Pass javascirpt variable to asp

[zw1971]

How?

I have a javascript function like this:

<script language="JavaScript">
function processLists(list){
var selectedItems = getSelectedValues(list)
alert("You have selected = "+selectedItems+" items from list")
}


function getSelectedValues(list){
var len = list.length;
var ctr=0;
var values = new Array();
for(x=0;x<len;x++){
if(list[x].selected ){
values[ctr] = list[x].value;
ctr++;
}
}
return values;
}
</script>

How can I pass the variable selectedItems to the asp code on the same page when the form is submitted?

You can only do that if you pass the variable to the form when you submit.

So you make a hidden input in your form, and you make a function which gets triggered onSubmit:
<form onSubmit="ProcessSelectItems(this)">.......etc.....
<input type="hidden" name="selectItems" value="0" />
</form>

This function assigns the selectItems variable to the input field:


function ProcessSelectItems(oForm) {
oForm.selectItems.value = selectItems;
return true;
}

the selectItems form element will now be accessible in the Request.Form collection in ASP

Pelegk1,

Your proposed solution does not submit the form. Therefore, if you have more form elements which you would like to expose and handle in the asp page, this solution will only expose the selectItems and not via Request.Form but Request.QueryString.

zw1971,

Coming back to your question of permission. I believe the permissions on a specific file cannot be set via FTP. You have to have terminal access, whether it be an administrator manually setting the permissions, or you logging into the remote server using Terminal Services or PCAnywhere.

Often web hosts will leave a directory that has write access to it, eg. Brinkster says to put your db in the db folder.
