Sass variable default scope

江枫思渺然 提交于 2019-12-29 04:16:12
问题 I have a problem with using variable defaults in Sass across scopes. My test example is: @mixin foo { $val: 'red' !default; .bar { color: $val; } } @include foo; .class1 { $val: 'green'; @include foo; .class11 { @include foo; } } $val: 'black'; .class2 { @include foo; } .class3 { $val: 'blue'; @include foo; } .class4 { @include foo; } It is compiles to: .bar { color: "red"; } .class1 .bar { color: "red"; } .class1 .class11 .bar { color: "red"; } .class2 .bar { color: "black"; } .class3 .bar {

jQuery.extend()和jQuery.fn.extend()的用法和区别

1.jQuery.extend(object);为扩展jQuery类本身.为类添加新的方法。 2.jQuery.fn.extend(object);给jQuery对象添加方法。 jQuery.extend() 函数用于将一个或多个对象的内容合并到目标对象。 语法 $.extend( target [, object1 ] [, objectN ] ); 否深度合并 $.extend( [deep ], target, object1 [, objectN ] );//默认为false。如果该值为true,且多个对象的某个同名属性也都是对象,则该"属性对象"的属性也将进行合并(不支持第一个参数传递 false) 。 如果只为$.extend()指定了一个参数,则意味着参数target被省略。此时,target就是jQuery对象本身。通过这种方式,我们可以为全局对象jQuery添加新的函数。 如果多个对象具有相同的属性,则后者会覆盖前者的属性值 var object1 = { apple: 0, banana: {weight: 52, price: 100}, cherry: 97 }; var object2 = { banana: {price: 200}, durian: 100 }; /* object2 合并到 object1 中 */ $.extend(object1,

Vue中发送ajax请求——axios使用详解

我只是一个虾纸丫 提交于 2019-12-27 05:59:55
axios 基于 Promise 的 HTTP 请求客户端,可同时在浏览器和 node.js 中使用 功能特性 在浏览器中发送 XMLHttpRequests 请求 在 node.js 中发送 http 请求 支持 Promise API 拦截请求和响应 转换请求和响应数据 自动转换 JSON 数据 客户端支持保护安全免受 XSRF 攻击 浏览器支持 安装 使用 bower: $ bower install axios 使用 npm: $ npm install axios 例子 发送一个 GET 请求 // Make a request for a user with a given ID axios.get('/user?ID=12345') .then(function (response) { console.log(response); }) .catch(function (response) { console.log(response); }); // Optionally the request above could also be done as axios.get('/user', {params: {ID: 12345}}) .then(function (response) { console.log(response); }) .catch

Axios 中文说明 Axios 是一个基于 promise 的 HTTP 库,可以用在浏览器和 node.js 中。 Features 从浏览器中创建 XMLHttpRequests 从 node.js 创建 http 请求 支持 Promise API 拦截请求和响应 转换请求数据和响应数据 取消请求 自动转换 JSON 数据 客户端支持防御 XSRF <script src=" https://unpkg.com/axios/dist/axios.min.js"></script&gt ; Example 执行 GET 请求 // 为给定 ID 的 user 创建请求 axios.get('/user?ID=12345') .then(function (response) { console.log(response); }) .catch(function (error) { console.log(error); }); // 可选地,上面的请求可以这样做 axios.get('/user', { params: { ID: 12345 } }) .then(function (response) { console.log(response); }) .catch(function (error) { console.log(error); }); 执行 POST

Default permission/group data in Django

假如想象 提交于 2019-12-24 02:55:10
问题 Every time I wipe the database of my Django app during testing (or when cloning or deployin), I have to go into /admin and set up permissions and groups. Where would I put the code that would populate the DB with them and what would it look like? 回答1: For this you can use fixtures. For example: python manage.py dumpdata auth > fixtures/auth.json This will store all models of package 'auth' (Users, Groups Relations) into auth.json After Deployment you can use the following command to load:

ES6 - Object.assign()

倾然丶 夕夏残阳落幕 提交于 2019-12-23 15:32:15
ES6 - Object.assign() 语法与定义: Object.assign 方法用于对象的合并,将源对象(source)的所有可枚举属性,复制到目标对象(target)。 Object.assign 方法的第一个参数是目标对象,后面的参数都是源对象。 const target = { a : 1 } ; const source1 = { b : 2 } ; const source2 = { c : 3 } ; Object . assign ( target , source1 , source2 ) ; target // {a:1, b:2, c:3} 注意,如果目标对象与源对象有同名属性,或多个源对象有同名属性,则后面的属性会覆盖前面的属性。 const target = { a : 1 , b : 1 } ; const source1 = { b : 2 , c : 2 } ; const source2 = { c : 3 } ; Object . assign ( target , source1 , source2 ) ; target // {a:1, b:2, c:3} 如果只有一个参数,Object.assign会直接返回该参数。 const obj = { a : 1 } ; Object . assign ( obj ) === obj //

问题 If I build a 1.0 app with 2 strings in the defaults, using registerDefaults . And in a 2.0 version, I decide to remove the first old string, and move the second one (changing its key string) with a new third one into an array. How may I deal with this and how to deal with the changes that could have been made to the content through versions. 1.0 Prefs should be StringKey someValue DateKey 10/10/2010 1.1 Prefs should be StringKey someValue DateKey 2010/10/10 2.0 Prefs should be Array Item0 is

Default values for CMAKE_FIND_LIBRARY_PREFIXES/CMAKE_FIND_LIBRARY_SUFFIXES

问题 i guess i'm missing something very obvious here, but it seems to me that the cmake variables CMAKE_FIND_LIBRARY_PREFIXES/CMAKE_FIND_LIBRARY_SUFFIXES are not set to any "decent" default value depending on the current system/settings! i've checked the cmake docs and google, but there seems nothing about it really. for example, a simple CMakeLists.txt essentially calling find_package(OpenSSL REQUIRED) will break unless you set the variables in your main file or directly invoke cmake -DCMAKE_FIND
