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

Devexpress 笔记

GridView显示行号

Private Sub GridView1_CustomDrawRowIndicator(sender As Object, e As DevExpress.XtraGrid.Views.Grid.RowIndicatorCustomDrawEventArgs) Handles GridView1.CustomDrawRowIndicator
     e.Info.DisplayText = e.RowHandle.ToString()
End Sub

 

CSS 笔记

引用外部CSS。注意是 href，不是src。

<link href=”img/divcss5.css” rel=”stylesheet” type=”text/css” />

float属性似乎对div更有效

<html>
    <head>
        <title>标题</title>
        <style type="text/css">
            body{
                padding:0px;
                margin:0px;
            }
            .container{
                position:relative;
                width:950px;
                margin-left:auto;
                margin-right:auto;
                height:100%;
                background-color:#FF0000;
            }
            .left{
                float:left;
                background-color:#DDD;
                width:80%;
                height:100px;
            }
            .right{
                float:right;
                background-color:#AAA;
                width:20%;
                height:100px;
            }
        </style>
    </head>
    <body>
        <div class="container">
            <div class="left">左边</div>
            <div class="right">右边</div>
        </div>
</body>
</html>
