I have a textfield with the id "foo" that sometimes exists and sometimes not. If it exists I'd like to fill in a certain value.
How do you do this by using **RJS** (in *Rails 2.2*)?
I tried this and it doesn't work:
if page[:foo]
page[:foo].value = "bar"
end
I get
> TypeError: Null Value if the textfield doesn't exist
.
以上就是RJS: Check for existing page element?的详细内容，更多请关注web前端其它相关文章！
