如何实现“NaturalSort”中的jqGrid(How to Implement 'Na

我开始了我的搜索，以实现“NaturalSort”在jqGrid的，我有NaturalSort Javascript代码如下：

this.naturalSort = function (a, b) {
    var re = /(^-?[0-9]+(\.?[0-9]*)[df]?e?[0-9]?$|^0x[0-9a-f]+$|[0-9]+)/gi,
        sre = /(^[ ]*|[ ]*$)/g,
        dre = /(^([\w ]+,?[\w ]+)?[\w ]+,?[\w ]+\d+:\d+(:\d+)?[\w ]?|^\d{1,4}[\/\-]\d{1,4}[\/\-]\d{1,4}|^\w+, \w+ \d+, \d{4})/,
        hre = /^0x[0-9a-f]+$/i,
        ore = /^0/,
        i = function (s) { return naturalSort.insensitive && ('' + s).toLowerCase() || '' + s },
    // convert all to strings strip whitespace
        x = i(a).replace(sre, '') || '',
        y = i(b).replace(sre, '') || '',
    // chunk/tokenize
        xN = x.replace(re, '\0$1\0').replace(/\0$/, '').replace(/^\0/, '').split('\0'),
        yN = y.replace(re, '\0$1\0').replace(/\0$/, '').replace(/^\0/, '').split('\0'),
    // numeric, hex or date detection
        xD = parseInt(x.match(hre)) || (xN.length != 1 && x.match(dre) && Date.parse(x)),
        yD = parseInt(y.match(hre)) || xD && y.match(dre) && Date.parse(y) || null,
        oFxNcL, oFyNcL;
    // first try and sort Hex codes or Dates
    if (yD)
        if (xD < yD) return -1;
        else if (xD > yD) return 1;
    // natural sorting through split numeric strings and default strings
    for (var cLoc = 0, numS = Math.max(xN.length, yN.length); cLoc < numS; cLoc++) {
        // find floats not starting with '0', string or 0 if not defined (Clint Priest)
        oFxNcL = !(xN[cLoc] || '').match(ore) && parseFloat(xN[cLoc]) || xN[cLoc] || 0;
        oFyNcL = !(yN[cLoc] || '').match(ore) && parseFloat(yN[cLoc]) || yN[cLoc] || 0;
        // handle numeric vs string comparison - number < string - (Kyle Adams)
        if (isNaN(oFxNcL) !== isNaN(oFyNcL)) { return (isNaN(oFxNcL)) ? 1 : -1; }
        // rely on string comparison if different types - i.e. '02' < 2 != '02' < '2'
        else if (typeof oFxNcL !== typeof oFyNcL) {
            oFxNcL += '';
            oFyNcL += '';
        }
        if (oFxNcL < oFyNcL) return -1;
        if (oFxNcL > oFyNcL) return 1;
    }
    return 0;
};

我试过，但没有找到一种方法，通过jqGrid的消耗上面的代码。任何人都可以指导我如何才能通过上面的代码或任何其它的方式实现“NaturalSort”。

在这方面的任何帮助将非常感激！

托尼 - jqGrid的创建者已经增加了新的功能来处理这里定制排序： https://github.com/tonytomov/jqGrid/commit/6131d8a464243d1120278f99a9cdf053246b518f

这将是在未来的jqGrid的版本中提供。这里是由托尼以下修改代码来处理NaturalSort顺序：

...jqGrid({
...
data: mydata,
...
colModel : [ 
...
{"name": "field1",...,"sortfunc": naturalSort, ...},
...
],
...
});

请注意，排序功能，您将需要通过3个PARAMATERS，其中3个参数是升序排序顺序1和-1的下降。在这种情况下，你naturalSort功能应该有3个参数。下面是我修改后的代码。
