Can I get the list of Caman.js filters?

Is there any way to return the list of all the built-in filters within the library.
For example:
var caman_Default_List = [];
Caman('myCanvas', function(){
caman_Default_List= this.getAllFilters();
});
For now I'm using this and it works okay:
var filters =
[
"vintage", "lomo", "clarity", "sinCity", "sunrise",
"crossProcess", "orangePeel", "love", "grungy", "jarques", "pinhole",
"oldBoot", "glowingSun", "hazyDays", "herMajesty", "nostalgia",
"hemingway", "concentrate"
];
myList.push(filters[ some filters ]);
Caman("#myCanvas", function(){
this[myList[index]]().render();
});
But I was wondering if there is a way to get the values of the filters without delcaring them customly. (eg. list = [ "vintage", "lomo", ......... ])

I was looking through their docs, but could not find anything helpful for the data you are trying to get. I took a look at their code and came up with the below for you.
I am not sure I would 100% trust the code, because the order of properties might change, but at least it gives you what you wanted.
console.log(Object.keys(Caman.prototype).slice(75, 93))
<script src="https://cdnjs.cloudflare.com/ajax/libs/camanjs/4.1.2/caman.full.min.js"></script>

I used the code below to achieve what I wanted as #AndrewLohr stated:
//Declare lists to store filter names
var list4,list5,list6,list7 = [];
//Get Caman Filters (Samples : "vintage", "clarity", ... )
list4 = (Object.keys(Caman.prototype).slice(75, 93));
list5 = list4.toString().toUpperCase(); //To upper Case as string value (use as Label Button Name)
//Get Caman Filters (Customs : "brightness", "saturation")
list6 = Object.keys(Caman.prototype).slice(45, 55);
//Add some more elements in the list
list6.push("clip", "stuckBlur", "exposure", "noise", "sharpen");
list7 = list6.toString().toUpperCase(); //To upper Case as string value (use as Slider Name)
//Print lists
console.log(list4);console.log(list5);console.log(list6);console.log(list7);

ng-repeats, showing record while it's value is a part of field of another object

I've got objects 'ing' with a field named 'id' and another one called 'fObj' with a field named 'contain'.
By using ng-repeat i'd like to show only these 'ing' objects where ing.id is a part of fObj.contain
e.g.
ing=[{id: 1,field: value},{id:2, field: othervalue},{id:3, field: cat}];
fObj={field1: value1, field: value2, contain: ':1:3:'};
By having this contain value I'd like to show only ing's with id=1 and id=3
Yeah, I know there are two types of data (number and string) but even if i changed numbers to strings it still didn't work
I just dont't know how to make it works. It's probably some kind of custom filter, but I've tried couples and nothing happend.
I would be glad if you suggest me a solution.
Thanks

In your controller,
var ids = fObj.contain.split(':');
// the array for your ng-repeat
var displayIng = [];
// loop the objects, see if the id exists in the list of id's
// retrieved from the split
for(i = 0; i < ing.length; i++) {
if(ids.indexOf(ing.id.toString()) displayIng.push(ing[i]);
}

I would split the numbers out of fObj.contain; and use them as hashmap object keys for simple filtering of the array
var ing=[{id: 1},{id:2},{id:3}];
var fObj={contain: ':1:3:'};
var IDs = fObj.contain.split(':').reduce(function(a,c){
a[c]=true;
return a;
},{});
// produces {1:true,3:true}
var filtered = ing.filter(function(item){
return IDs[item.id];
});
console.log(filtered)

How to fetch existing JSON that exists in data-attr and update that

In the given fiddle , click on Addons buttons and on selection and unselection
of Checkboxes , i am trying to update the data-attr
array present as data-stuff .
Once i set the data how can i fetch the existing and update it with new data .
http://jsfiddle.net/kgm9o693/9/
// checkbox checked
$(document).on('click', '.ui-checkbox-off', function (event) {
var vendoritemsdata = $(".lastItm_Wrap").data('stuff');
var checkboxid = $(this).next().attr("id");
var cost = $(this).attr("cost");
var toppcrusts = [];
toppcrusts.push({
'name': checkboxid,
'cost': cost
});
if (vendoritemsdata.length == 0) {
$('.lastItm_Wrap').attr('data-stuff', toppcrusts);
}
else {
var existingdata = $('.lastItm_Wrap').data('data-stuff');
}
});
Could you please tell me how to resolve this ??

You are trying to use the DOM as a variable. It should be the other way around. Use the DOM only to show results (total cost in your case). But before that keep everything into an array serialize the array if you need it as json or data-stuff.
Examine the example at the bottom of this http://api.jquery.com/serializeArray/
If you want to keep doing it your way, convert the data to JSON and use this:
Set data
$('.lastItm_Wrap').attr('data-stuff', JSON.stringify(toppcrusts) );
Get data
var existingdata = JSON.parse( $('.lastItm_Wrap').attr('data-stuff') );

JS and ExpressionEngine - Remove KV pairs by duplicate values only?

