rjs中的确认对话框

Question

我的rjs模板中有以下代码，显示一个确认框：

page << "r = confirm('Would you like to link this newly created author to the book?')"

我试过

`page << "if r == true {"`   
 #do action a
`page << "} else {"`  
 #do action b
`page << "}"`

上面的代码不正确。

我的问题是如何获得确认框中的选择值（真或假）？

非常感谢提前。

Answer 1

尝试使用以下语法：

page << "var r = confirm('Would you like to link this newly created author to the book?');"

page << "if (r == true) {" 
  #do action a
page << "} else {"
  #do action b
page << "}"

我试过了，似乎有效。
