Pass selected item in drop-list to a new window

omare · June 16th, 2003, 01:28 PM

Hi. I'd like to pass a selected item in a drop-down list to a new opened window (opened by a javascript "click here" link) .. so when the new window opens, that selected item in the form of the previous window is used to run a query on an ASP page.
This is the idea:

- Window 1 has drop list for user to select item
- after item is selected user clicks on a link
- that link opens a new window (an ASP page) which uses the item previously selected as a parameter for the query.

Any help anyone could provide would be GREATLY appreciated.

Thanx and regards everyone!

first page:

Code:

function open_new_window_function()
{
    var url;
    var selItem=document.form.items.selectedIndex;
    var item_parameter_value=document.form.items.options[selItem].value;
    url="hehe.asp?item_parameter=" + item_parameter_value;
    new_window = window.open(url,'','width=600,height=600,statusbar=yes,scrollbars=no'); 
}
</script>
<form name="form" ..>
...
    <select name="items">
        <option value=1>Item 1
        <option value=2>Item 2
        ...
    </select>
    &nbsp;&nbsp;
    <a href="#" onclick="open_new_window_function()">new window</a> 
...
</form>

And on ASP page you can handle selected item's value using
Request.QueryString("item_parameter").

You can either use Javascript to create the link from the elements when you open the window or you can havve a javascript function in the new window that grabs the value form the parent window and then submits the new window to the ASP page with the correct value.

I want to thank everyone for the help provided.

NNJ: -- you're the bestest!! it worked smoothly. Passing the parameter with java to the new window in such a way was exactly what I was having problems with.
So I want to sincerely thank you for your help.
My deepest respects go to you master.

Omare, I'm glad you've found a solution with which you're happy. Just for info, you can do this with just HTML, you don't need any javascript.

Code:

<form action='newWindowPage.asp' method='POST' target='_blank'>
  <select name='items'>
    <option value='1'>Item 1
    <option value='2'>Item 2
    ...
  </select>
  <input type='submit'>
</form>

It seems people often forget about the HTML 'target' attribute when they want to open a new window, and instead jump straight for js (I'm not saying js shouldn't be used for this, just that there are other options).
