Rows (id='row_property_'+number) in table contain four columns :
select element (id='multiple_object_type_'+number)
input type="text" (id='multiple_instance_id_'+number)
nested table (id='table_properties_'+number)
input type="button"
How to iterate through each row and collect data in two arrays from select and input with jquery ?
Ok, add classes to the select and input elements so that the table looks something like this:
<table id="myTable">
<tr>
<td><select class="rowSelect"></select></td>
<td><input type="text" class="rowInput" /></td>
... etc ...
</tr>
</table>
Then you can get the values from each row like this in jquery:
$(function(){
$('#myTable tr').each(function(){
alert('select value is '+$(this).find('select.rowSelect'));
alert('input value is '+$(this).find('input.rowInput'));
});
});
var selectArray = $('table tr td > select').map(function() {
return $(this).val();
}).get();
var inputArray = $('table tr td > input:text').map(function() {
return $(this).val();
}).get();
This might do what you want.

I am able to perform calculations on this row. However, when I dynamically add rows with jquery, calculations are not working on the other rows.
When the calculating function is bind a button onclick, everything works well. But not on input keyup as required. I want to perform calculations on the new added row with onkeyup on qty and price input fields.
Note than upon cloning, the ids are stripped of the current row and assigned to the new row for reference.
You probably not registering keyup function when you adding new row.
You should do :
$('#dailysale_qty, #dailysale_price').unbind('keyup').keyup( function(...
Every time you adding new row.
#Nosyara The suggested line of code isn't working. Here is how am adding new rows. The commented line is what you suggested.
$(function(){
$('#newitembtn').click(function(){
//$('#dailysale_qty, #dailysale_price').unbind('keyup').keyup(function() {
var last_row = $('#dailysale_tbody').find('tr:last');
var newrow = last_row.clone();
last_row.find('#items_select').removeAttr('id');
last_row.find('#brands_select').removeAttr('id');
last_row.find('#models_select').removeAttr('id');
last_row.find('#dailysale_qty').removeAttr('id');
last_row.find('#dailysale_price').removeAttr('id');
last_row.find('#dailysale_total').removeAttr('id');
newrow.find('#items_select').val('');
newrow.find('#brands_select').val('');
newrow.find('#models_select').val('');
newrow.find('#dailysale_qty').val('');
newrow.find('#dailysale_price').val('');
newrow.find('#dailysale_total').val('');
last_row.after(newrow);
});
});
});
imagine i have 3 rows in a table, there is 3 input fields in every row. when i type something in the last input field it should add new row following that last row also when i hit backspace and all fields in latest row is empty then the new added row should be remove
i have no idea how to prevent another addition if the new row already appended to the table. this is what i've done so far.
$(document).ready(function(){
$("input[name=class_name\\[\\]]:last-child").keyup(function addNewRow(e){
var parent = $(this).closest('tr');
var tr = parent.clone();
if(e.keyCode != 8){
$("#classes tr:last-child").remove();
}else{
$("#classes").append(tr);
}
});
});
how about a check by selecting the last element again, and compare it to this? If it's not the same, then a row has already been added
Do you mean like this:
<table id="classes">
<tr>
<td><input onchange="process()"/></td><td><input onchange="process()"/></td><td><input onchange="process()"/></td>
</tr>
<tr>
<td><input onchange="process()"/></td><td><input onchange="process()"/></td><td><input onchange="process()"/></td>
</tr>
<tr>
<td><input onchange="process()"/></td><td><input onchange="process()"/></td><td><input onchange="process()"/></td>
</tr>
</table>
Javascript:
function process(){
var parent = $("#classes tr:last-child").closest('tr');
var tr = parent.clone();
if($("#classes tr:last-child td:last-child input").val() !== '')
{
$("#classes").append(tr);
}
else if($("#classes tr:last-child td").eq(0).find("input").val() === '' && $("#classes tr:last-child td").eq(1).find("input").val() === '' && $("#classes tr:last-child td").eq(2).find("input").val() === '')
{
$("#classes tr:last-child").remove();
}
}
here is my sample code
<table id="accessListTable">
<tr class="ui-grid groupHead">
<td><input type="checkbox" class="groupHeadCheck"/></td>
</tr>
<tr>
<td><input type="checkbox" id="1"/></td>
</tr>
<tr>
<td><input type="checkbox" id="2"/></td>
</tr>
<tr>
<td><input type="checkbox" id="3"/></td>
</tr>
<tr class="ui-grid groupHead">
<td><input type="checkbox" class="groupHeadCheck"/></td>
</tr>
<tr>
<td><input type="checkbox" id="4"/></td>
</tr>
</table>
E.g, When the checkbox in first row with class groupHeadCheck, all the checkboxex of id 1, 2 and 3 will also be checked.
