Is it possible to flip/reverse td values of a table.
If I fx: put a class on the td section I want flipped and name it 'valuesToFlip'
$('.valuesToFlip').reverse() // not working.
reverse() can be used with array, to convert it to array use get() and apply reverse(). Now for updating the order append back them using append()
var $td = $('.valuesToFlip');
$td.parent().append($td.get().reverse());
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<table>
<tr>
<td class="valuesToFlip">1
</td>
<td class="valuesToFlip">2
</td>
<td class="valuesToFlip">3
</td>
</tr>
</table>

I'm trying to do the following: I have a table populated with data from the DB. Apart from that, I have an input where you can write something and a button that will filter, only showing the lines that have that string. This is working now!
The thing is, the input should only allow you to filter by foo.name/foo.code (two propertys of my entity).
I'm adding the code I have in case anyone can guide me out, I've tried several things but this are my first experiences with JQuery while I have a strict story-delivery time. Thanks everyone!
<tbody>
<c:forEach var="foo" items="${foo}">
<tr id = "fooInformation" class="mtrow">
<th id="fooName" scope="row">${foo.name}</th>
<td id="fooCode" class="left-align-text">${foo.code}</td>
<td class="left-align-text">${foo.country}</td>
<td class="left-align-text">${foo.region}</td>
<td class="left-align-text">${foo.subregion}</td>
</tr>
</c:forEach>
</tbody>
$("#search").click(function () { -> button id
var value = $("#fooRegionSearch").val(); -> value of the input
var rows = $("#fooRegionTable").find("tr"); -> table id
rows.hide();
rows.filter(":contains('" + value + "')").show();
});
To start with, your HTML is invalid - there cannot be elemenets with duplicate IDs in HTML. Use classes instead of IDs.
Then, you need to identify which TRs pass the test. .filter can accept a callback, so pass it a function which, given a TR, selects its fooName and fooCode children which contain the value using the :contains jQuery selector:
$("#search").click(function() {
var value = $("#fooRegionSearch").val();
var rows = $("#fooRegionTable").find("tr");
rows.hide();
rows.filter(
(_, row) => $(row).find('.fooName, .fooCode').filter(`:contains('${value}')`).length
).show();
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<table id="fooRegionTable">
<tr id="fooInformation" class="mtrow">
<th class="fooName" scope="row">name1</th>
<td class="fooCode" class="left-align-text">code1</td>
<td class="left-align-text">${foo.country}</td>
<td class="left-align-text">${foo.region}</td>
<td class="left-align-text">${foo.subregion}</td>
</tr>
<tr id="fooInformation" class="mtrow">
<th class="fooName" scope="row">name2</th>
<td class="fooCode" class="left-align-text">code2</td>
<td class="left-align-text">${foo.country}</td>
<td class="left-align-text">${foo.region}</td>
<td class="left-align-text">${foo.subregion}</td>
</tr>
</table>
<button id="search">click</button><input id="fooRegionSearch" />
I would like to have keyup function that would show only rows matching the input text by cell that spans on multiple rows.
Consider following table:
<table border='1'>
<tr>
<td rowspan='2'>Key1</td>
<td name='Key1'> dummy1 </td>
</tr>
<tr>
<td name='Key1'> dummy2 </td>
</tr>
<tr>
<td rowspan='2'>Key2</td>
<td name='Key2'> dummy3 </td>
</tr>
<tr>
<td name='Key2'> dummy4 </td>
</tr>
</table>
jsfiddle
Here each row has second td tag with name that matches its "parent" column text. So when I type 'Key1' at the input field I would like it to show only dummy1 and dummy2. Is it possible in jquery?
I understand that you want to display the rows that has a matching name. If this is wrong, please elaborate more, then I can update it.
