1.定义 栈:后进先出(LIFO-last in first out):最后插入的元素最先出来. 队列:先进先出(FIFO-first in first out):最先插入的元素最先出来. 2.用数组实现栈和队列 实现栈: 由于数组大小未知,如果每次插入元素都扩展一次数据(每次扩展都意味着构建一个新数组,然后把旧数组复制给新数组),那么性能消耗相当严重. 这里使用贪心算法,数组每次被填满后,加入下一个元素时,把数组拓展成现有数组的两倍大小. 每次移除元素时,检测数组空余空间有多少.当数组里的元素
在使用queryselector获取一个dom元素,编译时却报错说property 'style' does not exist on type 'element'. 原因:这是typescript的类型检查导致的,需要在querySelector方法前面加个类型断言. let frameContainObj = document.getElementById("model_view_container") let iframeObj= <HTMLElement>frame
使用vue-cli 3.0+Element-ui时候,调用form表单校验时候出现的问题是: Property 'validate' does not exist on type 'Element | Element[] | Vue | Vue[]'. Property 'validate' does not exist on type 'Element'. 解决方案 (this.$refs.form as any).validate((valid: boolean) => { if (vali
