The type 'elementfinder' cannot be assigned to a parameter of type 'boolean'

Currently, I am working on a function that checks if a checkbox is selected. If it's not checked, then the function should click on it. However, I encountered an error message stating "argument of type 'elementfinder' is not assignable to parameter of type 'boolean'" when calling this function.

//variable

md5hash_checkbox = element(by.id('md5hash'));
 //To check checkbox if not selected
  selectCheckBox(checkValue: boolean){
        this.checkValue.isSelected().then(selected => {
            if (selected) {
                console.log(checkValue+': Is Already selected');
            } else {
                this.checkValue.click();
            }
        });

When calling the function like this.selectCheckBox(this.sha1hash_checkbox); I receive the error message "argument of type 'elementfinder' is not assignable to parameter of type 'boolean'"

Answer №1

isSelected() is only applicable to ElementFinder, not a regular boolean. To properly handle this situation, the following code snippet should be used:

selectCheckbox(): void {
  el:ElementFinder =  element(by.id('md5hash'));
  el.isSelected().then(selected => {
    if (selected) {
        console.log(el + ': Is Already selected');
    } else {
        el.click();
    }
  });
}

Answer №2

toggleCheckbox() requires a web element as an argument, so you should specify the argument type as ElementFinder instead of boolean. Here's how it should look:

toggleCheckbox(targetElement: ElementFinder) {
  // Click the checkbox only if it is not already selected
  targetElement.isSelected().then(selected => {
    if (selected) {
      console.log('Checkbox already selected');
    } else {
      targetElement.click();
    }
  });
}

md5hash_checkbox = element(by.id('md5hash'));
toggleCheckbox(md5hash_checkbox);
