我有大量的数据jqgrid..我想隐藏拇指jqgrid这是鼠标滚轮向上和向下滚动条..数据是动态的，所以我给你基本的例子..有没有办法隐藏拇指jqgrid垂直滚动条只？

var data = [
  [48803, "DSK1", "", "02200220", "OPEN"],
  [48769, "APPR", "", "77733337", "ENTERED"],
  [48803, "DSK1", "", "02200220", "OPEN"],
  [48803, "DSK1", "", "02200220", "OPEN"],
  [48803, "DSK1", "", "02200220", "OPEN"],
  [48803, "DSK1", "", "02200220", "OPEN"],
  [48803, "DSK1", "", "02200220", "OPEN"],
  [48803, "DSK1", "", "02200220", "OPEN"],
  [48803, "DSK1", "", "02200220", "OPEN"],
  [48803, "DSK1", "", "02200220", "OPEN"],
  [48803, "DSK1", "", "02200220", "OPEN"],
  [48803, "DSK1", "", "02200220", "OPEN"],
  [48803, "DSK1", "", "02200220", "OPEN"],
  [48803, "DSK1", "", "02200220", "OPEN"],
  [48803, "DSK1", "", "02200220", "OPEN"],
];

$("#grid").jqGrid({
  datatype: "local",
  height: 250,
  colNames: ['Inv No', 'Thingy', 'Blank', 'Number', 'Status'],
  colModel: [{
    name: 'id',
    index: 'id',
    width: 60,
    sorttype: "int"
  }, {
    name: 'thingy',
    index: 'thingy',
    width: 90,
    sorttype: "date"
  }, {
    name: 'blank',
    index: 'blank',
    width: 30
  }, {
    name: 'number',
    index: 'number',
    width: 80,
    sorttype: "float"
  }, {
    name: 'status',
    index: 'status',
    width: 80,
    sorttype: "float"
  }],
  caption: "Stack Overflow Example",
  // ondblClickRow: function(rowid,iRow,iCol,e){alert('double clicked');}
});

var names = ["id", "thingy", "blank", "number", "status"];
var mydata = [];

for (var i = 0; i < data.length; i++) {
  mydata[i] = {};
  for (var j = 0; j < data[i].length; j++) {
    mydata[i][names[j]] = data[i][j];
  }
}

for (var i = 0; i <= mydata.length; i++) {
  $("#grid").jqGrid('addRowData', i + 1, mydata[i]);
}

更新我使用的是4.6.0版本的jqgrid..这只是一个例子忽略键，以及它如何在网格中输入数据..基本问题是隐藏滚动条的拇指
