DocGrimwig Posted September 21, 2015 Share Posted September 21, 2015 I am totally new to programming and am trying to adapt a snippet that was written to the console so that it now takes a user input and outputs to the browser. I have searched w3schools and other helps, but can't seem to get this last bit done. I don;t have any syntax issues apparently, and haven't earned to debug yet, so I've hit a wall. Can you help? <codebox> <!doctype html> <html> <head> <meta charset="utf-8"> <title>Possible Word Combinations</title> </head> <body> <h4>Please input a word below</h4> <input type="text" id="userInput" > <button onclick="scramble()">Submit</button> <p id="inputValue"></p> <script> function scramble(word) { var word = document.getElementById("UserInput") var words = [], rearrangedWord, head, tail; if (!word) { return words; } function rearrange(str, prefix) { prefix = prefix || ''; str.split('').map(function(head, idx) { tail = str.slice(0, idx) + str.slice(idx + 1); rearrangedWord = prefix + head + tail; if (words.indexOf(rearrangedWord) < 0) { words.push(rearrangedWord); } if (tail.length > 1) { rearrange(tail, prefix + head); } }); } rearrange(word, ''); return words; } document.getElementById("inputValue").innerHTML = words; (scramble("userInput")); </script> </body> </html> </codebox> Link to comment Share on other sites More sharing options...
Ingolme Posted September 21, 2015 Share Posted September 21, 2015 You have a function scramble(). It has a parameter "word", except that in the very first line of the function, you're overwriting that parameter so it's useless. Then you're calling the function, but not doing anything with its return value. This would probably improve your code a bit, but it still has problems: document.getElementById("inputValue").innerHTML = scramble(); Also, Javascript is case sensitive, this is a problem: document.getElementById("UserInput") <input type="text" id="userInput" > Link to comment Share on other sites More sharing options...
