I want to append rows to the table one by one, not all at once. Problem i'm facing is, no. of rows is very large, say 10,000. It append all the rows at once after loop terminates. I want it to work like, with each iteration, it should append the row to the table.
$(document).ready(function(){
for(var i=0;i<1000;i++){
var name = "name "+i;
var email = "email"+i+"#vvv.com";
var markup = "<tr><td><input type='checkbox' name='record'></td><td>" + name + "</td><td>" + email + "</td></tr>";
//$("table tbody").append(markup);
//$("tbody").parent("table").append(markup);
$("tbody").after(markup);
}
});
table{
width: 100%;
margin-bottom: 20px;
border-collapse: collapse;
}
table, th, td{
border: 1px solid #cdcdcd;
}
table th, table td{
padding: 10px;
text-align: left;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<table>
<thead>
<tr>
<th>Select</th>
<th>Name</th>
<th>Email</th>
</tr>
</thead>
<tbody>
<tr>
<td><input type="checkbox" name="record"></td>
<td>Name</td>
<td>email#vvv.com</td>
</tr>
</tbody>
</table>
I see what you are trying to do. You may try to use setTimeout to achieve this. You are trying to loop an array but in your code you are just generating new rows. So I tried to implement your code into this solution. If you are trying to loop an array you need to modify this.
$(document).ready(function(){
appendOneByOne(1000)
});
function appendOneByOne(i){
if(i !== 0){
setTimeout(function(){
var name = "name "+i;
var email = "email"+i+"#vvv.com";
var markup = "<tr><td><input type='checkbox' name='record'></td><td>" + name + "</td><td>" + email + "</td></tr>";
$("tbody").after(markup);
appendOneByOne(--i)
});
}
}
You can also use window.requestAnimationFrame(); but take care for cross-browser issues.

I have a table that is filled dynamically with a csv file. I created a table that inside itself has dropdowns in some columns.
What I want to do now is to check if a value exists in the cell where the dropdown is supposed to be, if so to check if it exists in the dropdownlist if yes then set this as selected in dropdown list otherwise selected is at default value and the cell gets red margine around.
Here is a jsFiddle with an example as how my code currently looks like:

option += '<option value="'+ firstshortcut[i] + '">' + firstDDM[i] + '</option>';
}
select = '<select class="firstDDM" type="firstDDM">' + option + '</select>';
$("tr").each(function() {
$(this).find("td:eq(3)").append(select);

You can edit the select text you are entering. Following are the things which I think you want to achieve:
Identify if the dropdown has a certain value and preselect them if possible.
If the dropdown does not have correct value for pre selection then mark them as error field.
If the above mentioned points are incorrect please let me know i will make the relevant changes which are required.
I have added a condition check if (firstshortcut[i] == $(this).find("td:eq(3)")[0].innerHTML) you can replace it with any condition that you want.
Replace the following jquery snippets
$("tr").each(function () {
var option = "",
select = "",
classObject = '',
isSelected = false;
if($(this).find("td:eq(3)")[0]){
for (var i = 0; i < firstDDM.length; i++) {
if (firstshortcut[i] == $(this).find("td:eq(3)")[0].innerHTML) {
option += '<option selected="selected" value="' + firstshortcut[i] + '">' + firstDDM[i] + '</option>';
isSelected = true;
}
else
option += '<option value="' + firstshortcut[i] + '">' + firstDDM[i] + '</option>';
}
classObject = !isSelected ? 'errorDropDown' : '';
select = '<select class="firstDDM' + ' ' + classObject + '" type="firstDDM">' + option + '</select>'
$(this).find("td:eq(3)").append(select);
}
});
Add this class to the css file:
.errorDropDown {border: 1px solid red;}

you have multiple options
1-use pagination like 1,2,3,4,etc
->this can be done using js and php or php with sql setting limit on your query and shift it when you choose another page
2-lazy loading on scroll -> this can be done using js
example using php with my sql

