password generator without repetition google sheets script editor

I have a code that generates a string of 6 characters, this code generates 3 different characters and 3-digital number in the column
I would like this code to check in this column cell by cell whether the values ​​generated by this generator are unique (they are not repeated). If he finds repetitive value ​​in the cell, I want to generate the value for the cell again.
Thank you in advance for your help

Highlighting works initially but does not when hash changes

I am developing an extension, which is about fetching the list of topics from the server and find if those topics match with the currently opened Gmail messages or not, if found then highlight that topic otherwise don't.
But if already 6 topics are matched, then it should not check or highlight other topics. This one is working but now I have a problem like if I go back from the current message and again come to that message then highlight won't be shown. Also if I open another message, the highlight is not done.
If I remove the code of counter check from the following snippet it works but this will highlight all the topics that are matched instead of just max 6 topics.
var count = 1;
var highlightAllWords = function(topics) {
Object.keys(topics.topics).forEach(function(topic) {
if (count <= 6) {
highlightTopic(topic);
if (topic !== null || !topic.length) {
count += 1;
}
}
});
};
// init highlight CSS
var ruleExistenceDict = {};
var sheet = (function() {
var style = document.createElement('style');
style.appendChild(document.createTextNode('')); // WebKit hack ##
document.head.appendChild(style);
return style.sheet;
})();
var topicData = {

function searchPage(topics) {

}
var count = 1;
var highlightAllWords = function(topics) {
Object.keys(topics.topics).forEach(function(topic) {
if (count <= 6) {

}
}

// console.log(word, startingIndex, n.parentNode, n.textContent);

if (startingIndex !== -1) {
var topicRange = document.createRange();
topicRange.setStart(n, startingIndex);
topicRange.setEnd(n, startingIndex + topic.length);
rangeList.push(topicRange);
}
} while (startingIndex !== -1);
// highlight all ranges

};
Here is the full code:
https://gist.github.com/MilanRgm/5d6b9861be1326ba8b049ccfb6c3b376

You should declare the count variable inside the function, so that every time you refresh the page, the count will start from 1 again. Please update your code as follows:
var highlightAllWords = function(topics) {
var count = 1;
Object.keys(topics.topics).forEach(function(topic) {
if (count <= 6) {
highlightTopic(topic);
if (topic !== null || !topic.length) {
count += 1;
}
}
});
};

could not highlight gmail content up to 6

I am developing an extension which is about fetching the list of topics from the server and find if those topics match with the currently opened gmail messages or not, if found then highlight that topic otherwise don't. But if already 6 topics are matched then it should not check or highlight other topics.
I have used the treewalker for crawling the gmail contents so the matched content will get highlighted as follow
function searchPage(topics) {
highlightAllWords(topics);
}
var highlightAllWords = function(topics) {
Object.keys(topics.topics).forEach(function(topic) {
highlightTopic(topic);
})
}
function highlightTopic(topic) {
let found = 0;
if (topic == null || topic.length === 0) return;
var topicRegex = new RegExp(topic, 'gi');
var treeWalker = document.createTreeWalker(
document.body,
NodeFilter.SHOW_TEXT,
{
acceptNode: function(node) {
var result = NodeFilter.FILTER_SKIP;
if (topicRegex.test(node.nodeValue)) {
found += 1
console.log('found', found);
if (found <= 6) {
console.log('foound less than 6', found)
result = NodeFilter.FILTER_ACCEPT
return result;
}
};
}
}, false
)
var skipTagName = {
"NOSCRIPT": true,
"SCRIPT": true,
"STYLE": true
}
var nodeList = [];
while (treeWalker.nextNode()) {
if (!skipTagName[treeWalker.currentNode.parentNode.tagName]) {
nodeList.push(treeWalker.currentNode);
}
}
nodeList.forEach(function (n) {
var rangeList = [];
// find sub-string ranges
var startingIndex = 0;
do {
// console.log(word, startingIndex, n.parentNode, n.textContent);
startingIndex = n.textContent.indexOf(topic, startingIndex + 1);
if (startingIndex !== -1) {
var topicRange = document.createRange();
topicRange.setStart(n, startingIndex);
topicRange.setEnd(n, startingIndex + topic.length);
rangeList.push(topicRange);
}
} while (startingIndex !== -1);
// highlight all ranges
rangeList.forEach(function (r) {
highlightRange(r);
});
});
}
// highlight the keyword by surround it by `i`
var highlightRange = function (range) {
const bgColorCode = '#000000';
var anchor = document.createElement("A");
var selectorName = anchor.className = "highlighted_text";
anchor.classList.add("highlighted_text");
// range.surroundContents(iNode) will throw exception if word across multi tag
if (!ruleExistenceDict[bgColorCode]) {
sheet.insertRule([".", selectorName, " { background: #", bgColorCode, " !important; }"].join(""), 0);
ruleExistenceDict[bgColorCode] = true;
console.log(sheet);
}
anchor.appendChild(range.extractContents());
anchor.href = `https://google.com/?search=${
range.extractContents()
}`;
range.insertNode(anchor);
};
It highlights the matched content in gmail messages but does highlights more than 6 contents. I have taken the screenshot and it is something like this
update after counter increased and checked in treewalker.nextnode()

