下面框中为脚本显示区
Enter numbers here:
The sorted numbers are:
脚本说明: 第一步:把如下代码加入<head>区域中 <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:把如下代码加入区域中 <form> <table border=1> <td>Enter numbers here: <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>The sorted numbers are: <input type=text name=answers size=75></td> </tr> <tr> <td colspan=2 align=center><input type=button value="Sort!" onClick="doSort(this.form)"></td> </tr> </table> </form>
