JQUERY dynamically created table. Trying to hide entire column

This is creating my table and working - It creates a table and I am going to have it check a list to hide columns. For testing purposes I am trying to hide the colun "Proj_Type" it does hide the header but does not hide the actual column of data. I want the entire thing to hide.
function createTab(Name, id) {
var $button = $('<button/>', {
'class': 'tablinks',
'onclick': 'return false;',
'id': name,
text: Name,
click: function () {
return false;
}
});
var $div = $('<div>').prop({
id: Name,
'name': id + 'MKTTAB',
className: 'tabcontent'
})
var $table = $('<table/>', {
'class': 'GRD1',
id: id + "GRDMKTLIST",
}
)
$table.append('<caption>' + Name + '</caption>')
var $tbody = $table.append('<tbody />').children('tbody');
$tbody.append('<tr />').children('tr:last');
$.ajax({
type: "POST",
url: "../WebMethods/MarketPersuitMethods.aspx/GetQueryInfo",
data: {},
contentType: "application/json; charset=utf-8",
dataType: 'json',
async: false,
success: function (d) {
var data = $.parseJSON(d.d);
var colHeader = Object.keys(data[0]);
for (var i = 0; i < colHeader.length; i++) {
if (colHeader[i] != "notes") {
$tbody.append("<th>" + colHeader[i] + "</th>");
}
}
//sets new line
$tbody.append('<tr />').children('tr:last')
for (var i = 0; i < data.length; i++) {
for (var j = 0; j < colHeader.length; j++) {
if (colHeader[j] != "notes") {
$tbody.append('<td>' + data[i][colHeader[j]] + '</td>');
}
}
$tbody.append('<tr />').children('tr:last')
}
setTimeout(function () {
}, 1000);
}
});
$($table.find('th')).each(function () {
var indextest = $(this).index() + 1;
if ($(this).text() == "Proj_Type") {
$('[id*=GRDMKTLIST] td:nth-child(' + indextest + '),th:nth-child(' + indextest + ')').hide();
}
})
$button.appendTo('#tabs');
$table.appendTo($div);
$div.appendTo('#TabbedMktList');
}
However, on the bottom where i have
if ($(this).text() == "Proj_Type") {
$('[id*=GRDMKTLIST] td:nth-child(' + indextest + '),th:nth-child(' + indextest + ')').hide();
}
This only hides the header and I am trying to hide the entire column TD included.

There are two main issues:
$('[id*=GRDMKTLIST]
will look in the DOM, but your $table has not yet been added to the DOM, so does nothing. Use $table.find(... to use the $table variable in memory.
$tbody.append('<td
will append the td (and equivalent code for th) to the tbody - but these should be in a tr.
The browser will do some "magic" and see an empty <tr></tr> and put a new row in for you, but selectors for tbody > tr > td won't work. This also means there's only a single :nth-child(n) per n, not per row (as all cells across all rows are siblings).
You can add a new row to $tbody and return the new row by using .appendTo
$tr = $("<tr>").appendTo($tbody);
then add the th/td to $tr and not $tbody
$tr.append('<td...`
Regarding the selector for $table.find("td,th") you don't need the th part as you're looping th and it's already this, so you can do:
$(this).hide();
$table.find('td:nth-child(' + indextest + ')').hide();
Also make sure you only create tr as you need it. Your code create a tr before the data row loop and inside the data row loop, leaving an empty tr.
for (var i = 0; i < data.length; i++) {
$tr = $("<tr>").appendTo($tbody);
for (var j = 0; j < colHeader.length; j++) {
if (colHeader[j] != "notes") {
$tr.append('<td id=' + colHeader[j] + '>' + data[i][colHeader[j]] + '</td>');
}
}
}

how do i get the total count of rows in a Json

I have JSON data like this:
[0:{name:"jason",height:"150cm"},
1:{name:"henry",height:"178cm"}]
I'm trying to do a for loop in my function, which is
function DrawTable(output) {
var general = output;
var sb = new StringBuilder();
for (var i = 0; i < *total row in the json*; i++)
sb.append("<td>" + general[0][i]["name"] + "</td>");
sb.append("<td>" + general[0][i]["height"] + "</td>");
}
I don't know the way to do it..

