template.html
<div class="form-group col-sm-12 col-md-12">
<label for="id_amount_in_figure">Amount in figure:</label>
<input type="number" name="amount_in_figure" id="id_amount_in_figure">
</div>
<div class="form-group col-sm-12 col-md-12">
<label for="id_amount_in_word">Amount in word:</label>
<input type="text" name="amount_in_word" id="id_amount_in_word">
</div>
这是我使用 python 将数字转换为单词的代码。
def figures_to_words(figure):
# ... suppressed for brevity
return ' '.join(words)
return words
有没有一种方法可以让我有一个像上面这样的功能，只要有人在字段图中的金额中输入数字并按下选项卡按钮，然后按下下面的字段，即< em>word中的金额应该自动填写吗？
最佳答案
这可以使用 jquery 来实现。这是一个 jquery 函数。该函数将

关于javascript - 有没有办法使用 jQuery 自动完成一个字段相对于另一个字段？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/48883298/
