I need to get the value of elt.innerHTML and pass it to fromPage[j].textContent.
Function borrowed from GitHub.
Currently vars['hiddenNumber'] is returning undefined.
elt.style.visibility = "hidden"; works as intended tho.
I believe this might be related with variable scopes, but can't seem to find a way to create a global variable. Tried to update window.value, but got an error that window is not defined.
Using odoo 13, wkhtmltopdf 0.12.5.
<script>
function subst() {
var vars = {};
var x = document.location.search.substring(1).split('&');
for (var i in x) {
var z = x[i].split('=', 2);
vars[z[0]] = unescape(z[1]);
}
var index = vars['webpage'].split('.', 4)[3]
var operations = {
// other operations
'hidden_page_number': function (elt) {
elt.style.visibility = "hidden";
vars['hiddenNumber'] = elt.innerHTML; // This value
},
};
for (var klass in operations) {
var y = document.getElementsByClassName(klass);
for (var j=0; j<y.length; ++j)
operations[klass](y[j]);
}
var fromPage = document.getElementsByClassName('page');
for(var j = 0; j<fromPage.length; j++)
fromPage[j].textContent = vars['hiddenNumber']; // Required here
var toPage = document.getElementsByClassName('topage');
for(var j = 0; j<toPage.length; j++)
toPage[j].textContent = vars.sitepages;
}
</script>just a suggestion: you define vars outside the closure and then define closure where try to update vars but I suppose that inside the closure it creates new scope for vars and that's why vars is not updated outside
