我在Firefox中测试我的问题。我点击保存按钮（这是一个输入，类型为button），它应该执行：输入按钮onclick在JSP中不起作用
onclick="checkchar()"
，但事实并非如此。
我在jsp部分代码：
<script language="javascript">
function checkchar(){
/*
if(document.Form2.stationRun.value.length>2500){
alert("站点运行情况字数不能超过2500字");
return;
}
if(document.Form2.devRun.value.length>2500){
alert("设备运行情况字数不能超过2500字");
return;
}
*/
//alert('before...');
document.Form2.action="${pageContext.request.contextPath}/system/elecCommonMsgAction_save.do";
document.Form2.submit();
alert(" 待办事宜保存成功!");
}
...
<input type="button" name="BT_Submit" value="保存" onclick="checkchar()" id="BT_Submit" style="font-size:12px; color:black; height:20px;width:50px">
我不知道为什么我点击我的保存按钮，该法并没有执行，一些人可以帮我吗？如果是由上传样式表（http://localhost:8080/css/Font.css）引起的？我不确定。
编辑
由于主框架是frameset，以及JavaScript方法和输入按钮是在我的主网页（你可以看到下面的，这是红色的长方形我想补充）。因此，使用萤火虫它显示那里不包含任何JavaScript代码。

并不重要，在页面的年底建成时，代码只声明功能 – charlietfl
@Mostafa Sabeghi我没有张贴的所有脚本方法在我的文章中，所以我没有复制结束脚本标记。 – 244boy
@charlietfl是的，你是对的 –
