    你在笔下做事的方式有两个问题:

    1. 您将其中一个选项设置为“选定”。您只需将默认的“Select One”作为顶部选项,将其值设置为“”,而不将属性设置为“selected”,这样HTML“required”就可以检测到尚未选择任何内容。
    2. 您可以通过单击按钮进行处理(图形绘制和填充),而不是表单提交。因此,即使表单未正确提交,该过程也将运行。

    太长,读不下去了 你应该让所有的 <option> 未选中,并为无效选项提供值“”。 

    <select required name="" id="">
    <option value="" >Select One</option>
    ... other options
</select>

    您应该为表单提供“id”属性: 

    ...
<form id="myForm" action="">
...

    并且仅在表单提交时处理: 

    $("#myForm").on("submit", function(e) {
  // do your stuff here
  ...
}
