Question

我使用python 2.7，并且当我点击某个按钮，使用flask时，我想在HTML中为输入文本字段设置值。这该怎么做？

def submit_textarea():
    text = request.form.get("text")
    outfile = codecs.open('output.txt', 'w', 'utf-8')
    outfile.write(text)

    return render_template("index.html")

此函数获取文本并将其发送到文本文件我想为其他输入文本字段设置一些文本。

我不完全确定我是否理解你的问题，但我认为这就是你要做的......

index.html

如您所见，文本字段的名称为<form action="/get-text" method="POST"> <input type="text" name="first_name"> <input type="submit" value="Go"> </form>。

first_name

app.py

当您在变量@app.route('/get-text', methods=['GET', 'POST']) def foo(): bar = request.form['first_name']中按GO时，此示例将存储键入文本输入的内容。

如何使用flask设置输入文本的值？
