QWebView not loading external javascript?

Question

It is possible to load an external javascript file from the html using QWebView?

In the following QtProject (all files in the same directory) there is javascript cod

Answer 1

Alternatively 1:

It seems the javascript isn't evaluated from the html. In other words, the following has no effect:

<script type="text/javascript" src="qt.js">
</script>

It must be done explicitly:

QString js = readFile("qt.js");
view->page()->mainFrame()->evaluateJavaScript(js);

And, there is no need to set baseUrl in setHtml().

Alternatively 2:

Use the QRC System and set the baseUrl in setHtml. This way doesn't require a call to view->page()->mainFrame()->evaluateJavaScript();

//    QString js = readFile(":/qt.js");
//    view->page()->mainFrame()->evaluateJavaScript(js);

    QString html = readFile(":/qt.html");
    view->setHtml(html, QUrl("qrc:/"));

application.qrc

<!DOCTYPE RCC><RCC version="1.0">
<qresource>
    <file alias="qt.png">resource/qt.png</file>
    <file alias="image.html">resource/image.html</file>
    <file alias="qt.html">resource/qt.html</file>
    <file alias="qt.js">resource/qt.js</file>
</qresource>
</RCC>

Answer 2

If you want to load a local html file, first you need to change the src attribute of the javascript, for example:

then src is changed to src="'file:///D:/home/myWeb/js/myjs.js'"

this will work. Relative path can also be given.

Answer 3

Actually you can. You just need to add file:// at the begining of your src.

file:///home/js/somejs.js
