问题描述
我正在编写一个网站,该网站接受至少 256 个字符/字符串的用户输入(针对该要求进行代码检查),提示(也检查)用户的转换选择(用户选择 ASCII 或 EBCDIC),并将转换后的文本字符串输出到页面上(根据用户的喜好以 ASCII 或 EBCDIC 格式)。该代码能够打印出用户输入(检查最少输入 256 个字符并确保用户在按下 Run! 按钮之前选择了一个单选按钮)。下面的代码有以下注释解释功能:
编码.js:
function myFunction() {
//Get both elements
const ascii = document.getElementById('ascii')
const ebcdic = document.getElementById('ebcdic')
let str = document.getElementById("text_id");
let a = "ASCII Code is == > ";
// Below checks to see if the user selects writed more than 255 chars
if (str.value.length < 256) {
console.log("null");
return null;
// prints and returns null if the user entered a string less than 256 characters
}
// Below checks to see if the user selects a radio button
let radio_selected = false;
document.querySelectorAll('input[type="radio"]').forEach(function (radio) {
if (radio.checked) {
radio_selected = true;
}
})
if (!radio_selected) {
console.log("The radio has not been checked,please select a button");
return;
}
//If one of the elements is checked it triggers a condition,if the other is cheked it triggers the other condition
if (ascii.checked) {
for (let i = 0; i < str.value.length; i++) {
document.getElementById("demo").innerHTML = document.getElementById("demo").innerHTML + str.value.charCodeAt(i);
}
}
else if (ebcdic.checked) {
for (let i = 0; i < str.value.length; i++) { //loop to check all values entered
//Code to convert text to EBCDIC,need help with this
}
}
}
1.html:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Converter for ASCII or EBCDIC</title>
<link href="style.css" rel="stylesheet" type="text/css"/>
<script src="encoding.js" defer></script>
</head>
<body style="text-align:center;">
<label for="text">Enter a text that is at least 256 characters long</label><br>
<input type="text" id="text_id" name="text" minlength="256">
<p>Select the following:</p>
<div>
<input id="ascii" type="radio" name="encoding" value="ascii">
<label for="ascii">ASCII</label>
</div>
<div>
<input id="ebcdic" type="radio" name="encoding" value="ebcdic">
<label for="ebcdic">EBCDIC</label>
</div>
<button onclick="myFunction()" type="button">"Run!"</button>
<label for="button">"Run!"</label>
<p id="demo" style="color:red;">
</body>
</html>
我一直在浏览此站点以查找任何文本/字符串(不是单个字符)转换为 EBCDIC 的迹象。到目前为止,我只看到了 EBCDIC 到 ASCII、反向和单个字符的转换,但没有看到字符串/文本到 EBCDIC 转换的迹象。