There are two syntax errors in your code. You are missing semicolon at end of this statement
found += 1;
Secondly, there is also one extra ";" at the end of function(node).
And You can add the counter check in the following code snippet as
var count=1;
while (treeWalker.nextNode() && count<=6) {
if (!skipTagName[treeWalker.currentNode.parentNode.tagName]) {
nodeList.push(treeWalker.currentNode);
count=count+1;
}
}
So, the final script for the function highlightTopic(topic) will look like
function highlightTopic(topic) {
let found = 0;
if (topic == null || topic.length === 0) return;
var topicRegex = new RegExp(topic, 'gi');
var treeWalker = document.createTreeWalker(
document.body,
NodeFilter.SHOW_TEXT,
{
acceptNode: function(node) {
var result = NodeFilter.FILTER_SKIP;
if (topicRegex.test(node.nodeValue)) {
found += 1;
console.log('found', found);
if (found <= 6) {
console.log('foound less than 6', found)
result = NodeFilter.FILTER_ACCEPT
return result;
}
}
}
}, false
)
var skipTagName = {
"NOSCRIPT": true,
"SCRIPT": true,
"STYLE": true
}
var nodeList = [];
var count=1;
while (treeWalker.nextNode() && count<=6) {
if (!skipTagName[treeWalker.currentNode.parentNode.tagName]) {
nodeList.push(treeWalker.currentNode);
count=count+1;
console.log('count:'+count);
}
}
nodeList.forEach(function (n) {
var rangeList = [];
// find sub-string ranges
var startingIndex = 0;
do {
// console.log(word, startingIndex, n.parentNode, n.textContent);
startingIndex = n.textContent.indexOf(topic, startingIndex + 1);
if (startingIndex !== -1) {
var topicRange = document.createRange();
topicRange.setStart(n, startingIndex);
topicRange.setEnd(n, startingIndex + topic.length);
rangeList.push(topicRange);
}
} while (startingIndex !== -1);
// highlight all ranges
rangeList.forEach(function (r) {
highlightRange(r);
});
});
}
Please update me if it worked.
Thanks
Edit:
And also update the function highlightAllWords as follow:
var highlightAllWords = function(topics) {
var count=1;
Object.keys(topics.topics).forEach(function(topic) {
if(count<=6){
highlightTopic(topic);
console.log('counter:'+count);
if (topic != null && topic.length != 0)
count=count+1;
}
})
}

