Answer 1

这是 页面 一个 大的 FRAME 套了两个小Frame 
左边的是 frame[0] 右边的是frame[1]我想实现 在 onload 查一次数据库的表usersong 时  调用 playinitinit（） 然后向playinit里传一个参数 i。把相应的 songname songurl songid singer 添加到 arr这个array里...
反正报错了...求解 不胜感激

}
window.onload=playinitinit;// JavaScript Document
代码 又 改了一下  总之 在function playerinit(i)
{
//歌曲列表
var id=<%=test.onload.getid(%>i<%)%>;
var name1=<%=test.onload.getsongname(%>i<%)%>;
var url=<%=test.onload.geturl(%>i<%)%>;
var singer1=<%=test.onload.getsinger(%>i<%)%>;
arr[i]=[id,name1,url,singer1]; document.getElementById("p3").innerHTML =name+"<br/>"+singer;

player.url=arr[id][2];
document.getElementById("play1").style.display="none";
document.getElementById("pause1").style.display="block";
player.settings.autoStart=true;
temptimer=setInterval('showtime()',1000);
alert(id);}
这儿嵌套上jsp语句时 下面的js语句就报错了，注释一下这句报错的，下面一句又跟着出错了..

Answer 3

确实啊，你找个调试工具,跟踪一下，查看一下变量的值，很好找到是哪个地方出错了的！程序是活的东西，代码是死的东西，直接看代码，还是不好定位的，推荐使用ff 的firebug来调试。

Answer 4

把你的关键地方贴出来，搞这么多没有用的代码，让人看了也怕怕的。把你的问题说清楚下，具体是什么问题。var id=<%=test.onload.getid(%>i<%)%>;
    var name1=<%=test.onload.getsongname(%>i<%)%>;
    var url=<%=test.onload.geturl(%>i<%)%>;
    var singer1=<%=test.onload.getsinger(%>i<%)%>;这种写法肯定是不行的，jsp页面在加载时就已经编译成html格式的了，在后面再调用这个函数根本得不到值的，除非是加载时初始化数据。好好看看jsp工作的原理吧。

Answer 5

我就是想 把数据库里的东西 传到js里面的。因为没学过ajax所以网上搜索时有人说var id=<%=test.onload.getid(%>i<%)%>;
    var name1=<%=test.onload.getsongname(%>i<%)%>;
    var url=<%=test.onload.geturl(%>i<%)%>;
    var singer1=<%=test.onload.getsinger(%>i<%)%>;
可以这样写 。现在搞明白了 得用ajax 或者jquery
