Question

<FRAMESET COLS="*,*" ONLOAD="selectFrames()" ONUNLOAD="alert('stopped')"

</FRAMESET>
<script language="javascript">

function selectFrames(){
base="frame/"
newFrames = new Array("red.htm","blue.htm","pink.htm","grey.htm")
window.firstFrame.location = base+newFrames[Math.round(5*Math.random())%5] 
window.secondFrame.location = base+newFrames[Math.round(5*Math.random())%5] 
}

Answer 1

<FRAMESET COLS="*,*" ONLOAD="selectFrames()" ONUNLOAD="alert('stopped')">
  <FRAME SRC = "frames/grey.htm" NAME="firstFrame">
  <FRAME SRC = "frames/blue.htm" NAME="secondFrame">
</FRAMESET>
<script>
function selectFrames(){
    var bs = "frames/",
    newFrames = ["red.htm","blue.htm","pink.htm","grey.htm"];
    window.frames['firstFrame'].location.href = bs + newFrames[Math.round(Math.random()*5)];
    window.frames['secondFrame'].location.href = bs + newFrames[Math.round(Math.random()*5)];
}
</script>

To keep track of syntax errors add this code in your head: 要跟踪语法错误，请在您的头上添加以下代码：

<head><script>
"use strict";
window.onerror = function(msg, url, line){
    alert(unescape(msg) + '\nFile: <a href="' + url + '">' + url + '</a>\nat Line: ' + line);
}
</script></head>

Answer 2

Your missing the closing bracket on your <FRAMESET tag: 您缺少<FRAMESET标签上的<FRAMESET括号：

<FRAMESET COLS="*,*" ONLOAD="selectFrames()" ONUNLOAD="alert('stopped')"

Should be: 应该：

<FRAMESET COLS="*,*" ONLOAD="selectFrames()" ONUNLOAD="alert('stopped')">

You're also missing semi-colons from the end of your lines in javascript. 您还会在javascript行尾缺少分号。