I am using table search functionality using this code -
https://www.w3schools.com/howto/tryit.asp?filename=tryhow_js_filter_table.
When user search for any row data using some search characters like "Jac", I want to change the color of these 3 characters only and want to show entire row. How can I change the color of these 3 characters? Or search input characters?
EDIT - My code is:
$("#searchBox").keyup(function() {
var input, filter, table, tr, td, i;
input = document.getElementById("searchBox");
filter = input.value.toUpperCase();
if (filter.length > 1) {
table = document.getElementById("myTable");
tr = table.getElementsByTagName("tr");
for (i = 0; i < tr.length; i++) {
td = tr[i].getElementsByTagName("td")[1];
if (td) {
if (td.innerHTML.toUpperCase().indexOf(filter) > -1) {
var regx = new RegExp(filter, "g");
var newstring = td.innerHTML.replace(regx, '<span class="highlight">' + filter + '</span>');
td.innerHTML = newstring;
tr[i].style.display = "";
} else {
tr[i].style.display = "none";
}
}
}
} else {
table = document.getElementById("myTable");
tr = table.getElementsByTagName("tr");
for (i = 0; i < tr.length; i++) {
tr[i].style.display = "";
}
}
});
Output of above code is not correct. It will work only when length of search string is more than 1. If I enter 3 characters it failed.
Might be an overkill approach. But this how I got it working.
The technique:
1- Get the original table (as a whole DOM) into a JS variable
2- Clone that variable into another JS variable.
3- The clone is used as a reference. Will remain intact never be modified.
4- The highlight works by extracting the found phrase, wrap with a <span> having that span is given a certain CSS to stand out from the rest of the text.
The reason behind this is that, if we edit the original table, and then we try to search again, the HTML tag that got inserted will be included in the searched terms and therefore, the search will break down.
We will be searching the clone always, then will get the text from the clone, process it, and then apply the new processed phrase to the original table. In other words, If the searched phrase is found in the clone object, its content will be copied over to the original table.
If I were to do this again, I would replace the whole thing with JQuery. But anyhow, this code needs to be optimized.
var originalTable = document.getElementById("myTable");
var realTr = originalTable.getElementsByTagName("tr");
var cloneTable = originalTable.cloneNode(true);
var cloneTr = cloneTable.getElementsByTagName("tr");
function myFunction() {
var input, filter, cloneTd, cloneTdValue, realTd, i, inputValue, inputValueUpper;
input = document.getElementById("myInput");
inputValue = input.value;
inputValueUpper = inputValue.toUpperCase();
for (i = 0; i < cloneTr.length; i++) {
cloneTd = cloneTr[i].getElementsByTagName("td")[0];
if (cloneTd) {
var cloneTdValue = cloneTd.innerHTML;
var cloneTdValueUpper = cloneTdValue.toUpperCase();
var index = cloneTdValueUpper.indexOf(inputValueUpper);
if (index > -1) {
var newStr = wrapStuff(inputValue, cloneTdValue, index);
realTr[i].style.display = "";
realTd = realTr[i].getElementsByTagName("td")[0];
realTd.innerHTML = newStr;
} else {
realTr[i].style.display = "none";
}
}
}
}
function wrapStuff(input, tdStr, index) {
if (input.length === 0)
{
return tdStr;
}
var before, after, searched, extractLen, extractedVal, newString;
extractLen = index + input.length;
before = tdStr.substring(0, index);
after = tdStr.substring(extractLen, tdStr.length);
var newIndex = after.indexOf(input);
//Recursive function: yeah, my head got spinning.
//this is to apply the same code to the second half of the spliced string, because indexOf will only find the first occurance.
if (newIndex > -1) {
after = wrapStuff(input, after, newIndex);
}
extractedVal = tdStr.substring(index, extractLen);
newString = before + "<span class=\"highlight\">" + extractedVal + "</span>" + after;
return newString;

