微信小程序movable-view，bindchange、ani

问题：在使用movable-view时，bindchange改变时，启用的animation，导致初始化不能赋值
决绝: 赋值时animation为false，bindchange时animation为true（你可以试试直接设置animation为false,死机思密达）

index.js

Page({

  /**
   * 页面的初始数据
   */
  data: {
    _x: 0,
    number: 0,
    isAnimation: false //animation设置为false
  },
  /**
   * 生命周期函数--监听页面加载
   */
  onLoad: function (options) {
    this.setData({
      _x: 100
    })
  },
  onChange: function(e) {
    //bindchange时，animation设置为true
    this.data._x = e.detail.x
    this.data.number = this.accurate2hundredth(e.detail.x/275)
    this.setData({
      isAnimation: true,
      _x: this.data._x,
      number: this.data.number
    })
  },
  accurate2hundredth: function (num) {
    console.log(num)
    var p = num.toString().indexOf('.');
    var r = 0;
    if (p > 0) {
      r = ('' + num).substring(0, p + 3);
    }
    else {
      r = num + '.00';
    }
    let number =  r*100
    if(number>100){
      number = 100
    }
    return Math.round(number);
  }
})
