在javascript中存储已勾选的复选框值

-1

我的每个div都包含多个复选框，并且我有这样的几个div。我想保持跟踪选中哪个复选框以及它们各自的div。我试图将它存储在一个多维数组中，但它不适合。如果您有任何其他想法，然后PLZ与我分享。在javascript中存储已勾选的复选框值

你可以发布你的代码吗？ – nandu 2012-04-13 11:47:34

请你详细说明一下吗？向我们展示您的html并通过“跟踪选定的复选框”来描述您想实现的目标。为什么你必须存储它们 - 例如，是不是在DOM中查看它们是足够的？ – 2012-04-13 11:48:26

您是否希望存储复选框的ID以及它在选中时的div（真） – 2012-04-13 11:48:45

一件事笏你可以尝试为t将其存储为JSON对象。例如，说div1，div2和div3每个包含2个复选框。然后JSON对象将只包含选中的复选框，如

var jsonObject = [{ "divName" : "div1", "selectedCheckBoxes" : [{"checkbox1"}] }, [{ "divName" : "div2", "selectedCheckBoxes" : [{"checkbox2"}] }]等等。

这个link会帮助你理解JSON对象。

我没有更多关于json的想法我应该创建不同的json文件 – Pranali 2012-04-13 12:21:50

一些简单的例子在此链接中给出 - http://stackoverflow.com/questions/920930 /如何到创建JSON的逐JavaScript的for循环。希望这可以帮助。 – Krishna 2012-04-13 12:38:10

DEMO：

$(function() { 
      $('#myButton').click(function() { 
       $('input:checkbox:checked').each(function(i) { 
        alert(this.value); 
        var id= $(this).parent().attr('id') 
        alert(id); 
      }); 
     }); 
});

一种方式做是使用JSON商店。它有一个称为checked的事件，它返回一个布尔值。另外，请通过以下链接： http://docs.sencha.com/ext-js/3-4/#!/api/Ext.form.Checkbox-event-check
