Hello Everyone.
Good day! I would like to seek some assistance on how to retain the newly created value in selectize. My code below worked fine. But one thing i noticed, everytime I moved to another control the value disappear. I want to know if i miss something in my code. Hope you can provide some guidance. Thank you.
$pmeds = $('#MainContent_admitmedicines').selectize({
loadingClass: 'selectizeLoading',
valueField: 'medID',
labelField: 'medicineName',
searchField: 'medicineName',
options: [],
delimiter: ',',
persist: false,
maxItems: 10,
create: function (input, callback) {
if (!input.length) return callback();
var id=0;
$.ajax({
url: 'DataService.asmx/addMedicines',
type: 'get',
dataType: 'json',
data: {
'profileID': docID,
'med': input
},
error: function () {
callback();
},
success: function (res) {
if (res) {
return callback({
value: res[0].medID,
text: res[0].medicineName
});
}
}
});
},
load: function (query, callback) {
if (!query.length) return callback();
$.ajax({
url: 'DataService.asmx/getMedicines',
method: 'post',
dataType: 'json',
data: {
profileID: docID
},
error: function () {
callback();
},
success: function (res) {
callback(res);
}
});
},
onChange: function (value) {
medsID.value = value;
}
});
