Bottle.py：通过javascript发送数据

基本上，我想在我的网站上有一个交互式按钮，单击该按钮时，会将一些数据发送到服务器以便检查并显示响应（无需发送表单/页面重新加载）。

我认为这会是这样的：

function checkData()
{
    var req = new XMLHttpRequest();
    var conf = document.getElementById('my_text_area').value;

    req.open("GET", 'check_data', true);
    req.onreadystatechange = function () 
    {
        var pre = document.getElementById('check_data_out');
        pre.innerHTML = req.responseText;
    }

    req.send(conf);
    return false;
}

在服务器端：

@get('/check_data')
def check_data():
    # Process the content and answer something...
    content = str(request.is_ajax) + ' - ' + str(request.GET) + ' - ' + str(request.POST)
    return content

但这显然不起作用。这要么不是通过 javascript 发送数据的正确方法，要么不是在 Bottle.py 中访问数据的正确方法。

向我展示它是如何工作的我非常感激。

Basically, I want to have an interactive button on my website, that, when clicked, sends some data to the server in order to be checked and display the response (without form sending / page reload).

I thought it would be something like:

function checkData()
{
    var req = new XMLHttpRequest();
    var conf = document.getElementById('my_text_area').value;

    req.open("GET", 'check_data', true);
    req.onreadystatechange = function () 
    {
        var pre = document.getElementById('check_data_out');
        pre.innerHTML = req.responseText;
    }

    req.send(conf);
    return false;
}

And on the server side:

@get('/check_data')
def check_data():
    # Process the content and answer something...
    content = str(request.is_ajax) + ' - ' + str(request.GET) + ' - ' + str(request.POST)
    return content

But this obviously doesn't work. Either it is not the right way to send data via javascript or not the right way to access it in bottle.py.

Showing me how it works is highly appreciated.

您可以将 dojo 用于客户端逻辑。

var button = dojo.byId('button_id'); // button_id refers to the id of the button you want to click

dojo.connect(button,'onclick',dojo.xhrGet({
   url: '/check_data',
   handleAs : 'text',
   load : function(response){
       dojo.byId('button_id').innerHTML = response; 
   }
}));

You can use dojo for client side logic.

var button = dojo.byId('button_id'); // button_id refers to the id of the button you want to click

dojo.connect(button,'onclick',dojo.xhrGet({
   url: '/check_data',
   handleAs : 'text',
   load : function(response){
       dojo.byId('button_id').innerHTML = response; 
   }
}));
