I am currently working on a little recreational Google Apps Script (GAS) for EVE Online and I have hit a brick wall when I am getting my server side functions talking to my client side ones.
HTML:
<form id="frm1" name = "mat_add">
<input width="1000" type="text" name="mat" value="Enter Item Here"><br />
<input type="button" value="Submit" name="mat_sub" onclick= "google.script.run.withSuccessHandler(onSuccess).shortlist(this.parentNode,document.getElementById('spn1').innerHTML)">
</form>
<span id="spn1"><table><tr><td>Type Name</td><td>Type ID</td></tr></table></span>
<script>
function onSuccess(output) {
document.getElementById(output[0]).innerHTML = output[1];
};
</script>
GAS:
function doGet() {
return HtmlService.createTemplateFromFile('Index').evaluate().setTitle('UMX Web App');
};
function include(filename) {
return HtmlService.createHtmlOutputFromFile(filename).getContent();
};
function shortlist(form,table) {
var arr = transpose(htmlToArray(table));
var item = form.mat;
if ( isNaN(item) ) {
var url = 'https://www.fuzzwork.co.uk/api/typeid2.php?format=xml&typename=' + item.toString();
} else {
var url = 'https://api.eveonline.com/eve/TypeName.xml.aspx?ids=' + item.toString();
};
var xml = UrlFetchApp.fetch(url).getContentText();
var document = XmlService.parse(xml);
var name = document.getRootElement().getChild('result').getChild('rowset').getChild('row').getAttribute('typeName').getValue();
if ( arr[0].indexOf(name) == -1 && name != 'Unknown Type' && name != 'bad item' ) {
arr[0].push(name);
arr[1].push(document.getRootElement().getChild('result').getChild('rowset').getChild('row').getAttribute('typeID').getValue());
};
var str = arrayToHTML(transpose(arr));
return ['spn1',str]
};
function arrayToHTML(arr) {
var i = 0;
var j = 0;
var str = '<table>';
while ( i < arr.length ) {
str = str + '<tr>';
while ( j < arr[i].length ) {
str = str + '<td>' + arr[i][j] + '</td>';
j += 1
};
str = str + '</tr>';
j = 0;
i += 1
};
str = str + '</table>';
return str
};
function htmlToArray(str) {
var arr1 = str.replace(/<tr>/g,'</tr>').split('</tr>');
var arr2 = [];
var i = 1;
var j = 1;
var x = [];
while ( i < arr1.length ) {
arr2.push([]);
x = arr1[i].replace(/<td>/g,'</td>').split('</td>');
while ( j < x.length ) {
arr2[arr2.length - 1].push(x[j]);
j += 2
};
j = 1;
i += 2
};
return arr2
};
function transpose(input) {
var output = [];
var i = 0;
var j = 0;
while ( i < input[0].length ) {
output.push([]);
while ( j < input.length ) {
output[i].push(input[j][i]);
j += 1
};
j = 0;
i += 1
};
return output
};
function direct(input) {
return input
}
The problem seems to be on the submit button because everything else is working fine. I have been looking for a workaround but that submit button is the only point of entry I can get and it will not accept more than one variable.
The problem seems to be on the submit button because everything else is working fine. I have been looking for a workaround but that submit button is the only point of entry I can get and it will not accept more than one variable.
Let's focus on this, and ignore all the irrelevant code. Basic question: how to get multiple inputs from a form to a server-side GAS function?
This example will demonstrate communication of the form object to the server, by throwing an error that contains all the received parameters. An errorHandler on the client side will alert with the received error message.
