I am able to delete the duplicates from table all columns,but I want to delete duplicate cell values from only first column.
Orginal Output
Remove duplicates from total table getting output as
I want this
Script
var seen = {};
$('#test td:first-child').each(function() {
// Encode column and content information.
var key = $(this).text();
if (seen[key]) {
$(this).text('');
}
else {
seen[key] = true;
}
});
Fiddle Demo
Explanation:
$('#test td:first-child') This helps to select only the first Row of the Table
Use this code it is working fine.
var seen = {};
$('#test td').each(function() {
// Encode column and content information.
var key = $(this).index() + $(this).text();
if (seen[key] && $(this).index()==0) {
$(this).text('');
}
else {
seen[key] = true;
}
});

I have a table with a lot of rows in it, and I want to give users the ability to click an 'A' button and all the results that start with 'A' are displayed. They could do the same for every letter. This is what I've come up with so far:
HTML
<input type="button" id="aSort" value="A" onclick="alphaSort(this.value);">
<table>
<thead>
<tr>
<td>Title</td>
<td>Description</td>
<td>Active</td>
</tr>
</thead>
<tbody>
<tr>
<td name="title">Apple</td>
<td>It's a fruit</td>
<td>Active</td>
</tr>
<tr>
<td name="title">Pear</td>
<td>It's also fruit</td>
<td>No</td>
</tr>
</tbody>
</table>
JS
function alphaSort(val) {
//pseudocode
var $rows = $('td[name=title]');
$rows.forEach(function(e) {
if(e.innerText == val + '%') {
e.closest('tr').show();
} else {
e.closest('tr').hide();
}
}
}
So with what I have here, the idea is if the user clicked the button only the Apple row would show. Ideally the function would be case insensitive. Could someone help me with how to properly iterate through all the table rows efficiently and compare the value stored in the title row?
you can use startsWith function : https://www.w3schools.com/jsref/jsref_startswith.asp
like this :
$("#aSort").click(function(){
var $rows = $('td[name=title]');
var val = $(this).val()
$rows.each(function() {
if($(this).text().startsWith(val)) {
$(this).closest('tr').show();
} else {
$(this).closest('tr').hide();
}
})
})

This Fiddle Example shows a comparison table that dynamically shows information in a column when a button is clicked. Once the table is filled up, I want to start the whole process again. But as the example shows, the buttons are stuck at adding information to th:nth-child(2) and td:nth-child(2) during the second time instead of moving on to the next column like during the first time.
I'm guessing this part needs some change if( allCells === fullCells ) { to keep information being added to next columns.

var area = $(this),
filltable ='',
button = $(this).find('button'),
buttontext = button.text();
button.on("click",function(){
var allCells = $('table').find('th,td').length;
var fullCells = $('table').find('th,td').filter(function() {
return $(this).text() != '';
}).length;
if( allCells === fullCells ) { // If table is full
$('table').find('th,td').not(':first-child').removeClass('addinfo');
filltable();
}
else { // If table isn't full
filltable = function(){
var i = $('th.addinfo').length !== 0 ? $('th.addinfo:last').index() : 0;
console.log( i );
i + 2 > $('th').length ||
$('th,td').filter(':nth-child(' + (i + 2) + ')')
.addClass( 'addinfo' ).html(buttontext);
}
filltable();
}
}); // end button on click function
});
});
Please see the attached link for demo. I have created a function name cleartable() which clears the table if its full and have used your old filltable() function to repopulate. There is repetition of code which you will have to clean up.
th:nth-child(2) identifies second child of th.
td:nth-child(2) identifies second column.
Similarly if you wanted to do something with let say second row, you can use tr:nth-child(2).
I hope this helps you understand a little about parent-child relationship in jquery.
JSFIDDLE DEMO
function clearTable() {
$('table th:nth-child(2)').html('');
$('table th:nth-child(3)').html('');
$('table th:nth-child(4)').html('');
$('table td:nth-child(2)').html('');
$('table td:nth-child(3)').html('');
$('table td:nth-child(4)').html('');
}
http://jsfiddle.net/jqVxu/1/
I think you'd better to count th only. count all td and th make me confused.
