我正在学习 AJAX。我正在尝试在没有
<input type="submit">POST http://127.0.0.1:5000/submit 500 (INTERNAL SERVER ERROR)在运行我的 python 文件的命令提示符下显示错误。
jinja2.exceptions.TemplateSyntaxError: expected token 'end of print statement', got 'key'在主要或根 html 页面中：
<form id="myForm" action="/submit" method="POST" style="display: none;">
<input type="hidden" name="name" value="Any_name">
<input type="hidden" name="class" value="Any_class">
</form>
<button onclick="submit()">Submit</button>
JavaScript代码：
function submit() {
var xhr = new XMLHttpRequest();
xhr.open('POST', '/submit');
xhr.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded');
xhr.onload = function() {
if (xhr.status === 200) {
console.log('Data submitted successfully');
window.location.href = '/submit';
} else {
console.log('Error submitting data');
}
};
xhr.send(new FormData(document.getElementById('myForm')));
};
Python代码：
@app.route("/submit", methods=['POST'])
def submit():
data = request.form.to_dict()
return render_template("result.html", result = data)
在哪里，result.html :
<body>
{{ for key,value in result.items() }}
<p>{{ key }} : {{ value }}</p>
{{ endfor }}
</body>
您正在使用
{{}}{%%}<body>
{% for key,value in result.items() %}
<p>{{ key }} : {{ value }}</p>
{% endfor %}
</body>
