Say I have an object with states as properties and an html input text field.
<input id="input" type="text">
var foo = {
"Wisconsin" : "Madison",
"Illinois" : "Springfield"
}
How can I add properties to foo using the input text field ? I tried this :
foo[input.value] = input.value;
but of course it didn't work...
Thanks for your help
foo.newValue = input.value
You are dealing with an object not an array.
So this will result in
{ "Wisconsin" : "Madison", "Illinois" : "Springfield", "newValue" : VALUE-OF-INPUT-FIELD
}
To use normal javascript functions you can use:
foo.input = document.getElementById('input').value;
Or you can use jQuery:
foo.input = $('#input').val();

jQuery .val(): http://api.jquery.com/val/
