将循环变量调用到自动压缩选择中

尝试使用闭包：-

for (a = 1; a <= 2; a++) {
  (function(a) {
    $("#inp-" + a + "  .nama").autocomplete({
      source: function(request, response) {
        $.ajax({
          url: "states_remote.php",
          dataType: "json",
          data: {
            term: request.term
          },
          success: function(data) {
            response($.map(data, function(item) {
              return {
                value: item.nama,
                pangkat: item.pangkat,
                jabatan: item.jabatan,
                nip: item.nip
              };
            }));
          }
        });
      },
      minLength: 2,
      select: function(event, ui) {
        $("#inp-" + a + " .pangkat").val(ui.item.pangkat);
        $("#inp-" + a + " .nip").val(ui.item.nip);
        $("#inp-" + a + " .jabatan").val(ui.item.jabatan);
        $(this).next('.nama').focus();
      },
      html: true,
      open: function(event, ui) {
        $(".ui-autocomplete").css("z-index", 1000);
      }
    });
  })(a);
}

还有另一种方法，我觉得那会更好：

$(".nama").autocomplete({ // <----all the ".nama" element will be initialized
  source: function(request, response) {
    $.ajax({
      url: "states_remote.php",
      dataType: "json",
      data: {
        term: request.term
      },
      success: function(data) {
        response($.map(data, function(item) {
          return {
            value: item.nama,
            pangkat: item.pangkat,
            jabatan: item.jabatan,
            nip: item.nip
          };
        }));
      }
    });
  },
  minLength: 2,
  select: function(event, ui) {
    // event.target will be the ".nama" element and 
    // as per your code it seems that the elements are sibling 
    // elements of the ".nama", so use `.end()` to get back to 
    // $(event.target)
    $(event.target).siblings(".pangkat").val(ui.item.pangkat).end()
                   .siblings(".nip").val(ui.item.nip).end()
                   .siblings(".jabatan").val(ui.item.jabatan);
    $(event.target).focus();
  },
  html: true,
  open: function(event, ui) {
    $(".ui-autocomplete").css("z-index", 1000);
  }
});
