javascript - 如何在JavaScript中创建新行？(How do I create a new line in Javascript?)

Question

var i;
for(i=10; i>=0; i= i-1){
   var s;
   for(s=0; s<i; s = s+1){
    document.write("*");
   }
   //i want this to print a new line
   /document.write(?);

}

I am printing a pyramid of stars, I can't get the new line to print.(我正在打印星空金字塔，无法打印新行。)

Use the \n for a newline character.(将\n用作换行符。)

document.write(" "); You can also have more than one:(您还可以有多个：) document.write(" "); // 3 new lines! My oh my! However, if this is rendering to HTML, you will want to use the HTML tag for a newline:(但是，如果将其呈现为HTML，则需要将HTML标签用于换行符：) document.write("<br>"); The string Hello\n\nTest in your source will look like this:(源代码中的字符串Hello\n\nTest将如下所示：) Hello! Test The string Hello<br><br>Test will look like this in HTML source:(字符串Hello<br><br>Test在HTML源代码中将如下所示：) Hello<br><br>Test The HTML one will render as line breaks for the person viewing the page, the \n just drops the text to the next line in the source (if it's on an HTML page).(HTML页面将以换行符的形式呈现给查看页面的人， \n会将文本拖放到源代码的下一行（如果它在HTML页面上）。)
