Vue Js Get Substring before a specific Character:In Vue.js, you can use the built-in slice method to get a substring before a specific character. First, you need to find the index of the character using the indexOf method. Then you can use the slice method to get the substring from the start of the string to the index of the characte

What is the best way to get the substring before a specific character in Vue.js?

his code creates a Vue instance and defines its data properties: originalString and substring. The originalString is set to ‘Font-Awesome’, and the substring is an empty string initially.

In the created() lifecycle hook, the code finds the index of the first occurrence of the - character in the originalString using the indexOf() method. If the - character is found, the code extracts the substring from the start of the originalString to the character just before the - using the substring() method, and assigns it to the substring data property.

So, after the created() hook runs, the substring data property will contain the substring of originalString before the first occurrence of the - character. In this case, substring will be ‘Font’

Vue Js Get Substring Before A Specific Character Example

<script type="module" >
    const app = new Vue({
    el: "#app",
    data() {
        return {
            originalString: 'Font-Awesome',
            substring: ''
        }
    },
    created() {
        const index = this.originalString.indexOf('-');
        this.substring = this.originalString.substring(0, index);
    }
});
</script>

What is the syntax or code snippet that can be used to retrieve the substring before the first occurrence of a dash in a string that contains two dashes?

If the original string has two dashes and you want to get the substring before the first dash, you can still use the indexOf() and substring() methods as follows:

<script type="module" >
    const app = new Vue({
    el: "#app",
    data() {
        return {
            originalString: 'Hello-World-2023',
            substring: ''
        }
    },
    created() {
        const index = this.originalString.indexOf('-');
        this.substring = this.originalString.substring(0, index);
    }
});
</script>

If you want to get both substrings separated by the dash, you can modify the code to use the split() method instead of the substring() method. Here’s an example

<script type="module" >
    const app = new Vue({
    el: "#app",
    data() {
        return {
            originalString: 'Hello-World-2023',
            firstSubstring: '',
            secondSubstring: ''
        }
    },
    created() {
        const substrings = this.originalString.split('-');
        this.firstSubstring = substrings[0];
        this.secondSubstring = substrings[1];
    }
});
</script>
