现在我的问题是document.getElementById('sub').submit();无效
如何使此表单正常工作？
答案 0 :(得分：2)
#sub是您的提交按钮。您想提交表单，所以：
document.getElementById("form1").submit();
另外，既然它是表单的一部分，它应该有一个'form'属性，所以你可以这样做：
document.getElementById("sub").form.submit();
答案 1 :(得分：0)
您正在尝试提交一个按钮，您应该尝试提交表单。
或者使用JS单击“提交”按钮。
所以：
document.getElementById('form1').submit();
或者：
document.getElementById('sub').click();
答案 2 :(得分：0)
您提交表单元素，而不是按钮元素。
为表单指定一个id - 例如“associateform”，然后将您的javascript更改为：
document.getElementById('associateform').submit();
另一种方法是： http://www.javascript-coder.com/javascript-form/javascript-form-submit.phtml
答案 3 :(得分：0)
页面中有两种形式，请检查这是否有效
document.forms [0] .submit（）;
或
document.forms [1] .submit（）;