Capture the search phrase (the word you are searching or looking for). Capture the search area (the table or paragraph you are searching into). Look into the search area to see if you can find the search phrase. Once it exists, replace with a string that has an HTML element tag surrounding it.
Replace the searched word with the same word but wrapped in a span that has certain CSS class. Use CSS to customize the look.
var toLookInto = $("#toLookInto").html();
$("#toFind").on("keyup", function() {
var toFind = $("#toFind").val();
var regx = new RegExp(toFind, "g");
var newstring = toLookInto.replace(regx, '<span class="highlight">' + toFind + '</span>')
$("#toLookInto").html(newstring)
});
.highlight {
color: red;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.0.0/jquery.min.js"></script>
<p id="toLookInto">
dummy text foo bar cat mewo dummy text foo bar cat mewo dummy text foo something odd bar cat mewo dummy text foo bar cat mewo
</p>
<br>
<input type "text" id="toFind" />
<lable>The text field will be triggered on every key pressed</label>
The code basically edit a table cell.
I want to use the not() method so that everytime I click outside the temporary input created I replace it with a table cell. I guess the code run in a block and doesn't detect any input with an id of "replace" so how can I fix that ?
Also I want to store the element (th or td) that fire the first event(dblclick) so that I can use it to replace the input with the right type of cell but it seems to only stores the element that first triggers the event and I don't really understand why.
Full code here
$(function () {
$(document).on("dblclick", "th, td", function (event) {
var cellText = $(this).text();
$(this).replaceWith("<input type='text' id='replace' value='" + cellText + "'>");
var $typeCell = $(event.currentTarget); // Store element which trigger the event
$("body").not("#replace").on("click", function () { // .not() method
cellText = $("#replace").val();
if ($typeCell.is("th")) {
$("#replace").replaceWith("<th scope='col'>" + cellText + "</th>");
}
else {
$("#replace").replaceWith("<td>" + cellText + "</td>");
}
});
});
});
I have modified HTML and JavaScript to avoid any possible errors. The correct practice is to wrap all th's in a thead and all td's in tbody.
$(document).on("dblclick", "th, td", function(event) {
var cellText = $(this).text();
$(this).replaceWith("<input type='text' id='replace' value='" + cellText + "'>");
});
$("body").on("click", function() {
if (event.target.id != 'replace' && $('#replace').length != 0) {
var cellText = $("#replace").val();
if ($('#replace').parents().is('thead'))
$("#replace").replaceWith("<th scope='col'>" + cellText + "</th>");
else
$("#replace").replaceWith("<td>" + cellText + "</td>");
}

Why my css display irregular?
Any solution to solve my problem?
Thank you very much
The short answer is that you can not build a table in that way.
Your first snippet of code appends the table headers. Then DOM automatically adds closing table tag.
Your next snippet of code runs a loop to append rows. However, the table was already created in the previous step.
So you end up with 2 tables in the DOM which don't align.
Suggest building the table as a string and then appending that string to the div so that the DOM builds a single table.
UPDATE:
This code, in response to OP comment, demonstrates how to make the original code work with just 3 very minor changes. The table is first built as a string. The string is then appended to the innerHTML of the container. Doing it this way prevents the DOM from prematurely adding a closing tag to the table element, as was the case in the original code.
And now the table header and rows align, which was the stated problem.
Click the "Run code snippet" button to see it work.
function success() {
var html =('<table class="table">\
<tbody>\
<tr>\
<th>Status</th>\
<th>Room Grade</th>\
<th>Meal</th>\
<th>Per Room.Night</th>\
<th>Cancel Policy</th>\
<th>Book It</th>\
</tr>')
for(var i=0; i<10; i++){
html += ('<tr>\
<td>' + Status + '</td>\
<td>' + RmGrade + '</td>\
<td>' + Meal + '</td>\
<td>' + Currency + ' ' + TotalRate + '</td>\
<td>Cancel Policy</td>\
<td>\
<form action="details.html">\
<button class="bookbtn mt1" type="submit">Book</button>\
</form>\
</td>\
</tr>');
}
html += ('</tbody>\
</table>');
$('#container').html( html );
}
// test data
var Status="OK", RmGrade=5, Meal="Yes", Currency="Euro", TotalRate="100";
success();
td,th {padding:2px; border:1px gray solid;}
th {background-color: peru; }
table {border-collapse: collapse;}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.0/jquery.min.js"></script>
<div id="container"></div>
Do you mean that the table content is not aligned properly? Verify your CSS that there is no width property on your TD element.
HTML:
<table>
<tr>
<th>Test1</th>
<th>Test2</th>
<th>Test3</th>
</tr>
<tr>
<td>Wat</td>
<td>Wat2</td>
<td>Wat3</td>
</tr>
<tr>
<td>Foo</td>
<td>Foo2</td>
<td>Foo3</td>
</tr>
</table>
CSS:
table {
width: 100%;
}
th, td {
text-align: left;
}
