How to get multiple checkbox values using jQuery?

To get an array of values from multiple checked checkboxes, use jQuery map/get functions:

$('input[type=checkbox]:checked').map(function(_, el) {
    return $(el).val();
}).get();

This will return array with checked values, like this one: ['1', '2']

Here is working example on jsfiddle: http://jsfiddle.net/7PV2e/

You can do it like this,

$('.ads_Checkbox:checked')

You can iterate through them with each() and fill the array with checkedbox values.

Live Demo

To get the values of selected checkboxes in array

var i = 0;
$('#save_value').click(function () {
       var arr = [];
       $('.ads_Checkbox:checked').each(function () {
           arr[i++] = $(this).val();
       });      
});

Edit, using .map()

You can also use jQuery.map with get() to get the array of selected checkboxe values.

As a side note using this.value instead of $(this).val() would give better performance.

Live Demo

$('#save_value').click(function(){
    var arr = $('.ads_Checkbox:checked').map(function(){
        return this.value;
    }).get();
}); 

$('input:checked').map(function(i, e) {return e.value}).toArray();

You can get them like this

$('#save_value').click(function() {
    $('.ads_Checkbox:checked').each(function() {
        alert($(this).val());
    });
});

jsfiddle

You may try;

$('#save_value').click(function(){
    var final = '';
    $('.ads_Checkbox:checked').each(function(){        
        var values = $(this).val();
        final += values;
    });
    alert(final);
});

This will return all checkbox values in a single instance.

Here is a working Live Demo.

Since u have the same class name against all check box, thus

   $(".ads_Checkbox") 

will give u all the checkboxes, and then you can iterate them using each loop like

$(".ads_Checkbox:checked").each(function(){
   alert($(this).val());
});

Also you can use $('input[name="selector[]"]').serialize();. It returns URL encoded string like: "selector%5B%5D=1&selector%5B%5D=3"

try this one.. (guys I am a new bee.. so if I wrong then I am really sorry. But I found a solution by this way.)

var suggestion = [];
$('#health_condition_name:checked').each(function (j, ob) {

    var odata = {
        health_condition_name: $(ob).val()
    };

    health.push(odata);
});

Try getPrameterValues() for getting values from multiple checkboxes.

$(document).ready(function() {
    $("#save_value").click(function(){
        var arr = [];
        $.each($("input[class='ads_Checkbox']:checked"), function(){
            arr.push($(this).val());
        });
        alert("Your selected options are: " + arr.join(","));
        });
});

You need this:

var allCheckboxesChoosed = [];  
$("input[name='myCheckbox[]']:checked").each(function(){  
    var oneCheck = {  
        checkId: $(this).attr("id"),  
        value: $(this).val()  
    };  
    allCheckboxesChoosed.push(oneCheck);  
});

console.log('allCheckboxesChoosed', allCheckboxesChoosed);
