这是我的代码，它在while.Index超出绑定异常时显示错误。子字符串应该是这样的
- 每个字符串最多50个字符
- 不应该打破任何号码 - 例如“4318,4466,486”是可以接受的但是“4318,4466,48”不是
- 子字符串应始终以一个空格开头，并以逗号“，”
结尾
有人可以帮我解决这个问题

我在你的代码中做了一些修改。
$(document).ready(function(){
$.ajax({
url: 'http://finance.google.com/finance/info?client=ig&q=AMD',
dataType: 'jsonp',
data: { get_param: 'l' },
success: function(json) {
console.log(json);
}
});

while(!(output.charAt(end-1)==','))
{
end--;
}
将其更改为
while(!(output.charAt(end-1)==','))
{
if(end>=1)
end--;
else
break;
}
您不会收到错误，但您可能想要更改其他部分。 此外，您没有具体询问，但请查看此链接。
