groovy.lang.MissingPropertyException：没有这样的属性：类的列数：Script1

Question

i have a list like below

List<WebElement> Cols = Rows.get(i).findElements(By.tagName('td'))

I have a method like below

 public def queryGenerator(Map inputs)
{
    def firstvalue = 'Cols.get('
    def Secondvalue = ').getText().equals('
    def thirdvalue = ')'
    def ampersand = '&'
    def value = ''

    inputs.each({ def k, def v ->
        int inum = Integer.parseInt(k);
        value = value + firstvalue+(inum-1)+Secondvalue+"\'$v\'"+thirdvalue+ampersand

    })
    return value.substring(0, value.length()-1)

}

Now I am going to use Eval from groovy to convert this expression

String x = queryGenerator(values) //This will return Cols.get(0).getText().equals("some value")
if(Eval.me(x){}

This gives following error

groovy.lang.MissingPropertyException: No such property: Cols for class: Script1

I have checked the groovy documentation most of Eval are using String, Object and Expression. Is there any way so that Eval can recognise the list.

Answer 1

One possible explanation is that you are running this from a groovy script (ie just a xxx.groovy file with code directly in the file without any class declarations). If so, please see for example this stackoverflow answer for information on the scoping of variables in groovy scripts.

Long story short, you this is a groovy script you can try:

Cols = Rows.get(i).findElements(By.tagName('td'))

(ie without the initial type declaration) or

import groovy.transform.Field
...    
@Field List<WebElement> Cols = Rows.get(i).findElements(By.tagName('td'))