First off: that data isn't JSON.
For the sake of argument, let's pretend it was formatted as such:
[{
"name": "jason",
"height": "150cm"
}, {
"name": "henry",
"height": "178cm"
}]
Which would be valid JSON.
You could then do something more like this:
If using jQuery:
function DrawTable(jsonString) {
var stuff = JSON.parse(jsonString);
var table = createElement('table')
.append(
createElement('thead')
.append(
createElement('tr')
.append(
createElement('th').text('Name'),
createElement('th').text('Height')
)
)
);
var body = createElement('tbody');
stuff.forEach(function(item) {
body
.append(
createElement('tr')
.append(
createElement('td').text(item.name),
createElement('td').text(item.height)
)
);
});
//append body to table and show on page somewhere
}
Or, based on your existing code:
function DrawTable(output) {
var general = JSON.parse(output);
var sb = new StringBuilder();
for (var i = 0; i < general.length; i++) {
sb.append("<td>" + general[i].name + "</td>");
sb.append("<td>" + general[i].height + "</td>");
}
}

If your data happens to be formatted like:
{
0: {name:"jason",height:"150cm"},
1: {name:"henry",height:"178cm"}
}
instead of wrapped in an array. Then looping through Objects.values(yourData) might be what you are looking for:
function DrawTable(objectsData) {
var htmlString = '';
Object.values(objectsData).forEach((object) => {
htmlString += "<td>" + object.name + "</td>";
htmlString += "<td>" + object.height + "</td>";
});
return htmlString;
}

Select table cell as a group

In this table, I want to select multiple cells as a group.
You can select a target cell by clicking on it,
but I also want to click and drag to cover multiple cells as a group.
Is that possible to achieve that without any plugins (just use JQuery)?
This is what I want to achieve:
The array content will be:
["3-2", "3-3", "4-2", "4-3", "5-2", "5-3"]
Here is what I try so far:
var group = [];
var columnIndex = 7,
rowIndex = 10;
var $tableContainer = $('#tablecontainer'),
$table = $tableContainer.append('<table border="1" id="table1"></table>'),
$thead = $table.find('table').append('<thead></thead>'),
$tbody = $table.find('table').append('<tbody></tbody>');
var $columnNumber = "";
var $tdNumber = "";
for (var col = 1; col <= columnIndex; col++) {
$columnNumber += "<th>Column " + col + "</th>";
$tdNumber += "<td style='text-align: center; vertical-align: middle; color:red'></td>";
}
$thead = $thead.append('<tr><th>0</th>' + $columnNumber + '</tr>');
for (var row = 1; row <= rowIndex; row++) {
$tbody = $tbody.append('<tr><td>Row ' + row + '</td>' + $tdNumber + '</tr>');
}
$('#table1 > tbody > tr > td').hover(function() {
var colIndex = $(this).parent().children().index($(this));
var rowIndex = $(this).parent().parent().children().index($(this).parent());
$(this).attr("title", 'Row: ' + rowIndex + ', Column: ' + colIndex);
// console.log('Row: ' + rowIndex + ', Column: ' + colIndex);
});
$('#table1 > tbody > tr > td').click(function() {
var colIndex = $(this).parent().children().index($(this));
var rowIndex = $(this).parent().parent().children().index($(this).parent());
group.push(rowIndex + "-" + colIndex);
console.log(group);
$(this).css("background-color", "red");
// console.log('Row: ' + rowIndex + ', Column: ' + colIndex);
});
#table1>tbody>tr>td:hover {
background: red;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="tablecontainer"></div>
Any help would be appreciated!

The functionality you want to achieve is possible by using jquery mouseover function.
I made a fiddle to get the desired output as you expect.

