我需要将用户输入的顺序从最低到最高排序并打印到我的 p id 中。
实现排序算法对n个整数进行排序(不使用数组的sort()方法)。
在输出中打印排序数组。
<!DOCTYPE html>
<html>
<head>
<title>User Input, Sort and Find!</title>
<style>
</style>
</head>
<body>
<h2>Enter 4 numbers user!</h2>
<p id="myprint"></p>
<button onclick="userInput()">Input your Numbers!</button>
<button onclick="searchInput()">Find an inputed number in your array! </button>
<script>
var numbers = [];
function userInput() {
for(var i = 0; i < 4; i++){
var num = prompt("Enter a number 1 at a time, from 1-9 until prompts ask you 4 times:");
if (isNaN(num)) {
alert("Enter a number!");
--i; // reset the counter for amount of numbers entered
}
if( !isNaN(num)) {
if( num % 1 != 0){
alert("Enter a whole number!")
--i; // reset the counter for amount of numbers entered
}else{
numbers.push(num);
}
}
}
document.getElementById("myprint").innerHTML = "Your numbers are" + numbers;
//Sort the array and print numbers in inner html
function bubbleSort(numbers) {
var length = numbers.length;
for (var i = (length - 1); i >= 0; i--) {
for (var j = (length - i); j > 0; j--) {
if (numbers[j] < numbers[j - 1]) {
var nmbr = numbers[j];
numbers[j] = numbers[j - 1];
numbers[j - 1] = nmbr;
}
}
}
}
function searchInput() {
}
}
</script>
</body>
</html>
最佳答案
看起来您的代码可以工作，只是您必须实际调用 bublesort 函数，然后该函数需要返回结果。
<body>
<h2>Enter 4 numbers user!</h2>
<p id="myprint"></p>
<button onclick="userInput()">Input your Numbers!</button>
<button onclick="searchInput()">Find an inputed number in your array! </button>
<script>
var numbers = [];
function userInput() {
for(var i = 0; i < 4; i++){
var num = prompt("Enter a number 1 at a time, from 1-9 until prompts ask you 4 times:");
if (isNaN(num)) {
alert("Enter a number!");
--i; // reset the counter for amount of numbers entered
}
if( !isNaN(num)) {
if( num % 1 != 0){
alert("Enter a whole number!")
--i; // reset the counter for amount of numbers entered
}else{
numbers.push(num);
}
}
}
numbers = bubbleSort(numbers);
document.getElementById("myprint").innerHTML = "Your numbers are" + numbers;
//Sort the array and print numbers in inner html
function bubbleSort(numbers) {
var length = numbers.length;
for (var i = (length - 1); i >= 0; i--) {
for (var j = (length - i); j > 0; j--) {
if (numbers[j] < numbers[j - 1]) {
var nmbr = numbers[j];
numbers[j] = numbers[j - 1];
numbers[j - 1] = nmbr;
}
}
}
return numbers;
}
function searchInput() {
}
}
</script>
</body>
