label动态加减变更效果

showPollMoney(num) {//默认状态，一般在onload（）调用
this.poolMoney.string = num;//poolMoney是要动态显示的label，
var len = this.poolMoney.string.length
if (len < 14) {
var str = this.poolMoney.string
for (var i = 0; i < 14 - len; i++) {//默认14位0
str = "0" + str;
}
}
this.poolMoney.string = str;
},
//***每次改变值时调用，jackpot是传入的最终值
showJackpot(jackpot) {
var str_jackpot = this.poolMoney.string;
var cur_jackpot = parseInt(str_jackpot);
var interval =10;//根据效果调整累加值
this.jackpotAction = cc.repeatForever(cc.sequence(cc.delayTime(0.01), cc.callFunc(function () {
cur_jackpot = cur_jackpot + interval;
if (cur_jackpot > jackpot) {
cur_jackpot = jackpot;
this.poolMoney.node.stopAllActions();
}
var str = "";
for (var j = 0; j < 14 - ("" + cur_jackpot).length; ++j) {
str = str + "0";
}
this.poolMoney.string = str + cur_jackpot;
}.bind(this))));
this.poolMoney.node.runAction(this.jackpotAction);
},
//比如断线后设置原来的值时调用
setPoolMoney(money) {
var times = 20;