Index.html
<form id="frm1" name = "mat_add">
<input width="1000" type="text" name="mat" placeholder="Enter Item Here" /><br />
<input width="1000" type="text" name="mat2" placeholder="Enter Quantity Here" /><br />
<input type="button" value="Submit" name="mat_sub" onclick="google.script.run
.withSuccessHandler(onSuccess)
.withFailureHandler(onFailure)
.shortlist(this.parentNode)" />
</form>
<script>
function onSuccess(output) {
document.getElementById(output[0]).innerHTML = output[1];
};
function onFailure(error) {
alert( error.message );
}
</script>
Code.gs
function doGet() {
return HtmlService.createTemplateFromFile('Index').evaluate().setTitle('UMX Web App');
};
function shortlist(input) {
reportErr(JSON.stringify(input,null,2))
}
function reportErr(msg) {
throw new Error( msg );
}
Run this webapp, and here's your result:
The two named input elements, mat and mat2 were communicated to the server function shortlist() via the this.parent parameter. Since the button invoking this.parent in its clickHandler is contained in the frm1 form, all input elements of that form were included, and may be referenced on the server side as named properties of the input parameter of shortlist(). (NOT as array elements.)
The upshot of this is that your shortlist() function can be modified thusly:
function shortlist(input) {
var item = input.mat;
if ( isNaN(item) ) {
var url = 'https://www.fuzzwork.co.uk/api/typeid2.php?format=xml&typename=' + item;
} else {
var url = 'https://api.eveonline.com/eve/TypeName.xml.aspx?ids=' + item.toString();
};

Good evening. I am new to JavaScript and I need help with my mini-project and I have only one issue here and it is in the this.Add = function ().
It works properly when I enter a duplicate value from my list therefore it displays an alert that no dupes are allowed. But... when I enter a unique value, it only adds up the last element present (Wash the dishes) from myTasks list. instead of the one I recently entered and the list goes on adding the same ones. Did I just misplace something?
This is my final activity yet and I want to finish it to move to the next function. Thank you in advance.

In your for loop:
for (task of this.myTask) {
}
You are not declaring a new task variable, but instead assigning to the outer task variable, hence the repeated addition of tasks already in your list.
You can declare a new variable in the for scope like so:
for (const task of this.myTask) {
}
Your HTML as it is.
And your Javascript goes like below. You have a bug while checking if the task already exists in the array. As you're comparing string value either use simple for loop with triple equals or do as i have attached below.
var app = new function() {
this.el = document.getElementById('myTasks');
this.myTasks = ['Clean the bathroom', 'Wash the dishes'];
this.Count = function(data) {
var el = document.getElementById('counter');
var name = 'task';
if (data) {
if (data > 1) {
name = 'Things To DO';
}
el.innerHTML = data + ' ' + name ;
} else {
el.innerHTML = 'No ' + name;
}
};
this.FetchAll = function() {
var data = '';
if (this.myTasks.length > 0) {
for (i = 0; i < this.myTasks.length; i++) {
data += '<tr>';
data += '<td>' + this.myTasks[i] + '</td>';
data += '<td><button onclick="app.Edit(' + i + ')">Edit</button></td>';
data += '<td><button onclick="app.Delete(' + i + ')">Delete</button></td>';
data += '</tr>';
}
}
this.Count(this.myTasks.length);
console.log(this.myTasks.length);
return this.el.innerHTML = data;
};
this.Add = function () {
el = document.getElementById('add-task');
// Get the value
var task = el.value;
console.log(task);
if (task ){
var arrayContainsTask = (this.myTasks.indexOf(task) > -1);
if(arrayContainsTask == true){
window.alert("Duplicates not allowed.");
}else{
// Add the new value
this.myTasks.push(task);
// Reset input value
el.value = '';
}
// Dislay the new list
this.FetchAll();
}
}
}
I need to create a secret message app, such that a text:
"If man was meant to stay on the ground, god would have given us roots."
is normalized to:
"ifmanwasmeanttostayonthegroundgodwouldhavegivenusroots"
And the normalised text forms a rectangle (r x c) where c is the number of columns and r is the number of rows such that c >= r and c - r <= 1,
So for instance the normalized text is 54 characters long, dictating a rectangle with c = 8 and r = 7:
"ifmanwas"
"meanttos"
"tayonthe"
"groundgo"
"dwouldha"
"vegivenu"
"sroots "
Then the coded message is obtained by reading down the columns going left to right
"imtgdvsfearwermayoogoanouuiontnnlvtwttddesaohghnsseoau"
and further split to
"imtgdvs fearwer mayoogo anouuio ntnnlvt wttddes aohghn sseoau"
The resulting cypher text for a non perfect rectangle can only have a single whitespace for the last rows.
