HTML - read .txt file from URL location in javascript - javascript

I want to read a .txt file an URL location, lets say from http://www.puzzlers.org/pub/wordlists/pocket.txt and process its content on my page.
Can you point me out some tutorials or some basic code on how to do this in javascript?
I have a basic HTML code where I have some tables and I want to populate them with text from a .txt from a given URL location, but I do not know how to read the data from that location.
<html>
<head>
<title>Pseudoganglia Interface</title>
<!-- CSS goes in the document HEAD or added to your external stylesheet -->
<style type="text/css">
table.gridtable {

}
table.gridtable th {
border-width: 1px;
padding: 8px;
border-style: solid;

table.gridtable td {

border-style: solid;
border-color: #666666;
background-color: #ffffff;
}
</style>
<!-- Table goes in the document BODY -->
<script>
function getText()
{
// read text from URL location
}
function populateTables() {
var tableHP = document.getElementById("tHP");
// Create an empty <tr> element and add it to the 1st position of the table:
var row = tableHP.insertRow(tableHP.rows.length);
// Insert new cells (<td> elements) at the 1st and 2nd position of the "new" <tr> element:
var cell1 = row.insertCell(0);
var cell2 = row.insertCell(1);
// Add some text to the new cells:
cell1.innerHTML = "NEW CELL1";
cell2.innerHTML = "NEW CELL2";
}
</script>
</head>
<body onload="populateTables()">
<table class="gridtable" id="tHP">
<tr>
<th colspan=2>HP</th>

<br>
<table class="gridtable" id="tIBM">
<tr>
<th colspan=2>IBM</th>

<tr>

</tr>
</table>
</body>
</html>

this code may help you:
function getText(){
// read text from URL location
var request = new XMLHttpRequest();
request.open('GET', 'http://www.puzzlers.org/pub/wordlists/pocket.txt', true);
request.send(null);
request.onreadystatechange = function () {
if (request.readyState === 4 && request.status === 200) {
var type = request.getResponseHeader('Content-Type');
if (type.indexOf("text") !== 1) {
return request.responseText;
}
}
}
}
function populateTables(){
var outer_text = getText();
outer_text = outer_text.split('\n'); // you can adjust the manner of parsing the received file (regexp)
var tableHP = document.getElementById("tHP");
// Create an empty <tr> element and add it to the 1st position of the table:
var row = tableHP.insertRow(tableHP.rows.length);
// Insert new cells (<td> elements) at the 1st and 2nd position of the "new" <tr> element:
var cell1 = row.insertCell(0);
var cell2 = row.insertCell(1);
// Add some text to the new cells:
cell1.innerHTML = outer_text[0];
cell2.innerHTML = outer_text[1];
}

from codegrepper using fetch (unsupported on IE).
const url = "http://www.puzzlers.org/pub/wordlists/pocket.txt"
fetch(url)
.then( r => r.text() )
.then( t => //process your text! )

