Question

我一直试图找到一种方法来复制此表单及其输入字段几天。我尝试过使用我发现here的代码，但无济于事。如何复制此表单？

HTML

<form action="dilemman.php" method="post" class="copy" enctype="multipart/form-data">
    Video: <br>
    <input type="text" rows="1" cols="40" name="video"></textarea>
    <div class="input_fields_wrap">
        <button class="add_field_button">Lägg till fler svar</button>
    </div>
    <a href="#" class="copy" rel=".form">Duplicate form</a>
</form>

的Javascript

var removeLink = ' <a class="remove" href="#" onclick="$(this).parent().remove(); return false">remove</a>';
$('a.copy').relCopy({limit: 5, append: removeLink});

Answer 1

Html：

 <button onclick="myFunction()">Duplicate form</button>

JS：

 function myFunction() {
        var elmnt = document.getElementById("formid");
        var cln = elmnt.cloneNode(true);
        document.body.appendChild(cln);
    }

Answer 2

你只能使用jquery，不需要使用relCopy ..

var cp = $('form.copy').html();
$('a.copy').on('click', function(){
    $('form.copy').append( cp );
})

快速查看relCopy文档，您必须使用rel元素中的a属性定位表单，而不是<form action="dilemman.php" method="post" class="copy"元素。

<a href="#" class="copy" rel=".form">Duplicate form</a>

<form action="dilemman.php" method="post"

更改为

class="form"的 <a href="#" class="copy" rel=".form">Duplicate form</a>

#include <boost/program_options.hpp> // ... using namespace cv; using namespace std; namespace po = boost::program_options; int signModule(int argc, char** argv); int kfModule(int argc, char** argv); int main(int argc, char** argv) { string helpText = "You need to specify a module:\n\tprogram [sign|kf]\n\nUse program <module> --help for a description."; if (argc < 2) { // Then no module was given cout << helpText << endl; return -1; } string module = argv[1]; // This is the first argument. Index 0 holds the executable // Copy argv but exclude argv[1} int moduleArgC = argc -1; char* moduleArgV[moduleArgC]; moduleArgV[0] = argv[0]; for(int i=1; i < moduleArgC ;++i) { moduleArgV[i] = argv[i+1]; } if (module == "sign") return signModule(moduleArgC, moduleArgV); else if (module == "kf") return kfModule(moduleArgC, moduleArgV); else { // default cout << "Unknown module: " << module << "\n\n" << helpText << endl; return -1; } } int signModule(int argc, char** argv) { try { po::options_description desc("Allowed options"); desc.add_options() ("help,h", "produce help message") ("circle,c", po::value<string>(&recognizer::circleClassifierFilePath)->default_value(recognizer::circleClassifierFilePath), "Path to CircleClassifier") ("triangleUp,t", po::value<string>(&recognizer::triangleClassifierFilePath)->default_value(recognizer::triangleClassifierFilePath), "Path to TriangleUpClassifier") ("winSize,w", po::value<int>()->default_value(recognizer::winSize.width), "WinSize of HOGDescriptor as int") ("createHog", po::bool_switch(&recognizer::createHogFeaturesFromImages)->default_value(recognizer::createHogFeaturesFromImages), "Specifies if HOG features will be created even if HOG file is present.") ("svmKernel", po::value<int>(&recognizer::svmKernel)->default_value(recognizer::svmKernel), "The SVM kernel of the classifiers. LINEAR =0, POLY =1, RBF =2, SIGMOID =3, CHI2 =4, INTER =5") ("degree", po::value<double>(&recognizer::degreeOfPolyKernel)->default_value(recognizer::degreeOfPolyKernel), "The degree for the polynomial SVM kernel. Makes only sense with option --svmKernel=1 (POLY).") ; po::variables_map vm; po::store(po::command_line_parser(argc, argv). options(desc).run(), vm); po::notify(vm); if (vm.count("help")) { cout << "Usage: program [options]\n"; cout << desc; return 0; } // Validate options if (vm.count("winSize")) { int winSize = vm["winSize"].as<int>(); recognizer::winSize = Size(winSize, winSize); } if (vm["svmKernel"].as<int>() < 0 || 5 < vm["svmKernel"].as<int>()) { cout << "Wrong svmKernel:\t" << vm["svmKernel"].as<int>() << "\tAllowed values: LINEAR =0, POLY =1, RBF =2, SIGMOID =3, CHI2 =4, INTER =5" << endl; return 1; } } catch(std::exception& e) { cout << e.what() << "\n"; return 1; } SignClassifier::createClassifier(); return 0; } int kfModule(int argc, char** argv) { // Another module with different options // ... return 0; }
