嘿所有我需要以下html代码才能获得“提供最佳微笑”的价值，这似乎是 6 prev（）和 2 Next （）

我当时的位置是输入标记的达到并保持质量值。

目前我尝试了以下内容：

<div id="eea305a4-32b2-434d-8623-4dc3e2fcf119F_SelectMany" class="lfFormField

var testing 是我试图从中获取该值但却出现“未定义”所以我猜我没有停在正确的位置？

任何帮助都会很棒！

Answer 1

您可以尝试遍历父容器，然后通过它的类对该元素进行查找。

例如：

通过id遍历父级：

$(this).closest('#eea305a4-32b2-434d-8623-4dc3e2fcf119F_SelectMany').find('.form-field-title-sign-css');

按类遍历父级：

$(this).closest('.lfFormField').find('.form-field-title-sign-css');

或通过HTML元素遍历父级：

$(this).closest('fieldset').find('.form-field-title-sign-css');

要获得该值，在这种情况下，您可能希望.text()而不是.html()。当然，除非你真的想要所有的HTML。

最后，如果此ID F_SelectMany-required不是随机的。你可以这样做。这应该有助于它更具体一点。

$(this).closest('.lfFormField').find('#F_SelectMany-required').children('.form-field-title-sign-css');

Answer 2

检查此代码

$(function(){
    var $lbl=$("label[dojoattachpoint='titleNode']");    //Your position
    $lbl.click(function(){
        if (!$("#" + $(this).attr("for")).is(":checked")) {
            var $fieldset=$(this).closest("fieldset");
            alert($("legend",$fieldset).find("span").text());    
        }
    })    
})

Answer 3

Jquery的prev（）为您提供之前的兄弟。在您发布的文档的DOM中，值中的“达到并保持质量”的输入没有任何兄弟姐妹。它是围绕它的跨度的唯一孩子，所以无论你使用prev（）和next（）的组合，你都将得到未定义。你的意思是使用parent（）而不是prev（）吗？但更好的是给那个跨度一个id 带来最好的笑容并使用$（“＃SmileSpanId”）

来实现它

使用jQuery prev（）和next（）查找正确的SPAN标记
