I have large form mainly drop down lists and checkboxes. Checkboxes are created dynamically so i don't know their id's before they are created. I use drop down onChange event to do create them on the fly.
How can i loop trough the form and get all the checkboxes that are checked, that is their id and their value? I need to do this only for check boxes that are checked. All checkboxes share the same name, that is: categoriesfilters[]. Currently i have on click event on the checkbox which invoke the javascript function.
Here is the code:
function update_number_of_adds_found(field_dropdown,selected_value) {
selected_value="";
var addtypeid = $("#addtypeid").val();
// trying to store the values of the checkboxes
$(this).find("input[type=checkbox]:checked").each(
function() {
var id = $(this).attr('id');
var value = $(this).val(); // or maybe attr('value');
// the data is stored, do whatever you want with it.
alert(value);
}
);
var selected_value = {
addtypeid: addtypeid,
// need to add the ids and the values here as well
};
var url = "<?php echo site_url('search/findNumberOfAdds'); ?>";
$.post(url, selected_value, function(r){
if(r) {
$('#totalNumOfAdds').empty();
$("#totalNumOfAdds").append(r.result);
} else {
// alert(selected_value);
}
}, 'json')
}
Regards, John
Try this :
var categories = [];
$("input[name='categoriesfilters[]']:checked").each(
function() {
var id = $(this).attr("id");
var value = $(this).val();
categories[categories.length] = {id : value};
}
);
console.log(categories);
$.post(url, categories, function(r){
...
Try this :
$('form').submit(function(){
$(this).find("input[type=checkbox]:checked").each(
function() {
var id = $(this).attr('id');
var value = $(this).val(); // or maybe attr('value');
// the data is stored, do whatever you want with it.
}
);
});
I guess you want to check that on form submit.
var arr = [];
$('input[name^="categoriesfilters"]:checked').each(function() {
var obj = {
id: $(this).attr('id');
value: $(this).val();
};
arr.push(obj);
});
console.log(arr); // show us the array of objects
Would you like to use Jquery?
Add a class to each of the checkbox i.e "class_chk";
$(function(){
$('.class_chk').each(function(){
if($(this).is(':checked')){
var id = $(this).attr('id');
var val = $(this).val();
alert("id = "+id+"---- value ="+val);
}
});
});
The above way you can get all the check box id and value those are checked.
Thanks..

I want to catch the argument whose checkbox is checked but if my tr is under form then he is giving me the whole tr. Please help me.
Here is my jQuery code:
$('#form').on('submit',function(e){
e.preventDefault();
if($('.checkbox').is(':checked')){
var selector = $(this).closest("tr")//get closest tr
console.log(selector)
//get select valus
var id = selector.attr('data-id');
alert(id);
var package_name = selector.find('.visa_type').val();
var prcs_type_price = selector.find("select[name=processing_type]").val();
var processing_type = selector.find("select[name=processing_type] option:selected").text();
var total = selector.find(".package_price").text(prcs_type_price).val()
var date = selector.find('.travel_date').val();
}
)};
Just run .each over the checked ones
$('#form').on('submit', function(e) {
e.preventDefault();
$('.checkbox:checked',this).each(function() {
const $row = $(this).closest("tr");
const id = $row.id;
const package_name = $row.find('.visa_type').val();
})
You CAN do this .on("input" and have the fields update on any change
I want to store the multiple id to hidden field.
So value able to bind to controller.
<form:hidden id="ids" path="ids" value="${ids }"/>
When click button delete will call jquery to delete row.
var deleteIds = [];
$("#deleteRow").on('click', function() {
deleteIds = $('.case:checkbox:checked').val();
$('.case:checkbox:checked').parents("tr").remove();
$('#ids').val(deleteIds);
});
My question is
How to set the value into ids?
Thank You.
The tag from doesn't have the attribute value. You can check the attributes for the form tag here.
However, you can use jQuery to modify custom attributes. Here's a working fiddle:
var deleteIds = [];
deleteIds = ["1","2","3","4"];
$('#ids').attr("value",deleteIds);
alert($('#ids').attr("value"));
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form id="ids" path="ids" value="${ids }"/>
By creating multiple <form:hidden/>, you can get what you want. I assume you when you click #deleteRow, table rows is deleted and you submit form of these ids to server, so we can make it by follow.
Cause I even don't know your html structure, so I've just tried to modify your script, may help you;)
var deleteIds = [];
$("#deleteRow").on('click', function() {
$('#ids').remove();
deleteIds = $('.case:checkbox:checked').val();
$('.case:checkbox:checked').parents("tr").remove();
for (var i = 0; i < deleteIds.length; i++) {
// formId should be replaced to your form id
$('#formId').append('<form:hidden id="ids" path="ids" value="' + deleteIds[i] +'"/>');
}
// $('#formId').submit(); comment this line, cause there is another button to submit form.
});
I able to set the multiples value to hidden field. Answer as below.
