Introduction:-
To understand this tutorial make sure that before you see this tutorial JavaScript :Tutorial, Loops and JavaScript :Tutorial, Your First Game! here we will elaborate a little more on these!
Explanation:-
In this tutorial the Explanation goes before the code too.
I hope this explained the basic concept on how to break out of loopsCode:while (something) { do something else if (something(while looping)) { end the loop }
Solution:-
Now here are some practical codes! Here
Explanation Of Code:-Code:<SCRIPT LANGUAGE="JavaScript"> var usrno = 0; while (usrno!=50) { usrno = window.prompt('Guess the number, enter end to finish',0); if (usrno=='end') { alert('Game Ended'); break; } if (usrno<50) { alert('too low'); } if (usrno>50) { alert('too high'); } } </SCRIPT>
This is the most important code. Here we are promoting the user ( see this tutorial JavaScript :Tutorial, Prompt ) and asking him to enter a number but if he instead writes 'end' without the ' ' the game will display an alert and we will break out of the loop, because of the 'break;' command!!Code:usrno = window.prompt('Guess the number, enter end to finish',0); if (usrno=='end') { alert('Game Ended'); break; }
