标签: javascript jquery html css

我正在创建一个网站,我想在点击某些部分时更改页面内容。我有CSS,HTML,JS是单独的文件。我是个菜鸟。使用jquery当我给标签(" *")选择所有元素时,我会收到警报,但对于我的生活,我无法选择特定的div。所有div都是唯一的但我真的不知道为什么查询不能选择特定的div。



 $('*').click(function()
    {     alert("The paragraph was clicked.");
     });




---->工作

但这不是



    $('#topbar').click(function(){ 
        alert("The paragraph was clicked.");
     }); 




这是整个代码:



<!doctype html>
<html>
<head>
 <title>dear C</title>
 <meta charset="utf-8" />
 <meta http-equiv="Content-type" content="text/html; charset=utf-8" />
 <meta name="viewport" content="width=device-width, initial-scale=1" />

另请注意,我有CSS html和JS都在单独的文件中。在JS文件中我放了jquery。

确保您没有多个具有相同ID的div(在这种情况下为#topbar),并且您在加载文档后添加了侦听器。

$(document).ready(function(){
    $('#topbar').click(function(){
        alert("The paragraph was clicked.");
    });
});

显示所有HTML代码

  1. 标识符id =“topbar”存在吗?
  2. id =“topbar”在HTML中是唯一的吗?
  3. 您在加载HTML后声明了脚本吗?
  4. <div id="topbar">Go</div>
    <div id="topbar2">Go2</div>
    
    <script type="text/javascript">
    $('#topbar').click(function(){ 
        alert("The paragraph was clicked.");
    });
    </script>
    
    <!-- works -->
