jQuery or JavaScript getting the value of .each function - jquery-ui

I have this jQuery .each function so I can traverse all the UL hmtl tags. Then I will get there id attribute. But the problems is, How can I get each value and place it to another variable so I can use it to .sortable UI function. Here is my code:
jQuery('.b ul').each(function(){
jQuery(this).attr('id');
});
example: the output of the .each function when I do alert is "0 1 2". How can I place it to another variable? So it would be use in:
jQuery(variable here).sortable(){ });
The code above will get the ID attribute. Anyone who can help?
Thanks,
Justin

No need to use the ID's at all. You can provide jQuery's $() function with more than just ID's:
$('.b ul').sortable();
Or if you are using multiple libraries (jQuery, MooTools, etc.):
jQuery('.b ul').sortable();

Any of these should work
Save the jquery array to a variable to act on later:
var $lists = $(".b ul")
$lists.sortable()
Act on the selector directly:
$(".b ul").sortable()
Don't do this:
var ids = []
$(".b ul").each(function() {
var id = $(this).attr("id")
ids.push(id)
})
var selector = "#" + ids.join(", #")
$(selector).sortable()

Convert Select2 input to tokens

Does the Select2 jQuery plug-in have a built-in function for converting strings to tokens?
I want to be able to call this tokenizing function when the user pastes strings into a Select2 field so that the pasted input becomes tokens.
I think I have solved the question myself with the following code:
// force tokenizing of Select2 auto-complete fields after pasting
$('body').on('paste', '.select2-input', function() {
// append a delimiter and trigger an update
$(this).val(this.value + ',').trigger('input');
});
This assumes that commas are set as delimiters in the plug-in's "tokenSeparators" initialization setting.
For 4.0.1 version:
$('#my-select').data('select2').dataAdapter.$search.val("tag1,tag2,").trigger("input");
This will add two tags: tag1 and tag2 (note trailing ,).
Important: you should add data: [] into select2 init parameters.
Use an input type text, and assign the select2 to it. Like
<input type="text" id="makeTokens" />
and then in javascript
$("#makeTokens").select2({
placeholder: "Paste data",
tags: ["red", "green", "blue"],
tokenSeparators: [",", " "]
});
in the tags, you can assign any values that you want it to display as select options and use the tokenSeperators to seperate the text on commas or spaces etc.
Note: The resultant input value will be comma seperated tokens.
For some reason Donald's solution didn't work for me (maybe newer versions of select2 behaves differently). This is what worked for me:
$('body').on('paste', '.select2-input', function (e) {
var pasteData = (e.originalEvent || e).clipboardData.getData('text/plain') || '';
$(this).val(pasteData + ',');
e.preventDefault();
});
Since at the point the event was triggered the value of .select2-input was an empty string, I extractacted the pasted string from the event object. Apparently the default select2 for copying action was still triggering after this, so I had to add e.preventDefault(); to stop it from running and messing up the input.
just run this jQuery which takes the separatoes from options.tokenSeparators directly, and applies for all select2 instances in the page automatically:
$(document).on('paste', 'span.select2', function (e) {
e.preventDefault();
var select = $(e.target).closest('.select2').prev();
var clipboard = (e.originalEvent || e).clipboardData.getData('text/plain');
var createOption = function (value, selected) {
selected = typeof selected !== 'undefined' ? selected : true;
return $("<option></option>")
.attr("value", value)
.attr("selected", selected)
.text(value)[0]
};
$.each(
clipboard.split(new RegExp(select.data('select2').options.options.tokenSeparators.map(function (a) {
return (a).replace(/[\-\[\]\/\{\}\(\)\*\+\?\.\\\^\$\|]/g, "\\$&");
}).join('|'))),
function (key, value) {
if (value && (!select.val() || (select.val() && select.val().indexOf('' + value) == -1))) {
select.append(createOption(value));
}
});
select.trigger('change');
});

How to display previous value on Min Miles text field

I want to display a previous value on Min Miles and that should not be editable. I want like
Default value of Min Miles is 0.
When I click on Add More Range then In the new form - Min Value should be Max Value of Previous Form.
I am using semantic form for. Please Help Me. How can I do this...
Regarding your second question, and assuming that the new form appears through javascript, without page reloading, you can grab the
field value with javascript and use it as the default value for the
new field. The "add new range"
Something Like
function getvalue(){
var inputTypes_max = [],inputTypes_min = [],inputTypes_amount = [];
$('input[id$="max_miles"]').each(function(){
inputTypes_max.push($(this).prop('value'));
});
$('input[id$="amount"]').each(function(){
inputTypes_amount.push($(this).prop('value'));
});
var max_value_of_last_partition = inputTypes_max[inputTypes_max.length - 2]
var amount_of_last_partition = inputTypes_amount[inputTypes_amount.length - 2]
if (max_value_of_last_partition == "" || amount_of_last_partition == "" ){
alert("Please Fill Above Details First");
}else{
$("#add_more_range_link").click();
$('input[id$="min_miles"]').each(function(){
inputTypes_min.push($(this).prop('id'));
});
var min_id_of_last_partition=inputTypes_min[inputTypes_min.length - 2]
$("#"+min_id_of_last_partition).attr("disabled", true);
$("#"+min_id_of_last_partition).val(parseInt(max_value_of_last_partition) + 1)
}
}
I have Used Jquery's End Selector In a loop to get all value of max and amount field as per your form and get the ids of your min_miles field and then setting that value of your min_miles as per max_miles
It worked For me hope It works For You.
Default value of a field can just be passed in the form builder as a second parameter:
...
f.input :min_miles, "My default value"
Of course I do not know your model structure but you get the idea.
Regarding your second question, and assuming that the new form appears through javascript, without page reloading, you can grab the field value with javascript and use it as the default value for the new field. The "add new range" click will be the triggerer for the value capture.
Something like (with jQuery):
var temp_value = '';
$('#add_more_range').click(function(){
temp_value = $('#my_form1 #min_miles').value();
$('#my_form2 #max_miles').value(temp_value);
});
Again I am just guessing the name of the selectors, but the overall approach should work.
If you are also adding dinamically to the page the "Add new range" buttons/links, then you should delegate the function in order to be inherited also for the so new added buttons:
$('body').on('click', '#add_more_range', function(){...});

Processing multiple select controls within jquery mobile form

I am trying to process multiple input selects in a form each one has a unique name and id.
here is my first try, this is broken when y = value.val(); executes
var selects = $("#pmWorkOrderProcedureStepsForm").find('select');
$.each(selects,
function(index, value)
{
y = value.val();
});
I can see in chrome debug that value has a reference to something that looks like
HTMLSelectElement#select-choice-400139826
Where select-choice-400139826 is my first select input name.
How do I get just the name and the selected value of the input from here.
New to jquery mobile!
You can use the following code snippet:
var selects = $("#pmWorkOrderProcedureStepsForm").find("select");
$.each(selects,function(){
name = $(this).attr('name');
value = $(this).val();
});

Let me know if that helps.

Autocomplete is returning undefined

This is my jquery function:
$(function() {
$("#user").autocomplete({
source: 'spiderman/null/users.php',
minLength: 2
});
});
And when I start typing a minimum 2 letters in my
<input type="text" class="highlight" id="user" name="user"/>
It is showing a item list saying "undefined".
Seems like it is a invalid source, but I'm pretty sure it is valid, since I've maked include_once in the same dir, and the source script was loaded.
Here is my PHP code:
if( !$_GET['term'] ) {
die();
}
$return_arr = array();
$ac_term = "%".$_GET['term']."%";
$query = "SELECT `name` FROM `users` WHERE `name` LIKE :term";
$result = $conn->prepare($query);
$result->bindValue(":term", $ac_term);
$result->execute();
/* Retrieve and store in array the results of the query.*/
while ($row = $result->fetch(PDO::FETCH_ASSOC)) {
$row_array['name'] = $row['name'];
array_push($return_arr, $row_array);
}
/* Toss back results as json encoded array. */
echo json_encode($return_arr);
I've tested the PHP code also, and it works well: as for the term lol it does returned:
[{"name":"LolShit"},{"name":"Lolipop"},{"name":"Lolo"},{"name":"Lolololololololo"},{"name":"Loll"},{"name":"Pro Lol"}]
I think you either just want your JSON array to look like this:
["LolShit","Lolipop","Lolo","Etc..."]
Or if you want to use an object provide a label and value (which UI autocomplete expects):
[{"label":"LolShit","value":"LolShit"},{"label":"Lolipop","value":"Lolipop"},...]
I've added
$row_array['value'] = $row['name'];
And it worked... Dammit.
I hope it's ok to answer own question, lol.

how do i iterate the tables parameters which is present under the main table?

In lua ,im calling a function which returns a table variable that contains many parameter internally..but when i get that value i couldnt access the paramter which is present in the table. I can see the tables parameter in the original function in the form of
[[table:0x0989]]
{
[[table:0x23456]]
str = "hello"
width = 180
},
[[table:0x23489]]
{
str1 = "world"
}
it shows like this.but when it returns once i can able to get the top address of table like [[table:0x0989]]..when i tried acessing the tables which is present inside the main table.it is showing a nil value...how do i call that ?? can anyone help me??
If I'm reading it correctly you're doing this:
function my_function ()
--do something
return ({a=1, b=2, c=3})
end
From that you should be able to do this:
my_table = my_function()
then
print(my_table.a) --=> 1
print(my_table.b) --=> 2
print(my_table.c) --=> 3
