Changing form serialize data

Question

after a JS form serialize i have this:

.....&xx=xxx&otherError=&input=SMS&message=sdfgs&......

How can i change message val before ajax call putting a textarea val?

Thanks in advance,

Answer 1

Using String#replace method update the string.

var str = '.....&xx=xxx&otherError=&input=SMS&message=sdfgs&......';

str = str.replace(/&message=[^&]+/, '&message=newvalue');

console.log(str);

Or update the input field value before serializing.

$('[name="message"]').val('newvalue');
