angular.js how to parse variable data inside view - javascript

I have this variable:
var number = "1,10,25,60";
How can I parse it inside a view into this form?
<tr>
<td ng-click="ctrl.set(1)>1</td>
<td ng-click="ctrl.set(10)>10</td>
<td ng-click="ctrl.set(25)>25</td>
<td ng-click="ctrl.set(60)>60</td>
</tr>
In normal js I would just do var numbers = number.split(","); and then some loop like so:
var html;
for (i = 0; i <= numbers.length; i++) {
html += "<td ng-click='ctrl.set" + numbers[i] + "'>" + numbers[i] + "</td>";
}
Maybe some directive?

Assign it to a $scope var (the split result)
var number = "1,10,25,60";
$scope.numbers = number.split(",");
And the view:
<tr ng-repeat="num in numbers">
<td ng-click="ctrl.set(num)>{{num}}</td>
</tr>

ng-repeat will iterate through an array:
<html>
<head>
<script data-require="angular.js#1.3.x" src="https://code.angularjs.org/1.3.17/angular.js"></script>
</head>
<body ng-app >
<input ng-model="$scope.numbers" ng-init="$scope.numbers = [1,10,25,60]"/>
<table>
<tbody>
<tr>
<td ng-repeat="n in $scope.numbers track by $index"
ng-click="console.log(n);$scope.selected = n">{{n}}
</td>
</tr>
</tbody>
</table>
<div>{{$scope.selected}}</div>
</body>
</html>

Change <p> to <table>

I wants to change the output of the <p id="demo> to <table> with <tr> and <td>but it involved Javascript in the output so it doesn't on what I've tried.
<button onclick="myFunction()">Predict</button>
<div id="demo" align="center"></div>
<script type="text/javascript">
var selectedprg = '';
var selectedcount = '';
var selectedcity = '';
var average = '';
function myFunction() {
document.getElementById("demo").innerHTML = `
<table>
<tr>
<td style="padding: 5px;">Selected program</td>
<td style="padding: 5px;">${selectedprg}</td>
</tr>
<tr>
<td style="padding: 5px;">Total number of students</td>
<td style="padding: 5px;">${selectedcount}</td>
</tr>
</table>'
}
$(document).ready(function(){
$("#prg").change( function(){
selectedprg = $('#prg option:selected').text();
selectedcount = $('#prg option:selected').data('prgcount');
selectedcity = $('#prg option:selected').data('citycount');
if(selectedcount > 5){
average = selectedcount / 3 + 5;
} else{
average = selectedcount / 3 - 5;
}
});
});
</script>
Current output
Expected output
Could someone assist on this? Thank you.
You can do something like this:
document.getElementById("demo").innerHTML = `
<table>
<tr>
<td style="padding: 5px;">Selected program</td>
<td style="padding: 5px;">${selectedprg}</td>
</tr>
<tr>
<td style="padding: 5px;">Total number of students</td>
<td style="padding: 5px;">${selectedcount}</td>
</tr>
</table>
`
the styling should be writing with css ofcourse.

HTML table with editable fields accessed in javascript.

I am trying to build a table that will allow users to change the value of a cell(s) and then "submit" that data
to a JavaScript (only please) method that turns the tables data into a json dataset.
I started by trying to updated the value of just one field. QTY in this case. I am able to loop over the table and get the static values, but I am not able to catch the user input value.
question: What is a JavaScript only (if possible) way to capture user change(able) values from a table?
function updateQTY() {
//getData from table
//gets table
var lines = "";
var oTable = document.getElementById('items');
//gets rows of table
var rowLength = oTable.rows.length;
var line = "";
//loops through rows, skips firts row/header
for (i = 1; i < rowLength; i++) {
//gets cells of current row
var oCells = oTable.rows.item(i).cells;
var qty = oCells.item(2).innerHTML;
//alert("qty: " + wty);
qty = qty.substr(oCells.item(2).innerHTML.indexOf('value=') + 7);
qty = qty.substr(0, qty.indexOf('" class='));
//alert(qty);
line = line +
'{ "item": "' + oCells.item(0).innerHTML + '",' +
' "discription": "' + oCells.item(1).innerHTML + '",' +
' "qty": "' + qty + '"},'
}
//alert(line);
var jsonData = JSON.parse('[' + line + '{"quickwayto":"dealwith,leftbyloop"}]');
alert("lines: " + JSON.stringify(jsonData));
}
<form action='#'>
<table class='mdl-data-table mdl-js-data-table' id='items'>
<thead>
<tr>
<th>item</th>
<th>discription</th>
<th>QTY</th>
</tr>
</thead>
<tbody>
<tr>
<td class='mdl-data-table__cell--non-numeric'> widget_1 </td>
<td class='mdl-data-table__cell--non-numeric'>it's fun</td>
<td>
<div class='mdl-textfield mdl-js-textfield'><input type='text' name='qty1' id='value1' value='5' class='mdl-textfield__input'></div>

