创建一个动态领域并获得价值

Question

i posted another question about this, but i think this one will be more concise.

i've dynamically created a text field with javascript. i've checked to see that it's in the DOM by getting its value, but when trying to access it from another function i get a value of null for the input object. is it actually possible to get the current value from a dynamically created text field?

inside one function:

comment_field = 'comment-HE382U3-2';
document.getElementById(comment_field).value = 'Write a comment...';

inside the other:

comment_field = 'comment-HE382U3-2';
if (document.getElementById(comment_field).value == 'Write a comment...')
    { document.getElementById(comment_field).value = '';}

is not happening because there is no [HTMLInputObject] found in the DOM. Please help. Thanks!

Answer 1

is it actually possible to get the current value from a dynamically created text field?

Yes. It is just like any other element. If it is in the DOM, it is accessed the same way.

Verify the value of the comment_field variable. You're making reference to different functions, so perhaps that variable is out of scope.
