使用Java中的字符串动态生成硒查询

Question

I was trying to generate a selenium query dynamically as follows but it did not work:

String Query = "By."+Selector+"("+Expression+")))";

element = wait.until(ExpectedConditions.elementToBeClickable(Query));

How to achieve this requirement please?

Answer 1

According to the documentation and the error you are getting, there does not seem to exist an elementToBeClickable method which takes a string as parameter.

Checking the By documentation however, which seems to be one of the input parameters which the method you are after takes, one can see that they can construct it from a string.

In short, your code would need to change to something like so:

String cssQuery = ... //You can construct the CSS query dynamically.
element = wait.until(ExpectedConditions.elementToBeClickable(By.cssSelector(cssQuery)));

Answer 2

Looks like you want to get an element By query, using selector and expression parameters and then pass result to ExpectedConditions. So may be you need universal method for this?

Like:

public By getSeleniumQuery(String selector, String expression){
    if(selector.equalsIgnoreCase("id")){
        return By.id(expression);
    }
    else if(selector.equalsIgnoreCase("name")){
        return By.name(expression);
    }
    else if(selector.equalsIgnoreCase("class")){
        return By.className(expression);
    }
    else if(selector.equalsIgnoreCase("css")){
        return By.cssSelector(expression);
    }
    else if(selector.equalsIgnoreCase("link")){
        return By.linkText(expression);
    }
    else if(selector.equalsIgnoreCase("partialLink")){
        return By.partialLinkText(expression);
    }
    else if(selector.equalsIgnoreCase("tag")){
        return By.tagName(expression);
    }
    else if(selector.equalsIgnoreCase("xpath")){
        return By.xpath(expression);
    }
    else{
        throw new IllegalArgumentException("Unknown selector - " + selector);
    }
}