Here is a demo: https://jsfiddle.net/erkaner/gugy7r1o/33/
$('input').keyup(function(){
$('tr').hide();
$("td").filter(function() {
return $(this).text().toLowerCase().indexOf(keyword) != -1; }).parent().show().next().show();
});
});
Here's my take on your issue, assuming you always want the first column to show. https://jsfiddle.net/gugy7r1o/2/
<input type="text" id="myInput" />
<table border='1'>
<tr>
<td rowspan='2'>Key1</td>
<td name='Key1' class="data"> dummy1 </td>
</tr>
<tr>
<td name='Key1' class="data"> dummy2 </td>
</tr>
<tr>
<td rowspan='2'>Key2</td>
<td name='Key2' class="data"> dummy3 </td>
</tr>
<tr>
<td name='Key2' class="data"> dummy4 </td>
</tr>
</table>
.data{
display:none;
}
var theData = $('td.data');
var input = $('#myInput').on('keyup', function(){
theData.hide();
var value = input.val();
var matches = theData.filter('[name="'+value+'"]');
matches.show();
});
Firstly, I would recommend using <ul> to wrap each key in as tables should be used for data structure (Forgive me if that is what it is being used for).
Secondly, just attach an on keyup event to the search box and then find matches based on the id. See example below:
JS Fiddle Demo
It is also worth mentioning that it could be useful attaching a timeout to the keyup event if you end up having large amounts of rows so that only one filter is fired for fast typers!
Here is the code I want to process using javascript / jquery
EDITED THE BELOW CODE BLOCK FOLLOWING THE COMMENTS
<table>
<tbody>
<tr class="promote">
<td>1</td>
<td><span class="team_logo visible-lg visible-sm" style=""></span><a class="team_name " href="/team/show/7473/Power-Hiters">Power Hiters</a><span class="online" title="user is online"></span></td>
<td style="text-align:center">5</td>
<td style="text-align:center">10</td>
<td style="text-align:center">5</td>
<td style="text-align:center">0</td>
<td style="text-align:center">0</td>
<td style="text-align:center">6.713</td>
</tr>
<tr> <!-- Similar Above tr Content --> </tr>
<tr> <!-- Similar Above tr Content --> </tr>
<tr> <!-- Similar Above tr Content --> </tr>
</tbody>
</table>
I want to get the inner content/html of each <td> tag in a array using javascript / jquery
Extra Info:
When I tried it seems jquery strips the td and tr tags.
Actual thing I want to do is extract td in a multi dimensional array for each tr
the table structure:
<table>
<tbody>
<tr> <!-- Above tr Content --> </tr>
<tr> <!-- Above tr Content --> </tr>
<tr> <!-- Above tr Content --> </tr>
</tbody>
</table>
Since you want a multidimensional array, you will need to:
Make an array that will hold all table data
Iterate through all tr and create an array per row
Push that array in the first one, that holds all table data.
something like this:
var tableContent = [];
$('table tr').each(function(){
var trcontent = [];
$('td', this).each(function(){ trcontent.push($(this).text()); });
tableContent.push(trcontent);
})
console.log(tableContent);
example in jsfiddle
Try,
var arr = $("#cache").find('td').map(function(){ return this.textContent; }).get();
I have a pretty basic table at the moment:
I need to be able to only hightlight one row in each column, and deselect whatever was selected before it..
I understand I'm going to need a CSS class, e.g.
.hightlighted {
background: #f00;
color: #fff;
}
The HTML in the view is pretty basic also:
<tbody>
<tr>
<td> </td>
<td>Differdange</td>
<td> </td>
</tr>
<tr>
<td> </td>
<td>Dippach</td>
<td> </td>
</tr>
<tr>
<td> </td>
<td>Dudelange</td>
<td> </td>
</tr>
<tr>
<td> </td>
<td>Echternach</td>
<td></td>
</tr>
<tr>
<td> </td>
<td>Erpelscheid</td>
<td> </td>
</tr>
<tr>
<td> </td>
<td>Esch-sur-Alzette</td>
<td> </td>
</tr>
<tr>
<td> </td>
<td>Esch-sur-Sûre</td>
<td> </td>
</tr>
<tr>
<td> </td>
<td>Ettelbruck</td>
<td> </td>
</tr>
<tr>
<td> </td>
<td>Feulen</td>
<td> </td>
</tr>
</tbody
But I don't know whether it's appropriate to highlight/unhighlight rows in CSS if I am going to be needing to 'grab' the selected data from the rows when the table is completed by the user?
