Acrobat XI 自动关闭

出处：http://tieba.baidu.com/p/6487351444?red_tag=i1920764958

Win10系统

方案一

左下角菜单打开后搜索“防火墙和系统保护”→找到并点击“高级设置”→点击“出站规则”→点击“新建规则”→要创建的规则类型“程序”，下一步→此程序路径，默认路径是“C:\Program Files (x86)\Adobe\Reader 11.0\Reader\AcroRd32.exe”，建议点击“浏览”，自己去去找到Adobe Reader安装目录下AcroRd32这个程序，下一步→“阻止连接”，下一步→何时应用该规则，全选，下一步→自己取个名称，例如“Adobe ReaderXI阻止出站连接”，完成。
然后再试试打开PDF文件是否5-10秒退出，我自己的完美解决~供参考

 

断网有用感谢！估计是官方后台连接搞得鬼！我用的方法是： 开始-控制面板-系统和安全-Windows防火墙-高级设置-出站规则-新建规则-程序-下一步-此程序路径-下一步-阻止连接-何时应用该规则 ？（全选）-下一步-自定义一个名称-完成。重启！ （我搞了半天才搞定，希望大家也有用

方案二

在C:\Windows\System32\drivers\etc\hosts 文件里添加项
127.0.0.1 acroipm.adobe.com       #阻止adobe reader的网问题解决

composer 笔记

Composer (on Windows) – Either the ‘extension_dir’ value is incorrect or the dll does not exist.

  1. 复制 php.ini-development 文件并重命名为 php.ini
  2. 去掉 extension=php_openssl.dll 前的;号（约880~900行处）
  3. 去掉 extension_dir = “ext”前的;号（约800行处）

数据库连接字符串 ConnectionString

laravel 笔记

1、blade 模板，模型关联为空值时，如何传值？

根据 $product->brand的值，显示对应名称

product.blade.php

productitem.blade.php

2、目录权限

在安装 Laravel 后，你可能需要配置一些权限。 storage 和 bootstrap/cache 目录在你的 web 服务下应该是可写的权限，否则 Laravel 将无法运行。如果你用的是 Homestead 虚拟机，这些权限应该已经设置好了。

3、php 安装 fileInfo扩展

4、提示“The Mix manifest does not exist.”

参考：https://xueyuanjun.com/post/19944.html

检查 public目录下是否有mix-manifest.json 文件，没有的话，通过以下步骤生成

1）检查 node，npm是否正确安装。
2）运行 npm install，Windows系统运行 npm install --no-bin-links
3）运行 Mix，npm run production

Thinkphp 文件上传

1、路由

Route::rule('fileUpload/:dir','index/FileUpload/index');

2、页面主要内容

 $('#exampleModal').on('show.bs.modal', function (event) {
            var button = $(event.relatedTarget)
            var imgpath = button.data('imgpath')

                </center>
            </div>

            <div class="modal-footer">

                <h6 class="info">info</h6>
            </div>
        </div>
    </div>
</div>

3、后台

<?php
namespace app\index\controller;

use think\Controller;
use think\Request;
use think\File;

use app\index\model\ProductModel;
use app\index\model\ExtraProductModel;

class FileUploadController extends Controller
{
    public function index($dir){        
        $id=request()->param('productid');
        $refresh=request()->param('refresh');

        $result;
      
        if($refresh==1){
            $product=ProductModel::where('id', $id)->find();
            $images=$product->images;
            
            $result['status']=1;
            $result['images']=$images;       
        }else{
            $file =request()->file('image');
        // 移动到框架应用根目录/public/uploads/ 目录下
             if($file){
            $info = $file->move(UPLOAD_PATH.$dir);
            if($info){               
                $extraProduct =new ExtraProductModel();
                $extraProduct->name=$info->getFilename();
                $extraProduct->file_path='/upload/'.$dir.'/'.$info->getSaveName();
                $extraProduct->product_id=$id;
                $extraProduct->save();
               
                $product=ProductModel::where('id', $id)->find();
                $images=$product->images;
                
                $result['status']=1;
                $result['images']=$images;                
            }else{
                $result['status']=0;
            }
        }else{
            $result['status']=0;
        }
    }
        return $result;
    }
}

 

Bootstrap 笔记

1、移动端手势滑动事件

$(function () {
        // 获取手指在轮播图元素上的一个滑动方向（左右）

        // 获取界面上轮播图容器
        var $carousels = $('.carousel');
        var startX,endX;
        // 在滑动的一定范围内，才切换图片
        var offset = 50;
        // 注册滑动事件
        $carousels.on('touchstart',function (e) {
            // console.log(e);
            // 手指触摸开始时记录一下手指所在的坐标x
            startX = e.originalEvent.touches[0].clientX;

        });
        $carousels.on('touchmove',function (e) {
            // 目的是：记录手指离开屏幕一瞬间的位置 ，用move事件重复赋值
            endX = e.originalEvent.touches[0].clientX;
        });
        $carousels.on('touchend',function (e) {
            //console.log(endX);
            //结束触摸一瞬间记录手指最后所在坐标x的位置 endX
            //比较endX与startX的大小，并获取每次运动的距离，当距离大于一定值时认为是有方向的变化
            var distance = Math.abs(startX - endX);
            if (distance > offset){
                //说明有方向的变化
                //根据获得的方向 判断是上一张还是下一张出现
                $(this).carousel(startX >endX ? 'next':'prev');
            }
        })
    });

2、去除 ul li 间的间隔

ul{
    list-style-type: none;
    margin:0px;
    padding:0px;
}
