opening a new window

[new214]

Heya all, I want to know how to pass a variable across when opening a new window using javascript.
Ive got a text field and a button-and by changing properties of the button i can get it to open up a new window- however i want to know how i can pass the text field value so it appears in my pop-up window

Heres my code- im using asp

<tr> 
<td colSpan="5"><strong><font face="Arial" size="2">Search Criteria:</strong></td>
 
<td><input type="text" name="GSearch" </font></strong></td>
 
<td colSpan="20">
<INPUT TYPE="RADIO" NAME="DB" VALUE="1" CHECKED>Suppliers
</p>
 
<INPUT TYPE="RADIO" NAME="DB" VALUE="2" >Members 
</td>
 
<td>
<td colSpan="10"><input type="submit" name="submit" value="Submit" align="right" onClick="window.open
('Search Results.asp','mywindow','width=600,height=400')">
</td>
</tr>

thanks

Add an id for your text box, then pass it with the url in the new window:

<input type="text" name="GSearch" id="GSearch">

<input type="submit" name="submit" value="Submit" align="right" onClick="window.open
('Search Results.asp?Search='+document.getElementById('GSearch').value,'mywindow','width=600,height=400')">
 

Then in your searchresults page, just process the GET variable (you know how to do that in ASP, I assume).

Ive looked into this- but again i dont know. could you help me out?? Is is get function in asp or javascript???

The way I have described above, you should know ASP to deal with the variable. AFAIK, for a GET variable, you need to use the following:

Request.QueryString("GSearch")

Another way is to use Javascript in your ASP page, which uses window.opener:

window.opener.document.getElementById('GSearch').value;

would be a reference to your text box value in the popup window.

Ive tried both and they arent working- however when i use

Response.Write(Request.QueryString)

it works?? But 1 problem with this is the fact that it displays Search= along with the result. Any ideas on how to get rid of this???

Use

Response.Write(Request.QueryString("Search"))

instead.

thanks that is working- but 1 small point is how would i be able to pass more than 2 variables across using

<input type="submit" name="submit" value="Submit" align="right" onClick="window.open
('Search Results.asp?Search='+document.getElementById('GSearch').value,'mywindow','width=600,height=600')">

[acoder]

Use '&'+your search value pair, e.g.

onClick="window.open
('SearchResults.asp?Search='+document.getElementById('GSearch').value+'&myVal='+document.getElementById('SomeVal').value,...

well ive tried that way and it doesnt seem to be working.
What Im actually doing is trying to pass the value of a radio buttons either 1 or 2 across- along with the text. The text works fine but not the passing of the radio- heres how my original page code looks like-

<tr> 
<td colSpan="5"><strong><font face="Arial" size="2">Search Criteria:</strong></td>
 
<td><input type="text" name="GSearch" id="GSearch"></font></strong></td>
 
<td colSpan="20">
<INPUT TYPE="RADIO" NAME="DB" VALUE="1" CHECKED>Suppliers
</p>
 
<INPUT TYPE="RADIO" NAME="DB" VALUE="2" >Members 
</td>
 
 
<td>
<input type="submit" name="submit" value="Submit" align="right" onClick="window.open ('Search Results.asp Search='+document.getElementById('GSearch').value+'&DB1='+document.getElementById('DB').value, 'mywindow','width=600,height=600')">
</td>

And on my pop-up page- this is how I am requesting this:-

dim B
B=Request.Form("DB")
 
if B=1 then 
Response.Write("1")
 
else
Response.Write("2")
end if
 
H = (Request.QueryString("Search") & "<BR>")

Two points:

To use getElementById, you must set an id for the radio buttons.

Secondly, you're passing parameter DB1, not DB, so in your popup, you should check for DB1.
