我知道这是重复的，但其他文档中的答案都不起作用
有人知道如何保留换行符而不是删除它们吗
我也尝试过使用.replace(/\n/g，"\r\ n"，但它不起作用
如有任何帮助，我们将不胜感激
这是代码：
<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
<script>
var a = setTimeout(dST, 2500);
var b;
var c;
var d;
var e;
var getResult;
function dST() {
$("#startText").remove();
}
function create() {
b = $("#linkedTo").val();
c = $("#nameIs").val();
d = $("#doesWhat").val();
if (c.indexOf('-') != -1) {
e = "customElements.define('" + c + "', class extends " + b + " { <br>connectedCallback() {<br>" + d + "<br>}<br>});";
$("#resultCode").html(e);
} else {
console.log("hello");
}
}
function downloadA() {
getResult = $("#resultCode").text();
var blob = new Blob([getResult], {
type: "text/javascript",
endings: "native"
});
download(blob, "javascript-file.js");
}
function download(blob, name) {
var url = URL.createObjectURL(blob),
div = document.createElement("div"),
anch = document.createElement("a");
document.body.appendChild(div);
div.appendChild(anch);
anch.innerHTML = " ";
div.style.width = "0";
div.style.hright = "0";
anch.href = url;
anch.download = name;
var ev = new MouseEvent("click", {});
anch.dispatchEvent(ev);
document.body.removeChild(div);
}
</script>
</head>
<body>
<p id="startText">This creates elements for you, but is still in beta stage.</p>
<input value="HTMLElement" id="linkedTo" type="text" readonly>
<input placeholder="aa-bb" id="nameIs" type="text">
<br>
<textarea rows="15" cols="57" placeholder="var p = document.body.createElement('P'); p.innerHTML = 'Hello, World!'; $('body').append('<p>Hello, World!</p>');" id="doesWhat" type="text"></textarea><br>
<button type="button" onclick="create(); $('#resultCode').css('border', '1px solid black'); if($('#nameIs').val().indexOf('-') != -1) {$('#downloadB').css('opacity', '1'); } else { $('#downloadB').css('opacity', '0'); }">Create</button>
<pre id="resultCode"></pre>
<button id="downloadB" type="button" onclick="downloadA()" style="opacity: 0">Download</button>
</body>
</html>我通过获取html并将所有<br>更改为rn来解决这个问题
这就是代码；
getResult = $("#resultCode").html();
getResult = getResult.replace(/<br>/g, "rn");
var blob = new Blob([getResult],{type:"text/html"});
