Filters are a functionality provided by Vue components that let you apply formatting and transformations to any part of your template dynamic data. The filter property of the component is an object. A single filter is a function that accepts a value and returns another value. The returned value is the one that’s actually printed in the Vue.js template. To check string is palindrome or not using filters, we have to first reverse the string and accordingly write the logic of string palindrome and apply the filter on the string. Both the example is working on different approach.
Example 1:
index.html
<!DOCTYPE html> <html lang="en"> <head> <script src= </script> </head> <body> <div id='parent'> <p> <strong>String1 : </strong> {{ st1 | pCheck }} </p> <p> <strong>String2 : </strong> {{ st2 | pCheck }} </p> </div> <script src='app.js'></script> </body> </html> |
app.js
const parent = new Vue({ el : '#parent', data : { st1 : 'I am not', st2 : 'iTopiNonAvevAnoNipoTi', }, filters:{ pCheck : function(data){ var rev = []; for (let i = data.length - 1, j = 0; i >= 0; i--, j++) rev[j] = data[i]; reverse = rev.join(''); if(data == reverse) return 'Palindrome' else return 'Not Palindrome' } } }) |
Output:
Example 2:
index.html
<!DOCTYPE html> <html lang="en"> <head> <script src= </script> </head> <body> <div id='parent'> <p> <strong>String1 : </strong> {{ st1 | pCheck }} </p> <p> <strong>String2 : </strong> {{ st2 | pCheck }} </p> </div> <script src='app.js'></script> </body> </html> |
app.js
const parent = new Vue({ el : '#parent', data : { st1 : 'I am not', st2 : 'iTopiNonAvevAnoNipoTi', }, filters:{ pCheck : function(data){ const reverse = data.split("").reverse().join(""); if(data == reverse) return 'Palindrome' else return 'Not Palindrome' } } }) |
Output:
