contidional orderBy only on init AngularJS

阅读更多关于 contidional orderBy only on init AngularJS

问题 How can I run orderBy filter only once when my view is initialized? I don't want my list to be reordered during runtime. <li ng-repeat="service in quote.services | orderBy:'index'" ></li> 回答1: Use the orderBy as a filter in your controller instead: app.controller('DemoCtrl', ['$scope', '$filter', function($scope, $filter){ $scope.quote.services = $filter('orderBy')($scope.quote.services, 'index'); }]); See the filter docs for all the options. 来源： https://stackoverflow.com/questions/35615976

问题 I am implementing ng-repeat to create elements for a bootstrap accordion interface. I have ng-repeat working however the issue I have is that I need to dynamically create the ID in order to target the accordion element individually.

问题 I have an ng-repeat that iterates through the names of countries in my model. On certain country names I want them abbreviated to reduce the length of the string, for example, I want 'Northern Ireland' to be outputted as 'N. Ireland'. JSON Model [ { "id": 1, "name": "Italy", }, { "id": 2, "name": "Northern Ireland", }, { "id": 3, "name": "Poland", } ] I could just change the name in my model, but I'd rather leave that as it is as the I want the raw data to be complete. It is only in this

Referencing a Nested Javascript Object dynamically

阅读更多关于 Referencing a Nested Javascript Object dynamically

问题 I have an array of objects ( $scope.fields ) that define how input fields should be set up for the $scope.data object model. The fieldName property is actually the path in the data Object to the field. Nested objects are separated by a period mark. eg: $scope.data = { user: { } } $scope.fields = [ {fieldName:'user.firstName',fieldLabel:'First Name',dsiabled:false} {fieldName:'user.location.lat',fieldLabel:'Latitude',dsiabled:false} {fieldName:'user.location.long',fieldLabel:'Latitude'

一丶页面中的指令　　1.ng-if=“” 指令可根据true或者false来决定显示不现实该标签体内容　　2.ng-repeat 当循环的集合中的元素为map对象时,应当书写为 (key,value) in “angular变量集合名” 　　3.ng-true-value="1" ng-false-value="0" 一般用于复选框，选中值为1否则为0 ，搭配ng-model=“”使用，可将其复制0或1 　　4.ng-options=“item.id as item.name for item in list”性可以在表达式中使用数组或对象来自动生成一个select中的option列表。ng-options与ng-repeat很相似，很多时候可以用ng-repeat来代替ng-options。　　　　但是ng-options提供了一些好处，例如减少内存提高速度，以及提供选择框的选项来让用户选择。一般用于select中　　5.ng-bind-html指令用于显示html内容例如：<div class="attr" ng-bind-html="item.title | trustHtml"></div> ，搭配$sce服务，写出的过滤器trustHtml进行使用　　6. ng-checked=“” 指令控制复选框的勾选状态

AngularJS: Make isolate scope directive template bind to parent scope

阅读更多关于 AngularJS: Make isolate scope directive template bind to parent scope

问题 I've been struggling with Angular's isolate scope for over 24hrs now. Here's my scenario: I have an ng-repeat iterating over an array of objects from which I want to use a custom directive to either generate a <select> or <input> based on the field_type property of the current object being iterated. This means I'll have to generate the template and $compile in the post-link function of the directive since I have no access to the iterated object in the template function. Everything works as

angular ng-repeat expressions as variables

阅读更多关于 angular ng-repeat expressions as variables

问题 I'm trying to do something like this: <ul> <li ng-repeat="{{myRepeatExpression}}">{{row.name}}</li> </ul> But because the ng-repeat logic is in the compile state of the directive it treats the {{myRepeatExpression}} as a normal string instead of a variable. Which doesn't work, obviously. Is there any workaround for that? 回答1: You can only use and expression with ng-repeat and not an interpolated value. Now in order to create a dynamic repeatable list you can try either: using a function that