</tr>
</tbody>
</table>

<input type='button' value='update' onclick='updateQTY()' class='mdl-button mdl-js-button mdl-button--raised mdl-js-ripple-effect'>

</form>
THANK YOU
Instead of selecting the entire td element, retrieve only what you really need using querySelector (or use jQuery if possible). Find the input element and access the value, it's a lot easier than doing all of that unecessary parsing of the inner html of the entire cell.
function updateQTY() {
//getData from table
//gets table
var lines = "";
var oTable = document.getElementById('items');
//gets rows of table
var rowLength = oTable.rows.length;
var line = "";
//loops through rows, skips firts row/header
for (i = 1; i < rowLength; i++) {
//gets cells of current row
var oCells = oTable.rows.item(i).cells;
var qty = oCells.item(2).querySelector(".mdl-textfield__input").value;
line = line +
'{ "item": "' + oCells.item(0).innerHTML + '",' +
' "discription": "' + oCells.item(1).innerHTML + '",' +
' "qty": "' + qty + '"},'
}
//alert(line);
var jsonData = JSON.parse('[' + line + '{"quickwayto":"dealwith,leftbyloop"}]');
alert("lines: " + JSON.stringify(jsonData));
}
<form action='#'>
<table class='mdl-data-table mdl-js-data-table' id='items'>

You need to use document.getElementById('value2').value instead of .innerHTML.indexOf('value=')
You're making yourself a lot of work here. You have a table. All you need to do is convert that to JSON. I would suggest you look at the library below that does that in around one line of native java-script.