Can anyone suggest what I should use (JQuery, Javascript, CSS) to highlight a row in a column so that I can get the data later?
EDIT
Now I've got the highlighting sorted, the only problem I'm having is differentiating between columns so that instead of this (which I'm getting atm)
I want each columns to be able to have it's own unique row highlighted (e.g. Differdange could be highlighted, as well as dddd on Localities)
Any way to edit the
$("tr").click(function() {
$("tr").removeClass("highlighted");
$(this).addClass("highlighted");
});
code to do this? Thanks
You can use the .removeClass() and .addClass() jQuery methods to achieve this. Here's a little demo: little link. The code is pretty self-explaining, but here's a commented version of the JavaScript part:
var chosen = []; //an array to save the chosen row for each column
$("td").click(function() { //when a td is clicked
var idx = $(this).index() + 1; //get column of current cell
$("td:nth-child(" + idx + ")").removeClass("highlighted"); //unhighlight all cells in column
$(this).addClass("highlighted"); //highlight this one
chosen[idx] = $(this).parent("tr").index(); //and save it as chosen in its column
});

Demo
Hi now you can do this jquery as like this
Css
.hightlighted{
background: #f00;
color: #fff;
}
jquery
$("tr").click(function(){
$("tr").removeClass('hightlighted')
$(this).addClass('hightlighted');
});
Could you be more precise on when and how the selection should be made? I'm guessing you want the user to click on a row, which then gets highlighted. In that case you'd want to create a highlight class in css, add it to the row the user clicked on and later you can get the row cia its class:
tr.highlighted td {
background: #f0;
color: #fff;
}
And in the javascript:
// catch click event
$('tr').click(function (e) {
// remove prvious selection
$('tr.highlighted').removeClass('highlighted');
// make this row selected
$(e.currentTarget).addClass('highlighted');
});
// get current selection
function getSelected () {
return $('tr.highlighted');
}
I have been working on this and cannot get this iterator to work. I have the following HTML and am trying to iterate through all rows (except the first row) and extract the values in cells (td) 2 and 3 :
<div id="statsId">
<table width="220" cellspacing="0" cellpadding="0" border="0">
<tbody>
<tr>
<td width="65"/>
<td width="90"/>
<td width="65"/>
</tr>
<tr style="font-weight: bold;">
<td align="left">$1.00</td>
<td>
UserID1
</td>
<td>Single</td>
</tr>
<tr>
<td align="left">$6.99</td>
<td>
UserID2
</td>
<td>Multiple</td>
</tr>
<tr>...
.....(snip)
I tried the following iterator to iterate through all except the first row of the table that is a child of "div#statsID" and get the values of the 2nd and 3rd cells (in the example, the first extracted cells would have values of "UserID1" and "Single"), but it doesn't work.
$('div#statsId > table tr:not(:nth-child(1))').each(function(i, ele) {
var secondCol = $('td:nth-child(2)', ele).innerHTML
var thirdCol= $('td:nth-child(3)', ele).text()
.....
});
Any suggestions on how to specify and iterate through the rows (except the first) of a table that is a child of a div would be appreciated.
$("#statsId > table tbody tr:not(:first)").each ( function() {
var secondCol = $(this).find('td:nth-child(2)').html();
var thirdCol= $(this).find('td:nth-child(3)').text();
});
Note
You can use the id selector independently. No need to use the tag name.
There is no innerHTML for a jQuery object. Use html() instead