Save content editable HTML table in multiple fields

I need to develop a HTML table where one of the table column is editable on its row and the table row is dynamic in term of the row number.
I come across a problem where when I automate the saveEdits() function, the code is not working.
Here is my code, where the 'cnt' is a dynamic numeric number. Example cnt=50
<!DOCTYPE html>
<html>
<head>
<style>
table {
font-family: arial, sans-serif;
border-collapse: collapse;
width: 100%;
}
table ,tr td{
border:1px solid #dddddd;
padding: 8px;
}
tbody {
display:block;
height:600px;
overflow:auto;
}
thead, tbody tr {
display:table;
width:100%;
table-layout:fixed;
}
thead {
width: calc( 100% - 1em )
}
tr:nth-child(even) {
background-color: #dddddd;
}
</style>
<script type="text/javascript">
function saveEdits(cnt) {
//get the editable elements.
var str_out = ''
while (cnt>0){
str1 = '\'edit' + cnt + '\': document.getElementById(\'edit' + cnt + '\').innerHTML,\n'
str_out = str_out.concat(' ', str1);
cnt--;
};
var editElems= { str_out };
alert(editElems)
//save the content to local storage. Stringify object as localstorage can only support string values
localStorage.setItem('userEdits', JSON.stringify(editElems));
}
function checkEdits(){
//find out if the user has previously saved edits
var userEdits = localStorage.getItem('userEdits');
alert(userEdits) // suppose to print {"edit1":" rpeyy7<br>","edit2":" tpruiiy<br>","edit3":" opty<br>"}
if(userEdits){
userEdits = JSON.parse(userEdits);
for(var elementId in userEdits){
document.getElementById(elementId).innerHTML = userEdits[elementId];
}
}
}
</script>
</head>
<body onload="checkEdits()">
<table id="myTable">
<thead>
<tr>
<td style="background-color:#A9A9A9" > Field#1 </td>
<td style="background-color:#A9A9A9" > Field#2 </td>
<td style="background-color:#A9A9A9" > Field#3- Each Row Under field#3 is content EditableByUser </td>
</tr>
</thead>
<tbody>
// Here is the python code that loop through a diectionary content
cnt = 0
for c in sorted(data_dict.keys()) :
cnt += 1
<tr>
<td> {0} </td> //Field#1
<td> {0} </td> //Field#2
...
...
<td id="edit{0}" contenteditable="true" onKeyUp="saveEdits({0});"> {1} </td>\n'.format(cnt,comment)]
</tr>
</table>
</body>
I'm not sure where goes wrong as when I automate the saveEdits() function with 'cnt' in while loop, the above code doesn't works for me. But when I defined each row clearly like below, the data the keyed-in are properly saved to each column.
function saveEdits(cnt) {
//get the editable elements.
var editElems = {
'edit1': document.getElementById('edit1').innerHTML,
'edit2': document.getElementById('edit2').innerHTML,
'edit3': document.getElementById('edit3').innerHTML,
};
alert(editElems) //print [object Object]
//save the content to local storage. Stringify object as localstorage can only support string values
localStorage.setItem('userEdits', JSON.stringify(editElems));
}
I would be much appreciate if someone can point out my mistake. The error is very much likely on saveEdits(cnt) function but I'm not sure how to fix that cause it I define each count 1 by 1, each update that being keyed-in is actually saved properly and able to retrieve when rerun. Thanks you!

Modal pops up after Ajax call completes instead of before or during

I am trying to get a modal popup to show "Please Wait" while an Ajax call is being made. The pop up occurs only after the call completes.
When I click my web link, everything is working, except the modal popup that is supposed to say "Please Wait" flashes for a split second AFTER the delay that the user is supposed to be asked to wait thru. That is, the modal pops up AFTER the Ajax call is completed instead of before.
When the page loads, it calls AjaxInitialUpdate. This works fine.
The issue is when you click the button that calls AjaxChangePassword.
The function is supposed to pull up a modal, then contact the web server, before finally removing the model and calling the AjaxInitialUpdate function to refresh the whole screen.
The issue is that the AjaxChangePassword modal doesn't pop up until the web query completes (by which time, there is no point in telling the user -- Please Wait).
Now, I am totally self-taught here, so I may be calling things by the wrong name or terms. I welcome any ideas to make it run better, but please be detailed, I'm still very novice in Java.
Also, the last time I did any kind of HTML programming was before Style sheets were the way to go, so I'm kind of having to learn them as well (and refresh on all the rest, so please explain any answer in detail).
Lastly, the server side of this is written in Powershell and is single threaded so I am trying to put as much in the HTML file as possible instead of calling secondary files, like style sheets and images.

When I call AjaxChangePassword(), I expected the modal to open BEFORE the query.
As it is now, if I stop the server after the page loads, but before this function is started, the modal never pops up, then once I start the server side back up, and I see the query come in and get answers, only then does it pop up, and then only for a split second.
What am I doing wrong in the way I am calling it?
As I reviewed your code and found that in the function AjaxChangePassword firstly you opened modal and then called ajax then closed modal the problem is that basically javascript executes synchronously but if there is ajax call then it executes asynchronously, so according to that your modal opens and then call ajax untill ajax is busy in getting response before that next line will be executed that line is for modal close and this happens in the fraction of ms so you don't see anything, And you said that after ajax call modal is showing because in AjaxChangePassword the call back method is AjaxInitialUpdate and also in this method you opened modal then closed but remember in this method you closed modal in the call back method so it appears for some time and you can see so according to me just remove
document.getElementById('myModal1').style.display = "none";
this line from AjaxChangePassword method below is corrected AjaxChangePassword function
function AjaxChangePassword(){
document.getElementById('myModal1').style.display = "block";
document.getElementById('myModal2').style.display = "none"; // Make sure its not poped up..
// we need to set item on the modal to explain what we are doing...
document.getElementById("ModalTextLine1").innerHTML="Processing password change request. Please Wait"
var xhr = "";
var xhr = new XMLHttpRequest();
// server will check if values are valid..
var Server = document.getElementById("DynServerName").innerHTML;
var AdminID = document.getElementById("DynAdminID").innerHTML;
xhr.open('GET', 'http://PSShellSrv.mydomain.local:80/CyberPass3/?command=update&sub=change&server=' + Server + '/' + AdminID+'&NoCache=' + ((new Date()).getTime()), true);
xhr.responseType = 'text';
xhr.onload = function () {
console.log('Initail Comment Response onpassword change.');
if (xhr.readyState === xhr.DONE) {
if (xhr.status === 200) {
document.getElementById('myModal1').style.display = "none";
console.log(xhr.response);
console.log("Report password changed.");
AjaxInitialUpdate() // password changed, lets refresh.
};
};
};
xhr.send(null);
};
and check. I may be wrong but check it.

