Highlight text vue

Something that always seems to come up in my development is the need to find character combinations within a string and render those characters in a special way to the end user. Earlier inI wrote an article titled, Highlight Text Within a String Using Angular and Regular Expressionswhich focused on highlighting text in a string using the very popular Angular framework.

Using regular expressions, the text was replaced with an HTML-wrapped equivalent to give it a nice highlighting effect. Angular isn't the only web framework on the internet. There are other popular frameworks that work in a similar fashion but are still very different. We're going to see how to highlight text within a string using the very popular Vue.

The query variable will represent our user input and be bound to form input, and the content variable represents some lorem ipsum to be searched and highlighted. For this example, we have a single function called highlight. When called, the query variable will be checked to see if it is empty.

If it is empty, the original content variable will be returned. If it is not empty, we do a string replace. We search the content for the query and return the match wrapped in some HTML with a class that looks like this:. So how do we make use of this in the HTML that is actually rendered to the screen? Instead, we have to use:. The v-html in the above line will render any HTML that appears in our string.

This means that any matches to our regular expression will be highlighted yellow. You just saw how to make use of regular expressions within a Vue. This is very similar to an Angular variation that I had written about previously. Knowing how and when to use regular expressions is a great skill to have, even in JavaScript development.

You can even define option groups with the options prop:. Manually placed options and option groups will appear below the options generated via the options prop.

To place manual options and option groups above the options specified by the options prop, use the named slot first. Available fields:. Avoid using complex types in values. If both html and text are provided, html will take precedence.

Note that not all browsers will render inline html i. Be cautious of placing user supplied content in the html field, as it may make you vulnerable to XSS attacksif you do not first sanitize the user supplied string.

If an array entry is a string, it will be used for both the generated value and text fields. You can mix using strings and objects in the array. Internally, BootstrapVue will convert the above array to the following array the array of objects format:. If value is missing, then text will be used as both the value and text fields.

Internally, BootstrapVue will convert the above object to the following array the array of objects format:. Note: When using the Object format, the order of the final array is not guaranteed.

You can use the select-size prop to switch the custom select into a select list-box, rather than a dropdown.

Note when select-size is set to a value greater than 1, the Bootstrap v4 custom styling will not be applied, unless the multiple prop is also set. Enable multiple select mode by setting the prop multipleand control how many rows are displayed in the multiple select list-box by setting select-size to the number of rows to display.
