[英]Why isn't my onchange function working?
我是ruby的新手，尝试在此处调用js函数onchange，但无法正常工作且未获得合适的答案。
= 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')"
select方法参数为：
select（方法，选项=无，选项= {}，html_options = {}，＆block）
您已经针对html_options使用了options ，因此必须将代码替换为：
= 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 JS 函数在 html 表单中通过“onchange”调用时不起作用？