"imtgdvs"
"fearwer"
"mayoogo"
"anouuio"
"ntnnlvt"
"wttddes"
"aohghn "
"sseoau "
This what I have done so far, I could only get my normalised text, but I am doing something wrong to convert it to a rectangle and to get a cypher text out of it.
const output = document.querySelector('#encoded_rectangle');
const encodedChunks = document.querySelector('#encoded_chunks');
const text = document.querySelector('#normalized_text');
const string = document.querySelector('#message');
const error = document.querySelector('#alert');
const encodeMessage = () => {
let message = string.value;
function wordCount() {
return message.split(" ").length;
}
if (wordCount < 2 || message.length < 50) {
error.innerHTML = "Invalid message, Input more than one word and at Least 50 characters!";
return false;
}
function normaliseMessage() {
return message.replace(/[^a-zA-Z0-9]/g, "").toLowerCase();
}
function rectangleSize() {
return Math.ceil(Math.sqrt(normaliseMessage.length));
}
function splitRegEx() {
return new RegExp(".{1," + rectangleSize + "}", "g");
}
function plaintextSegments() {
return normaliseMessage.match(splitRegEx);
}
function ciphertext() {
var columns = [],
currentLetter, currentSegment;
var i, j;
for (let i = 0; i < rectangleSize; i++) {
columns.push([]);
}
for (i = 0; i < plaintextSegments.length; i++) {
currentSegment = plaintextSegments[i];
for (j = 0; j < columns.length; j++) {
currentLetter = currentSegment[j];
columns[j].push(currentLetter);
}
}
for (i = 0; i < columns.length; i++) {
columns[i] = columns[i].join("");
}
return columns.join("");
}
function normalizeCipherText() {
return ciphertext.match(splitRegEx).join(" ");
}
text.innerHTML = plaintextSegments();
encodedChunks.innerHTML = ciphertext();
output.innerHTML = normalizeCipherText();

Most of your code is constructed of very short methods.
Usually I'd consider a good practice, but in this case I think it just made the code less readable.
Additionally, I have to say that the HTML part wasn't necessary in terms of solving the issue - which was clearly Javascript/algorithm related.
This is my solution, which can be modified to match your context:
const input = "If man was meant to stay on the ground, god would have given us roots.";
const normalizedInput = input.replace(/[^\w]/g, "").toLowerCase();
const length = normalizedInput.length;
const cols = Math.ceil(Math.sqrt(length));
const rows = Math.ceil(length / cols);
var cypherText = "";
for (let i = 0; i < cols; i ++) {
for (let j = i; j < normalizedInput.length; j += cols) {
cypherText += normalizedInput[j];
}
cypherText += '\n';
}
console.log(cypherText);
This is what I came up with
const output = document.querySelector('#encoded_rectangle');
const encodedChunks = document.querySelector('#encoded_chunks');
const text = document.querySelector('#normalized_text');
const string = document.querySelector('#message');
const error = document.querySelector('#alert');
const encodeMessage = () => {
let message = string.value;
var normalisedText = message.replace(/[^a-zA-Z0-9]/g, "");
var textCount = normalisedText.length;
if (textCount < 50) {
console.log("Invalid message, Input more than one word and at Least 50 characters!");
return false;
}
var higest = Math.ceil(Math.sqrt(textCount));
var lowest = Math.ceil(textCount/higest);
var rect = [];
var coded = [];
var innerObj = {};
var resulting = "";
rect = rectangleSize(higest,lowest,normalisedText);
//read text from top-down i hotago!!!
