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

要从多个选中的复选框中获取一组值,请使用 jQuery map/get 函数:

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

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

这将返回带有检查值的数组,如下所示: ['1', '2']

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

You can do it like this,

你可以这样做,

$('.ads_Checkbox:checked')

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

您可以遍历它们each()并使用复选框值填充数组。

Live Demo

现场演示

To get the values of selected checkboxes in array

获取数组中选定复选框的值

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

Edit, using .map()

编辑,使用 .map()

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

您还可以使用jQuery.mapwithget()来获取选定复选框值的数组。

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

作为旁注,使用this.value而不是$(this).val()会提供更好的性能。

Live Demo

现场演示

$('#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();

回答by blasteralfred Ψ

You may try;

你可以试试;

$('#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.

这将在单个实例中返回所有复选框值。

Hereis a working Live Demo.

是一个有效的现场演示。

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

你也可以使用$('input[name="selector[]"]').serialize();. 它返回 URL 编码的字符串,如:“selector%5B%5D=1&selector%5B%5D=3”

回答by Maverick

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

由于您对所有复选框具有相同的类名,因此

   $(".ads_Checkbox") 

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

会给你所有的复选框,然后你可以使用每个循环来迭代它们

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

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

    var odata = {