Hope this helps you in solving the issue.

creating a html table in javascript

I want to create HTML table in java script. Inside a for loop I want to create a dynamic table which can be extended. This is how I am it using now:
function(json)
{
var content= $('#name1').html('').append('<td> Name: ' + json.name + '<td>');
var content= $('#address1').html('').append('<td> address: ' + json.address + '<td>');
var content= $('#age1').html('').append('<td> age: ' + json.age + '<td>');
var content= $('#status1').html('').append('<td> status: ' + json.status + '<td>');
}
HTML file is
<table>
<tr id="name1"></tr>
<tr id="address1"></tr>
<tr id="age1"></tr>
<tr id="status1"></tr>
</table>
now it is just with hardcore values but I want it auto generated and insert more rows if neccessary...

remove id from tr. Because if you need multiple row then id will be duplicated which is not valid.
<table id="mytable">
</table>
function(json)
{
for(i=0;i<json.length;i++){
var newRow= $("<tr></tr>");
newRow.append('<td> Name: ' + json[i].name + '<td>');
newRow.append('<td> address: ' + json[i].address + '<td>');
newRow.append('<td> age: ' + json[i].age + '<td>');
newRow.append('<td> status: ' + json[i].status + '<td>');
$("#mytable").append(newRow);
}
}

i think this will help you
function(json)
{
for(i=0;i<jsn.length;i++){
$('#YOUR_TABLE_ID').append("<tr><td>"+ json.name+"</td></tr>")
}
}

<table id="mytable">
<tr id="name1"><td></td></tr>
</table>
if (results != null && results.length > 0) {
// Build our table header
var content = "";
for(i=0;i<data.length;i++)
{
content += '<tr>';
content += '<td></td>'
}
content += '</tr>';
}
$("#mytable tbody").append(content);
}

You can Use Append Method to create Rows in a table like
for(i=0;i<data.length;i++)
{
$("YOUR_TABLE_ID").append("<tr><td>"+data[i]['name']+"</td><td>"+data[i]['address']+"</td><td>"+data[i]['age']+"</td><td>"+data[i]['status']+"</td></tr>");
}

I'm not clear with your requirement but i can provide you some basic code hope that helps you.
var jsonList = [{name:'Jhon',address:'Jhon Address goes here',age:'27',status:'Single'},
{name:'Smith',address:'Smith Address goes here' ,age:'32', status:'Single' }];
function createTable(){
var table = '<table>';
for(var ind=0;ind< jsonList.length;ind++)
table += fetchRowInformation(jsonList[ind]);
console.log(table+'</table>');
}
function fetchRowInformation(json){
return '<tr><td> Name: ' + json.name + '<td>'+'<td> address: ' + json.address + '<td>'+ '<td> age: ' + json.age + '<td>'+'<td> status: ' + json.status + '<td></tr>';
}
JS Fiddle Demo

function tableCreate(rows, columns) {
var body = document.body
tbl = document.createElement('table');
tbl.style.width = '20%';
tbl.style.border = '1px solid black';
for (var i = 0; i < rows; i++) {
var tr = tbl.insertRow();
for (var j = 0; j < columns; j++) {
var td = tr.insertCell();
td.appendChild(document.createTextNode('Cell'));
td.style.border = '1px solid black';
}
}
tbl.style.marginTop = '10px'
tbl.style.borderCollapse = 'collapse'
td.style.padding = '2px'
body.appendChild(tbl);
}
tableCreate(15, 10);

