问题描述
我有这样的表格:
<form method="post">
<input type="text" name="msg" id="chat_in" >
<input type="button" name="bt" id="bt">
</form>
我想在用户按下回车或点击按钮时发送数据
i want to send data when user pressing enter or clicking on button
当用户点击按钮时它会起作用,但是当用户按下上的输入
it's work when user click on button , but it doesn't work when user pressing enter on chat_in
这里是我的javascript:
here is my javascript :
$(document).ready(function () {
function SendData() {
$.ajax({
url: "save.php",
type: "post",
data: "msg="+$('#chat_in').val(),
dataType: 'json',
success: function(){
alert("Sent");
},
error:function(){
alert("failure");
}
});
}
$('#chat_in').keypress(function(e) {
if(e.which == 13) {
alert('You pressed enter!');
SendData();
}
});
$('#bt').click(function() {
SendData();
});
});
我该如何解决这个问题?
how can i solve this problem ?
推荐答案
如果有人遇到同样的问题,只需删除表格
并使用按钮
if anyone have same problem , just remove form
and use button
在这种情况下你的html和javascript应该是这样的:
in this case your html and javascript should be something like this :
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>final</title>
<script type="text/javascript" src="jquery-1.4.3.min.js"></script>
<script>
$(document).ready(function() {
function SendData() {
$.ajax({
url: "save.php",
type: "post",
data: "msg="+$('#chat_in').val(),
dataType: 'json',
success: function(){
alert("Sent");
},
error:function(){
alert("failure");
}
});
}
$('#chat_in').keypress(function(e) {
if(e.keyCode == 13) {
alert('You pressed enter!');
SendData();
}
});
$('#bt').click(function() {
SendData();
});
});
</script>
</head>
<body>
<input type="text" name="msg" id="chat_in" >
<input type="button" name="bt" id="bt">
</body>
</html>
