on click of the add button I want to remove the textbox but its contents should get displayed say inside a div. i.e. I want to stop user from modifying this but disabling the textbox is not an option. How do I achieve this ?
Basically what you need to do is to do the replacement as soon as you click on the add link. The replacement is really simple.
// Do the magic here (Kuroir)
$(this).parent().parent().find('input').each(function(){
$(this).replaceWith('<div class="inactive">' + $(this).val() + '</div>');
});
Basically, you're going back to the tr level, then finding the input and doing the replacement for that row.
Working Solution: http://jsfiddle.net/kuroir/SXppg/
To get content from an <input> and place it in a <div>, you want something like:
$('#target-div-id').text(
$('#Col0').val()
);
I'm reasonably sure that's what you're trying to do.

In above HTML code, when button is clicked, I have to increment the two text box values
For example, click a button, price text box value will be 3000, discount text box value will be 550
price text box value is incremented, but discount value will not be changed.
Second script are run,but the text box value are not changed.
You just forget to change the value of the discount input.
<script type="text/javascript">//second script
function buttonClick() {
//alert("hi");
var n = document.getElementById('rs').value;
alert(n);
var i = 50;
if (i == 50) {
alert(i);
var n = +n + +i;
alert(n);
$("#rs").val(n) // add this line
}
}
</script>
You have not written anything to change value of discount textbox.
you can do as follows:
$('.qtyplus').click(function (e) {
e.preventDefault();
qty = $('.qty').val();
discount = $('#rs').val();
var currentQtyVal = parseInt(qty);
if (!isNaN(currentQtyVal)) {
$('input[name=quantity]').val(currentQtyVal + 1000);
} else {
$('input[name=quantity]').val(1000);
}
var currentDiscountVal = parseInt(discount);
if (!isNaN(currentDiscountVal)) {
$('input[name=rs]').val(currentDiscountVal + 50);
} else {
$('input[name=rs]').val(50);
}
});
I have a basic task list with due dates. The CSS script for showing overdue dates works. If I add new entries via the from input the css is not applied to overdue items.

I did a jsfiddle that gets you partially there. There's still an issue when you load, but that should get you going:
$(document).ready(function(){
$(".add-row").on('click',function(){
var task = $("#task").val();
var date = $("#date").val();
var markup = "<tr><td>" + task + "</td><td>" + date + "</td></tr>";
$('table tbody').append(markup);
checkDate();
});
function checkDate() {
$('table td').each(function() {
var row_date = Date.parse($(this).text().replace(/(\d{2})\/(\d{2})\/(\d{4})/, '$2/$1/$3'));
var now_date = new Date().getTime();
if(row_date < now_date) {
$(this).closest('tr').addClass('past');
}
});
}
});

Stackoverflow snippet - using javascript onclick function remove current row is working fine.
function removeRow(onclickTAG) {
// Iterate till we find TR tag.
while ( (onclickTAG = onclickTAG.parentElement) && onclickTAG.tagName != 'TR' );
onclickTAG.parentElement.removeChild(onclickTAG);
}
as part of jsfiddle - test and plane html file the code is not working at-least with javascript.
Unable to delete|call delete row function. while deleting row remove the price from the Added Total.
I should only allow number for the input tag, but it is working only for the first row input element. Input type must be text only. type number allows these like {.+-}
Iam unable to solve it as new to jquery and its xpath element navigation.
There are two issues with your code:
$('table#productTable:.remove-row').on('click', function () {
here :. is an syntax error, and it is showing in console.
Second to put an event listener on dynamic html, you have to use $(document).on() like:
$(document).on('click', '.remove-row', function(){
Check the updated working fiddle
here
I have added events using on click event handler as elements get added dynamically.
Have updated both events:
1. Event for remove button
$('table#productTable').on('click', '.remove-row', function() {
//$("#productTable").each(function () {
// added total minus deleting element price.
$(this).closest('tr').remove(); // https://stackoverflow.com/a/11553788/5081877
//$(element).parent().remove();
//});
});
2. Event for input tag
$('table#productTable').on('input propertychange',' > tbody > tr > td:nth-child(3) > input', function() {
$.each($('input[type=text]'), function() {
this.value = this.value.replace(/[^0-9]/g, '');
});
});
Refer this fiddle
Please change $('.row).onclick like this
$('table#productTable').on('click', '.remove-row', function()
And remove this $("#productTable").each(function () {

Because you are adding extra quotes in beginning and end in variable k. use:
var k = 'refNm_error' + (i+1);
You might need to reload the DOM after adding dynamic elements.
This link might help
Update, when you created your dynamic table rows for the table you didn't assign unique ids for input elements. So I updated the addRow handler:
$(document).on("click", ".addRowAux", function () {
to add unique input ids, like following:
$("#aux").append('<tr><td align="center">' + countrow + '</td><td align="center"><input type="text" name="ref_name[]" id="ref_name_' + countrow + '"/><span id="refNm_error_' + countrow + '">Please fill</span>...
and also I changed in the code:
<span id="removeRowaux">Remove</span>
to use class instead of an id:
<span class="removeRowaux">Remove</span>
Now the remove row handler listens to events from spans with class removeRowaux:
$(document).on('click', '.removeRowaux', function ()
Now the remove row functionality works and there are no spans with identical ids. So I don't think there was anything wrong with getElementById() in the code - it works fine :-)
