富文本中的文字一个个出现

不用富文本的方式用label实现打印，这种方法更加简便
onLoad:function () {
this.typingAni(this.text1,this.text1.string,function () {
this.text1.node.destroy();
}.bind(this),false)
var callback = function() {
this.typingAni(this.text2,this.text2.string,null,false);
}
this.scheduleOnce(callback, 10);
},
typingAni: function (label, text, cb,isclick) {
this.isclick = isclick;
var self = this;
var html = '';
var arr = text.split('');
var len = arr.length;
var step = 0;
self.func = function () {
if(this.isclick == true){
label.string = text;
return;
}
html += arr[step];
label.string = html;
if (++step == len) {
self.unschedule(self.func, self);
cb && cb();
}
}
self.schedule(self.func,0.1, cc.macro.REPEAT_FOREVER, 0)
},
onButton:function (btn,value) {
if(value == 1){
cc.director.loadScene("addScore");
}
else if(value == 2){
this.isclick = true;
}
},