$(function () {
function filltable(buttontext) {
var i = $('th.addinfo').length !== 0 ? $('th.addinfo:last').index() : 0;
i + 2 > $('th').length || $('th,td').filter(':nth-child(' + (i + 2) + ')')
.addClass('addinfo').html(buttontext);
}
$('.area').each(function () {
var area = $(this),
button = $(this).find('button'),
buttontext = button.text();
button.on("click", function () {
var allCells = $('table').find('th').length-1;
var fullCells = $('table th.addinfo').length;
console.log(allCells, fullCells);
if (allCells === fullCells) { // If table is full
$('table .addinfo').removeClass('addinfo');
filltable(buttontext);
} else { // If table isn't full
filltable(buttontext);
}
});
});
});
I have a table in below format,
<table>
<tr>
<td>Dynamic Text1</td>
</tr>
<tr>
<td> </td>
</tr>
<tr>
<td>Dynamic Text2</td>
</tr>
<tr>
<td>Dynamic Text3</td>
</tr>
<tr>
<td> </td>
</tr>
</table>
I want to get the last td containing something other than just a . In the example markup shown this would be Dynamic Text3, but I will not know the specific text in advance. This is simply possible by running in a loop but, is there any way to do this without using each?
Update:
$('td').filter(function(){
return !!$.trim($(this).text());
}).last().css('color', 'red');
Demo: Fiddle
This should work now
var td = $('table td:last');
function findTD() {
if (!td.text().replace(/\u00a0/g, "").length) {
if (td.parent().is(':not(:first)')) {
td = td.parent().prev().find('td');
return findTD();
} else {
return 'No text found!';
}
} else {
return td.text();
}
}
alert(findTD());
FIDDLE
UPDATE This doesn't cover OP needs, mis understood OP's question
Use :contains selector :
http://jsfiddle.net/NkYZf/2
var search = "Dynamic Text3";
$('table td:contains("'+search +'"):last').css('color','red');
You can use :contains
var lastTd = $('td:contains("' + text + '"):last');
Here is a possible POJS solution
HTML
<table>
<tr>
<td>Dynamic Text1</td>
</tr>
<tr>
<td> </td>
</tr>
<tr>
<td>Dynamic Text2</td>
</tr>
<tr>
<td>Dynamic Text3</td>
</tr>
<tr>
<td> </td>
</tr>
</table>
Javascript
var treeWalker = document.createTreeWalker(document.body, NodeFilter.SHOW_ELEMENT, function (node) {
if (node.tagName === "TD" && node.textContent.trim()) {
return NodeFilter.FILTER_ACCEPT;
}
return NodeFilter.FILTER_SKIP;
}, false);
while (treeWalker.nextNode()) {}
console.log(treeWalker.currentNode !== document.body ? treeWalker.currentNode : null);
On jsfiddle
$("td").filter(function() { return $.text([this]) == 'Dynamic Text3'; })
.addClass("red");
How do I get the index of the <tr> in the table but only if it has <td>s and not <th>s
If I use a click event below it will alert the index of the with td and th but I only want <tr> with <td>s
thanks
$('td').click(function(){
var s = $(this).parents('table tr:has(td)').index();////// returns
alert(s);
});
<table>
<tr>
<th><th><th><th><th><th><th><th><th><th>
</tr>
<tr>
<td><td><td><td><td><td><td><td><td><td>
</tr>
<tr>
<td><td><td><td><td><td><td><td><td><td>
</tr>
<tr>
<td><td><td><td><td><td><td><td><td><td>
</tr>
<tr>
<td><td><td><td><td><td><td><td><td><td>
</tr>
</table>
Try this...
$('td').click(function(){
if ( ! $(this).closest('table').find('th').length ) {
var s = $(this).closest('tr').index();
alert(parseInt(s) + 1);
}
});
JS FIDDLE LINK
Your given code is working properly. see this jsfiddle.
I am new to HTML and JavaScript. I got a problem like this in HTML (This code below only visualize the problem for you to easy to reference.)
<tr>
<td>1</td>
<td>Harry</td>
</tr>
<tr>
<td>2</td>
<td>Simon</td>
</tr>
<td>3</td>
<td>Maria</td>
</tr>
</tr>
<td>4</td>
<td>Victory</td>
</tr>
This is a name list, however the problem is that sometime i need to add more name into this table and I HAVE TO ADD in front of Number 1, so meaning i have to re-write the number list, (EX: 1 1 2 3 4 --> 1 2 3 4 5). I feel that is not a good way.
