javascript - 无法手动打开 Jquery Datepicker

Question

我正在尝试手动打开 jquery datepicker(仅在自定义按钮单击事件上。日期选择器不应在选择文本框时启动)，但它不起作用。

我错过了什么吗？

$(function() {
    $('#InputExpirationDateBtn').on('click', function () {
            $('#InputExpirationDateTxtBox').datepicker("show");
        });
});

          </div>
        </div>
      </div>
    </div>
  </div>
</div>
</div>

<div class="modal-footer">
  <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
  <button type="button" class="btn btn-primary">Save changes</button>
  </div>
    </div><!-- /.modal-content -->
  </div><!-- /.modal-dialog -->
</div><!-- /.modal -->

期望

日期选择器应仅在按钮单击事件上显示，并且所选值应填充在附近的文本框中。

Answer 1

有两件事:

需要设置z-index

#ui-datepicker-div {
    z-index:1151 !important;
}

需要在点击之前定义日期选择器

$("#InputExpirationDateTxtBox").datepicker({
    showOn:'none' //making the datapicker show on nothing
});

这对你有用。 https://jsfiddle.net/z39q8wff/2/

只是想让你知道。还有一个替代方案How can I extend jQueryUI datepicker to accept an additional argument?
