The difference and solution between using v-html to render SVG in Vue and writing templates directly
In Vue.js projects, using the v-html directive and writing SVG code directly in templates sometimes creates rendering differences, especially when dealing with SVG elements. This article will analyze its causes and provide solutions.
Problem: v-html rendering SVG effect is abnormal
When writing a piece of HTML code containing SVG elements directly into the Vue template, the rendering effect is normal; however, the rendering effect is deviated by dynamically inserting the same code using the v-html instruction.
Cause: SVG attribute case sensitive
HTML attribute names are case-sensitive, but SVG attribute names are case-sensitive. v-html directive will strictly follow the SVG specification when parsing HTML, resulting in, for example, viewbox is recognized as an invalid attribute, and viewBox is the correct attribute name.
Solution: Fix SVG attribute case
The solution is simple: check whether there are case errors in the SVG code, such as changing viewbox to viewBox . When Vue processes v-html content, it will strictly parse attributes according to the SVG specification, so it is necessary to ensure that the attribute name is case correctly.
Specific steps:
- Check SVG code: Carefully check all attribute names in the SVG code, especially common attributes such as
viewBoxandfill. - Correct attribute name: Fix all case errors that do not comply with SVG specifications to correct case.
After ensuring that the SVG code complies with the SVG specification, the SVG effect rendered using v-html will be consistent with the effect written directly in the template. This can effectively avoid inconsistent problems when rendering v-html , and ensure the correct display of SVG elements in the application.

How to traverse arrays of vue arrays
Apr 08, 2025 am 06:39 AM
To iterate through the array in Vue.js, you can use the v-for directive. The syntax of this directive is <template v-for="item in items">, where item is the current element in the array and items is the array to be traversed. In addition, the v-for directive also provides the following other functions: v-for.of is used to specify the array to be traversed, v-for.in is used to specify the object properties to be traversed, v-for.index is used to obtain the array index currently traversed, and v-for.key is used to specify the unique key of each element to optimize list rendering.
How to use function intercept vue
Apr 08, 2025 am 06:51 AM
Function interception in Vue is a technique used to limit the number of times a function is called within a specified time period and prevent performance problems. The implementation method is: import the lodash library: import { debounce } from 'lodash'; Use the debounce function to create an intercept function: const debouncedFunction = debounce(() => { / Logical / }, 500); Call the intercept function, and the control function is called at most once in 500 milliseconds.
How to solve mysql cannot be started
Apr 08, 2025 pm 02:21 PM
There are many reasons why MySQL startup fails, and it can be diagnosed by checking the error log. Common causes include port conflicts (check port occupancy and modify configuration), permission issues (check service running user permissions), configuration file errors (check parameter settings), data directory corruption (restore data or rebuild table space), InnoDB table space issues (check ibdata1 files), plug-in loading failure (check error log). When solving problems, you should analyze them based on the error log, find the root cause of the problem, and develop the habit of backing up data regularly to prevent and solve problems.

Solutions to the errors reported by MySQL on a specific system version
Apr 08, 2025 am 11:54 AM
The solution to MySQL installation error is: 1. Carefully check the system environment to ensure that the MySQL dependency library requirements are met. Different operating systems and version requirements are different; 2. Carefully read the error message and take corresponding measures according to prompts (such as missing library files or insufficient permissions), such as installing dependencies or using sudo commands; 3. If necessary, try to install the source code and carefully check the compilation log, but this requires a certain amount of Linux knowledge and experience. The key to ultimately solving the problem is to carefully check the system environment and error information, and refer to the official documents.
