我的阵列是:
var a = new Array();
a[0] = {x: 10,y: 10};
a[1] = {x: 20,y: 50};
a[2] = {x: 30,y: 20};
a[3] = {x: 10,y: 10};
var min = Math.min.apply(null, a.x)不起作用.一些想法？
(对不起我的英语不好)
我正在尝试我的第一个rails web应用程序.这是我的代码:
模型:
class Movie < ActiveRecord::Base
attr_accessible :about, :title, :url
end
控制器:
class MoviesController < ApplicationController
def show
@movie = Movie.find(params[:id])
end
def update
@mov = Movie.find(params[:id])
if @mov.update_attributes(params[:id])
redirect_to movies_path, :notice => "Your movie has been updated."
else
render "show"
end
end
def destroy
end
end
Run Code Online (Sandbox Code Playgroud)<%= form_for @movie do |m| %> <center> <table> <td valign='middle' align='right'> Title: </td> <td> <%= m.text_field :title %> </td> <tr> <td valign='middle' align='right'> Description: </td> <td> <%= m.text_area :about %> …
(抱歉我的英文= /) 这是伪的:
function lnko(a, b)
-if a = b then lnko := a
-if a < b then lnko := lnko(a, b-a)
-if a > b then lnko := lnko(a-b, b)
function end
我的代码是:
<html>
<head>
<script type="text/javascript">
function run()
{
var a = document.getElementById("a").value;
var b = document.getElementById("b").value;
var s = lnko(a,b)
document.write(a+"/"+b+"<br>"+(a/s)+"/"+(b/s));
// document.write("<br>"+s)
}
function lnko(a,b)
{
alert(a+"..."+b)
if (a==b)
{
return a;
}
if (a<b)
{
return lnko(a,(b-a));
}
if (a>b)
{
return lnko((a-b),b);
} …
