在setInterval中使用setData({})报错Invalid string length?Use setData(()) in setInterval to report Invalid string length?

//代码在onReady下let wxThis = this;let interval = setInterval(function() {      wxThis.setData({        test: 1      });      // if (wxThis.data.playerInfo.lifeTime > 15) {      //   clearInterval(interval);      // }    }, 600)

Framework type problem type API / component name terminal type wechat version basic library version applet bug setinterval tool 7.0.17 2.8.1 use SetData ({}) in setinterval to report invalid string length; at setTimeout callback function rangeerror: invalid string length test shows that setinterval and SetData can be used alone. //Under onready, let wxthis = this; let interval = setinterval (function()){ wxThis.setData ({ test: 1 }); // if ( wxThis.data.playerInfo . lifetime > 15) {/ / clearinterval (interval); / /}}, 600)

回答：

// 这段代码是在onReady下的this.run(ctx, width, height)this.gameLoop(ctx, width, height)​// 上述报错的那段代码是在this.run()下面，this.gameLoop也有一个setInterval,里面代码很多我就不贴上了//我尝试注释掉this.gameLoop还是报错
