Question

我的页面中有以下JQuery。页面加载正常，代码最初工作。如果我编辑textarea字段，再次单击该字段不起作用。有没有办法在编辑textarea之后绑定JQuery功能？

$(document).ready(function() {
$("#prop_notes").dblclick(function() {
    var timestamp = '2013-04-01 20:40:00';
    var userid = '1';
    var username = 'Jim Williams';
    if ($('#prop_notes').val() == '') {
        $("#prop_notes").text("Timestamp: " + timestamp + "\nUser ID: " + userid + "\nUser: " + username);
    }
    else {
        $("#prop_notes").text($("#prop_notes").text() + "\n\n- - - - - - - - - - - - - - - - - - - -\n\nTimestamp: " + timestamp + "\nUser ID: " + userid + "\nUser: " + username);
    }
});

}）;

尝试使用.val（）代替.text（）http://jsfiddle.net/sXkPE/3/

$(document).ready(function () {
    $("#prop_notes").on('dblclick', function () {
        var timestamp = '<?php echo $timestamp; ?>';
        var userid = '<?php echo $user_id; ?>';
        var username = '<?php echo $user_full_name; ?>';
        if ($('#prop_notes').val() == '') {
            $("#prop_notes").val("Timestamp: " + timestamp + "\nUser ID: " + userid + "\nUser: " + username);
        } else {
            $("#prop_notes").val($("#prop_notes").val() + "\n\n- - - - - - - - - - - - - - - - - - - -\n\nTimestamp: " + timestamp + "\nUser ID: " + userid + "\nUser: " + username);
        }
    });
});

删除Textarea后，JQuery停止工作
