Vue realizes electronic quotation form for single-head multi-body

Efficient corporate management is inseparable from electronic quotation forms. This article will explain how to use Vue.js to build a complex electronic quotation form with single header and multiple table bodies, and ensure the accuracy of data calculations and the unmodification of logic.

Requirements Analysis

A typical quotation form contains one header and multiple bodies, each with a different product or service. The row data of each table body must be automatically calculated based on the preset factory logic and summarized to the table body unit price. Unlike Excel, this electronic form does not allow users to modify the calculation logic at will.

Vue.js solution

We use Vue.js and table components to implement this function. Editable cells are directly edited using contenteditable="true" attribute, and the calculation logic is encapsulated inside the Vue component to ensure the accuracy of data calculations and the immutability of logic.

Specific steps:

1. Table structure: using Vue component

   Tags render the entire form, For headers, multiple Correspond to different manifestations.

   Editable cell: Add contenteditable="true" attribute to the cell that needs to be entered by the user, allowing direct editing.

   Automatic calculation and summary: Use Vue's computational properties ( computed ) or methods ( methods ) to achieve calculation and summary of suggested prices. Every time a user modifies the cell content, Vue will automatically recalculate and update the data.

   Logic protection: The calculation logic is completely encapsulated inside the Vue component. Users can only enter data through editable cells and cannot directly modify the calculation formula to ensure data integrity and consistency.

   Through the above steps, a single-table multi-body electronic quotation form with complete functions and logical security can be built in Vue.js. While meeting user editing needs, it can ensure the accuracy of data calculations and the immutability of logic.
