$.ajax({ type: 'get/post', url: 'url', async: true, xhrFields: {withCredentials: true}, crossDomain: true }); // 原生js xhr.withCredentials = true; //withCredentials属性用于跨域请求中允许携带凭据信息
用HTML+CSS实现如下样式布局:

// jQuery isEmptyObject() function isEmptyObject(e) { var t; for (t in e) return !1; return !0; }
// 第二种 var obj = {}; if (JSON.stringify(obj) == '{}') return true;
// 单例模式 var singleton = function(fn) { var obj; return function() { console.log(this, arguments); return obj || (obj = fn.apply(this, arguments)); } } var createMask = singleton(function() { return document.body.appendChild(document.createElement('div')); }); console.log(createMask());
// 例二 var lis = document.querySelectorAll('ul.test li'); for (var i = 0; i < lis.length; i++) { lis[i].onclick = (function(ii) { return function() { console.log(ii); }; })(i); }