And if all the checkboxes of 1, 2, and 3 are already checked, the checkbox in first row will be checked.
Please any help!
You can add a click handler to the group checkbox then inside the handler you can find its tr element and the tr's next sibling element till the next occurrence of tr.groupHead
$(function ($) {
$(".groupHeadCheck").on("click", function (event) {
$(this).closest('tr').nextUntil('tr.groupHead').find('input[type="checkbox"]').prop('checked', this.checked)
})
});
Demo: Fiddle
I am sure it can be done in a prettier manner, but this is the basic idea:
$("table tbody").on("change", "input[type=checkbox]", function (e) {
var currentCB = $(this);
var isChecked = this.checked;
if (currentCB.is(".groupHeadCheck")) {
var allCbs = currentCB.closest('tr').nextUntil('tr.groupHead').find('[type="checkbox"]');
allCbs.prop('checked', isChecked);
} else {
var allCbs = currentCB.closest('tr').prevAll("tr.groupHead:first").nextUntil('tr.groupHead').andSelf().find('[type="checkbox"]');
var allSlaves = allCbs.not(".groupHeadCheck");
var master = allCbs.filter(".groupHeadCheck");
var allChecked = isChecked ? allSlaves.filter(":checked").length === allSlaves.length : false;
master.prop("checked", allChecked);
}
});
and if you need to run the code to force the check all state
$(".groupHead").next().find("[type=checkbox]").change();
JSFiddle
This would check all if the first is checked (or uncheck all)
$(document).on('click', '.groupHeadCheck',function() {
$(this).closest('tr').nextUntil('tr.groupHead').find('input[type="checkbox"]').prop('checked', $(this).prop('checked'))
});
you could fiddle a bit with your classes (or IDs) to make it right for you
I know this is already answered, but I wanted a more generic way of doing this. In my case, I wanted to check all in a column until I hit a new group. I also had 3 columns with checkboxes. The ones in the first checkbox column all had names starting with "S_", the second "A_" and the third "C_". I used this to pick out the checkboxes I wanted. I also didn't name the heading checkboxes that were used to do the "check all" so it would stop when it hit the next groupings row.
You could use the class name to apply the same logic.
First, here is what a check all checkbox looked like:
<td>
<input type="checkbox" onchange="checkAll(this, 'S_');" />
</td>
Then the javascript function it calls when clicked:
function checkAll(sender, match)
{
var table = $(sender).closest('table').get(0);
var selector = "input[type='checkbox'][name^='" + match + "']";
for (var i = $(sender).closest('tr').index() + 1; i < table.rows.length; i++)
{
var cb = $(table.rows[i]).find(selector).get(0);
if (cb === undefined)
break;
if ($(cb).is(':enabled'))
cb.checked = sender.checked;
}
}
So it will search each subsequent row for a checkbox with the name starting with "S_". Only the checkboxes the user has rights to will be changed. I was going to use $(td).index() to find the right column, but this didn't work out because some rows had colspan's greater than 1.
so I have some checkboxes, when each one is checked I'm able to get the id number I need from the associated table row and place them into my contacts array.
I also have a Select all checkbox which is meant to grab all the id numbers and stick them into the same array.
Having a bit of trouble trying to figure out the correct syntax to target the tbody, select every table row's data-id, or every table row's input's value.
http://jsfiddle.net/leongaban/7LCjH/
^ In my fiddle example you can see the numbers get added to my array (or the gray div for visualization).
