I am a newbie of using fancytree. I have created a demo to display data in a table within a webpage. Now I hope to collect the data back after users updated them.
I was using so called tree methods as mentioned in the tutorial. There is an example that has two lines below:
var tree = $("#tree").fancytree("getTree");
alert("We have " + tree.count() + " nodes.");
I thought I can use the fancytree instance, the variable 'tree' in the above example, to access all nodes so that to collect the values they take. But when I put this two-lines example into my codes, I got errors.
For making it clear, I pasted the complete code below. Close to the end of the code, there are two comments marked by Place_1 and Place_2. When I put the two-lines example in each of these two places, I got errors, which are "Uncaught TypeError: undefined is not a function", or "Uncaught Error: cannot call methods on fancytree prior to initialization; attempted to call method 'getTree'" respectively.
I thought I must missed something. Any idea will be helpful. Thanks!

Thanks for the suggestion from Chase.
I think the two-lines example should be added into somewhere after the initialization has been finished.
For example, I added the codes into a button's body and it works well. Here is the example about implementing a button in fancytree: http://wwwendt.de/tech/fancytree/demo/#sample-source.html

I am working on an input field that is autocompleted with names from this link(steam API):
http://api.steampowered.com/ISteamApps/GetAppList/v0002/?format=json
or
http://api.steampowered.com/ISteamApps/GetAppList/v0001
I would also like the field to return the id of the game despite the name being insered into it.
So far after browsing the forums I put together this but it doesn't quite work:

For the autocomplete part I chose to use jQuery autocomplete function: https://jqueryui.com/autocomplete/ however I am open to other methods.
Edit: Fixed syntax error on line 31 but the code still isn't working.
JSFiddle: https://jsfiddle.net/vxej2L5g/
In the success block you are assigning a label and id. In the label you have assigned name, and in id the appid. We can modify this to format the label like this:
success: function (data) {
var transformed = $.map(data, function (el) {
return {
label: el.appid + " - " + el.name,
id: el.appid
};
});
response(transformed);
},
There is a syntax error in your Javascript on line 31 (basically you have an extra closing parenthesis and semicolon).
The JSON response for the API you are calling wraps the list of apps.
I'm a newbie to jQuery, so, please, don't judge me for my dumb question.
What I'm trying to achieve is fill datatable with exchange rates, sourced by API.
So, I managed to construct datatable, but its body is empty and there're no errors in the console, it's just "loading..." message where my data is supposed to be.
Searching for similar topics just didn't get any results. I would be thankful for your help, because I'm banging my head against that wall for 2 days already.

Seems like your data is structured improperly. Each data entry must correspond to DataTables row, so your code should be something like:
var key = '8366e7a49e014c729111a0ac6e5c7d9d';
var url = 'https://openexchangerates.org/api/latest.json?app_id=';
var dataTable = $('#rates').DataTable({
sDom: 't',
ajax: {
url: url+key,
dataSrc: function(data){
let apiData = [];
$.each(data.rates, function(index, entry){
apiData.push({currency:index, rate:entry});
});
return apiData.slice(0,10);
}
},
columns: [
{title:'currency', data:'currency'},
{title:'rate', data:'rate'}
]
});

