Http post 常用的四种请求方式

阅读更多关于 Http post 常用的四种请求方式

http1.1协议规定http 的请求方式有OPTIONS、GET、HEAD、POST、PUT、DELETE、TRACE、CONNECT几种方式。其中POST是一种最常用的向服务器提交数据的方法，本文主要讨论POST提交数据的四种方式。 application/x-www-form-urlencoded 这应该是最常见的 POST 提交数据的方式了。浏览器的原生 <form> 表单，如果不设置 enctype 属性，那么最终就会以 application/x-www-form-urlencoded 方式提交数据。请求类似于下面这样（无关的请求头在本文中都省略掉了）： POST http://www.example.com HTTP/1.1 Content-Type: application/x-www-form-urlencoded;charset=utf-8 title=test&sub%5B%5D=1&sub%5B%5D=2&sub%5B%5D=3 首先，Content-Type 被指定为 application/x-www-form-urlencoded；其次，提交的数据按照 key1=val1&key2=val2 的方式进行编码，key 和 val 都进行了 URL 转码。大部分服务端语言都对这种方式有很好的支持。例如 PHP 中，$_POST['title']

AngualrJs: do I require $scope in my controller for this?

阅读更多关于 AngualrJs: do I require $scope in my controller for this?

问题 I am trying to emulate this Plunker, specifically adding a button to each row of an ag-grid. function ageClicked(age) { window.alert("Age clicked: " + age); } function ageCellRendererFunc(params) { params.$scope.ageClicked = ageClicked; return '<button ng-click="ageClicked(data.age)">Age</button>'; } Ag-grid calls ageCellRendererFunc to render the cell. It is generating some HTML to ender a button, which, when clicked will cause ageClicked to be called. That params.$scope.ageClicked =

Dynamically generating validation attribute on input using interpolation

阅读更多关于 Dynamically generating validation attribute on input using interpolation

问题 Edit: This question is no longer relevant as of Angular version: 1.3.0-beta.12 you can now parse ng-minlength and ng-maxlength dynamic values. See: https://github.com/angular/angular.js/issues/5319 My problem is quite simple: I need to dynamically create input validation (ex. ng-minlength ) using interpolation. And doing that I am running into some issues specifically generating the validation attributes for ng-minlength and ng-maxlength . I assume this is due to them only taking constants?

The best way to remove duplicate strings in an array

阅读更多关于 The best way to remove duplicate strings in an array

问题 We have managed to create the script below to remove any duplicate strings from an array. However, it is important that we keep the order of the array for when angular loops through them on an ng-repeat. In addition, we want the remaining elements to keep the same index. scope.feedback = _.map(_.pluck(item.possibleAnswers, 'feedback'), function (element, index, collection) { return collection.slice(0, index).indexOf(element) === -1 ? element : ''; }); This code above works however we feel

阅读更多关于 Why do Angular (1.5) components always have an isolated scope?

问题 I'm building an Angular library that provides a bunch of components that should make it easier to build SPA application on top of a certain API. For some components we're using the multi-slot transclusions feature. Multi-slot transclusions and components were introduces in the AngularJS 1.5 release. I really like both features, but I don't understand why components always have an isolated scope. I would like to control how variables are accessible in my transcluded template. But now I can't,
