python和js交互调用的办法
后台代码都是应用的
1.【get办法】运用jquery的get json与后台交互
前端js代码片段
var data= {
‘a’: $(‘input[name=“a”]’).val(),
‘b’: $(‘input[name=“b”]’).val()
}
.
g
e
t
J
S
O
N
(
.getJSON(
.getJSON(script_ROOT + ‘/_add_numbers’,data, function(data) {
$(’#result’).text(data.result);
$(‘input[name=a]’).focus().select();
});
后端pthon代码如下
“”“Add two numbers server side, ridiculous but well…”""
a = request.args.get(‘a’, 0, type=int)
b = request.args.get(‘b’, 0, type=int)
log.info(a)
log.info(b) return jsonify(result=a + b)
2.【万能方式】运用jquery的ajax与后台交互，设置不同的参数，能够get也能够post
上面的例子用ajax方式，前端代码如下
var data= {
‘a’: $(‘input[name=“a”]’).val(),
‘b’: $(‘input[name=“b”]’).val()
}
{#
.
g
e
t
J
S
O
N
(
.getJSON(
.getJSON(script_ROOT + ‘/_add_numbers’,data, function(data) {#}
{# $(’#result’).text(data.result);#}
{# $(‘input[name=a]’).focus().select();#}
{# });#}
$.ajax({
type: ‘get’,
url: $script_ROOT + ‘/_add_numbers’,
data: data,
contentType: ‘application/json; charset=UTF-8’,
dataType: ‘json’,
success: function(data) {
$(’#result’).text(data.result);
$(‘input[name=a]’).focus().select();
},
error: function(xhr, type,xxx) {
alert('error ')
}
});
后台代码不便仍然是
“”“Add two numbers server side, ridiculous but well…”""
a = request.args.get(‘a’, 0, type=int)
b = request.args.get(‘b’, 0, type=int)
