1.1、缩略标记
//定义对象 //var car = new Object(); //car.colour = ‘red‘; //car.wheels = 4; //car.hubcaps = ‘spinning‘; //car.age = 4; //上述代码的简洁写法： var car = { colour: ‘red‘, wheels: 4, hubcaps: ‘spinning‘, age: 4 } //定义数组 var testArr = new Array(‘str1‘, ‘str2‘, ‘str3‘, ‘str4‘); //上述代码的简洁写法： var testArr = [‘str1‘, ‘str2‘, ‘str3‘, ‘str4‘]; //关联数组 var car = new Array(); car[‘colour‘] = ‘red‘; car[‘wheels‘] = 4; car[‘hubcaps‘] = ‘spinning‘; car[‘age‘] = 4;
//三重标记法
var direction;
if(x<200){ direction=1;}else{direction=-1}
//用三重标记法可写为
var direction=x<200?1:-1;
1.2、JSON数据格式
JSON是Javascript Object Notion的缩写
//描述乐队
var band = {
"name": "The Red Hot Chili Peppers",
"members": [
{
"name": "zhangsan",
"role": "lead vocals"
}, {
"name": "lisi",
"role": "bass guitar,trumpet,backing vocals"
}
],
"year":"2009"
}
