在div内获取div

Question

I'm trying to get a div tag inside of another div tag from a javascript, I'm loading content from another page into a div tag so I need to get the div tag to load the page into and also get the div tag to trigger the script when a user clicks on a menu image. 我正在尝试从JavaScript的另一个div标签中获取一个div标签，我正在将另一个页面的内容加载到div标签中，因此我需要获取div标签才能将该页面加载到其中，还需要将div标签添加到当用户单击菜单图像时触发脚本。

Javascript Code JavaScript代码

$('#menu-body a').click(function() {
    var page = $(this).attr('href');
    $('#body-wrap').load('content/' + page + '.php');
    return false;
});

HTML Code HTML代码

<head>

Answer 1

body-wrap is a class in your html. body-wrap是您的html中的类。 meanwhile you state body-wrap as an id in your javascript code. 同时，您在JavaScript代码中将body-wrap声明为ID。 change $("#body-wrap") to $(".body-wrap") , or <div class="body-wrap"></div> to <div id="body-wrap"></div> 将$("#body-wrap")更改$(".body-wrap") ，或将<div class="body-wrap"></div>更改为<div id="body-wrap"></div>

also instead of $("#menu-body a") you must use $(".menu-box a") There is no div with id of menu-body in your html. 也必须使用$(".menu-box a")而不是$("#menu-body a")来代替html中没有带有menu-body id的div。

Answer 2

change your code to below one. 将您的代码更改为以下代码。

#body-wrap represent id body-wrap of div ＃body-wrap代表div的id主体包装

<div id="body-wrap">

.body-wrap represent class body-wrap of div .body-wrap表示div的类body-wrap

 <div class="body-wrap">

  $('.body-wrap').load('content/' + page + '.php');

Answer 3

At first, try to get an idea on class and id selectors in CSS. 首先，尝试了解CSS中的class和id选择器。

An id is selected in CSS using # and a class using . 在CSS中使用#选择ID，并使用在类中选择ID . infront. 在前。

Check this CSS CLASS & ID 检查此CSS CLASS＆ID

Here in your HTML , 在您的HTML中 ，

body-wrap is a class, So you have to select it by using .body-wrap . body-wrap是一类，因此您必须使用.body-wrap进行选择。
There is no elements with id menu-body in your HTML. HTML中没有ID为menu-body元素。 So #menu-body used in your jQuery is an invalid selector. 因此，在jQuery中使用的#menu-body是无效的选择器。 You may use $(".menu-box a") to select anchor tags inside .menu-box 您可以使用$(".menu-box a")在.menu-box选择定位标记
