In recent years, with the rapid development of mobile Internet, people's demand for mobile applications has become higher and higher. In order to meet the different needs of users, developers need to develop and publish applications on multiple platforms. In this case, cross-platform development technology is particularly important. As an efficient cross-platform development framework, UniApp has been favored by more and more developers.

However, you may encounter many minor problems in actual development. Among them, entering double quotes is a more difficult problem. In Vue, it is very common to use double quotes as quotes for attribute values, but they are also required in HTML. So, how to enter double quotes correctly in UniApp?

First of all, we need to understand the use of double quotes in HTML tags. In HTML, we can use double quotes or single quotes to represent attribute values. For example, we can write:

<input>

Note that the attribute value needs to be wrapped in double quotes or single quotes so that it can be parsed correctly. If you need to use double quotes in attribute values, you can use the escape character "\" to achieve this.

For example, in HTML, we can write like this:

<input>

Here we use " instead of double quotes. In this way, what is displayed on the page is "a car is named "benz"" .

Next, in UniApp, we need to perform similar operations to correctly enter double quotes. UniApp supports JavaScript syntax, so we can use character escapes in JavaScript to enter double quotes.

For example, in the Vue component, we can write like this:


<script>
export default {
  data() {
    return {
      car: &#39;a car is named "benz"&#39;
    }
  }
}
</script>

Here we use Vue's data binding syntax to bind the value of car to the value attribute of input. Note that in Vue There is no need to use escape characters to enter double quotes. Vue will automatically escape the entered double quotes.

In the JavaScript file in UniApp, we can use escape characters to enter double quotes. For example:

let car = 'a car is named "benz"';

In this way, we can correctly enter double quotes in UniApp. It should be noted that when there are multiple double quotes in the program, we need to maintain a unified input method. For example, in HTML we use Double quotes, in JavaScript we use escape characters to enter double quotes.

In summary, when entering double quotes in UniApp, you can use character escape in JavaScript, or you can use Vue's data binding Syntax is automatically escaped, and a unified input method must be maintained to avoid errors.

Finally, what needs to be reminded is that when writing code, you must pay attention to the correct coding style and write clear and easy-to-understand code. This not only It can reduce the possibility of errors and improve the readability and maintainability of the code, making development more efficient and code quality better.
