Android Webview form

i'm building a checkbox form with a submit button using webview(html/javascript). Once the form is submitted i need the selected check box values to be printed out.

Is there anyway to do this other than with toast, because once the values are rendered i need a way to send it to the printer.

If you are successfully doing it with a Toast, then that means you are accessing the values you need and can do anything you want with them. Paste in your code and we can look at it from there. :)

i decided to just print the results out with some javascript.

Is there an way in javascript to hold values even after reloading a page, kind of like a cookie in php. What i am doing is creating a dinning service menu selector for a local hospital. Once the meal is selected i build a counter to count the number of times the menu is selected (Regular : 4 Soft : 2 Bland : 15 Low Sodium : 10,ect)

I haven't done this in a long time, so I don't remember (or have) the code I used, but it is possible. Here's a hack I found with a quick search that looks pretty useful: http://stackoverflow.com/a/3338656/475217

cool, I finally got every thing working. I email myself to apk file to test the app, and when it's submitted the results pops up on new page but it will not stay it pops in then disappear. How can i get it to stay?

function processOrder(){
                //var x = document.forms[0].length;
                //document.write(x)

                    var checkBoxes = document.getElementsByTagName('input');
                            //alert(checkBoxes.length);
                        var param = "<strong>Meal Plan:</strong>"+"<br>";
                        for (var counter=0; counter < checkBoxes.length; counter++) {
                            if (checkBoxes[counter].type.toUpperCase()=='CHECKBOX' && checkBoxes[counter].checked == true) {
                                param += checkBoxes[counter].value  + "<br>";
                            }
                        }
                            document.write(param);

                }

By new page, do you mean a new page in your WebView? I can't tell from this code; perhaps if you pasted in the rest of the code in your Activity file?

Can you paste in all your HTML code? It looks like your processOrder() function is just writing out the meal plan HTML, but I'm wondering where it is trying to write it. Perhaps it's not being written in a way that's valid for HTML?
