如何使用 jQuery 通过 Ajax 发送复选框数组的值? [英] How to send the values of an array of checkboxes through Ajax using jQuery?

问题描述

我有一个包含很多表单域(12 x n 行)的表单.每行的第一个字段(代表一个产品)是一个类似于这样的复选框:

I have a form with a lot of form fields (12 x n rows). The first field in each row (which represents a product) is a checkbox that resembles this:

<input type="checkbox" class="ids" name="ids[]" value="1">

每个复选框的值都是唯一的.

The value of each checkbox is unique.

我想要做的是将检查的值发送到 PHP 脚本以通过 Ajax 进行处理.我遇到的问题是正确获取服务器的 ID.我尝试过使用多种方法，包括:

What I am trying to do is send checked values to a PHP script for processing via Ajax. What I am am having issues with is getting the IDs to the server properly. I have tried using several things including:

$('.ids:checked').serialize();

和

var ids = [];
$('.ids:checked').each(function(i, e) {
    ids.push($(this).val());
});

$.ajax({
    url: "stub",
    type: "post",
    dataType: "json",
    data: {
        'ids[]': 'ids[]='+ids.join('&ids[]=')
    },
    success: function(data) {
        // stub
    }
});

但是这些都导致在服务器上得到这个:

But these both result in getting this on the server:

ids[]=104&ids;[]=105

我可以序列化整个表单并将其发送，但这可能会导致发送大量未使用的数据.

I could serialize the whole form and send it over but that could result in a lot of data being sent that is going to be unused.

如何只将 delete[] 的值发送到服务器?理想情况下，PHP 将其识别为数组?

How do I send only the values of delete[] to the server? Ideally in a way that PHP recognizes it as an array?

(我已经通过将 ID 作为逗号分隔的字符串发送来解决了这个问题，但我想知道如何实现这一点，因为我花了足够的时间试图弄清楚).

(I have worked around it by sending the IDs over as a comma delimited string but would like to know how to accomplish this since I spent enough time trying to figure it out).

推荐答案

这对我来说很好

<input type="checkbox" class="ids" name="ids[]" value="2">
<input type="checkbox" class="ids" name="ids[]" value="3">
<input type="checkbox" class="ids" name="ids[]" value="4">
<input type="checkbox" class="ids" name="ids[]" value="5">
<input type="checkbox" class="ids" name="ids[]" value="6">

<div id="response"></div>
<button id="submit">Submit</button>

<script>

$('#submit').click(function() {

$.ajax({
    url: "stub.php",
    type: "post",
    data: $('.ids:checked').serialize(),
    success: function(data) {
    $('#response').html(data);
    }
});


});
</script>

然后在 stub.php

Then on stub.php

var_dump($_POST);
