Hi Friends,
this problem really has me stumped.
I am using the body onLoad to initialise a couple of <SELECT> boxes. These boxes have a lot of options ( e.g. list of all countries) and using server-side coding to select the appropriate option is time consuming and also causes server time-outs.
So i handed it over to the client=side. the onload calls a procedure that loops thru the <SELECT> box and selects the option whose value matches the one i write into a hidden tag thru ASP. so i have a hidden field with value="India". then i would loop thru the <SELECT> box of all countries and when i find the option with the value "India", i set the selectedIndex to that, selected=true and defaultSelected=true. This works fine, but then i discovered another problem.
If i post this form and go onto the next step, when i press the Back button on the browser, and go back to the last page, the onLoad fires again and instead of retaining the value i might have selected ( supposing i changed the country to "United States" from "India"), it sets it back to "India". how can i prevent this??? any ideas?
I tried using a hidden field called "Back" and on form submit, setting its value to "Y". This value persists, when i come back to this page. so then the "United States" option stays selected but this only works in IE not NS......
any ideas on what i can do??
the basic solution i want is to know whether the pages is being loaded for the first time.. then i do the initialisation and if the page is being loaded from the cache by clicking the "back" button, i bypass the initilisation.
--- pseudo-code follows -----
<script language=JavaScript>
function setUp(){
if (fresh_load){
initialise_all_form_elements
}
}
</script>
<body onLoad="setUp();">
all input welcome
Thanks
