如何设置通过jQueryUI datepicker小部件获取值的动态添加的input字段的宽度?

我有2个输入,“日历输入”是我们选择日期的地方,它将通过altField方法(datepicker的核心方法)自动添加到我们的附加输入中。那么我可以动态调整input使其更小\更大吗?

Additional input: <input type="text" id="alternate" value="December,19 2015"><br>
Calendar input: <input type="text" id="from">    
$("#from").datepicker({
    defaultDate: "+1w",
    changeMonth: true,
    numberOfMonths: 1,
    altField: "#alternate",
    altFormat: "MM d, yy",
    onClose: function (selectedDate) {
        $("#to").datepicker("option", "minDate", selectedDate);
    }
});

你的意思是这样吗?

    $("#from").datepicker({

    defaultDate: "+1w",
    changeMonth: true,
    numberOfMonths: 1,
    altField: "#alternate",
    altFormat: "MM d, yy",
    onClose: function (selectedDate) {
        $("#to").datepicker("option", "minDate", selectedDate);
        $('input').css('width','auto');
    }
});

由于您只想在日期选择器日期选择上做一些事情,您只需在日期选择器的onCloseonSelect回调中添加您的内容

示例:

    $("#from").datepicker({
        defaultDate: "+1w",
        changeMonth: true,
        numberOfMonths: 1,
        altField: "#alternate",
        altFormat: "MM d, yy",
        onClose: function (selectedDate) {
            // do you stuff over here
            $("#alternate").width(100).removeClass("disabled");

            $("#to").datepicker("option", "minDate", selectedDate);
        }
    });

基本输入自动调整插件(只是扩展 isValidWidthChange one的限制):

Segmentation faults

也可以添加这些行:

(function($){
    $.fn.autoResizeInput= function(o) {

    o = $.extend({
        maxWidth: 1000,
        minWidth: 0,
        comfortZone: 70
    }, o);

    this.filter('input:text').each(function(){

        var minWidth = o.minWidth || $(this).width(),
            val = '',
            input = $(this),
            testSubject = $('<tester/>').css({
                position: 'absolute',
                top: -9999,
                left: -9999,
                width: 'auto',
                fontSize: input.css('fontSize'),
                fontFamily: input.css('fontFamily'),
                fontWeight: input.css('fontWeight'),
                letterSpacing: input.css('letterSpacing'),
                whiteSpace: 'nowrap'
            }),
            check = function() {

                if (val === (val = input.val())) {return;}

                // Enter new content into testSubject
                var escaped = val.replace(/&/g, '&amp;').replace(/\s/g,'&nbsp;').replace(/</g, '&lt;').replace(/>/g, '&gt;');
                testSubject.html(escaped);

                // Calculate new width + whether to change
                var testerWidth = testSubject.width(),
                    newWidth = (testerWidth + o.comfortZone) >= minWidth ? testerWidth + o.comfortZone : minWidth,
                    currentWidth = input.width(),
                    isValidWidthChange = ( (newWidth < currentWidth || newWidth > currentWidth )&& newWidth >= minWidth)
                                         || (newWidth > minWidth && newWidth < o.maxWidth);

                // Animate width
                if (isValidWidthChange) {
                    input.width(newWidth);
                }

            };

        testSubject.insertAfter(input);

        $(this).bind('keyup keydown blur update', check);

    });

    return this;

    };
})(jQuery);
