每个数组值的 Jquery 函数答案

【问题标题】：Jquery function for every array value每个数组值的 Jquery 函数
【发布时间】：2019-03-13 21:03:15
【问题描述】：

我有一个一维数组（表示输入容器的类）。有一些输入容器作为数组中包含的数字。

我不想为每个值编写所有函数，所以我使用了带有Jquery.each的数组。

但是这段代码不起作用，我不明白为什么我不知道 Jquery.each 的确切语法。

抱歉英语不好。

谁能帮帮我？

jQuery(document).ready(function($) {
    $('.selezioneprovincia input').bind('change', function() {
        var arr = [".AG",".AL",".AN",".AO",".AR",".AP",".AT",".AV",".BA",".BT",".BL",".BN",".BG",".BI",".BO",".BZ",".BS",".BR",".CA",".CL",".CB",".CI",".CE",".CT",".CZ",".CH",".CO",".CS",".CR",".KR",".CN",".EN",".FM",".FE",".FI",".FG",".FC",".FR",".GE",".GO",".GR",".IM",".IS",".SP",".AQ",".LT",".LE",".LC",".LI",".LO",".LU",".MC",".MN",".MS",".MT",".ME",".MI",".MO",".MB",".NA",".NO",".NU",".OT",".OR",".PD",".PA",".PR",".PV",".PG",".PU",".PE",".PC",".PI",".PT",".PN",".PZ",".PO",".RG",".RA",".RC",".RE",".RI",".RN",".RM",".RO",".SA",".VS",".SS",".SV",".SI",".SR",".SO",".TA",".TE",".TR",".TO",".OG",".TP",".TN",".TV",".TS",".UD",".VA",".VE",".VB",".VC",".VR",".VV",".VI",".VT"];
        jQuery.each( arr, function( i, val ) {
            if( $('.selezioneprovincia' + val + ' input').is(':checked') ){
                $('.selezionepv '+ val).show();  // checked
            } else {
                $('.selezionepv '+ val).hide();  // unchecked
                $('.selezionepv ' + val + ' input').prop("checked", false);
            }
        });
    });
});

【问题讨论】：

HTML 是什么？
你想达到什么目的？
您好，该 html 很长，因为是使用 wordpress 插件创建的。我希望每个输入单选都检查一个类（包含在数组中），如果选中则显示另一个 div 并检查另一个 div 中的其他输入单选，否则不显示并取消选中它。
为了使问题有用和/或可回答，HTML 需要可见，以便人们可以使用minimal reproducible example，否则回答者只会猜测。
有趣的是，foreach 循环实际上并没有错。当我使用记录器在快速示例中执行 foreach 时，它可以正常工作。我预计问题确实出在 HTML 部分......你不能提供输入如何呈现的简短片段吗？

标签： jquery arrays each

【解决方案1】：

.selezioneprovincia 后面少了一个“”，应该是：

jQuery(document).ready(function($) {
$('.selezioneprovincia input').bind('change', function() {
    var arr = .....;
    jQuery.each( arr, function( i, val ) {
        if( $('.selezioneprovincia ' + val + ' input').is(':checked') ){
            ....
    });
});
});

【讨论】：

【解决方案2】：

您可以使用简单的for 循环：

$('.selezioneprovincia input').on('change', function() {
    var arr = [...];
    for (var i in arr) {
        var val = arr[i];
        var elem = $('.selezionepv '+ val);
        if ($(this).is(':checked')) {
           elem.show();
        } else {
           elem.hide().find('input').prop('checked', false);
        }
    }
});

【讨论】：

嗨，谢谢。我试过了，我注意到它显示了所有包含在数组中的类的 div。我希望只为所选课程显示相应的 selezionepv 谢谢

【解决方案3】：

jQuery 选择器中缺少空格：

if( $('.selezioneprovincia ' + val + ' input').is(':checked') )

我将数组从更改处理程序中移开。

完整的js代码：

$(function() {

var arr = [".AG",".AL",".AN",".AO",".AR",".AP",".AT",".AV",".BA",".BT",".BL",".BN",".BG",".BI",".BO",".BZ",".BS",".BR",".CA",".CL",".CB",".CI",".CE",".CT",".CZ",".CH",".CO",".CS",".CR",".KR",".CN",".EN",".FM",".FE",".FI",".FG",".FC",".FR",".GE",".GO",".GR",".IM",".IS",".SP",".AQ",".LT",".LE",".LC",".LI",".LO",".LU",".MC",".MN",".MS",".MT",".ME",".MI",".MO",".MB",".NA",".NO",".NU",".OT",".OR",".PD",".PA",".PR",".PV",".PG",".PU",".PE",".PC",".PI",".PT",".PN",".PZ",".PO",".RG",".RA",".RC",".RE",".RI",".RN",".RM",".RO",".SA",".VS",".SS",".SV",".SI",".SR",".SO",".TA",".TE",".TR",".TO",".OG",".TP",".TN",".TV",".TS",".UD",".VA",".VE",".VB",".VC",".VR",".VV",".VI",".VT"];


$('.selezioneprovincia input').bind('change', function() {        

    $.each( arr, function( i, val ) {
        if( $('.selezioneprovincia ' + val + ' input').is(':checked') ){
            $('.selezionepv '+ val).show();  // checked
        } else {
            $('.selezionepv '+ val).hide();  // unchecked
            $('.selezionepv ' + val + ' input').prop("checked", false);
        }
    });

   });
 });

工作示例。它从显示的所有输入开始。
