I use NanoHTTPD as web server in my android, the following content is generated and I can browse the html in Firefox.

I hope to delete all selected items, I don't know how to write jQuery or JavaScript code to post the file names of all selected items to web server

and I don't know how NanoHTTPD handle get the posted file names.

Could you write some sample code for me? Thanks!

<input name="subBox" type="checkbox"  value="\SD\1.jpg"/>1.jpg <br/>
<input name="subBox" type="checkbox"  value="\SD\2.jpg"/>2.jpg <br/>
<input name="subBox" type="checkbox"  value="\SD\3.jpg"/>3.jpg <br/>
<input name="subBox" type="checkbox"  value="\SD\4.jpg"/>4.jpg <br/>

HelloCW

`of all selected items to web server`. To which webserver? And who is posting? – greenapps Nov 01 '16 at 07:55
`name="subBox" ` Only one `input` for thst name possible. – greenapps Nov 01 '16 at 07:56
Just let FireFox post the form. Then in your webserver look for the checked values. You dont need javascript or jquery. – greenapps Nov 01 '16 at 07:59
To greenapps: Could you give a sample code to post the form and let webserver to look the checked values? – HelloCW Nov 01 '16 at 08:06
`sample code to post the form`. You did not listen. I said 'let FireFox post the form'. No code needed for posting. – greenapps Nov 01 '16 at 08:08
Well of course you need a normal submit button and not use an onclick handler for it. – greenapps Nov 01 '16 at 08:17
Thanks! How can NanoHTTPD web server look for the checked values? – HelloCW Nov 01 '16 at 13:48
And more , I think I can set one name for all checkbox controls. – HelloCW Nov 01 '16 at 13:50
There is a `parameters` parameter in the `serve()` method of NanoHttpD. You need different checkbox names to begin with `subBox1, subBox2,..` – greenapps Nov 01 '16 at 14:05
Thanks! The user can modify the name of a checkbox in client using javascript, so I think it's not a good way to look for the checked values based control name. – HelloCW Nov 01 '16 at 14:31
And more, if there are many checkbox controls, how can you know the amount of the checkbox controls? subBox_ID1, subBox_ID2, subBox_ID3, ... subBox_IDn – HelloCW Nov 01 '16 at 14:35
You can check if a key exists in the keyset. In the Map. – greenapps Nov 01 '16 at 14:40
Letting the user change the name of an input looks like a bad idea. Only values is enough i think. – greenapps Nov 01 '16 at 14:42
You could start with just logging or printing all key =value pairs of the Map parameters. – greenapps Nov 01 '16 at 14:44
Thanks! if you don't make sure the amount of the checkbox controls, how can you look for all checkbox controls? – HelloCW Nov 01 '16 at 14:51
Just start with printing all key value pairs and you will get usefull ideas. – greenapps Nov 01 '16 at 14:52
