使用冒泡发排序。只需要在文本框内输入一串数字，点击排序按钮即可
第一步：
在<head>区添加以下代码
<SCRIPT LANGUAGE="JavaScript">
/*****************************************************

<!-- Begin
function doSort(form) {
nanExists = false;
inputString = form.numbers.value;
inputNumbers = inputString.split(",");
for (var i = 0; i < inputNumbers.length; i++) {
inputNumbers[i] = parseInt(inputNumbers[i], 10);
if (isNaN(inputNumbers[i])) {
nanExists = true;
break;
}
}
inputNumbers = bubbleSort(inputNumbers, 0, inputNumbers.length - 1);
if (nanExists)
form.answers.value = "Invalid Input, numbers must be seperated by commas";
else
form.answers.value = resultString(inputNumbers, 0);
}
function resultString(inputArray, num) {
if ((inputArray.length - 1) >= num)
return (inputArray[num] + "," + resultString(inputArray,(num + 1)));
else return "";
}
function bubbleSort(inputArray, start, rest) {
for (var i = rest - 1; i >= start; i--) {
for (var j = start; j <= i; j++) {
if (inputArray[j+1] < inputArray[j]) {
var tempValue = inputArray[j];
inputArray[j] = inputArray[j+1];
inputArray[j+1] = tempValue;
}
}
}
return inputArray;
}
// End -->
</script>
第二步：
在<body>区添加以下代码
<form> <table border=1> <td>输入要排序的数字: <input type=text name=numbers size=75 value="4,2,5,1,7,8,9,3,6,3,6,2,9,8,5,2,6,7,3,4,5,6,8,1,9,4,3,6,2,5,8,4"></td> <tr> <td>排序结果: <input type=text name=answers size=75></td> </tr> <tr> <td colspan=2 align=center><input type=button value="排序" onClick="doSort(this.form)"></td> </tr> </table> </form>
