How to get multiple checkbox value and assign to hidden field - javascript

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.

combobox with array id

I want my combobox and checkbox id contains element of array..
Example: "mySelect$i" or "checkid[i]"..
I want to use this to generate different id.
So, it will be like "mySelect1", "mySelect2" or "checkid1", "checkid2".
Help me please.
Here is my following code:
<script type="text/javascript">
function run(){
var cb = document.getElementById("mySelect");
if(document.getElementById("checkid").checked == true){
cb.disabled = true;
}else{
cb.disabled = false;
}
}
Check Radio Button ID, Name and Value..
It should be unique. otherwise it will treat as all the same.

In Jquery take a different values from single text box id

I am using Data Table in jquery. So i passed one input type text box and passed the single id. This data table will take a multiple text box. i will enter values manually and pass it into the controller. I want to take one or more text box values as an array..
The following image is the exact view of my data table.
I have marked red color in one place. the three text boxes are in same id but different values. how to bind that?
function UpdateAmount() {debugger;
var id = "";
var count = 0;
$("input:checkbox[name=che]:checked").each(function () {
if (count == 0) {
id = $(this).val();
var amount= $('#Amount').val();
}
else {
id += "," + $(this).val();
amount+="," + $(this).val(); // if i give this i am getting the first text box value only.
}
count = count + 1;
});
if (count == 0) {
alert("Please select atleast one record to update");
return false;
}
Really stuck to find out the solution... I want to get the all text box values ?
An Id can only be used once; use a class, then when you reference the class(es), you can loop through them.
<input class="getValues" />
<input class="getValues" />
<input class="getValues" />
Then, reference as ...
$(".getValues")
Loop through as ...
var allValues = [];
var obs = $(".getValues");
for (var i=0,len=obs.length; i<len; i++) {
allValues.push($(obs[i]).val());
}
... and you now have an array of the values.
You could also use the jQuery .each functionality.
var allValues = [];
var obs = $(".getValues");
obs.each(function(index, value) {
allValues.push(value);
}
So, the fundamental rule is that you must not have duplicate IDs. Hence, use classes. So, in your example, replace the IDs of those text boxes with classes, something like:
<input class="amount" type="text" />
Then, try the below code.
function UpdateAmount() {
debugger;
var amount = [];
$("input:checkbox[name=che]:checked").each(function () {
var $row = $(this).closest("tr");
var inputVal = $row.find(".amount").val();
amount.push(inputVal);
});
console.log (amount); // an array of values
console.log (amount.join(", ")); // a comma separated string of values
if (!amount.length) {
alert("Please select atleast one record to update");
return false;
}
}
See if that works and I will then add some details as to what the code does.
First if you have all the textbox in a div then you get all the textbox value using children function like this
function GetTextBoxValueOne() {
$("#divAllTextBox").children("input:text").each(function () {
alert($(this).val());
});
}
Now another way is you can give a class name to those textboxes which value you need and get that control with class name like this,
function GetTextBoxValueTwo() {
$(".text-box").each(function () {
alert($(this).val());
});
}

get all checked checboxes and add their names and values in array

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..

paste input type file value to input type text

i have script like this, for append a new elment based user input
var tmp;
$('#add').click(function(){
var galer=parseInt($('#many').val());
for(var h=1;h<=tmp;h++){
$(".af_"+h).remove();
}
for(var x=1;x<=galer;x++){
$("#kontenPlus").append("<input type='file' id='photo_"+x+"'> <input type='text' id='src_"+x+"'>");
}
tmp=galer;
});
for(var u=1;u<=tmp;u++){
$('#photo_'+u).change(function(){
$('#src_'+x).val($(this).val());
});
}
this html code:
<input type='text' id='many'><div id='add'>Add element</div>
<div id='kontenPlus'></div>
i want to ask why value of '#photo_+x', isn't put in '#src_'+x, is function can be looped ?
LINK:http://jsfiddle.net/rizalfarez/V5AdP/3/
Because these elements are being dynamically created you will need to delegate the event listening like
$(window).on( "change", function() {
//
var id = $(this).id;
//
if (id.indexOf("photo") === 0) {
the reason that the value of text boxes does not get updated is because they are dynamically created, so the change event is not bind to them.
I have changed your code and optimized it a little like this:
var tmp;
$('#add').click(function(){
var galer = parseInt($('#many').val());
$('.af').remove();
for(var x=1;x<=galer;x++)
$('#kontenPlus').append('<div class="af"><input type="file" id="photo_'+x+'"><input type="text" id="src_'+x+'"></div>');
$('[id^="photo_"]').each(function(){
$(this).change(function(){
$(this).next().val($(this).val());
});
});
});

can't get the dynamic textfield value using Jquery

I can't get the dynamic textfield value. Please see the below my jquery code.
I added onclick event while creating the textfield for LandMark. Please see the below code.
I am always getting undefined. Please help me.
function dynamicEvent() {
alert("dynamic event");
$(document).ready(function(){
alert("inside ajax --> dynamic");
var table = document.getElementById("dataTable");
alert("table-->"+table);
var rowCount = table.rows.length;
alert("rowCount-->"+rowCount);
alert("value of rowCount"+rowCount);
var uniqueId;
for (var i=rowCount;rowCount>7;i++){
uniqueId = i;
alert("inside for loop");
alert("uniqueId-->"+uniqueId);
var element = document.createElement("input");
uniqueId=uniqueId-1;
element.id = "t02Travelfrom" +uniqueId;
var tfrom=element.id;
alert("tfrom id-->"+tfrom);
var t02Travelfrom=$("tfrom").val();
alert(tfrom+"--value-->" +t02Travelfrom);
}
});
}
You have incorrect selector:
var t02Travelfrom=$("tfrom").val();
change to:
var t02Travelfrom=$("#" + tfrom).val();
$("tfrom") returning elements with tag tfrom
You need $(tfrom). You don't need double quotas.