Javascript sorting a csv rows and displaying in table

I have a csv file which has this format:
Major;2;4;29
Major should be displayed on the 4 row 2 column.
The file can have a lot nof rows!
I have created this:
var fileInput = document.getElementById("csv"),
readFile = function () {
var reader = new FileReader();
reader.onload = function () {
document.getElementById('out').innerHTML = reader.result;
};
reader.readAsBinaryString(fileInput.files[0]);
};
fileInput.addEventListener('change', readFile);
<style type="text/css">
output {
display: block;
margin-top: 4em;
font-family: monospace;
font-size: .8em;
}
</style>
which basically takes a csv file as an input and prints all as it is raw!How can I work and divide the rows on the ";"?And I also want an honest answer what level is this for?(intern,senior?)
Here's a trivial example, it's fairly straight forward. The issue will be splitting the data, it's pretty simple if the data is simple and the delimiter unique. But if the delimiter is in the data, the splitting into values requires a little more cleverness.
This uses table.rows to get the row, then row.cells to get the cell and inserts the value. Columns and rows are zero indexed, and for rows includes the header and footer (if they exist). You can also use the tbody.rows if the header rows should be skipped.
var data = 'Major;1;2;29\nMinor;2;3;29';
function insertData(id, data) {
// Show data
console.log(data);
// Get the table
var table = document.getElementById(id);
// Split the data into records
var dataRows = data.split(/\n/);
// Split each row into values and insert in table
if (table) {
dataRows.forEach(function(s) {
var x = s.split(';');
table.rows[x[2]].cells[x[1]].textContent = x[0];
});
}
}
table {
border-collapse: collapse;
border-left: 1px solid #999999;
border-top: 1px solid #999999;
}
td, th {
border-right: 1px solid #999999;
border-bottom: 1px solid #999999;
}
<table id="t0">
<thead>
<tr>
<th>col 0<th>col 1<th>col 2
</thead>
<tbody>
<tr>
<td> <td><td>
<tr>
<td> <td><td>
<tr>
<td> <td><td>
</tbody>
</table>
<button onclick="insertData('t0', data)">Insert data</button>

