How to introduce ActiveX in Vue

Preface

Vue is a popular framework in front-end development. It allows us to quickly build reusable components and improve development efficiency. But sometimes, we may encounter some problems when using Vue. For example, this article will talk about: how to introduce ActiveX in Vue and use its methods.

Problem Description

During the Vue project development process, we may need to use ActiveX controls and use some of the methods it provides to complete our needs. But, in Vue, how can we introduce an ActiveX control and call its methods?

Solution

1. Introducing ActiveX controls into Vue

Introducing ActiveX controls into Vue is very simple, just use it in the component Just introduce the <object> tag. For example, if we want to introduce the Microsoft Excel control, we can write it like this:

<object id="objExcel" name="objExcel" classid="clsid:00024500-0000-0000-C000-000000000046" width="0" height="0"></object>

Among them, the classid attribute value is the unique identifier of the control in the registry.

2. Call ActiveX control method in Vue

The method of calling ActiveX control in Vue is also very simple. You only need to get the control object first, and then use the method to fulfill our needs. Taking Excel table data as an example, we can achieve it through the following code:

var objExcel = document.getElementById("objExcel");
var objWorkbook = objExcel.Workbooks.Open("Test.xlsx");
var objWorksheet = objWorkbook.Worksheets("Sheet1");
var objRange = objWorksheet.Range("A1:B3");
var arrData = objRange.Value;

In the above code, we obtain the objExcel object and then call its Workbooks, Worksheets, Range and other attributes finally obtained the data in the Excel table.

Notes

You need to pay attention to the following points when using ActiveX controls:

• First of all, you have to make sure that the control you are using has been installed on the client machine on, otherwise an error will be thrown when calling the control.
• Secondly, since third-party controls are used, the security level of the IE browser needs to be set on the client machine to allow the ActiveX control to run before it can be used normally.
• Finally, since this method requires operation on the client, the Excel program needs to be installed on the client machine, otherwise the Excel control cannot be used.

Conclusion

It is feasible to introduce ActiveX into Vue and use the methods it provides to complete some tasks, but it requires corresponding configuration and installation on the client machine. Pay attention to safety issues. In future development, we can choose whether to use ActiveX controls according to specific needs, and configure accordingly according to the client environment.
