自封装Jsonp完美解决冲突

// 完美解决并发冲突

var Jsonp = { setJsonp: function(option) { var succenn_name = "g_" + new Date().getTime() + Math.floor(Math.random() * 8999 + 1000); var html = document.getElementsByTagName('html')[0]; var scriptDOM = document.createElement('script'); scriptDOM.type = "text/javascript"; console.log(option.url + (option.url.indexOf('?') != -1 ? '&' : '?') + "jsoncallback=Jsonp." + succenn_name); scriptDOM.setAttribute('src', encodeURI(option.url + (option.url.indexOf('?') != -1 ? '&' : '?') + "jsoncallback=Jsonp." + succenn_name)); html.appendChild(scriptDOM); html.removeChild(scriptDOM); this[succenn_name] = function(res) { this.func(res) delete this.that[this.name] }.bind({ that: this, name: succenn_name, func: option.success }); } } // 调用 Jsonp.setJsonp({ url: 'url', success: function(res) { } });
