Tips for efficiently handling large volumes of JavaScript code in Selenium:

Dealing with the library selenium is really becoming exhausting. If you need to inject JavaScript code into Selenium, try this:

`js = "Enter your JS code here"
driver.excute_script(js)`

However, my JavaScript code contains multiple lines, like this:

setTimeout(function(){l = document.getElementsByClassName("test-option");for(const a in l){if(l[a]==undefined || l[a]==null)continue;if(l[a].innerText !=undefined && l[a].innerText.includes("Miracle")){l[a].click();}}, 2000);

When I remove the newline characters and concatenate the lines using single or double quotes, Selenium starts behaving unpredictably. Is there a more effective way to pass JavaScript strings to Selenium? Thank you.

Answer №1

Despite the potential messiness, this issue should not pose a significant problem:

driver.execute_script("""
  setTimeout(function(){
    let options = document.getElementsByClassName("test-option");
      for(const option in options){
        if(options[option]==undefined || options[option]==null)
            continue;

        if(options[option].innerText !=undefined && options[option].innerText.includes("Miracle")){
          options[option].click();
        }
    }
  }, 2000)
""")