How to get checked checkbox table value in jquery

In my table I have 2 rows please see my screen shot,suppose I click first check box means I want to take that id ** and **to_area value in jquery how can do this,I tried but I can not get please help some one
$(document).ready(function() {
$('#chemist_allotment_btn').click(function() {
if ($('#chemist_allotment_form').valid()) {
$.ajax({
url: 'update_chemist_bulk_transfer.php',
type: 'POST',
data: $('form#chemist_allotment_form').serialize(),
success: function(data) {
var res = jQuery.parseJSON(data); // convert the json
console.log(res);
if (res['status'] == 1) {
var htmlString = '';
$.each(res['data'], function(key, value) {
htmlString += '<tr>';
htmlString += ' <td class="sorting_1"><div class="checkbox-custom checkbox-success"><input type="checkbox" id="checkboxExample3" name="getchemist" class="getchemist" value="' + value.id + '"><label for="checkboxExample3"></label></div></td>';
htmlString += '<td>' + value.id + '</td>';
htmlString += '<td>' + value.name + '</td>';
htmlString += '<td>' + value.area + '</td>';
htmlString += '<td>' + value.to_area + '</td>';
htmlString += '<td>' + value.address + '</td>';
htmlString += '</tr>';
});
$('#SampleDT tbody').empty().append(htmlString);
$('#get_to_area').click(function() {
var id = $('input[name=getchemist]:checked').val();
if ($(".getchemist").prop('checked') == true) {
alert(id);
alert(value.to_area);
} else {
alert('Please Check');
}
});
} else {
$('#SampleDT tbody').empty().append('No Datas Found');
}
},
});
return false;
}
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="well white">
<table id="SampleDT" class="datatable table table-hover table-striped table-bordered tc-table">
<thead>
<tr>
<th>Select</th>
<th>Id</th>
<th>Doctor Name</th>
<th>From Area</th>
<th>To Area</th>
<th>Address</th>
</tr>
</thead>
<tbody>
</tbody>
</table>
<center>
<div class="form-group">
<button type="button" class="btn btn-primary" style="text-align:left;" id="get_to_area">Transfer Area</button>
</div>
</center>
</div>
Firstly, add classes to each <td>, like <td class='id'>[Your id]</td>
Similarly for all the elements doctor-name, to-area, etc and a class to each <tr> like row-select
Somewhat like this:
<tr class="row-select">
<td class="select">...</td>
<td class="id">...</td>
<td class="to-area">...</td>
.
.
.
</tr>
Use jQuery like this:
$('.row-select').click(function(){
var id,toArea,checkBox;
id = $(this).find('.id').html(); //get the ID field
toArea = $(this).find('.to-area').html(); //get the to-area field
checkBox = $(this).find('.select > input');
checkbox.prop('checked',!checkbox.prop('checked'));
})
This code will get you he value no mater where you click on the row, and also invert the selection on the checkbox
To get the values of rows selected when the form is submitted run a loop like this
$('.row-select input:checked').each(function(){
var id,toArea,checkBox;
id = $(this).closest('tr').find('.id').html(); //get the ID field
toArea = $(this).closest('tr').find('.to-area').html(); //get the to-area field
})
EDIT
All together:
$(document).ready(function() {
$('#btnSubmit').click(function() {
$('.row-select input:checked').each(function() {
var id, name;
id = $(this).closest('tr').find('.id').html();
name = $(this).closest('tr').find('.name').html();
alert('ID: ' + id + " | Name: " + name);
})
})
$('#btnSelectAll').click(function() {
$('.row-select input').each(function() {
$(this).prop('checked', true);
})
})
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<table border=1>
<tr class="row-select">
<td class="check">
<input type="checkbox" />
</td>
<td class="id">12</td>
<td class="name">Jones</td>
</tr>
<tr class="row-select">
<td class="check">
<input type="checkbox" />
</td>
<td class="id">10</td>
<td class="name">Joseph</td>
</tr>
</table>
<button id="btnSelectAll">Select all</button>
<button id="btnSubmit">Get Value</button>
Process step-by-step:
Give the td you need some classes (from-a & to-a);
Initialize an empty array all (we'll store the data inside it later on);
Create a function that is triggered by the checkbox change
Inside the function you need to know which checkbox has changed, what's the state of it, what tr does it belong to and at the end what are the TO AREA and FROM AREA values.
If the state = checked we will add the values to the all (our small data storage);
If the state = not-checked we will remove the value from the all array;
Finally when we are done with selecting and deselecting rows by pressing the button we can get the values of the selected rows.
var all = [];
$('input[type="checkbox"]').change(function(){
var checkbox = $(this);
var state = checkbox.prop('checked');
var tr = checkbox.parents('tr');
var from = tr.children('.from-a').text();
var to = tr.children('.to-a').text();
if(state){
all.push(from + ' -> ' + to);
}else{
var index = all.indexOf(from + ' -> ' + to);
all.splice(index, 1);
}
})
$('#get_to_area').click(function(){
alert(all);
});

