I need to find a number from a string value like:
tag:example.com,1999:blog-124938250235712450.post-092348192357990021
I have used this method via JQuery:
JavaScript & HTML Code:
var getId = 'tag:example.com,1999:blog-124938250235712450.post-092348192357990021', postID = getId.match(/post-\\w*/), blogID = getId.match(/blog-\\w*/); /* Print Post ID */ $('#post-id').html(postID); /* Print Blog ID */ $('#blog-id').html(blogID);
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script> Getting Post ID : <span id='post-id'></span> <br/> Getting Blog ID : <span id='blog-id'></span>
So, the output for:
POST ID is like post-092348192357990021
BLOG ID is like blog-124938250235712450
.
But, I just need the digits for each one for example:
POST ID like this: 092348192357990021
BLOG ID like this: 124938250235712450
.
I hope you help me guys
Thanks in advance!
Use RegEx capture groups ()
and select the capture via it's index [1]
.
If you only need numbers you could also just capture the numbers with \\d
.
var getId = 'tag:example.com,1999:blog-124938250235712450.post-092348192357990021', postID = getId.match(/post-(\\d*)/), blogID = getId.match(/blog-(\\d*)/); /* Print Post ID */ $('#post-id').html(postID[1]); /* Print Blog ID */ $('#blog-id').html(blogID[1]);
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script> Getting Post ID : <span id='post-id'></span> <br/> Getting Blog ID : <span id='blog-id'></span>
If that's the exact format, you don't even need a regex.
var getId = 'tag:example.com,1999:blog-124938250235712450.post-092348192357990021'; var [postID, blogID] = getId.split(":blog-")[1].split(".post-"); /* Print Post ID */ $('#post-id').html(postID); /* Print Blog ID */ $('#blog-id').html(blogID);
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script> Getting Post ID : <span id='post-id'></span> <br/> Getting Blog ID : <span id='blog-id'></span>
Just use split and pop after you've converted your object to a String:
var getId = 'tag:example.com,1999:blog-124938250235712450.post-092348192357990021', postID = getId.match(/post-\\w*/).toString().split('-').pop(), blogID = getId.match(/blog-\\w*/).toString().split('-').pop(); /* Print Post ID */ $('#post-id').html(postID); /* Print Blog ID */ $('#blog-id').html(blogID);
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script> Getting Post ID : <span id='post-id'></span> <br/> Getting Blog ID : <span id='blog-id'></span>
