我使用此代碼排序自然的列:
-2
-1
0
1
2
function naturalSort(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/,
// convert all to strings and trim()
x = a.toString().replace(sre, '') || '',
y = b.toString().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;
// 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;
};
// Natural Sorting
jQuery.fn.dataTableExt.oSort['natural-asc'] = function (a, b) {
return naturalSort(a, b);
};
jQuery.fn.dataTableExt.oSort['natural-desc'] = function (a, b) {
return naturalSort(a, b) * -1;
};
它工作正常,但如果我把一個DIV與標題爲內容在數字之前,它不能正常工作:
<div title='juhu'>-1</div >
<div title='juhu'>-2</div >
<div title='juhu'>0</div >
<div title='juhu'>1</div >
<div title='juhu'>2</div >
有沒有人有解決這個問題的方法?
JavaScript應該刪除div並選擇數字... – Butters
