences and the merge conflicts … Read more
In this case: i, a[i] = i + 1, i The righthand side evaluates to a tuple (1, 0). This tuple is then unpacked to i and then a[i]. a[i] is evaluated during the unpacking, not before, so corresponds to a[1]. Since the righthand side is evaluated before any unpacking takes place, referring to a[i] … Read more
Java restricts the types of expressions that are allowed in so-called “expression statements”. Only meaningful expressions that have potential side effects are allowed. It disallows semantically meaningless statements like 0; or a + b;. They’re simply excluded from the language grammar. A function call like foo() can, and usually does, have side effects, so it … Read more
Incrementing / Decrementing Operators ++ increment operator — decrement operator Example Name Effect ——————————————————————— ++$a Pre-increment Increments $a by one, then returns $a. $a++ Post-increment Returns $a, then increments $a by one. –$a Pre-decrement Decrements $a by one, then returns $a. $a– Post-decrement Returns $a, then decrements $a by one. These can go before or … Read more
First off, the facts: if (booleanValue) Will satisfy the if statement for any truthy value of booleanValue including true, any non-zero number, any non-empty string value, any object or array reference, etc… On the other hand: if (booleanValue === true) This will only satisfy the if condition if booleanValue is exactly equal to true. No … Read more
Both versions are correct. The biggest difference between them is that in the case of <h1><a>..</a></h1> only the text in the title will be clickable. If you put the <a> around the <h1> and the css display property is block (which it is by default) the entire block (the height of the <h1> and 100% … Read more
You might want to check out this paper: Sentence similarity based on semantic nets and corpus statistics (PDF) I’ve implemented the algorithm described. Our context was very general (effectively any two English sentences) and we found the approach taken was too slow and the results, while promising, not good enough (or likely to be so … Read more
As of C++14, they often are. C++14 adds a fringe case where parentheses around a return value may alter the semantics. This code snippet shows two functions being declared. The only difference is parentheses around the return value. int var1 = 42; decltype(auto) func1() { return var1; } // return type is int, same as … Read more
