如何将参数传递给绑定方法？绑定与匿名方法 [英] How do I pass arguments to bound methods? bind vs. anonymous methods

问题描述

我尝试用下面带有参数的方法替换方法名称，但这不起作用。

I tried replacing the method name with a method w/ arguments below but this did not work.

// just a minimizer method

function m5(a,b)
  {
  return document.getElementById(a).onkeypress=b;
  }

// On page initialization thse methods are bound to text input boxes

m5('signin_pass',bind_enter_key(event,interface_signin));  // this does not work
m5('upload_file',bind_file_upload);

推荐答案

您可以使用匿名函数执行此操作用正确的参数调用你的函数：

You can do it like this with an anonymous function that calls your function with the correct parameters:

// just a minimizer method

function m5(a,b) {
  return document.getElementById(a).onkeypress=b;
}

// On page initialization these methods are bound to text input boxes

m5('signin_pass', function(event) {bind_enter_key(event,interface_signin)});  // this does not work
m5('upload_file', bind_file_upload);

这会创建一个匿名函数，该函数作为函数传递给m5，匿名函数调用你的函数适当的参数。

This creates an anonymous function which is passed to m5 as the function and that anonymous function calls your function with the appropriate parameters.
