Loop Through Struct Values?

I have a struct like this:

Code JavaScript:

function Sampe(name, value, unit)
{
this.name = name;

[code]...

I then have an array of instances of this struct. I'm trying to create a search feature and need to loop through each instance of the struct in my array. Then I need to loop through each value in the struct and check it for a substring. If a substring is found the entire struct instance is printed and the search will skip to the next struct instance. Right now my loops are not working properly. The loop below with 'item' is not correct as 'item' just prints out a number (should be a text value).

Code JavaScript:

function searchView(text)
{
document.getElementById("searchResult").innerHTML = "";

[code]....
