I have an html.erb file where I'm creating a new row as I iterate over a collection. I need to be able to dynamically create an id per row, and then be able to specify that id in my .js file so that I can show/hide some of its contents when clicked.
#foo.html.erb file
<table>
<thead>
<tr>
<th> Group Name </th>
<th> </th>
<th> Count </th>
</tr>
</thead>
<tbody>
<% #groups.each do |group_name, count_for_group| %>
<tr id="unique_id"> #create unique id here
<td> <%= group_name %> </td>
<td> </td>
<td> <%= count_for_group %> </td> #this should be hidden. If the row this data belongs to is clicked, then show it. If clicked again, then hide it.
</tr>
<% end %>
</tbody>
</table>
And then I need to be able to show/hide that group's count when clicked, but I don't know how to find an id that was dynamically created:
#app/assets/javascripts/test.js
$(document).ready(function(){
$("#dynamic_group_id").on(“click”, function(e){ #somehow be able to specify the dynamically created id
#show/hide contents
});
});
You are abusing element IDs. Use IDs for truly unique identifiers.
For everything else there are other selectors - the most commonly used are classes.
$(".group").on('click', function() {
$(this).find('.hide-me').toggle();
});
console.log($(".group"));
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<table>
<thead>
<tr>
<th>Group Name</th>
<th> </th>
<th>Count</th>
</tr>
</thead>
<tbody>
<tr class="group">
<td>The Beatles</td>
<td></td>
<td class="hide-me">4</td>
</tr>
<tr class="group">
<td>The Rolling Stones</td>
<td></td>
<td class="hide-me">4</td>
</tr>
</tbody>
</table>

When a cell is clicked the function is suppose to run.
Right now it is working only on the first row.
When i click on the button on a row i want that specific row to affect.
$(document).ready(function() {
function loadHistory() {
$('#btn').data('valType', 'more');
$('#btn').click(function() {
var id = $('#btn').data("valType")
})
}
})
In this case, use class selector, instead of id.
For example, yo have any list:
$(document).ready(function() {
$('.delete').click(function(e) {
$(this).parent().parent().remove();
})
})
<table>
<thead>
<tr>
<th>Number</th>
<th>Name</th>
<th>Action</th>
</tr>
</thead>
<tbody>
<tr>
<td>
1
</td>
<td>
Chair
</td>
<td>
<button class="delete">Delete</button>
</td>
</tr>
<tr>
<td>
2
</td>
<td>
Sofa
</td>
<td>
<button class="delete">Delete</button>
</td>
</tr>
<tr>
<td>
3
</td>
<td>
Table
</td>
<td>
<button class="delete">Delete</button>
</td>
</tr>
</tbody>
</table>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
Without the HTML code it is a bit more difficult to answer you, but I try.
Usually the ID is unique, so it's assigned to only one element, so try using the class selector.
Then another thing, I don't know if this is your case, if you go to create the other lines dynamically, the jQuery .click () function will not be able to manage the clicks on the elements created after loading the page. In this case use $.on('click', '.yourClass', function).
I hope I was helpful!
I have a list in a table that is alphabetically ordered like so.
<tbody>
<tr>
<th><strong>A</strong></th>
</tr>
<tr>
<td class="hide-me">Ants</td>
</tr>
<tr>
<td class="hide-me">Animals</td>
</tr>
<tr>
<td class="hide-me">Apples</td>
</tr>
<tr>
<th><strong>B</strong></th>
</tr>
<tr>
<td>Bars</td>
</tr>
<tr>
<td class="hide-me">Bats</td>
</tr>
<tr>
<td class="hide-me">Bananas</td>
</tr>
<tr>
<th><strong>C</strong></th>
</tr>
<tr>
<td>Cans</td>
</tr>
<tr>
<td>Cars</td>
</tr>
<tr>
<td>Cats</td>
</tr>
</tbody>
I use the $('table tr:has(td.hide-me)').hide() method to hide any of the elements that I don't want shown. However I also want to be able to hide the table headers if the table rows that contain normal table cells are hidden.
In the case above I would like to hide <tr><th><strong>A</strong></th></tr> because it has all of the following table rows hidden but not the the <tr><th><strong>B</strong></th></tr> because not all of the table rows are hidden.
I am relatively new to Jquery and am not sure how best implement conditional statements for a situation like this.
The first thing I did was put a class on the tr to indicate that that row contained a header. This makes it much easier to tell which rows are headers, rather than having to interrogate if they contain a th.
The second thing I did was change your hide expression for the .hide-me to find the hide me first, then find their parent trs, and hide them. This way the selector doesn't have to find the tr and check if each one has a hide me.
Then finally the logic finds all the headers, and shows them, so if any were previously hidden, they would be visible. It then filters the headers and only returns the ones that do not have any following trs that are not hidden. Havin the headers that do not have any visible following trs, it then hides them.
$('.hide-me').closest('tr').hide();
$('.header').show().filter(function(){
return $(this).nextUntil('.header').filter(':not(:hidden)').length < 1;
}).hide();

Hi there i have problem with Rails & Javascript. Here is my table in view.