We're building a site with ExpressionEngine. We are running a SQL query to gather up all member IDs for a specific member group. After that, we are using EE tags to get data from a custom member field for each member ID.
The ID and field data need to stay paired, as we will be populating a drop-down so that the ID is the value and the field data is the text, so we are currently putting them into a JS array as key/value pairs. The call is as follows:
var array= [
{exp:query sql="SELECT * FROM exp_members WHERE group_id = 5"}
{exp:member:custom_profile_data
member_id="{member_id}"}
{if company != ''}
{{member_id}:"{company}"},
{/if}
{/exp:member:custom_profile_data}
{/exp:query}
};
This gives us the output:
var array = [
{1:"name01"},
{2:"name02"},
{3:"name01"},
{4:"name03"}
];
Now, our problem. We need to remove objects based on duplicate field data (values) only, so the above array would look like this:
var array = [
{1:"name01"},
{2:"name02"},
{4:"name03"}
];
None of these IDs (keys) will ever be the same, but the field data (values) can be. So we want to keep the first KV pair that comes through with a unique value, but remove any subsequent dupes of that value - despite the fact that they will not be true "duplicate values" due to a different ID (key).
Keeping in mind that the KV pairs are all dynamic, is there any possible way to do this via JS so we can create a new array for the cleaned data to pass to the drop-down?

You could handle the duplications by modifying your MySQL query. (In my example, my custom field ID was 1.)
var myArray = [];
{exp:query sql="SELECT MIN(m.member_id) AS co_member_id, d.m_field_id_1 AS company FROM exp_members m INNER JOIN exp_member_data d ON m.member_id = d.member_id WHERE d.m_field_id_1 != '' AND m.group_id > 0 GROUP BY d.m_field_id_1;"}
myArray.push({{co_member_id}: "{company}"});
{/exp:query}
This query would use the first (in the ordinal sense) member_id found; you could also change the MIN to MAX and get the last.
This will give you a clean output in your source, without the need for any additional JS processing. I'd also recommend changing the names of the variables you're outputting as to not conflict in EE's parsing.

I would do it like...
function removeDups(arry){
var tmp = {}, retainIdx=[], newArry=[];
arry.forEach(function(obj, idx){
var val = obj[Object.keys(obj)[0]];
if(val && !tmp[val]){
retainIdx.push(idx);
tmp[val] = true;
}
});
retainIdx.forEach(function(i){
newArry.push(arry[i]);
});
return newArry;
};

How to replace ' / ' with '-' inside ObservableArray ? Knockout js

Well i am trying to pass an observable array via ajax call to my controller but i get every value there except date . i get something like '01-01-01' etc .
I found the issue but unable to fix that as i dont know how to replace / with - .
My ObservableArray have around 10 list items each list item holds a many properties out of those startDate holds the date like ("23/10/2014") . i just need something like ("23-10-2014") .
Tought of posting my function's and more i hope thats not required in this case i believe .
Let me explain with bit of code and sample data :
function myarray()
{
var self=this;
self.startDate=ko.observable("");
self.name=ko.observable("");
self.place=ko.observable("");
}
MyObservableArray :
self.Main= ko.observableArray();
In between i do some stuff to load Data into self.Main and i am sending self.Main to controller having data like below :
self.Main[0] holds :
startDate() -->gives you "23/10/2014" //individual observables inside onservable array
name() --> "jhon"
place()--> "croatia"
Likely
self.Main[9] holds :
startDate() --> "29/05/2012"
name() --> "pop"
place()--> "usa"
I am trying like i want to alter the self.Main() and replace the startDate and use the same self.Main to send to my controller . Once after replacing in self.Main when i check date the / should be replaced with - .
Possible solution : i can use a different observable array and push all the VM's of Main into it but i am trying to do on self.Main without using other .
If someone can show some light it is much appreciated .

What I got that you are facing problem in escaping / in replace.
Try this
"(23/10/2014)".replace(/\//g,"-") //returns "(23-10-2014)"
I tried something for you using simple JS
var arr = [{date:"(23/10/2014)"},{date:"(23/10/2014)"},{date:"(23/10/2014)"},{date:"(23/10/2014)"}];
arr.forEach(function(obj){obj.date = obj.date.replace(/\//g,"-")});
console.log(arr) //will print date field as "(23-10-2014)" for all objects.

One solution would be to add a computed value that returns the array with the right values.
self.Main = ko.observableArray([...values here...]);
self.MainComputed = ko.computed(function() {
var computedArray = [];
self.Main().forEach(function(item) {
var newItem = myarray(); //Create a new item.
newItem.name(item.name());
newItem.place(item.place());
newItem.startDate(item.startDate().replace(/\//g,"-"));
computedArray.push(newItem);
});
return computedArray;
});
Then use the computed value in the places where you need the values with -.
I can think of two other ways to solve your issue, when taken into account that you want to use self.Main:
Replace the / with - before setting startDate on your item.
Change startDate to a computed value while storing the original value in another variable.
The first solution should be pretty straight forward (provided that it is a valid solution).
The second solution would look something like this:
function myarray()
{
var self=this;
self.originalStartDate = ko.observable("");
self.name = ko.observable("");
self.place = ko.observable("");
self.startDate = ko.computed(function() {
if(self.originalStartDate()) {
//We can only replace if the value is set.
return self.originalStartDate().replace(/\//g,"-");
}
else {
//If replace was not possible, we return the value as is.
return self.originalStartDate();
}
});
}
Now when you set the values you do something like:
var item = myarray();
item.originalStartDate = "01/01/2014";
Then when you get the value of startDate you would get "01-01-2014".

I haven't used Knockout.js but you can do this with a Javascript replace:
var str = [your array value] ;
var res = str.replace("/", "-");
