VisualizaçõesGet values from HTML only if the checked box is checked (HTML + Python script)
I have a web page with multiple checkboxes and the relative input values
with the following code:
<tr><td><input type=\"checkbox\" id=\"second_checkbox\" name=\"second_checkbox\" value=\"" + Sample_ID + "\"><label for=\""+ Sample_ID + "\">"+ Sample_ID +"</label><br></td><td><select name=\"option\" id=\"option\"><option value=\"\" selected=\"selected\"></option><option value=\"=\">=</option><option value=\"!=\">!=</option><option value=\">\">></option><option value=\">=\">>=</option><option value=\"<\"><</option><option value=\"<=\"><=</option><option value=\"ilike\">contains</option></select></td><td><input type=\"text\" name=\"valore\" placeholder=\"value\"></td></tr>"and I get the different values by using this functions:
filtri = request.form.getlist('second_checkbox')
simbolo = request.form.getlist('option')
valori = request.form.getlist('valore')
but the array "valori" takes all the empty values on the page and I want to take only the ones that are checked on the first checkbox. How can I do that?
Thanks

First, remove the duplicate id's and names in the html. An id in html should be unique. Using the right selection mechanism you don't need them either.
For the client side (so, within the browser) you can select all checked checkboxes using the selector [type=checkbox]:checked. Here's a minimal reproducable example.
document.addEventListener(`click`, evt => {
console.clear();
const allChecked = document.querySelectorAll(`[type='checkbox']:checked`);
// ^ only checked
if (allChecked.length) {
return allChecked
.forEach(cb => {
const theRow = cb.closest(`tr`);
console.log(`checked row (#${theRow.rowIndex + 1}) text input value: ${
theRow.querySelector(`input[type='text']`).value || `no value`}`);
});
}
return console.log(`none checked (yet)`);
});<table>
<tr>
<td>
<input type="checkbox" value="123"> 123
</td>
<td>
selector here
</td>
<td>
<input type="text" placeholder="value" value="row 1">
</td>
</tr>
<tr>
<td>
<input type="checkbox" value="456"> 456
</td>
<td>
selector here
</td>
<td>
<input type="text" placeholder="value" value="row 2">
</td>
</tr>
<tr>
<td><input type="checkbox" value="789"> 789
<td>
selector here
</td>
<td>
<input type="text" placeholder="value" value="row 3">
</td>
</tr>
</table>