<table>
<thead>
<tr>
<th>No</th>
<th>Name</th>
</tr>
</thead>
<tbody>
<tr id="adminrow">
<td>
1
</td>
<td>
John
</td>
</tr>
<tr id="adminrow">
<td>
2
</td>
<td>
Alex
</td>
</tr>
<tr id="adminrow">
<td>
3
</td>
<td>
Paul
</td>
</tr>
</tbody>
</table>
and my JS is
$('#select_name').click(function(event){
var username = $("#select_name").text();
console.log(username);
});
I have lot of names in my table, but JS printed first name in console. How can I print each name in the table to console?
You are creating in the each-loop N links (by the number of users) with the same select_name ID. Your javascript is confused, which one to choose. Try to add user id to your html select_name id and adjust your javascript accordingly. Same about your other id adminrow.
OR simply change your select_name to be a class and not id:
....
%a{:href=>"#", :class=>"select_name"}=u.firstname
....
$('.select_name').click(function(event){ ....
Ok, I am attaching the full code for you. For me it works just fine. E.g. prints just the name after clicking on the corresponding link:
<table>
<thead>
<tr>
<th>No</th>
<th>Name</th>
</tr>
</thead>
<tbody>
<tr class="adminrow">
<td>
1
</td>
<td>
John
</td>
</tr>
<tr class="adminrow">
<td>
2
</td>
<td>
Alex
</td>
</tr>
<tr class="adminrow">
<td>
3
</td>
<td>
Paul
</td>
</tr>
</tbody>
</table>
<script type="text/javascript">
$('.select_name').click(function(event){
var username = $(this).text();
console.log(username);
});
</script>
I am not such an expert in CSS;
My question is: can a div tag inherit dimensions from a table rows based on table row's class or id?
For example: We have a table with a couple of rows, but we don't know exact size of one table row, but we know the id/class of the rows. And by absolute positioning a div tag on table based on id/class to fill up 2 rows from start to end!
Can anyone point me to some addresses or to give me a tip code?
<table>
<col width="9%">
<thead>
<tr>
<th colspan="2"> </th>
</tr>
</thead>
<tbody>
<tr>
<th rowspan="2"> </th>
<td> </td>
</tr>
<tr>
<td> </td>
</tr>
<tr>
<th rowspan="2"> </th>
<td> </td>
</tr>
<tr>
<td> </td>
</tr>
</tbody>
</table>
I search for something like this:
You can take the width and height of parent td and then set them to the div using javascript.You want something like this?
https://jsfiddle.net/toLacq32/1/
$(document).ready(function(){
tdWidth = $('#inner-div').closest('td').width();
tdHeight = $('#inner-div').closest('td').height();
$("#inner-div").width( tdWidth ).height(tdHeight);
});
Ive got a table of data and on each row the there is a button, onclick im trying to 'copy' that rows data, and 'paste' it into another div.
Here's my HTML:
<table class="list">
<tr>
<th>Name</th>
<th>Number</th>
</tr>
<tr>
<td>Alpha</td>
<td>10</td>
<td>
<button id="addValues">Add</button>
</td>
</tr>
<tr>
<td>Beta</td>
<td>10</td>
<td>
<button id="addValues">Add</button>
</td>
</tr>
<tr>
<td>Charlie</td>
<td>10</td>
<td>
<button id="addValues">Add</button>
</td>
</tr>
<tr>
<td>Delta</td>
<td>10</td>
<td>
<button id="addValues">Add</button>
</td>
</tr>
</table>
<div id="selection">
<h4>Selections</h4>
<!-- SELECTED VALUES -->
</div>
Ive been trying to do this using:
$(function() {
$('addValues').click(function(){
var content = $('tr').html();
var newdiv = $("#selection");
newdiv.html(content);
$('#content').after(newdiv);
});
});
But cant quite get it to work, any ideas ?
Ive made a fiddle of the problem here - http://jsfiddle.net/9sZaX/2/
There are a few things wrong with your jsFiddle and/or code.
Don't use duplicate id attributes. It will cause unexpected results because jQuery will only select the first one found (which is expected, since there should only be one element with that id). Instead, give the <button>s a class attribute, like "addValues", and use this selector: $(".addValues").
Also, try setting the jsFiddle to actually use jQuery (set up on the left side of the page).
Another important problem was the fact that there is no element with the id of "content" on the page, so the .after() wasn't really doing anything.
Here's how I would set it up, depending on your actual requirements:
HTML -
<table class="list">
<tr>
<th>Name</th>
<th>Number</th>
</tr>
<tr>
<td>Alpha</td>
<td>10</td>
<td><button class="addValues">Add</button></td>
</tr>
<tr>
<td>Beta</td>
<td>10</td>
<td><button class="addValues">Add</button></td>
</tr>
<tr>
<td>Charlie</td>
<td>10</td>
<td><button class="addValues">Add</button></td>
</tr>
<tr>
<td>Delta</td>
<td>10</td>
<td><button class="addValues">Add</button></td>
</tr>
</table>
<div id="selection">
<h4>Selections</h4>
<!-- SELECTED VALUES -->
</div>
JS -
$(function () {
$(".addValues").click(function () {
var $this = $(this),
myCol = $this.closest("td"),
myRow = myCol.closest("tr"),
targetArea = $("#selection");
targetArea.append(myRow.children().not(myCol).text() + "<br />");
});
});
