详见github，使用方法参考index.html
function EventQueue(delayTime) {
this._delayTime = delayTime || 20;
this._queue = [];
}
EventQueue.prototype = {
add: function (excute, params) {
this._queue.push({
excute: excute,
params: params
});
this.start();
},
start: function () {
if (this._delayTime <= 0) {
this.process();
} else {
var self = this;
setTimeout(function () {
self.process();
}, self._delayTime);
}
},
process: function () {
var item = this._queue.shift();
if (item) {
var self = this;
item.excute(item.params, function () {
self.process();
});
}
}
};
