    dsonesuk...What an incredible gift you have given me. Thank you. I know that all of your Moderating takes up a great deal of time an effort, and so I want to say how appreciative I am of the time spent educating me. This was undoubtedly the best teaching on the web! I'm glad to say...I"VE GOT IT!!! -Doc

    Wow. This is so readable and helps me immensely to understand the flow. Thanks, Dave. dsonesuk, I'm not saying yours isn't, but I am saying that I am so new to this stuff, that your explanation goes right over the top of my head. I'm just barely above the level of "See Spot run. Run Spot run " (A children's book in case you're not from a country or a time when this book was in use teaching children to read :-) Dave and ds, for the sake of my education, is there not a simpler way than having to break the script down into 3 functions? For example, is it possible to include init and run within createString? Thanks so much both of you!!!! Doc

    So once I have targetted the userInput.value, how do I get it into the parameters for createString if not through a var like n?

    Oops. I didn't finish my thought... Instead of hard-coding an input and outputting to the console, I am trying to pass the value of an input to the function and then output it using .innerHTML.

    Hello: Below I successfully created a random string generator in js. As you can see, to verify it worked,I logged the output to the console. Now I have tried for hours to do something I thought was incredibly easy, and it probably would be if it weren't I trying to author it :-0 Commented out is the latest of my attempts to do so. The live code works correctly. <!doctype html><html><head><meta charset="utf-8"><title>Random String</title></head><body><!-- <h3>Please input a number to represent how long of a string you wish to randomly create</h3><input name= "userInput" id="userInput" maxlength="2"><button type="submit" onClick="createString()">Submit</button> <p id="output"></p>--><script>//Create function that will produce a random string from a supplied set of characters.function createString(n) { //Declare String Variable.var text = "";// n = [];//List of characters to be drawn fromvar char_list = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789"; //Loopfor(var i=0; i < n; i++ ) { text += char_list.charAt(Math.floor(Math.random() * char_list.length)); } //Return the value of the function to the var "test"return text; } //Display the value of the returned random string to the console. Call the function with a parameter n of 10console.log(createString(10)); //document.getElementById("output").innerHTML= createString();</script></body></html> Can you help! Thanks so much, Doc

    In the following code: <codeblock> <script> $(document).ready(function(){ $("#hide").click(function(){ $("img").hide(); }); $("#show").click(function(){ $("img").show(); }); }); </script> </codeblock> Is my method and syntax correct for hiding an <img>? Thanks, Doc

    justsomeguy: Unfortunately when I click the button it does nothing. There are no syntax errors so I don;t know what it is. It looks right... Doc

    So here is my program to take a user input, process it for all possible word combinations and then output the resulting string array to a p string I have been working on this for weeks and was sure I had finally gotten it. Can anyone help? Thanks! Doc <codeblock> <!doctype html> <html> <head> <meta charset="utf-8"> <title>Word Combinations</title> </head> <body> <h3>Please input a word to be processed for all of its possible combinations:</h3> <input id="userInput" type="text" autofocus="autofocus"> <button id="processInput" onClick="getAnagrams("userInput")">Process</button> <p id="returnValue"></p> <script> function swap(chars, i, j) { var tmp = chars; chars = chars[j]; chars[j] = tmp; } function getAnagrams(input) { //initialize the variables var counter = [], anagrams = [], chars = input.split(''), length = chars.length, i; //determine how many letters are in the string for (i = 0; i < length; i++) { counter = 0; } // for loop 1st it will set i to 0; then if i < 3 (using Dog); increment by 1's //next loop sets i to 1; i is still less than 3; so increment by 1 again //next loop sets i to 2; i is still less than 3; so increment by one again //next loop sets i to 3; i is NO LONGER less than 3 so loop stops and returns a string length of 3 (0,1,2 = 3 in the array) //push the original string in container anagrams.push(input); //the (input) string 'dog' is put into the anagrams container //start from first letter i = 0; while (i < length) { if (counter < i) { // i is now = to 0 in the array = 'd' // WHILE i < 3 and IF the loop counter is less than 3 then perform the following //swap the two letters in questions swap(chars, i % 2 === 1 ? counter : 0, i); //increment counter counter++; i = 0; //push new combination into container anagrams.push(chars.join('')); } else { counter = 0; //increment counter i++; } } //return string of results // return anagrams; //Place the result of anagrams into the p id = "returnValue" document.getElementById("returnValue").innerHTML = anagrams; } </script> </body> </html> </codeblock>

    Thanks. It is such a big mtn to climb. Thanks for your help. Any opinion on should I learn something like Angular.js to bootstrap etc? And if so, before I do .js or after?
  10. DocGrimwig
    I understood permutations to mean: d, o, g, do, od, dg, gd.....dog, dgo, odg ect... So what is the above??
  11. DocGrimwig
    yes

    I'm so new to this. I'm an idiot "justsomeguy." I don;t need recursion after all, I am thinking incorrectly. I just need to get it accomplished. I feel stupid.
  13. DocGrimwig
    I have been trying to apply the theory of recursion to practical application within a JS function. At first I thought it would be easy. I have found several attempts, but most are all over the place and it's hard to follow them and to learn something from them. I have spent days with others, only to discover they are not using proper JS protocols. Can anyone link me to a GREAT Word Combination (recursive, repeating) -permutations, JS function that finds all of the combinations of an input word and displays them in the browser? I am so new that I can't tell what's good or what's bad. Thanks! Doc

    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>

    Thanks Again Foxy.

    Ok, so this is too much! Thank you!!!!!!!!!!!! Do you like Starbucks or something else?
  17. DocGrimwig
    I am new to js and am trying to learn something via the following snippet: <code> function substrings(str1) { var array1 = []; for (var x = 0, y=1; x < str1.length; x++,y++) { array1[x]=str1.substring(x, y); } var combi = []; var temp= ""; var slent = Math.pow(2, array1.length); for (var i = 0; i < slent ; i++) { temp= ""; for (var j=0;j<array1.length;j++) { if ((i & Math.pow(2,j))){ temp += array1[j]; } } if (temp !== "") { combi.push(temp); } } document.write.log(combi.join("n")); } substrings("dog"); </code> (1) how can I change the output to go to my browser instead of the console and (2) can someone please answer a stupid question like what is the benefit of writing to the console. As I said I am totally new and don't have handle on the uses of the console yet. I know its for debugging, i think... :-)

    Thanks again for your reply. Your help is invaluable. Do you know if there are copyright laws specifically directed toward web based applications?
  19. DocGrimwig
    Thanks so much! Well then, here we go, into the deep water! :-)

    I am a complete Newbie and will be embarking on a big project to use a device for learning the web dev languages. That being said, with the availability of page source code info, inspect element etc. What should I be studying at the outset so that my design can't merely be cut and pasted and sold after all my hard work. I know there are copyrights laws, but we all no they are only a good as the paper they were written on if a person is determined to pirate something.

    I have been toying with web development for 10+years using tools like MUSE to make it easier. That has become so unsatisfying. So I am wanting to learn both client-side and server-side languages by creating a large robust database driven application that runs completely in the cloud. This app will be somewhat like a service desk app in that it will take in much data and based upon each user input, will cause a multitude of actions such as: contacting by email a person to handle the case, open a case file and place it within one of several appropriate scenarios in order to properly bring the case to resolve. Each of these scenarios will have its own ("to-do) list, case management and personnel notification. From this limited information, are you able to render a conclusion as to whether or not I can do this all in the web, or will I have to learn another programming language (ie. C+, C#) that will have to be compiled and executed on the clients local device? Thanks for your help! Doc
