我有一个显示表单的 JQuery UI 对话框弹出窗口。通过单击添加更多按钮，我可以将新表单添加到 JQuery UI 对话框中。

单击添加新按钮时，如何使 JQuery UI 对话框自动滚动并向用户显示新的空白表单。

添加了分区

<div>
    <form id="1">
        <label class="dbright">DashBoard ID:</label><span class="dbleft"><select id="dashboard_id" class="dbSettingDD"><option>-------Select-------</option><option id="#dashboard">Inventory</option><option id="#dashboard2">Quality</option><option id="#dashboard3">Complaints</option></select><br></span>

        <label class="dbright">Filtering parameter:</label><span class="dbleft"><select id="filter_by"><option>-------Select-------</option></select><br></span>

        <label class="dbright">Y-Axis:</label><span class="dbleft"><select id="yAxis"><option>-------Select-------</option></select><br></span>

        <label class="dbright">Chart Tiltle:</label><span class="dbleft"><input type="text" id="title"><br></span>

        <label class="dbright">Chart Type:</label><span class="dbleft"><input type="text" id="chart_type"><br></span>

        <label class="dbright">Main Chart:</label><span class="dbleft"><input type="radio" name="mainchart" value="yes">Yes <input type="radio" name="mainchart" value="No">No<br></span>

    </form>
</div>

对话

$("#dbSetting_div").dialog({
    height: 315,
    width: 500,
    autoOpen: false,
    modal: true,
    draggable: false,
    buttons: {
        "Save": function () {},
        "Add More": function () {
            l_i++;
            formHtml = "<div>";
            formHtml += "<form id='" + l_i + "'>";
            formHtml += "<label class = 'dbright'>DashBoard ID: </label><span class = 'dbleft'><select id='dashboard_id' class='dbSettingDD'><option>-------Select-------</option>" + dropDownDashboardName + "</select></br></span>";
            formHtml += "<label class = 'dbright'>Filtering parameter: </label><span class = 'dbleft'><select id='filter_by'><option>-------Select-------</option></select></br></span>";
            formHtml += "<label class = 'dbright'>Y-Axis: </label><span class = 'dbleft'><select id='yAxis'><option>-------Select-------</option></select></br></span>";
            formHtml += "<label class = 'dbright'>Chart Tiltle: </label><span class = 'dbleft'><input type='text' id='title'/></br></span>";
            formHtml += "<label class = 'dbright'>Chart Type: </label><span class = 'dbleft'><input type='text' id='chart_type'/></br></span>";
            formHtml += "<label class = 'dbright'>Main Chart: </label><span class = 'dbleft'><input type='radio' name='mainchart' value='yes'/>Yes <input type='radio' name='mainchart' value='No'/>No</br></span>";
            formHtml += "</form>";
            formHtml += "</div>";
            $("#dbSetting_div").append("<p>" + formHtml + "</p>");
            console.log(scroll);
        }
    }
}).css("font-size", "12px");

这就是我的做法，尤其是添加表单的新 HTML。

首先，我会将 HTML 添加到页面，并显示none和某种templateID，如下所示：

<div id="formTemplate" style="display: none;">
    <form id="1">
        <label class="dbright">DashBoard ID:</label><span class="dbleft"><select id="dashboard_id" class="dbSettingDD"><option>-------Select-------</option><option id="#dashboard">Inventory</option><option id="#dashboard2">Quality</option><option id="#dashboard3">Complaints</option></select><br></span>
        <label class="dbright">Filtering parameter:</label><span class="dbleft"><select id="filter_by"><option>-------Select-------</option></select><br></span>
        <label class="dbright">Y-Axis:</label><span class="dbleft"><select id="yAxis"><option>-------Select-------</option></select><br></span>
        <label class="dbright">Chart Tiltle:</label><span class="dbleft"><input type="text" id="title"><br></span>
        <label class="dbright">Chart Type:</label><span class="dbleft"><input type="text" id="chart_type"><br></span>
        <label class="dbright">Main Chart:</label><span class="dbleft"><input type="radio" name="mainchart" value="yes">Yes <input type="radio" name="mainchart" value="No">No<br></span>
    </form>
</div>

然后，我可以使用它add method来快速克隆我需要的材料，删除显示无，然后粘贴新表格！像这样：

$("#dbSetting_div").css("font-size", "12px").dialog({
    height: 315,
    width: 500,
    autoOpen: false,
    modal: true,
    draggable: false,
    buttons: {
        "Save": function () { /*    do work */ },
        "Add More": function () {
            $("#dbSetting_div").append($('<p />').append($('#formTemplate').clone().show()))
                .animate({ scrollTop: $('#dbSetting_div')[0].scrollHeight}, 500);
        }
    }
});

在其中，每当添加新表单时，我.animate都会将对话框滚动到底部。您也可以直接更改并跳过动画，例如：$("#dbSetting_div").scrollTop($('#dbSetting_div')[0].scrollHeight);

无论如何，这应该可以帮助您入门。如果您需要更多帮助，请告诉我。现在，查看
