Javascript If statement not working in autocomplete

I have the following Javascript code that works perfectly as far as the autocompleting as well as filling 5 additional input fields, based on the loaded array from MySQL in the type_code.php file.
The sixth element of the array val(names[6]) is filled with a database value of either Yes or No and I am trying to use this value to control whether an additional form field becomes readonly or readwrite at the front end.
It seems as if my if statement is badly formatted, as if I run the two lines of codes without the if everything works as expected.
// Autocomplete Invoice To from Code and sets ReadOnly/ReadWrite based on Editable field in Code record
$('#add_at_inv2_code1').autocomplete({
source: function( request, response ) {
$.ajax({
url : 'type_code.php',
dataType: "json",
method: 'post',
data: {
name_startsWith: request.term,
type: 'code_table',
row_num : 1
},
success: function( data ) {
response( $.map( data, function( item ) {
var code = item.split("|");
return {
label: code[0],
value: code[0],
data : item
}
}));
}
});
},
autoFocus: true,
minLength: 0,
select: function( event, ui ) {
var names = ui.item.data.split("|");
$('#desc_at_inv2_code1').val(names[1]);
$('#add_at_inv2_code2').val(names[2]);
$('#add_at_inv2_client').val(names[3]);
$('#add_at_salesrep').val(names[4]);
$('#add_at_category').val(names[5]);
// Code that is not working
if($(val(names[6])) == "Yes") {
$('#add_at_inv2_client').prop('readonly',false);
$('#add_at_inv2_client').prop('disabled',false);
} else {
$('#add_at_inv2_client').prop('readonly',true);
$('#add_at_inv2_client').prop('disabled',true);
}
}
});
Can someone please help me structure this if statement correctly?
Thanks,
Adri

The val() method returns or sets the value attribute of the selected elements.
Note: The val() method is mostly used with HTML form elements.
Use
if(names[6] == "Yes")
instead of
if($(val(names[6])) == "Yes")

Need following change in your code

$('#add_at_inv2_client').prop('readonly',false);
$('#add_at_inv2_client').prop('disabled',false);

else

Jquery autocomplete only shows results after i type 4th letter on input

I have a input where a user inserts a city name, and then i call a method with onkeyup
function autocompleteCity(id){
console.log($('#'+id).val());
if($('#'+id).val().length >= 2){
var data = {
query: $('#'+id).val()
}
$.ajax({
url: location.origin + '/autocomplete/city',
headers: {
apiKey: APIKEY
},
type: "POST",
data: data,
dataType: "json",
async: true,
success: function (data) {
var cities = [];
for(var i=0;i<data.cities.length;i++){
cities.push(data.cities[i].city);
}
console.log(cities);
$('#'+id).autocomplete({
source: cities
});
},
error: function (err) {
console.log(err);
}
});
}
}
and html
<input id="placeTo" onkeyup="autocompleteCity('placeTo')" type="text" class="form-control input-lg not-dark" value="" placeholder="Select a drop city">
For example if i type "To" i get this on console.log(cities)
Array [ "Toulouse", "Toronto", "Torun", "Tours" ]
but the autocomplete doesn't show, until the user types "Toky"
is this normal? or am i doing something wrong?

For your ajax you just need to implement the source option and for the minimum number of characters a user must type there is the minLength option.
$( "#city" ).autocomplete({
source: function( request, response ) {
$.ajax( {
url: location.origin + '/autocomplete/city',
dataType: "json",
type: "POST",
headers: {
apiKey: APIKEY
},
data: {
q: request.term
},
success: function( data ) {
// Handle 'no match' indicated by [ "" ] response
response( data.length === 1 && data[ 0 ].length === 0 ? [] : data );
}
} );
},
minLength: 2,
select: function( event, ui ) {
log( "Selected: " + ui.item.label );
}
}):

Initialize a autocomplete with the minLength option specified.
$( ".selector" ).autocomplete({ minLength: 2 });
It will work

Display the name but submit the ID with jQuery tag-it

Thanks for your time reading and helping!
I'm using the jQuery "tag-it" plugin: https://github.com/aehlke/tag-it
I've already checked the current questions and answers on the site, but they didn't help to achieve the 100% of what I need. I need help with the last step.
What I'm trying to do is, when the user is writing an email address, the system suggests what users belong to that address.
The suggestions are generated in a PHP page and I take them using AJAX from the plugin. The format given is this:
[
{"value": "13", "label": "Mauricio"},
{"value": "4", "label": "Manolo"}
]
"value" is the ID of the user and "label", the name of the person.
In the example, "Manalo" and "Mauricio" are displayed as suggestions to select. But when they are selected, what is displayed is the ID of the user (the "value"), not the name (the "label").
What I want to do is to display the name of the selected users but when I send the form, only the IDs are sent.
This is the current code. Thanks a lot for the help again.
$(".users").tagit({
autocomplete: {
source: function(request, response) {
$.ajax({
type: "GET",
url: 'test_json.php?text=' + request.term,
dataType: "json",
success: function(data) {
response( $.map( data, function( item ) {
return {
label: item.label,
value: item.value
}
}));
}
});
},
},
});

Get the selected option value from the jquery Autocomplete
$(".users").tagit({
autocomplete: {
source: function(request, response) {
$.ajax({
type: "GET",
url: 'test_json.php?text=' + request.term,
dataType: "json",
success: function(data) {
response( $.map( data, function( item ) {
return {
label: item.label,
value: item.value
}
}));
},
select: function(event, ui) {
//For better understanding kindly alert the below commented code
var selectedObj = ui.item;
alert(selectedObj.value);
}
});
},
},
});

How to get the unique value in autocomplete in php from mysqldatabase

jQuery UI Autocomplete: How to base on JSON data NOT name & Label

I've got an AJAX url that returns data in the following format:
[{ "product": "Zip a dee doo dah", "desc": "F oq nfp gd r exbiikr wblkjm yumdd xy voqgt d hjtk. As sr ywvgiyb iqoibgm akron slfudtq smabx gj awlbtp ji vb do prvhlqq. ", "type": "Doodahs", "price": "3.99"}]
I'm trying to get the auto-complete to be based on the "product" entry.
Here is my code. It sends the request like it should, but I can't seem to get the auto-complete to populate the value based on 'product'. I'm sure I'm overlooking something stupid, but I've been staring at this for a few hours and figured its time to see if someone can help ;-).
Thanks for your help!
$(document).ready(function() {
$( "input[type='text']" ).autocomplete({
source: function( request, response ) {
$.ajax({
dataType: "json",
type : 'POST',
data: 'q=' + prepareInput(this.element.attr('name') + '=' + request.term),
success: function(data) {
$('input.suggest-user').removeClass('ui-autocomplete-loading');
return $.map( data, function(item) {
var r = $.parseJSON(data);
return {
label: r['product'],
value: r['product']
};
});
},
error: function(data) {
$('input.suggest-user').removeClass('ui-autocomplete-loading');
}
});
},
minLength: 3
});
});
--------------- Still not working, but current code below ------------------------
$(document).ready(function() {
$( "input[type='text']" ).autocomplete({
source: function( request, response ) {
$.ajax({
dataType: "json",
type : 'POST',
data: 'q=' + prepareInput(this.element.attr('name') + '=' + request.term),
success: function(data) {
$('input.suggest-user').removeClass('ui-autocomplete-loading'); // hide loading image
return $.map( data, function(item) {
console.log(item['product']);
return {
label: item['product'],
value: item['product']
};
});
},
error: function(data) {
$('input.suggest-user').removeClass('ui-autocomplete-loading');
}
});
},
minLength: 3
});
Console.log is currently writing out the proper value, but the auto-complete still isn't popping up.
--- Working Code Below - Finally Got it Running. Thanks #Robert --------------
I was missing a number of things:
1) It needs to be an array, so I added [].
2) Apparently the format needs to be assigned to "response".
Now its working...
$(document).ready(function() {
$( "input[type='text']" ).autocomplete({
source: function( request, response ) {
$.ajax({
dataType: "json",
type : 'POST',
data: 'q=' + prepareInput(this.element.attr('name') + '=' + request.term),
success: function(data) {
$('input.suggest-user').removeClass('ui-autocomplete-loading'); // hide loading image
return $.map( data, function(item) {
response([{
label: item['product'],
value: item['product']
}]);
});
},
error: function(data) {
$('input.suggest-user').removeClass('ui-autocomplete-loading');
}
});
},
minLength: 3
});

So you have an error on this line:
var r = $.parseJSON(data);
Post the output of console.log(data); //add this line bellow your success call
And change this line var r = $.parseJSON(data); to var r = $.parseJSON(item);

You are missing a single quote at end
prepareInput(this.element.attr('name'))