I need to get data from Materialize CSS chips, but I don't know, how.
$('.chips-placeholder').material_chip({
placeholder: 'Stanici přidíte stisknutím klávesy enter',
secondaryPlaceholder: '+Přidat',
});
function Show(){
var data = $('.chips-placeholder').material_chip('data');
document.write(data);
}
<!-- Added external styles and scripts -->
<script type="text/javascript" src="https://code.jquery.com/jquery-2.1.1.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/materialize/0.97.7/js/materialize.min.js"></script>
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/materialize/0.97.7/css/materialize.min.css">
<link href="http://fonts.googleapis.com/icon?family=Material+Icons" rel="stylesheet">
<!-- HTML body -->
<div class="chips chips-placeholder"></div>
<button onclick="Show()" type="button">Show</button>
So, to access to the data's chip you just have to do this:
var data = $('#id of your chips div').material_chip('data');
alert(data[0].tag);`
'0' is the index of your data (0, 1, 2 , 3, ...).
'tag' is the chip content. You can also get the id of your data with '.id'.
To get data from Materialize CSS chips, use the below code.
$('#button').click(function(){
alert(JSON.stringify(M.Chips.getInstance($('.chips')).chipsData));
});
They appear to have changed the method available in the latest version.
The documentation suggests that you should be able to access the values as properties of the object, but I’ve spent an hour looking, not getting anywhere.
Until the following happened
$('.chips-placeholder').chips({
placeholder: 'Enter a tag',
secondaryPlaceholder: '+Tag',
onChipAdd: (event, chip) => {
console.log(event[0].M_Chips.chipsData);
},
During the onChipAdd event I was able to access the event. Within this object was an array of tags.
I know this isn't the documented way, however there is only so much time a client will accept when it comes billing and I must move on.
This worked great for me
<script type="text/javascript">
document.addEventListener('DOMContentLoaded', function() {
var elems = document.querySelectorAll('.chips');
var instances = M.Chips.init(elems, {
placeholder: "Ajouter des Tags",
secondaryPlaceholder: "+tag",
onChipAdd: chips2Input,
onChipDelete: chips2Input,
Limit: 10,
minLength: 1
});
function chips2Input(){
var instance = M.Chips.getInstance(document.getElementById('chip1')), inpt = document.getElementById('myInputField');
inpt.value = null;
for(var i=0; i<instance.chipsData.length; i++){
if(inpt.value == null)
inpt.value = instance.chipsData[i].tag;
else{
inpt.value += ','+instance.chipsData[i].tag; //csv
}
}
console.log('new value: ', inpt.value);
}
});
</script>
I am not able to figure out why remove tab is not invoked when I use ng-click but it works fine in non Angular way! I referred help available in http://docs.telerik.com/kendo-ui/controls/navigation/tabstrip/how-to/AngularJS/add-new-tabs-dynamically.html.
I have written code in dojo.telerik.com/#datha_k/oNuBI. I'm clueless here, tried a lot, please help.
I think my issue related to this discussion at http://www.telerik.com/forums/use-angularjs-directive-in-tab-content 'The tabstrip widget does not support angularjs binding expressions'. Any work around to suggest?

The problem with your code are 2-
1)Either use jquery or ANgular for components or else u will face anonymous behaviour.I have corrected your code for appending tabs in angular kendo.
2)You have to call ng-click from content attribute and not text attribute of kendo-tabstrip
When using list.js and tabletop for a sortable table taken from a Gdoc, I get the error: "Uncaught TypeError: Cannot read property 'childNodes' of undefined" on the first line of list.js.
Because the website I work for can only have JS uploaded, I need to write all my html using js or jquery, so it's a bit wonky. I think the error is being thrown because of the order I have everything, but I have tried moving things around to no avail. Everything is working other than the sorting.
Thanks!

JS file
var options = {
valueNames: [ 'university', 'no' , 'no2' , 'rank']
};
var userList = new List('tablesetter', options);
The problem
var userList = new List('tablesetter', options); should be executed when the dom has an element of the list class; since in the question's code the list class default to list" , so such element should be <tbody class="list"> that is going to be appended to the #tablesetter only when the showInfo function receive data from google.
The solution
We ensure that the var userList = new List('tablesetter', options) statement executes after ( ie: at the end ) of the showInfo function; in other words move var userList = new List('tablesetter', options); from options.js just before the closing right bracket of the showinfo function.
More details
in the question's code when list.js tries to init() the dom is:
and list.list is still undefined when list.js defines it's getItemSource() functions:
with the proposed fix, at the var userList = new List('tablesetter', options); the dom is like:
and when defines it's getItemSource() functions the list.list can use the tbody as aspected:
If you look at this post, I'm sure your just missing some of the minimum requirements for list.js to function properly. Try to dynamically add the input with id and class of "search" as well with your other classes. Let me know if this helps.
