ignace Posted April 19, 2010 Share Posted April 19, 2010 function getMask(theWord) { return theWord.toUpperCase().replace(/[A-Z]/, "_"); } function revealMask(theWord, wordMask, letter) { if (!letter) return theWord; var length = theWord.length; for (var i = 0; i < length; ++i) { if (theWord.charAt(i) == letter) { wordMask[i] = letter; } } return wordMask; } Don't use " _ " use CSS instead (letter-spacing) and use a monospaced font. It's funny you create something like this as I have created the same thing but used PHP instead you can have a look at: http://www.mediafire.com/file/wetmhyguem3/hangman.zip I use it mainly for my own pleasure and I don't recommend using it in any production environment Quote Link to comment https://forums.phpfreaks.com/topic/199044-display-first-letter-of-string-followed-by-_-_-_/#findComment-1044838 Share on other sites More sharing options...

Psycho Posted April 19, 2010 Share Posted April 19, 2010 Damn, salathe beat me to it. Ah well, here is a working example: <html> <head> <script type="text/javascript"> function displayPattern(theWord) { var pattern = theWord.replace(/(?!^)\w/g, "_") document.getElementById('pattern').innerHTML = pattern; return; } </script> </head> <body> Select a phrase:<br /> <select onchange="displayPattern(this.options[this.selectedIndex].value)"> <option value="">-- Select One --</option> <option value="The First Option">The First Option</option> <option value="Another Option">Another Option</option> <option value="Last Option">Last Option</option> </select> <br /><br /><br /> Pattern:<br /> <div id="pattern" style="letter-spacing:6px"></div> </body> </html> Quote Link to comment https://forums.phpfreaks.com/topic/199044-display-first-letter-of-string-followed-by-_-_-_/#findComment-1044855 Share on other sites More sharing options...
