Analysis of checkbox Total selection problem based on jquery _jquery

In this paper, we analyze the whole selection of checkbox based on jquery. Share to everyone for your reference, specific as follows:

The most recent development project encountered a very strange problem, that is, checkbox selection and selection of all
A framework for using jquery. has been the use of

Detects the selected checkbox
$ (' input[name= ' abc ']:checked '). each (function () {})

But when I found out that I needed a full selection, I used

$ (' input[name= "abc"]). attr (' checked ', true);
$ (' input[name= "abc"]). attr (' checked ', false);

, it works when it's first loaded, then clicks on it and only shows itself.
But when clicked, view the source code, attribute checked has been added to the
Baffled, the last search, the original is the Attr property for checked, he will not change the DOM style, will only change its property values, jquery provides a way to replace, the following can be

$ (' input[name= "abc"]). Prop (' checked ', true);
$ (' input[name= "abc"]). Prop (' checked ', false);

But then again, I couldn't detect which element was clicked when I was not fully selected, and then I made a fuss over name.

$ (' input[name= ' abc[]:checked '). Each (function (i) {});
or
$ (' input[name= ' abc[] '). Each (function (i) {
  var flag = $ (this). Prop (' checked ');
  if (flag) {
   //$ (this) is the selected element
 }
})

Solve the problem.
