Merging the Content of 3 Fields Before Form Submission
I have a form with a series of text fields.
3 of them have to be combined into a hidden field before submission.
I have found http://jsfiddle.net/Tyriar/5ERRG/ a few hours ago and I am trying to adapt it to a form.
The <div id="output"></div> would be the hidden input.
And <button id="test">Test</button> would be replaced by the submit button.
In the first place, after editing the code and changing <div id="output"></div> for <input id="output"/> the fourth field does not receive any content from the 3 fields above, so I have no tested it in a form.
Some idea on how to adapt the code to my project?
If such a thing is possible.
In other case, I would appreciate some other way to do it.
Thanks for your help.
You can't set the innerHTML of an input. You have to set the value. See here:
Thanks. I'll try with it.
