function parameter parsing

[mickeyg]

I am attempting to write a generic function searcharray.
However when I return from it, my value is undefined.
I am expecting my array length to be 3 but is 9 when I use the alert in my function.
Is anything wrong with my syntax?

Everything works find when I use my hardcoded inline code instead of calling this function.

function searcharray(arrayname, arrayfield, matchvalue, searchfield) {
alert(arrayname.length);
// loop through array to find and return a value
for (var i = 0; i < arrayname.length; i++) {
if (arrayname.arrayfield == matchvalue) {
return arrayname.searchfield;
}
}
}

function dfltdonation() {
<snip>
var mydfltdonation = searcharray(&quot;publarray&quot;, &quot;subscription&quot;, mysub, &quot;dfltdonation&quot; alert(mydfltdonation);
<snip>
}

Thanks...must be simple I have overlooked

Your 'arrayname' is a string so indeed its length is 9. Remove the quotes in teh call. You want to pass the array not the string 'publarray'.

When I call my function I am not finding a match. However, if I just use my commented out loop, I find the correct match.

function dfltreason() {
var mydfltreason = searcharray(publarray,&quot;subscription&quot;,mysub,&quot;dfltreason&quot;
/****
// loop through publication array to find default reason code
for (var i = 0; i < publarray.length; i++) {
if (publarray.subscription == mysub) {
mydfltreason = publarray.dfltreason;
}
}

}

function searcharray(myarrayname,myarrayfield,mymatchvalue,mysearchfield) {
// loop through array to find and return a value
for (var i = 0; i < myarrayname.length; i++) {
if (myarrayname.myarrayfield == mymatchvalue) {
return myarrayname.mysearchfield;
}
}
}
