Question

我试图在输出框中写出每个数组/函数后添加换行符，但似乎无法找到它的解决方案。我尝试将其添加为变量，评论等。任何想法？谢谢。例如：

1,2,3,4,5,6,7,8,9,11,22,23,25 "new line"
1,2,3,4,5,6,7,8,9,11,22,23,25 "new line"

码

  <!DOCTYPE HTML>
    <head>
        <title>Oppgave 1</title>
        <meta charset="utf-8" />
        <style>

        </style>
        <script>

            window.onload = oppstart;

            var output = "";
            var arr = [1,2,3,4,5,6,7,8,9,11,22,23,25];
            var sum = 0;



            function oppstart(){ 
            //Forlengs
                for (var i = 0; i < arr.length; i++) {
                skrivUt();
                }
            //Baklengs
                for(var i = arr.length-1; i >=0; i--) {
                skrivUt();
                }
            //Annethver
                for(var i = 0; i<arr.length; i+=2) {
                skrivUt();
                }
            //Mindre enn 10
                for(var i = 0; i < arr.length; i++)
                if(arr[i] < 10)
                skrivUt();
            //Partall
                for(var i = 0; i < arr.length; i++)
                if(arr[i]  % 2 === 0)
                skrivUt();

            function skrivUt(){
                output += arr[i] + " ";
                //sum += arr[i];
                document.getElementById("out").innerHTML = output;
                }

            }   


        </script>

    </head>
    <body>
        <p id="out"></p>

    </body>

这不是确切的答案这只是你的问题的例子只是使用＆＃34; \ n＆＃34;对于你脚本中的下一行

＆＃13;

   window.onload = oppstart;

            var output = "";
            var arr = [1,2,3,4,5,6,7,8,9,11,22,23,25];
            var sum = 0;



            function oppstart(){ 
            //Forlengs
                for (var i = 0; i < arr.length; i++) {
                skrivUt();
                  
                }
            //Baklengs
                for(var i = arr.length-1; i >=0; i--) {
                skrivUt();
                }
            //Annethver
                for(var i = 0; i<arr.length; i+=2) {
                skrivUt();
                }
            //Mindre enn 10
                for(var i = 0; i < arr.length; i++)
                if(arr[i] < 10)
                skrivUt();
            //Partall
                for(var i = 0; i < arr.length; i++)
                if(arr[i]  % 2 === 0)
                skrivUt();

            function skrivUt(){
                output += arr[i]+"\n";
                 alert(output);
                //sum += arr[i];
                document.getElementById("out").innerHTML = output;
                
                }

            }

        <p id="out"></p>

使用array.push而不是汇总值。

在数组后添加中断
