How to remove labels from things printed in vue-Front-end Q&A-php.cn

In Vue, we often use {{ }} to present the data that needs to be displayed on the page. However, when we print out the response data in Vue, sometimes some HTML tags appear in the tags. So, in this article, we will explain how to remove these marks.

First of all, we need to know why HTML tags appear when printing response data in Vue. The reason for this is that the template syntax in Vue is based on HTML. When we use {{ }}, Vue will automatically fill the HTML tags with the data we want to display. For example:

<div>{{ message }}</div>

Copy after login

In the above example, Vue will fill the value of "message" into the

tag. If our "message" value is a string containing some HTML tags, then these tags will also be filled in the

tag.

In order to solve this problem, we can use the v-html directive provided in Vue. This directive allows us to render HTML markup directly in Vue. For example:

<div v-html="message"></div>

Copy after login

In the above example, Vue will directly render the value of "message" into an HTML tag and display it in the

tag. However, it should be noted that there are some security risks when using the v-html directive, because it allows users to inject malicious scripts or HTML tags. Therefore, safety measures must be taken when using the v-html directive.

Also, if we just want to display plain text instead of HTML markup, we can use an attribute called innerText. This attribute retrieves the plain text content of an element and ignores HTML tags within it. For example:

<div id="myDiv"><span>Hello</span> world!</div>

<script>
  const div = document.querySelector("#myDiv");
  console.log(div.innerText); // 输出 "Hello world!"
</script>

Copy after login

In the above example, we first define a

tag with some HTML tags and set an ID value to it. Then, in JavaScript, we use querySelector to get the

tag, and use the innerText attribute to get its plain text content, and print it to the console.

In summary, we can remove HTML tags in response data in Vue through the v-html directive or innerText attribute. However, pay attention to security when using the v-html directive to ensure that users are not allowed to inject malicious scripts or HTML tags.
