Applying css to the table row dynamically created with Vue.js - javascript

So I have table, where rows are created dynamically using v-for:
<table>
<tr><th class='name'>Name</th><th>Surname</th></tr>
<tr v-for='data in datas'><td class='name'>#{{data.name}}</td><td>#{{data.surname}}</td></tr>
</table>
And then, using jQuery, I want to hide the column with class 'name', but when I make
$('.name').hide();
Only header disappears. I suppose it's because the row is made dynamically, but how could I handle this?
I've tried:
making each() function on all elements with this class,
writing script like .css('display','none'), not hide()
but it didn't help. Strange, but alert() in each() fires each time it should, but hide() ignores added elements
More concrete data:
the table itself:
<table class="striped bordered responsive">
<thead>
<tr><th class="stat-table-creatives" colspan="2">Creative info</th><th>Impressions</th><th>Clicks</th><th>CTR</th><th>CPC</th><th>Price per unit</th><th>Sum</th><th class="stat-table-date">Date</th></tr>
</thead>
<tbody>
<tr v-for="stat in stats"><td class="stat-table-creatives">#{{ stat.creativeTitle }}</td><td class="stat-table-creatives">#{{ stat.creativeType }}</td><td>#{{ stat.impressions }}</td><td>#{{ stat.clicks }}</td><td>#{{ stat.ctr }}</td><td>#{{ stat.cpc }}</td><td>#{{ stat.client_price }}</td><td>#{{ stat.sum }}</td><td class="stat-table-date">#{{ stat.date }}</td></tr>
</tbody>
</table>
function called on button click
getJsonForStats: function(filters){
if((filters[0]=='creative')||(filters[1]=='creative')){
$('.stat-table-creatives').show();
} else {
$('.stat-table-creatives').hide();
}
if((filters[0]=='date')||(filters[1]=='date')){
$('.stat-table-date').show();
} else {
$('.stat-table-date').hide();
}
});
The function is called from another function, which is called on v-on:click

jQuery works just fine with Vue dynamically created table. Check this fiddle: https://jsfiddle.net/crabbly/9o69f2yr/
I believe the problem will be on how your application is loading, your filters, etc.
Depending on how you are trying to access the table rows, you may want to make sure that DOM is completely updated before querying it. You can use Vue's nextTick (http://vuejs.org/api/#Vue-nextTick).
Inside your Vue method, before you try to hide the rows, in your example, calling getJsonForStats method, you can do
this.$nextTick(function() {
//DOM updated and ready to rock and roll
this.getJsonForStats(..your filter params...);
}

suppose it's because you use the same class for <th> and <td>
try <th class="name-th"> and then $(".name-th").hide(); $(".name").hide();
maybe it will help
UPD:
I don't know.. this code is working perfectly:
<table id="tab" border='1'>
<tr><th class='name'>Name</th><th>Surname</th></tr>
<tr><td class='name'>n</td><td>s</td></tr>
</table>
<input id="click" type="button" value="Hide" />
js:
$(document).ready(function(){
$("#click").click(function(){
$("#tab").find(".name").hide();
});
});

DataTables: TypeError: i is undefined

I have a table like the following
the table as rowspans because for some users I need to have 2 lines (Like you see at column 'D')
I am trying to use datatables:
<table class="table table-bordered table-hover table-striped" id="myTable">
(...)
</table>
And I call this at the begining of the code:
<script>
$( document ).ready(function() {
$('#myTable').DataTable();
});
</script>
But I have this error:
TypeError: i is undefined
And the table is not like a datatable type!
Maybe it doesn't work with rowspans?
Any idea??
FWIW you can also get this error if you don't have the same number of <td></td> elements in every row. Make sure you aren't adding any rows with nav buttons or links or anything like that that may not be formatted the same way as the other rows.
jQuery DataTables plug-in doesn't support ROWSPAN attribute by default. However there is a RowsGroup plugin for jQuery DataTables that groups cells together to make them look like as if ROWSPAN attribute is used.
See this example for code and demonstration.
See jQuery DataTables – ROWSPAN in table body TBODY for more details.
For future referer.
It is because you are using Rowspan or colspan which is not supportable.
If you want to use colspan you can use it outside </tbody>.
Thanks.
This problem happens if your table is not well formed, for example you should have
<table>
<thead>
<th>
<tbody>
<tr>
<td>
And then the id of the table should not overlap with id of any thing else on the same page. Other wise you will get errors like i is udefined or c is undefined.
I'd say your table is not a data table because you have undefined data and the 'i' referred to is the internal iterator of the DataTable loop, the use of rowspans is the problem - I would redesign your table to have an entire row for each piece of data (in your example 250 would require an entire row with duplicate values for all other columns except D) - it is wholly possible to use css to hide values that are duplicated for the same visual effect, this would allow datatable filtering to still work on those rows (although you may need some hooks to reveal hidden data when these 'extra' rows are filtered).
I was facing the same issue. The main reason for the error is due to using the colspan & rowspan. Because the jQuery DataTables plug-in does not support them and hence causing the error.
TypeError: i is undefined
So, If you are using any colspan or rowspan within any <tr></tr> inside the <tbody></tbody> then make sure that each <tr></tr> having the same no of <td></td> for each row. If not, then repeat the <td style='display:none'></td> to match the same no e.g
<table border='1' cellspacing='2'>
<thead>
<tr>
<td>A</td>
<td>B</td>
<td>C</td>
</tr>
</thead>
<tbody>
<tr>
<td rowspan="2">1</td>
<td rowspan="2">name</td>
<td>200</td>
<td style='display:none'></td>
<td style='display:none'></td>
</tr>
<tr>
<td >300</td>
<td style='display:none'></td>
<td style='display:none'></td>
</tr>
</tbody>
</table>
I think by following the above suggestion will help you sure.

jQuery- Hide table -> After reloading page,my table shows up for couple seconds

I have problem with my table.I use jQuery function .hide().
$("#table").hide();
And that works perfectly, but there is one problem.After reloading page, my table shows up for couple seconds and then hide.
I have been trying many things, i put .hide() function first in list but still nothing.
I used $("#table").css("display", "none"), but still i have same problem.
What should i do?
You could do something like,
Add style to table For Example,
<table id="table" style="display: none">
<thead>
<tr>
<td>Name</td>
</tr>
</thead>
<tbody>
<tr>
<td>Thiru</td>
</tr>
</tbody>
<table>
You do not need to use jQuery to hide content on load, just use display: none.
#table {
display: none;
}
To answer to your question, I you are using hide() into a $(document).ready(function() {}). So it is executed after your page is fully loaded.

JavaScript - Get data of first cell of selected table row

<table border="1" cellpadding="5" id="newtable">
<tr>
<th>Room No</th>
<th>AC</th>
<th>Deluxe</th>
<th>Tariff</th>
</tr>
<c:forEach var="room" items="${myrooms}">
<tr bgcolor="#4B476F" onMouseOver="this.bgColor='gold';" onMouseOut="this.bgColor='#4B476F';">
<td class="nr"><c:out value="${room.roomno}" /></td>
<td><c:out value="${room.ac}" /></td>
<td><c:out value="${room.deluxe}" /></td>
<td>₹<c:out value="${room.price}" /></td>
<td><button type="button" class="mybutton" onclick="rowFunction()">Pay</button> </td>
</tr>
</c:forEach>
</table>
On clicking the button corresponding to every row, I want my script to return the Room number i.e. the first cell data of the row. I have tried a lot of things after referring various articles on the Internet. Nothing seems to work. Please help.
You can use something like
Demo
$(window).on('click', '.mybutton' ,function() {
alert($(this).parent().parent().find('.nr').text());
//Or you can use, which is even better
//alert($(this).parent().siblings('.nr').text());
});
Here, the selector is pretty simple, we are first binding click event on the button, and onclick we select the button element parent i.e td and we select the parent of td i.e tr and later we find an element with a class of .nr
You can also write td.nr instead of just .nr to be more specific.
Your rows are being dynamically added, in order for your click listener to work you will have to delegate the events
Credits to #Patsy Issa for suggesting .siblings()
$(".mybutton").click(function(){
alert($(this).parent().siblings().eq(0).text());
});
usually im using DataTables js for solution, you can check at: https://datatables.net/reference/api/row().data()

removing inner table filter bootstrap

I have a filterable table containing a collapsible list in a column. The collapsible contains another table. Sample of the situation.
The problem is that when anything is written to filter only the required items, the inner table also gets filtered. Is there a way to avoid this.
Suggestions about how else to display something like this are also welcome.
If you want to filter only from the Name column, you can try to use below code:
$('#filter').keyup(function () {
var stringValue = $(this).val();
$("#outer-table tr.row").each( function( index ) {
$(this).hide();
$(this).find(".panel-title a:contains("+stringValue+")").parents("tr").show();
});
});
EDIT: I have tested the new code above, it works as expected.
HTML changes, easier to get ONLY every <tr> that are part of your outer-table:
Change your outer-table tag from <tbody class="searchable">, into this, <tbody id="outer-table" class="searchable">
Then add a selector to every <tr> inside outer-table but NOT inside inner-table, like this:
</tr>
<tr class="row">
<td><div id="collapsibleMain2" class="panel-group">
</tr>
<!-- and so on -->

jquery grid and javascript best practice

Im new to jquery and need some help.
I have written a table that act like a grid with help from jquery.
When a user click on Name column the user will be redirected to the details page.
Now I want to know if I can do this in a better way?
And should the JS code be in the page or in a separated JS file?
Here is the code.
<table id="grid">
<thead>
<tr>
<th data-field="name">Namn</th>
<th data-field="location">Ort</th>
<th data-field="phone">Telefon</th>
<th data-field="buildinmonth">Bygga inom</th>
<th data-field="houselot">Har tomt</th>
<th data-field="created">Skapad</th>
</tr>
</thead>
<tbody>
#foreach (var item in Model)
{
<tr>
<td><span id="open" data-id="#item.Id">#item.Name</span></td>
<td>#item.Location</td>
<td>#item.Phone</td>
<td>#item.BuildInMonth</td>
<td>#item.HouseLot</td>
<td>#String.Format("{0:d}", item.CreatedDate)</td>
</tr>
}
</tbody>
</table>
<script>
$("#grid").kendoGrid({
scrollable: false,
sortable: true
});
$("#grid #open").click(function () {
window.location.replace("/lead/details/" + $(this).data("id"));
});
</script>
In this scenario, dont need to use any jquery click event, when the html table is loading that time we can give a <a> tag like,
<td>#item.Name</span></td>
When a user click on Name column the user will be redirected to the details page. Now I want to know if I can do this in a better way?
This seems ok. The only thing I feel can be adde to this is on hover of the Name column, you can show a tooltip of "Show more details" or something more intuitive.
And should the JS code be in the page or in a separated JS file?
Yes I always prefer to have all my JS code in a seperate file. The advantage of doing so is that you can minify the JS code later on.
