this is how I would do it!
<script type="text/javascript">
jQuery.ajat=function(url){
var results = []
jQuery.ajax({
async:false,
url:url,
dataType: "text",
complete:function(res) {
var data = res.responseText;
var a = data.split(/\n/)
var headings = a[0].split(/\t/)
for (var i = 1; i < a.length;
i++){
var line =
a[i].split(/\t/)
var obj = {}
for (var j = 0; j <
line.length; j++){
obj[headings[j]] = line[j]
}
results.push(obj)
}
}
})
return results
}
$(function(){
var x = $.ajat('data.txt')
$.log(x)
});
</script>