How would you grab all the id numbers from the tbody rows from the Select all checkbox?
jQuery
var contacts = [];
// add multiple select / deselect functionality
$("#selectall").click(function () {
$('.case').attr('checked', this.checked);
//contacts.push($('#tbody').children(tr > td > input).val();)
});
// if all checkbox are selected, check the selectall checkbox
// and viceversa
$(".case").click(function() {
var $tr = $(this).closest("tr");
var id = $tr.data('coworker-id');
contacts.push(id);
$('#arrayContent').empty();
$('#arrayContent').append(contacts+',');
if ($(".case").length == $(".case:checked").length) {
$("#selectall").attr("checked", "checked");
} else {
$("#selectall").removeAttr("checked");
}
});
HTML
<table>
<thead>
<tr>
<td><input type="checkbox" id="selectall"/></td>
<td>Select All</td>
</tr>
<tr>
<td colspan="2"><hr/></td>
</tr>
</thead>
<tbody id="tbody">
<tr data-coworker-id="1">
<td><input type="checkbox" class="case" name="case" value="1"/></td>
<td>1</td>
</tr>
<tr data-coworker-id="2">
<td><input type="checkbox" class="case" name="case" value="2"/></td>
<td>2</td>
</tr>
<tr data-coworker-id="3">
<td><input type="checkbox" class="case" name="case" value="3"/></td>
<td>3</td>
</tr>
</tbody>
You can modify your select all handler like so:
$("#selectall").click(function () {
$('.case').attr('checked', this.checked).each(function() {
contacts.push($(this).val())
});
});
Here is a working example:
var contacts = [];
// add multiple select / deselect functionality
$("#selectall").click(function () {
var els = $('.case')
if (els.first().is(':checked') ) {
els.prop('checked', false);
$('#arrayContent').empty();
} else {
els.attr('checked', true);
$.each(els, function(index, el) {
contacts.push( $(el).val() );
});
$('#arrayContent').empty();
$('#arrayContent').append(contacts.join( ', ' ) );
}
//contacts.push($('#tbody').children(tr > td > input).val();)
});
// if all checkbox are selected, check the selectall checkbox
// and viceversa
$(".case").click(function() {
var $tr = $(this).closest("tr");
var id = $tr.data('coworker-id');
contacts.push(id);
$('#arrayContent').empty();
$('#arrayContent').append(contacts+',');
if ($(".case").length == $(".case:checked").length) {
$("#selectall").attr("checked", "checked");
} else {
$("#selectall").removeAttr("checked");
}
});
and here is fiddle link :: http://jsfiddle.net/kkemple/7LCjH/24/
You can try this
$("#selectall").click(function () {
if($('.case:checked').length == $('.case').length){
//deselect all
$('.case').removeAttr("checked");
contacts = [];
}
else{
//select all
$('.case').attr("checked", "checked").each(function(){
var $tr = $(this).closest("tr");
var id = $tr.data('coworker-id');
contacts.push(id);
})
}
$('#arrayContent').empty();
$('#arrayContent').append(contacts.join(','));
//contacts.push($('#tbody').children(tr > td > input).val();)
});
jsFiddle
Use find instead of children and then loop the elements to add them to the array.
$("#selectall").click(function () {
$('.case').attr('checked', this.checked);
$('tbody').find("input").each(function () {
contacts.push($(this).val()+",");
});
$('#arrayContent').append(contacts);
});
The .find() and .children() methods are similar, except that the latter only travels a single level down the DOM tree.

I know this doesn't quite answer the question using children, but you can use $('#tbody').find('input') to find all the input fields within an element.
i want to iterate through the table rows and get the id and name of each checkbox checked in each tr in the first td and save it in a new Object() called values ex: values.id, values.name
Thanks
<table>
<tr>
<td>
<input id="1" type="checkbox" name="name1" checked="checked">
</td>
<td>
Some input control 1
</td>
</tr>
<tr>
<td>
<input id="2" type="checkbox" name="name2">
</td>
<td>
Some input control 2
</td>
</tr>
</table>
Working example
aRecord is an array of objects with each object containing both the name and ID of each checked checkbox found in the table.
$(document).ready(function() {
var aRecord = [];
$('#your_table input:checkbox:checked').each(function() {
var oChkBox = {};
oChkBox.name = $(this).attr('name');
oChkBox.id = $(this).attr('id');
aRecord.push(oChkBox);
});
var i = aRecord.length;
while (i--) {
alert("Name: "+ aRecord[i].name + " ID: "+ aRecord[i].id);
}
});
http://jsfiddle.net/tracyfu/r6RMV/
var values = {};
$('tr input:checked').each(function(i) {
values[i] = [];
values[i].push($(this).attr('id'));
values[i].push($(this).attr('name'));
});
Will produce:
values = { [1, 'name1'] }
I'm leaving this solution as-is, since you specifically said you wanted to store the values in an object named values, but without knowing what you're going to do with the data, I would store the values in an array instead...
