textarea {width:300px; min-height:60px; overflow:hidden;} 3.加入自适应的JS $.fn.autoHeight = function(){ function autoHeight(elem){ elem.style.height = 'auto'; elem.scrollTop = 0; //防抖动 elem.style.height = elem.scrollHeight + 'px'; } this.each(function(){ autoHeight(this);...
textarea根据内容自动适应 为textarea添加 autoHeight 属性即可 autoHeight="true" */$(function(){$.fn.autoHeight=function(){functionautoHeight(elem){elem.style.height='auto';elem.scrollTop=0;elem.style.height=elem.scrollHeight+'px';}this.each(function(){autoHeight(this);$(this).on('keyup',...

一个一个的加或者调用封装函数? 不用,可以在计算高度的时候获取多个,并循环计算: functiontextareaH(){letobj=$('textareaClass'),len=obj.length;for(leti=0;i<len;i++){// console.log(obj[i]);obj[i].style.height='auto';obj[i].style.height=obj[i].scrollHeight+'px';}} 1. 2. 3. 4...

minRows、maxRows:设置文本框的最小行数和最大行数。 使用示例如下: importReact,{Component}from'react';importTextareaAutosizefrom'react-textarea-autosize';classAppextendsComponent{handleBlur=(e)=>{console.log('失去焦点',e.target.value);}handleChange=(e)=>{console.log('值变化',e.target.value)...
