I hope you can read it carefully and be able to achieve something!

Demand:

1 dynamically generate a set of checkbox (data source is DB or memory collection)

When the 2post is submitted, the backend can get it in time.

4 avoid producing a large amount of viewstate

Solution: use repeater+input (checkbox) + input (hidden)

Html code

The copy code is as follows:

Note: try to write the anonymous function code in OnClick on the top of the page.

Js code

The copy code is as follows:

$(": Hidden [name = 'reportType']") .each (function () {

Var obj = $(this) .prev ()

If (obj.attr ('checked')) {$(this) .val (obj.val ());}

});

Get when the post is submitted by the backend

The copy code is as follows:

String [] _ str = Request ["reportType"] .split (',')

String data will inevitably have empty strings. Be careful to delete them, otherwise there will be a type conversion exception when unpacking.
