Hi I have a div that contains three textboxes , i need a function to be called once the control is out of the div tag, I don't want to use the onclick event because the focus can be moved out of the div by pressing the tab key on the keyboard or some other way. I would also like to know if there is a way to achieve this using any javascript libraries like jquery.

Thank you, this is the sample html code

<html>
<head>
    <title>Div Onblur test</title>

    <script type="text/javascript">
        function Callme() {
            alert("I am Called")
        }
    </script>

</head>
<body>
    <div onblur="javascript:Callme();">
        <input type=text value ="Inside DIV 1" />
        <input type=text value ="Inside DIV 2" />
        <input type=text value ="Inside DIV 3" />
    </div>
     <input type=text value ="Outside DIV" />
</body>
</html>

您需要将 tabindex=0 添加到 div 以使其获得焦点。所以像

<div tabindex="-1" onblur="Callme();">

应该这样做。

您可以将 onblur 事件处理程序绑定到每个输入元素，并检查处理程序中是否有任何一个具有焦点（使用document.activeElement）。

<script type="text/javascript">
    function checkBlur() {
        setTimeout(function () {
            if (document.activeElement != document.getElementById("input1") &&
                document.activeElement != document.getElementById("input2") &&
                document.activeElement != document.getElementById("input3")) {
                alert("I am called");
            }
        }, 10);
    }
</script>
<!-- ... -->
<div>
    <input type="text" id="input1" value="Inside DIV 1" onblur="checkBlur()" />
    <input type="text" id="input2" value="Inside DIV 2" onblur="checkBlur()" />
    <input type="text" id="input3" value="Inside DIV 3" onblur="checkBlur()" />
</div>
<input type="text" value="Outside DIV" />

或者，相反，使用 jQuery 可以简化流程（特别是如果您有很多输入）：

<script type="text/javascript" src="http://code.jquery.com/jquery-latest.js"></script>
<script type="text/javascript">
    $(document).ready(function () {
        $("#theDiv input").bind("blur", function () {
            setTimeout(function () {
                var isOut = true;
                $("#theDiv input").each(function () {
                    if (this == document.activeElement) isOut = false;
                });
                if (isOut) {
                    // YOUR CODE HERE
                    alert("I am called");
                }
            }, 10);
        });
    });
</script>
<!-- ... -->
<div id="theDiv">
    <input type="text" value="Inside DIV 1" />
    <input type="text" value="Inside DIV 2" />
    <input type="text" value="Inside DIV 3" />
</div>
<input type="text" value="Outside DIV" />

编辑：我将事件处理程序包装在 asetTimeout中，以确保其他元素有时间关注。

我在一个类似的场景中使用了以下 jQuery 脚本，其中一个 div 中有 3 个文本框：

<script type="text/javascript">
    $(document).ready(function () {
        $("jQuerySelectorToGetYourDiv").focusout(function (e) {
            if ($(this).find(e.relatedTarget).length == 0) {
                // Focus is now outside of your div. Do something here.
                // e.Target will give you the last element within the
                // div to lose focus if you need it for processing.
            }
        });
    });
</script>

也许“onChange”事件会更好地满足您的需求。我想不出会单击 DIV 而不是输入字段的情况。
