javascript怎么传参数

window["name"] = "the window object";

window.localStorage.setItem("name", "xiaoyueyue"); window.localStorage.getItem("name");

var obj = { type: undefined, text: "xiaoyueyue", methord: function() { alert("I am an methord"); } }; localStorage.setItem("data", JSON.stringify(obj)); console.log(JSON.parse(localStorage.getItem("data"))); // {text: "xiaoyueyue"}

function parseParam(url) { var paramArr = decodeURI(url) .split("?")[1] .split("&"), obj = {}; for (var i = 0; i < paramArr.length; i++) { var item = paramArr[i]; if (item.indexOf("=") != -1) { var tmp = item.split("="); obj[tmp[0]] = tmp[1]; } else { obj[item] = true; } } return obj; }

function GetQueryString(name) { var reg = new RegExp("(^|&)" + name + "=([^&]*)(&|$)"); var r = window.location.search.substr(1).match(reg); if (r != null) return unescape(r[2]); return null; }

var box = document.createElement("p"); box.innerHTML = "点击"; document.body.appendChild(box); // name,age,friend function alertInfo(data) { alert( "大家好,我是" + data.name + ", 我今年" + data.age + "岁了，我的好朋友是" + data.friend + " !" ); }

var getIndexByClass = function (param) { var element = param.classname ? param : param.target; var className = element.classname; var domArr = Array.prototype.slice.call(document.querySelectorAll('.' + className)); for (var index = 0; index < domArr.length; index++) { if (domArr[index] === element) { return index; } } return -1; },

点击

var btn = document.querySelector("button"); btn.onclick = function() { alert(this.dataset.name); };

var name = "xiaoyueyue", age = 25; var box = document.createElement("p"); box.innerHTML = "点击"; document.body.appendChild(box); // name, age function alertInfo(name, age, home, friend) { alert("我是" + name); }

var name = 'xiaoyueyue', age = '25', home = 'shanxi', friend = 'heizi', DQ = """; // 双引号的超文本标记语言 var params = """ + name + "","" + age + "","" + home + "","" + friend + """; var params2 = DQ + name + DQ + ',' + DQ + age + DQ + ',' + DQ + home + DQ + ',' + DQ + friend + DQ; var box = document.createElement("p"); box.innerHTML = "点击"; console.log(box) document.body.appendChild(box); // name, age,home,friend function alertInfo(name, age, home, friend) { alert("我是" + name + ',' + "我今年" + age + "岁了！")

var data = [ { name: "xiaoyueyue", age: "25", home: "shanxi", friend: "heizi" } ]; var box = document.createElement("p"), html = ""; for (var i = 0; i < data.length; i++) { html += "点击"; } box.innerHTML = html; document.body.appendChild(box); function alertInfo(id, name, age, home, friend) { alert("我是 " + name + " , " + friend + " 是我的好朋友"); }

 分配 

function fenpei() { var args = Array.prototype.slice.call(arguments); alert("我是" + args[2] + "油品，数量为 " + args[1] + " 吨， id为 " + args[0]); }
