I have this:
<table>
<tr>
<th>Name:</th>
<td>Carlos</td>
</tr>
<tr>
<th>Age:</th>
<td>22</td>
</tr>
</table>
And I need a JSON format.
{"Name":"Carlos","Age": 22}
I've tried with https://github.com/lightswitch05/table-to-json but it doesn't work for the headings in every row :(
EDIT: http://jsfiddle.net/Crw2C/773/
You can convert the table in the OP to the required format by first converting it to an Object, then using JSON.stringify to get the required string:
<table id="t0">
<tr>
<th>Name:</th>
<td>Carlos</td>
</tr>
<tr>
<th>Age:</th>
<td>22</td>
</tr>
</table>
<script>
function tableToJSON(table) {
var obj = {};
var row, rows = table.rows;
for (var i=0, iLen=rows.length; i<iLen; i++) {
row = rows[i];
obj[row.cells[0].textContent] = row.cells[1].textContent
}
return JSON.stringify(obj);
}
console.log(tableToJSON(document.getElementById('t0'))); // {"Name:":"Carlos","Age:":"22"}"
</script>
However, that is an ad hoc solution, so will need some work to be adapted to a more general case. It shows the concept though.
Note that there is no guarantee that the object properties will be returned in the same order as they appear in the table, you may get {"Age:":"22","Name:":"Carlos"}.
Assuming all you need is to get the first/second cells of each row as key/value pairs, you can use .reduce() to iterate of the rows and just grab the text content of .cells[0] and .cells[1] to use as each key/value pair:
var t = document.querySelector("table");
var j = [].reduce.call(t.rows, function(res, row) {
res[row.cells[0].textContent.slice(0,-1)] = row.cells[1].textContent;
return res
}, {});
document.querySelector("pre").textContent = JSON.stringify(j, null, 2);
<table>
<tr>
<th>Name:</th>
<td>Carlos</td>
</tr>
<tr>
<th>Age:</th>
<td>22</td>
</tr>
</table>
<pre></pre>
The Array.prototype.reduce method takes a collection and uses an accumulator to reduce it down to whatever state you want. Here we just reduce it to an object, so we pass one in after the callback.
For every row, we use the first cell's content as the object key, and the second cell's content as the value. We then return the object from the callback so that it's given back to us in the next iteration.
Finally, .reduce() returns the last thing we returned (which of course is the object we started with), and that's your result.
var t = document.querySelector("table");
var j = [].reduce.call(t.rows, function(res, row) {
res[row.cells[0].textContent.slice(0,-1)] = row.cells[1].textContent;
return res
}, {});
document.querySelector("pre").textContent = JSON.stringify(j);
<table>
<tr>
<th>Name:</th>
<td>Carlos</td>
</tr>
<tr>
<th>Age:</th>
<td>22</td>
</tr>
</table>
<pre></pre>
The Table-to-JSON library that you are using is expecting a different format in your table.
It is expecting a table with all of your headers in the first row, followed by the data in subsequent rows.
In other words, it's expecting your table to be structured like this
<table>
<tr>
<th>Name</th>
<th>Age</th>
</tr>
<tr>
<td>Carlos</td>
<td>22</td>
</tr>
</table>
Here's a forked version of your JSFiddle in which this is working.

I used cheerio for the first time today
This is a simplified version of the html source I want.
<div id="country-table">
<!-- div duplicate cause style -->
<div>
<div>
<table>
<tbody>
<tr>
<td>1</td>
<td>USA</td>
<td>1.6</td>
<td>75.8</td>
<td>132,000</td>
</tr>
<tr>
<td>2</td>
<td>INDIA</td>
<td>12123</td>
<td>1322</td>
<td>123213</td>
</tr>
<tr>
<td>3</td>
<td>BRAZIL</td>
<td>3123</td>
<td>213123</td>
<td>134</td>
</tr>
<tr>
<!-- and more... -->
</tbody>
</table>
</div>
</div>
</div>
and i tried to this:
const axios = require("axios").default;
const cheerio = require("cheerio").default;
axios.get("https://coronaboard.kr").then((html) => {
const arr = [];
const $ = cheerio.load(html.data, { xml: true, xmlMode: true });
const data = $("#country-table>div>div>table>tbody").each((index, item) => {
arr.push(item);
});
console.log(arr);
});
I want to put information in td into tr.
ex){number:x,name:USA,confirmed:x,and more...}
If anyone knows how to do it, please answer me!
