Vue error: Unable to correctly use v-html to render HTML code, how to solve it?

Vue is a popular JavaScript framework that can help us build interactive user interfaces. In Vue, we can use the v-html directive to render HTML code into templates. However, sometimes we may encounter a problem: the HTML code cannot be rendered correctly using v-html. This article will describe some common causes and solutions to help you solve this problem.

1. The first possible reason is that the Vue dependency is not introduced correctly. Before using Vue, we need to introduce Vue's source code into the project or introduce Vue through CDN. Please make sure that Vue has been correctly introduced into your project and the version is compatible with your code.
2. The second reason is that your HTML code contains disallowed tags or attributes. Vue by default uses the browser's innerHTML property to render HTML code into the template. However, some browsers restrict the use of certain tags or attributes, such as the

In this example, we store the HTML code in the html variable in the data attribute and compile the HTML code into Executable functions. The compiled HTML code is then rendered into the template through the v-html directive.

3. The third possible reason is using incorrect syntax. In Vue, the v-html directive is used by adding the v-html attribute on the element where the HTML code is to be rendered, and using the HTML code as the value of the attribute. Make sure you are using the correct syntax and passing the HTML code as a string to the v-html directive. Here is an example:

In this example, we directly pass the HTML code as a string to the v-html directive.

To sum up, when you cannot use v-html to render HTML code correctly, first make sure that Vue's dependencies have been introduced correctly. Secondly, please check whether your HTML code contains disallowed tags or attributes. If so, try to compile the HTML code using Vue's compiler options. Finally, make sure you use the correct syntax and pass the HTML code as a string to the v-html directive. With the above method, you should be able to successfully solve the problem of not being able to render HTML code correctly using v-html.