get text from attribute and format it

I have a div elements with data-seat and data-row property:
<div class='selected' data-seat='1' data-row='1'></div>
<div class='selected' data-seat='2' data-row='1'></div>
<div class='selected' data-seat='3' data-row='1'></div>
<div class='selected' data-seat='1' data-row='2'></div>
<div class='selected' data-seat='2' data-row='2'></div>
I want print friendly message for selected seats:
var selectedPlaceTextFormated ='';
$(".selected").each(function () {
var selectedPlace = $(this);
selectedPlaceTextFormated += "Row " + selectedPlace.attr("data-row") + " (seat " + selectedPlace.attr("data-seat") + ")\n";
});
alert(selectedPlaceTextFormated);
This code works well and shows the following:
Row 1 (seat 1)
Row 1 (seat 2)
Row 1 (seat 3)
Row 2 (seat 1)
Row 2 (seat 2)
But, I want group seats by row, i.e I want the following:
Row 1(seats: 1,2,3)
Row 2(seats: 1,2)
also, order by row number. How can I do this?
Thanks. DEMO

Here is the code
var selectedPlaceTextFormated ='';
var row_array = [];
$(".selected").each(function () {
var selectedPlace = $(this);
if (!row_array[selectedPlace.attr("data-row")]){
row_array[selectedPlace.attr("data-row")] = selectedPlace.attr("data-seat");
}
else row_array[selectedPlace.attr("data-row")] += ','+selectedPlace.attr("data-seat");
});
for (row in row_array){
alert("Row "+ row +"(seat " + row_array[row] + ")\n" );
}
And here the link to the working fiddle: http://jsfiddle.net/3gVHg/

First of all, jQuery is kind enough to automatically grab data- attributes into its data expando object, that means, you can access those data via:
jQueryObject.data('seat');
for instance.
Your actual question could get solved like
var $selected = $('.selected'),
availableRows = [ ],
selectedPlaceTextFormated = '',
currentRow,
currentSeats;
$selected.each(function(_, node) {
if( availableRows.indexOf( currentRow = $(node).data('row') ) === -1 ) {
availableRows.push( currentRow );
}
});
availableRows.forEach(function( row ) {
selectedPlaceTextFormated += 'Row ' + row + '(';
currentSeats = $selected.filter('[data-row=' + row + ']').map(function(_, node) {
return $(this).data('seat');
}).get();
selectedPlaceTextFormated += currentSeats.join(',') + ')\n';
});
jsFiddle: http://jsfiddle.net/gJFJW/3/

You need to use another variable to store the row, and format accordingly.
var selectedPlaceTextFormated ='';
var prevRow = 0;
$(".selected").each(function () {
var selectedPlace = $(this);
var row = selectedPlace.attr("data-row");
var seat = selectedPlace.attr("data-seat");
if(prevRow == row){
selectedPlaceTextFormated += "," + seat;
}
else{
if(selectedPlaceTextFormated != ''){
selectedPlaceTextFormated += ')\n';
}
selectedPlaceTextFormated += "Row " + row + " (seat " + seat;
prevRow = row;
}
});
selectedPlaceTextFormated += ')\n';
alert(selectedPlaceTextFormated);
Check http://jsfiddle.net/nsjithin/R8HHC/

This can be achieved with a few slight modifications to your existing code to use arrays; these arrays are then used to build a string:
var selectedPlaceTextFormated = [];
var textFormatted = '';
$(".selected").each(function(i) {
var selectedPlace = $(this);
var arr = [];
selectedPlaceTextFormated[selectedPlace.attr("data-row")] += "," + selectedPlace.attr("data-seat");
});
selectedPlaceTextFormated.shift();
for (var i = 0; i < selectedPlaceTextFormated.length; i++) {
var arr2 = selectedPlaceTextFormated[i].split(",");
arr2.shift();
textFormatted += "Row " + (i + 1) + " seats: (" + arr2.join(",") + ")\n";
}
alert(textFormatted);
​
Demo

I'd just do this:
var text = [];
$(".selected").each(function () {
var a = parseInt($(this).data('row'), 10),
b = $(this).data('seat');
text[a] = ((text[a])?text[a]+', ':'')+b;
});
var selectedPlaceTextFormated ='';
$.each(text, function(index, elem) {
if (!this.Window) selectedPlaceTextFormated += "Row " + index + " (seat " + elem + ")\n";
});
alert(selectedPlaceTextFormated);
