好吧，这就是一切，但我的问题很小.. 页面已设置，点系统正确，我需要做的就是让输入显示与点系统匹配并显示与之关联的警报。
问题是当用户在文本框中输入命令时，它应该提醒等级是什么(专业人士、新手、初学者、菜鸟)
<HTML>
<HEAD>
<script>
function system(){
var point=document.world.system.txt_points.value
var tourn=document.world.system.txt_tourn.value
var level=document.world.system.txt_level.value
var check=document.world.system.txt_check.value
var results=document.world.system.txt_results.value
if ((point>=100000)&&(level>10)&&(tourn>25))
{
results=alert("pro status")
}
if((points>=100000)&&(level>10))
{
alert("Novice")
}
if (point>=100000)
{
alert("beginner")
}
if (points<100000)
{
alert("noob")
}
if (check=true)
{
alert("pro")
}
}

最佳答案
您的 HTML 中充满了无效标记。我已经对其进行了一些清理(它仍然存在问题)，并向表单添加了一个 onsubmit 来调用您的系统函数。我也修改了你的系统功能。您并不总是使用正确的名称来引用变量。 (用点代替点等)。下次，在发布问题或代码之前进行一些拼写检查。一般来说，一两个错别字被认为只是被忽略了，但你的错别字有很多。只要你花几分钟仔细查看一下，你就会更接近开始。
