I have form and list of objects at the same page. When I insert a new row, it is not very easy to see where the newly inserted row is placed. Therefore, I thought I could color/highlight the newly inserted row (and perhaps remove the highlight after a few seconds).
How can I do this? I think a way to do this could be using a method on the server which returns the inserted id (return Collection.insert(doc);) and on the client use a callback with
Meteor.call('insertDoc', function(err,result) {
// do something with result
});
I think I can use a reactive-var to save the id of the last inserted row and in the loop highlight the row with
{{#each docs}}
<li class="{{isActive}}">{{name}}</li>
{{/each}}
and have a helper to return active if this._id equals the reactive var with the last inserted id.
But is this the best way to do it? How can I remove the color after some seconds? I have seen such behaviour on many pages but I cannot find any tutorials/code snippets to achieve this.
I wrote a package that uses Meteor's UI hooks to fade items in and out of a list as they are added and removed, to help users maintain context as data changes:
https://github.com/mizzao/meteor-animated-each
There is a demo at http://animated-each.meteor.com/. You can see that as items are added and removed, they are faded in and out. If items are inserted off the screen, the visible area does not scroll.
This isn't doing exactly what you want, but you can use the same idea to highlight items as they appear as well, as opposed to the simple fade in.
Note that all of this happens at the UI rendering level - not the template/code level. The UI hooks are also not well documented right now, but they've been around for a while.
I don't know if your method is the best, but that's how I'd go about doing it.
As for the animation, I'd use a CSS3 animation. Plenty to choose from ( https://developer.mozilla.org/en-US/docs/Web/CSS/animation ), and you can easily make them fade to the standard color. The animation would also only be applied to the last inserted item (because of the way you did it, only the last item would have the "active" class)

I have a use case in which I want the following things:
Fill the dropdown with predefined elements
Make a fetch and pull some additional elements when the menu gets opened (emulated with a setTimeout and a Promise in my demo)
Make it possible to create new elements by typing inside the dropdown without filtering the currently shown elements
"1" and "2" are easy to implement, but adding "3" to the mix seems impossible.
As soon as I start typing, the "Create new" element shows up, and everything else is filtered.
Demo: https://codesandbox.io/s/react-select-v3-sandbox-forked-x3qy2?file=/example.js
It seems that this should be possible by using the filterOption={() => true} prop in order to avoid elements to get filtered / hidden, but in practice it doesn't seem to be working.
How can I stop select2 from filtering the current elements?
I've started a deep dive in to HTML + CSS + JS for the past couple of days and I'm curious to know is it possible to expand and collapse rest of the table data if I click my first table data on my table row.
I've tried myself using multiple combinations but couldn't succeed so I wanted to understand is it really possible or I have to improve further :)
Thanks!

If I click on say - AUSDe451 or AUSDe441, rest of the corresponding columns should be either expand or collapse[i.e LAMP 6.93817139 & 51_REGALIA 456.352] should expand/collapse if I click - AUSDe451]
Your click handler is a bit wrong!
When you're handling clicks on the .server-name element, $(this) inside the function refers to the item that has been clicked, in this case the .server-name table row.
When you run $(this).find(...), you're looking for child elements of the table row, which do not exist. So rather than use $(this).find(...), you should probably be looking elsewhere in the DOM.
Also, you seem to be searching for span elements, which don't exist anywhere in your HTML markup, so that part of the function will never return anything anyway.
I'm not sure whether I'm using the right terminology here - but here is an example:
https://gist.run/?id=57ed46429e4583eb4c3fb11814451a55
This is how it looks like in Chromium:
Basically, the entries on top (red outline) are a visualization of an array as the "first-level" data display; here one can toggle each element's selection, and make a multi-element selection (red background). The array that is the source of the "first-level" display is mydata in first-level-items.js.
Those items that are selected in "first-level", are then shown again in "second-level" (green outline); here the same information of name and value is displayed, although a bit differently. Here also one can toggle an elements selection - but only one "second-level" element can be selected. The array that is the source of the "second-level" display is myseldata in second-level-items.js.
The intent here, is that once a "second-level" selection has been made, a slider appears, to change the .value property of the particular object which is the selected array element.
My original question (which is why I started this post/example at all), was:
How do I ensure that whenever the slider is changed, the value is updated in both second-level and first-level display?
