javascript – jQuery .hide()在某些浏览器中不起作用

我们使用jQuery .hide()来隐藏选择输入中的选项 – 一个月内不到31天.它适用于Google Chrome和FireFox,但在Internet Explorer,Opera和Safari中无效.以下是我们使用的 JavaScript 代码：

$(function() {
    // Show and hide days according to the selected year and month.
    function show_and_hide_days(fp_form) {
        var select_year= $(fp_form).find("select.value_year");
        var select_month= $(fp_form).find("select.value_month");
        var select_day= $(fp_form).find("select.value_day");
        var selected_year= parseInt($(select_year).val());
        var selected_month= parseInt($(select_month).val());
        var selected_day= parseInt($(select_day).val());
        var days_in_month= new Date(selected_year,selected_month,0).getDate();
        if ((days_in_month >= 28))
        {
            // If selected day is bigger than the number of days in the selected month,reduce it to the maximal day in this month.
            if (selected_day > days_in_month)
            {
                $(select_day).val(days_in_month);
            }
            // Show all the days in this month and hide days which are not in this month.
            $(select_day).find("option").each(function() {
                var day= parseInt($(this).val());
                if (day <= days_in_month)
                {
                    $(this).show();
                }
                else
                {
                    $(this).hide();
                }
            });
        }
    }
 
    // Show and hide all days in this page.
    function show_and_hide_all_days() {
        $("select.value_day").each(function() {
            var form= $(this).closest("form");
            // Show and hide days according to the selected year and month.
            show_and_hide_days(form);
        });
    }
 
    // Show and hide all days in this page.
    show_and_hide_all_days();
 
    $("select.value_year,select.value_month").live("change",function() {
        var form= $(this).closest("form");
        // Show and hide days according to the selected year and month.
        show_and_hide_days(form);
        return false;
    });
});

这是HTML代码：

<select class="value_year">
    <option value="2000">2000</option>
    <option value="2001">2001</option>
    <option value="2002">2002</option>
    <option value="2003">2003</option>
    <option value="2004">2004</option>
    <option value="2005">2005</option>
    <option value="2006">2006</option>
    <option value="2007">2007</option>
    <option value="2008">2008</option>
    <option value="2009">2009</option>
    <option value="2010">2010</option>
    <option value="2011">2011</option>
    <option value="2012" selected="selected">2012</option>
    <option value="2013">2013</option>
</select>
/
<select class="value_month">
    <option value="1">01</option>
    <option value="2">02</option>
    <option value="3">03</option>
    <option value="4">04</option>
    <option value="5">05</option>
    <option value="6">06</option>
    <option value="7">07</option>
    <option value="8">08</option>
    <option value="9">09</option>
    <option value="10">10</option>
    <option value="11">11</option>
    <option value="12" selected="selected">12</option>
</select>
/
<select class="value_day">
    <option value="1">01</option>
    <option value="2">02</option>
    <option value="3">03</option>
    <option value="4">04</option>
    <option value="5">05</option>
    <option value="6">06</option>
    <option value="7">07</option>
    <option value="8">08</option>
    <option value="9">09</option>
    <option value="10">10</option>
    <option value="11">11</option>
    <option value="12">12</option>
    <option value="13">13</option>
    <option value="14">14</option>
    <option value="15">15</option>
    <option value="16">16</option>
    <option value="17">17</option>
    <option value="18" selected="selected">18</option>
    <option value="19">19</option>
    <option value="20">20</option>
    <option value="21">21</option>
    <option value="22">22</option>
    <option value="23">23</option>
    <option value="24">24</option>
    <option value="25">25</option>
    <option value="26">26</option>
    <option value="27">27</option>
    <option value="28">28</option>
    <option value="29">29</option>
    <option value="30">30</option>
    <option value="31">31</option>
</select>

我们正在使用jQuery v1.8.3(我升级到这个版本来测试它是否修复了问题,但是没有).

谢谢,

解决方法

这是一个浏览器问题,您无法在某些浏览器中隐藏选项,因为$(‘.selector’).hide();类似于$(‘.selector’).css(‘display’,’none’);一些浏览器无法隐藏它

你需要使用$(‘.selector’).remove();和$(‘.selector’).append();

更改代码

if ((days_in_month >= 28))
        {
            // If selected day is bigger than the number of days in the selected month,reduce it to the maximal day in this month.
            if (selected_day > days_in_month)
            {
                $(select_day).val(days_in_month);
            }
            // Show all the days in this month and hide days which are not in this month.
            $(select_day).find("option").each(function() {
                var day= parseInt($(this).val());
                if (day <= days_in_month)
                {
                    $(this).show();
                }
                else
                {
                    $(this).hide();
                }
            });
        }

至

// Remove days 29 - 31
$(select_day).find("option[value='29'],option[value='30'],option[value='31']").remove();
var daysOptions = "";
 
if (days_in_month >= 29) {
    daysOptions += '<option value="29">29</option>';
}
if (days_in_month >= 30) {
    daysOptions += '<option value="30">30</option>';
}
if (days_in_month == 31) {
    daysOptions += '<option value="31">31</option>';
}
 
$(select_day).append(daysOptions);
