Why value is coming same on click?

问题

我有两个Table TR,其中定义了带有fa-chevron-down Font Awesome图标的控件类型。

我想要:
当我点击fa-chevron-down Font Awesome图标时,打开一个控件类型,现在有两种类型(输入控件电子邮件控件),但它可能有多个。

当我点击控件类型时,它会更改Table TR中给定的主要值。

第一次点击fa-chevron-down Font Awesome图标时它可以正常工作,但是当我点击第二次fa-chevron-down时,两个Table TR的值都会更改,我为什么无法理解。

我的代码:

<!-- 开始代码段 -->
<!-- JavaScript代码 -->
$('body').on('click', '.select-response-type-btn', function (e) {
    var thisClick = $(this);
    $('.select-response-type-box').show();
    $('.response-menu-item').click(function () {
        var thisMunuItemHtml = $(this).html();
        $('.select-response-type-box').hide();
        $(thisClick).prev('.response-menu-item').html(thisMunuItemHtml);
    });
});

<!-- CSS代码 -->
.d-custom-none { display: none; }
.select-response-type-box { border: 1px solid #ccc; padding: 10px; }

将代码段添加到你的项目中,它应该能够正常工作。

英文:

I have two Table TR there is define control types with fa-chevron-down font awesome icon.

I want:
When i click on fa-chevron-down font awesome icon then open a control types now its two types (input control and email control) but it may be multiple.

When i click on control types then it is change the main value which are given in Table TR.

It is working fine for first fa-chevron-down font awesome icon click when i click on second fa-chevron-down then both Table TR value changed, why i'm not able to understand.

得分: 1

  1. 为什么要使用 HTML 表格?在 div 和 tr 之间获取 index 很困难。

  2. 最重要的是 jQuery 选择器 .select-response-type-btn 返回错误的位置。你必须打印点击的索引,像这样:clickIndex = $(this).parent().parent().parent().index(); 如果 clickIndex 返回正确的索引,那么你的示例将正常工作。

英文:

I spent a lot of time made an working example.
jsfiddle

var clickIndex = 0;
$(&#39;body&#39;).on(&#39;click&#39;, &#39;.select-response-type-btn&#39;, function () {
clickIndex = $(this).parent().parent().parent().index();
console.log(clickIndex);
var thisClick = $(this);
$(&#39;.select-response-type-box&#39;).show();
$(&#39;.response-menu-item&#39;).click(function () {
var thisMunuItemHtml = $(this).html();
$(&#39;.select-response-type-box&#39;).hide();
$(&#39;.type-selector&#39;).find(&#39;.response-menu-item&#39;).eq(clickIndex).html(thisMunuItemHtml);
//$(thisClick).prev(&#39;.response-menu-item&#39;).html(thisMunuItemHtml);
});
});
  1. Why you use HTML Table ?? It's hard to get index between div and tr.

  2. The most important is jquery selector .select-response-type-btn return wrong position. you must print click index like clickIndex = $(this).parent().parent().parent().index(); if clickIndex return correct index then your example will working.
