我无法以ng-style(shape.radius || shape.length)读取对象的属性。我现在甚至无法上班,但是想要包含或声明。与我的ng-class相似。
有一个生成形状的按钮,形状是随机大小创建的。这是我的代码:
HTML:
var app = angular.module('app', []);
app.controller('ShapeController', function(){
var vm = this;
vm.shapes = [];
vm.randomShapes = [];
vm.width = 30;
function createCircle(radius) {
let circle = new Circle(radius);
vm.shapes.push(circle);
} // end createCircle
function createSquare(length) {
let square = new Square(length);
vm.shapes.push(square);
} // end createSquare
vm.generateShapes = function() {
let times = 50
for (let i = 0; i < times; i++) {
createCircle(getRandomNumber());
}
for (let i = 0; i < times; i++) {
createSquare(getRandomNumber());
}
sort(vm.shapes);
console.log(vm.shapes);
}; // end generateShapes
}); // end controller
function sort(arr) {
arr.sort(function(a,b){
return b.getArea() - a.getArea();
});
} // end sort function
function getRandomNumber() {
return Math.random() * (100-1) + 1;
}
脚本:
{{1}}

width
应该在px
(某些单位,如em
,pt
等)或%
ng-style="{'width': shape.length + 'px'}"
