来自循环内第一个div的弹出内容

Question

弹出窗口在整个循环中显示相同的内容。下面是循环内的代码。

 <div class="title popupReturn"><%= item.name %></div>

    <div id="tableContent" style="display:none">
        <div>
            <div class="panel panel-default">
                <div class="panel-heading"><%= item.name %></div>
                <div class="panel-body form-inline dept1">
                    <a class="btn btn-default" id="001">Item</a>
                </div>
            </div>
        </div>
    </div>
  </div>

这是inpage脚本调用。循环之外

<script>
        $().ready(function(e) {

            var popupEvent = function() {

            }

            $('.popupReturn').hunterPopup({
                width: '320px',
                height: '200px',
                title: "jQuery hunterPopup Demo",
                content: $('#tableContent'),
                event: popupEvent
            });

        });
    </script>

Answer 1

html ID属性在所有当前代码中必须是唯一的。当你在一个循环中创建一个id为这样的id的div时，你将有多个具有相同id的div，然后当你用“content：$（'＃tableContent'）”初始化你的popovers时，你传递了第一个#tableContent对于所有情况。

Answer 2

首先：ID必须是唯一的。第二：我建议你为每个项目添加一个数据属性，如下所示：

<div class="title popupReturn" data-id="tableContent1">Item1</div>

通过这种方式，您的 popupEvent 函数可以获取当前点击的项目，因此它可以动态更改猎人弹出内容，如：

 var popupEvent = function () {
    var id = $('.popupReturn.clicked').data('id');
    this.content.replaceWith($('#' + id).html());
}

$('.popupReturn').on('click', function(e) {
    $('.popupReturn.clicled').removeClass('clicked');
    $(this).addClass('clicked');
}).hunterPopup({
    width: '320px',
    height: '200px',
    title: "jQuery hunterPopup Demo",
    event: popupEvent
})

(function($) {
    $.hunterPopup = function(box, options) {
        var box = $(box);
        var defaults = {
            title: 'jQuery hunterPopup Demo',
            placement: 'left',
            width: '100%',
            height: '100%',
            content: $('<div><h3>jQuery hunterPopup Demo</h3></div>'),
            event: closePopup
        };
        var obj = $.extend(defaults, options);

        var template = $('<div class="Hunter-pop-up" id="Hunter-pop-up"><a class="close"><i class="glyphicon glyphicon-remove"></i></a><div class="arrow"></div><h3 class="title"></h3><div id="Hunter_pop_wrap" class="Hunter-wrap"></div></div>');
        var title = $('.title', template);
        var pop_wrap = $('#Hunter_pop_wrap', template);

        $(document).click(function() {
            template.remove();
        });

        box.click(function(event) {
            event.preventDefault();
            event.stopPropagation();
            $('.Hunter-pop-up').remove();
            var _this = $(this);
            var offset = _this.offset();
            var top = offset.top + _this.outerHeight() + 15;
            if(obj.placement == 'left') {
                template.css({
                    'left': offset.left,
                    'top': top
                });
            } else {
                template.addClass("Hunter-pop-up-right");
                template.css({
                    'left': offset.left - obj.width + _this.width() / 2,
                    'top': top
                });
            }

            buildPopup();
            $('body').append(template);
            $('.Hunter-pop-up').click(function(event) {
                event.stopPropagation();
            });

            //调用弹出层内容注册的事件。
            obj.event();

        });

        function buildPopup() {
            buildPopupContent();
            closePopup();
        };

        function buildPopupContent() {
            title.text(obj.title);

            //构造弹出层的内容
            var _content = obj.content;
            _content.show();
            pop_wrap.children().remove();
            pop_wrap.append(_content);
            pop_wrap.width(obj.width);
            pop_wrap.height(obj.height);
        };

        function closePopup() {
            template.on('click', '.close', function(event) {
                event.preventDefault();
                event.stopPropagation();
                template.remove();
            });
        }
    };

    $.fn.extend({
        hunterPopup: function(options) {
            options = $.extend({}, options);
            this.each(function() {
                new $.hunterPopup(this, options);
            });
            return this;
        }

    });
})(jQuery);
