if statement questions - Javascript

[ELFella]

I have been racking my brain trying to get a simple if statement inserted into DetailView.html that can check the a database value to see if it is empty and if so, do something........the reason I am being general about it is because I have multiple conditional statements I would like to put in.

Example:

if (database_value == '1')
{
code to be executed if condition is true
}
else
{
code to be executed if condition is not true
}

I am not a javascript expert, but where do I need to put my my script code......Can it be inline or do I have to call it externally. What files do I need to look in? Any examples?

I think one of the issues I am having is working around the database values that are in tables.

Any help would be greatly appreciated.

Thanks Erin

This isn't upgrade safe but...at the top of the DetailView.html put a param like {MY_JAVASCRIPT}. In DetailView.php do your condition. If database_value = 1 then assign your javascript code to run for MY_JAVASCRIPT else assign the other js code for MY_JAVASCRIPT. Either that or put the javascript on the html page and put something like if( {MY_VALUE} == 1 and assign MY_VALUE in the php page. See how variable assignments work in those pages to get a better idea.

Thanks eggsurplus,

I ended up putting in this code into DetailView.html and it worked like a champ......
This is figures out if a phone has an extension and adds the Ext: if it is present, if not it types nothing
I have been fighting with this for a few days and it came down to two ' marks enclosing the database field

<script type="text/javascript">
var ext1='0'

if (ext1 < '{PHONE1EXT_C}')
{
document.write("<b>Ext: </b>");
}
else
{
document.write("");
}
</script>

{PHONE1EXT_C}


Thanks again,
Erin
