No, don’t spoil the fun with a break. This is the last remaining valid use of goto 😉 If not this then you could use flags to break out of deep nested loops. Another approach to breaking out of a nested loop is to factor out both loops into a separate function, and return from … Read more
If you just want to take care of the newline chars in the text you could simulate it by splitting the text at the newlines and calling multiple times the fillText() Something like http://jsfiddle.net/BaG4J/1/ var c = document.getElementById(‘c’).getContext(‘2d’); c.font=”11px Courier”; console.log(c); var txt=”line 1\nline 2\nthird line..”; var x = 30; var y = 30; var … Read more
In the case of 2 nested loops: break 2; http://php.net/manual/en/control-structures.break.php
You can use goto. while ( … ) { switch( … ) { case …: goto exit_loop; } } exit_loop: ;
No, break is the correct solution. Adding a boolean variable makes the code harder to read and adds a potential source of errors.
Use the return keyword to exit from a method. public void someMethod() { //… a bunch of code … if (someCondition()) { return; } //… otherwise do the following… } From the Java Tutorial that I linked to above: Any method declared void doesn’t return a value. It does not need to contain a return … Read more
Break statements, The Go Programming Language Specification. A “break” statement terminates execution of the innermost “for”, “switch” or “select” statement. BreakStmt = “break” [ Label ] . If there is a label, it must be that of an enclosing “for”, “switch” or “select” statement, and that is the one whose execution terminates (§For statements, §Switch … Read more
You should be able to break to a label, like so: function foo () { dance: for (var k = 0; k < 4; k++) { for (var m = 0; m < 4; m++) { if (m == 2) { break dance; } } } }
A break will allow you continue processing in the function. Just returning out of the switch is fine if that’s all you want to do in the function.
break leaves a loop, continue jumps to the next iteration.
