Execute javascript within webpage with selenium WebDriver

I am trying to execute a javascript method on a webpage with the selenium WebDriver. I am able to execute my own script on the page, but not call the method from the page’s HTML. Here is the HTML
function Search(){
if(check([0], “searchResults”)){
var fieldCode = “”;
var fieldText = “”;
if(([0]. elements[‘rNumber’] ==””) && (! isPRRNoSelected()))
{
alert(‘PRR No. must be a selected field. ‘);
unSelectAllOptions([0]. availableFieldsListArray);
unSelectAllOptions([0]. selectedFieldsList);}
else
[0]. = “false”;
[0] = “”;
[0]();}}}
If i attempt to submit the form manually it does not load properly. I can execute my own javascript using the code below. How can I execute the “Search” function from the page?
JavascriptExecutor js = (JavascriptExecutor)driver;
js. executeScript(“tElementById(‘fromIssueDate’). removeAttribute(‘readOnly’)”);

First of all you shouldn’t execute javascript using WebDriver unless you really have no other option. Why doesn’t the submit work? what did you try? In my experience sometimes click doesn’t trigger form submission, so instead you use submit on the form element. Note that if you submit on a non-form element its a no-op. So something like below should work,
WebElement email = ndElement((“email”));
WebElement password = ndElement((“password”));
WebElement submit = ndElement((“submit”));
ndKeys(“John”);
ssword(“foo”);
();
Going back to your original question, is Search() a global function? Then you could do something like below, however like I said, WebDriver doesn’t recommend you invoke javascript since that’s not how real users would interact with your application
js. executeScript(“();”);

Selenium WebDriver and Execute JavaScript – Python Tutorial

You can execute Javascript with the Selenium WebDriver. In this tutorial you will learn how you can run js directly from your Python code.
You an use selenium to do automated testing of web apps or websites, or just automate the web browser. It can automate both the desktop browser and the mobile lenium webdriver can execute Javascript. After loading a page, you can execute any javascript you want. A webdriver must be installed for selenium to work.
All it takes to execute Javascript is calling the method execute_script(js) where js is your javascript code.

javascriptWhat is JavaScript? JavaScript is a scripting languages that was made to run on top of websites (client side). It used to be to only make a webpage interactive, but these days there are complete frameworks that let you build the front-end of apps.
How to Execute Javascript? Before you can use selenium, make sure it is installed and that you also have the right web driver. You can initialize selenium the way you always do.
If you load a website with Python selenium, you can manually inject JavaScript onto that page. If you named your webdriver object driver, then you can execute it like so:
1driver. execute_script(“some javascript code here”);
The program below runs a one line javascript command after loading the page. This will show the alert box in the webpage.
1234567from selenium import refox()plicitly_wait(3)(“)js = ‘alert(“Hello World”)’driver. execute_script(js)
This means you can also use Javascript inside selenium to click on items, like on a button.
1234from selenium import webdriverdriver = refox()(“) driver. execute_script(“tElementsByClassName(‘comment-user’)[0]()”)
To scroll the browser window, you can use Javascript too:
1driver. execute_script(“rollTo(0, );”
But of course, you can also do this the Pythonic way by using the selenium module instead.
If you are new to selenium, then I highly recommend this book.

Most web-pages and web-applications heavily utilize JS. And it’s possible to interact with an application on a very complex level by using JavaScript scripts. It’s really, a very powerful tool. A way to turn a good tool into a great one, however, is to use it to enhance automated testing with rtunately, Selenium already has really deep connections with JavaScript to perform some interactions with web applications. And it allows a user to execute any JS script on a current page by invoking executeScript or executeAsyncScript methods of its JavaScriptExecutor execution methodsSo, as stated above, there are two methods that can execute your JS script: executeScript and executeAsyncScript. All of them have a common syntax:((JavascriptExecutor) driver). executeScript(Script, Arguments);Where the driver is your Selenium WebDriver, Script is your JavaScript as String, and Arguments are arguments, you want to pass to the script, accessible via arguments magic variable. Arguments for the script must be a number, a boolean, a String, a WebElement, or a List of any combination of the ‘s take a closer look at each of them. executeScriptExecutes JavaScript in the context of the currently selected frame or window via anonymous Selenium function. To get access to a current page DOM, you can use a document your script returns any value you can assign it to a variable, using types as follows:WebElement – if your script returns an HTML elementDouble – if it’s a decimal numberLong for non-decimal numbersBoolean for a boolean valueString – all the other casesYour script can also return List
