textarea自动换行的换行符是什么?
js中如何获得textarea的换行符?
<textarea id= "txtTest " WRAP= "hard " style= "width:200px "> </textarea>
当输入的内容自动换行之后,能否获得自动换行的换行符?
txtTest.value.indexOf( "\n ") 等于 -1,txtTest.value.indexOf( "\r ")也是等于-1
谢谢!

function a(){
alert(document.getElementById( "t ").innerText.replace( "\r\n ", "$ "));//回车换行换成 "$ "
}

<textarea id=t> </textarea>