If you're wanting to extract the data from the table, then this will help. Follow the comments to help you understand how it works.
var $ = cheerio.load(html.data);
// targets the specific table with a selector
var html_table = $('#country-table>div>div>table');
// gets table cell values; loops through all tr rows
var table_data = html_table.find('tr').map(function() {
// gets the cells value for the row; loops through each cell and returns an array of values
var cells = $(this).find('td').map(function() {return $(this).text().trim();}).toArray();
// returns an array of the cell data collected
return [cells];
}).toArray();
// output table data
console.log('table_data', table_data);
Hey im working on a project and i can't seem to get the hang of this. I want to loop through my nested array object "products" so that i can display it all and not just the last index.
// jquery getting our json order data from firebase
$.get("http://localhost:8888/orderslist", (data) => {
// i is for the index of the array of orders
let i = 0;
//for each loop through our array list
$.each(data, function () {
//console.log(data)
//console.log(i);
// is how we arrange the data and show it to the frontpage
$(`<table id = order_table_layout>
<tr>
<th>Customer</th>
<th>Date</th>
<th>Time</th>
<th>Total</th>
<th>Order</th>
<th>Order Status</th>
</tr>
<tr>
<td>${data[i].customer_name}</td>
<td>${data[i].date}</td>
<td>${data[i].time}</td>
<td>${data[i].total} Kr.</td>
<td>
${data[i].products[i].name}
${data[i].products[i].price} Kr.
</td>
<td>
</td>
</tr>
</table>`
).appendTo("#frontpage_new_ordertable");
// counts 1 up for each loop to go through list
i++;
//console.log(i);
});
});
Edit:
An example of the json data I'm working with look like this:
[
{
id: "4WQITi6aXvQJsKilBMns",
customer_name: "Susanne",
date: "22-12-2002",
time: "12:43:19",
total: 222,
products: [
{ name: "product name", price: 100 },
{ name: "product name2", price: 20 }
]
There's a couple of issues in your code. Firstly you're creating a brand new table for every object in the data array. It makes far more sense to instead create a new row in the table for each item.
Also, it appears that you want to loop through the child products array. As such you need an inner loop to create the HTML string for those elements outside of the template literal.
However it's worth noting that it's not good practice to have that much HTML in your JS. A better approach is to have a hidden template tr in your HTML which you can clone, update with the data from the data array, then append to the DOM in the tbody of the table.
With that said, try this:
//$.get("http://localhost:8888/orderslist", (data) => {
// mock response:
let data = [{id:"4WQITi6aXvQJsKilBMns",customer_name:"Susanne",date:"22-12-2002",time:"12:43:19",total:222,products:[{name:"product name",price:100},{name:"product name2",price:20}]},{id:"asjdkjk21ijjjew",customer_name:"Foo Bar",date:"10-05-2020",time:"16:46:16",total:68,products:[{name:"Lorem ipsum",price:50},{name:"Fizz buzz",price:18}]}];
let rows = data.map(item => {
let $clone = $('#frontpage_new_ordertable tfoot tr').clone();
$clone.find('.customer-name').text(item.customer_name);
$clone.find('.date').text(item.date);
$clone.find('.time').text(item.time);
$clone.find('.total').text(item.total + ' Kr.');
let products = item.products.map(prod => `${prod.name}: ${prod.price} Kr.`);
$clone.find('.products').html(products.join('<br />'));
return $clone;
});
$("#frontpage_new_ordertable tbody").append(rows);
//});
tfoot {
display: none;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<table id="frontpage_new_ordertable">
<tbody>
<tr>
<th>Customer</th>
<th>Date</th>
<th>Time</th>
<th>Total</th>
<th>Order</th>
<th>Order Status</th>
</tr>
</tbody>
<tfoot>
<tr>
<td class="customer-name"></td>
<td class="date"></td>
<td class="time"></td>
<td class="total"></td>
<td class="products"></td>
<td></td>
</tr>
</tfoot>
</table>
<td>${data[i].total} Kr.</td>
<td>
${data[i].products[i].name}
${data[i].products[i].price} Kr.
maybe that's what's wrong?
is the number of the order similar to the number of product in products array?