Sorting two similar tables simultaneously

I've two tables which has exactly same columns. These tables are placed besides each other. Currently they are sorted separately. I want them to be sorted together. i.e. when I click on first column header of table 1 both tables should be sorted as if both are a single table.
This is the .js which I am using
function SortableTable (tableEl) {
this.tbody = tableEl.getElementsByTagName('tbody');
this.thead = tableEl.getElementsByTagName('thead');
this.tfoot = tableEl.getElementsByTagName('tfoot');
this.getInnerText = function (el) {
if (typeof(el.textContent) != 'undefined') return el.textContent;
if (typeof(el.innerText) != 'undefined') return el.innerText;
if (typeof(el.innerHTML) == 'string') return el.innerHTML.replace(/<[^<>]+>/g,'');
}
this.getParent = function (el, pTagName) {
if (el == null) return null;
else if (el.nodeType == 1 && el.tagName.toLowerCase() == pTagName.toLowerCase())
return el;
else
return this.getParent(el.parentNode, pTagName);
}
this.sort = function (cell) {
var column = cell.cellIndex;
var itm = this.getInnerText(this.tbody[0].rows[1].cells[column]);
var sortfn = this.sortCaseInsensitive;
if (itm.match(/\d\d[-]+\d\d[-]+\d\d\d\d/)) sortfn = this.sortDate; // date format mm-dd-yyyy
if (itm.replace(/^\s+|\s+$/g,"").match(/^[\d\.]+$/)) sortfn = this.sortNumeric;
this.sortColumnIndex = column;
var newRows = new Array();
for (j = 0; j < this.tbody[0].rows.length; j++) {
newRows[j] = this.tbody[0].rows[j];
}
newRows.sort(sortfn);
if (cell.getAttribute("sortdir") == 'down') {
newRows.reverse();
cell.setAttribute('sortdir','up');
} else {
cell.setAttribute('sortdir','down');
}
for (i=0;i<newRows.length;i++) {
this.tbody[0].appendChild(newRows[i]);
}
}
this.sortCaseInsensitive = function(a,b) {
aa = thisObject.getInnerText(a.cells[thisObject.sortColumnIndex]).toLowerCase();
bb = thisObject.getInnerText(b.cells[thisObject.sortColumnIndex]).toLowerCase();
if (aa==bb) return 0;
if (aa<bb) return -1;
return 1;
}
this.sortDate = function(a,b) {
aa = thisObject.getInnerText(a.cells[thisObject.sortColumnIndex]);
bb = thisObject.getInnerText(b.cells[thisObject.sortColumnIndex]);
date1 = aa.substr(6,4)+aa.substr(3,2)+aa.substr(0,2);
date2 = bb.substr(6,4)+bb.substr(3,2)+bb.substr(0,2);
if (date1==date2) return 0;
if (date1<date2) return -1;
return 1;
}
this.sortNumeric = function(a,b) {
aa = parseFloat(thisObject.getInnerText(a.cells[thisObject.sortColumnIndex]));
if (isNaN(aa)) aa = 0;
bb = parseFloat(thisObject.getInnerText(b.cells[thisObject.sortColumnIndex]));
if (isNaN(bb)) bb = 0;
return aa-bb;
}
// define variables
var thisObject = this;
var sortSection = this.thead;
// constructor actions
if (!(this.tbody && this.tbody[0].rows && this.tbody[0].rows.length > 0)) return;
if (sortSection && sortSection[0].rows && sortSection[0].rows.length > 0) {
var sortRow = sortSection[0].rows[0];
} else {
return;
}
for (var i=0; i<sortRow.cells.length; i++) {
sortRow.cells[i].sTable = this;
sortRow.cells[i].onclick = function () {
this.sTable.sort(this);
return false;
}
}
}
There are just two columns and are likely to remain the same. Some ideas would be really appreciated.