This is just the basic concept, you can modify it to suit your needs, I'll be happy to help you if you get stuck.
You can also use this fiddle:
In JS:
$('#get_to_area').click(function () {
var id = $('input[name=getchemist]:checked').val();
if ($('input[name=getchemist]').is(':checked')) {
var ID = $('input[name=getchemist]').parent().parent().siblings('td.chkid').html();
var TO_Area = $('input[name=getchemist]').parent().parent().siblings('td.toarea').html();
}
else {
alert('Please Check');
}
});
In Html:
if (res['status'] == 1) {
var htmlString = '';
$.each(res['data'], function (key, value) {
htmlString += '<tr>';
htmlString += ' <td class="sorting_1"><div class="checkbox-custom checkbox-success"><input type="checkbox" id="checkboxExample3" name="getchemist" class="getchemist" value="' + value.id + '"><label for="checkboxExample3"></label></div></td>';
htmlString += '<td class="chkid">' + value.id + '</td>';
htmlString += '<td>' + value.name + '</td>';
htmlString += '<td>' + value.area + '</td>';
htmlString += '<td class="toarea">' + value.to_area + '</td>';
htmlString += '<td>' + value.address + '</td>';
htmlString += '</tr>';
});
I'm guessing you need values of each td whose checbox are checked. This piece of code should get you started.
As you can see, Code loops through each checkbox which is checked, gets contents inside its corresponding td.
var Result = new Array();
$('.checkbox-custom input[type="checkbox"]:checked').each(function(){
var _this = $(this).closest('tr').find('td');
var id= $(_this).eq(0);
var name = $(_this).eq(1);
................... //Similar way for the others
Result.Push(id,name,....)
});

For loop with array doesn't work with innerHTML

I have a div with the ID="ranking" and I'd like to put there some info of a JavaScript array with a table where every row has tow columns: one for dados[i][25] and other for dados[i][26].
My code is this:
function dadosRanking(dados){
document.getElementById("ranking").innerHTML += '<table class="table"><tr><td valign="middle" class="question" colspan=2><h1>RANKING (+ PONTOS)</h1></td></tr><tr><td>PONTOS</td><td>UTILIZADOR</td></tr>'
for(var i=1;i<6;i++)
{
document.getElementById("ranking").innerHTML += '<tr><td>' + dados[i][25] + '</td><td>' + dados[i][26] + '</td></tr>';
}
document.getElementById("ranking").innerHTML += '</table>';
}
The code I expect was this:
<table class="table">
<tr>
<td valign="middle" class="question" colspan=2>
<h1>RANKING (+ PONTOS)</h1>
</td>
</tr>
<tr>
<td>PONTOS</td>
<td>UTILIZADOR</td>
</tr>
<tr>
<td>
100
</td>
<td>
Username
</td>
</tr>
</table>
However, the HTML code script write is this:
<table class="table">
<tr>
<td valign="middle" class="question" colspan=2>
<h1>RANKING (+ PONTOS)</h1>
</td>
</tr>
<tr>
<td>PONTOS</td>
<td>UTILIZADOR</td>
</tr>
</table>
"100Username"
Everytime you update innerHTML the browser will parse it and render it, to do that it will also try to 'fix' your HTML. This can have unintended consequences. Instead of pushing to innerHTML with a partial table definition, collect the HTML in a separate value and push to innerHTML once.
function dadosRanking(dados){
var s = "";
s += '<table class="table"><tr><td valign="middle" class="question" colspan=2><h1>RANKING (+ PONTOS)</h1></td></tr><tr><td>PONTOS</td><td>UTILIZADOR</td></tr>'
for(var i=1;i<6;i++) {
s += '<tr><td>' + dados[i][25] + '</td><td>' + dados[i][26] + '</td></tr>';
}
s += '</table>';
document.getElementById("ranking").innerHTML += s;
}
After
document.getElementById("ranking").innerHTML += '<table class="table"><tr><td valign="middle" class="question" colspan=2><h1>RANKING (+ PONTOS)</h1></td></tr><tr><td>PONTOS</td><td>UTILIZADOR</td></tr>'
innerHTML becomes:
<table class="table">
<tr><td valign="middle" class="question" colspan=2><h1>RANKING (+ PONTOS)</h1></td></tr>
<tr><td>PONTOS</td><td>UTILIZADOR</td></tr>
</table>
Note that the table has been closed!
After
document.getElementById("ranking").innerHTML += '<tr><td>foo</td><td>bar</td></tr>';
innerHTML becomes
<table>..</table>
foobar
<tr> and <td> are not valid outside of a table context so they're removed.
After
document.getElementById("ranking").innerHTML += '</table>';
innerHTML doesn't change because </table> doesn't do anything, there is no table to close.

