[英]How can i remove different items on same page
我如何在不重新加载页面的情况下删除同一页面上的不同项目,就像我想删除一些项目并留下 rest
<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
<script>
$(document).ready(function(){
$("button").click(function(){
$("p").remove();
});
});
</script>
</head>
<body>
<div>
<p>remove this paragraph</p><button>close</button>
<p>leave this paragraph</p><button>close</button>
<p>remove this paragraph</p><button>close</button>
<p>leave this paragraph</p><button>close</button>
</div>
</body>
</html>
这里有一种方法可以删除按钮和按钮的上一段:
$(document).ready(function(){
$('button').click(function(){
$( this ).prev('p').remove();
$( this ).remove();
});
});
好吧,您需要更改 html 以定位要为其添加自定义class
的项目,例如:
<p>remove this paragraph</p><button>close</button>
<p>leave this paragraph</p><button>close</button>
<p class="item-to-remove">remove this paragraph</p><button>close</button>
<p>leave this paragraph</p><button>close</button>
因此您还需要更改 javascript 中的 CSS 选择器:
$(document).ready(function(){
$("button").click(function(){
$(".item-to-remove").remove();
});
});
