All javascript functions coming up undefined from html

All javascript functions coming up undefined from html - javascript

I had majority of these functions working and now when i restarted my program they are saying undefined functions through chrome. Not sure the exact problem, im sure im missing something somewhere but its not coming up through eclipse. REALLY NEED HELP !!!! cant figure out the exact location or i would have shortened the files but i felt more is better than less in this instance where i cant find out where the code is breaking. Thank you all

Not sure the exact problem, im sure im missing something somewhere but its not coming up through eclipse. REALLY NEED HELP !!!! cant figure out the exact location or i would have shortened the files but i felt more is better than less in this instance where i cant find out where the code is breaking. Thank you all

You have an error in your code that i pointed,
You have defined function and ended it using ;
function addToGroupServlet(email);
change above to
function addToGroupServlet(email)

move your:
<script src="./JS/managerMenu.js"></script> tags to the <head> section

you have ended function by ;
function addToGroupServlet(email){
//....
}

`I'm doing a program with 3 different html pages to search the data using Json link. I have 3 radio buttons which will be called on change to 3 separate html pages on my home html.

Dynamically generated table with checkbox overflowing the parent div element

I am trying to create a table dynamically using javascript. I want each table to have a checkbox beside it. So, I have written the following code:
JAVASCRIPT
label_submit_btn.addEventListener("click", function(event){
event.preventDefault();
var formInputs = document.getElementById("label_query_form").querySelectorAll("input");
validation = validateForm(formInputs);
if(validation[0]){
var label_query_form_action = document.getElementById("label_query_form").getAttribute("action");
var label_val = document.getElementById("label_no")
query_db("label_data_div", label_query_form_action, label_val, true, "label_query_row");
// var chk_boxes = document.getElementsByClassName("form-check-input");
// document.getElementById("data_delete_btn").disabled = false;
}
else{
alert(validation[1])
}
});
function query_db(output_div, form_action, form_data, add_checkbox, row_class){
document.getElementById(output_div).innerHTML = ""
var xhr = new XMLHttpRequest();
var formData = new FormData();
formData.append(form_data.name, form_data.value)
xhr.onreadystatechange = function(){
if(this.readyState == 4 && this.status == 200){
let response_data = JSON.parse(this.responseText);
let table_data = JSON.parse(response_data);
table_data = create_table_from_json(table_data, add_checkbox, row_class);
document.getElementById(output_div).innerHTML += table_data;
}
}
xhr.open("POST", form_action, true);
xhr.send(formData);
}
function create_table_from_json(table_data, add_checkbox, row_class){
var table_rows = "";
for (var i = 0; i < table_data["columns"].length; i++) {
table_rows += "<th>" + table_data["columns"][i] + "</th>";
}
table_rows += "<th>Select</th>";
console.log(table_rows);
table_rows = "<tr>" + table_rows +"</tr>";
for (var i = 0; i < table_data["data"].length; i++) {
trow = ""
for (var j = 0; j < table_data["columns"].length; j++) {
trow += "<td class="+ table_data["columns"][j] +">" + table_data["data"][i][j] + "</td>";
}
if(add_checkbox == true){
trow += '<td><input type="checkbox" class="form-check-input"/> </td>';
}
table_rows += "<tr class="+ row_class + ">" + trow +"</tr>";
}
return "<table><tbody>" + table_rows + "</table></tbody>";
}

Now, while rendering the page, all of the checkboxes are overflowing outside of the div element(see image).

I'm supposed to auto-generate the table based on the data available from my main.js script which is in JSon format. There is no problem with the data loading since the data can be display in my html file. However, the problem comes whn my data is returned undefined on my auto generated table whn i click the 'add' button to update the data in the table. Whn i click in the edit button, the data is get correctly. only whn the display, it returns me undefined.

i know how alrdy.
here i attach the code & sample of the data i hv done.

Create array from Dynamic table

How can I create an array from this table/form? The onclick function formData() from the dynamic table only returns a concatenated string. I need to create an associative array in JSON using the 'device' variable as key, however I'll settle for any sort of array at all. Clearly, I'm not very good at this...
function createInputTable()
{
var num_rows = document.getElementById('rows').value;
var tableName = document.getElementById('conn_input_device').value;
var column_number = 2;
var tdefine = '<form id="form"><table id="table" border = "1">\n';
var theader = '<tr><th>No</th><th>Input</th><th>Output</th></tr>\n';
var caption = '<caption><input id="device" value ="' + tableName + '" /></caption>';
var tbody = '';
var tfooter = '</table>';
var createNewDevice = '<button onclick="formData();">Form Data</button></form>'
var i = 0;
for (var i= 0; i < num_rows; i++)
{
tbody += '<tr><td>' + (i+1) + '</td><td><input class="cell" id="i'+ i + '" type = "text"/></td>';
tbody += '<td><input class="cell" id="o'+ i + '" type="text"/></td></tr>\n';
}
document.getElementById('wrapper').innerHTML = caption + tdefine + theader + tbody + tfooter + createNewDevice;
}
function formData()
{
var cellData = document.getElementById("form");
//var device = document.getElementById('device').value;
//var j;
var obj = [];
for(j=0; j< cellData.length; j++)
{
obj += cellData[j].value;
}
var json = JSON.stringify(obj);
alert (json);
//document.getElementById('result').innerHTML = json;
}
<form id="tableGen" name="table_gen">
<label>Connecting device: <input type = "text" name = "conn_input_device" id = "conn_input_device"/></label><br />
<label>Number of inputs: <input type="text" name="rows" id="rows"/></label><br />
<input name="generate" type="button" value="Create Input Table!" onclick='createInputTable();'/>
</form>
<div id="wrapper"></div>

