The id of my textarea is string and of this format




id='fisher[27].man'




I would like to clone the textarea and increment the number and get the id as fisher[28].man and prepend this to the existing textarea.



Is there a way to get this done easily with jquery?



var existingId = $(#at textarea:last).attr('id');

var newCloned = lastTextArea.clone();

var newId = newCloned.attr('id');

//add the index number after spliting

//prepend the new one to 

newCloned.prepend(<tr><td> + newCloned + </td></tr>);


There has to be easier way to clone, get index number, split and prepend.



I'm have also tried to do this with regEx 



var existingIdNumber = parseInt(/fisher[(d+)]/.exec(s)[1], 10);


Can anybody help me with this?

Correct regex would be this



/fisher[d+].man/


Here is a way through through which you would extract the the id.



id = text.replace(/fisher[(d+)].man+/g,$1);

//Now do whatever you want with the id


Similarly, Same replacement technique can be used to get an incremented id as:



existingId = 'fisher[27].man';

newId = existingId .replace(/(d+)+/g, function(match, number) {

       return parseInt(number)+1;

});

console.log(newId);


Demo with both usage
