这段代码存在多个空缺,我将逐一解释:
```
$('#messageContent').on('click',function(){ //绑定事件
//切换效果
$('.message').eq(3).hide('blind',500); //第3个元素隐藏,动画为盲目效果,动画时间为500毫秒
setTimeout(function(){
//输入框高度变高动画
$('textarea').animate({ //选择所有的textarea元素,并进行动画
height:'200px' //动画属性:高度变为200像素
},300)
},500)
})
$('#sendMessage').on('click',function(){ //绑定事件
//百叶窗切换效果
$('.message').eq(3).hide('blind',500); //第3个元素隐藏,动画为盲目效果,动画时间为500毫秒
})
$('#sendMessage').on('click',function(){ //绑定事件
//输入框高度还原
$('textarea').animate({ //选择所有的textarea元素,并进行动画
height:'80px' //动画属性:高度变为80像素
},300);
})
$('#sendMessage').on('click',function(){ //绑定事件
var $html = "<li><div class='content'>"+$('#messageContent').val()+"</div></li>"; //取值并拼接字符串
if($("#messageContent").val()!=''){
setTimeout(function(){
//显示到评论列表第一行
$('.message').prepend($html); //将拼接好的字符串添加到class为message的元素的最前面
//当内容为空时,不能添加到留言区域
$("textarea").val("");
},1000) //1秒后执行
}
})
```
这段代码是一个基于jQuery的事件绑定,当用户点击页面上的某个元素时,会执行相应的代码块。具体解释如下:
- `$('#messageContent').on('click',function(){...})` 绑定了一个点击事件,当 `#messageContent` 元素被点击时,执行相应的代码块。
- `$('.message').eq(3).hide('blind',500)` 选中所有class为message的元素,并通过eq(3)方法选择第四个元素,然后使用hide('blind',500)方法将该元素隐藏,动画效果为盲目效果,动画时间为500毫秒。
- `$('textarea').animate({...},300)` 选中所有的textarea元素,并进行动画,将文本输入框的高度变为200像素,动画时间为300毫秒。
- `$('#messageContent').val()` 获取id为messageContent的元素的值。
- `$('.message').prepend($html)` 将拼接好的字符串添加到class为message的元素的最前面。
- `$("textarea").val("")` 清空textarea中的值。
需要注意的是,这段代码可以优化,因为存在冗余的事件绑定和代码重复。
