ui.datepicker的回显问题

应用场景:

  页面上有一些现有的输入框,需要调用日期插件,同时还要clone一份,动态添加到页面中,动态生成的输入框在调用datepicker的时候,click事件有效,但是选择的时间无法回显到对应的输入框中。

问题分析:

  ui.datepicker.js  添加断点,发现datepicker.js 对 input 控件会自动生成一个id

/* Attach the date picker to a <a href="http://lib.csdn.net/base/jquery" class='replace_word' title="jQuery知识库" target='_blank' style='color:#df3434; font-weight:bold;'>jQuery</a> selection.
       @param  target    element - the target input field or division or span
       @param  settings  object - the new settings to use for this date picker instance (anonymous) */
    _attachDatepicker: function(target, settings) {
        // check for settings on the control itself - in namespace 'date:'
        var inlineSettings = null;
        for (var attrName in this._defaults) {
            var attrValue = target.getAttribute('date:' + attrName);
            if (attrValue) {
                inlineSettings = inlineSettings || {};
                try {
                    inlineSettings[attrName] = eval(attrValue);
                } catch (err) {
                    inlineSettings[attrName] = attrValue;
                }
            }
        }
        var nodeName = target.nodeName.toLowerCase();
        var inline = (nodeName == 'div' || nodeName == 'span');
        if (!target.id)
            target.id = 'dp' + (++this.uuid);

同时,在将 datepicker 附加到 input 控件的时候,如果发现input 控件有this.markerClassName 样式 ( markerClassName: 'hasDatepicker', 109行),则跳出function,不再进行附加。

/* Attach the date picker to an input field. */
    _connectDatepicker: function(target, inst) {
        var input = $(target);
        inst.trigger = $([]);
        if (input.hasClass(this.markerClassName))
            return;


....
}

解决:

首先,将input 控件的id 自增1;然后,去掉 input 控件的'hasDatepicker' 样式:

$("input.clonedp").attr("id", ++$.datepicker.uuid).removeClass("hasDatepicker").datepicker({
        showOn : "both"
        //,appendText : "(yyyy-mm-dd)"
        ,clearText : "Erase"
        ,mandatory : true
        //,closeText : "X"
        ,closeAtTop : false
        ,prevText : "Earlier"
        ,nextText : "Later"
        ,currentStatus: '<a href="http://lib.csdn.net/base/go" class='replace_word' title="Go知识库" target='_blank' style='color:#df3434; font-weight:bold;'>Go</a> to this month'
        //,monthNames:['一月','二月','三月','四月','五月','六月'
        //        ,'七月','八月','九月','十月','十一月','十二月']
        ,monthNames:['1','2','3','4','5','6','7','8','9','10','11','12']
        ,yearRange : "2008:2010"
        ,dateFormat: 'yy-mm-dd'
    });
