这是我的文件的样子:
{
"JObjects": {
"JArray1": [
{
"A": "a",
"B": "b",
"C": "c"
},
{
"A": "a1",
"B": "b2",
"C": "c3",
"D": "d4"
"E": "e5"
},
{
"A": "aa",
"B": "bb",
"C": "cc",
"D": "dd"
}
]
}
}
这是我走了多远:
JSONObject object = new JSONObject("json-file.json");
JSONObject getObject = object.getJSONObject("JObjects");
JSONArray getArray = getObject.getJSONArray("JArray1");
for(int i = 0; i < getArray.size(); i++)
{
JSONObject objects = getArray.getJSONArray(i);
//Iterate through the elements of the array i.
//Get thier value.
//Get the …如何使用指令方法启用/禁用锚标记？
例:
JAVASCRIPT:
angular.module('ngApp', []).controller('ngCtrl',['$scope', function($scope){
$scope.create = function(){
console.log("inside create");
};
$scope.edit = function(){
console.log("inside edit");
};
$scope.delete = function(){
console.log("inside delete");
};
}]).directive('a', function() {
return {
restrict: 'E',
link: function(scope, elem, attrs) {
if(attrs.ngClick || attrs.href === '' || attrs.href === '#'){
elem.on('click', function(e){
e.preventDefault();
if(attrs.ngClick){
scope.$eval(attrs.ngClick);
}
});
}
}
};
});
我在函数声明中多次发现这些符号,但我不知道它们是什么意思.
例:
void raccogli_dati(double **& V, double **p, int N) {
int ultimo = 3;
V = new double * [N/2];
for(int i=0; i < N/2; i++) {
V[i] = new double[N/2], std :: clog << "digita " << N/2 - i
<< " valori per la parte superiore della matrice V: ";
for(int j=i; j < N/2; j++)
std :: cin >> V[i][j], p[ultimo++][0] = (V[i][j] /= sqrt(p[i][0]*p[j][0]));
}
for(int i=1; i < N/2; i++)
for(int j=0; j < …我有一个HTML元素,其中包含大量无序列表.我需要克隆这个元素放在页面的其他地方添加不同的样式(这很简单,使用jQuery).
$("#MainConfig").clone(false).appendTo($("#smallConfig"));
但问题是,所有列表及其关联的列表项都有ID并clone重复它们.是否有一种简单的方法可以在追加之前使用jQuery替换所有这些重复的ID？
如何获取JSON数据节点中的元素数量？
JSON:
{
"result":[
{
"run":[
{
"action":"stop"
},
{
"action":"start"
},
{
"action":"start"
}
],
"find":true
}
]
}
我需要从节点获取元素的数量data['result'][0]['run'].它应该是3,但我无法在Python中找到它.
在Python中,有没有办法从另一个类调用类方法？我试图在Python中使用自己的MVC框架,我无法弄清楚如何从另一个类中的一个类调用一个方法.
这就是我想要发生的事情:
class A:
def method1(arg1, arg2):
# do code here
class B:
A.method1(1,2)
我正在慢慢从PHP进入Python,所以我正在寻找Python的Python等价物call_user_func_array().
我想iframe从网页上获取所有内容.
码:
site = "http://" + url
f = urllib2.urlopen(site)
web_content = f.read()
soup = BeautifulSoup(web_content)
info = {}
content = []
for iframe in soup.find_all('iframe'):
info['src'] = iframe.get('src')
info['height'] = iframe.get('height')
info['width'] = iframe.get('width')
content.append(info)
print(info)
pprint(content)
结果print(info):
{'src': u'abc.com', 'width': u'0', 'height': u'0'}
{'src': u'xyz.com', 'width': u'0', 'height': u'0'}
{'src': u'http://www.detik.com', 'width': u'1000', 'height': u'600'}
结果pprint(content):
[{'height': u'600', 'src': u'http://www.detik.com', 'width': u'1000'},
{'height': u'600', 'src': u'http://www.detik.com', 'width': u'1000'},
{'height': u'600', 'src': u'http://www.detik.com', …只是试图测试非常简单的Python JSON命令,但我遇到了一些麻烦.
urlopen('http://www.similarsitesearch.com/api/similar/ebay.com').read()
应该输出
'{"num":20,"status":"ok","r0":"http:\\/\\/www.propertyroom.com\\/","r1":"http:\\/\\/www.ubid.com\\/","r2":"http:\\/\\/www.bidcactus.com\\/","r3":"http:\\/\\/www.etsy.com\\/","r4":"http:\\/\\/us.ebid.net\\/","r5":"http:\\/\\/www.bidrivals.com\\/","r6":"http:\\/\\/www.ioffer.com\\/","r7":"http:\\/\\/www.shopgoodwill.com\\/","r8":"http:\\/\\/www.beezid.com\\/","r9":"http:\\/\\/www.webidz.com\\/","r10":"http:\\/\\/www.auctionzip.com\\/","r11":"http:\\/\\/www.overstock.com\\/","r12":"http:\\/\\/www.bidspotter.com\\/","r13":"http:\\/\\/www.paypal.com\\/","r14":"http:\\/\\/www.ha.com\\/","r15":"http:\\/\\/www.onlineauction.com\\/","r16":"http:\\/\\/bidz.com\\/","r17":"http:\\/\\/www.epier.com\\/","r18":"http:\\/\\/www.sell.com\\/","r19":"http:\\/\\/www.rasmus.com\\/"}'
但我得到了相同的字符串,b前面有一个字符串:
b'{"num":20,"status":"ok","r0":"http:\\/\\/www.propertyroom.com\\/","r1":"http:\\/\\/www.ubid.com\\/","r2":"http:\\/\\/www.bidcactus.com\\/","r3":"http:\\/\\/www.etsy.com\\/","r4":"http:\\/\\/us.ebid.net\\/","r5":"http:\\/\\/www.bidrivals.com\\/","r6":"http:\\/\\/www.ioffer.com\\/","r7":"http:\\/\\/www.shopgoodwill.com\\/","r8":"http:\\/\\/www.beezid.com\\/","r9":"http:\\/\\/www.webidz.com\\/","r10":"http:\\/\\/www.auctionzip.com\\/","r11":"http:\\/\\/www.overstock.com\\/","r12":"http:\\/\\/www.bidspotter.com\\/","r13":"http:\\/\\/www.paypal.com\\/","r14":"http:\\/\\/www.ha.com\\/","r15":"http:\\/\\/www.onlineauction.com\\/","r16":"http:\\/\\/bidz.com\\/","r17":"http:\\/\\/www.epier.com\\/","r18":"http:\\/\\/www.sell.com\\/","r19":"http:\\/\\/www.rasmus.com\\/"}'
随后,当我试着跑
json.loads(urlopen('http://similarsitesearch.com/api/similar/ebay.com').read())
它给了我错误信息:
TypeError:不能在类字节对象上使用字符串模式"
我假设与之有关b？
我urlopen从中导入urllib.request,我正在运行Python 3.
有任何想法吗？