... however, for reasons beyond me, this in fact does work somewhat in this gist.run example (but it still doesn't work in my actual project, which forced me to come up with the example to begin with). Also it only works somewhat, in the sense that when loading the example page at first, after making first and second level selections, and then changing the slider, the .value will be updated in both first- and second-level display. But as soon as I try deselecting on second level - or changing the selection on second level - then updating stops. So, I guess this question still stands...
After a second-level selection has been made, deselecting on second level (by clicking to toggle) does NOT remove the slider; how can I have it behave like that?
The update happens only on the slider's onChange - basically, while you drag and slide, this component emits onSlide, but it will generate onChange only at the end when the mouse is released (that is, when the sliding has stopped). How can I update both first- and second- level display while the slider is sliding?
And finally - is this how this kind of a problem is best addressed in Aurelia? That is - I currently have one array in first-level-items.js; first-level-items.js then has a singleton reference to second-level-items.js, so it can call a method within it, to change a filtered copy of the array on the second level, which then serves as a source both for second-level display and the slider... Is there a better way to organise this?
Boy, this was a pain, but here's what I think is the solution:
https://gist.run/?id=c09fea3b82a9ebc41e0a4c90e8665b04
Here are some notes:
Apparently, there is something wrong applying if.bind or show.bind on the input element of the slider - instead, the input element should be put in an enclosing div, and the div should have if/show.bind applied
Furthermore, if.bind should not be used, as it re-instantiates the slider element - use show.bind so we can get a reference to the slider widget at start already, even if it is hidden
Seemingly, using TaskQueue in attached() is the only way to get a reference to the slider at start
Once we have a reference to the widget, re-apply it on each second level element, whenever they change
Do not set this.myselChanging to null to specify no target of the slider (simply count on hiding the slider appropriately)
For a continuous change (onSlide), simply use this.myselChanging.value = e.value; in the handler - both first-level and second-level values will be changed
Beyond this, it seems arrays are copied by reference, so the multi-level update happens without further intervention...
Though, would still love to know what is the proper way to do this...
I have a element that I am trying to update on each creation of an item.
At the moment, a list is populated via a REST API, and I have a script that takes some info from each item, counts another table, and the answer is to populate the counter bubble of the jquerymobile list.
I have searched, and I understand I need to access 'ui-li-count' but I am unable to get to it. I have searched on here and tried many ways, but none actually give me the answer.
Using google console, this is how the element is drawn:
This is how it should look
This is the code I am trying, and failing badly :
console.log('get count : '+$('li[name=mobilelistitem_9]').find("ui-li-count ui-body-b").text());
I need to set the value, but here I am trying to find it, so I know what syntax to use to set the value.
I need this to fire, each time a new item is added to the list collection. Using $(this) or Appery(this) is not working.
Any suggestions on this would hugely welcomed :)
Thanks in advance.
add a . (dot) in the find filter for both the classes, and leave no spaces between them:
$('li[name=mobilelistitem_9]').find(".ui-li-count.ui-body-b").text())
you are searching for a class, that's why you need the dot. No white space = "both classes"
FIDDLE http://jsfiddle.net/z2zJL/1/
I stole the fiddle from ezanker comment, and modified it a bit: as you can see only the 2nd list item will return a result.
I've got a table with the type ahead feature from jQuery UI. It is working with my form when there is only 1 table row (initial view). There's a button to allow the user to create additional table rows as required which also increments the IDs for the text inputs and select menus.
There's another script that inserts a matching value into the select menu based on the typeahead selection. Both of these work fine for the first row, but stop working for any additional Rows that are created.
I've setup a sample JSFiddle:
http://jsfiddle.net/fmdataweb/hxzME/1/
I think I understand why they only work for the first row - they are tied to these IDs: #lastYearSelect1 and #nextYearSelect1 - but I'm not sure how to change them so they then work with #lastYearSelect2, #nextYearSelect2, #lastYearSelect3, #nextYearSelect3 and so on.
There's a few problems with the script.
Firstly you're right, you need to setup all the scaffolding again after you clone the row, the clone method will not copy the functionality, just the html elements.
To find the right element you can use the JQuery ^= selector, which matches the start of an attribute name, on the on the clone object to find the right child input to turn into an autocomplete field. You can do the same trick in the function to change the dropdown to the correct function.
Finally a lot of your code and variables were in the wrong scope to be accessible properly. I've moved a lot of the vars around so they're accessible, mainly into the global scope. When you're a bit more experienced you won't want to do this, but for now this is fine.
I also created a new function setDropDown, but this code is almost identical to what was there before.
Here is a working version of your code:
