Uncaught TypeError: Cannot read property 'push' of undefined

Question

Hello Everyone I have used jquery to generate a textbox.It is generated dynamically through jquery.Now the problem is i want to fetch the textbox value in ajax function and then

Answer 1

This is because you are not setting a value to the variable dynamic_text:

 var dynamic_text;

As such it's value will be undefined. And clearly undefined doesn't have a .push() method; that's what the error is saying:

Cannot read property 'push' of undefined

You will want to define your variable as an array:

var dynamic_text = [];
