Question

my json array store looks like this

[{
"role": "Executive Director",
"name": "David Z",
...},
{
"role": "Executive Director",
"name": "David Z",
...},
{
"role": "Non Executive Chairman",
"name": "Hersh M",
...},
{
"role": "Non Executive Director",
"name": "Alex C",
...},
{
"role": "Company Secretary",
"name": "Norman G",
...}]    

from this array comes a few html tables.

I loop through store to a draw html table as part of an ajax success function, like this

var table = '';
table += '<tr><td......</td>';
$.each(store, function(i, data) {
   // draw row...
   // draw row etc...
});
table += '</tr></tbody>';
$("#table_d").append(table);

however for one of the tables I want to skip the 2nd occurrence of David Z (or whatever name that occurs more than once)

var table = '';
table += '<tr><td......</td>';
$.each(store, function(i, data) {
    if (i > 0, store[i].name != store[i-1].name) { 
       // draw row...
       // draw row etc...
    }
});
table += '</tr></tbody>';
$("#table_d").append(table);

the array will always be ordered so I can compare store[i].name against store[i-1].name for a duplicate name.

so how can I correctly express if store[i].name != store[i-1].name run loop?

If I understand your question correctly, I think you just need to do this

if(i > 0)
{
    if(store[i].name != store[i-1].name)
    {
        //run code here
    }
}
