how to execute custom javascript code in webdriverjs

Question

how to execute custom javascript code in webdriverjs ( https://code.google.com/p/selenium/wiki/WebDriverJs ) I found execute method but it`s purpose is completly different.

Answer 1

Here you go:

var yourClientJSFunction = function (param1, param2) { // the JS code you want to run in the browser } driver.executeAsyncScript(yourClientJSFunction, param1, param2).then(function (res) { // deal with the response }); 

Answer 2

If you're using camme/webdriverjs on node, you can use the following snippet:

client .execute(function() { return $('ul li').length; }, [], function (err, result) { console.log(result.value); // 4 }) .call(done); 

Here, we are getting the number of list-items using jquery. We handle the result in the callback function, by accessing result.value.

It's also available as a gist here: https://gist.github.com/ragulka/10458018
