I am trying to add a jquery filter to filter 2 related tables. The rows of each table share an ID, which I am trying to use to tie everything together. The filter works on one table at a time, but then I end up with 1 table filtered and the other not, or depending on my experimenting sometimes all the other rows are gone. Javascript is not my strong suit.
Here is a basic example of the structure:
<input id="myInput" type="text" placeholder="Search..">
<table id="table-a">
<tr>
<td data-resource-id="1">Adam</td>
</tr>
<tr>
<td data-resource-id="2">Bobby</td>
</tr>
<tr>
<td data-resource-id="3">Charlie</td>
</tr>
</table>
<table id="table-b">
<tr>
<td data-resource-id="1">Sandler</td>
</tr>
<tr>
<td data-resource-id="2">Knight</td>
</tr>
<tr>
<td data-resource-id="3">Brown</td>
</tr>
</table>
$(document).ready(function(){
$("#myInput").on("keyup", function() {
var value = $(this).val().toLowerCase();
$("#table-a tr").filter(function() {
$(this).toggle($(this).text().toLowerCase().indexOf(value) > -1)
});
});
});

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();

<tbody>
<tr class="header">
<th><strong>A</strong></th>

<td class="hide-me">Apples</td>

I have a 5x5 table, with each cell containing a word. When I click on the word, I want the color of the cell to be updated to a pre-defined color. In the example below, a table is set up with the colors encoded - what I want is them to be white until their corresponding word is clicked.
<TABLE BORDER="4" CELLSPACING="4" CELLPADDING="4">
<TR>
<TD BGCOLOR="#ffff00">Yellow</TD>
<TD BGCOLOR="#00ff00">Green</TD>
</TR>
<TR>
<TD BGCOLOR="#ff00ff">Purple</TD>
<TD BGCOLOR="00ffff">Blue</TD>
</TR>
</TABLE>
Using jQuery you could do this:
$('table td').on('click', function() {
$(this).attr("bgcolor", $(this).attr("data-color"));
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<TABLE BORDER=4 CELLSPACING=4 CELLPADDING=4>
<TR>
<TD data-color="#ffff00">Yellow
<TD data-color="#00ff00">Green
</TR>
<TR>
<TD data-color="#ff00ff">Purple
<TD data-color="00ffff">Blue
</TD>
</TR>
</TABLE>
For a larger project I'd recommend selecting the table by ID.
If you want to use vanilla Javascript you can add a simple onClick event listener and set the color. The color would need to be stored in a data-bgcolor attribute.
const tableCells = document.querySelectorAll('TD')
tableCells.forEach( function (cell) {
cell.addEventListener('click', function (e) {
e.target.style.backgroundColor = e.target.dataset.bgcolor;
})
})
<TABLE BORDER=4 CELLSPACING=4 CELLPADDING=4>
<TR>
<TD data-bgcolor="#ffff00">Yellow</TD>
<TD data-bgcolor="#00ff00">Green</TD>
</TR>
<TR>
<TD data-bgcolor="#ff00ff">Purple</TD>
<TD data-bgcolor="#00ffff">Blue</TD>
</TR>
</TABLE>
I'm working with the following HTML:
<tr class="oddrow">
<td>row1</td>
<td style="text-align:center;">
<table>
<tbody>
<tr>
<td width="50%">-1<br>+1</td>
<td width="50%">WSH: -110<br>SAC: -110</td>
</tr>
</tbody>
</table>
</td>
<td style="text-align:center;">
<table>
<tbody>
<tr>
<td width="50%">202.5</td>
<td width="50%">o: -110<br>u: -110</td>
</tr>
</tbody>
</table>
</td>
<td style="text-align:center;">WSH: 0<br>SAC: 0</td>
</tr>
<tr class="evenrow">
<td>row2</td>
<td style="text-align:center;">
<table>
<tbody>
<tr>
<td width="50%">-1<br>+1</td>
<td width="50%">WSH: -110<br>SAC: -110</td>
</tr>
</tbody>
</table>
</td>
<td style="text-align:center;">
<table>
<tbody>
<tr>
<td width="50%">202.5</td>
<td width="50%">o: -110<br>u: -110</td>
</tr>
</tbody>
</table>
</td>
<td style="text-align:center;">WSH: 0<br>SAC: 0</td>
<!-- The above line is the one I need. --!>
</tr>
There are 2 such rows (row1 and row2), alternating as an oddrow then evenrow. I have the entire HTML as a string in my JavaScript/jQuery code. I also have the information of the two three-letter abbreviations: in this example, WSH and SAC. What I need is the third <td style="text-align:center;"> of the row2 row. I should point out that there are several tables of row1 and row2 on the page, so I need a general selector. What I have been doing is just grabbing all the data in all the rows then parsing it from there, but the inconsistency of the data is making that more difficult. Is there a quick and dirty jQuery that will point me to the data I need?
I was thinking something like $("tr td:contains(" + abbrev + ") td:contains('row2')").text();, but that doesn't get it.
Can anyone help?
Your hierarchy in your selector is wrong, tds with the abbreviation are not an ancestor to the tds with the text of "row2"
You also need to ensure you have apostrophes around your abbrev variable.
Can you try:
$("tr td:contains('row2') td:contains('" + abbrev + "')").text()
Any chance you can add semantic classes instead? These sorts of selectors are gnarly to maintain.
I have a table structure like:
<table id='myTable'>
<thead>
<tr>
<th class='name'>Name</th>
<th class='nick-name'>Nick Name</th>
<th class='age'>Age</th>
</tr>
</thead>
<tbody>
<tr>
<td class='name'>Ilona</td>
<td class='nick-name'>Baby Doll</td>
<td class='age'>21</td>
</tr>
<tr>
<td class='name'>Sieraa</td>
<td class='nick-name'></td>
<td class='age'>24</td>
</tr>
<tr>
<td class='name'>Britney</td>
<td class='nick-name'>Blondie</td>
<td class='age'>27</td>
</tr>
<tr>
<td class='name'>Kate</td>
<td class='nick-name'>Night Queen</td>
<td class='age'>19</td>
</tr>
<tr>
<td class='name'>Dani</td>
<td class='nick-name'></td>
<td class='age'>23</td>
</tr>
<tr>
<td class='name'>Aliee</td>
<td class='nick-name'></td>
<td class='age'>26</td>
</tr>
<tr>
<td class='name'>Brandi</td>
<td class='nick-name'></td>
<td class='age'>27</td>
</tr>
</tbody>
</table>
As some Nick Name fields are empty, I want to display the value of Name in Nick Name if they are empty.
Eg: In Second Row of Table Body, The Nick Name field is empty, The Name field contains Sierra. So, I want to display Sierra in Nick Name field instead of leaving it empty.
How can I achieve this using jQuery or JavaScript
jQuery:
this only works when the .name is always the exact previous element of .nick-name like in your structure
$('.nick-name').each(function () {
if ($(this).text().length === 0) {
$(this).text($(this).prev().text());
}
});
This works when both .name and .nick-name have the same parent
$('.nick-name').each(function () {
if ($(this).text().length === 0) {
var name = $(this).parent().find('.name').text();
$(this).text(name);
}
});
You should read up on DOM Traversing with jQuery, there is lots of stuff you can do to get to your elements.

