使用jQuery进行表操作

Question

我正在使用DataTables 显示我已经进入的一些XML数据,但我正在寻找一种稍微不同的方法.我想在每列上都有搜索框,理想情况下用搜索结果中的值填充它们.所以我们在页面上方的"搜索"框中不会显示一个带有值的框(Say,for Rending)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,但我仍然是jQuery的新手.任何回复都非常感谢.提前致谢.

编辑:感谢您的回复.我正在使用带有组合框的数据表作为predrag建议,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,它似乎没有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>

另外,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
* Author:   Benedikt Forchhammer <b.forchhammer /AT\ mind2.de>
*/
$.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,断点不会被击中,但是当我在fnCreateSelect中设置断点时它会被击中.难道我做错了什么？