1) This my answer how do this on VueJS and jQuery
2) Vanilla js - CODEPEN - DEMO
// Get DOM elements
const $el = [
'#tmpl',
'#user-count',
'#people-count',
'#form-items',
'#btn-add',
'#form',
].reduce((res, item) => {
const method = item.startsWith('#')
? 'querySelector'
: 'querySelectorAll'
const key = item
.replace(/\W/ig, ' ').trim()
.replace(/\s+\w/g, v => v.trim().toUpperCase())
res[key] = document[method](item)
return res
}, {})
// Variable for dynamic template
const tmpl = $el.tmpl.innerHTML.trim()
// Click on Add new button
$el.btnAdd.addEventListener('click', () => {
const peopleCount = +$el.peopleCount.value
const html = Array(peopleCount)
.fill(tmpl)
.join('')
$el.formItems.insertAdjacentHTML('beforeend', html)
})
// Submit form
$el.form.addEventListener('submit', e => {
e.preventDefault()
alert('Submit form by ajax or remove this method for default behavior')
})
// Add form click (it's need for dynamic handler on child elements)
$el.form.addEventListener('click', e => {
// Delete behaviors
if (e.target.classList.contains('btn-del') && confirm('Are you sure?')) {
e.target.closest('.row').remove()
}
})
<div id="app">
<div>
<div>
<button id="btn-add">Add new user</button>
<label>Number of People:</label>
<input type="number" id="people-count" value="1" min="1">
</div>
<form id="form">
<div id="form-items" data-empty="Users list is empty"></div>

I have edited your code,
function createInputTable()
{
var num_rows = document.getElementById('rows').value;
var tableName = document.getElementById('conn_input_device').value;
var column_number = 2;
var tdefine = '<form id="form"><table id="table" border = "1">\n';
var theader = '<tr><th>No</th><th>Input</th><th>Output</th></tr>\n';
var caption = '<caption><input id="device" value ="' + tableName + '" /></caption>';
var tbody = '';
var tfooter = '</table>';
var createNewDevice = '<button onclick="formData();">Form Data</button></form>'
var i = 0;
for (var i= 0; i < num_rows; i++)
{
tbody += '<tr><td>' + (i+1) + '</td><td><input class="cell" id="i'+ i + '" type = "text"/></td>';
tbody += '<td><input class="cell" id="o'+ i + '" type="text"/></td></tr>\n';
}
document.getElementById('wrapper').innerHTML = caption + tdefine + theader + tbody + tfooter + createNewDevice;
}
function formData()
{
var cellData = document.getElementsByTagName("tr");
var obj = [];
for(var i=0;i<cellData.length-1;i++){
obj.push(document.getElementById("i"+i).value);
obj.push(document.getElementById("o"+i).value);
}
alert(JSON.stringify(obj));
}
<form id="tableGen" name="table_gen">
<label>Connecting device: <input type = "text" name = "conn_input_device" id = "conn_input_device"/></label><br />
<label>Number of inputs: <input type="text" name="rows" id="rows"/></label><br />
<input name="generate" type="button" value="Create Input Table!" onclick='createInputTable();'/>
</form>

Show table with fetched json data on a button click

I am trying to fetch the json data fetched from a web service. I've fetched data successfully but I want to show it in a table form only after a button click.
The following code shows the name of table rows when the page is load.It should only appear after a button click.
Code:
<html>
<head>
<script language="javascript" type="text/javascript">
var request = null;
function createRequest()
{
try {
request = new XMLHttpRequest();
}
catch (trymicrosoft)
{
try {
request = new ActiveXObject("MsXML2.XMLHTTP");
}
catch (othermicrosoft)
{
try {
request = new ActiveXObject("Microsoft.XMLHTTP");
}
catch (failed) {
request = null;
}
}
}
if (request == null)
alert("Error creating request object!");
}
function getMessage(lat,lon)
{
alert(lat);
createRequest();
;
var dis = document.getElementById("dt_id").value;
var url = "http://localhost:8080/testrestfullapi/webresources/drugController/getdata/"+dis;
alert(url);
request.open("GET", url, true);
request.onreadystatechange = handleResponse;
request.send(null);
}
function handleResponse()
{
if (request.readyState == 4){
alert("readystate=4");
var check=request.status;
alert(check);
alert(request.responseText);
if(check.toString()=="200")
alert("status ok");
var det = eval("(" + request.responseText + ")");
alert(det);
var data = "";
var i = 0;
for (var property in det) {
alert("Entered in for loop");
if (Object.prototype.hasOwnProperty.call(det, property)) {
data = data + "<tr>";
data = data + "<td class=\"sorting_1\">" + det[i].disease + "</td>";
data = data + "<td class=\" sorting_1\">" + det[i].drug + "</td>";
data = data + "<td class=\" sorting_1\">" + det[i].trade + "</td>";
i++;
}
}
document.getElementById("table_data").innerHTML = data;
}
}
</script>
</head>
<body>
<div style="text-align:left; margin:8px 5px auto;">
<label for="dt_id">Please enter disease </label>
<input type="Text" id="dt_id" maxlength="25" size="25"/>
<input type='button' onclick='getMessage()' value='SUBMIT'>
</div>
<table>
<thead>
<tr role="row">
<th>Disease</th>
<th>Drug</th>
<th>Trade</th>
</tr>
</thead>
<tbody id="table_data">
</tbody>
</table>
</body>
</html>

You forgot to hide the table initially. Hide the table by using this attribute style="display:none;" .. Then in button click you can show the table when you want...
