取消选中复选框会触发事件 [英] On unchecking a checkbox trigger an event

问题描述

我有以下代码

I have following code

<li>
    <input type="checkbox" value="1" class="filter" name="Bedroom">
    <a id="1" href="javascript:void(0)" class="filter1"> Bedroom </a>           
</li>

<li>
    <input type="checkbox" value="7" class="filter" name="Living Room">
    <a id="7" href="javascript:void(0)" class="filter1"> Living Room </a>           
</li>

<li>
    <input type="checkbox" value="6" class="filter" name="Corridor">
    <a id="6" href="javascript:void(0)" class="filter1"> Corridor </a>          
</li>
</ul>

java脚本

<script>

    var id='';
    jQuery('.filter').click(function(){          

    jQuery('.filter').each(function(){      
        if(jQuery(this).attr('checked'))
        {
            id+=jQuery(this).val()+',';
        }               
    });
       alert(id);

        jQuery.get('<?php echo $this->getUrl('some url') ?>',{cat:id},function(data){   
      jQuery('#id').html(data);
        });
    });         
    </script>

假设我检查了一个复选框，我得到了该复选框的id。

Suppose I checked a checkbox I am getting the id of that check box.

id+=jQuery(this).val()+',';

如何从ID变量中取消复选框的元素ID？

How to remove the the id of element on unchecking a checkbox from id variable ?

我试图做一个ajax调用，当我点击复选框时，我应该得到
a url，其中包含复选框的id例子... /？cat = 7 ％2C7％2C6％2C

I am trying to make an ajax call,When I click on the check boxes then I should get a url containing the ids of the checkboxes example .../?cat=7%2C7%2C6%2C

以及取消选中复选框的ID不应存在

and on unchecking the check boxes those check boxes ids should not be present

推荐答案

您将在列表中创建重复ID，一个简单的解决方案就是每次重新创建ID字符串像

You will be creating duplicate ids in the list, an easy solution is to recreate the id string every time like

var id;
var $checks = jQuery('.filter').change(function () {
    id= $checks.filter(':checked').map(function () {
        return this.value;
    }).get().join(', ');
    console.log(id);
});
