Include js files to the web app created by Qt

tham

I would like to call the js libraries by EM_JS, I try to manually include the scripts in the html file(app_name.html ) after compiled. Like

app_name.html

<scirpt src="js/config.js"><script>

js/config.js

window._config =  {

api : {

invokeUrl: 'abcd"

}

}

mainwindow.cpp

``'
EM_JS(char*, get_invoke_url, (), {
var jsString = window._config.api.invokeUrl;
var lengthBytes = lengthBytesUTF8(jsString)+1;
var stringOnWasmHeap = _malloc(lengthBytes);
stringToUTF8(jsString, stringOnWasmHeap, lengthBytes);
return stringOnWasmHeap;
})

void process_input_text::on_pushButtonSelectCharsInFile_clicked()
{
char *url = get_invoke_url();
ui->lineEditCharsInFile->setText(url);
free(url);
}


After I call the on_pushButtonSelectCharsInFile_clicked, it give me error message 

**TypError : window._config is undefined**

How should I include the js file in order to call it from c++?Thanks

@tham said in Include js files to the web app created by Qt:

<scirpt src="js/config.js"><script>

Try spelling script correctly?

@jonb Thanks, tried it, but still the same.

I include the script like

<script src='config.js'></script>
<script type='text/javascript'>
//codes generated by Qt
</script>

different part is I change window to Module
Now it complain Module._config is undefined

Wonder if it is caused by name conflict etc, so I change it to

var _global_config =  {

api : {

invokeUrl: 'abcd"

}

}

call it in EM_JS as

_global_config.api.invokeUrl

Ok, at last it works. Maybe window._config and Module._config works too, maybe I was forgot to update the html or wrong spelling etc, I am not sure, sometimes this kind of small errors are hard to spot, hope someday we could have compile time error for them.
