One first page: A form SUBMIT goes to a subsequent page.
VBscript can see the hidden value with ... Request("myName") ...
How do I do the same thing in JavaScript.
alert(window.location.search);
or
alert(window.top.location.search.substring(1));
return nothing.
Well, you dont. When you submit a form it sends the values to a server, and the "server-side" reads that in vbscript as Request (Requested). If you want to let the requested value accessible to the Javascript, your server-side (subsequent) page must write that Request data back to the client-side, in other worlds, you have to write the requested value directily in the HTML that will be send back to the client browser.
Ex: In your ASP (Server-Side Subsequent VBScript file) you should write
Response.Write ("<script type=""text/javascript"">alert('" & Request("Data") & "')</script>")
<input type='hidden' id='hiddenId'/>
jQuery:
var value = $('#hiddenId').val();
alert(value);
Or
var value = document.getElementById('hiddenId').value;
alert(value);
In your form, you have to have the method set to GET.
<form method="GET" action="somepage">
<input type=hidden name=myHiddenValue />
</form>
Then on the next page, you can parse the search part of the url with a function like this.
function parseSearch(search, key) {
search = search.substring(1), items=search.split("&");
for (var i=0; i<items.length; i++) {
var item = items[i], parts = item.split("=");
if (parts[0] === key) {
return parts[1] || true;
}
}
}
parseSearch(location.search, "myHiddenValue"); // returns the hidden value
