1、 Change the value in the array 

paraList: [
	{
    txt:'123',chose:false},
	{
    txt:'1234',chose:false}
]

let choseChange = "paraList[" + index + "].chose"
this.setData({
    
	[choseChange]: true
})

Be careful ： The string of the selected array does not need to be written this.data. !!!

You can change the value of a specific subscript in the array

2、 Change the value in the object 

navbarData: {
    
    isfixed: false,
    iswhite: false, //icon color
    showCapsule: 1, // Whether to display the icon in the upper left corner  1 Presentation display  0 Means not to show 
    title: ' Customer list ', // The navigation bar   Middle title 
    backgroundcolor: '#fff',
    isintercept: false, // Back to intercept 
},

let title = 'navbarData.title'
this.setData({
    
	[title]: ' Team member customer ',
})