This should help
$('#myTable tr').each(function(){
var nickname = $(this).find('.nick-name').html();
alert(nickname);
});

I have a table with a few rows... I want to be able to select a row and click on modify and I should be able to make all the cells of that row editable...
How would I make a cell editable in Javascript? And is it better to use Jquery?
There's no need to do your own code, a plugin for jQuery for this very purpose exists already. Try jEditable, it can do exactly what you need.
Their demo page has some nice examples:
http://www.appelsiini.net/projects/jeditable/default.html
Setcontent-editable property of each element you want to edit.
http://html5demos.com/contenteditable
Here's a quick concept I just worked up for you:
$(function(){
$("button[name='doModify']").click(function(){
// disable out modify button
$(this).attr("disabled","disabled");
// enable our save button
$("button[name='save']").removeAttr("disabled");
// cycle through each row having marked for modification
$(":checkbox[name='modify']:checked").each(function(){
$(this).closest("tr").find("td:gt(0)").each(function(){
// convert each cell into an editable region
$(this).wrapInner("<textarea name='"+$(this).attr("rel")+"'></textarea>");
});
});
});
});
--
<table border="1" cellspacing="1" cellpadding="5">
<tbody>
<tr>
<td><input type="checkbox" name="modify" /></td>
<td rel="username[]">jon.doe</td>
<td rel="information[]">This is my bio.</td>
</tr>
<tr>
<td><input type="checkbox" name="modify" /></td>
<td rel="username[]">jonathan.sampson</td>
<td rel="information[]">This is my bio.</td>
</tr>
<tr>
<td><input type="checkbox" name="modify" /></td>
<td rel="username[]">yellow.05</td>
<td rel="information[]">This is my bio.</td>
</tr>
<tr>
<td colspan="3" align="right">
<button name="doModify">Modify</button>
<button name="save" disabled="disabled">Save</button>
</td>
</tr>
</tbody>
</table>
You can insert textboxes inside each cell and set the values to be that of the table cell.
Something like this
$(function(){
$("#tbl1 tr").click ( function(){
if ( !$(this).hasClass('clicked') )
{
$(this).children('td').each ( function() {
var cellValue = $(this).text();
$(this).text('').append ( "<input type='text' value='" + cellValue + "' />" );
});
$(this).addClass('clicked');
}
});
});
<table id="tbl1">
<tr>
<td>1</td>
<td>4</td>
<td>3</td>
</tr>
<tr>
<td>4</td>
<td>5</td>
<td>6</td>
</tr>
</table>
You can then place an update button and fetch the values from the textboxes and update.
