我正在尝试使用在 http://www.jqwidgets.com/display-a-grid-in-a-dropdown/ 中找到的代码来创建多列选择列表。列表已创建，但是在文档的初始加载时，文档顶部附近有一个 float 的垂直滚动条，如下图所示:

Floating Scroll Bar

列表打开后，栏会显示在需要的位置。当选择一个元素时，该栏就会消失。我的代码如下:

// Start Multicolume
function generatedata(rowscount) {
  // prepare the data
  var data = new Array();
  if (rowscount == undefined) rowscount = 100;
  var firstNames = ["Andrew", "Nancy", "Shelley", "Regina", "Yoshi", "Antoni", "Mayumi", "Ian", "Peter", "Lars", "Petra", "Martin", "Sven", "Elio", "Beate", "Cheryl", "Michael", "Guylene"];
  var lastNames = ["Fuller", "Davolio", "Burke", "Murphy", "Nagase", "Saavedra", "Ohno", "Devling", "Wilson", "Peterson", "Winkler", "Bein", "Petersen", "Rossi", "Vileid", "Saylor", "Bjorn", "Nodier"];
  var productNames = ["Black Tea", "Green Tea", "Caffe Espresso", "Doubleshot Espresso", "Caffe Latte", "White Chocolate Mocha", "Caramel Latte", "Caffe Americano", "Cappuccino", "Espresso Truffle", "Espresso con Panna", "Peppermint Mocha Twist"];
  var priceValues = ["2.25", "1.5", "3.0", "3.3", "4.5", "3.6", "3.8", "2.5", "5.0", "1.75", "3.25", "4.0"];
  for (var i = 0; i < rowscount; i++) {
    var row = {};
    var productindex = Math.floor(Math.random() * productNames.length);
    var price = parseFloat(priceValues[productindex]);
    var quantity = 1 + Math.round(Math.random() * 10);
    row["id"] = i;
    row["available"] = productindex % 2 == 0;
    row["firstname"] = firstNames[Math.floor(Math.random() * firstNames.length)];
    row["lastname"] = lastNames[Math.floor(Math.random() * lastNames.length)];
    row["productname"] = productNames[productindex];
    row["price"] = price;
    row["quantity"] = quantity;
    data[i] = row;
  }
  return data;
}
var data = generatedata(100);
var source = {
  localdata: data,
  datatype: "array"
};
var dataAdapter = new $.jqx.dataAdapter(source);
$("#jqxdropdownbutton").jqxDropDownButton({
  width: 150,
  height: 25
});
$("#jqxgrid").jqxGrid({
  width: 550,
  source: dataAdapter,
  columns: [{
    text: 'First Name',
    columntype: 'textbox',
    datafield: 'firstname',
    width: 90
  }, {
    text: 'Last Name',
    datafield: 'lastname',
    columntype: 'textbox',
    width: 90
  }, {
    text: 'Product',
    columntype: 'dropdownlist',
    datafield: 'productname',
    width: 180
  }, {
    text: 'Quantity',
    datafield: 'quantity',
    width: 70,
    cellsalign: 'right'
  }, {
    text: 'Price',
    datafield: 'price',
    cellsalign: 'right',
    cellsformat: 'c2'
  }]
});
$("#jqxgrid").bind('rowselect', function(event) {
  var args = event.args;
  var row = $("#jqxgrid").jqxGrid('getrowdata', args.rowindex);
  var dropDownContent = '<div style="position: relative; margin-left: 3px; margin-top: 5px;">' + row['firstname'] + ' ' + row['lastname'] + '</div>';
  $("#jqxdropdownbutton").jqxDropDownButton('setContent', dropDownContent);
});
$("#jqxgrid").jqxGrid('selectrow', 0);
// End Multicolume

  <div id="jqxdropdownbutton">
    <div style="border: none;" id="jqxgrid">
    </div>
  </div>
</body>

</html>

我需要启用哪些参数才能在加载时看不到滚动条？

最佳答案

我想通了...

我现在使用以下代码:

	 // Start Multicolume
	 // prepare the data
	var data = new Array();
	var firstNames = ["Andrew", "Nancy", "Shelley", "Regina", "Yoshi", "Antoni", "Mayumi", "Ian", "Peter", "Lars", "Petra", "Martin", "Sven", "Elio", "Beate", "Cheryl", "Michael", "Guylene"];
	var lastNames = ["Fuller", "Davolio", "Burke", "Murphy", "Nagase", "Saavedra", "Ohno", "Devling", "Wilson", "Peterson", "Winkler", "Bein", "Petersen", "Rossi", "Vileid", "Saylor", "Bjorn", "Nodier"];
	var productNames = ["Black Tea", "Green Tea", "Caffe Espresso", "Doubleshot Espresso", "Caffe Latte", "White Chocolate Mocha", "Cramel Latte", "Caffe Americano", "Cappuccino", "Espresso Truffle", "Espresso con Panna", "Peppermint Mocha Twist"];
	var priceValues = ["2.25", "1.5", "3.0", "3.3", "4.5", "3.6", "3.8", "2.5", "5.0", "1.75", "3.25", "4.0"];
	for (var i = 0; i < 100; i++) {
	  var row = {};
	  var productindex = Math.floor(Math.random() * productNames.length);
	  var price = parseFloat(priceValues[productindex]);
	  var quantity = 1 + Math.round(Math.random() * 10);
	  row["firstname"] = firstNames[Math.floor(Math.random() * firstNames.length)];
	  row["lastname"] = lastNames[Math.floor(Math.random() * lastNames.length)];
	  row["productname"] = productNames[productindex];
	  row["price"] = price;
	  row["quantity"] = quantity;
	  row["total"] = price * quantity;
	  data[i] = row;
	}
	var source = {
	  localdata: data,
	  datatype: "array"
	};
	$("#jqxdropdownbutton").jqxDropDownButton({
	  width: 150,
	  height: 25
	});
	$("#jqxgrid").jqxGrid({
	  width: 500,
	  source: source,
	  theme: 'energyblue',
	  columns: [{
	    text: 'First Name',
	    datafield: 'firstname',
	    width: 100
	  }, {
	    text: 'Last Name',
	    datafield: 'lastname',
	    width: 100
	  }, {
	    text: 'Product',
	    datafield: 'productname',
	    width: 180
	  }, {
	    text: 'Quantity',
	    datafield: 'quantity',
	    width: 80,
	    cellsalign: 'right'
	  }, {
	    text: 'Unit Price',
	    datafield: 'price',
	    width: 90,
	    cellsalign: 'right',
	    cellsformat: 'c2'
	  }, {
	    text: 'Total',
	    datafield: 'total',
	    width: 100,
	    cellsalign: 'right',
	    cellsformat: 'c2'
	  }]
	});

	$("#jqxgrid").bind('rowselect', function(event) {
	  var args = event.args;
	  var row = $("#jqxgrid").jqxGrid('getrowdata', args.rowindex);
	  var dropDownContent = '<div style="position: relative; margin-left: 3px; margin-top: 5px;">' + row['firstname'] + ' ' + row['lastname'] + '</div>';
	  $("#jqxdropdownbutton").jqxDropDownButton('setContent', dropDownContent);
	});
	$("#jqxgrid").jqxGrid('selectrow', 0);
	 // End Multicolume
