injectJs
injectJs(filename) {boolean}
Injects external script code from the specified file into the page (like page.includeJs, except that the file does not need to be accessible from the hosted page).
If the file cannot be found in the current directory, libraryPath is used for additional look up.
This function returns true if injection is successful, otherwise it returns false.
Examples
Inject do.js file into phantomjs.org page
var webPage = require('webpage');
var page = webPage.create();
page.open('http://www.phantomjs.org', function(status) {
if (status === "success") {
page.includeJs('http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js', function() {
if (page.injectJs('do.js')) {
var title = page.evaluate(function() {
// returnTitle is a function loaded from our do.js file - see below
return returnTitle();
});
console.log(title);
phantom.exit();
}
});
}
});
Where do.js is simply:
window.returnTitle = function() {
return document.title;
};
The console log will be:
"PhantomJS | PhantomJS"
Note: The arguments and the return value to the evaluate function must be a simple primitive object. The rule of thumb: if it can be serialized via JSON, then it is fine.
Closures, functions, DOM nodes, etc. will not work!
