I have a function which gets values from elements:
function getTransactionValues() {
var o = {};
o.reservations = [];
$('#custom-headers option:selected').each(function (i, selected) {
o.reservations[i] = $(selected).val();
});
o.amount = $('input[name=amount-price]').val();
o.currency_value = $('input[name=currency-value]').val();
o.currency_name = $('.currency_appendto option:selected').html();
o.actual_amount = $('input[name=actual-amount]').val();
o.actual_remaining = $('input[name=actual-remaining]').val();
o.funds_arrival_date = $('input[name=funds-arrival]').val();
o.paid_to = $('.paidto option:selected').html();
o.checkbox = $('.multi-transaction:checked').map(function () {
return this.value
}).get();
return o;
}
Now i want to check whether amount, actual_amount and funds_arrival_date are filled. if they are i will release the disabled class from a button. i've tried
var check_review = function () {
var a = getTransactionValues();
var options = [a.amount, a.actual_amount, a.funds_arrival_date];
for(i = 0; i < options.length; i++) {
if(options[i].length > 0) {
$('a[name=review_button]').removeClass('disabled');
}
else{
//this array is empty
alert('There is a problem!');
}
}
}
$('.test').click(function() {
check_review();
});
But it doesn't seems to be working..
Remove disabled attribute using JQuery?
Can you please look at above link, I think we should use $('.inputDisabled').prop("disabled", false);
Even if a single array element will be non empty then your code will remove the class disabled
from the a
. To make sure that all the elements of array are non empty and then only you want to remove the class then the way is:
for(i = 0; i < options.length; i++) {
if(options[i].length > 0) {
$('a[name=review_button]').removeClass('disabled');
}
else{
$('a[name=review_button]').addClass('disabled');
}
}
Or the other way is
var check = true;
for(i = 0; i < options.length; i++) {
if(options[i].length == 0) {
check = false;
}
}
if(check ) $('a[name=review_button]').removeClass('disabled');
Try using Array.prototype.every()
if (options.every(Boolean)) {
$("a[name=review_button]").removeClass("disabled");
} else {
// do other stuff
}