Random Color for <tr>

So overall I am trying to make the boxes change color when someone puts a mouse over them. Color has to be random. I know I am missing a connection point between my functions but I cant figure out what it is.
<!DOCTYPE html>
<html onmousedown='event.preventDefault();'
onmouseenter = "colorize();"
>
<head>
<title> Boxes </title>
<meta charset='utf-8'>
<style>
table {
border-spacing: 6px;
border: 1px rgb(#CCC);
margin-top: .5in;
margin-left: 1in;
}
td {
width: 40px; height: 40px;
border: 1px solid black;
cursor: pointer;
}
</style>
<script>
Create a function called colorize that is passed an element object as its
parameter and sets the elements background color style property using the
rgb(r,g,b) method setting each r,g and b to a random number between 0 and
255.
function colorize() {
var
r = ('0'+(Math.random()*255|0).toString(16)).slice(-2),
g = ('0'+(Math.random()*255|0).toString(16)).slice(-2),
b = ('0'+(Math.random()*255|0).toString(16)).slice(-2);
return '#' +r+g+b;
}
function colorize(co) {
document.body.style.background = co;
}
</script>
</head>
<body>
<table>
<tbody>
<script type="text/javascript">
Use document.write() and for-loops to fill in the table to create a 16x16 box table. For each td element, create a onmouseenter call to colorize, passing it the element itself (this).
var row = 16;
var cols = 16;
for(var r=0;r<row;r++){
document.write("</tr>");
for(var c=0;c<cols;c++){
document.write("<td></td>");
}
document.write("</tr>");
}
</script>
</tbody>
</table>
</body>
</html>
I'm not sure what you wanted to do with body background, nothing said about that in your text. ALos your colorizer func is overwritten. maybe you wanted something like this... ?
<!DOCTYPE html>
<html>
<head>
<title> Boxes </title>
<meta charset='utf-8'>
<style>
table {
border-spacing: 6px;
border: 1px rgb(#CCC);
margin-top: .5in;
margin-left: 1in;
}
td {
width: 40px; height: 40px;
border: 1px solid black;
cursor: pointer;
}
</style>
<script>
function colorize(el) {
var r = ('0'+(Math.random()*255|0).toString(16)).slice(-2),
g = ('0'+(Math.random()*255|0).toString(16)).slice(-2),
b = ('0'+(Math.random()*255|0).toString(16)).slice(-2);
el.style.backgroundColor = '#' +r+g+b;
}
</script>
</head>
<body>
<table>
<tbody>
<script type="text/javascript">
var row = 16;
var cols = 16;
for(var r=0;r<row;r++){
document.write("</tr>");
for(var c=0;c<cols;c++){
document.write("<td onMouseEnter='colorize(this);'></td>");
}
document.write("</tr>");
}
</script>
</tbody>
</table>
</body>
</html>
You need to have your colorize function update each cell in your table. Replace both colorize() and colorize(co) with one function:
function colorize() {
var r = ('0'+(Math.random()*255|0).toString(16)).slice(-2),
g = ('0'+(Math.random()*255|0).toString(16)).slice(-2),
b = ('0'+(Math.random()*255|0).toString(16)).slice(-2);
for (var i = 0; i < document.getElementsByTagName("td").length; i++){
document.getElementsByTagName("td")[i].style.backgroundColor = "#"+r+g+b;
}
}
i play with Ids and adding onmousedown in html tag that calls the func.
function colorize() {
var
r = ('0'+(Math.random()*255|0).toString(16)).slice(-2),
g = ('0'+(Math.random()*255|0).toString(16)).slice(-2),
b = ('0'+(Math.random()*255|0).toString(16)).slice(-2);
return '#' +r+g+b;
}
function change(){
var x = document.getElementById("1");
var y = document.getElementById("2");
x.style.color = colorize();
y.style.color = colorize();
}
<table frame="box" onmousedown="change()"id="1" >
<tr>
<th>Month</th>
<th>Savings</th>
</tr>
<tr>
<td>January</td>
<td>$100</td>
</tr>
</table>
<table frame="box" onmousedown="change()" id="2" >
<tr>
<th>Month</th>
<th>Savings</th>
</tr>
<tr>
<td>February</td>
<td>$200</td>
</tr>
</table>

Hide column while exporting to excel from html table using javascript

I have a html table which I have to export to excel , but while doing so, I dont want some of the td elements to be exported. When I apply javascript to hide the td, the changes are being applied only to the view form and not to the the content being exported.
Need help in how to export in this case.
I have included html, css and script all in one page.
<html>
<body>
<div id="myDiv">
<table id="metrics" border="1px" cellspacing="0 px" style="border-style: solid; border-color: Black;
border-width: thin;">
<tr>
<td style= "background-color: #bfbfbf; font-size: small; color: black;">
LOB
</td>
<td>
<span class="hillbillyForm" data-displayname='LOB' style="display:none;"></span>
</td>
</tr>
</table>
<input type="button" id="btnExport" value="Export" onclick="TableToExcel('metrics');" />
</div>
</body>
Here I want to hide the td which contains span class "hillbillyForm"
The javascript That I am using is
function TableToExcel(tableid) {
var id = $('[id$="' + tableid + '"]');
var $clonedTable = $("id").clone();
$clonedTable.find('[style = "display: none"]').remove();
var strCopy = $('<div></div>').html(id.clone()).html();
window.clipboardData.setData("Text", strCopy);
var objExcel = new ActiveXObject("Excel.Application");
objExcel.visible = false; var objWorkbook = objExcel.Workbooks.Add; var objWorksheet = objWorkbook.Worksheets(1); objWorksheet.Paste; objExcel.visible = true;
}
</script>
So what I'm understanding is that you want to remove all TD's which have a direct child with the class hillbillyForm.
You can do something like this:
var form = document.getElementById(tableid),
exportForm = form.cloneNode(true),
elementsToRemove = exportForm.querySelectorAll('.hillbillyForm');
for (var i = elementsToRemove.length; i--;){
var td = elementsToRemove[i].parentElement;
if (td) td.parentElement.removeChild(td);
}
