在此示例中，我想generate_html()在单独的选项卡中显示方法中生成的 html。

预期：显示一个新选项卡，显示渲染的 html 一个单词匹配游戏。

实际：我创建了一个渲染 html 的方法。我的程序处理一组输入，这些输入代表单词匹配游戏的键和描述。当用户单击 generate_html 时，将使用要生成的 html 创建一个 textarea。然后，当用户单击 Render html 时，来自 textarea 的 html 将在下面呈现。

function render_html(){
      // was html rendered?
      if(!htmlRendered){
        textarea  = document.getElementById("generated_html_textarea");
        generated_html = textarea.value;
        maincontentstyle = document.getElementById("maincontentstyle");
        rendered_html = document.createElement("div");
        rendered_html.setAttribute("id","rendered_html");
        rendered_html.setAttribute("style","border: 1px solid #EB0D1B; width: 360px; font-family: courier; font-size: 100.5%; margin: 0px auto; border: 1px; text-align: center; margin-top: 5px;");
        rendered_html.innerHTML +=  generated_html;
        rendered_html.innerHTML +='<span style="padding: 3px"> <button id ="one" class="button" type="button" onClick="show_answer()">Show Answer</button> <button id = "resetButton" class="button" type="button" onClick="reset()">Reset</button> </span>';
        maincontentstyle.appendChild(rendered_html);
        htmlRendered = true;
      }
      update_draggy_boxes();
    }

新选项卡应显示来自变量的内容rendered_html。

我正在寻找某种方式来实现这个目标。代码很简单。任何帮助将不胜感激。

见最后几行。window.open('')作品。

function render_html(){
      // was html rendered?
      if(!htmlRendered){
        textarea  = document.getElementById("generated_html_textarea");
        generated_html = textarea.value;
        console.log(generated_html);
        var new_window = window.open('');
        maincontentstyle = document.getElementById("maincontentstyle");
        rendered_html = document.createElement("div");
        rendered_html.setAttribute("id","rendered_html");
        rendered_html.setAttribute("style","border: 1px solid #EB0D1B; width: 360px; font-family: courier; font-size: 100.5%; margin: 0px auto; border: 1px; text-align: center; margin-top: 5px;");
