In the above code, that is not complete, but which implements quine Mccluskey algorithm. There is a problem while it is debugged.
If a breakpoint is inserted at gFormula.reducetoPrimeImplicants(); the debugger does not go into that function. This is the last function called in the code until now. But, it does go to start(), which is the first function.
There is some problem in reducetoPrimeImplicants(); function because it also gives ERROR in internet explorer.
I am not able to figure out the error. If I remove reducetoPrimeImplicants(); function from the code the works fine.
Please, can somebody tell me why the debugger does not enter reducetoPrimeImplicants();.
I am using the Firebug debugger.
Thanks in advance.
The last function in your page combine() is missing a closing brace.
If you don't mind, a suggestion: Please use http://jsbeautifier.org/ or some similar tool to indent your code better.
Your For loop has two starting braces.
for (var i = 0; i < this.varVals.length; i++) {
{
So remove one. This should solve your problem.

I like to show my titles of posts on a specific page. It is more effective to get know what author have written than scroll all pages or navigate using archive widget.
I found code (code is below) for generate list that sort post titles alphabetically but I like to show titles in chronological order. There is lot of code example about this but they are outdated. They doesn’t work anymore after some changes in blogger platform.
How to change code to get post titles in chronological order and in format YYYY.MM.DD ?
<div>
<ul id="postList12"></ul>
</div>
<script type="text/javascript">
var startIndex = 1;
var maxResults = 150;
var allResults = [];
function sendQuery12() {
var scpt = document.createElement("script");
scpt.src = "/feeds/posts/summary?alt=json&callback=processPostList12&start-index=" + startIndex + "&max-results=" + maxResults;
document.body.appendChild(scpt);
}
function printArrayResults(root) {
//Sort Alphebetically
allResults.sort(function(a, b)
{
var a_string = a.children[0].textContent ;
var b_string = b.children[0].textContent ;
if(a_string < b_string) return -1;
if(a_string > b_string) return 1;
return 0;
})
var elmt = document.getElementById("postList12");
for (index = 0; index < allResults.length; index++) {
elmt.appendChild(allResults[index]);
}
}
function processPostList12(root) {
var elmt = document.getElementById("postList12");
if (!elmt)
return;
var feed = root.feed;
if (feed.entry.length > 0) {
for (var i = 0; i < feed.entry.length; i++) {
var entry = feed.entry[i];
var title = entry.title.$t;
var date = entry.published.$t
for (var j = 0; j < entry.link.length; j++) {
if (entry.link[j].rel == "alternate") {
var url = entry.link[j].href;
if (url && url.length > 0 && title && title.length > 0) {
var liE = document.createElement("li");
var a1E = document.createElement("a");
a1E.href = url;
a1E.textContent = title + " (" + date.substr(0,10) + ")";
liE.appendChild(a1E);
//elmt.appendChild(liE);
allResults.push(liE);
}
break;
}
}
}
if (feed.entry.length >= maxResults) {
startIndex += maxResults;
sendQuery12();
} else {
printArrayResults();
}
}
}
sendQuery12();
</script>
Code is copied from here: https://dansator.blogspot.fi/2015/10/general-alphabetical-list-of-posts.html
Remove sort method from the code. remove the following :
//Sort Alphebetically
allResults.sort(function(a, b){
var a_string = a.children[0].textContent ;
var b_string = b.children[0].textContent ;
if(a_string < b_string) return -1;
if(a_string > b_string) return 1;
return 0;
})
Your code should be
<div>
<ul id="postList12"></ul>
</div>
<script type="text/javascript">
var startIndex = 1;
var maxResults = 150;
var allResults = [];
function sendQuery12()