coded = readFromTopDown(rect, higest);
coded.forEach(co => {
resulting += co.trim();
});
//nwa idi sharp, nice logic
console.log("Normalized: " + normalisedText);
console.log("Count: " + textCount);
console.log(rect);
console.log(coded);
console.log("Resulting: " + resulting);
function rectangleSize(higest, lowest, normalise) {
var rect = [];
var startIndex = 0;
for(var i = 0; i < lowest; i++){
if(i !== 0)
startIndex += higest;
if(normalise.substring(startIndex, startIndex + higest).length == higest){
rect.push(normalise.substring(startIndex, startIndex + higest))
}else{
//get the remainder as spaces
var spaces = higest - normalise.substring(startIndex, startIndex + higest).length;
var textI = normalise.substring(startIndex, startIndex + higest);
var str = textI + new Array(spaces + 1).join(' ');
rect.push(str);
}
}
return rect;
}
function readFromTopDown(rect, higest) {
var coded = [];
for(var i = 0; i < higest; i++){
var textMain = "";
rect.forEach(re => {
textMain += re.substring(i, i+1);
});
coded.push(textMain);
}
return coded;

I am new to RegExp and trying to learn capture groups in javascripts
I am using https://regex101.com/r/COYhIc/1 for testing
see attached image for character pos column of each match by https://regex101.com
Objective:
I want to print all matches and groups at console (Done)
I want to print character position of each match [see image](remaining)
JSFIDDLE: https://jsfiddle.net/bababalcksheep/p28fmdk4/68/
JavaScript:
function parseQuery(query) {
var isRE = query.match(/^\/(.*)\/([a-z]*)$/);
if (isRE) {
try {
query = new RegExp(isRE[1], isRE[2]);
} catch (e) {}
}
return query;
}
var str = $('#str').val();
var regex = parseQuery($('#reg').val());
//
var result;
var match_no = 0;
var output = '';
while ((result = regex.exec(str)) !== null) {
match_no++;
output += `\nMatch ${match_no}\n`;
output += `Full Match, ${ result[0]} , Pos\n`;
for (i = 1; i < result.length; i++) {
output += `Group ${i}, ${ result[i]} , Pos\n`;
}
}
console.log(output);
In your output field use index and lastIndex. exec returns an object with a index property.
output += `Full Match, ${ result[0]} , Pos ${result.index} - ${regex.lastIndex}\n `;
Update for the groups:
I have used a small logic to get the indices:
var m = new RegExp(result[i]);
output += `Group ${i}, ${ result[i]}, Pos ${$('#str').val().match(m).index} - ${regex.lastIndex} \n`;
function parseQuery(query) {
var isRE = query.match(/^\/(.*)\/([a-z]*)$/);
if (isRE) {
try {
query = new RegExp(isRE[1], isRE[2]);

According to docs RegExp.exec, you can retrieve it using index property. So I would add this line into your snippet to retrieve column position for your full match:
`${result.index}-${result.index + result[0].length}`
For subgroups, JS doesn't retrieve index, so a workaround can be achieved using indexOf:
const initialSubGroupIndex = str.indexOf(result[i], result.index);
`${initialSubGroupIndex}-${initialSubGroupIndex + result[i].length}`
I want to be able to enter a number into a text box and then on a button click generate that number of text boxes in another div tag and automatically assign the id
Something like this but not sure how to generate the text boxes and assign automatically assign the id
function textBox(selections) {
for (i=0; i < selections +1; i++) {
document.getElementById('divSelections').innerHTML = ("<form><input type="text" id="1" name=""><br></form>");
}
}
Try this one:
function textBox(selections){
selections = selections*1; // Convert to int
if( selections !== selections ) throw 'Invalid argument'; // Check NaN
var container = document.getElementById('divSelections'); //Cache container.
for(var i = 0; i <= selections; i++){
var tb = document.createElement('input');
tb.type = 'text';
tb.id = 'textBox_' + i; // Set id based on "i" value
container.appendChild(tb);
}
}
A simple approach, which allows for a number to be passed or for an input element to be used:
function appendInputs(num){
var target = document.getElementById('divSelections'),
form = document.createElement('form'),
input = document.createElement('input'),
tmp;
num = typeof num == 'undefined' ? parseInt(document.getElementById('number').value, 10) : num;
for (var i = 0; i < num; i++){
tmp = input.cloneNode();
tmp.id = 'input_' + (i+1);
tmp.name = '';
tmp.type = 'text';
tmp.placeholder = tmp.id;
form.appendChild(tmp);
}
target.appendChild(form);
}
Called by:
document.getElementById('create').addEventListener('click', function(e){
e.preventDefault();
appendInputs(); // no number passed in
});
JS Fiddle demo.
