按名称检查复选框的数量 [英] Getting amount of checkboxes checked by name

问题描述

我的复选框都被命名为 delete [] 。

  var count =（$（'＃form_store_setup input [name = delete]检查'）。 
  

...这完全不起作用：

  var count =（$（'＃form_store_setup input [name = delete []]：checked'）。 
  

解决方案

例如：

  var count =（$（'＃form_store_setup input [name =delete []]： ）。长度）; 
  

I'm trying to find out how many checkboxes have been checked but am having some trouble..

My checkboxes are all named delete[].

var count = ($('#form_store_setup input[name=delete]:checked').length);

...and this doesn't work at all:

var count = ($('#form_store_setup input[name=delete[]]:checked').length);

解决方案

Simply wrap delete[] in double quotes in your second example like this:

var count = ($('#form_store_setup input[name="delete[]"]:checked').length);
