HTML table data to JSON
/*
* THIS IS NOT A PLUGIN
* ~ but a personal snippet
*
* Sometimes when prototyping my designs, I like to get dummy data pretty fast.
* I use this snippet to extract that data from working (aka "real life") tables from other HTML tables I find on the net.
* So I'll need that same data but inside an object.
*
* This script assumes by default the table has the following structure:
* <table>
* <thead>
* <tr><th>
* <tbody>
* <tr><td>
*/
var o = { // default options
selectors: {
table: 'table',
th: 'thead th', // relative to $table
tr: 'tbody tr' // relative to $table
}
},
$table,
data = [],
headings = [],
log = console.log;
$table = document.querySelector(o.selectors.table);
// Get headings
$table.querySelectorAll(o.selectors.th).forEach((th) => {
headings[headings.length] = th.innerText;
});
$table.querySelectorAll(o.selectors.tr).forEach((tr, row) => {
var obj = data[row] = {};
tr.querySelectorAll('td').forEach((td, i) => {
obj[headings[i]] = td.innerText;
})
});
log(JSON.stringify(data));
