按英国日期排序jQuery数据表并忽略空单元格

Question

如果以dd/mm/yyyy格式排序日期，如何将空单元格粘到底部？我的问题在这里（对年龄栏进行排序）：http://jsfiddle.net/dup75/11/

$('#hr_curriculum_interns').dataTable( {
    "aoColumns": [
        { "sType": "date-uk" },
        null,
        null,
        null,
        null,
        null,
        null,
        null,
        null
    ]
}); 

这里的着名代码见http://datatables.net/forums/discussion/4025/sorting-to-ignore-empty-cells，代码是：

    $.fn.dataTableExt.oSort['mystring-asc'] = function(x,y) {
    var retVal;
    x = x.replace(' ', '');
    y = y.replace(' ', '');

    if (x == y) retVal = 0;
    else if (x.substr(0,1) == "{" && y.substr(0,1) == "{") {
        if (x > y) retVal=  1;
        else retVal =  -1;
    }
    else if (x.substr(0,1) == "{") retVal =  1;
    else if (y.substr(0,1) == "{") retVal =  -1;

    else if (x > y) retVal=  1;
    else return -1;

    return retVal;
}
$.fn.dataTableExt.oSort['mystring-desc'] = function(y,x) {
    var retVal;
    x = x.replace(' ', '');
    y = y.replace(' ', '');

    if (x == y) retVal= 0;
    else if (x.substr(0,1) == "{" && y.substr(0,1) == "{") {
        if (x > y) retVal=  -1;
        else retVal =  1;
    }  
    else if (x.substr(0,1) == "{") retVal =  -1;
    else if (y.substr(0,1) == "{") retVal =  1;

    else if (x > y) retVal =  1;
    else return -1;

    return retVal;
 }

但它没有解决我在以dd / mm / yyy格式对我的列“age”进行排序时遇到的问题。 它只是以整数格式制作我的列，这不应该是因为它的日期格式。

请参阅下面的updated fiddle here或StackSnippet。基本上您需要实现自定义排序功能。以下是该排序函数的代码以及解释：

＆＃13;

＆＃13;

// add a set of custom sorting functions
jQuery.extend(jQuery.fn.dataTableExt.oSort, {
  "customdatesort-pre": function(a) {
    // returns the "weight" of a cell value
    var r, x;
    if (a === null || a === "") {
      // for empty cells: weight is a "special" value which needs special handling
      r = false;
    } else {
      // otherwise: weight is the "time value" of the date
      x = a.split("/");
      r = +new Date(+x[2], +x[1] - 1, +x[0]);
    }
    console.log("[PRECALC] " + a + " becomes " + r);
    return r;
  },
  "customdatesort-asc": function(a, b) {
    // return values are explained in Array.prototype.sort documentation
    if (a === false && b === false) {
      // if both are empty cells then order does not matter
      return 0;
    } else if (a === false) {
      // if a is an empty cell then consider a greater than b
      return 1;
    } else if (b === false) {
      // if b is an empty cell then consider a less than b
      return -1;
    } else {
      // common sense
      return a - b;
    }
  },
  "customdatesort-desc": function(a, b) {
    if (a === false && b === false) {
      return 0;
    } else if (a === false) {
      return 1;
    } else if (b === false) {
      return -1;
    } else {
      return b - a;
    }
  }
});
$(document).ready(function() {
  $('#hr_curriculum_interns').dataTable({
    "aoColumns": [{
        "sType": "customdatesort"
      },
      null,
      null,
      null,
      null,
      null,
      null,
      null,
      null
    ]
  });
});
