Generally, we use the replace() function to replace the particular word phrase. This does not work for replacing all occurrences of a string. i.e replace() is replaces only first matching word phrase only.
For example "How to replace all occurrences of a string in JavaScript".
Here I want to replace the space with "-" 'in all occurrences. Now I use the replace().
Now my result is How-to replace all occurrences of a string in JavaScript
Here replace() is just replaces the word phrase only once. You have to replace all occurrences of a string. Use the custom function findAndReplace().
For example "How to replace all occurrences of a string in JavaScript".
Here I want to replace the space with "-" 'in all occurrences. Now I use the replace().
1 2 3 4 | var title = "How to replace all occurrences of a string in JavaScript";var result = title.replace(" ", "-");console.log(result);//How-to replace all occurrences of a string in JavaScript |
Here replace() is just replaces the word phrase only once. You have to replace all occurrences of a string. Use the custom function findAndReplace().
1 2 3 4 5 6 7 8 9 10 11 | function findAndReplace(string, target, replacement) { var i = 0, length = string.length; for (i; i < length; i++) { string = string.replace(target, replacement); } return string;}var title = "How to replace all occurrences of a string in JavaScript";var result = findAndReplace(title, " ", "-");console.log(result);//How-to-replace-all-occurrences-of-a-string-in-JavaScript |
