There is no context for answer to your question.
Please, give us more details about the context, where and when you want to change the variable... otherwise the only answer can be:
"just do it" :-)

@name = "john";@

In javascript.js file contains :
var ItemName="coldrinks";
var ItemValue="100";
function myfunction()
{
document.getElementById('nItemValue')[removed]=ItemValue;
document.getElementById('nItemName')[removed]=ItemName;
}

In my Qt program;

QString nItemName ="potato chips";
QString nItemPrice = 20;

QUrl iUrl=Url::fromLocalFile((QDir::current().absoluteFilePath("./html_pages/alert_item_recognized.html")));
ui->webView->settings()->clearMemoryCaches();
ui->webView->load(iUrl);
ui->webView->show();

I want to just know any method for edit javascript file before alert_item_recognized.html opened. I want to edit contents of javascript.js..

before html page loads javascript file should edit with
var ItemName="potato chips";
var ItemValue="20";
