我正在使用DataTables 来显示我输入的一些 XML 数据,但我正在寻找一种稍微不同的方法。我想在每一列上都有搜索框,并理想地用结果中的值填充它们。所以我会在每列上方有一个框,而不是他们页面上的“搜索”框(例如,用于渲染引擎:组合框中的 Trident、WebKit、Gecko 等)。我可以更改 DataTables jQuery 以允许这样做还是应该从头开始。这似乎令人生畏,但我对 jQuery 还是比较陌生。非常感谢任何回应。提前致谢。
编辑:感谢您的回复。我将 Datatables 与 predrag 建议的组合框一起使用,其中填充了列中的所有值(不仅仅是显示页面上的值),但是当我选择一个值时,它似乎不会触发重新加载网格的事件。这是我在页面上的 jQuery 代码:
<script type="text/javascript">
$(document).ready(function() {
<!-- Sorting and pagination -->
var oTable = $('#mainTable').dataTable( {
"bJQueryUI": true,
"sPaginationType": "full_numbers",
"bFilter": false
});
<!-- Filtering -->
$("thead td").each(function(i) {
this.innerHTML = fnCreateSelect(oTable.fnGetColumnData(i));
$('select', this).change(function() {
oTable.fnFilter($(this).val(), i);
});
});
});
</script>
此外,我已将这些函数添加到 jquery.dataTables.js 的底部,如下所示:http ://datatables.net/examples/api/multi_filter_select.html
(function ($) {
/*
* Function: fnGetColumnData
* Purpose: Return an array of table values from a particular column.
* Returns: array string: 1d data array
* Inputs: object:oSettings - dataTable settings object. This is always the last argument past to the function
* int:iColumn - the id of the column to extract the data from
* bool:bUnique - optional - if set to false duplicated values are not filtered out
* bool:bFiltered - optional - if set to false all the table data is used (not only the filtered)
* bool:bIgnoreEmpty - optional - if set to false empty values are not filtered from the result array

$.fn.dataTableExt.oApi.fnGetColumnData = function (oSettings, iColumn, bUnique, bFiltered, bIgnoreEmpty) {
// check that we have a column id
if (typeof iColumn == "undefined") return new Array();
// by default we only wany unique data
if (typeof bUnique == "undefined") bUnique = true;
// by default we do want to only look at filtered data
if (typeof bFiltered == "undefined") bFiltered = true;
// by default we do not wany to include empty values
if (typeof bIgnoreEmpty == "undefined") bIgnoreEmpty = true;
// list of rows which we're going to loop through
var aiRows;
// use only filtered rows
if (bFiltered == true) aiRows = oSettings.aiDisplay;
// use all rows
else aiRows = oSettings.aiDisplayMaster; // all row numbers
// set up data array
var asResultData = new Array();
for (var i = 0, c = aiRows.length; i < c; i++) {
iRow = aiRows[i];
var aData = this.fnGetData(iRow);
var sValue = aData[iColumn];
// ignore empty values?
if (bIgnoreEmpty == true && sValue.length == 0) continue;
// ignore unique values?
else if (bUnique == true && jQuery.inArray(sValue, asResultData) > -1) continue;
// else push the value onto the result data array
else asResultData.push(sValue);
}
return asResultData;
}
} (jQuery));
function fnCreateSelect(aData) {
var r = '<select><option value=""></option>', i, iLen = aData.length;
for (i = 0; i < iLen; i++) {
r += '<option value="' + aData[i] + '">' + aData[i] + '</option>';
}
return r + '</select>';
}
当我在 fnFilter 中设置断点并更改其中一个过滤器下拉框的值时,断点不会被命中,但是当我在 fnCreateSelect 中设置一个断点时它会被命中。难道我做错了什么?