<form:hidden id="ids" path="ids" value="${ids }"/>
$("#deleteRow").on('click', function() {
var deleteIds = [];
$('.case:checkbox:checked').each(function(i){
if($('#ids').val() != ''){
deleteIds[i] = $('#ids').val() + "," + $(this).val();
}else{
deleteIds[i] = $(this).val();
}
});
$('#ids').attr("value",deleteIds);
});
The each(function(i)) will loop all the checkbox and store in array[], after that assign the array to hidden field.
Here is my jQuery, I have it working properly but once my row is added the user input in the inputs are still there and not cleared. How do I fix this?
// Removing menu rows
$('.menu-items').on('click', '.delete', function(){
$(this).closest('.menu-row').remove();
});
// HTML
var MENU_ROW_TEMPLATE = '<div class="menu-row"><span class="item-description">$description</span><div class="control-items"><span class="item-price">$price</span><span class="delete">X</span></div></div>'
// Adding menu rows
$('.menu-category').on('click', 'button', function(){
var $row = $(this).closest('.add-item');
var name = $row.find('input').first().val();
var price = $row.find('input').last().val();
var newRowHtml = MENU_ROW_TEMPLATE.replace('$description', name).replace('$price', price);
var $newRow = $(newRowHtml);
var $lastMenuRow = $row.closest('.menu-category').find('.menu-row').last();
$newRow.insertAfter($lastMenuRow);
});
Sorry for my poor explaining skills.
Clear the name and price after you get the values...
...
var name = $row.find('input').first().val();
var price = $row.find('input').last().val();
$row.find('input').first().val('');
$row.find('input').last().val('');
...
I'm attempting to iterate through an object.key (newPickup) and set the value of object.key equal to the value specified in a form. I can get through to the end without throwing any errors however, when i call the object all items are undefined. I set up a fiddle with it already loaded and I'm hoping one of you talented magnificos can let me know where I messed up. Thanks in advance.
Fiddle: http://jsfiddle.net/kevinmota/X7MW6/
<button id="startPickup">Schedule Pickup</button>
<div id="pickupWrap"></div>
function Pickup(pickupDate, clinicName, phoneNumber, qtySpec, fedexConfirm){
this.pickupDate = pickupDate;
this.clinicName = clinicName;
this.phoneNumber = phoneNumber;
this.qtySpec = qtySpec;
this.fedexConfirm=fedexConfirm;
}
//The Pickup Object
var newPickup = new Pickup();
//Click the button to make the form
$("#startPickup").click(function(){
//Empty if exists
$("#pickupWrap").empty();
//Make the inputs
$.each(newPickup, function(key,value){
$('#pickupWrap').append("<label for=\""+key+"\">"+key+": </label><input type=\"text\" id=\""+key+"\" class=\"pickupInput\"><br>");
});
//Make the button
$('#pickupWrap').append("<button id='submitPickup'>Submit Pickup</button");
//Capture the form inputs from pickup
$("#submitPickup").click(function(){
console.log("click");
//Get Values and Indexes
$('.pickupInput').each(function(){
var pickupIndex = $(this).attr("id");
var pickupValue =$(this).val();
console.log(pickupIndex+" | "+ pickupValue);
//Set newPickup to appropriate value
$.each(newPickup, function(key, value){
if (key === pickupIndex) {
console.log("we have a match");
value = pickupValue;
};
})
});
console.log(newPickup);
});
});
value = pickupValue isn't what you want, you need to specify the object[key] and set that:
$.each(newPickup, function(key, value){
if (key === pickupIndex) {
console.log("we have a match");
newPickup[key] = pickupValue;
};
})
I have a list of checkboxes. Upon clicking on each of the checkboxes i am adding the value to the hidden variable. But the question is if I want to remove the value from the list upon unchecking the checkbox . How this piece cab be done
here is the hidden form variable
<input name="IDList[]" type="hidden" id="IDList" value="" />
and the jquery
$(".myCheckboxClass").change(function() {
var output = 0;
$(".myCheckboxClass").change(function() {
if ($(this).is(":checked")) {
output += ", " + $(this).val();
} else {
output = $.grep(output, function(value) {
return value != $(this).val();
});
}
$("#IDList").val(output);
});
});
Something like this: (demo) http://jsfiddle.net/wesbos/5N2kb/1/
we use an object called vals to store the info. ADding and removing as we check/uncheck.
var vals = {};
$('input[type=checkbox]').click(function() {
var that = $(this);
if (that.is(':checked')) {
console.log(this.name);
vals[this.name] = "In your Object";
}
else {
delete vals[this.name];
}
console.log(vals);
});
Following your logic, you could do this:
$('#IDList').data('value', []);
$(".myCheckboxClass").change(function() {
var list = $('#IDList').data('value');
if ($(this).is(":checked")) {
list.push($(this).val());
} else {
var indexToRemove = list.indexOf($(this).val());
list.splice(indexToRemove, 1);
}
$('#IDList').val(list);
});
But if you only care about the value of #IDList upon data submission or other actions, you probably want to consider an alternative approach: collating the checked values when you need them.
$('#form').submit(function() {
var list = $('input.myCheckboxClass:checked', this).map(function() {
return $(this).val();
}).get();
$('#IDList').val(list);
});
See both of the above in action: http://jsfiddle.net/william/F6gVg/1/.
