循环通过复选框，并计数每个选中或取消选中 [英] Loop through checkboxes and count each one checked or unchecked

问题描述

我遇到了一个问题。这里有一个简短的解释。

I've run into a bit of an issue. Here's a brief explanation.

我有一个标准窗体上的12个复选框。我需要做的是循环遍历它们，并了解哪些被检查和哪些被取消检查。

I have 12 check boxes on a standard form. What I need to do is loop through each of them and learn which ones are checked and which ones are unchecked.

使用它，我可以构建一个字符串，然后输入到数据库字段。这里是一个例子。

Using this, I can then build a string which I then enter into a database field. Here is an example.

（选中1 - 已选中）

（选中2 - 未选中）

（选中3 - 已选中）

(Check1 - checked)
(Check2 - not checked)
(Check3 - checked)

1,0,1

到目前为止，我有了这一段代码。

So far, I've got this bit of code.

$('input[type=checkbox]').each(function () {
           if (this.checked) {
               console.log($(this).val()); 
           }
});

它完美地工作，除了它只带回检查的，而不是全部。

It works perfectly except that it only brings back the checked ones, not all.

对不起，newb的问题。

Sorry for the newb question. I'm kinda new to jquery.

推荐答案

要以您显示的格式完全建立结果字符串，可以使用：

To build a result string exactly in the format you show, you can use this:

var sList = "";
$('input[type=checkbox]').each(function () {
    sList += "(" + $(this).val() + "-" + (this.checked ? "checked" : "not checked") + ")";
});
console.log (sList);

但是，我同意@SLaks，我认为你应该重新考虑你的结构将会将其存储在您的数据库中。

However, I would agree with @SLaks, I think you should re-consider the structure into which you will store this in your database.

编辑：对不起，我错读了您正在查找的输出格式。这是一个更新：

EDIT: Sorry, I mis-read the output format you were looking for. Here is an update:

var sList = "";
$('input[type=checkbox]').each(function () {
    var sThisVal = (this.checked ? "1" : "0");
    sList += (sList=="" ? sThisVal : "," + sThisVal);
});
console.log (sList);
