我一直在为我的小项目开发一项新功能,该功能从输入中获取命令(写入输入:创建一个名为somename的框),如果它检测到该命令为“创建一个名为somename的框”,它将创建一个somename类的div。但是,当我尝试向#include <string>
#include <sstream>
void loginToWebsite(const std::string &url, const std::string &userAgent, const std::string &username, const std::string &password)
{
CURL *curl = curl_easy_init();
if (curl)
{
curl_easy_setopt(curl, CURLOPT_URL, url.c_str());
curl_easy_setopt(curl, CURLOPT_USERAGENT, userAgent.c_str());
curl_easy_setopt(curl, CURLOPT_POST, 1L);
std::ostringstream oss;
oss << "j_username=";
char *encoded = curl_easy_escape(curl, username.c_str(), username.length());
if (encoded)
{
oss << encoded;
curl_free(encoded);
}
oss << "&j_password=";
encoded = curl_easy_escape(curl, password.c_str(), password.length());
if (encoded)
{
oss << encoded;
curl_free(encoded);
}
std::string postdata = oss.str();
curl_easy_setopt(curl, CURLOPT_POSTFIELDS, postdata.c_str());
curl_easy_setopt(curl, CURLOPT_FOLLOWLOCATION, 1L);
curl_easy_setopt(curl, CURLOPT_MAXREDIRS, 3L);
curl_easy_setopt(curl, CURLOPT_COOKIEJAR, "cookies.txt");
CURLcode res = curl_easy_perform(curl);
// use res as needed...
curl_easy_cleanup(curl);
}
}
元素添加样式时,什么也没发生。问题出在switch语句的div
break;
// checks if word is in string s
function wordInString(s, word){
return new RegExp( '\\b' + word + '\\b', 'i').test(s);
}
$('input').keypress(function(e) {
if (e.which == 13) {
let input = $(this).val();
console.log("Initial Input: " + input);
const Commands = ['call it', 'name it', 'make a box called'];
split_input = input.split(" ");
var arrayLength = Commands.length;
for (var i = 0; i < arrayLength; i++) {
command = Commands[i];
console.log(command);
let wordFound = wordInString(input, command);
if (wordFound) {
console.log("Command found: " + command)
switch (command) {
case "make a box called":
let name = split_input[4];
console.log("Box name: " + name)
$('.Dragon').append($('<div>', {class: name}));
// this is the problem line, I do not quite get why it won't w ork
$('.'.concat(name)).addClass({'background-color': 'green', 'height': '50px', 'width': '50px'});
break;
default:
}
}
}
$(this).val('');
}
});
答案 0 :(得分:1)
您应该使用jquery的css()方法而不是那里的addClass,使用与
相同的语法。$('.'.concat(name)).css({'background-color': 'green', 'height': '50px', 'width': '50px'});

似乎您尝试使用错误的方法。尝试使用css
代替addClass
.addClass({'background-color': 'green', 'height': '50px', 'width': '50px'});
必须是
.css({'background-color': 'green', 'height': '50px', 'width': '50px'});

为更加清楚起见,不能使用.addClas()方法的原因是因为“ background-color”不是类,而是css属性。因此,您必须使用.css()方法进行设置。
.css({'background-color': 'green', 'height': '50px', 'width': '50px'});
