This article mainly introduces the console.log print result is [object Object] how to solve the related knowledge, the content is detailed and easy to understand, the operation is simple and fast, has a certain reference value, I believe that after reading this console.log print result is [object Object] how to solve the article will be harvested, let's take a look at it.

console.log print result is [object Object] problem

Before using + to connect, such as: console.log ("front parameter param is: "+self.filters.ip)

The result is: [Object Object]

solutions

In a VUE file, the original data of the print splice is separated by, such as

console.log ("front-end param yes: ", self.filters.ip)

The results are displayed normally:

Object and object[object]

In the process of doing the project, I accidentally found that the result obtained by using object[object] and object.object is the same, which makes me feel very surprised. After all, object[object] was used in arrays before, and has not been used like this.

Case const lineChartData = { newVisitis: { expectedData: ['2020-12- 1','2020-12- 2','2020-12- 3','2020-12- 4','2020 -12- 5','2020-12- 6','2020-12- 7'], //Daily enrollment date actualData: [120, 82, 91, 154, 162, 140, 145] //Daily signups}, messages: { expectedData: [200, 192, 120, 144, 160, 130, 140], actualData: [180, 160, 151, 106, 145, 150, 130] }, purchases: { expectedData: [80, 100, 121, 104, 105, 90, 100], actualData: [120, 90, 100, 138, 142, 130, 130] }, shoppings: { expectedData: [130, 140, 141, 142, 145, 150, 160], actualData: [120, 82, 91, 154, 162, 140, 130] }}

As above, if we use objects inside newVisitis, then we must get them through this.lineChartData.newVisitis.

But at this time we can also get it through **this.lineChartData[newVisitis]**

The code is as follows:

methods: { handleSetLineChartData(type) { console.log(type) console.log( lineChartData[type]," lineChartData[purchases]") console.log( lineChartData.purchases," lineChartData.purchases") this.lineChartData = lineChartData[type] } }

The results were as follows:
