我是这个网站的新手，需要帮助。
我有一些朋友（不再联系）为我制作的代码。我的目标是在代码中添加一些复选框，以便所选项目将显示在整个输出中。 这是我现有的代码。
<!-- the script to read the options and make the code -->
<script>
function makeTemplate(){ var newcode="";
for (i=0; i<document.source.elements.length; i++){
newcode=newcode+document.source.elements[i].value;
}
document.getElementById('outputview').innerHTML=newcode;
document.getElementById('outcode').value=newcode;
}
</script>
<!-- end of script -->
<!--
Notice that quotes inside descriptive elements are not allowed.
Use the 7-character code "&rdquo;" instead in the option list values.

Please double check your volt, current and connector requirements. <br>
On a side note, if you do match all three but
the form factor (what it looks like) is different,
this may still work for you.<br>

<br><input type=submit value="MAKE" onclick="makeTemplate()">

所以，我想做的是在代码中添加一些复选框，如果在表单上检查，它们将显示在页面底部的输出中。像这样...
（复选框）一些文字
（复选框）其他一些文字
（复选框）第三个选项
所以，如果我检查第一个和第三个复选框，＆＃34;一些文字＆＃34;和＃34;第三种选择＆＃34;将显示在屏幕底部的两个输出中，但不显示在中间的一些＆＃34;其他一些文本＆＃34;
我希望这是有道理的。
