Question

<form  action="/custAction" formName="cust-100">

i tried below

self.opener.document.$('[name="formName"]').val() but it gives error

TypeError: self.opener.document.$ is not a function

Answer 1

您没有用于窗体控制的val（），请尝试使用html（）函数。

val = $(window.parent.document).find('form').attr("formName");
