Question

我想做的是将onchange事件绑定到未附加的元素。但这是我尝试过的：

class WrapperCell(tf.nn.rnn_cell.RNNCell):
    """A Wrapper for a non recurrent component that feeds into an RNN."""

    def __init__(self, model_fn, out_shape, reuse=None):
        super(WrapperCell, self).__init__(_reuse=reuse)
        self.out_shape = out_shape
        self.model_fn = model_fn

    @property
    def state_size(self):
        return tf.TensorShape([1])

    @property
    def output_size(self):
        return tf.TensorShape(self.out_shape)

    def call(self, x, h):
        mod = self.model_fn(x)
        return mod, tf.zeros_like(h)

但是这不起作用，我如何将on change事件绑定到尚未附加的元素？

您需要将jQuery对象直接存储在变量中，并将事件处理程序附加到该变量，而不是HTML：

var $container = $('.test');
let input = $(`<input class="form-control" type="number" name="test" step="any" min="0">`);

input.on('change', function(e){
    console.log('test');
});

$container.html('');
$container.append(input);

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="test"></div>

绑定更改事件以输入