I don't quite follow the HTML you have (since you didn't include any HTML), so I created a simple version myself here and implemented a sort across tables. The basic idea is that it collects all the data out of the tables into a single javascript data structure, sorts the javascript data structure and then puts all the data back into the tables.
This makes the sorting much simpler and the only places you have to deal with the complexities of multiple tables is when retrieving the data and then putting it back into the tables. You can see it work here: http://jsfiddle.net/jfriend00/Z5ywA/. Just click on a column header to see both tables sorted by that column.
The code is this:
function sortTables(colNum) {
var t1 = document.getElementById("table1");
var t2 = document.getElementById("table2");
var data = [], sortFn;
function sortAlpha(a, b) {
// deal with empty strings
var aa = a[colNum].data, bb = b[colNum].data;
if (!aa) {
return(!bb ? 0 : -1);
} else if (!bb){
return(1);
} else {
return(aa.localeCompare(bb));
}
}
function sortNumeric(a, b) {
// deal with possibly empty strings
var aa = a[colNum].data, bb = b[colNum].data;
if (typeof aa == "string" || typeof bb == "string") {
return(sortAlpha(a, b));
} else {
return(aa - bb);
}
}
// get the data
function getData(table) {
var cells, rowData, matches, item, cellData;
var rows = table.getElementsByTagName("tbody")[0].getElementsByTagName("tr");
for (var i = 0; i < rows.length; i++) {
rowData = [];
cells = rows[i].getElementsByTagName("td");
for (var j = 0; j < cells.length; j++) {
// add each cell in the row to the rowData data structure
item = {};
item.origStr = cells[j].textContent || cells[j].innerText;
cellData = item.origStr.replace(/^\s*|\s*$/g, "").toLowerCase();
if (cellData.match(/^[\d\.]+$/)) {
cellData= parseFloat(cellData);
} else if (matches = cellData.match(/^(\d+)-(\d+)-(\d+)$/)) {
cellData= new Date(
parseInt(matches[3], 10),
parseInt(matches[1], 10) - 1,
parseInt(matches[2], 10)
);
}
item.data = cellData;
// determine the type of sort based on the first cell we find
// with data in the column that we're sorting
if (!sortFn && item.data !== "" && j == colNum) {
if (typeof item.data == "number" || typeof item.data == "object") {
sortFn = sortNumeric;
} else {
sortFn = sortAlpha;
}
}
rowData.push(item);
}
// add each row to the overall data structure
data.push(rowData);
}
}
// put data back into the tables
function putData(table) {
var cells, rowData, item;
var rows = table.getElementsByTagName("tbody")[0].getElementsByTagName("tr");
for (var i = 0; i < rows.length; i++) {
cells = rows[i].getElementsByTagName("td");
for (var j = 0; j < cells.length; j++) {
// add each cell in the row to the rowData data structure
cells[j].innerHTML = data[0][j].origStr;
}
// remove this row
data.shift();
}
}
getData(t1);
getData(t2);
data.sort(sortFn);
putData(t1);
putData(t2);
return(false);

Js Pagination error

I need to perform a pagination where I need to display 5 rows every time. First 5 rows are displayed. On the second click, the next 5, the third rows no. 11-15, and so on. I need to display even if at least one row is there (after n clicks where totalRows mod 5 is less than 5). I do not get this.
function rightArrow()
{
pageCount = document.getElementById('pgCnt').value; //totalRows / 5
totCount = document.getElementById('totCnt').value; //totalRows
currPage = tempRows - pageCount + 2; //current set of rows
document.getElementById('tempPage').value = tempPage;
var m = totCount%5;
if(pageCount != tempRows)
m = 5;
else
{ m = (totCount % 5) - 1;
document.getElementById('rightArr').disabled = true;
}
document.getElementById('pgCnt').value = document.getElementById('pgCnt').value - 1;
for(i = 0; i < m;i++)
{
$.ajax({
type: "POST",
url: "getEODRow.php",
data: "page=" + currPage + "&row=" + i,
success: function(html)
{
var row = document.getElementById('chRecommend').insertRow(0);
temp = html.split(",");
for(j = 0; j < 9; j++)
{
str = temp[j].replace("\"","");
str = temp[j].replace("\"",'');
str = temp[j].replace("[",'');
col = row.insertCell(j);
col.innerHTML = str;
}
}
});
}
currPage++;
}

I realize this question is pretty much dead, but I came across it looking for something else, and I figured I'd toss an answer at it. Since it's not a critical issue, I went ahead and reworked everything you've got here plus a lot of code that you didn't choose to include.

with(MyApp.Paging.Model) {
return Math.ceil(itemCount/(itemsPerRow*rowsPerPage));
}
},
getPageSize: function() {
with(MyApp.Paging.Model) {
return itemsPerRow * rowsPerPage;
}
},
getItemsOnPage: function(pageNum) {
with(MyApp.Paging.Model) {
return Math.min(((pageNum+1) * getPageSize()), itemCount) - pageNum*getPageSize();
}
},
getItemsInRow: function(pageNum, rowNum) {
with(MyApp.Paging.Model) {
var onPage = getItemsOnPage(pageNum);
return Math.min((rowNum+1)*itemsPerRow, onPage) - rowNum*itemsPerRow;
}
},
getQueryData: function(itemPage, itemRow) {
with(MyApp.Paging.Model) {
var data = queryDataFormat;
data = data.replace(/{itemPage}/gi, itemPage);
data = data.replace(/{itemRow}/gi, itemRow);
return data;
}
}
};
So, whenever the page is loaded, with an onload handler or whatever, you would create and hang onto a singleton instance of the Paging Controller.
MyApp.Paging.Controller.instance = new MyApp.Paging.Controller();
This should handle issues with Ajax calls returning out of order as well as partial pages of data and partial rows within those pages.
