Expand/Collapse table data - javascript

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.

JS function is not working when element clicked

first I'm going to explain the situation and then the problem.
I'm designing a table with some data and I developed some functions for ordering this data when the "th" tag of the column is clicked.
$('#table_id > thead > tr > th').click(function() ...
//ordering algorithm
In addition, I created 2 "select" tags for filtering the data of the tables. The method I'm using for filter data is to search for the text that matches the select text and use remove() method for deleting the row.
document.getElementById("select_id").addEventListener("change", function() {
//remove rows
When the data is filtered (by the select) and I try to click the "th" tag of the column the "click" method is not working and I have no error messages in the console, so I don't know how to solve it.
Any one knows is "click" method changes it's functionallity when the page content changes?
Thanks for reading.
If more code is needded for understanding the problem I will paste it.
If you are changing the DOM after page renders try using .on()
$(document).on('click', '#table_id > thead > tr > th', function() { ... });
This seems to be an issue with dynamically loaded elements.
It is a duplicate question and has been answered here:
Event handler not working on dynamic content
If the original th is removed from the DOM and then instead new th has inserted, the click event is no more assigned to it, so you need to re assign it.
another approach would be like what Nick Surmanidze suggested.

Highlight last inserted document in Meteor

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)

Cloned autocomplete input not working

I have a problem with jQuery function clone(). I think the problem is in the withDataAndEvents input parameter of this method.
Initially, I'm coding a table that has dynamic rows. I'm adding dynamically rows when clicking on a button put only in the first row. the first row contains initially many inputs fields and combo-boxes. Each field is initalized by an ajax call. And each action on a field leads to the refresh (filtering) on the whole fields of a row. I'm also using autocomplete on input fields.
The first row works perfectly. However, when cloning the tag:
If I did not enter values in the first row, the cloned and first row work fine
If I enter a value or values in first row fields and after I clone the , only the first row fields still work. In this case, if I try to change the value of the combo-boxe (which fire a change event for all concerned row fields), the fields of the first row are impacted despite using Ids when changing autocomplete data. Ids of fields, combo-boxes, table rows are dynamically created when clicking on the button to clone the widget.
The code I wrote is too long so I created a fiddle and simplified the case and still have the same problem.
I tried many suggestions that I've found like this, this one or this one in vain :-(
(data.('autocomplete', null), autocomplete("destroy") ...)
Do you have ideas about this issue ?
thanks in advance
Aside from the typo in the test (you are selecting by class instead of the new element by id), the basic problem is you are applying autocomplete before you add it to the DOM.
JSFiddle: http://jsfiddle.net/TrueBlueAussie/87jcw1y0/2/
I just reversed the order of these two lines:
$('.body').append(clone);
applyAutoComplete2('#myinput' + inc);
The cause... Some plugins use storage data associated with the DOM element, or attach events to ancestors etc. None of these can happen with a disconnected DOM element, so just attach it to the DOM first.
I think ur asking this
Check in this link http://jsfiddle.net/bsarunmca/87jcw1y0/3/
applyAutoComplete1('#myinput1');
$("button").click(function() {
inc = inc+1;
$('#myinput1').clone().attr('id','myinput'+inc).appendTo('.add-this');
$('#myinput'+inc).val('');
applyAutoComplete2('#myinput'+inc);
});

Remove row from JQuery DataTable - but it returns as soon as the table is redrawn. Is my .JSP data source the cause?

I have a button in each row, when pressed that row is removed from one table, and added to another table:
var row = $(this).closest("tr").remove().clone()
$('.my-other-table-class').append(row);
and at first it appears to work perfectly, the row is removed from one table and added to another, but when I force a re-draw (by changing the sorting of one of the columns, for example) all the rows are back as they were, and the buttons no longer work. This is the case for both the removed rows, and the rows added to the other table.
Is this because I'm using a .jsp table as a data-source? Would this work correctly if I dynamically added all the rows to the table using JavaScript at load-time, or if I used a modelMap collection as a data-source?
Thanks a lot for any advice.
Solution for future googlers - I have no idea how my google-Fu did not find the answer, I had all the right keywords!
In short:
I was doing this to add:
$('.my-other-table-class').append(row);
And this to remove:
var row = $(this).closest("tr").remove().clone()
but I should've been doing this add:
$('.my-other-table-class').dataTable().fnAddData([$(this).attr("data-val1"), "var2"]);
And this to remove:
$('.my-table').dataTable().fnDeleteRow($(this).closest('tr')[0]);
With more detail:
What I am really doing here is modifying the DOM with JQuery (well duh, but I'm really new at this, remember...) - I figured the DOM was the data-source for my table, so that made sense? The table is redrawn, it rereads the DOM and updates? Well not really.
In order to be dynamic, if you use DOM (in other words HTML, or in my case .jsp rendered as HTML) as your data-source, upon initialization, datatables will copy all that information into a JavaScript array.... so rather then my original thought:
"The DOM is not updating correctly, and that issues is propogating up in to my table... because HTML is static...or something?"
it turns out the actual problem was:
"I was updating the DOM, but the real data source was a JavaScript array I wasn't seeing. So upon redraw, this array was overwriting the DOM and my changes were being lost."
TL;DR: Use the Data-tables API and don't modify the data-source directly, unless you need to.
If the event handlers are one of the issues, it may help to set up your event handler like this:
$("#myTable").on("click", "button.moveMe", function(e) {
e.preventDefault();
var row = $(this).closest("tr").remove().clone()
$('.my-other-table-class').append(row);
});
This will set a handler on the table that has id="myTable". The handler will look for click events on buttons with the "moveMe" class. It will catch the event on rows that are added later, as well as the rows that exist when this hook is created.

Updating script to run for newly created table rows with incremented IDs

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:
