Question

I am a new jquery/js user trying to pass an argument from a selector to a function. Here is some of the code:

// function to select data
var data = [
    {val: 10, year: 1990}, {val: 20, year: 1991}
]
var year_data = []
function select_year_data(y) {
    year_data = data.filter(function(d) {return d.year==y})
}

// Selector

<select name="Year" id = "year_menu" style="width: 230px; position: absolute; left: 400px; top: 50px">
<option value=1990>1990</option>
<option value=1991>1991</option>
</select>

What I would like to do is something like this:

<onchange>select_year_data($('#year_menu.val()')

But I know that isn’t quite right.

Answer 1

Jquery change method can be used here Change()

$(function()
{
  $('#year_menu').change(function(){
      select_year_data($(this).val())
  });
});
