Using the js library called pdform.js, the pdf form was read as follows:
Other text forms and individual check boxes encode normally.
Only check boxes, radio buttons, and select boxes cannot be encoded. No matter how hard I look, I can't answer.
The code is too long to attach, but I think there is a problem with the code below here.
function list(buf) {
var list_form = document.querySelector('.list_form');
empty(list_form);
var cnt = 1;
var field_specs;
try {
field_specs = make_pdfform().list_fields(buf);
} catch (e) {
on_error(e);
return;
}
for (var field_key in field_specs) {
var row = document.createElement('div');
row.appendChild(document.createTextNode(field_key));
list_form.appendChild(row);
field_specs[field_key].forEach(function(spec, i) {
for(var key in spec) console.log(key + " = " + spec[key]);
if ((spec.type === 'radio') && spec.options) {
var fieldset_el = document.createElement('fieldset');
spec.options.forEach(function(ostr) {
var label = document.createElement('label');
var radio = document.createElement('input');
radio.setAttribute('type', 'radio');
radio.setAttribute('value', ostr);
radio.setAttribute('name', field_key + '_' + i);
radio.setAttribute('data-idx', i);
radio.setAttribute('data-key', field_key);
label.appendChild(radio);
label.appendChild(document.createTextNode(ostr));
fieldset_el.appendChild(label);
});
row.appendChild(fieldset_el);
return;
}
var input = document.createElement((spec.type === 'select') ? 'select' : 'input');
input.setAttribute('data-idx', i);
input.setAttribute('data-key', field_key);
if (spec.type === 'boolean') {
input.setAttribute('type', 'checkbox');
} else if (spec.type === 'string') {
} else if ((spec.type === 'select') && spec.options) {
spec.options.forEach(function(ostr) {
var option_el = document.createElement('option');
//problem part
option_el.appendChild(document.createTextNode(ostr));
option_el.setAttribute('value', ostr);
input.appendChild(option_el);
});
}
row.appendChild(input);
});
}
}
