Fill in a form with jQuery

Question

I am trying to use jQuery to fill in a form with some default values.

The form is contained in a div which has an id. In fact every element has an id, I did so just t

Answer 1

To set the value of an input field its

$("#coordX_0").val(123)

Answer 2

Use val method to set the text of any input field.

$("#coordX_0").val(123);

Answer 3

Try this instead, using the val method:

$("#coordX_0").val('some string or number');

Answer 4

All the answers are the exact same so I thought I'd post something different:

var inputs_to_values = {
    'coordX_0' : 'some value',
    'coordY_0' : 'some other value',
    'edit_0'   : 'N',
    'remove_0' : '_',
    'add_0'    : '-',
    'go_0'     : 'stop?'
};
$('#form_coord_0').find('input').val(function (index, value) {
    return inputs_to_values[this.id];
});

You can pass .val() a function, whatever is returned from the function for each element will be the new value:

A function returning the value to set.

this is the current element.

Receives the index position of the element in the set and the old value as arguments.

The above code expects that each input will have a property in the inputs_to_values object so you can convert the ID of the input to the new value for that input.