I have a list of HTML tables given by pandas data frame in the format of:

I am trying to visualize this data in an html page and could not do it. I do not have enough experience in web development. My goal is to use JavaScript to loop through each item the list and visualize them below each other in html. It would be great if anybody can help!
This is what I tried so far, its probably completely wrong:
var list_html = list_html // list of html codes as a javascript variable.
var arrayLength = analysis.length;
for (var i in list_html) {
document.getElementById("analysis_1").innerHTML = list_html[i];
}
Given a valid array of strings list_html (actually list_html is not a valid array of strings, since the markup in each entry is not wrapped in quotes) and a container in the DOM with id "analysis_1" it's simply a matter of:
var container = document.getElementById('analysis_1');
for (var i = 0; i < list_html.length; i++) {
container.innerHTML += list_html[i];
}
UPDATE:
well... in your scenario there is no need at all for a loop, you can simply inject a single string by joining the elements in the array:
document.getElementById('analysis_1').innerHTML = list_html.join('');
fast and simple! :)
using jquery's selectors :
Give the 'td' which contains the data a class name, eg: 'MyTd';
Select them all: $(.MyTd).text()
Done!
i had a table that submitted from my jquery append script, are its possible to find the match value with jquery selectors,
i want to check if the condition >= var $minimumEducation, it will pass to next page when submit, i set the value 0 for High School, 1 for Diploma and so on as it use selectbox, the var $minimumEducation variable come from my php admin, anyone knows how to pass this condition ? thanks
<thead>
<tr>
<th>Name</th>
<th>Relation</th>
<th>DOB</td>
<th>Education</th>
<th>Job</th>
</tr>
</thead>
<tbody>
<tr>
<td>John</td>
<td>Uncle</td>
<td>02/19/1955</td>
<td>Bachelor</td>
<td>Carpenter</td>
</tr>
<tr>
<td>Amy</td>
<td>Aunty</td>
<td>02/19/1950</td>
<td>Master</td>
<td>Housewife</td></tr>
<tr>
<td>Eddie</td>
<td>Cousin</td>
<td>02/19/1990</td>
<td>Diploma</td>
<td>Editor</td>
</tr>
</tbody>
</table>
You can select each matched element using the :has selector. To match against minimum education you must build the selector string based on the array mapping the education strings to the $minimumEducation value
$( "tr:has(td[value="bachelor"], td[value="master"])" )
This can be generated similar to the following
var query = "";
for (var i = minimumEducation; i < eduarray.length; i++) {
query += ', td[value="'+eduarray[i]+'"]';
}
query = query.substring(1);
Then just put the query string inside the selector
$( "tr:has("+query+")" )
I have a table and I need to get values for each row (in array), something like:
[{1,'test'}, {2,'another test'}, {3, 'nothing'}], but the only I can get is:
["1 test", "2 another test","3 nothing"]. I need to send this values by ajax as json object ... and create another table - thus I need an array of values ...
var table = $("table");
var rowsAll = table.find("tbody tr");
rowsAll.each(function(i,l) {
var rows = [];
$(this).each(function(t,l){
rows[rows.length] = cells[t]= $(this).text();
return rows; //returns rows, but I need cells of each row
}).serialize();//or get()
});
the html is something like this:
<table id="deal">
<thead>
<tr>
<th> num </th>
<th> string </th>
</tr>
</thead>
<tbody>
<tr> <td> 1 </td> <td> test </td> </tr>
<tr> <td> 2 </td> <td> another test </td> </tr>
<tr> <td> 3 </td> <td> nothing </td> </tr>
</tbody>
</table>
I really need help ...
This form of data makes no sense as it's very hard to read with javascript:
[{1,'test'}, {2,'another test'}, {3, 'nothing'}]
I'm going to assume that what you want is this:
{"1": "test", "2": "another test", "3": "nothing"}
To get that second form, you could use this code:
var results = {};
$("#deal tbody tr").each(function() {
var cols = $(this).find("td");
results[$.trim(cols.eq(0).text())] = $.trim(cols.eq(1).text());
});
