selecting an option in a select box from session variable

[Shreya Menon]

Hi,
I have a select box with values 200,300,400,500 ... 1000 in a select box in a form.,(lets call this as size)
In my program when the user logs in he has a size selected. I am storing this size in a session variable.
This page which is displayed after 4 pages gets the session value. Now I WANT TO MAKE THE VALUE IN THE SIZE VARIABLE TO BE THE SELECTED OPTION IN THE SELECT BOX.
Eg: If my user is selecting 500, then when my form in the 4 page loads the option that has to be selected in te checkbox has to be 500.
How can I do it ?
Thanks..

Set up a variable for each checkbox:
cb1 = ""
cb2 = "" , etc
Then later in the code check the session variable and reset the variable that applies:

If Session("value") = 100 then
     cb1 = "checked"
elseif Session("value") = 200 then
     cb2 = "checked"
....for all the possible values.

Then when yo write the checkboxes to the page just add the variables to them:
<input type=checkbox name=cb1 value='100' <%=cb1%>>
<input type=checkbox name=cb2 value='100' <%=cb2%>>
that should do it for you.
The code is vbscript

Dave,
Thanks for the response.
But mine is a SELECT BOX not a CHECK BOX.
I am going to try in the format that you suggested.
Any valuable suggestions for the SELECT BOX.
Thanks,
Maya

The principle is the same jus use the variable to set the selected index of the select box.

that should work

I already have had this kind of problem. Here the code I used
for(var i = 0;i < formName.selectBoxName.length;i++){
if ( formName.selectBoxName.options[i].value == sessionVariableValue){
formName.selectBoxName.selectedIndex = i;
break;
}
}
I don't know how you get the session variable but this code should help a little bit.
But if you don't set any value to the options of the selectBox, replace in the code formName.selectBoxName.options[i].value by formName.selectBoxName.options[i].text.
For information, options of a selectbox have 2 principal properties: text, which is displayed in the page, and value, which is sent to the url set in the property "action" of the form.

Thanks Xavier.
I shall try it and let you know.

Passing data from the server side to the client side is deceptively easy. For example:
var serverVar = "<%=sessionVariableValue%>";
for(var i = 0;i < formName.selectBoxName.length;i++){
if ( formName.selectBoxName.options[i].value == serverVar){
formName.selectBoxName.selectedIndex = i;
break;
}
}
This will allow you to also dynamically write the select box from the server side with the desired session level variable selected.
Hope that helps.

Will this work for selecting multiple selections from the select box? If so, how?