JQuery For each loop with HTML table data

So I have an HTML table that looks like the following.
<div class="timecard">
<h3>tommytest</h3>
<table class="misc_items timecard_list" border="0" cellpadding="2" cellspacing="0" style="margin:0 auto;">
<tbody>
<tr class="display_row odd">
<td align="left" class="job_code" style="color:#000099">2400-Orchard</td>
<td align="right">9:47am</td>
<td align="right">5/19/2014</td>
<td align="right" class="hrs">01:00</td>
</tr>
<tr class="display_odd row">
<td align="left" class="job_code" style="color:#000099">1200-Duffy's</td>
<td align="right">12:37am</td>
<td align="right">5/17/2014</td>
<td align="right" class="hrs">2:00</td>
</tr>
</tbody>
</table>
</div>
<div class="timecard">
<h3>testtest</h3>
<table class="misc_items timecard_list" border="0" cellpadding="2" cellspacing="0" style="margin:0 auto;">
<tbody>
<tr class="display_row odd">
<td align="left" class="job_code" style="color:#000099">2400-Orchard</td>
<td align="right">9:47am</td>
<td align="right">5/19/2014</td>
<td align="right" class="hrs">01:00</td>
</tr>
<tr class="display_odd row">
<td align="left" class="job_code" style="color:#000099">1200-Duffy's</td>
<td align="right">12:37am</td>
<td align="right">5/17/2014</td>
<td align="right" class="hrs">2:00</td>
</tr>
</tbody>
</table>
</div>
<div id="total"></div>
Then I have a jquery script that takes the total "job_code" hours and adds them up for each individual one. However, right now the script combines "tommytest" and "testtest" job codes together. I'm trying to get it to calculate each one individually and print it underneath each's respected table. Any ideas are greatly appreciated.
$(document).ready(function () {
var timeString = $(this).next('td.hrs').text();
var components = timeString.split(':');
var seconds = components[1] ? parseInt(components[1], 10) : 0;
var hrs = parseInt(components[0], 10) + seconds / 60;
total += hrs;
var temp = [];
$('.job_code').each(function (index, element) {
var text = $(this).text();
if (text != 'Out') {
temp.push(text);
}
});
// remove duplicates
var job_code = [];
$.each(temp, function (index, element) {
if ($.inArray(element, job_code) === -1) job_code.push(element);
});
var sum = {};
$.each(job_code, function (index, element) {
var total = 0;
$('.job_code:contains(' + element + ')').each(function (key, value) {
var timeString = $(this).siblings('td.hrs').text();
var components = timeString.split(':');
var seconds = components[1] ? parseInt(components[1], 10) : 0;
var hrs = parseInt(components[0], 10) + seconds / 60;
total += hrs;
sum[index] = {
'job_code': element,
'total': total
};
});
});
console.log(sum);
$.each(sum, function (index, element) {
$('#total').append('<p>Total for ' + element.job_code + ': ' + element.total + '</p>');
});
});
Link to jsFiddle: http://jsfiddle.net/Ha546/2/
If at all possible I'd like this to be dynamic as there will be more than just these two tables. Thanks ahead of time for the help.
When you query for the TD tags, $(this).next('td.hrs') you are not being specific enough about which table you want the TD tags from. If you are more specific, for example, adding an id to the tables,
<table id="tommytest">...</table>
<table id="testtest">...</table>
then you can query by table like so:
var tdsFromTommytest = $(this).next('#tommytest td.hrs')
var tdsFromTesttest = $(this).next('#testtest td.hrs')
Now that you have the two separate TD lists, you can process how you want. That, I think is the crux of your problem. But hopefully that helps you enough to see how you'd update a separate total tag under each table.
You could do this for tommyTest and subsequently for testtest :
Add id to the individual table
<table id="tommyTest">
And in javascript create different method for calculating the value :
$('#tommyTest').find('.job_code').each(function (index, element) {
var text = $(this).text();
if (text != 'Out') {
temp.push(text);
}
});