This code works fine except one problem. The code generates small images ( in default blogger thumbnail size which is s72-c) and there is no way to customize the size for (to change s72-c to s200/s200-c/w200).
I have found a image re-sizing solution script for Blogger but they are not helping. Here is it
function resizeThumb(size) {
var popularPost = document.getElementById('PopularPosts1');
var image = popularPost.getElementsByTagName('img');
for (var i = 0; i < image.length; i++) {
image[i].src = image[i].src.replace(/\/s72\-c/g, "\/s" + size + "-c")
}
}
resizeThumb(200);
This is for Popular post widget. And I know if I change the ID in the first line this will replace the image. But this is not solution but a cover up. And this also means the two images are loaded on is s72-c and the replaced one.
I want to integrate it (something like this) in the first related post script. I have tried hard with very very little knowledge of javascript I have but fail. So I signed up to stackoverflow and this is my question post.
Thank you in advance for trying to the help me.
function code for image size s200-c
function resizeThumb(size) {
var popularPost = document.getElementById('PopularPosts1');
var image = popularPost.getElementsByTagName('img');
for (var i = 0; i < image.length; i++) {
image[i].src = image[i].src.replace(/\/s200\-c/g, "\/s" + size + "-c")
}
}
resizeThumb(200);
function code for image size s200
function resizeThumb(size) {
var popularPost = document.getElementById('PopularPosts1');
var image = popularPost.getElementsByTagName('img');
for (var i = 0; i < image.length; i++) {
image[i].src = image[i].src.replace(/\/s200\/g, "\/s" + size + "")
}
}
resizeThumb(200);
first,add
var thumb = 200;
after
var thumburl = new Array();
then
add
thumburl[relatedTitlesNum] = thumburl[relatedTitlesNum].replace("/s72-c/","/s"+thumb+"/");
after
thumburl[relatedTitlesNum] = entry.media$thumbnail.url;
hope you like it

I am new to coding Javascript. I am trying to to shuffle list of names inputted on a textarea. The user selects the number of groups desired, and shuffle on click, then show the divided groups as output result. Below is my code but it is not working as it should be, pls help!
<script>
function ArrayToGroups(source, groups){
var groupList = [];
groupSize = Math.ceil(source.length/groups);
var queue = source;
for(var r = 0; r < groups; r++){
groupList.push(queue.splice(0,groupSize));
}
return groupList;
}
function textSpliter(splitText){
var textInput = document.getElementById("inputText").value;
var splitText = textInput.split(',');
var newList = [];
for(x = 0; x <= splitText.length; x++) {
var random = Math.floor(Math.random() * splitText.length);
var p = splitText[random];
newList.push(p);
splitText.splice(p,groupList);
}
for(var i = 0; i < newList.length; i++){
var s = newList[i];
document.getElementById('resInput').value += s + "\n" ;

for (i = 0; i < n; i++) {
groups[i] = new Array();
for (j = 0; j < m; j++) {
// Random
rand = Math.floor(Math.random() * list.length);
// Add element to group
groups[i][j] = list[rand];
// Remove element to list
list.splice(rand, 1);
}
}
// Output
var text = "";
for (i = 0; i < n; i++) {
text += "Group " + (i + 1) + ": ";

I rewrote your code. It's pretty self-explanatory.

for (var i = 0; i < groupCount; i++) {
var group = [];

var random = Math.floor(Math.random() * names.length);
var name = names[random];
if (name != undefined) {
group.push(name);
names.splice(names.indexOf(name), 1);

function testPermutations() {
var expectedPermutations = ['atr', 'rat', 'rta', 'tar', 'tra', 'art'],
actualPermutations = calcPermutations(['a', 'r', 't']);
for(var i = 0; i < expectedPermutations.length - 1; i++) {
if(actualPermutations[expectedPermutations[i]] !== true) {
console.log("You're missing " + expectedPermutations[i]);
} else {
console.log("You've got " + expectedPermutations[i]);
}
}
return actualPermutations;
}
testPermutations();
When I run testPermutations and pass in a 3 letter word, it works fine. However, when I try four, a bunch of permutations are coming up missing. What's the flaw in my logic?
