Call the onClick function and pass it the value from the element's data- * attribute

I have links like this:

<li><a href="#" data-value="Codes">Get codes</a></li>
<li><a href="#" data-value="Product">Get products</a></li>

How can I do this so that when the link is clicked, then a function is called passing the value contained in the data value?

function refreshGrid(value) { }

Try the following:



$('li > a[href="#"][data-value]').click(function (e) { // On click of all anchors with a data-value attribute and a href of # that are immediate children of li elements (nb this selector can be modifed to suit your needs)
  e.preventDefault(); // prevent the default (navigate to href)
  refreshGrid($(this).data('value')); // call your refreshGrid function with the value contained in the 'data-value' attribute
});

var linkValue = $("li a").attr("data-value");

Edit: better example



$("li a").click(function () {
    var myDataValue = $(this).attr("data-value");
    refreshGrid(myDataValue);
});
