statics are the methods defined on the Model. methods are defined on the document (instance). We may also define our own custom document instance methods too. // define a schema var animalSchema = new Schema({ name: String, type: String }); // assign…
没有发现普通都语法错误,然后一一比对官方教程里面的代码,发现是在“@bp.route('/<int:id>/delete', methods=('POST'))”这一行代码里面methods的赋值有问题,要求是一个可迭代对象;但是现在的methods并不是一个元祖.所以要在mehtods赋值的第一个元素后面跟随一个逗号,即更改为"@bp.route('/<int:id>/delete', methods=('POST',))",然后就运行成功了. 谨记:只有一个…

计算属性:Vue.js 模板内的表达式非常便利,但是缺点就是只能用于简单的运算,如果模板中有太多的逻辑运算会让模板不堪重负且难以维护.恰恰计算属性可以处理复杂的逻辑运算,也就是说对于任何复杂逻辑你都应当使用计算属性. 1.计算属性基础列子 <!DOCTYPE html> <html> <head lang="en"> <meta charset="UTF-8"> <title></title>…

一.methods中参数的传递 使用方法和正常的javascript传递参数的方法一样,分为两部: 1.在methods的方法中进行声明,比如我们给add方法加上一个num参数,就要写出add:function(num){}. 2.调用方法时直接传递,比如我们要传递2这个参数,我们在button上就直接可以写.<button @click=”add(2)”></button>. 现在知道了加参数的方法,看一段完整的代码,代码中给add添加了num参数,并在按钮上调用传递了.   &…

1. computed(计算属性) 计算属性的结果会被缓存,除非依赖的响应式属性变化才会重新计算.注意,如果某个依赖 (比如非响应式属性) 在该实例范畴之外,则计算属性是不会被更新的. eg: <p>computed={{sum}}</p> computed: { sum: function () { console.log('这是cpmputed实现的a+b处理') return Number(this.a) + Number(this.b) } } 注意:当页面多次调用sum,…
一.computed的本质? computed为什么不像methods一样加小括号使用? 正常使用computed方式 运行结果 至于为什么computed为什么不像methods一样使用小括号调用,是由于computed本身就是一个属性,其本质是computed内部有两个方法(set和get),computed最终的道德的结果是get方法的返回值,而set方法很少使用到,因此简化写法就是上述正常使用computed的格式,其本质写法如下展示. <!DOCTYPE html> <html…
