Question

Javascript to build a string that includes a date field

Hello,

I'm trying to use a Single Line and a Date field to build a string to store in a hidden field, but I can't get the value from the date field and have tried a number of things.

These are the fields:

And this is my javascript so far. I won't have any problem creating the string once I can get both values.

Does anyone have any ideas? Thanks for looking!

Hi Sarah Webb,

I don't see any error in your code.

Anyway I tried in my own computer and get the result.

This is my code :

$(document).ready(function ()
{
  	$('#q1 input').change(function()
    	{
        	myfunction();            
        });
  
  	$('#q2 input').change(function()
    	{
        	myfunction();            
        });
});

function myfunction(){
  		var string1 = $('#q1 input').val();
 		var date = $('#q2 input').val();
  		var myreturn = string1+" "+date;
        alert(myreturn); 
}

In my mind, you don't have any return because your field date is empty.

And remember, your function start when you change (means focus off) your field.

Hey Sarah,

There is an error in your code. In jQuery, $() is a method that expects a string as a parameter, and returns a list of elements. Instead of a string, you are passing a function definition, which is invalid, and explains why your event listeners do not fire.

Instead of this:

    $(function() {
        $('.Prebale input').change(function() {
            BuildPrevBalStr();
        })
    })

Try this:

    $('.Prebale input').change(function() {
        BuildPrevBalStr();
    })

Which you could shorten down to:

    $('.Prebale input').change(BuildPrevBalStr)
