how to get the element on which taphold is fired(jquery mobile)

问题

Can you please help me to locate on which element "taphold" is fired by using js, jquery or jq mobile. my html structure is like mentioned below

<script>
    $(document).on("pagecreate", function () {      
        $("#myFilesListView").bind('contextmenu', function (event) {
            event.preventDefault();
            event.stopPropagation();
            return false;
        });
    });
    $(document).ready(function () {
        $("#myFilesListView").bind("taphold", function (event) {
            event.preventDefault(false);
            event.stopPropagation();           
            var ID = $(this).child().attr("id");
            alert(ID);
        });
    });
</script>

    <div data-role="page" id="page1">
        <div data-role="header"></div>
        <div data-role="main">
            <ul data-role="listview" id="mylistview">
                <li class="mydata" id="1"> some conetent</li>
                <li class="mydata" id="2"> some conetent</li>
                <li class="mydata" id="3"> some conetent</li>
                <li class="mydata" id="4"> some conetent</li>
                <li class="mydata" id="5"> some conetent</li>
              <!--ids are not in predefined sequences and there may be 100s of list--> 
            </ul>
        </div>
 <div data-role="fotter"></div>
</div>

in my javascript code I am able to prevent the default behavior of taphold, but I am not getting how to get the Id of a particular list as soon as a user tap and hold on that list.

回答1:

You can bind the taphold to the li elements instead of the listview:

$(document).on("pagecreate", "#page1", function () {      
    $("#mylistview").on('contextmenu', function (event) {
        event.preventDefault();
        event.stopPropagation();
        return false;
    });

    $("#mylistview li").on("taphold", function (event) {
        var ID = $(this).prop("id");
        alert(ID);
    });
});
