Select US State (in a var) from the populated state dropdown box

[pa2stepper]

I thought I had this solved from someone's else's question so I tried the code suggested. I got an error saying the property or method is not supported.

I have variable containing a state abbreviation.
I'm trying to get my already-populated drop-down to select the
state contained in the variable

document.editForm.state.options[document.editForm.state.selectedIndex].value=s;

How hard could this be - the state dropdown is already populated and will definitely find the 2-letter abbrev value - isn't there a one-liner to set it?

Thank you,
Mary

document.editForm.state.options[document.editForm.state.selectedIndex].value=s;

Would change the avlue of the currently selected option. I think you want somthing like:

var obj = document.forms['editForm].state;
for (i=0;i<obj.options.length;i++)
{
if (s==obj.options[i].value)
{
obj.options[i].selected=true;
obj.selectedIndex=i;
return;
}
}
alert('Stat not found');


The select options would have the abbreviation as their values:

<select name="state">
<option value="VA">Virgina</option>
<option value="MI">Michigan</option>
<option value="CO">Colorado</option>

Etc....

Hi - thanks for the reply. I tried both suggestions and neither worked. I can't figure this out.

I retrieved the state value from the database, "PA" for example, in a variable and simply want to select/highlight "PA" in the state drop down - the abbrev values are already in there and will always find its match. The state drop down looks like this.

<select name="state">
<option value=""></option>
<OPTION VALUE="AB">AB
<OPTION VALUE="AK">AK
<OPTION VALUE="AL">AL

Any further ideas come to mind?
Thanks!

Sorry about that CDino - it surely did work. I had to remove the return as it was causing an error (outside of function?) and then I removed the alert and now it works beautifully. I suspect, it's not working as efficiently without the return, probably selecting the match, then continuing down the line, but that's okay for now. Thanks a million for your help with this, CDino!
Best,

You are right about it being inefficient. The return should be break:

var obj = document.forms['editForm].state;
for (i=0;i<obj.options.length;i++)
{
if (s==obj.options[i].value)
{
obj.options[i].selected=true;
obj.selectedIndex=i;
break;
}
}

sorry about that.

[adios]

This is even more efficient - particularly for long lists:
