// array表示要遍历的数组,obj表示遍历时的每个元素,index表示遍历数组的下标,当然ng中提供 ng-repeat指令也是可以循环遍历angular.forEach(array,funciton(obj,index){// dosomething} React中: react中父组件向子组件传值,同样,使用最多是map方法 Vue中 vue中比较粗暴,直接用指令v-for="item in items"可以遍历...
filter(); filter() 方法创建一个新的数组,新数组中的元素是通过检查指定数组中符合条件的所有元素。(返回数组,包含了符合条件的所有元素。如果没有符合条件的元素则返回空数组。) 注意:filter() 不会改变原始数组。 注意:filter() 不会对空数组进行检测。 vararr = [1,2,3,4,5,6,7]varnewArr = arr.f...
find()只返回第一个满足条件的元素,如果需要所有满足条件的元素,应该使用Array.prototype.filter()。 如果数组中没有元素满足条件,find()会返回undefined。 解决问题的示例 如果你在使用find()方法时遇到了问题,比如没有返回预期的结果,可能的原因包括:

For any other files, it will end up doing a bit more work, but its worth remembering that the heuristics will filter out most files anyway. One thought I did have is adjusting those heuristics to look for template: rather than Component (or maybe look for both). If you are testing a ...
