Question

我对此代码存在一些问题：

    <script type="text/javascript" language="javascript">
        $(document).ready(function(){
            $( "#continue" ).click(function() {
            var c = $('[name="recaptcha_challenge_field"]').attr('name');
            var r = $('[name="recaptcha_response_field"]').attr('name');
            alert( "c=" + c );
            alert( "r=" + r );
            });
        });
    </script>

单击标识为continue的按钮时，警报框不会显示。我的代码有问题吗？

Answer 1

您没有用于文档就绪的结束函数包装器。所以它应该是：

<script type="text/javascript" language="javascript">
$(document).ready(function(){
    $( "#continue" ).click(function() {
        var c = $('[name="recaptcha_challenge_field"]').attr('name');
        var r = $('[name="recaptcha_response_field"]').attr('name');
        alert( "c=" + c );
        alert( "r=" + r );
    });
});

你错过了一个clossing })：

$(document).ready(function(){
    $( "#continue" ).click(function() {
        var c = $('[name="recaptcha_challenge_field"]').attr('name');
        var r = $('[name="recaptcha_response_field"]').attr('name');
        alert( "c=" + c );
        alert( "r=" + r );
    });
}); // <<<<<==== THIS IS MISSING

jQuery click（）事件没有触发
