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 "$ "
}
