In modern business environments, electronic quotation forms are crucial, which can significantly improve efficiency and accuracy. This article will explain in detail how to use the Vue.js framework to build complex quotation forms with single headers and multiple table bodies, and realize automatic calculation and summary functions.
Requirements Analysis
The goal is to create a quote form with one header and multiple bodies. Each table body is a table whose row data calculates the recommended price based on the preset business logic and is automatically summarized to the total price of the table body. Unlike Excel, users cannot directly modify calculation formulas.
Implementation plan
We adopt the componentized development model of Vue.js, combine v-for
instructions to render tables dynamically, and use computational properties and methods to achieve automatic calculation and summary.
Data structure: Use an array to store the data of each table body. Each array element is an object that contains all rows of data of the table body.
Table rendering: Use Vue.js' template syntax to render the table header and table body.
v-for
instruction traverses the data array and dynamically generates each table body and its row. Consider using a custom component to encapsulate each watch body to improve code reusability.-
Recommended price calculation: define a function
calculateSuggestedPrice(item)
inmethods
of the Vue component to calculate the recommended price of each row based on the preset business logic. The parameteritem
of this function represents the data object of the current row.methods: { calculateSuggestedPrice(item) { // Calculate the suggested price based on actual business logic, for example: return item.quantity * item.unitPrice; } }
-
Automatic summary: Use the computed attribute
computed
to calculate the total price of each body and the total of all body in real time.computed: { tableTotals() { return this.tableData.map(table => ({ total: table.reduce((sum, item) => sum this.calculateSuggestedPrice(item), 0) })); }, grandTotal() { return this.tableTotals.reduce((sum, table) => sum table.total, 0); } }
User input limit: In order to prevent users from modifying the calculation logic, the calculation logic can be completely encapsulated inside the Vue component, allowing the user to enter only the original data (such as quantity, unit price, etc.). You can use
v-model
to bind data and add input verification as needed.
Through the above steps, a fully functional single-table multi-body electronic quotation form can be built in Vue.js to realize automatic calculation and summary, and effectively prevent users from misoperating or maliciously modifying calculation formulas. To enhance the user experience, consider adding data verification, form verification, and a more granular UI design.

To develop a complete Python Web application, follow these steps: 1. Choose the appropriate framework, such as Django or Flask. 2. Integrate databases and use ORMs such as SQLAlchemy. 3. Design the front-end and use Vue or React. 4. Perform the test, use pytest or unittest. 5. Deploy applications, use Docker and platforms such as Heroku or AWS. Through these steps, powerful and efficient web applications can be built.

The garbled problem in Java Chinese is mainly caused by inconsistent character encoding. The repair method includes ensuring the consistency of the system encoding and correctly handling encoding conversion. 1.Use UTF-8 encoding uniformly from files to databases and programs. 2. Clearly specify the encoding when reading the file, such as using BufferedReader and InputStreamReader. 3. Set the database character set, such as MySQL using the ALTERDATABASE statement. 4. Set Content-Type to text/html;charset=UTF-8 in HTTP requests and responses. 5. Pay attention to encoding consistency, conversion and debugging skills to ensure the correct processing of data.

Whether it’s low-cost pre-sale coins that offer a lot of upside, or a blue chip network that prepares for critical upgrades, this moment provides a unique entry point. From fast scalability to flexible modular blockchain architecture, these four outstanding names have attracted attention throughout the market. Analysts and early adopters are watching closely, calling them the best crypto coins to buy short-term gains and long-term value now. 1. BlockDag (BDAG): 7 days left

Linux system restricts user resources through the ulimit command to prevent excessive use of resources. 1.ulimit is a built-in shell command that can limit the number of file descriptors (-n), memory size (-v), thread count (-u), etc., which are divided into soft limit (current effective value) and hard limit (maximum upper limit). 2. Use the ulimit command directly for temporary modification, such as ulimit-n2048, but it is only valid for the current session. 3. For permanent effect, you need to modify /etc/security/limits.conf and PAM configuration files, and add sessionrequiredpam_limits.so. 4. The systemd service needs to set Lim in the unit file

Custom Laravel user authentication logic can be implemented through the following steps: 1. Add additional verification conditions when logging in, such as mailbox verification. 2. Create a custom Guard class and expand the authentication process. Custom authentication logic requires a deep understanding of Laravel's authentication system and pay attention to security, performance and maintenance.

ServiceWorker implements offline caching by intercepting network requests and providing pre-cache resources. The specific steps include: 1) Register ServiceWorker and check browser support; 2) Define cache policies and pre-cache resources in the sw.js file; 3) Pre-cache resources using install event and decide to obtain resources from the cache or network in the fetch event; 4) Pay attention to version control, cache policy selection and debugging skills; 5) Optimize cache size, process dynamic content, and ensure that scripts are loaded through HTTPS.
