先上效果：

基于jquery UI 1.11.4修改如下（在源码里面修改）：
/* Hide the date picker from view. * @param input element - the input field attached to the date picker */ _hideDatepicker: function(input) { var showAnim, duration, postProcess, onClose, inst = this._curInst; if (!inst || (input && inst !== $.data(input, "datepicker"))) { return; } /** * 2015.6.11 修改 * author：link * 增加inst.autoClose控制日历面板 */
// -----------------------------------------------------------------------------------------
if (this._datepickerShowing||!inst.autoClose) { showAnim = this._get(inst, "showAnim"); duration = this._get(inst, "duration"); postProcess = function() { $.datepicker._tidyDialog(inst); }; // DEPRECATED: after BC for 1.8.x $.effects[ showAnim ] is not needed if(inst.autoClose===true){ // 这里不隐藏 }else{ if ( $.effects && ( $.effects.effect[ showAnim ] || $.effects[ showAnim ] ) ) { inst.dpDiv.hide(showAnim, $.datepicker._get(inst, "showOptions"), duration, postProcess); } else { inst.dpDiv[(showAnim === "slideDown" ? "slideUp" : (showAnim === "fadeIn" ? "fadeOut" : "hide"))]((showAnim ? duration : null), postProcess); } }
// -----------------------------------------------------------------------------------------
if (!showAnim) { postProcess(); } this._datepickerShowing = false; onClose = this._get(inst, "onClose"); if (onClose) { onClose.apply((inst.input ? inst.input[0] : null), [(inst.input ? inst.input.val() : ""), inst]); } this._lastInput = null; if (this._inDialog) { this._dialogInput.css({ position: "absolute", left: "0", top: "-100px" }); if ($.blockUI) { $.unblockUI(); $("body").append(this.dpDiv); } } this._inDialog = false; } },
1.11.4修改后完整源码
