I am using java script to provide a page to the client, in the page there are two checkboxes, i.e. "All countries" and "Asian Countries", so when i check the checkbox "Asian Countries" and click replot button, the page displays only asain counties but after some specific when the page reloads , it displays all other countries along with asian countries, and the checkbox "Asian Countries" is still selected, what i want is that after the page reloads it should display only the countries for which the checkbox was selected before. i am using window.location.href for providing the URL i.e.
window.location.href = 'filename.html?gmlat=' + map.getCenter().lat() + '&gmlng=' + map.getCenter().lng() + '&gmzoom=' + map.getZoom() + '&allcountries=' + plotOptChbox.checked + '&asiancountries=' + plotOptChbox.checked;
the above works fine under firefox and other browsers but not under IE 7/8/9 and we need it to work on IE. also i have already tried the below alternatives but issue not solved.
