Question

我是ruby的新手并试图在这里调用js函数onchange但是没有工作而没有得到合适的答案。

= f.select :amendment_type, [['Renewal','renewal'],['Lease Amendment Agreement','Lease Amendment Agreement'],['Expansion','Expansion'],['Storage','Storage'],['Parking','Parking'],['Other(for me to fill in)','Other']], class: "amendment_type input", style: "width: 450px;", onchange: "alert('hello')"

Answer 1

select方法参数为：

select（method，choices = nil，options = {}，html_options = {}，＆amp; block）

您已针对options使用html_options，因此您必须将代码替换为：

= f.select :amendment_type, [['Renewal','renewal'],['Lease Amendment Agreement','Lease Amendment Agreement'],['Expansion','Expansion'],['Storage','Storage'],['Parking','Parking'],['Other(for me to fill in)','Other']], {}, class: "amendment_type input", style: "width: 450px;", onchange: "alert('hello')"

为什么我的onchange功能不起作用？
