在textarea中按Enter键提交值,按Shift + Enter键应转到下一行 [英] Submit value on pressing Enter in textarea and pressing Shift+Enter should go to next line
问题描述
我想要一个聊天框(textarea),如果用户按Enter键,则应提交聊天,如果用户按Shift + Enter,则应输入新行。
I want to have a chat box (textarea) where if user press Enter then it should submit the chat, and if user press Shift+Enter then it should enter in a new line.
我尝试了一些但却无法弄清楚确切的keyup或keydown事情。我目前使用的代码是:
I tried something but not able to figure out the exact keyup or keydown thing. The code I'm using at the moment is:
$("textarea").keydown(function(e){
if (e.keyCode == 13 && !e.shiftKey)
{
e.preventDefault();
}
});
当我按下Enter + Shift键时,我想让 \ n
到位。
Also I want to get the \n
in place when Enter+Shift key is pressed.
编辑
我的代码问题是: -
Issue with my code is:-
当我使用alert检查客户端上的内容时,它会显示下一行。但是当我发布它时,我的轨道会结束。然后它只是一个简单的字符串。没有新线路。
When i am check the content on client using using alert then it shows the next line. But when i am posting it my rails back end. Then its just a simple string. No new line thing is there.
这就是我向rails服务器发送聊天的方式。
This is how i am sending chats to rails server.
$.post("/incomingchat", { body:$("#chat_" + group_id).val() },
function(data){
// do something..
});
推荐答案
我之前已经回答了这个问题。如果插入符号不在textarea的末尾,这有点棘手:
I've answered this before. It's a little tricky if the caret is not at the end of the textarea:
