我試着去使用AJAX輸出到paramas文本文件的代碼,但不工作sinatra輸出參數爲文本文件?
我不知道,因爲它不工作
我使用的打印參數驗證碼
f.write PARAMS [ :名字]
require 'sinatra'
require 'pp'
get '/' do
erb :index
end
get '/2' do
content_type 'text/javascript'
File.read(File.join('public', 'jquery-1.7.1.js'))
end
post '/greeting' do
puts "params"
#pp params
"<p>#{params[:salutation]}, #{params[:name]}</p>"
end
post '/greeting' do
puts "params"
#pp params
File.read(File.join('public', 'name_of_the_file.txt'))
File.open('name_of_the_file.txt', 'w') do |f|
f.write params[:name]
end
end

<html>
<head>
<script src="/2"></script>
<script type="text/javascript">
$(document).ready(function() {
ax=2;
$('body').on("click reset",function(e){ ax= e.target.value ; });
ax=2;
$.post("greeting", { salutation: ax, name: "Friend" },
function(result) { $("#greeting").html(result);
});
});
</script>
</head>
<body>
<h1>Sinatra Ajax Demo using jQuery</h1>
<label for="male">Male</label>
<input type="radio" name="gender" id="male" value="male"><br>
<label for="female">Female</label>
<input type="radio" name="gender" id="female" value="female"><br>
<label for="other">Other</label>
<input type="radio" name="gender" id="other" value="other"><br><br>
<input type="submit" value="Submit">
<div id="greeting">
<p>Hello, World</p>
</div>
</body>
</html>
請幫我解決這個問題
您可以使用解決'把params'看名字是否不存在? –
是的,我在控制檯中看到{「salutation」=>「2」,「name」=>「Friend」} – zzero
