textarea的属性wrap="hard"可以把换行的内容也存起来。
<html>
<head>
<title>这是一个小测试</title>
<meta name="" content="" charset="utf-8" />
<meta name="viewport" content="width=device-width,initial-scale=1,minimum-scale=1,maximum-scale=1,user-scalable=no" />
</head>
<body>
<div class="">
<textarea name="" rows="10" cols="100" wrap="hard"></textarea>
</div>
<div class="">
<button class="btn1">点击提交</button>
<button class="btn2">点击获取</button>
</div>
<div class="content">
</div>
</body>
<script src="jq.js"></script>
<script type="text/javascript">
var getFormatCode = function(strValue) {
return strValue.replace(/
/g, '<br/>').replace(/
/g, '<br/>').replace(/s*/g, '');
}//这个js一定不能丢
$('.btn1').on('click', function() {
$.ajax({
type: "get",
url: "http://*/login?text=" + getFormatCode($('textarea').val()),
async: true,
success: function(res) {
if(res.code == 0) {
alert('提交成功')
}
}
});
})
$('.btn2').on('click', function() {
$.ajax({
type: "get",
url: "http://*/text",
async: true,
success: function(res) {
if(res.code == 0) {
$('.content').html(res.msg)
} else {
alert('fail')
}
}
});
})
</script>
</html>
这样就把多行文本的回车也存了起来
