innerHTML示例运行良好，直到我将它们合并到其他Javascript中
javascript php html forms
innerHTML示例运行良好，直到我将它们合并到其他Javascript中,javascript,php,html,forms,innerhtml,Javascript,Php,Html,Forms,Innerhtml,我成功地尝试了使用innerHTML的示例，例如我的目标是在调用“onclick”时向JavaScript代码读写表单控件显示的值但是，当我简单地将一个示例放在现有PHP脚本的适当位置时，当我单击“Try It”按钮时，网页上不会显示任何内容。当然，现有代码有自己的表单、其他Javascript函数和对$\u POST值的引用这里是我的PHP脚本的一个摘录，包括示例“唐老鸭”代码。注意，调用myFunction（）和myFunction2（）时都不会产生任何屏幕更改。也没有使用docume

但是，当我简单地将一个示例放在现有PHP脚本的适当位置时，当我单击“Try It”按钮时，网页上不会显示任何内容。当然，现有代码有自己的表单、其他Javascript函数和对$\u POST值的引用
这里是我的PHP脚本的一个摘录，包括示例“唐老鸭”代码。注意，调用myFunction（）和myFunction2（）时都不会产生任何屏幕更改。也没有使用document.write（x）的版本

...
函数myFunction（）{
var x=document.getElementById（“rmOne”）；
var txt=“”；
var i；
对于（i=0；i”；
}
document.getElementById（“demo”）.innerHTML=txt；
}
函数myFunction2（）{
$\u POST.forEach（输出）
}
函数输出（元素、索引、数组）{
document.write（索引+元素+“
”）
}

单击“尝试”按钮以显示表单中第一个元素的值
试试看


...
函数myFunction（）{
var x=document.getElementById（“rmOne”）；
var txt=“”；
var i；
对于（i=0；i”；
}
document.getElementById（“demo”）.innerHTML=txt；

您无法访问JavaScript中的PHP变量，因为JavaScript get在客户端执行，而PHP get在服务器上执行
但是，您可以将PHP变量打印到JavaScript中，如下所示：
var myVar = <?php echo $yourPhpVariable; ?>;

var myVar=；
超时。我试图在网页上打开两张表格。只改变一个改变了反应的性质。现在，try-it click尝试错误地转到“action”链接（后续网页）（它还不存在，也不是用于该单击的链接。请继续关注。
更近一些，但还没有，尽管包含了一些建议。JavaScript myFunction（），据说称为“onclick”，仍然对显示的页面没有影响（和最初引用的例子一样：）。我修改了我的php代码，使其能够自己运行（没有$u POST依赖项，也没有MySQL访问——所有这些数据都是内部定义的），这样任何人都可以运行，所以请尝试

请注意，这一问题仍未解决：建议已被合并，但W3Schools示例代码，即使使用上述建议进行修改，也能自行工作，但当该代码集成到我的（修订过的）应用程序代码中时，调用的Javascript函数{myFunction（）}开头的警报（）不会发生（单击“试用”时）。当然，页面上随后的数据读取或写入也不会发生。下面是我的代码的切碎版本，这意味着所有原始MySQL代码都被删除，而生成的数据被直接编码到数组或常量值中，只是为了让这成为我可以共享的演示。调试代码也被切碎。请参考上面的W3Schools引文，然后尝试下面的方法。我显然需要帮助
