Sort() 排序

<div style="font-size: 20px ;">JavaScript array.sort() 用來 陣列 元素排序，並回傳一個排序完成的新陣列，一般可以分為將 英文字母 或 單字排序 或 數字元素排列，sort 僅會將原本的陣列重新排序，不會另外產生一個新陣列，也就是說回傳的結果陣列就是原本的那個陣列。</div><br> <div id="S1" ></div><table border="3" style="width:100%;font-size: 20px ; "><tbody><tr><td> ﹤script> <font color="red">順序 分別為 a,b<font color="black"><br /> var A1= ["45", "76", "22", "14", "89", "78"];<br /> A1.sort(function(<font color="red">a,b<font color="black">){<br /> var x = a.toLowerCase();<br /> var y = b.toLowerCase();<br /> return a == b ? 0 : (a>b ? 1 : -1);}) <br />document.write(A1); <br />﹤/script> </td><td><script>var A1= ["45", "76", "22", "14", "89", "78"]; A1.sort(function(a,b){ var x = a.toLowerCase(); var y = b.toLowerCase(); return a == b ? 0 : (a>b ? 1 : -1);}) document.write(A1); </script></td></tr><!-------------22222---------------------------------------------><tr><td> ﹤script> <font color="red">逆序 分別為 b,a<font color="black"><br /> var A1= ["45", "76", "22", "14", "89", "78"];<br /> A1.sort(function(<font color="red">b,a<font color="black">){<br /> var x = a.toLowerCase();<br /> var y = b.toLowerCase();<br /> return a == b ? 0 : (a>b ? 1 : -1);}) <br />document.write(A1); <br />﹤/script> </td><td><script>var A1= ["45", "76", "22", "14", "89", "78"]; A1.sort(function(b,a){ var x = a.toLowerCase(); var y = b.toLowerCase(); return a == b ? 0 : (a>b ? 1 : -1);}) document.write(A1); </script></td></tr><!----------------3333333-------------------------------------><div id="S1" ></div><table border="3" style="width:100%;font-size: 20px ; "><tbody><tr><td> ﹤script> <font color="red">順序 分別為 a,b<font color="black"><br /> var A1= ["ss", "gg", "aa", "SS", "GG", "2","AA"];<br /> A1.sort(function(<font color="red">a,b<font color="black">){<br /> var x = a.toLowerCase();<br /> var y = b.toLowerCase();<br /> return a == b ? 0 : (a>b ? 1 : -1);}) <br />document.write(A1); <br />﹤/script> </td><td><script>var A1= ["ss", "gg", "aa", "SS", "GG", "2","AA"]; A1.sort(function(a,b){ var x = a.toLowerCase(); var y = b.toLowerCase(); return a == b ? 0 : (a>b ? 1 : -1);}) document.write(A1); </script></td></tr><!------------------------------------------------------------------------><tr><td> ﹤script> <font color="red">逆序 分別為 b,a<font color="black"><br /> var A1= ["ss", "gg", "aa", "SS", "GG", "2","AA"];<br /> A1.sort(function(<font color="red">b,a<font color="black">){<br /> var x = a.toLowerCase();<br /> var y = b.toLowerCase();<br /> return a == b ? 0 : (a>b ? 1 : -1);}) <br />document.write(A1); <br />﹤/script> </td><td><script>var A1= ["ss", "gg", "aa", "SS", "GG", "2","AA"]; A1.sort(function(b,a){ var x = a.toLowerCase(); var y = b.toLowerCase(); return a == b ? 0 : (a>b ? 1 : -1);}) document.write(A1); </script></td></tr> </tbody></table>