Called by:
document.getElementById('create').addEventListener('click', function(e){
e.preventDefault();
appendInputs(12);
});
JS Fiddle demo.
The above JavaScript is based on the following HTML:
<label>How many inputs to create:
<input id="number" type="number" value="1" min="0" step="1" max="100" />
</label>
<button id="create">Create inputs</button>
<div id="divSelections"></div>
See below code sample :
<asp:TextBox runat="server" ID="textNumber"></asp:TextBox>
<input type="button" value="Generate" onclick="textBox();" />
<div id="divSelections">
</div>
<script type="text/javascript">
function textBox() {
var number = parseInt(document.getElementById('<%=textNumber.ClientID%>').value);
for (var i = 0; i < number; i++) {
var existingSelection = document.getElementById('divSelections').innerHTML;
document.getElementById('divSelections').innerHTML = existingSelection + '<input type="text" id="text' + i + '" name=""><br>';
}
}
</script>
Note: Above code will generate the N number of textboxes based on the number provided in textbox.
It's not recommended to user innerHTML in a loop :
Use instead :
function textBox(selections) {
var html = '';
for (i=0; i < selections +1; i++) {
html += '<form><input type="text" id="'+i+'" name=""><br></form>';
}
document.getElementById('divSelections').innerHTML = html;
}
And be carefull with single and double quotes when you use strings
You have to change some code snippets while generating texboxes, Learn use of + concatenate operator, Check code below
function textBox(selections) {
for (var i=1; i <= selections; i++) {
document.getElementById('divSelections').innerHTML += '<input type="text" id="MytxBox' + i + '" name=""><br/>';
}
}
textBox(4); //Call function
JS Fiddle
Some points to taken care of:
1) In for loop declare i with var i
2) your selection + 1 isn't good practice at all, you can always deal with <= and < according to loop's staring variable value
3) += is to append your new HTML to existing HTML.
ID should be generate manually.
var inputName = 'divSelections_' + 'text';
for (i=0; i < selections +1; i++) {
document.getElementById('divSelections').innerHTML = ("<input type='text' id= " + (inputName+i) + " name=><br>");
}
edit : code formated
Instead of using innerHTML, I would suggest you to have the below structure
HTML:
<input type="text" id="id1" />
<button id="but" onclick="addTextBox(this)">click</button>
<div id="divsection"></div>
JS:
function addTextBox(ops) {
var no = document.getElementById('id1').value;
for (var i = 0; i < Number(no); i++) {
var text = document.createElement('input'); //create input tag
text.type = "text"; //mention the type of input
text.id = "input" + i; //add id to that tag
document.getElementById('divsection').appendChild(text); //append it
}
}

I have an issue to create dynamic fields with string count using JavaScript or jQuery.
Briefing
I want to create dynamic fields with the help of sting count, for example when I write some text on player textfield like this p1,p2,p3 they create three file fields on dynamicDiv or when I remove some text on player textfield like this p1,p2 in same time they create only two file fields that's all.
The whole scenario depend on keyup event
Code:
<script src="http://code.jquery.com/jquery-latest.js"></script>
<script>
function commasperatedCount(){
var cs_count = $('#player').val();
var fields = cs_count.split(/,/);
var fieldsCount = fields.length;
for(var i=1;i<=fieldsCount;i++){
var element = document.createElement("input");
element.setAttribute("type", 'file');
element.setAttribute("value", '');
element.setAttribute("name", 'file_'+i);
var foo = document.getElementById("dynamicDiv");
foo.appendChild(element);
}
}
</script>
