JavaScript:
var data='<div id="hai">this is div</div>';
I am looking to retrieve only the ID "hai" using a regular expression in JavaScript. The expected output should be,
var id = regularexpression(data);
The variable id should now contain "hai". Can anyone assist me in writing a regular expression for this in JavaScript?
using a regular expression pattern /(id="(.*?)(\"))/g
Check out the demonstration here
var content='<div id="hai" class="hello">this is div</div>';
console.log(/(id="(.*?)(\"))/g.exec(content)[2])Alternatively
var content='<div id="hai" >this is div</div>';
document.body.innerHTML +=content;
var identifier=document.getElementsByTagName('div')[0].id;
console.log(identifier)To achieve the desired outcome, you can utilize the regex pattern id=\"(.*?)\".
var content='<div id="hello">this is a test</div>';
