How to Download an Excel File Generated from an MVC Form using AJAX?
Jan 29, 2025 am 12:15 AM
When processing large forms in MVC, a Excel file may need to be generated, which contains data from a specific subset of the form without affecting the rest. AJAX provides a solution by allowing you to send some requests to the server.
Can't download the Excel file directly
Unfortunately, you cannot return the files you want to download directly through AJAX. Instead, please explore the replacement method of using AJAX to publish related data to the server.
The generating and response of the server -side file
On your server, you can use the server code to generate excel files. For this reason, please consider using libraries such as Epplus or NPOI. You can pass the path or file name of the created file as the return value to your Ajax call. Reset to the file to download
In the client's JavaScript, you can use
to set the position of the JavaScript window to the URL of the file to indicate the browser to download it. Seamless user experience
window.location = '/Reports/Download?file=' returnValue
This method provides seamless user experience because the file download operation will not leave the source page.
The controller method used for file download
The corresponding controller method of the download operation may be shown below:

Yes, function overloading is a polymorphic form in C, specifically compile-time polymorphism. 1. Function overload allows multiple functions with the same name but different parameter lists. 2. The compiler decides which function to call at compile time based on the provided parameters. 3. Unlike runtime polymorphism, function overloading has no extra overhead at runtime, and is simple to implement but less flexible.

C has two main polymorphic types: compile-time polymorphism and run-time polymorphism. 1. Compilation-time polymorphism is implemented through function overloading and templates, providing high efficiency but may lead to code bloating. 2. Runtime polymorphism is implemented through virtual functions and inheritance, providing flexibility but performance overhead.

Yes, polymorphisms in C are very useful. 1) It provides flexibility to allow easy addition of new types; 2) promotes code reuse and reduces duplication; 3) simplifies maintenance, making the code easier to expand and adapt to changes. Despite performance and memory management challenges, its advantages are particularly significant in complex systems.

Polymorphisms in C are divided into runtime polymorphisms and compile-time polymorphisms. 1. Runtime polymorphism is implemented through virtual functions, allowing the correct method to be called dynamically at runtime. 2. Compilation-time polymorphism is implemented through function overloading and templates, providing higher performance and flexibility.

People who study Python transfer to C The most direct confusion is: Why can't you write like Python? Because C, although the syntax is more complex, provides underlying control capabilities and performance advantages. 1. In terms of syntax structure, C uses curly braces {} instead of indentation to organize code blocks, and variable types must be explicitly declared; 2. In terms of type system and memory management, C does not have an automatic garbage collection mechanism, and needs to manually manage memory and pay attention to releasing resources. RAII technology can assist resource management; 3. In functions and class definitions, C needs to explicitly access modifiers, constructors and destructors, and supports advanced functions such as operator overloading; 4. In terms of standard libraries, STL provides powerful containers and algorithms, but needs to adapt to generic programming ideas; 5
