While going through the VueJS Filter(orderby) API documentation, I came across some confusion regarding the arguments. Below is a sample for reference:
Arguments:
{String | Function} targetStringOrFunction
"in" (optional delimiter)
{String} [...searchKeys]
I would appreciate any help or clarification on this. Thank you!
According to the information provided in the Documentation, it is mentioned that the filter filterBy is specifically designed for directives that require Array values, such as v-for.
As for the arguments:
If you have an array of strings and wish to filter it based on a value from an input field, you can achieve this by utilizing filterBy in the following manner:
new Vue({
el: '...',
data: {
searchedValue: '' // Leaving it empty will display all results
}
...
});
In the HTML:
<div v-for="value in values | filterBy searchedValue">
You can connect the searchedValue to an input field for added functionality.
Refer to the example below for using functions.
in and {String} [...searchKeys] arguments :If you have an array of users, with properties like firstName and lastName, and want to filter them based on a specific value, you can employ filterBy as shown below:
<div v-for="user in users | filterBy searchedValue in 'firstName'">
Alternatively, you can search through multiple keys:
<div v-for="user in users | filterBy searchedValue in 'firstName' 'lastName'">
Additionally, you can create a function to encapsulate your code like this:
var demo = new Vue({
el: '#demo',
data: {
searchedValue: '',
users: [
{firstName: 'John', lastName:'Doe'},
{firstName: 'David', lastName:'Bazz'},
{firstName: 'Peter', lastName:'Foo'},
]
},
methods: {
myFilter: function(user) {
return user.firstName == searchedValue; //Or any other condition you prefer
}
},
})
I hope that helps :)
