使用QtWebkit的javascript桥接器,我创建了一个类来将我的Web框架中的数据与我的其他Qt代码进行交互。它识别对象,但没有识别它的方法。
mainwindow.cpp代码:
#include "app.h"
MainWindow::MainWindow(QWidget *parent) : QWebView(parent)
{
happ = new app(this);
m_network = new QNetworkAccessManager(this);
page()->setNetworkAccessManager(m_network);
QFile file("E://qt//test.happ//index.html");
file.open(QIODevice::ReadOnly | QIODevice::Text);
QTextStream in(&file);
QString htmlContent = in.readAll();
addJSObject();
QObject::connect(page()->mainFrame(), SIGNAL(javaScriptWindowObjectCleared()),this, SLOT(addJSObject()));
setHtml(htmlContent);
}
void MainWindow::addJSObject()
{
page()->mainFrame()->addToJavaScriptWindowObject(QString("happ"), happ);
};
app.h代码:
#include <QObject>
class app:public QObject
{
public:
app(QObject *parent);
public slots:
void os_foo();
signals:
void win_bar();
};
的javascript:
function a(){
if(window.happ){
alert("obj: " + typeof happ); //shows "obj: object"
alert("os_foo: " + typeof happ.os_foo); //shows "os_foo: undefined"
}
}
javascript无法调用app类的功能,你帮帮我谢谢
答案 0 :(得分:0)
您是否尝试在正常(即非插槽功能)上使用Q_INVOKABLE
?试试这个
class app:public QObject
{
public:
app(QObject *parent);
//public slots:
Q_INVOKABLE void os_foo();
signals:
void win_bar();
};
然后从JavaScript coode中调用该函数。
通常这种方法适合我。不过,我从未合并Q_SLOT
和Q_INVOKABLE
。
