javascript - 从模态中获取输入值

Question

我对 modal 和 JQuery 都很陌生，并且在获取两个输入值时遇到了困难。

View 中的模态

<div class="col-lg-offset-10 col-lg-2">
        <!-- Modal Button-->
        <span class="item-create-button">
            <button class="btn btn-success btn-block" data-toggle="modal" data-target="#createActor">
                <span style="font-size:larger"><span style="margin-right: 5px" class="glyphicon glyphicon-plus"></span>Add New Actor</span>
            </button>
        </span>

        <!-- Modal -->
        <div class="modal fade" id="createActor" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
            <div class="modal-dialog">
                <div class="modal-content">
                    <div class="modal-header">
                        <button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times;</button>
                        <h4 class="modal-title" id="myModalLabel">Create</h4>
                    </div>
                    <div class="modal-body">

                        <table class="table" id="createTable">
                            <tr>
                                <th class="col-lg-4">
                                    <h5 style="font-size:x-large"><span style="font-weight:bolder">Name</span></h5>
                                </th>
                                <th class="col-lg-7 col-lg-offset-1">
                                    <input type="text" name="createName" style="text-align: center; height: 35px; font-size: 20px; width: 100%" placeholder="Name" />
                                </th>
                            </tr>
                            <tr>
                                <th class="col-lg-4">
                                    <h5 style="font-size:x-large"><span style="font-weight:bolder">Birthday</span></h5>
                                </th>
                                <th class="col-lg-7 col-lg-offset-1">
                                    <input type="text" name="createBirthday" style="text-align:center; height:35px; font-size:20px; width:100%" placeholder="Birth (mm/dd/yyyy)" />
                                </th>
                            </tr>
                        </table>

                    </div>
                    <div class="modal-footer">
                        <button type="button" onclick="createFunction(this)" class="btn btn-success">Create</button>
                        <button type="button" class="btn btn-default" data-dismiss="modal">Cancel</button>
                    </div>
                </div>
            </div>
        </div>
    </div>

JQuery“尝试”

function createFunction(element) {
    var name = $(element).prev("div").closest("table").find("#createName").attr('value');
    var name1 = $(element).prev("div").closest("table").find("#createName").val();
    var birth = $(element).prev("table").next("input.col-lg-7").find(":input:first").val();
    var check = $(element).closest("table").attr("class");
    alert(name, name1, birth, check);
}

我尝试寻找更多有用的示例，但我只是迷失了 JQuery 的所有搜索功能(前、下、最近、查找等...)的工作方式

如果有人可以帮助我解决这个问题，并可能向我指出有助于阐明所有这些搜索功能的好文章，我将永远感激不已! :)

您可以使用parent()和sibling()关系来获取模型主体，然后像标准的嘶嘶声选择

//.parent() is modal-footer
//.parent().prev() is modal-body
//.parent().prev().find("#createName") is the input element
var name = $(element).parent().prev().find("#createName");

我相信您能够从这里找到其他人。
