如何在没有括号的情况下调用函数时传递参数[Javascript]
问题描述：
我有一个名为tryMe的函数，我在没有括号的情况下调用它并不是这样，但这个想法就像你在这里做的那样：
I have a function called "tryMe" and I'm calling it without the parenthesis not precisely this but the idea is like what you would do here:
setTimeout(tryMe,200);
如何传递我需要的参数？
how can I pass parameters that I need?
我正在使用一个jquery插件，它允许我调用一个函数，但我必须用括号调用它，或者它在加载时自行执行。
I am using a jquery plugin that enables me to call a function but I have to call it withou the parenthesis or it executes itself upon loading.
答
setTimeout(function() { tryMe(parm1, parm2); }, 200);
更强大的产品，确保 parm1的值， parm2 在超时发生之前不要更改（@ lincolnk的评论）：
A more robust offering, to ensure that the values of parm1, parm2 don't change before the timeout fires (per @lincolnk's comment):
setTimeout(function() {
var p1 = parm1;
var p2 = parm2;
tryMe(p1, p2);
}, 200);
@patrick dw，你是对的，必须先评价。
@patrick dw, you're right, has to be evaluated before.
