问题描述
我在我的应用程序中使用提示,他们非常乐于助人。
I use jQuery Impromptu prompts in my application and they're very helpful.
但是,要调用Impromptu提示,您需要指定按钮名称及其返回值,如下所示:
However to call the Impromptu prompts you need to specify the button names and their return values like so:
$.prompt('Example 2',{ buttons: { Ok: true, Cancel: false } });
我真的想拥有动态按钮名称,如下所示:
I would really like to have dynamic button names, something like this:
function showprompt(question, button1, button2) {
$.prompt(question,{ buttons: { button1: true, button2: false } });
}
但这似乎不起作用,按钮只叫'button1 '和'button2'!
But this doesn't seem to work, the buttons are just called 'button1' and 'button2'!
我尝试过使用 eval(button1)
和 ''+ button1
但它们会带来语法错误。
I've tried using eval(button1)
and ''+button1
but they bring up syntax errors.
有什么建议吗?
推荐答案
由于对象文字中的属性名称可以是标识符(而不是字符串),因此不能为它们使用变量。
Since property names in an object literal can be identifiers (rather than strings), you can't use a variable for them.
你必须创建对象,然后使用方括号表示法来赋值。
You have to create the object, and then use square bracket notation to assign the values.
function showprompt(question, button1, button2) {
var buttons = { };
buttons[button1] = true;
buttons[button2] = false;
$.prompt(question,{ buttons: buttons });
}
