How can I check in jQuery if inputs with name denominationcomune_{{loop.index}} and denominationcomune_{{loop.index}} are empty not all inputs ?
I have a twig like this:
<form action="" method="post">
{% for mat in mat_temp_array %}
<input type="text" name="nomentite_{{loop.index}}"/>
<input type="text" name="denominationcomune_{{loop.index}}" value="{{ mat.denominationcommun }}"/>
<input type="text" name="denominationcomerce_{{loop.index}}" value="{{ mat.denominationcomerce }}"/>
{% endfor %}
<input type="submit" class="btn" value="save"/>
</form>
This question is related to
javascript
jquery
symfony
twig
var empty = true;
$('input[type="text"]').each(function() {
if ($(this).val() != "") {
empty = false;
return false;
}
});
This should look all the input and set the empty var to false, if at least one is not empty.
EDIT:
To match the OP edit request, this can be used to filter input based on name substring.
$('input[name*="denominationcomune_"]').each(...
Define a helper function like this
function checkWhitespace(inputString){
let stringArray = inputString.split(' ');
let output = true;
for (let el of stringArray){
if (el!=''){
output=false;
}
}
return output;
}
Then check your input field value by passing through as an argument. If function returns true, that means value is only white space.
As an example
let inputValue = $('#firstName').val();
if(checkWhitespace(inputValue)) {
// Show Warnings or return warnings
}else {
// // Block of code-probably store input value into database
}
You can do it using simple jQuery loop.

You could do it like this :
bool areFieldEmpty = YES;
//Label to leave the loops
outer_loop;
//For each input (except of submit) in your form
$('form input[type!=submit]').each(function(){
//If the field's empty
if($(this).val() != '')
{
//Mark it
areFieldEmpty = NO;
//Then leave all the loops
break outer_loop;
}
});
//Then test your bool
$('input[type="text"]').get().some(item => item.value !== '');
I'd suggest to add an class='denominationcomune' to all elements that you want to check and then use the following:
function are_elements_emtpy(class_name)
{
return ($('.' + class_name).filter(function() { return $(this).val() == ''; }).length == 0)
}
