Qt加载HTML/js，实现相互调用的小程序（源码）

#include "mainwindow.h" #include "ui_mainwindow.h" #include <QWebChannel> #include <QWebEnginePage> #include "InteractionObjectt.h" MainWindow::MainWindow(QWidget *parent) : QMainWindow(parent) , m_itobj(new InteractionObject(this)) , ui(new Ui::MainWindow) { ui->setupUi(this); QWebChannel *channel = new QWebChannel(this); //注册一个content 这里的内容通过JS的content来获取 channel->registerObject(QString("content"),m_itobj); ui->widget->getWebEnginePage()->setWebChannel(channel); connect(m_itobj,&InteractionObject::receText,this,&MainWindow::onReceText); connect(ui->sendQt,SIGNAL(released()),this,SLOT(onSendBtn())); } MainWindow::~MainWindow() { delete ui; } void MainWindow::onSendBtn() { m_itobj->sendText(ui->userEdit->text(),ui->pwdEdit->text()); ui->userEdit->setText(""); ui->pwdEdit->setText(""); } void MainWindow::onReceText(const QString &r_user, const QString &r_pwd) { ui->userEdit->setText(r_user); ui->pwdEdit->setText(r_pwd); }