NOTE: I don't want to change the list number decrease from top to bottom. And this is a HTML file so can't apply PHP
Anyone can help me to make the number to a variable like "i" and a function can help me to fill variable i increment from top to bottom automatically like
<tr>
<td>i</td>
<td>Harry</td>
</tr>
<tr>
<td>i</td>
<td>Simon</td>
</tr>
<td>i</td>
<td>Maria</td>
</tr>
</tr>
<td>i</td>
<td>Victory</td>
</tr>
Function Fill_i for example:
I think that JavaScript should be used in this case. Thanks for your help and suggestion on this problem.
Again: I am not allowed to use PHP or ASP and when I add a new name, I add it manually by HTML.
You can use a css counter - MDN
table {
counter-reset: section;
}
.count:before {
counter-increment: section;
content: counter(section);
}
<table>
<tr>
<td class="count"></td>
<td>Harry</td>
</tr>
<tr>
<td class="count"></td>
<td>Simon</td>
</tr>
<tr>
<td class="count"></td>
<td>Maria</td>
</tr>
<tr>
<td class="count"></td>
<td>Victory</td>
</tr>
</table>
FIDDLE
This should work for you:
<table>
<tr>
<td>Harry</td>
</tr>
<tr>
<td>Simon</td>
</tr>
<tr>
<td>Maria</td>
</tr>
<tr>
<td>Victory</td>
</tr>
</table>
<script>
var tables = document.getElementsByTagName('table');
var table = tables[tables.length - 1];
var rows = table.rows;
for(var i = 0, td; i < rows.length; i++){
td = document.createElement('td');
td.appendChild(document.createTextNode(i + 1));
rows[i].insertBefore(td, rows[i].firstChild);
}
</script>
The script should be placed immediately after your table. It goes through each row of your table and adds an extra cell to the beginning with the incrementing number inside that cell.
JSFiddle Demo
Edit: seems like the other solution posted would work do (was added while I typed this up).
You really should be using PHP to do something dynamic like this, which would become trivial with a single for loop.
However, if you insist on using HTML/Javascript (or perhaps this is a 'static page'...) then what you are asking should be possible.
You could add a class to each of the <td> elements you want to use, so:
<tr>
<td class='personid'>i</td>
<td>Harry</td>
</tr>
<tr>
<td class='personid'>i</td>
<td>Simon</td>
</tr>
<td class='personid'>i</td>
<td>Maria</td>
</tr>
</tr>
<td class='personid'>i</td>
<td>Victory</td>
</tr>
Then you would have a javascript function that does something like this:
var list = document.getElementsByClassName("personid");
for (var i = 1; i <= list.length; i++) {
list[i].innerHTML = i;
}
Are you sure you don't want an ordered list?
<ol>
<li>Fred</li>
<li>Barry</li>
</ol>
<script>
function addRow(index, name){
var tbody = document.getElementById("nameList");
var row = document.createElement("tr");
var data1 = document.createElement("td");
data1.appendChild(document.createTextNode(index));
var data2 = document.createElement("td");
data2.appendChild(document.createTextNode(name));
row.appendChild(data1);
row.appendChild(data2);
tbody.appendChild(row);
}
var name=new Array();
name[0]="Harry";
name[1]="Simon";
name[2]="Maria";
name[3]="Victory";
for(var i=0; i < name.length; i++) {
addRow(i,name[i]);
}
</script>
<html>
<body>
<table id="nameList">
</table>
</body>
</html>
I would say do this (im going to assume you are not going to load in jquery or anything fancy):
<html>
<head>
<script type="text/javascript>
function writeTable(){
// list of names
var myList = [ "name1", "name2", "etc", "etc"];
// your variable to write your output
var outputTable = "<table>";
//the div to write the output to
var outputDiv = document.getElementById("output");
//the loop that writes the table
for (var i=0; i<myList.length; i++){
outputTable += "</tr><td>"+i+"</td><td>"+myList[i]+"</td></tr>";
}
//close the table
outputTable += "</table>";
//write the table
outputDiv.innerHTML = outputTable;
}
</script>
</head>
<body onload=writeTable()>
<div id='output'></div>
</body>
</html>
hope this helps :)
Try this
$(document).ready(function() {
var addSerialNumber = function () {
$('table tr').each(function(index) {
$(this).find('td:nth-child(1)').html(index);
});
};
addSerialNumber();
});
